Using a webcam with Point Cloud Library (PCL)

Is it possible to use a webcam with Point Cloud Library (PCL) or do I need to use a depth-sensor camera?

It all depends on what you want to do. There is some functionality in PCL for processing 2D images (point clouds with only x and y coordinates basically) - e.g. edge detection but I guess PCL is not the place you would first go for that functionality (see OpenCV).

If you want to make best use of PCL you need a 3D point cloud. To get there from webcams you need to use one of, in order of increasing difficulty:

  • A multiple camera setup.
  • Structure from motion.
  • Depth from single images.
