一种结合地理信息的视频追踪分析方法及系统

Video tracking analysis method and system combined with geographic information

Abstract

The invention provides a video tracking analysis method and a system combined with geographic information. According to the invention, an object is confirmed and the characteristic information thereof is extracted through initialization, so the information of the object, such as, initial position, starting time, the next position and the required time spent in reaching the next position, is obtained; the video in the specific time section of the next position is subjected to matching; the position information is subjected to processing according to the matching result; and the path information of the object is stored and output. According to the invention, the camera relevance of a monitoring system is effectively utilized, the network space of the cameras and the time relevance is combined, and the object driving path can be automatically analyzed based on the geographic information obtained through the cameras.
本发明提供了一种结合地理信息的视频追踪分析方法及系统,通过初始化,确定目标物体并提取其特征信息,并获取目标物体的初始位置及时间起点信息还有目标物体的下一位置及所需时间信息,然后对下一位置规定时间段内的视频进行匹配,接着依据匹配结果对位置信息进行处理,最后存储并输出目标物体的路径信息,有效利用了监控系统中各个摄像头之间的关联性,将摄像头网络空间与时间相关性融合,结合摄像头地理位置信息,自动分析出目标行驶路径。
