本文主要根据以上博主的文章,在其基础上将其改为用MFC界面实现,效果图如下
功能实现如下:点击打开深度相机按钮,可以启动kinect相机,然后在左边框图中进行显示,骨骼检测得到的图在右边框图实现。代码链接:这里写链接内容
1.打开visual studio 新建MFC工程
2.点击下一步,然后选择单文档对话框,再点击下一步
3.点击下一步,去掉勾选粗框架和系统菜单,再点击创建完成就可以了
4.此时界面如图
5.删除TODD:在此放置对话框控件,同时删除取消按钮,保留确定按钮,并将确定按钮选择Caption 重新命名为close
6.找到工具箱,添加一个Button ,一个Caption命名为打开深度相机,然后在工具箱中找到picture Control控件,添加两个到我们的界面,一个ID号重新命名为 IDC_ColorImage ,另外一个命名为IDC_STATIC。 同时可以适当将界面拉大一点,然后在工具箱中找到Static Test 空间,添加两个到界面,一个为深度图像显示,一个为骨骼检测显示,此时界面如图:
7. 现在开始添加代码 ,首先添加opencv的头文件,我是放在bonetestDlg.h中,
#include "Kinect.h"
#include "afxwin.h"
#include
bonetestDlg.cpp添加头文件如下
#include "stdafx.h"
#include "bonetest.h"
#include "bonetestDlg.h"
#include "afxdialogex.h"
#include
#include "cv.h"
#include //opencv头文件
#include
#include
using namespace cv;
using namespace std; //命名空间
//--------------------------与Kinect有关-----------------------//
void CbonetestDlg::OnBnClickedOpenKinect()
{
HRESULT hr = myKinect.InitializeDefaultSensor(); //初始化默认Kinect
if (SUCCEEDED(hr))
{
myKinect.Update(); //刷新骨骼和深度数据
}
SetTimer(35, 20, NULL); //定时器
}
void CbonetestDlg::OnTimer(UINT_PTR nIDEvent) //定时器处理
{
switch (nIDEvent)
{
case 35:
myKinect.Update();
default:
break;
}
CDialog::OnTimer(nIDEvent);
}
注意:必须在下面这段程序中添加定时器事件
BEGIN_MESSAGE_MAP(CbonetestDlg, CDialogEx)
ON_WM_PAINT()
ON_WM_TIMER() //定时器事件
ON_WM_QUERYDRAGICON()
ON_BN_CLICKED(IDC_OPEN_KINECT, &CbonetestDlg::OnBnClickedOpenKinect)
ON_BN_CLICKED(IDOK, &CbonetestDlg::OnBnClickedOk)
ON_STN_CLICKED(IDC_ColorImage, &CbonetestDlg::OnStnClickedColorimage)
END_MESSAGE_MAP()
9.自己创建kinect.h和kinect.cpp程序
//kinect.h
#pragma once
#include
#include "cv.h"
#include //opencv头文件
#include
#include
using namespace cv;
using namespace std; //命名空间
template<class Interface>
inline void SafeRelease(Interface *& pInterfaceToRelease)
{
if (pInterfaceToRelease != NULL)
{
pInterfaceToRelease->Release();
pInterfaceToRelease = NULL;
}
}

{
public:
static const int cColorWidth = 1920;
static const int cColorHeight = 1080;

~CBodyBasics();
friend class CSerialPortTestDlg;

//void updataToSurface(Mat &img );
void draw(Mat & img, Joint & r_1, Joint & r_2, ICoordinateMapper * myMapper);//画线跟圆

10,重要的一点,
在kinect.cpp中显示图像到MFC上,
在bonetestDlg.h中定义一个静态变量:
static CbonetestDlg *s_pDlg; //对象指针
在bonetestDlg.cpp初始化:
CbonetestDlg * CbonetestDlg::s_pDlg = nullptr;
在 CbonetestDlg 消息处理程序中加上这句话s_pDlg = this;
BOOL CbonetestDlg::OnInitDialog()
{
CDialogEx::OnInitDialog();
SetIcon(m_hIcon, TRUE); // 设置大图标
SetIcon(m_hIcon, FALSE); // 设置小图标
s_pDlg = this; //很重要的一句话 , 对话框的指针 , 用于与Kinect 类交互
return TRUE; // 除非将焦点设置到控件,否则返回 TRUE
}
这样基本功能就实现啦,这算我学了c++之后入手的第一个程序,调了两三天,才一点点的明白一个程序,怎样照葫芦画瓢,一味的照搬过来的话实现不了,程序还一大堆的bug,这里改好了那里又出问题了自己还要多多总结,还是需要积累经验。(中间男票帮我看了一下,分分钟他就搞定了,这就是差距,泪奔)。
