摘　　要：兼顾电视跟踪器在实时性和稳定跟踪两方面的要求,设计了一种基于DSP的跟踪测量电视平台.系统主要利用模拟电视信号输出特点,在电视场周期内完成目标及背景图像数据的采集;利用FIFO作为图像数据缓冲器,设计DSP与其接口完成对数据的快速读取及目标位置计算.该系统经工程验证,能够快速捕获目标并实现目标稳定自动跟踪.In order to satisfy requirements of real-time and stability for the television tracker, a tracking television system based on DSP is introduced. Using the output characteristics of the analog video signal, the image of object and background acquisition in television field period is completed. FIFO also is used as an image buffer, and the interface between DSP and FIFO is designed in the system, which could make the image data read fast and calculate the object position.
