2016-08-01 23:11:50 -0500	commented question	No display in stereo_view Unfortunately, no. I only needed rectify images in the end. I guess it could be due to approximate sync.
2016-07-26 15:08:26 -0500	commented answer	No display in stereo_view Thank you for the answer. Actually I already came across that tutorial. DIdn't help. The think is that I do not even get close to display images at all. I only get 3 windows (left/right/disparity) but nothing is ever shown in them, they are not even rescale to fit the size of the images

2016-06-22 08:19:09 -0500	asked a question	No display in stereo_view 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.

2016-05-31 09:24:58 -0500	asked a question	Can ueye_cam send jpeg image from XS camera Hi, I am starting to use ueye_cam on a rpi 3 under Xenial and Kinetic and it's working very smoothly. So for I realised that there was a special launch file for bggr xs camera. Same launch file also works with bgr8 encoding. However, I was wondering if ueye_cam could directly post image encoded in jpeg from the the uEye XS since the HW naturally support jpeg encoding. Thank you for your answers !
