visp_auto_tracker crashes on detection #55

Closed agjunyent closed 7 years ago

agjunyent commented 8 years ago

I'm trying to start using visp_auto_tracker to track a simple QR code (the one in the wiki). I can start it using roslaunch visp_auto_tracker tracklive_usb.launch, everything loads correct and I can see a window with the video of /image_raw.

The problem is that when I show the QR code to the webcam, all crashes with the following error:

[visp_auto_tracker-2] process has died [pid 12529, exit code -11, cmd /home/albert/catkin_ws/devel/lib/visp_auto_tracker/visp_auto_tracker /visp_auto_tracker/camera_info:=/usb_cam/camera_info /visp_auto_tracker/image_raw:=/usb_cam/image_raw __name:=visp_auto_tracker __log:=/home/albert/.ros/log/a987a6aa-4cee-11e6-87fa-b8ee651e75ac/visp_auto_tracker-2.log].
log file: /home/albert/.ros/log/a987a6aa-4cee-11e6-87fa-b8ee651e75ac/visp_auto_tracker-2*.log

Any help?

No idea. Are your camera_info parameters right. Check if the principal point is approximatly in the center of the image.

Sorry for the delay, been in holidays...

I'll try this week and say you something.

Thanks!!
