Abstract
This paper introduces a calibration framework designed for dual-resolution dual-camera structured light systems. The calibration process for each camera-projector pair adheres to a conventional pixel-wise calibration method for structured light systems. To align the two cameras' coordinate system, the method employs a white planar object and virtual feature points. These points are generated based on the dual-directional absolute phase maps obtained from each camera. By leveraging the pixel-wise calibration results from both single camera-projector pairs, this approach determines the geometric relationship between the camera coordinates via rigid transformation. Experimental results demonstrate the proposed method's high calibration precision for each camera-projector pair and the accurate alignment of coordinates between these two cameras.
