| 摘 要： | 利用CCD图像采集设备，结合计算机图形编程，实现了对动态图像的扫描处理，从而获得跟踪点的运动轨迹图像．通过对CCD成像机理分析，实现了不同布置条件下由图像坐标到实际坐标的转换，并可直接获得跟踪物体的运动速度、加速度及倾斜角度等基本数据结果．该方法大大减轻了试验图像分析的工作难度及工作量。为深水网箱等动态物体的运动分析提供了高效手段．

| Abstract: | Based on the image technology, the motion trajectory of tracing points can be acquired automatically by scanning the pictures captured via a CCD camera. Coordinate transformation from pixel coordinate to geometrical coordinate under different setting conditions is given according to the CCD image formation theory. The motion velocities, accelerations and inclination angles of the tracing object can be acquired directly by analyzing the motion trajectory under geometrical coordinate. This method introduced can be used as a reliable and effective approach to studies of motion responses in moving objects, such as ships, sea cages, etc.. |
