摘　　要：物体在不同介质中的运动轨迹受到介质的粘度、比重的影响,将物体的运行轨迹从图片中提取出来,有助于分析物体在不同介质中的运动规律。本文中动态视频转换成静态bmp图片序列,采用差影法针对bmp图片进行处理,再将处理后的系列bmp图片进行整合,得到物体的运行轨迹,呈现出物体运行轨迹曲线。结果表明差影法对物体运动轨迹的模拟可靠有效。The movement track of the objects in different medium will be influenced by the medium viscosity, specific gravity. To extract the trajectory of the object from image is conducive to analysising the motion law of objects in different medium. In this paper, the dynamic video is transformed into static BMP image sequence,and then using subtraction method to processing the images,at last, integrating the series of BMP images to get the object＇s trajectory.The results show that using subtraction method to get the trajectory is reliable and effective.
