摘要
介绍了一种以DSP(数字信号处理器)为核心处理芯片的数字式电视跟踪系统的设计。DSP主要实现视频图像的采集、预处理、二值化、目标识别、跟踪、预估等任务;而FPGA(现场可编程门阵列)主要实现实时的视频信息叠加和一些控制功能。在介绍系统硬件设计的基础上,分析了软件的任务模块和其实现方法,以及FPGA的主要功能。实验证明,本系统的性能高、扩展性强。
Digital TV tracking system based on the processing chip DSP is introduced. The function of DSP is to achieve collection, preprocessing, segmentation, target identification, tracking and estimation; and FPGA is used to overlap video signals and control. Introducing the hardware design first, the mission modules of the software and realization methods are analyzed, as well as the function of FPGA. The system is shown by experiments to have high performance and powerful expansibility.
