星空运动背景中目标识别算法研究

针对微型航天探测器在星空运动背景下对目标识别的要求，提出一种基于图像配准与
边缘提取的差分算法。该算法将采集的连续两帧图像配准后差分，将差分图像二值化后与后一帧边缘提取后的图像进行逻辑乘，提取出目标物。计算机仿真结果表明该算法计算量小，识别效果好。

Abstract: In order to meet the needs of detecting the target under the moving space background by microspacecraft target detector .This paper proposed an algorithm-the image edge extract and deference base on image registration. The algorithm use image difference to the two collected and seriate image after image registration, then multiply the difference image after binarizing and the second image after edge extract by pixel, then detect the target. The result of simulation indicate that computational effort is low and detected result is good.
