After run the Project I get an error: libusb-1.0 development package not found

I would like to get the Thermal stream as deep learning model input.
What is the best way to get the Thermal stream?

Hello,

I downloaded the binary file for Mac Os, opened GetThermal; however, I am not seeing an image. I verified that I could see an image on a windows machine so I am sure the that the Lepton 3.5 is seated properly. Also on the Mac OS, if you look at the camera Info it is showing the wrong device (Pure Thermal 1 vs. what I have is a PureThermal2). But if I look at the usb connection in Mac OS it shows the right device and firmware. What could be preventing me from viewing imagery on the Mac?

Hello,
Does UsbWebCameraPro work for anyone? Is there any other app that works?
Br,

I'm running the GetThermal App on my Rasberry PI 3 B+. It all works fine, but after a while the image freezes. The command line keeps on outputting: -9UVC_GetAttribute failed
I'm using the Purethermal2 board with a FLIR Lepton 2.5

The GetThermal AppImage is not running on Ubuntu trusty, possibly it was built on a build host that was newer than Ubuntu trusty, which pulls in "too recent" dependencies on core system libraries such as libstdc++.

Error log:
https://travis-ci.org/AppImage/appimage.github.io/builds/287151543#L713-L728

Would it be possible to build the AppImage on Ubuntu trusty or earlier?

Hi I am trying to install GetThermal in Ubuntu 18.04. I installed everything but the make command for .../GetThermal/build is throwing following error. I could not find any solution for it.

/usr/bin/ld: cannot find -lGL
collect2: error: ld returned 1 exit status
Makefile:274: recipe for target 'release/GetThermal' failed
make: *** [release/GetThermal] Error 1

Any kind of suggestions / references will be helpful to me.
Thank you.

I have been trying to use this with the PureThermal mini, I know that it doesn't specify compatibility with this version of the PureThermal board. But I thought it may anyway because they're both made by GroupGets.

Hello,

I built GetThermal for NVIDIA TX2, running Ubuntu 16.04(x64) and Qt 5.9.5.
When start as a normal account, it cannot display video.
But as a sudo, it cannot show gage.

I attach screenshots as follow, and wait for any helpful advice.
Thanks,

I've followed all the instructions for building GetThermal with a Raspberry Pi and the GetThermal window opens.

However, the thermal image is missing when I do so. I've probably missed something simple, but was wondering if you have any advice?

I run the code in my rasperrypi, but i do not need the GUI, I only wannd get the temperature .I want to read the temperature on the image through usb. What should I do? Thank you

Bellow is SeekThermal UDEV config rules. What is Purthurmal2 with lepton3.5?

Hi,

great work ported and run also on Jetson NVidia TX1.
not sure I understand your comment on Getthermal.pro - radiomentry of boson:
Radiometry on Boson isn't obvious, switch to hw color mode and suppor…

what do you mean? how to switch to hw color? if so why did not force it in the code :)
is it a sort of mimic radiometry with boson?

thanks
mm

Hi, I noticed you are using AppImageAssistant. It has been replaced by appimagetool. Overall an approach using Travis CI and then bundling the build artifacts like in these examples (using functions.sh which abstracts away all the hard work) seems easiest to me.

When you use generate_type2_appimageinstead of generate_appimage, then appimagetool is automatically used in the process.

For Qt applications, linuxdeployqt might also be worth a try. These projects are already using Travis CI and linuxdeployqt to provide AppImages of their builds:

• https://github.com/Blinkinlabs/PatternPaint
• https://github.com/fathomssen/redtimer
• https://github.com/coryo/amphetype2
• https://github.com/chkmue/MyQtTravisTemplateProject

Hi all,

I'm using a lepton 2.0, the pt2 and an ubuntu laptop.

I successfully compiled GetThermal after a lot of issues and missing dependencies with qt. When I open the device using VLC it does work and I can see the thermal image from /dev/video1, but when I execute:

sudo ./GetThermal

I see the next screen:

The output in the terminal is:

I'm not sure if its a problem of a missing qt dependency or a problem with the compilation or with my camera...

I want to see the temperature in thermal image.

But I use purethermal(v1.3.0) & lepton 3.5. It only show thermal image without most right side bar which shows temperature.
Is there any way to make GetThermal to show temperature?

Hey everyone,

Maybe this is very easy, so I better start with an apology, because I just started recently being a programmer and I'm especially new to C++ :)

I really love the program and I want to make some experiments with it. So as the topic says, I try to disable the video output, so I can use it on an Ubuntu Server via SSH. If I try to run the program right now, it says "Could not connect to any X display.".

