Hi I am still working on obtain my disparity image but still have problems, It seems that the problem is that the left/image_mono and the left/camera_info are not synchronized (the same for the right camera) I have increased the queue_size and set approximate_sync to true but i dont obtain better results. The command I use is rosrun image_view disparity_view image:=bumblebee2/disparity but I just obtain a gray window and this warning:

    Image messages received:      5
