| 摘 要： | 介绍了Laplacian边缘检测算法模型，边缘检测工作流程，分布式运算原理，阐述了用FPGA实现的一个Lapla—cian图像边缘检测器的设计，包括系统总体设计，主要模块的设计思想和系统仿真结果。该检测器采用了流水式数据输入和高速分布式卷积运算等技术，具有良好的实时处理性能，若系统工作时钟为100MHz，则处理一幅1024-1024的图像的时间仅需0．01s左右。

| Abstract: | The model of Laplacian edge detection algorithm,the edge detection workflow and the principle of distributed arithmetic are introduced, and the implementation of Laplacian image edge detectior with FPGA is specified, which includes system architectures,main modules design and simulation results.The detector is adopted streamline data input technique and high-speed distributed convolution arithmetic,with good real-time performance.If the system clock is 100MHz,the detector only takes 0.01s to handle a 1024-1024＇s image. |
