摘要
红外目标跟踪方法的理论研究较多,而通用的实时跟踪系统较少。给出了具有CompactPCI总线、并行分布式结构的系统方案,核心是基于标准总线的实时系统,上位机实现卡尔曼预测,DSP并行完成频域转换与相关,CPLD实现总线接口控制。所实现的系统具有运算能力强、通信带宽大、可扩展性和通用性强的特点,实用表明了它的可行性。
The existing researches of infrared video tracking most focus on theory. The universal and real time tracking system was presented rarely. In this paper, a general purpose scheme of real time infrared video tracking system based on CompactPCI bus and parallel computer architecture is given. The kernel component is real time operation system of standard bus. PC is performed for Kalman filtering, DSP is employed to accomplish FFT transform and correlation parallel. CPLD is served to control CompactPCI bus bridge. The architecture has characteristics of strong computational capability, broad I/O bandwidth, and expansibility. The result of experiments indicate that this system works perfectly.
