摘要
针对海防视频监控系统中运动目标跟踪的问题,本文提出了利用上位机软件进行目标跟踪的设计与实现方案。文章首先介绍了海防视频监控系统的总体组成及工作流程;然后阐述了相关跟踪算法与金字塔分层搜索算法的实现,以及利用序贯相似检测算法与金字塔算法相结合的目标检测方法;最后描述了用目标偏移量对云台进行控制实现自动跟踪的过程。通过在实际海防视频监控系统中的应用,对运动目标跟踪实现方案的有效性、实时性等特性进行了验证。
According to the problem of moving object tracking in the coastal defense video surveillance system, the scheme of using software to track objects is proposed in this paper. Firstly, the hardware and software structures of the system and the flow of work are introduced briefly. Secondly, this paper describes the implementation of the correlative matching algorithm and the pyramid-layered searching algorithm. The sequential similarity detection algorithm combined with the pyramid-layered matching algorithm is used to detect moving objects. In the end, this paper describes the process of moving object auto-tracking using the offsets of the moving object to control the servo. It is proved that the scheme satisfies the demands of the coastal defense video surveillance system in accuracy, real-timeness, and so on.
