项目摘要

The purpose of this research is to establish a paraliel tracking vision technique which can continue carrying out tracking in detail and in high resolution simultaneously. By using two or more television cameras with high resolution but narrow view, two or more independently moving targets can be tracked simultaneously. For this purpose, the author have investigated the following topics as concrete research items and obtained several results described below1. Simultaneous detection and tracking of two or more moving targetsFirst, the author have tackled development of a techique to detect and track two or more moving targets. Specifically, difference between frames, masking processing, optical flow extraction, and statistical classification of the extracted flow are used to extract and classify motional elements in a view field. As a result of the extraction and classification, detection and tracking of moving targets have been succeeded2. Realizing robustness of optical flow extractio … More n by incorrect correspondence controlThe optical flow extraction mentioned above uses correlation based template matching. In order to realize robustness of the optical flow extraction, the author have tackled control of incorrect correspondence in the matching process. Concretely, success-or failure check of the matching is introduced. It considers situation of correlation value distribution in partial area, especially, existence of a peak, sharpness of the peak, and so forth. As a result, matching error and fake flow extraction can be controlled and avoided. Moreover, by matching both direction of time-axis order mutually, it succeeds in controlling extraction of fake flow except for fake correspondence of the object boundary. Its matching is impossible in essence3. Wide range tracking by cooperation of two or more camerasThe developed technique to extract and classify motional elements in the single camera view is applied to two or more cameras to realize wide range tracking. This is realized by giving template matching both temporally and spatially. Vision processing with each camera is so independent. And high parallelism for every camera can be expected. Thus parallelizing of the technique improve its performance Less

本研究的目的是建立一种并行跟踪视觉技术，可以同时进行细节和高分辨率的跟踪。通过使用两个或多个具有高分辨率但窄视野的电视摄像机，可以同时跟踪两个或多个独立运动的目标。为此目的，作者对以下主题作为具体研究项目进行了调查，并获得了以下几个结果1。同时检测和跟踪两个或多个运动目标首先，作者研究了一种检测和跟踪两个或多个运动目标的技术。具体地，使用帧之间的差异、掩蔽处理、光流提取和所提取的流的统计分类来提取和分类视场中的运动元素。作为提取和分类的结果，运动目标的检测和跟踪已经成功2。光流提取鲁棒性的实现 ...更多信息上述光流提取使用基于相关的模板匹配。为了实现光流场提取的鲁棒性，作者解决了匹配过程中不正确对应的控制问题。具体地说，介绍了匹配的成败检验。它考虑部分区域中的相关值分布的情况，特别是峰的存在、峰的尖锐度等。因此，可以控制和避免匹配误差和假流提取。此外，通过相互匹配的时间轴顺序的两个方向，它成功地控制提取的假流除了假的对应关系的对象的边界。它的匹配在本质上是不可能的。两台或多台摄像机协同大范围跟踪将所发展的单台摄像机运动元素提取和分类技术应用于两台或多台摄像机，实现大范围跟踪。这是通过在时间和空间上进行模板匹配来实现的。每个摄像头的视觉处理都是独立的。并且可以预期每个相机的高并行性。因此，该技术的并行化提高了其性能
