[rosrun] Couldn't find executable named dataset_slam below /home/roshnee/catkin_ws/src/lsd_slam/lsd_slam_core

[Roshnee]

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?

You need to use "dataset" instead of "dataset_slam" in 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. But do tell me if you got it working for reading RGM image files in a folder. I am getting this error terminate called after throwing an instance of 'ros::InvalidNameException' what(): Character [0] is not valid as the first character in Graph Resource Name [0]. Valid characters are a-z, A-Z, / and in some cases ~. Aborted (core dumped)
