"No cam calibration" error wtih `roslaunch morefusion_panda_ycb_video setup_dynamic.desk.launch`

[neubotech]

Hello,

Thank you for your work on morefusion. The package is quite comprehensive.

I have been trying to use it for ROS, and I encountered the following error while launching roslaunch morefusion_panda_ycb_video setup_dynamic.desk.launch:

Failed to get camera calibration parameters from the launch file. terminate called after throwing an instance of 'std::runtime_error' what(): No cam calibration

I could be wrong, but it seems like an issue with the orb_slam2_d435_rgbd.launch" file in themorefusion/ros/morefusion_panda_ycb_video/launch` folder. It should point to an .xml configuration file rs_rgbd.robot.814412071258.xml but it seems that it failed to load this calibration file calibration.

My question is:

1. does the *.xml file need to match the real-sense serial number?
2. is there a general procedure to follow or any particular "camera calibration" package you are using to generate this *.xml file? (I saw node in the .xml file, is that a hint?)

Attached is the screenshot of the error. Thank you very much for helping!

does the *.xml file need to match the real-sense serial number?

I don't think so. It should work even with imperfect camera calibration.

The camera calibration file is loaded from here: https://github.com/wkentaro/morefusion/blob/5c1036c19db0a55d24314336b09c01de11284a9f/ros/morefusion_panda_ycb_video/launch/orb_slam2_d435_rgbd.launch#L19

and the corresponding file is here. https://github.com/wkentaro/morefusion/blob/master/ros/morefusion_panda_ycb_video/config/RealSenseD435RGBD_814412071942.yaml

From the errors you show, it's probably worth trying to launch only orb_slam2_d435_rgbd.launch to see where the issue is coming from. Possibly it could be from new version of the orb_slam2_ros package: https://github.com/appliedAI-Initiative/orb_slam_2_ros
