扩展目标边缘数据空间排序算法

An Investigation on the Controllable Multi Frequency Readout Method of Area CCD in Dynamic Measurement

提出的边缘数据排序算法，用于扩展目标跟踪器设计之中；此算法采用链式数据结构，在寻找搜索起始点的基础之上，以距离最近为相邻象元之准则在链式数据结构中进行搜索，并重新链接成边缘数据的空间有序集合。节约存储器和排序速度快是本算法两大特点。因采用链式数据结构，原始数据与结果数据存贮器空间因共用而得到了节约；因可避免已搜索数据的重复操作，使搜索速度得以提高。文章的结尾给出了排序实例。

The frame frequency of photoelectric detection has a direct influence on the system performance in the imaging and tracking system.The principle and technical approach of the controllable multi frequency readout are proposed in the paper according to the electric properties of CCD output image signal.The related circuit design is finished.The experiments show that the controllable multi frequency readout is an effective approach for improving area CCD frame frequency.
