Hello,
I have a stereo vision system. Therefore, I'm using stereo_image_proc to get the rectified images as well as the pointcloud. As far as the rectified images, I get them at the same frequency as I get the raw images from the cameras (30 Hz), but the pointcloud is only 2 Hz, which makes it hard to do something with that. I only have the node to obtain the images from the cameras and stereo_image_proc. Is there anything else that I should be doing? Could stereo_Image_proc take *that long* to process the point cloud?
