摘要
结合DM8168多核多通道的特点,设计了一个实时运动目标检测系统,能够实现视频数据的采集、实时运动检测、编解码以及传输等功能。采用Vi Be的目标检测算法,并利用中值滤波进行改进,解决了背景中容易出现Ghost区的问题,提高了运动目标识别能力。最后采用像素扫描标记法实现了目标跟踪。实验结果表明,所提出的方法能在达芬奇平台上实现实时鲁棒的运动目标检测和跟踪。
The design and implement of an intelligent surveillance system based on DM6446 is proposed. In this paper, firstly, we design and implement an motion detection system based on TI DM8168. By using median filter in initial phase of ViBe, the true real background would be obtained without ghost. In addition, objects can be tracked via pixel-labeled segmentation method. The experimental results show that the proposed method perform fast and robustly in the real-time motion detection system.
