Couldn't find executable named viewer #156

Open Linusnie opened 8 years ago

Linusnie commented 8 years ago

Hello! I came across lsd_slam during a project and want to try it out, but I've run into a problem.

When I try to run the viewer using rosrun lsd_slam_viewer ROS returns: [rosrun] Couldn't find executable named viewer below /opt/ros/indigo/share/lsd_slam/lsd_slam_viewer Any ideas on what might be wrong? I followed the installation procedure as in the README.

My lsd_slam_viewer folder is identical to the one in this git repository. I'm using ROS indigo on Ubuntu 14.04.3.

lsd_slam shouldn't be found in your /opt/ros/ directory it should be in your catkin workspace. If you already have it in a workspace (probably in /home/[username]/my_proj or similar) make sure you have successfully compiled it and have sourced the setup.bash file

Thanks for the help! It turned out I had managed to skip installing one of the packages listed in 2.2 in the README (I also didn't realize I needed to have roscore running). I've managed to get the minimal setup to work now.

I would like to try out live_slam using my laptop camera. Is that possible? In that case how do I find out what yourstreamtopicand yourcamera_infotopic are supposed to be in rosrun lsd_slam_core live_slam /image:=<yourstreamtopic> /camera_info:=<yourcamera_infotopic>?

I'm very new to ROS, any pointers on where to look would be helpful

Dear @Linusnie , I stuck in the same. After reading your comment, I opened roscore in another terminal, and re-installed every package. But the problem persists. Please describe your troubleshooting in more details. LSD-SLAM is a very popular visual SLAM and I'm trying to apply it to a self driving car challenge. Any help would be much appreciated.

@TungTNguyen @Linusnie I ran into the same problem. But I I didn't skip installing any packages and rosmake seemed to be working fine. But still got the issue and indeed there is no executable named viewer below lsd_slam_viewer. Any suggestions would be appreciated.

This issue is probably because the package.xml file and the cmake file is not configured properly. Go through the detailed tutorial once for the installation. I faced the same problem and now it is solved.
