摘要
图像拼接技术应用范围十分广泛,如全景图片、城市建模以及视频监控等工程应用领域。针对机场中多台超高清摄像机监控的场景,设计了一种全景多路超高清监控视频拼接系统。该系统利用具有重叠区域的多路视频进行实时拼接,从而形成具有更大视角的全景视频,给决策人员提供全面而有效的支持。系统将传统的图像拼接技术运用在视频拼接上,采用分布式的系统架构并设计了一种视频文件传输算法,保证了系统流畅、稳定地运行。首先介绍了该系统软硬件环境,给出了系统的总体设计;其次介绍了系统的关键功能设计以及主要界面实现;最后进行了实验测试,得出相关实验数据。经过测试,该系统实现了8路4K视频的拼接,显示流畅,无明显拼接痕迹,且对一帧的处理时间小于40 ms。
Image stitching technology is widely used in engineering fields,including panoramic pictures,city modeling and video surveillance.A panoramic multi-channel UHD(Ultra High Definition)surveillance video stitching system was designed for scenes monitored by multiple UHD cameras in the airport.Through real-time stitching multi-channel videos with overlapping areas,the system forms a panoramic video with a larger angle of view and provides comprehensive and effective support for decision makers.In addition,the system applies the traditional image stitching technology to video stitching,adopts a distributed system architecture and designs a transmission algorithm of video files,which ensures the smooth and stable operation of the stitching system.This paper firstly introduces the software and hardware environment of the system,and presents the overall design of the system;secondly,it introduces the design of key function of the system and the interface implementation of the main system;finally,it presents relevant experimental data obtained from an experimental test.After testing,this system has realized the stitching of 8-channel 4K video,with its features of smooth display,no-obvious-stitching traces and less than 40 ms of processing time per frame.
