摘　　要：FPGA在高速图像处理中具有结构灵活、通用性强等特点,针对交通监控系统对复杂交通场景中监控图像处理的实时性要求,提出了以FPGA芯片为平台,利用FPGA丰富的逻辑资源,结合用户自定义外设,组建一个在模块级和组件级定义的系统,分别设计了图像采集、存储和实时预处理模块,实现了交通监控图像的高速预处理.FPGA has many characteristics in the high-speed image processing, such as flexible structure, strong compatibility and so on. According to the real-time requirements of the monitoring image processing in complex traffic scene for the traffic monitoring system,a system defined between module and componet level has been established with abundant logical resources of FPGA and customized peripherals in the phase of image pretreatment. The modules of image acquisition, image storage and real-time pretreatment have been designed and the high-speed pretreatment of traffic monitoring image in the front has been realized.
