【摘要】 红外视频动目标的检测跟踪是图像处理应用的一个重要领域。在计算机视觉、交通监控、可视预警、导航等诸多民用领域有着广泛的应用，同时在导弹电视制导等军用领域也发挥着重要作用。本论文所研究的感兴趣区域的动目标检测跟踪等技术，在第三代图像压缩技术中的视频信息检索等领域也都有着重要的应用。本论文首先根据系统的实时性特点，将系统分成四个基本的状态：搜索、捕获、跟踪和记忆。依照状态机制的激励和转换条件，实现四个状态的转换运行，从而达到动目标的实时检测与跟踪的目的。针对实际系统要求，进行了硬件和软件总体设计，并且讨论了系统硬件的各个功能模块和软件结构化分层设计。通过建立的动目标检测跟踪系统方程，探讨系统实现的关键技术，并且针对我们所要处理的红外视频图像序列的具体特点，我们提出基于背景运动估计和补偿的动目标检测跟踪关键技术。然后进一步研究了系统的四个基本状态的具体实现方案和技术路线，实现和分析四个状态模块的PC仿真系统和C6x系统，并给出了系统状态运行结果。论文最后研究了该系统的C6x技术实现及分析了实现的C6x系统数据流。本系统对相关研究所提供的多维图像数据进行交付性的试验，取得了良好的结果。系统实际的成功性实验也表明本论文提出的理论、技术及具体的实现设计是成功的。更多还原

【Abstract】 Infrared Video Target Detection and Tracking System plays a great role in the field of digital image processing, and is widely used in civil and military affairs. The moving target detection techniques on the region of interesting (ROI) discussed in this dissertation can be also applied in image compression, information retrieval and interaction control by ROI.According to the real-time feature of this tracking system, it is divided into four states: search, capture, track and memory, and the states transition is fulfilled in the condition of the excitation of input and transition condition. According to system requirement, we design hardware and software system as a whole, and also discuss all modular functions of hardware system and software system architecture design at details. Through establishing the equation of moving target detection and tracking system, we find out the methods to solve the equation, and from the methods we come to discuss several crucial techniques of the implementation of system, and also according to the feature of the infrared video image sequence which we are processing and analyzing, we bring forward moving target detection and tracking technology based on background moving estimation and compensation.And then we go further into the implementation plan and technological path of the four fundamental states of this system, implement and analyze these four state model blocks on the PC simulation system and C6x system, also present the results.At last we discuss the DSP implementation of this system and analyze the data flow of DSP implementation. We have done the related experiments on the video sequences, which were provided by the relevant institute. The results of our experiments show that the system designed is correct, the key technologies have been implemented successfully in practical system and the design of system hardware and software is successful too.更多还原
