In this paper, through analyzing and studying the physical structure and working principle of Charge-coupled Device image sensor ( CCD), we propose a speed measurement using single-frame fuzzy image of moving object based on the dynamic response of CCD. 本课题通过对CCD图像传感器物理结构、工作原理的分析和研究,提出了基于CCD图像传感器动态响应特性的单帧模糊图像速度测量方法。
