LSD SLAM Not working...
Good day I'm new to LSD SLAM and I am looking to use it on a 100 images. I am running on a Ubuntu 14.04 machine, and using ROS Ind My operation runs as follows: I open my 1st terminal : roscore ....2nd terminal: rosrun lsd_slam_viewer viewer: point cloud window pops up .....3rd terminal: I go on to enter the following command:
rosrun lsd_slam_core dataset_slam _files:=home/rick/Mokolo/lsd-test/images _hz:=0_calib:=/home/rick/rosbuild_ws/package_dir/lsd_slam/lsd_slam_core/calib/OpenCV_example_calib.cfg
I then get the following output:
Reading Calibration from file /home/rick/rosbuild_ws/package_dir/lsd_slam/lsd_slam_core/calib/OpenCV_example_calib.cfg ... found! found OpenCV camera model, building rectifier.

Should I try out a different calibration setting or is the problem not that?
Or is the problem the fact that it cannot load a file list due to a wrong path?
I also have same issue. 1st terminal : roscore --> okay 2nd terminal: rosrun lsd_slam_viewer viewer: point cloud window pops up --> with black window 3rd terminal: I go on to enter the following command: ubuntu@ubuntu:~/rosbuild_ws/package_dir$ rosrun lsd_slam_core live_slam image:=/image_raw camera_info:=/camera_info --> [rosrun] Couldn't find executable named live_slam below /home/ubuntu/rosbuild_ws/package_dir/lsd_slam/lsd_slam_core
@sophie-shin run the 3rd terminal command in ~/rosbuild_ws/package_dir/lsd_slam/lsd_slam_core/bin directory
@sakshamgupta006 i am facing the same problem. I followed your instruction, but still it is showing the same error.
Did anybody here get it working coz even im having the same issue
