视频运动矢量的获取FPGA实现

Video motion vectors acquisition by FPGA

提出一种视频运动检测的方法,通过融合帧间差法、色彩匹配法、区域特征匹配法、目标关键位置选取和光流场分析的视频运动检测方法,对视频数据流进行分析计算,获取运动目标的运动矢量。在Altera公司的FPGA试验平台DE1上,构建了视频运动检测矢量获取的验证系统。实践结果表明,该方法能够实时分析目标运动信息,快速准确获取视频流中目标的运动矢量。

A video motion detection method is put forward,which can analyze and calculate the video data flow to obtain motion vector of the goal.This method is the integration of frame difference,color matching,regional characteristic matching,choosing the key position of a goal and optical flow analysis.On FPGA DE1 test platform of Altera corporation,we verify the video game control system based on video motion detection.The practice shows that the method can analyze real-time motion information of targets,obtain the motion vector quickly and accurately.The control of the game achieves satisfactory effects.
