【摘要】 随着社会的快速发展,目标跟踪系统的发展已经越来越成熟,它被广泛应用于军事、工业和商业等领域中,已经成为了现实生活中不可缺少的一部分。智能化的提出,更促进了目标跟踪系统的发展,目前运动目标的自动跟踪已经成为监控领域中最热门的话题之一,更重要的是,它的出现实现了从被动跟踪模式向主动跟踪模式的转变,并且通过对运动目标的计算和预测,能实现对运动目标的智能跟踪。论文首先研究了基于运动目标的识别和跟踪的算法。分析了在有运动目标存在的图像序列中目标的检测方法,确定了运动目标质心的求取方法,在这个基础上提取出了运动目标的模板,并把此模板应用于进一步的运动目标匹配与跟踪中。随后论文研究了基于TMS320DM642的运动目标自动跟踪系统的设计和实现。研究了TMS320DM642的性能特点,提出了以TMS320DM642为核心处理器的运动目标自动跟踪系统的硬件实现方案,并进行了论证。该硬件电路包括视频解码A/D、视频编码D/A、数据缓冲器、DSP、CPLD、UART、数据存储和FLASH等功能模块。本文详细介绍了运动目标自动跟踪系统中各个功能模块的硬件电路设计及系统时序的设计和实现。经过对所设计的系统的实际测试,软硬件性能均达到了实时性、可靠性和稳定性等指标。该课题已经成功的结题,各项指标均满足合作单位的要求。

【Abstract】 With the fast development of the society, the development of Target Tracking System is more and more mature. Target Tracking System, which plays an important role in the society, is widely used in various fields of military, industrial and commercial. The suggestion of intellectualization further accelerates the development of Target Monitor System. The Moving Target Auto-Tracking has become one of the most popular topics of monitoring field. What is more important, its appearance realized the transform from the passive tracking pattern to active tracking pattern. And Moving Target Auto-Tracking can become an intellectualized tracking via calculation and forecasting of Moving Target.The theory of moving target identifying and tracking is discussed in the first section. The methods of target detection are analyzed in sequence image which include moving target, and the calculation methods of mass center are introduced. Then, the template of moving target is abstracted out, which is applied in moving target matching and tracking.In the next section of this dissertation, the design and implementation of Moving Target Auto-Tracking monitor based on TMS320DM642 is studied. After analyzing the performance and characteristics of TMS320DM642, the implementation scheme of Moving Target Auto-Tracking monitor with TMS320DM642 as the core processor is put forward. The hardware of the system includes such function blocks as video decoder A/D, video encoder D/A, data buffer, DSP, CPLD, UART, data memory and FLASH. This dissertation introduces the hardware of every function block and the realization of system timing. According to the practical measurement of this system, the performance of both hardware and software all meet with such requirements as stability, reliability and real time etc. This project has successfully completed, and all its technical specifications are aligning with the requirements.
