摘要
为解决目前电视跟踪系统体积庞大、结构复杂、系统兼容性差等问题,设计了一种集视频处理、云台运动控制、摄像机自动调节于一体的实时跟踪系统。系统采用双DSP处理器结构,把数据处理和系统控制分开;并将图像预处理、DPRAM实现、I2C总线逻辑以及字符叠加等功能集成在一片FPGA中实现;直接用户接口(DUI)功能可使系统脱离上位机独立进行工作。程序采用模块化设计,便于系统升级和其他算法的嵌入,使之亦可作为不同跟踪算法的测试平台。多次外场实验表明,该系统速度快,兼容性强,性能稳定,能满足各种不同现场的要求。
In order to resolve the problems of huge cubage, bed oompatibiliw and oomplex structure in the present real-time television tracking system, a new one is designed, in which two DSPs are used in order to ,detach data processing function from system oontrolling function; and many other functions such as image preprocessing, DPRAM memory, I^2C bus, character displaying, are realized in one FPGA chip. The system can work independently through the Direct User Interface （DUI）. In the program design, module is designed to be oonvenient for system upgrading and embedding of other algorithms, so it can be used as a testing platform for different tracking algorithms. The field experiments show that the system has the virtues of fast computing speed, good compatibility and stability, so that it is able to fill the needs in different field.
