This paper studies to get the image of thenar by using a video camera, and carries on the necessary image processing by software with the information captured, and gets the ideal image to provide the image data basis for follow - up cad after the processing such as median filtering, sobel or kirsch ' s operator edge detection, image reversal and image enhancement etc. in this paper, the pressed image information of thenar captured by camera have been carried on processing and analyzing, and the result has been compared with that of image acquired by the scanner
本文研究了利用攝像頭獲取腳底圖像，再通過軟體將所獲信息進行必要的圖像處理，經中值濾波、 sobel或kirsch運算元邊緣檢測、亮度調整及反置、圖像增強等處理后，得到滿意的圖像為后續的cad提供圖像數據依據。本文對攝像頭採集的足底受壓圖像信息進行了處理和分析並與掃描儀的圖像處理結果進行了比較，由結果得知攝像頭輸入方法是一種簡單實用的輸入方法，且能很好的滿足設計要求。 -

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，然後用sobel運算元檢測出boundingbox最寬幀中人體下半身的輪廓，根據運動規律及特徵找到後腿踝關節點，結合從boundingbox最窄幀中所獲取的腿長依次得到後腿膝關節，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演算法。在完成對腿部骨架模型的自動初始化之後，本文對跨關節、膝關節及踝關節分別採用運動建模、圓周相交定點演算法、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。 -
In the telerobot, there are video system and sensors used to measure the hardness of the grabbed object and the resistance. moreover, the image of on spot is transmitted to the screen in front of the operator by wireless communication system. in the meantime, the hardness of the grabbed object and the resistance in working can be judged by the feedback force of the master manipulator
為提高遙操作的視覺臨場感，提出虛擬現實輔助遙操作的控制策略，不僅為操作者提供友好的人機交互界面，彌補單一視頻反饋無線通訊伴隨的圖像抖動及模糊不清，而且在一定程度上緩和了遙操作系統中普遍存在的大時延問題所帶來的不利影響。 -
