System and method for optical flow calculation

The present invention discloses a system and method for optical flow calculation, the optical flow computing system comprising: a feature extraction module sequentially calculates feature values ​​of pixels corresponding to the input image; feature matching module sequentially calculates pixel corresponding to the input image an optical flow information; optical flow information and pixel values ​​of characteristic features of the monitoring module, the pixel corresponding to the point corresponding to the synchronization, and based on a feature value of the pixel corresponding to the point information to determine whether the output of the optical flow of pixels. Using hardware flow calculation is achieved in the present invention, the input pixel image feature matching and feature extraction, as the input image for each pixel, and the characteristic values ​​of the optical flow information corresponding to each pixel can be water is completed, it can provide a dense optical flow information. And since the value indicating the characteristic of only the pixels with good flow characteristics will be the light output, which can better reflect the actual movement of the objectives.
