A method of 3D reconstruction based on single camera

The method of 3D reconstruction from multi-view of the object with single camera is proposed in this paper. The images of the planar pattern from different views are captured by the single camera. The internal and external parameters of the camera are calculated precisely with Two-stage camera calibration method. On this basis, the image points of calibration pattern can be matched and reconstructed. Experimental results show that: the flatness of reconstructed planar pattern is about 0.006mm; the position error of sign is about 0.012mm. The proposed method is high-accuracy, simple, flexible and effective.
