CCD摄像机的误差及其检校

Inherent Erors of the CCD Camera and Their Testing Methods

在利用面阵CCD摄像机进行摄影测量和检测的系统中,CCD摄像机所产生的误差是系统的主要误差,这种误差是在图像输入的过程中产生的。CCD摄像机的误差一般分光学误差、机械误差和电学误差。在摄像机光学镜头与CCD器件质量比较好的情况下,其主要表现是电学误差,重点讨论电学误差及其检测。

Inherent errors from CCD camera are the main errors in the CCD photographic measurement and detection systems. The errors are resulted from the input procession of images. They affect the accuracy of the systems examination, so they cant be ignored. The errors usually include optical errors, mechanical errors and electric errors. The paper mainly discusses the sources of these errors, and the methods to correctly check these errors, in order to improve the accuracy of the system.
