The camera calibration method is based on the 2D plane target\'s camera calibration method that is proposed by Zhang Zheng-you et al. Intrinsic and extrinsic parameters of fixed-focus camera are obtained and the precision and the error analysis of Camera calibration are done. The multi-sensor vision system errors are obtained. The error average value is 3.39 mm in X lateral, 0.43 mm in Y lateral, and 1.52 mm in Z laterals. The precision might satisfy the multi-sensor vision system\'s localization request.(3) The goal position and intensity have difference between the visible light image and the near-infrared image because of their image formation mechanism, resolution and field of view differences.
