Abstract

3D surface reconstruction plays an important role in reverse engineering, which can be implemented by machine vision techniques. In the techniques, the calibration of the intrinsic and extrinsic parameters of a camera is very crucial to ensure the 3D reconstruction accuracy. This paper will present a neural network method for the calibration. This method uses weight matrixes to calculate the transformation matrix of the 3D points in a world frame against their corresponding 2D image pixels, and then the intrinsic and extrinsic parameters can be readily extracted from the matrix. The experimental results have shown that the method can obtain a precise calibration result.
