Abstract

ABSTRACT: This article reports a multi-camera system to determine the position of an object. By using novel copositioning and cameras in a wide range of orientations and viewing angles, the system solved the problem of dead zones and camera switching errors. When an object was close to a charge-coupled device camera, the system switched to that camera to become the focus by the algorithm. When an object left the optimum range of one camera, the system selected the next suitable camera to be the main detector. The position of the target and the grey level thresholds were continuously recorded and the changes were calculated. This interface system had the advantages of high positioning accuracy, fast response time, reduced noise in the light field, and no dead zones.
