Visual analysis of human motion has been receiving increasing attention from researchers in the fields of image processing and computer vision during the past few years . it has a lot of applications in virtual reality , smart surveillance system , advanced user interface , motion analysis and video compressing , etc . this paper focuses on the technology of human motion tracking based on video , first , we make a summarization of the domestic and overseas status of the research in this field . on the basis of this , we analyse the technical difficulties of human motion tracking . as most of the existing model - based methods of human motion tracking perform not so good in some situation as they need mannual intervention , and also the precision of tracking is not so satisfying during the research of tracking of walking people because of the self - occlusion of legs , this paper proposes an algorithm of automatic detection and tracking of legs of the walking people based on monocular image sequences , in which we analyse the features of walking people , track the five joints of lower limbs , get various parameters , and then re - construct the walking process . the main research achievement is as follows : 1 ) we propose an algorithm of markerless automatic extraction of leg skeleton . first we divide the video into continuous image sequences , after background subtraction , the satisfying human region could be extracted , then we get a single - connected region by converting the rgb image to binary image and median filtering . afterwards , the contour of lower limbs in the frame with a widest boundingbox is detected , using sobel operator , to find the ankle joint of leg behind according to the features and rules of walking , then , the joint of knee of leg behind , hip , ankle of leg in front , knee of leg in front could be got in turn . so , model of leg skeleton is constructed 首先將視頻分解成許多連續的靜態圖像幀,經過背景去除,把感興趣的人體區域提取出來,通過二值化,中值濾波等預處理方法得到只有人體的一個單連通區域,然后用sobel算子檢測出boundingbox最寬幀中人體下半身的輪廓,根據運動規律及特征找到后腿踝關節點,結合從boundingbox最窄幀中所獲取的腿長依次得到后腿膝關節,跨部關節,前腿踝關節,前腿膝關節四點,從而構建出腿部骨架模型。 2 )實現了人體步行腿部骨架的跟蹤算法。在完成對腿部骨架模型的自動初始化之后,本文對跨關節、膝關節及踝關節分別采用運動建模、圓周相交定點算法、運動預測及預測點周圍搜索rgb相似矩形塊三種方法確定每一幀中其實際坐標,從而重構出腿部骨架的運動過程。
