PIE SDK与OpenCV结合说明文档

第一步

利用PIESDK写一个Command类，本文是OpenCVTestCommand.cs

其类继承PIE.Framework.DesktopCommand;

第二步

重写OnClick()方法进行调用OpenCV例子生成的的exe

第三步

PIESDK命令调用(PIEApplication.xml配置或者ICommand调用)，本文采用的是ICommand调用

接口/类

方法

说明

PIE.SystemUI.ICommand

OnClick

单击事件

OnCreate

绑定地图对象

示例代码

 1 在PIE SDK调用时的写法 新建OpenCVTestCommand命令类

 3 using System;
 4 using System.Collections.Generic;
 5 using System.Diagnostics;
 6 using System.Linq;
 7 using System.Text;
 8 using System.Threading;

10 namespace OpenCVMapApplication
11 {
12     /// <summary>
13     /// PIESDK和Opencv结合命令
14     /// </summary>
15     class OpenCVTestCommand : DesktopCommand
16     {
17         /// <summary>
18         /// 构造函数
19         /// </summary>
20         public OpenCVTestCommand()
21         {
22             this.Caption = "OpenCVTestCommand";
23             this.Name = "OpenCVTestCommand";
24         }
25 
26         /// <summary>
27         /// 单击事件
28         /// </summary>
29         public override void OnClick()
30         {
31       string exe_path = @"E:\Software\PIE示例教程\PIE示例数据\图片\OpencvTest.exe";// 执行调用exe路径
32    string[] the_args = { @"E:\Software\PIE示例教程\PIE示例数据\OpenCV文件\window7.png" };// exe执行的参数
33             bool result = StartProcess(exe_path, the_args);
34             if (result == false)
35             {
36                 System.Windows.Forms.MessageBox.Show("执行失败！");
37             }
38         }
39        /// <summary>
40        /// 进程调用
41        /// </summary>
42         /// <param name="exePath">exe执行程序调用</param>
43        /// <param name="args">参数</param>
44        /// <returns></returns>
45         public bool StartProcess(string exePath, params string[] args)
46         {
47             string s = "";
48             foreach (string arg in args)
49             {
50                 s = s + arg + " ";
51             }
52             s = s.Trim();
53            Process process = new Process();//创建进程对象    
54             ProcessStartInfo startInfo = new ProcessStartInfo(exePath, s); // 括号里是(程序名,参数)
55             process.StartInfo = startInfo;
56             process.Start();
57             return true;
58         }
59     }
60 }
61 注意：
62 OpenCVTestCommand.cs主要是调用opencv生成结果文件OpencvTest.exe;
63 最后一步如何在PIE搭建的程序调用OpenCVTestCommand命令呢？
64 首先在PIE搭建的界面上创建一个按钮，点击按钮的Click事件为toolStripButton_LoadOpenCV_Click
65         /// <summary>
66         /// 调用OpenCV例子
67         /// </summary>
68         /// <param name="sender">事件触发器</param>
69         /// <param name="e">事件参数</param>
70         private void toolStripButton_LoadOpenCV_Click(object sender, EventArgs e)
71         {
72             ICommand command = new OpenCVTestCommand(); //调用命令
73             command.OnCreate(mapControlMain);
74             command.OnClick();
75         }
