项目摘要

In this research, to realize an interactive broadcasting is aimed. Soccer video is concerned as example, and sequential images from optionally assigned view direction, are generated automatically. When object is sports which is played in large fields like soccer, it is very much difficult to capture by one camera for whole scene. However many cameras are used, only one selected camera is selected by expert and broadcasted. So automatic camera selection systems yield to viewers demand are desired. This is called an interactive video generation systems. The results are as follows,To construct an environments of image capture from multi-camera Many cameras are fixed around the soccer field and those images are analyzed. Camera for broadcasting will be controlled by the results of analysis.Detection and tracking of players and ball using image sequence from multi-camera To detect a ball in one frame, template matching technique are applied, and to detect players, background difference images are used. After that, inter frame tracking algorithms are proposed and applied. The algorithms are well worked and useful to make loci of players.To develop an algorithm for error correction caused by occluded player When a player is occluded by other player in image from one camera. An occlusion should not exist in images from the other camera, or be estimated players and ball position.To decide the best view direction Information from tracking of ball and player are concerned to feature value. The analysis of those feature value vector, gives the best view directionTo recognize play type Players around the ball are detected, position and velocity information are used for distinguish soccer play such as pass, shot tackle and so on

本研究以实现互动式广播为目的。以足球视频为例，从任意指定的视角自动生成序列图像。当目标是在大场地上进行的体育运动时，如足球，很难通过一个摄像机捕获整个场景。无论使用多少台摄像机，专家只会选择一台摄像机并进行广播。因此，自动相机选择系统屈服于观众的需求是期望的。这被称为交互式视频生成系统。研究结果如下：为了构建一个多摄像机的图像采集环境，在足球场周围安装了多个摄像机，并对这些图像进行了分析。利用多摄像机图像序列对运动员和球进行检测和跟踪为了在一帧图像中检测到球，采用模板匹配技术，为了检测运动员，采用背景差分图像。在此基础上，提出并实现了帧间跟踪算法。提出了一种运动员被遮挡时的误差修正算法。该算法将球和运动员的运动轨迹信息作为特征值，通过对运动员和运动员的运动轨迹进行分析，确定最佳视角方向。通过对这些特征值向量的分析，给出了最佳的视角方向。在比赛类型识别方面，检测出了足球周围的球员，利用位置和速度信息来区分足球比赛中的传球、铲球等
