Abstract
This paper presents a calibration method to align the coordinate system of each camera together in a multi-camera-projector system using a flat surface object. The method identifies the geometric relationship between each camera’s coordinate system with the physical feature points from the 3D model of the calibration target sharing the minimum absolute bi-directional phase difference. Experimental results shows that pixel-level accuracy of 3D model alignment can be achieved.
