Abstract
A method and system are provided to calibrate multiple camera devices to perform multi-camera tracking of one or more objects. The method and system identifies one or more common (or matching) calibration points on both of a first image or video stream captured by a first camera device and a second image or video stream captured by a second camera. Each of the one or more common calibration points are in a field of view of the first and second camera devices. The method and system further determines coordinate information for the first and second camera devices from the one or more common calibration points, and evaluates the coordinate information to determine alignment parameters, which reflect a location and orientation of the second camera device relative to the first camera device.
