Hi, Is it possible to use single CameraInfoManager object to get the calibration data for both left and right stereo camera? It looks from CameraInfoManager that we can get camera calibration parameter for only one camera and not both. Is there any other message for stereo camera which can get both left and right calibration parameters?

Warm Regards,

Even when using a stereo camera, there is no such thing as a "stereo camera info" message. Instead, the left and right cameras publish each publish their respective camera info. If you are writing a stereo camera driver node, then you should use a separate CameraInfoManager for each half. If you want to do your own stereo processing, then you should use the TimeSynchronizer class in the message_filters package to synchronize the cameras' image and camera_info topics.