I tried to solve the problem, by removing/commenting the lines related to the uvcvideoproducer in the main.cpp and compiling it again, but it's still looking for a display and doesn't start via SSH. I really don't know where to continue from here in order to solve the issue I'm having.

Thanks a lot, in advance for any help! It's very appreciated!

I use ubuntu os , the GetThermal Video Image Freeze sometimes , I close the window , Type c into PC USB again , open the software , it works. I shake the lepton board also freeze .

i sweeps through the input's height (y direction) and j its width (x)

values passed to setX() and setY() should then be inverted

Thanks!

Hi I was wondering if it is possible to use this app to live stream the camera to FB or Youtube?

Thanks

Nick

There was a change to the usb hardware on the Raspberry Pi 4, so it now uses a VL805 host controller and communicates via PCIe (see here). Despite my hopes that this would solve the current issue with using the PureThermal 2 on a RPi, this seems to have broken the current method for accessing stream data all together.

Here is error printout:

Estimated / selected altsetting bandwith : 18 / 962. 
start_streaming: Unknown error (-99)
Device closed
Segmentation fault

It looks like GetThermal is able to locate and identify the device, it only crashes on start_streaming(). Has anyone else encountered this issue?

Hi,
I have successfully built the Getthermal project in Jetson nano and observed the output is there.
Thanks for the great project.

My hardware is Jetson nano with Lepton3.0 sensor with purethermal2 breakout board.

Although i can see the video stream output is there but no temperature readings on GUI.
I understand purethermal2 board is generally recommended to be used with Lepton3.5 but is there any way/workaround to get the temperature readings with Lepton3.0 sensor? as i have Lepton3.0 and want to use purethermal board for USB interface.

I have also tested "https://github.com/groupgets/purethermal1-uvc-capture" and it also ran well but there temperature readings are way too off.
Any help in that also be appreciated.

Just for additional information-
I check the following link-
https://github.com/Myzhar/Lepton3_Jetson
This is based on GPIO based breakout with lepton3.0 sensor with jetson nano.
I can successfully see the decent calibrated temperature output also.

Let me know if any information is required from my end.
Thanks.

My PC is running Windows, not Linux. Please compile a Windows version for me. I'm considering buying the FLIR 3.5 with a USB interface board, and I need Windows software to use it. I won't buy it if I can't use it.

Hi all,
I first tried on Windows 10 and I have the same issue as @nomad described here:
https://groups.google.com/g/flir-lepton/c/NnLDO1Ua4ss
Camera is visible in both CCI and Camera Feed selection, LED is lit constantly and shutter closes for a second periodically,
but there is no image, just grey square in the middle.

So I tired with Linux Ubuntu 20.04, I follow steps that are described in Readme file.
Everything goes through without any errors. I run:
sudo ./GetThermal - That is located in /GetThermal/build/release and this window opens:

Theres is no image, GetThermal returns onto terminal:

I also tried running GetThermal.pro with QT, which opens similar screen:

It seems like resolution might be the problem, which is 160x120 for Lepton 3.5 and software expects 80x60.
I have check the cable with a mobile phone and I am able to transfer data via it.

There have been several issues dealing with bugs related to the Raspberry Pi 4 including #29 and #23 . The wiki instructions have not been updated to reflect this. There seem to be specific steps that need to be taken such as building a non-master branch or applying a patch. These instructions should be incorporated into the wiki instructions.

Hello Guys

Thanks for your Git in advance.
But, does anybody know if this works for USB C-Thermal Cams? For example the Infiray P2?

I follow the installation guide on my Mac running Monterey. However, when I get to the last step, running make in the created build folder after running qmake, I get the following message at the end:

23 warnings and 3 errors generated.
make: *** [obj/LEPTON_SDK.o] Error 1

Wondering what's causing this, and how it can be resolved, because when I try to open the GetThermal app, I get the following error:

You can’t open the application “GetThermal” because it may be damaged or incomplete.

Any help is appreciated!

Thanks.

I'm using a Lepton 3.5 with a PureThermal mini pro JST-SR board, MacOS 10.14 AMD chip.
When I try to boot into DFU mode (as described here), the light turns off completely, and I'm unable to get my Mac to recognize the device. Before entering boot mode, the light blinks on and off.

I'm at a loss for trying to get any code onto this board, since I can't get my computer to recognize the device. Any advice at all is welcome.

I had, as some users before, bigger problems with the software complaining about access rights.
I am using
Linux Mint 4.15.0-50-generic #54-Ubuntu SMP x86_64 GNU/Linux
with Purethermal2 connected to the PC via an USB hub.

Finally I connected the Lepton 2.5 / Purethermal2 directly to the PCs USB port w/o an USB hub and suddenly it works.

