Abstract： 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.
