线阵CCD图像不失真采集算法及实现

Algorithm and Usage for no distortion image Acquisition process from liner CCD

综合分析线阵CCD摄像系统在正常视距范围内,以相对速度扫描目标物体,得到完整图像信息及相类似过程中,其中光学系统设计、线阵CCD器件性能要求、获取图像需求分辨率、以及采集对象匀速相对移动速度、放置条件等各方面重要因素,在获取不失真图像工程条件下的要求及影响,推导并提出,在不同应用条件下的可调整线阵CCD采集不失真图像的算法、公式。并举例介绍在实际工程中实现具体应用的方法。

Take comprehensive analyze on the process of photoelectric image signal full collected in no distortion by linearray CCD organ image collect system, focus on the parameter of camera lens, the display resolution timing information, horizontal and vertical video signal memory demand to load, and the target object conditions like velocity compare to system, distance to lens and so on problems as the several important points. Find the relationship in logic and in formula between them. Then bring the conclusion of no distortion arithmetic for collecting whole image by line-array CCD out. For next, introduce and explain how to use the expressions under restrained conditions in actual program, at last, give the example to show how it work.
