Omnidirectional Cameras
Hi everybody,
Please, somebody knows how to use this implementation with omnidirectional cameras? It seems the same author publish the paper for that, but I am not sure if this lsd salm implementation works for that images.
In advance, thank you so much for any information about that.
SLAM to work with TUM RGB .bag files
I have got LSD SLAM working with "Quickstart / Minimal Setup" on Ubuntu 16.04 and ROS Kinetic. But when i run .bag file from TUM RGB dataset nothing happens. Point cloud viewer is not showing anything and Debug Depth window also doesnt pops up. I am using calibration parameters from TUM site. On running rosrun lsd_slam_core live_slam image:=/image_raw _calib:=/home/maq/catkin_ws/src/lsd_slam/lsd_slam_core/calib/calibration_params... I get this on terminal
`Reading Calibration from file /home/maq/catkin_ws/src/lsd_slam/lsd_slam_core/calib/calibration_params ... found!
found ATAN camera model, building rectifier.
Input resolution: 640 480

Prepped Warp matrices

And after this rosbag play ~/MAQ/rgbd_dataset_freiburg3_long_office_household.bag file starts playing but no result on PointCloud Viewer or Debug Depth Window.
make failed in ubuntu 16.04 ros-k with jetson tx2
the first exception said: 'error: __m128 was not declared in this scope'
jetson is arm64 architecture so I wonder if some where need to be modified.
live_slam window doesnt pup up. Not showing the window with color-coded depth (from live_slam).
Hi
I successfully installed the lsd_slam on my Buntu16.04 and ROS kinetic. Im able to see the window from the viewer showing the 3D map , But when rosrun lsd_slam_core live_slam image:=/age_raw camera_info:=/camera_info I got this
WAITING for ROS camera calibration!
Received ROS Camera Calibration: fx: 254.326950, fy: 375.934387, cx: 267.381897, cy: 231.599091 @ 640x480
RECEIVED ROS camera calibration!
Started mapping thread!
Started constraint search thread!

Then nothing show up. No window pups up I followed the issues and solutions here
tum-vision#222 and here
But nothing help
Any help?
Displaying depth map
Heya,
has a solution been found for displaying the depth map?
I am getting the following output which seems to be the same for most people in the tum_vision version
QObject::killTimer: Timers cannot be stopped from another thread
QObject::startTimer: Timers cannot be started from another thread
^CQObject::~QObject: Timers cannot be stopped from another thread
I followed the instructions on your Wiki
Thanks
Can't build since Qt is unsuitable
Hello.
I've tried to build this repo using catkin build and met some errors that "QObject No such file or directory". I've double checked what is going on in CMake and tried to run cmake separately inside lsd_slam_viewer folder and here is what i've got

So, my qt 5.12.8 is unsuitable for some reason and of course it haven't been found and used so i can't just make this project.
Here is the CMakeLists with minor changes.

Master/ catkin workspace
In which workspace do i have to run the slam. Master or catkin branch?
Segmentation fault (core dumped) when running lsdc_slam node
I followed the instruction for installation and compiling this package on ubuntu 16 and ROS Kinetic, it compiled successfully but upon running the slam node, I get segmentation fault. I am wondering what the problem can be.
Thanks!

[rospack] Error: package 'lsd_slam_core' not found
Viewer's pointcloud is 2d
Hi,
when I run LSD-SLAM I only get a 2D plain as "pointcloud" in my viewer window.
When running an example bag file it gets 3D but when trying my own camera it is this kind of flat thing.
Any idea what I'm missing?
main_on_images is almost 300x slower than main_live_odometry
When I run live_slam the odometry pose updates at a fast rate (~30Hz). The input is my laptop's webcam (Calibrated) with input configured to be 640_480 (no cropping).
Afterwards, I compiled main_on_images and fed it with sequence_30 images. The calibration file uses crop setting and same image size 640_480 (cropped). The frequency of pose update (from Output3DWrapper) is about 0.1 Hz (about 10 seconds or more for one pose output).
I have used the same CMake settings to build the executable as used by catkin. I want to speed up the processing (as fast as the main_live_odometry version. Any help is appreciated.
[rosrun] Couldn't find executable named dataset_slam below /home/roshnee/catkin_ws/src/lsd_slam/lsd_slam_core
I did install all the required dependencies and i traced back to the folder catkin_ws and ran catkin_make. i also ran the command roscore in the other terminal and performed a rosrun for the lsd_slam
rosrun lsd_slam_core dataset_slam _files:=/home/roshnee/catkin_ws/src/T1_rectified/images _hz:=0 _calib:=/home/roshnee/catkin_ws/src/T1_rectified/calibration.yaml
and this is wat i get
[rosrun] Couldn't find executable named dataset_slam below /home/roshnee/catkin_ws/src/lsd_slam/lsd_slam_core
Can anybody help me pls?
Linking error
I'm on Ubuntu 16.04, and ROS-Kinetic. Following the steps given in wiki, I end up with following linking error :
/home/vivek/ros_files/catkin_ws/devel/lib/liblsdslam.so: undefined reference to 'g2o::OptimizationAlgorithmLevenberg::OptimizationAlgorithmLevenberg(g2o::Solver*)'
The solver mentioned in the error log : OptimizationAlgorithmLevenberg(g2o::Solver*) Is being used in KeyFrameGraph.cc (reproduced below)

Nothing is displayed in PointcloudViewer.
Hello. I follow your instruction for installing LSD-SLAM with ROS Kinetic.
Install for LSD-SLAM is perfect with no error. But, when I run lsd-slam with default rosbag play LSD_room.bag, I can't see anything in PointCloudViewer.
This is my commands:
- rosrun lsd_slam_viewer viewer (work fine)
- rosrun lsd_slam_core live_slam /image:=/cama/image_raw camera_info:=/camera_info
- rosbag play LSD_room.bag
I also saw your Usage for lsd-slam. first, cv_camera_node is executing webcam node. second, execute lsd slam core.
What part is wrong in my commands? How can I see point cloud data?
