摘要
基于达芬奇系列芯片TMS320DM8168,开发一个带智能目标跟踪功能的、视频监控与处理系统。系统含有基本的视频监控功能,并加入均值偏移算法和人机交互界面,使目标跟踪与用户操作有机结合在一起。该系统具有体积小,功能高度集成,算法实现高效,良好的用户体验和交互方式等特点。系统可以脱离计算机独立运行,从而能够大大降低设备成本。用户可以通过交互界面指定视频中的目标,启用智能分析算法对用户指定的目标进行跟踪,再由交互界面中绘出目标的运动轨迹,从而为用户提供快速、准确和智能的视频分析业务。本系统通过对均值偏移算法的实现并对其高度优化,解决了遮挡情况下目标的跟踪问题,提高了目标的跟踪能力和目标识别能力。
The design is based on TMS320DM8168, and it implements a video surveillance and processing system with the function of intelligent object tracking. This system has functions of basic video monitoring, tracking with the mean shift algorithm and human-computer interac- tion interface. Meanwhile it has several characteristics such as small in size, function highly in- tegrated, algorithm efficient, and good user experience interactive etc. This design can run in- dependently without computers, which can greatly reduce the costs. Users can point out the target in the video by the interaction interface, and then the system will use the intelligent analysis algorithm to track the specific target, and draw the motion path of the target. It offers quick, accurate and intelligent video analysis services. This system can finish the job of target tracking efficiently by using the modified mean shift algorithm which can track the target under occlusion successfully.
