The Camera display creates a new rendering window from the perspective of a camera, and overlays the image from the camera on top of it. For this display to work properly the sensor_msgs/Image topic subscribed to must be part of a camera, and must have a sensor_msgs/CameraInfo topic named camera_info alongside it. For example:
/wide_stereo/left/image_rect /wide_stereo/left/camera_info
The Camera display assumes a z-forward x-right frame, rather than the normal x-forward y-left robot frame.
