通过对像增强器信噪比常用测试方法的研究与分析,提出了一种对CCD摄像机采集的图像进行处理的新的信噪比测试方法,解决了在常用信噪比测试方法中待测参数多、采用测试仪器多的问题。利用新的测试方法和搭建的实验系统不仅实现了数据的统一处理,而且还可以分析照度与信噪比的关系。
Through the research and analysis of commonly used test methods of image intensifier signal to noise ratio, a new signal to noise ratio test method is proposed to deal with the image collected by CCD camera, which solves the problem that the parameters to be measured More, using more test equipment problems. The use of new testing methods and experimental system set up not only to achieve a unified data processing, but also can analyze the relationship between illumination and signal to noise ratio.
