API BREAK

Version 1.0.0 introduces several API changes.

To port your software check our upgrade guide

The following device types are not supported going forward:

• 23G
• 23U
• 73U
• AFU130

A complete compatibility list can be found here: https://www.theimagingsource.com/documentation/tiscamera/supported-devices.html

Dependencies

Compilation

Compilation dependencies for debian can be found be executing:

./scripts/dependency-manager list --compilation

Runtime

Runtime dependencies for debian can by executing:

./scripts/dependency-manager list --runtime

On a Debian / Ubuntu system, the following command line can be used to install all required packages in one go:

./scripts/dependency-manager install

Building tiscamera

The following commands will build and install our software with default settings.

git clone https://github.com/TheImagingSource/tiscamera.git
cd tiscamera
# only works on Debian based systems like Ubuntu
sudo ./scripts/dependency-manager install
mkdir build
cd build

# With ARAVIS:
cmake -DTCAM_BUILD_ARAVIS=ON ..
# Without ARAVIS
cmake -DTCAM_BUILD_ARAVIS=OFF ..

make
sudo make install

The default installation prefix is /usr. Some components have to be installed in /etc and /lib. If you want to change the prefix, read the section installation directories in our documentation.

cmake options

The most important cmake options are:

• -DTCAM_BUILD_ARAVIS=<ON/OFF> Build tiscamera with support for GigE cameras via aravis.

• -DTCAM_BUILD_TOOLS=<ON/OFF> Build additional tools for camera interaction (e.g. firmware tools and tcam-capture).

• -DTCAM_BUILD_V4L2=<ON/OFF> Build tiscamera with support for USB cameras via UVC/V4L2.

• -DTCAM_BUILD_LIBUSB=<ON/OFF> Build tiscamera with support for USB cameras via LibUsb (i.e. AFU420, AFU050, DFK73).

• -DTCAM_BUILD_DOCUMENTATION=<ON/OFF> Build html user documentation.

• -DCMAKE_INSTALL_PREFIX Installation target prefix (defaults to /usr/)

For a complete overview, read the section cmake options in out documentation.

Optional for GigE-Vision devices: Start the tcam-gige-daemon

GigE-Vision cameras have a several seconds long delay before they can be reliably detected on the network.

To speed up this process for applications, a background daemon is built and installed, which detects cameras before an application starts. The following commands will activate the daemon on your system:

sudo systemctl daemon-reload                 # make systemd aware of gige-daemon
sudo systemctl enable tcam-gige-daemon.service    # start on every boot
sudo systemctl start tcam-gige-daemon.service     # start the actual daemon
sudo systemctl status tcam-gige-daemon.service    # check if statemd say everything is ok

Where to go from here

After installation you can try one of our examples or directly start with a gstreamer pipeline like:

gst-launch-1.0 tcambin ! videoconvert ! ximagesink

alternatively start tcam-capture

tiscamera's Issues

tiscolorize causes GStreamer-crash

I'm currently trying to connect a DFM 42BUC03-ML to a Raspberry Pi. I follwed the Instructions given here and here, as it seems correctly:

root@raspberrypi-Helmut:~/tiscamera/tools/euvccam-fw# ./euvccam-fw -p

But if I now try to access the camera with GStreamer, like suggested in the Wiki, tiscolorize causes a crash:

Missing installation steps

Hello all,

I am trying to install this library for our camera (DBK 72BUC02 [0813]) in a virtualized (virtualbox software) Ubuntu Mint Petra "16" kernel (3.11.0-12 generic), but It can't execute the example (folder examples/gstreamer-0.10/python) gstexample.py.....
I installed all necessary dependencies in my OS and followed the steps from the README.md... (bootstrap.sh, configure. make...).
Finally, when I tried to execute the python script, i got:

Traceback (most recent call last):
File "./gstexample.py", line 167, in
app.create_pipelines()
File "./gstexample.py", line 142, in create_pipelines
% (DEVICE,))
glib.GError: no element "tiscamerasrc"

Furthermore, i had another poblem which should be related. My Ubuntu finds the camera device:
[ 2115.200226] usb 1-2: new full-speed USB device number 5 using ohci-pci
[ 2115.654440] usb 1-2: New USB device found, idVendor=199e, idProduct=8207

[ 2115.654501] usb 1-2: Manufacturer: The Imaging Source Europe GmbH
[ 2115.654509] usb 1-2: SerialNumber: 31310249

But i don't have any "/dev/video*".....
I was checking the code and it seems that there are more steps to configure the O.S (in the folder data seems that there are files to configure some daemon linux...)
I paste my listmod: https://gist.github.com/carlosb1/847475e4096d7e9a68c6

I am confused, i would appreciate any help or some idea to configure this project in my linux..

