PointCloud visualization This example demonstrates how to start the camera node and make it publish point cloud using the pointcloud option. If you're using a LaserScan display, the only available channel will be the "Intensity" channel. An option to do for now until the PointCloud class is wrapped up for C# is to obtain the camera intrinsics (for the depth camera if using the raw depth, or color camera if using depth aligned to color) and implement the Pinhole Camera Model (which is what the PointCloud class does internally). This section explains how the color/position of a point is computed for each channel type. Support for Kinect for Windows v2 and Kinect for XBox One sensors Support for Orbbec Astra and Astra Pro sensors I remember reading that PointCloud is going to be retired in future a versions in favor of PointCloud2. There is a function to convert from one to another, but the documentation is very poor.
