I have a bag publishing left and right camera_info and image_rect_color topics.
How can I use stereo_image_proc to get the point cloud?
stereo_image_proc/disparity nodelet subscribes to image_rect and gives out disparity, which can be used by the stereo_image_proc/point_cloud2 nodelet.
Do I need to modify the source code, make a custom launch file or this can be done via an easier way that I am unable to see immediately?
Afai understand, I have to convert to mono image and then maybe remap or publish to the relevant topic.
ROS_NAMESPACE=stereo rosrun stereo_image_proc stereo_image_proc -> here the whole node subscribes to raw images which I don't have as a topic.
