边缘检测对于图像理解、目标检测、跟踪等问题非常重要，该代码实现了canny算子做边缘检测-Edge detection for image understanding, target detection, tracking a very important issue, the code implementation of the canny edge detection operator to do

此文件为delphi写的Canny算子边缘检测代码，只是一段代码。-This document is written in delphi Canny operator edge detection code, just a piece of code.

本代码主要使用了canny算法进行边缘检测，然后二值化，接着用cvFindContours搜索轮廓，最后从找到的轮廓中根据角点的个数，角的度数和轮廓大小确定，矩形位置-License Plate Recognition

双目相机与计算机连接后进行拍照，图片抓取，视频拍摄，人脸检测，Canny边缘检测，BM算法与SGBM算法进行立体匹配测距的实现。(The binocular camera is connected with the computer to take pictures, capture pictures, take videos, detect faces, Canny edge detection, BM algorithm and sgbm algorithm for stereo match
