摘　　要：针对图像处理系统计算量大、实时性高和体积小的要求,研制了一种以DSP为主处理器FPGA为辅处理器的高性能实时图像处理系统。利用这两种芯片的各自特点,将算法分成两部分分别交由FPGA和DSP处理,大大提高了算法的效率。系统具有结构简单易于实现和运用方便灵活的特点,加载上相应的程序之后能实现对所获取的图像跟踪、识别和匹配等处理方法。详细说明了系统的设计思路和硬件结构,并在硬件系统上进行了算法仿真及实验验证。实验结果表明:该系统实时性高,适应性好,能够满足设计要求。Aiming at the requirements of a large amount of calculation,high real time and small volume of image processing system.The author developed a real time image processing system based on FPGA and DSP.Making use of the characteristics of both chips,the algorithm is divided into two parts processed by the FPGA and DSP respectively,thus greatly enhancing the efficiency of the algorithm.The System is of simple structure,easy to implement and with characteristics of convenient and flexible appliance,it can achieve image processing methods,such as tracking,recognizing and matching the obtained image.The thesis illustrated the design idea of the system and structure of the hardware.Moreover,in order to validate the system,we run some algorithm simulation on the hardware system,the result of which indicated that this system is of perfect real time performance and flexibility,and is able to meet the design requirements.
