    We are running into issues when calibrating projector. When attempting, we get a yellow outlined box within the sandbox with the X and Y axis lines. Anything outside of the box is not recognized. When trying to use the disc to mark points, all the points are within the box. That tells me that we missed something or didnt calibrate something correctly. Im assuming the yellow box should be at the edges of our sandbox. We have a 30″x40″ sandbox with the lens height of 40″. Currently have about a few inches from edge of yellow box to edge of sandbox all the way around. We have gone through the first few steps many times and same outcome.

    Can you attach Kinect raw view? How you Kinect see the sandbox?

    I think I have the same problem, I can’t solve it use calibration, so I just move down Kinect and projector nearest to sandbox.

    The yellow box, and the image blobs inside the yellow box, are not meant to line up with your sandbox or calibration targets. They are just there to visually check for mismatches between your current sand surface and the captured background, and to check if your target disk gets recognized (yellow disk turns green).

    Align you camera and projector so that the camera sees the entire box, and so that the projector projects everywhere inside the box. Then calibrate, ignore the yellow rectangle, and run the main AR Sandbox application afterwards with -fpv. Everything should line up then.
