摘　　要：微型航天探测器主要是对空间目标探测捕获,然而微型航天探测器在空间对目标物成像时,目标物、背景和探测器之间存在相对运动,目前还没有好的运动背景中运动目标捕获的算法。为了避免这种相对运动带来的影响,文中提出了一种改进连通域目标捕获的算法,并在DSP TMS320C6416图像处理系统上实现了改进的连通域捕获算法,结果表明算法能满足微型航天探测器捕获效果和实时性的要求。The mainly task of microspacecraft detector is to identify target in the space, but there isrelative movememt among targets, background and detector,and there is not a good algorithm to identify target under moving background. In order to avoid the influence of their relative movememt, an improved connected algorithm of target detection was proposed in this paper, This algorithm can commendably detect the moving target under moving space background, and the algorithm was simulated in the DSP TMS320C6416 system. The results indicate that the improved connected algorithm meet needs of identifying target and real time of microspacecraft detector.
