摘要
采用高帧频数字相机作为输入源，能够明显提高对小目标的跟踪精度和显示效果。文章介绍的系统以DSP，FPGA，CAN总线以及大容量缓存作为硬件构架，通过DSP和FPGA的逻辑编程灵活调配系统资源，将图像采集、图像处理、视频格式转换、通信控制、图像显示等功能合理分配至各个硬件单元。经过实验验证，该系统处理能力强，跟踪精度高，通信控制好，各个功能单元都达到了预期的效果。
A digital camera with high-frame-frequency is used for improving the tracking accuracy and the effect of displaying small targets. The hardware framework used by the system includs DSP, FPGA, CAN BUS and mass buffer storage, and the system resource is flexibly assigned through the logic programming of DSP and FP- GA. The image acquisition and processing, video format conversion, communication control and displaying function are properly distributed to each hardware unit. An experiment is made showing that the system has strong processing power, high tracking accuracy and good communication control capability. The expected effect of each function unit is achieved.
