摘要
对CCD器件的非均匀性校正的理论方法进行了讨论、分析和比较,并对32×64元硅化铂肖特基势垒红外焦平面器件进行了响应率非均匀性的校正,针对该器件响应率非线性度大、传输率低、疵点数目多和噪声大等问题,选取先进的多点定标分段校正算法,实现了实时校正及显示。校正后,不均匀度为2%,图像质量明显得到改善。
The paper describes systematically several methods of nonuniformity correction for 32×64 pixels PtSi FPA IRCCD designed by the Shanghai Institute of Technical Physics, Chinese Academy of Sciences, and makes a comparison and analysis between them. An advanced method of multi-point correction was developed in software and hardware. The results show that the method reduces the influences of the bad pixels and low transfer efficiency, and the image can be corrected and displayed in real-time, and the degree of nonuniformity drops to below 2%. It is quite obvious that the quality of the image is improved, and the desired results are achieved.