Neximage 5MP support

Hi,

I am trying to make a Neximage 5MP working on Raspberry PI2.
I was wondering if this camera is supported by your software, if so, which firmware should I use?

Thanks

Sample code in c/cpp for USB2.0 in LINUX?

Could you please tell me where is the sample code for Linux operating system using a 2.0 camera.
OR How can I modify the sample code of GIGE cam so that it works with usb2.0 also.

While I connected two more same camera, /dev/video* lost!!

Hello all,

I have several DMK 42BUC03 camera and I want to grab images by Linux.
I used this sample code on my Lubuntu14.04 (https://gist.github.com/TIS-Edgar/10f04501f49b6b3bf75e),
and everything is fine by using only one camera.
But two question occurred.

Today I want try two same camera and I can find video0&1 at first.
But after I restart my PC, I can't find any /dev/video* !!!
I can find imagingsource camera by
$lsusb
And it returns

Bus 001 Device 002: ID 199e:8208 The Imaging Source Europe GmbH
Bus 001 Device 008: ID 199e:8208 The Imaging Source Europe GmbH

How can I solve this question?

And my second question is:
How I can get capture by using two more same camera(42BUC03).
I tried to change code in main.cpp (open_device((char_)"/dev/video0");), but it can't get two camera capture at the same time before I lost my /dev/video_
Can anyone tell me how can I get several capture by same camera?

thanks all,

VIDIOC_DQBUF error 5, Input/output error

Hello, all

I tried just change
open_device((char*)"/dev/video1");
and make two different opencv-test output to use.
But while I use one named "opencv-test1"(video0), and open another terminal to execute "opencv-test2"(video1), one of them will shut down and return

VIDIOC_DQBUF error 5, Input/output error

How can I get two frames easily and can be used for process.....

thanks a lot

All the best,

Cannot capture images in OpenCV in UVC mode

Hi,

I have a DFK 42AUC03 camera and I want to grab images using OpenCV in Linux. Using euvccam-fw tool, I've updated the firmware to dmk42uc03_143.euvc and switched camera to UVC mode.

guvcview now gives a grayscale video stream in 1280x960. Here is log of running guvcview with --verbose switch: http://textuploader.com/kleq.

I couldn't find a way to get a color image in guvcview. Changing the Camera output to RGB3 caused guvcview to be closed with this error:

libv4l2: error dequeuing buf: Invalid argument
VIDIOC_DQBUF - Unable to dequeue buffer : Invalid argument

Also, I have a problem in capturing image using OpenCV. This simple code which capture image from the camera:

#include <stdio.h>
#include <opencv2/opencv.hpp>
#include <iostream>
using namespace cv;
using namespace std;

int main(int argc, char** argv )
{
    VideoCapture cap(0);
    Mat img;

    if(cap.isOpened())
        cout << "Device opened." << endl;
    else
        cout << "Device not opened." << endl;

    cap >> img;
    if(!img.empty())
    {
        imwrite("frame.bmp",img);
        cout << "Capture success!" << endl;
    }
    else
    {
        cout << "Capture failed." << endl;
    }

    return 0;
}

Gives the following errors:

libv4l2: error setting pixformat: Invalid argument
HIGHGUI ERROR: libv4l unable to ioctl S_FMT
libv4l2: error setting pixformat: Invalid argument
libv4l1: error setting pixformat: Invalid argument
HIGHGUI ERROR: libv4l unable to ioctl VIDIOCSPICT

Device not opened.
Capture failed.

I wonder if I should set some parameters before using VideoCapture object (I have tried settings resolution which didn't help and I couldn't find a way to set the pixel-format).

