摘要： 为了能够实时地检测弹性体工件的缺陷和尺寸,设计并实现了一种基于处理器局部总线(PLB)的视频预处理IP核。对IP核所采用的结构、卷积运算的硬件实现进行研究。用System Generator工具设计LOG滤波器,最终在现场可编程门阵列(FPGA)上实现边缘检测算法。实验结果表明:与传统用软件实现边缘检测算法的方法相比,用IP核实现时间大幅减少,仅为40ms,满足弹性体工件在线检测系统中实时预处理视频的要求。

Abstract: In order to inspect the size and defects of elastomer workpiece in real-time, a video preprocessing IP core based on Processor Local Bus (PLB) was proposed and implemented. The structure of IP core and the hardware implementation of convolution were investigated. LOG filter was designed by System Generator, and ultimately the edge detection algorithm was implemented on Field Programmable Gate Array (FPGA). The experimental results indicate that compared to the traditional implementation of edge detection by software, method of IP core achieves higher speed, and needs only 40ms. It can satisfy the requirement of online inspection system of elastomer workpiece in real-time video preprocessing.

Key words: Field Programmable Gate Array (FPGA), IP core, online inspection, video preprocessing, edge detection
