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.

2建立了基于2D圆控制点的摄像机标定试验系统，对多源传感器视觉系统的摄像机，采用张正友等人提出的基于2D平面靶标摄像机标定方法进行了标定试验，得到了多源传感器视觉系统的摄像机内外参数，并对标定结果进行了精度和误差分析，得出视觉系统在X方向误差均值为3.39 mm，Y方向误差均值为0.43 mm，Z方向误差均值为1.52 mm，可以满足多源传感器视觉系统的定位要求。