Getting Aravis example code work for DMK23G274

Hi,

I am trying to get stream from DMK23G274 in C++ code using Aravis library on the ARM board with Ubuntu server. I've downloaded Aravis 0.3.6 from the repository:

https://git.gnome.org/browse/aravis/snapshot/ARAVIS_0_3_6.tar.xz

and after installing various packages, I finally was able to configure, compile and install aravis:

./autogen.sh --enable-gst-0.10-plugin --enable-gst-plugin
make
make install 

The aravis example program now compiles, but running it gives the following error:

gstaravis could not be created.

I tried to capture images using gst-launch tool:

gst-launch-0.10 --gst-plugin-load=/root/ARAVIS_0_3_6/gst-0.10/.libs/libgstaravis-0.4.so aravissrc ! video/x-raw-gray,width=1600,height=1200,framerate=3/1 ! jpegenc ! filesink location=capture1.jpeg

By running this command I get the following output.

Setting pipeline to PAUSED ...

(gst-launch-0.10:30230): GStreamer-CRITICAL **: range start is not smaller than end for `GstIntRange'

(gst-launch-0.10:30230): GStreamer-CRITICAL **: range start is not smaller than end for `GstIntRange'
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock

This commands blocks until so I guess it has connected to the camera. However, the created capture1.jpeg is a zero-length file.

General output Pin in Linux

I would like to know in what way, if possible, I can control the General output Pin of the board monochrome camera? Programatically if possible.

Cannot capture images in OpenCV (DMK 42BUC03)

Hello all,

I have a DMK 42BUC03 camera and I want to grab images using OpenCV in Linux.
I used this sample code on my Lubuntu14.04 (https://gist.github.com/TIS-Edgar/10f04501f49b6b3bf75e), and
$make
these files.

But it returns:

on my terminal...
Can anyone tell me how to solve this question?

I want capture images with my Lubuntu and can use opencv libraries(by C/C++) to process images...

DFM 22BUC03-ML with OpenCV without gstreamer

Hi,

is it posible to get the DFM 22BUC03-ML camera to work with OpenCV under Linux without gstreamer?

I get a picture, but 3 instead of one and I don't know, how to get your gstreamer-modules into OpenCV.

Is it difficult to have tiscamera gstreamer plugin to support GStreamer-1.0 API?

Although not able to have GStreamer-0.10 pipeline working for my "DFx 22BUC03", the GStreamer-1.0 do works. Here's the pipeline:

gst-launch-1.0 v4l2src device=/dev/video1 ! video/x-raw,format=GRAY8,width=744,height=480 ! videoconvert ! xvimagesink

Question:
Is it difficult to have tiscamera gstreamer plugin to support GStreamer-1.0 API?

Release the memory in arvcameratest.c

Hi,

I have a question about the release of the memory in arvcameratest.c of ARAVIS 0_3_3. I modified the program to handle several cameras with one program alternately. This program makes a loop that one camera takes a snapshot with a software trigger and the analysis of the image is done and then it goes to the next camera and do the same procedure. As a start point, I ran the program with only a single camera. Then I found the short of memory after some loops. I inserted system("free") to check how the amount of free memory is decreasing. I found that setting the callback function written in every loop might be suspicious.
l.261 g_signal_connect (stream, "new-buffer", G_CALLBACK (new_buffer_cb), &data);

I guess that unset of the callback function or releasing the memory of "data" is necessary to avoid the problem. If you know anything, could you teach me how to do that?

Incorrect exposure control in DMM 42BUC03-ML

Camera: DMM 42BUC03-ML
Firmware: dmk42uc03_143.euvc

The V4L2 specification gives 1/10000 sec as a base unit for absolute exposure.
See here (V4L2_CID_EXPOSURE_ABSOLUTE):
http://www.linuxtv.org/downloads/legacy/video4linux/API/V4L2_API/spec-single/v4l2.html

It seems it is not implemented this way in the camera. Below are brightness values of an object measured for different exposure settings.
[exposure_absolute] [measured brightness]
1 50
2 68
3 100
4 120
5 150
6 171
7 200
8 225

So 6/10000 (->171) should give twice the brightness of 3/10000 (->100), but this is not the case. It makes more sense, if 1 is in fact 2, 2 is 3, and so forth. Then:
1 -> 2 -> 2/10000 -> 50
3 -> 4 -> 4/10000 -> 100

Is that how it works? In that case, it is not possible to set 1/10000 sec which is the shortest exposure time specified for this camera. My application requires such short exposure times, so I would like to clarify and know what exposure time I am actually using, and I would also like to be able to set 1/10000 sec.

