Camera Calibration and Selective Tracking of a Moving Object by the Collaboration of Multiple Cameras

摘要

We discuss a system which utilizes the collaboration of multiple cameras and traces moving objects specified by a user. Three-dimensional shape reconstruction and collaborative tracking of objects require a camera calibration to evaluate the position and orientation of each camera. We introduce a dynamic camera calibration method which lets more than one camera to track a moving object simultaneously and evaluates calibration data. The method is incorporated with our object-tracking system using multiple cameras, and its validity is confirmed.
