Abstract: A novel calibration and lens distortion correction of 3D reconstruction systems is introduced in this paper. Assuming zero distortion at the center of image, the parameter calibration and lens distortion correction of the CCD camera and the DLP projector is separated with the center points and all the rest points in the field. Furthermore, identification and correspondence of the interested points are automatically done because of the design target with standard circles and multicolor code of pseudo-random array during calibration. Experiments show that the proposed method is fast and convenient in the calibration of lens distortion.

Key words: 3D reconstruction, multicolor code of pseudo-random array, parameter calibration , distortion coefficient, error correction