Are all ImagingSource cameras supported?

I'm trying to install a DMK31AU03.AS under Fedora20 (kernel 3.13.6 64bit).
When I plugged it in the device is detected (the following lines are from dmesg):

[ 4.243080] usb 1-5.4.4: new high-speed USB device number 5 using ehci-pci
[ 4.329954] usb 1-5.4.4: New USB device found, idVendor=199e, idProduct=8101

I have successfully compiled and in installed code from tiscamera/src/ and followed instructions from the wiki (https://github.com/TheImagingSource/tiscamera/wiki/Getting-Started-with-USB-Cameras)
But the command
$ sudo ./euvccam-fw -p
failed with the error message
Device not found.
(/dev/video0 doesn't exist).

Are all USB2 ImagingSource cameras supported or we need a specific firmware for DMK31?

Thanks for your help (and for your code!)

Motion blur for short exposure times in DMM 42BUC03-ML

Unfortunately, another problem with this camera, this time a critical one.

We are experiencing a strange problem with light apparently "leaking" into the pixels, which results in kind of motion blur appearing in the case of short exposure times.

Please refer to this dataset: https://drive.google.com/open?id=0B1XDXh7oI3etM08zN1VPdDNOUms

There are three datasets there, each for different exposure time: 1/10000sec, 1/5000sec and 1/500sec. There is also a marked up image.

The camera was being rotated from side to side during the capturing. For 1/10000sec and 1/5000sec, there is motion blur visible on both sides of the circular pattern. The pattern is well exposed, with the exposure consistent with the rest of the frame, while the motion blur is just a ghost. For 1/500sec, this phenomenon is not visible.

It was tested with both the Windows and Linux firmware. Resolution was 1280x960 @15fps.

For reference, we also tried a smartphone camera, which used 1/3000sec and did not show any such problems.

I have the following theory for the mechanism how this happens. The light "leaks" into the pixels outside the desired exposure time. The blur smudge is quite long, so the corresponding time is in the same range as the frame rate (1/15sec). For short exposures, it results in the appearance of the ghost. For longer exposures, the difference in amount of light between the "leaking" and the actual exposure is larger and the ghost does not appear.

There is also another strange behavior, it does not seem to be related to the problem above, but maybe it is an indication of some general problems with the sensor. In some areas of the image, there are dark pixel rows every other row. It is marked up in the image in the dataset.

As the camera can experience such quick movements in our application and short exposure times are necessary, this problem renders the camera inadequate for our application at this time. I would appreciate a quick response, as we will need to make a decision whether there is a resolution here or we need to move on and try another product, which would be disappointing.

Thanks,

Tom

When attempting to use this camera with guvcview the program's trigger checkbox is ignored by the camera, hence cannot use triggering with this camera.

The camera is DFK 22BUC03 running on Raspberry Pi B+. Calling v4l2-ctl --all shows that the camera supports trigger (bool), trigger_global_reset_shutter (bool), and privacy (bool).

Snap image with Gig-E camera

Dear all,

Now I and my colleague are trying to simply snap the image with the camera DMK 23GM021, employing Gigabit-ethernet communication (Product of Imaging Source company).
We have used arvcameratest.c and related libraries provided athttps://github.com/TheImagingSource/tiscamera/wiki/Aravis.
However, this program seems to capture an image as one shot in the video. This is different from what we want. We want to simply capture an image at an arbitrary time and take images a few times with a short interval (~10ms). The video mode takes a longer dead time (~500ms) than the time we want to achieve. We also want to make a loop of the process using several cameras, i.e., taking an image one after another with different cameras. So we are afraid that the memory buffer is saturated if the video mode is used because we need a few images and others are stored in the buffer.

If you know how to take a snap shot and shorten the dead time or have any suggestions, could you teach us?

We really need your help.

Best regards,

focus_absolute

Hello,

I'd like to know what the variable focus_absolute is for. I tried to change the value but nothing seems to happen.

