No display in stereo_view [closed]
Hi everyone !
I come to you again with a strange issue I'm getting with image_pipeline under kinetic.
I am using two uEye XS camera for a stereo setup (using tweaked aniqxu ueye_cam nodelet). Images are grabbed by two raspberry pi 2 under xenial. Although these camera can't be triggered and thus can't be synced, I successfully calibrate them. Afterwards, I got no error while running :
$ROS_NAMESPACE=/stereo/ rosrun stereo_image_proc with approximate_sync:=True _queue_size:=50
and disparity images are posted, as
$rostopic hz /stereo/disparity
shows a average rate of 2.1 fps.
However, when I try to display images using :
rosrun image_view stereo_view stereo:=/stereo/ image:=image_rect _approximate_sync:=True _queue_size:=100
I get only dark windows and no error or warning.
I got the same issue when I try to visualize only disparity using disparity_view
I was wondering if you people faced similar issues and eventually could give me a hand solving that strange issue.
You'll find a sample rosbag there, if that can be helpful !
I'm having the same issue with my setup. Everything looks right - even getting data pumped through the /stereo/disparity topic but stereo_view shows nothing but unresponsive windows.
Did you figure out an answer yet?
Unfortunately, no. I only needed rectify images in the end. I guess it could be due to approximate sync.
