摘　　要：针对交通路口的视频监控,传统多路视频组成电视墙的监控方式,存在视频利用率低、单个摄像头视野局限性、信息缺失以及多视角显示凌乱等问题。全景视频是将多个视频流的重叠区域逐帧进行拼接,能在不降低分辨率的同时有效扩大监控人员的视野,已成为交通监控领域的研究热点。本文在分析交通视频监控需求的基础上,研究了视频拼接的相关技术,通过在配准和融合两方面优化拼接算法,在确保输出质量的同时实现快速视频拼接。With the rapid development of urban traffic,traffic video monitoring has become an essential technical means to achieve intuitive and efficient management of traffic conditions.In view of the video monitoring at traffic intersections,the traditional multi-channel video composed of TV wall has some problems,such as low utilization rate of video,limited field of view of single cam⁃era,lack of information and messy multi view display.Panoramic video stitches the overlapping areas of multiple video streams frame by frame,which can effectively expand the vision of the monitoring personnel without reducing the resolution.It has become a research hotspot in the field of traffic monitoring.Based on the analysis of the demand of traffic video monitoring,this paper studies the related technologies of panoramic video mosaic algorithm.By optimizing the mosaic algorithm in the aspects of registration and fusion,the fast video mosaic is realized while ensuring the output quality.