The camera model is dfk72buc02.

thanks

Forcing DHCP state with camera-ip-conf

Hello,

I'm having problems with the DHCP configuration of a DMK23G445. The camera is connected to a switch, the switch is connected to a ADSL box. No subnets are configured, I'm expecting that when the network goes up after a cut-off (the network is not very reliable... :( ) the camera will ask the box DNS for an IP address in the correct range (192.168.X.X). This is not the case: the camera obtain a strange address (169.254.X.X DHCP server is not found?).
camera-ip-conf-cli info tell me that DHCP is off and Current Gateway is 0.0.0.0
Using camera-ip-conf-cli allowed me to force dhcp and gateway only if the IP address is specified.
For the project I'm involved in, soon, the number of cameras I will manage will increase and fixing the IP address for each camera avoiding superposition with local network is not easy in an automatic way.
Do you think it could be possible (and interesting for you) to just force the gateway and DHCP use with camera-ip-conf-cli?
Thanks for listening,
Chiara

USB3 UVC Extensions Fail to Import

I'm reporting this as an issue because import XML and installation instructions come from this code repository.

My USB3 model, DFK 23UM021, camera is not setting up correctly. I can install the udev rules fine following these instructions: https://github.com/TheImagingSource/tiscamera/wiki/UDEV-Rules. However, when I try to install the uvc extensions, I receive a flood of errors. I'm working on a Debian Jessie machine. I'm following the instructions as noted here: https://github.com/TheImagingSource/tiscamera/wiki/UVC-Extension-Units . Every single extension produces a "error 2: No such file or directory" message.

I am using a fairly new kernel version:

Does DFK21BU04 camera support trigger and exporsure function?

hello?

i'm trying to make an application which take a snap shot triggered by external signal.

i'm using a respberry pi and DFK21BU04.

trigger and exporsure function are required.

bellow shows the functions that it support.

however there are no trigger function and exporsure function.

are there no way to make my application except buying a new camera?

Not complete frames with v4l2 and opencv

Hello,

I have a DMK Camera (DMx 31AU03.AS) that I would like to control under linux (Debian). I have tried your code example https://gist.github.com/TIS-Edgar/10f04501f49b6b3bf75e but I don't understand why the grabbed frames are not complete. I have tried to change the FPS value but it changes nothing to the result. Here is what I always get :

Do you have an idea of the problem ?

Thank you very much !

DFK 22BUC03 as camera node in ROS

Hello!

I'm trying to use TIS camera as camera node in ROS with usb_cam package.

Here is standard launch file cam.launch:

<launch>
  <node name="camera" pkg="usb_cam" type="usb_cam_node" output="screen" >
    <param name="video_device" value="/dev/video0" />
    <param name="image_width" value="640" />
    <param name="image_height" value="480" />
    <param name="pixel_format" value="mjpeg" />
    <param name="io_method" value="mmap"/>
  </node>
</launch> 

Camera node is not starting after "roslaunch cam.launch".
Other usb camera work in this case well.

But if I change

<param name="io_method" value="usr"/> 

instead of mmap (just for checking) - camera node start but the image is very bad (triple image with bad color representation instead of mono).

How I could run the camera for ROS in my case?

@TIS-Stefan Do you have some C sample code Not c++ to get video stream?

@TIS-Stefan
I am using DFM 72BUC02-ML in ubuntu 14.04. I find here from google
I have asked technical supporter to update the firmware with dmk72uc02_162_uvc.euvct.
Now I can get color pictures using the code you posted before at here: https://gist.github.com/10f04501f49b6b3bf75e but there is a problem: the color is not correct,for example, orange become blue ... I think Maybe I need change some parameters to adjust it in the code, so It 's not a big problem?

I have another important question: Do you have some C sample code Not c++ to get video stream? if you have not ,Do I need write it from V4L2 for my company embedded device(not need GUI to display the Live image,only get the data to memory or save the picture to jpg files)?

Compatibility With GStreamer-1.0

Is the element tiswhitebalance available with Gstreamer-1.0 ?

