【摘要】：目标跟踪技术是电视导引头的关键技术,同时也是计算机视觉等领域的研究热点。本文的主要研究内容为低成本电视导引头的目标跟踪器以及导航信息的随屏显示技术。主要进行了以下工作：首先设计了基于单片机、字符叠加器和DSP芯片TMS320DM642的目标跟踪和随屏显示系统的硬件平台。其中,DM642作为核心处理器来实现图像跟踪算法,单片机和专用的字符叠加芯片用来实现导航信息的随屏显示。然后,对相关匹配跟踪算法进行了研究,并将其应用在DM642上,完成了基于DM642的视频采集与显示程序、图像跟踪程序以及UART串口数据传输等程序设计。为实现目标位置、跟踪状态、跟踪框和十字线等导航信息的实时随屏显示,设计了用于导航信息的专用字库、单片机和字符叠加器的SPI通信程序、串口通信程序以及导航信息随屏叠加程序等软件。最后,对系统硬件平台的各功能模块进行了测试。通过对一个运动的模型小车做图像跟踪实验,验证了系统的可行性。实验结果表明,本文中设计的目标跟踪和随屏显示系统能够正确完成目标跟踪以及导航信息随屏显示工作,为低成本电视导引头的工程应用打下了基础。
[Abstract]:Target tracking is the key technology of TV seeker. At the same time, it is also a research hotspot in computer vision. The main content of this paper is the target tracker of low cost TV seeker and the display technology of navigation information. The main work is as follows:. Firstly, the hardware platform of target tracking and display with screen system based on single chip microcomputer, character superposition and DSP chip TMS320DM642 is designed, in which DM642 is used as the core processor to realize image tracking algorithm. Single-chip microcomputer and special character superposition chip are used to display navigation information with screen. Then, the correlation matching tracking algorithm is studied, and it is applied to DM642. The video acquisition and display program based on DM642, image tracking program and UART serial port data transmission program are completed. Tracking status, real-time display of navigation information such as tracking frame and cross line, design of special font library for navigation information, SPI communication program of single chip computer and character superposition, etc. Serial communication program and navigation information with screen superposition program and other software. Finally, the functional modules of the hardware platform of the system are tested, and the feasibility of the system is verified by an image tracking experiment of a moving model car. The target tracking and on-screen display system designed in this paper can correctly complete the target tracking and navigation information display with the screen, which lays the foundation for the engineering application of low-cost TV seeker.
