基于异步时序的高帧频相机垂直拖尾处理

介绍一种高帧频相机垂直拖尾影响的解决方法，该方法同时考虑连续采集模式下帧间图像和像元合并（binning）技术的影响。与常用的静态图像拖尾处理的算法如逆向逐行修正算法相比，该算法非常适用于连续图像拖尾处理，特别是经过Binning后获取的图像。在某自主研制的基于异步时序的40 000 帧/秒高速相机中应用该方法，有效去除了拖尾影响。最后，运用该方法处理的图像验证了算法的有效性。

Smear correction of high frame rate camera based on asynchronous CCD drive

The vertical smear correction of a high frame rate camera has been carried out, which takes a series of images and CCD vertical binning into consideration. Compared with the traditional arithmetic for static images, such as reversely stepwise correcting method, the arithmetic presented in this paper is fit for continuous images, particularly for the images acquired with binning. The method has been applied to a newly developed high frame rate camera based on asynchronous CCD drive which is capable of operating up to 40 000 frames per second, and the processed images proved the effectivity of this method.