Returned the firmware to factory defaults, now it only displays in grayscale

hello, I used the firmware update tool with a DFK 72BUC02 and it worked nice in linux but in grayscale, when I returned the firmware to factory defaults to work on Windows again, it keeps working on grayscale, so, how do I change this in Windows? I am trying to make a stereo pair and one takes the image in color and the other one in grayscale, so how can I set up both in color or in grayspace? with IC capture I use the debayering but can I activate it and deactivate it without IC capture? thanks

How to enable external trigger?

My TIS camera has a external trigger input.
It is working under "Free running" mode.
Is it possible to switch to "Trigger" mode in Linux?

Thanks in advance,

Issues with capture monochromatic images using openCV

Hi Edgar,

I'm trying to capture gray scale images from an Imaging Source monochromactic camera (DMK 23UU45) in linux using openCV through the Python interface cv2 (v 2.4.8).

I am able to initialize the camera capture class via cv2.VideoCapture; however, the only properties that are currently recognized are the images size and width:

cam1 = cv2.VideoCapture(1)
cam1.get(3)
1280.0
cam1.get(4)
960.0

If I try to get the status of other properties I get an error:

cam1.get(1)
HIGHGUI ERROR: V4L2: Unable to get property (16) - Invalid argument
-1.0

The image that I am getting is three copies of the original image not a full resolution:

Not sure if it is of consequence, but when I initialize an instance of the VideoCapture class for the camera I get the following:

libv4l2: error set_fmt gave us a different result then try_fmt!
HIGHGUI ERROR: libv4l unable convert to requested pixfmt
libv4l2: error set_fmt gave us a different result then try_fmt!

Any help you can provide would be greatly appreciated.

Thanks,
Eric

GStreamer-0.10 pipeline with tiscolorize and bayer2rgb fails

The pipeline without tiscolorize and bayer2rgb may live longer before hitting ERROR:

gst-launch-0.10 --gst-debug-no-color --gst-debug-level=3
v4l2src device=/dev/videoTIS1 !
video/x-raw-gray,width=744,height=480 !
ffmpegcolorspace ! xvimagesink

The pipeline with tiscolorize and bayer2rgb fails within 15 seconds:

gst-launch-0.10 --gst-debug-no-color --gst-debug-level=3
v4l2src device=/dev/video1 !
tiscolorize ! tiswhitebalance ! bayer2rgb !
ffmpegcolorspace ! xvimagesink

First of all this is now a different problem. Somewhere in the pipeline something begins to choke.

1. Can you enable --gst-debug-level=3 again? We need a more general overview this time.
   It is attached to the tail of this message. Please advise.
2. Does this error occur all the time?
   Yes, sometime it occurs after 9 seconds, the other time it occurs after 12 seconds. But, it always occurs.
3. Does reattaching the camera cause changes?
   No, the error still happens.
4. Does this error occur even when going over /dev/videoX ? Just to be sure, that there is no catch with the symlink.
   The attached message is with /dev/video1

Getting "VIDIOC_DQBUF error, Invalid Argument" on Linux kernel 3.0.36+

Hi,

I get this error on kernel 3.0.36+:

VIDIOC_DQBUF error 22, Invalid Argument

when I run the following example code (provided by @TIS-Edgar at #11) for capturing images:

https://gist.github.com/10f04501f49b6b3bf75e

After debugging, apparently at the line 109 of v4ldevice.cpp (inside read_frame function) this error occurs.

I checked capturing video of a webcam using guvcview and it didn't any this problem.

How to force change RGB to GRAY?

Hello all,
I have a DMK 42BUC03 camera and I want to change its RGB data to GRAY.

cvCvtColor(pOpenCVImage,pColorCVImage,CV_BayerGB2RGB); // Create a color image from the raw data

Can I just change parameter in this function or I should grab picture first and change RGB to GRAY..
Hope I can get GRAY pics to process as real time.

How to use gevCapture.c

Hi,

I would like to ask you how to use gevCapture.c. There seems not to be a description about this. What I want to do is just taking a snap shot with software trigger. How should I do?
Referring to the brief explanation shown by --help option, I executed "./gevCapture -c test_kt0 -w 1280 -h 960 -e 3000 -g 1 -f 1 -n test1 -s -o 1" and press "g" but the message "saving stream!" appeared. The product is RAW file. So I'm not sure how to check if the snapshot was taken.

I also found the following errors when executing the command "gevCapture" with any options. But actually I can see the movie with "MPlayer". Is it critical to run the program? I ran this program on Ubuntu 12.04 LTS.