PS: binary isnt working either

I am trying to get a Lepton 3.5 on the PureThermal 2 - FLIR Lepton Smart I/O Module to simply take a picture so I can test it out this weekend in the field. Earlier today I tried to get the pylepton module to work but once I finally got opencv to work the example code does not seem to capture an image. So I thought if I could get the GetThermal software to work I could at least take an image then I would figure out the python module later but this is not working either. I can get all the way to the last step of Build getthermal then when I run make I get the error below.

hello!
how are you?
is there a simple way to create a rtmp stream with this device?

I have a PureThermal 2 with Lepton 3.5. Windows 10 VLC play the video stream, on Ubuntu 18.04 VLC can't play, the log show "v4l2 stream error: cannot open device '/dev/video0': Operation not permitted" and "audit: type=1400 audit(1553403072.607:47): apparmor="DENIED" operation="ptrace" profile="snap.v

Permision of /dev/video0 und /dev/bus/usb... is set to my username.

I have Lepton 3.5 + PT1 Board and want to work in Windows.

Have anybody a SW for windows?
Thanks for help

Hi there,

I tested my Lepton Flir 3.5mm with the soft get Thermal and I cannot reach the dynamic range that was advertised by the manufacturer.
Indeed, this camera should be able to detect temperatures up to 400°C but the limit of the visualisation with this software in both high and low gain is of 181.35°C.
I just want to now if this issue is due to the software or to the camera that cannot transmit a higher level of intensity via the board.

Have a nice day,
Maxime B.

The Programm wont start and freezes.

Hello,

I am trying to use GetThermal on OpenSUSE 42.3. I have QT 5.11.1 installed and I am able to get the application to run, however, I am running Linux through Virtual Box. GetThermal builds correctly and reads the camera successfully but, no image is seen in the application. In the application output it reads, "uvc_open: Access denied (-3)".

Any help to solve this issue is appreciated. I have run qtcreator using the sudo command in the terminal but, it reports some text and is then aborted. I have also tried to run Virtual Box as an administrator on the computer I'm using and that has not helped. I have attached a screenshot of qtcreator and GetThermal as I was running Virtal Box using 'Run as Administrator'.

Thanks,
Jessie A

Running Armbian on TinkerBoard S. Everything compiled fine
UVC device (Lepton 3.5) is found: Using GroupGets PureThermal (fw:v1.3.0) with firmware 00040014-5110-3538-3731-313200000000
Temperature values in SpotInfo also respond correctly but I get not image in the viewer.

Has anyone run into this issue before? Would it be possible it has something to do with the gstreamer1.0-plugins-[..] packages?

Note at startup I can get an image on VLC. After I have run GetThermal though, I can no longer open the capture preview on the same /dev/videoX (orange "waiting"bar moving back and forth). lsusb still shows ID 1e4e:0100 Cubeternet WebCam

Thank you so much!

Hej Guys,

thank you for all the supplied software.

when running GetThermal without root privileges my Q'T Creator Application Output states:
uvc_open: Access denied (-3)

I can launch sudo ~/GetThermal/build/release/GetThermal after manual build sucessfully, but would like not to do this by hand every time and waive on sudo.

I tried to sudo chown $USER:$USER /dev/usb/dev/002/002 to grant access to normal user on the usb device, but still no relieve.

Regards,
Jarvis

OS: Manjaro on x86_64
(as well on Ubuntu 18.04 on x86_64)

EDIT:
i chown'd the wrong device - works now

We're running VBox with openSuse 42 and we're unable to get an image from our Pure Thermal 2 camera with a Lepton 3.5 chip.

This is a screenshot of the console and terminal attempts to run the program. As you can see from the terminal we are getting a message saying, "No such device (-4)". We're running as sudo.

hello!

I would like a color graph.
i have a problem like the picture. Please tell me how to fix it

Good afternoon when, trying too run the app in QT Created, getting the following error.

QQmlApplicationEngine failed to load component
qrc:/main.qml:11 Type Viewer unavailable
qrc:/Viewer.qml:2 module "QtMultimedia" is not installed

Please advise

On Lepton 2.5 and 3.5 devices users should be able to add measurement points to defined locations on the image. tCam has this functionality but unfortunately it does not support PureThermal boards.

Hello, I am using Lepton 3.0 with GetThermal on Ubuntu. Camera is correctly working as UVC when tested via browser on https://davidwalsh.name/demo/camera.php

I have that on both latest releases: GetThermal-v0.1.3-x86_64-Linux.AppImageand GetThermal-v0.1.4-x86_64-Linux.AppImage

• Will radiometric scale even work on Leptopn 3.0, and what firmware do I need for this?

Hi all,

Am not getting any video feed from the Lepton although the app is running. Please advise.
