Open CV (5) 使用Windows Form - PictureBox 顯示影像

在pictureBox顯示影像。

1. 在視窗中增加 PictureBox、Button、Timer控制項，之後再使用滑鼠快按兩下"button1"。

2. 輸入範例程式，最後按"開始偵錯"按鈕進行編譯。

stdafx.h

1 2	#include <cv.h> #include <highgui.h>

Form1.h

1 2 3 4 5 6 7 8 9 10 11 12 13

namespace test {     using namespace System;     using namespace System::ComponentModel;     using namespace System::Collections;     using namespace System::Windows::Forms;     using namespace System::Data;     using namespace System::Drawing;     using namespace cv; //add source code     CvCapture* capture; //add source code     IplImage* frame; //add source code

1 2 3 4 5 6 7 8 9 10 11

private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) {              capture = cvCaptureFromCAM(0);              timer1->Start();          } private: System::Void timer1_Tick(System::Object^  sender, System::EventArgs^  e) {              frame = cvQueryFrame(capture);              pictureBox1->Image = gcnew                  Bitmap(frame->width,frame->height,frame->widthStep,                  Imaging::PixelFormat::Format24bppRgb,(System::IntPtr) frame->imageData);          }

3. 執行結果。
