The Application Of Video Tracking And Identification Technology In Sea Route Video Surveillance

Xiamen port authority has established sea route surveillance system since 2005, and has completed the first stage. This paper introduces video tracking and identify technology into the surveillance system to achieve computer assisted management; and extract vessel movement data from video signals which will then be input to the integrated information bus, to stop the surveillance system being an isolated information islands.The goal of this paper is how to extract vessel movement data from video signals. Through the study of goal identify methods and the characteristic of video signals above sea areas, based on edge detection Sobel algorithm, we design the software which is able to analyze two routes of video signals and meanwhile record the time and spot of vessels in the database of the system. The record can also be used by other information system.The result of this research provide Xiamen Port Authority a different mode of the harbor and waterway's supervision. It merged more Information Technology into the Administrative Supervision. Through the monitoring video signal by the computer, it can effectively change the video surveillance system an evidence provider to an early-warning system. There is a realistic meaning to the Security Monitoring System. In the meantime it is also a great try to the development of the existing video supervision system to integrate the video supervision system into the general information system through extracting the data and sharing them, which will greatly improve the effectiveness of the comprehensive supervision system by comparing the true data from the video signals with the data from other system. The technology also keeps pace with the trend to integrate the distribution system and decrease the isolated information islands.
