Design And Implementation Of Target Tracking Algorithm Based On Real-time Monitoring Video Of Mall PTZ Camera

At present, the monitoring system of the shopping center is usually monitored by the monitor, and the tracking of the target is achieved by the operation of the keyboard joystick. Mall PTZ camera control system in this article is selected for moving target tracking, the video monitoring system can automatically track the selected target, and can zoom in and out scene area, convenient movement observation of the moving target,so as to improve the efficiency of video surveillance. The main research contents of this paper:Firstly, this paper introduces the classification of video surveillance system, and builds the platform of variable monitor and control system.Then, we introduce the Camshift algorithm and simulate the traditional Camshift tracking algorithm. Then we improve the Camshift tracking algorithm by using the adaptive feature of color feature, HOG feature and LBP texture feature. Therefore, we propose a multi-feature Adaptive fusion Camshift tracking algorithm. In each frame of video sequence images, we lock the monitoring target, record the target location. The algorithm reduced the impact of lighting, occlusion and other factors of interference, so can improve the tracking algorithm stability.Finally, we build the automatic tracking model of the PTZ lens and the lens auto zoom model. According to the video screen to monitor the target movement speed and size, using these two models automatically match the speed and the lens multiples of the PTZ, real-time tracking of the monitoring target and screen zoom, and ultimately the monitoring target is always the appropriate size display in the video center area. And through the program to achieve the mantra PTZ lens target automatic tracking algorithm and zoom control.In order to verify the effectiveness of the tracking algorithm, we use HikVision camera for experimental simulation. We recorded through the HikVision camera video, the target can be tracked. The results show that the design of the shopping malls PTZ lens tracking system, the system has a good real-time, a stable tracking effect.
