基于光流的物体移动速度检测技术

通过采集目标物体的运动图像,根据移动物体运动场和光流场的关系,由运动主方向的原理,确定出物体移动的方向;采用一种基于金字塔式的L-K算法对移动物体的光流速度进行计算;把图像中的光流速度转化为物体的实际移动速度。实验结果表明,该算法能有效地检测出物体的实际移动速度。

The Speed Detection Method of the Moving Object Based on Optical Flow

By collecting the images of the moving object , the relationship between the motion field and the optical flow of the moving object is used to determine the object movement direction based on the theory of main movement direction. The optical now speed of the moving object is calculated by the pyramid L-K algorithm. The optical flow speed of the image is translated into actual speed of the moving object. The experimental results show that this algorithm can detect the actual speed of the moving object.
