摘　　要：为了提高光电跟踪系统的目标探测精度和系统响应速度,采用基于Camera Link接口的高清高帧频数字相机作为目标传感器,以DSP+FPGA作为核心处理器,采用目标二次提取法设计出高帧频视频跟踪器;此视频跟踪器结合DSP和FPGA在数据处理上的优势,将图像跟踪算法进行分解,FPGA通过硬件方式并行流水实现图像采集、图像预处理、图像存储、目标一次提取粗定位、图像叠加与显示等功能,DSP完成对目标二次准确提取;经实验验证,各功能单元达到预期效果,所设计的视频跟踪器图像处理能力强,满足实时、高精度的要求。In order to improve the target detection accuracy and system response speed,a high definition and high frame rate digital camera based on Camera Link interface is used as the target sensor,which uses the DSP ＋ FPGA as the core processor,A high frame rate video tracker is designed by using the two-time extraction method. This video tracker combines the advantages of DSP and FPGA in data processing,decomposing the image tracking algorithm. FPGA,through the hardware parallel pipeline,achieves image acquisition, image preprocessing, image storage, first target extracting coarse positioning, image superposition and display functions,DSP is used to finish second time accurate extraction of the target.Experiment proves that the functional units can achieve the desired effect,and the designed video tracker has the strong image processing ability,and can achieve the trait of real time and high precision.
