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.
