摘要
人体运动部位跟踪识别是一个动态过程,传统的视频定位方法不能有效分辨动态的运动部位特征点,跟踪定位的准确性不好,为了提高运动部位定位的动态性和准确性,提出一种基于激光跟踪技术的运动部位定位方法,采用激光跟踪扫描技术进行人体运动的视频帧图像采集,对采集视频帧图像进行模板特征匹配,建立运动部位跟踪的目标跟踪模板区域,采用粗略搜索和精细搜索相结合方法进行运动特征点提取,根据图像的空间边缘分布特性判断是否存在运动部位,采用区域块分割方法实现运动部位的准确定位。仿真结果表明,采用该方法进行运动部位定位的准确度较高,运动图像输出的质量较好,提高了运动部位特征点的匹配和动态跟踪能力。
Human motion tracking and recognition site is a dynamic process. Traditional video positioning method can not effectively distinguish the feature point of dynamic motion parts,and has poor accuracy. In order to improve the dynamics and accuracy of motion parts location,proposed a motion parts location method based on laser tracking technology. Using laser tracking scanning technology to capture video frame image of human motion. Matching the template features of obtained video frame image. Constructing target tracking template zone of the motion parts. Extracting motion features through the coarse search and fine search method. Judge the existence of moving parts according to spatial edge distribution characteristics. Realize accurate positioning by regional block segmentation method. Simulation results show that this method has high positioning accuracy,output quality,and improves matching and dynamic tracking abilities of moving parts feature point.
