Detailed Description

RGBD camera sensor class.

This class creates a few types of sensor data from an ignition rendering scene:

  • RGB image (same as CameraSensor)
  • Depth image (same as DepthCamera)
  • (future / todo) Color point cloud The scene must be created in advance and given to Manager::Init(). It offers both an ignition-transport interface and a direct C++ API to access the image data. The API works by setting a callback to be called with image data.
