Have you subscribed to any of stereo_image_proc's advertised topics (e.g. stereo_test/disparity
)? To avoid unnecessary computation (both in stereo_image_proc and the source camera driver nodes) it only subscribes on demand. From the wiki docs:
All processing is on demand. Color processing is performed only if there is a subscriber to a color topic. Rectification is performed only if there is a subscriber to a rectified topic. Disparities and point clouds are generated only if there is a subscriber to a relevant topic. While there are no subscribers to output topics, stereo_image_proc unsubscribes from the image_raw and camera_info topics.
