摘　　要：由于红外地面弱小目标的检测与跟踪技术中,处理的数据量大,运算算法复杂,因此红外视频处理系统要求对数据信息有足够高的吞吐量和处理速度。DSP在数据的复杂算法运算处理方面有明显的优势,而FPGA更利于实现时序逻辑算法,所介绍的红外视频处理系统就将DSP模块作为核心处理器来完成红外地面弱小目标图像的检测与跟踪算法,FPGA模块则作为协处理器完成图像接收、预处理、时序控制等功能,FPGA控制ARM模块显示图像处理结果,形成高效处理图像数据的系统,该系统通过实践取得了较好的检测跟踪效果。Infrared video processing system has a sufficiently high throughput and processing speed of the request to the data information, because of the processing of large volumes of data and complex arithmetic algorithm in the infrared ground little target detection and tracking technology. DSP has a distinct advantage in the complex arithmetic operations of the data processing, while FPGA is more conducive to the realization of the temporal logic algorithm, so the infrared video processing system described in this article will be DSP module as the core processor to complete the image of infrared ground little target detection and tracking algorithms, FPGA module as a coprocessor to complete the image receiving, pre-processing, timing control function, FPGA controls the ARM module to display the results of the image processing, to form a highly efficient system for processing image data, this system achieved better detection and tracking results through practice.
