原创-EMGUCV的模板匹配与跟踪完成啦.doc

原创-EMGUCV的模板匹配与跟踪完成啦！兄弟们好！经过很多天的努力学习，我的EMGUCV的模板匹配完成了，用实际的摄像头取图象，再存为模板后，就能实现物体跟踪，还能进行相机上马达进行位置确定。好玩吧！弄两幅图来看下。这是匹配的，还能过行坐标二次定位。坐标二次定位的这是跟踪的以下为代码，只有自己写的部分，由软件生成的部分没有帖上using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Threading;using System.IO;using System.Drawing.Imaging;using Emgu.CV;using Emgu.CV.Structure;using Emgu.CV.CvEnum;using Emgu.CV.Util;using Emgu.CV.UI;using Emgu.CV.VideoSurveillance;using Emgu.Util;using Emgu.Util.TypeEnum;using Emgu.CV.GPU;namespace 模板匹配 public partial class Form1 : Form public Image src;
