Claim One:
1. A kit of parts for generating calibration information for a media projector, comprising: a media projector that shines at least one test spot on a surface, the test spot corresponding to a known pixel coordinate of the media projector; a tracking apparatus able to be positioned on the surface at the test spot, the tracking apparatus comprising: one or more light sources that strobe according to a strobe pattern associated with an object ID; and a wireless radio for communicating with a computing device; at least two cameras, each of the cameras able to capture images of the one or more light sources; and a computing device able to obtain at least the images from the at least two cameras, the computing device configured to at least: analyze the images to determine the strobe pattern of the one or more light sources; identify the object ID based on the strobe pattern; determine a real-world X,Y,Z-coordinate position of the one or more light sources by at least determining a pixel location of the one or more light sources in the images; generate a mapping between the known pixel coordinate of the test spot and the real-world position of the one or more light sources; and output the mapping as calibration information for the media projector.
