摘要： 在将ＣＣＤ安置于ＣＣＤ相机焦面的过程中，需要确定相机光学系统的焦面位置（简称定焦）；由于定焦过程中采用了计算机技术，将人为因素的影响降至最低，而测试设备、测量环境等因素成为影响测量精度的主要误差来源。对此，应用误差理论，按误差的作用类型分别进行了分析

Abstract: Computer is used to measure the focal plane of CCD camera in order to fix the CCD in it.It's called Computer Focus.The artificial error is minimized by this method.Therefore,both environment and devices are the main sources of measurement error,which can effect the accuracy of measurement.In this paper,We discuss and analyse the error of Computer Focus according to the error theory.