%./gevCapture -c test_kt0 -w 1280 -h 960 -e 3000 -g 1 -f 1 -n test1 -s -o 1

USB Color CMOS DFK AFU050-L.34: Device not found!

Hi! I'm trying to install a DFK AFU050-L.34 under Manjaro x64 or Debian Jessie x86.

When I plugged it in the device is detected (the following lines are from dmesg):
[ 1314.428152] usb 1-3: new high-speed USB device number 4 using ehci-pci

I have successfully compiled and in installed code from tiscamera/src/ and followed instructions from the wiki (https://github.com/TheImagingSource/tiscamera/wiki/Getting-Started-with-USB-Cameras)
But the command
$ sudo ./euvccam-fw -p
failed with the error message
Device not found.

Also /dev/video0 doesn't exist.

As this is a CMOS camera I understand I don't need the udev rules, anyway I have tried without success.

What I'm missing? Thanks for your help!

Hot Pixel Correction

Use Software trigger

Hello,

I have some troubles to use aravis software trigger with long exposure time on a DMK23G445 and a Basler ace1300gm. I would like to capture single images on the both cameras with the maximum available exposure time.

On the DMK, the maximum exposure time is 30 seconds.
With the Basler, it's 10 seconds.

For now, I can grab single image with 10 seconds exposure time on the basler only if I use sleep(1) before to emit a software trigger and I don't understand why I need to wait 1 second. It doesn't works with the DMK if I wait 1 second before to emit the software trigger. If I don't wait before to send software trigger, I can only grab single frames if the maximum exposure time is 5 seconds. If I set the exposure time to >5, 10, 20, 30, it doesn't work.

I am doing the following things in my program :

• set gain, exposure, fps (the minimum for the DMK is 3.75), format ...
• create a stream with arv_camera_create_stream() and the following parameters :
  ARV_GV_STREAM_PACKET_RESEND_NEVER
  ARV_GV_STREAM_SOCKET_BUFFER_AUTO
  packet-timeout = 40000
  frame-retention = 200000
• push a new arvbuffer in the stream with arv_stream_push_buffer()
• set acquisition more to continuous with ARV_ACQUISITION_MODE_CONTINUOUS
• configure camera to use software trigger with arv_camera_set_trigger(camera, "Software")
• start acquisition with arv_camera_start_acquisition(camera)
• sleep(1) if I use the basler camera
• send software trigger with arv_camera_software_trigger(camera)
• get the arvbuffer from the stream with arv_stream_timeout_pop_buffer(stream, exposuretimevalue (us) + 1sec)

I don't understand what's wrong and why I can't get a complete buffer from the stream.
If you are familiar with aravis or software triggers, could you give me some hints please ?

If I use ARV_ACQUISITION_MODE_SINGLE_FRAME instead of ARV_ACQUISITION_MODE_CONTINUOUS, I can grab frame with 30 seconds of exposure time on my DMK and with 10 seconds on my Basler but I would like to use software trigger.

Thank you very much !

How to use ARV_ACQUISITION_MODE_SINGLE_FRAME?

Dear all,

I still try to take a snapshot using the software trigger. Then I found that ARV_ACQUISITION_MODE_CONTINUOUS and ARV_ACQUISITION_MODE_SINGLE_FRAME in src/arvenums.h of ARAVIS_03_03. In tests/arvcameratest.c, ARV_ACQUISITION_MODE_CONTINUOUS is used. So I guess I can take a snapshot with the software trigger if I replace it with ARV_ACQUISITION_MODE_SINGLE_FRAME. But I don't know how to modify arvcameratest.c accordingly.

If you know how to modify or good examples using ARV_ACQUISITION_MODE_SINGLE_FRAME, could you teach me?

Best regards

How to change camera serial number?

How can I set ROI (DMK 42BUC03)

Hello all,

Can I set ROI (by Opencv or its hardware) not only supported on website.
For example:

ImageSize.width = 1280;
ImageSize.height = 300;

While I change this on my main.cpp, I can't view correct image.
Can anyone tell me how to change image's ROI by myself?
Prefer the fastest way but not use waste CPU speed. (hardware? Opencv?)

thanks all,
ccrb
