四月的筆記

1. 首先先安裝 OpenCV 

安裝路徑:

D:\Work\3_Install\1_Camera_Get\

 

 

 

 

 

 

 

 

 

 

 

 

 

2. 設定環境變數

在安裝路徑找到 bin的位置 :  .\Opencv\build\x64\vc16\bin

D:\Work\3_Install\1_Camera_Get\Opencv\build\x64\vc16\bin

 

 

 

 

 

 

在環境變數 設定 bin 的位置 :  .\Opencv\build\x64\vc16\bin

opencv16
D:\Work\3_Install\1_Camera_Get\Opencv\build\x64\vc16\bin

 

 

 

 

 

 

 

 

 

 

 

3.  開啟一個 C++ 的專案 

 

 

 

 

 

 

 

 

 

 

4. 環境配置

4.1 其他 include 目錄: 

.\Opencv\build\include

.\Opencv\build\include\opencv2

D:\Work\3_Install\1_Camera_Get\Opencv\build\include
D:\Work\3_Install\1_Camera_Get\Opencv\build\include\opencv2

 

 

 

 

 

 

 

 

 

4.2 其他程式庫目錄: .\Opencv\build\x64\vc16\lib

D:\Work\3_Install\1_Camera_Get\Opencv\build\x64\vc16\lib

 

 

 

 

 

 

 

 

4.3 其他相依:  在.\Opencv\build\x64\vc16\lib內的  opencv_world4100.lib

opencv_world4100.lib

 

 

 

 

 

 

 

 

5. Camera測試

#include <opencv2/opencv.hpp>
using namespace std;
using namespace cv;



void Color_Cout(Mat frame,int Select_color1)
{
    for (int i = 0; i < frame.rows; i = i + 10)
    {
        for (int j = 0; j < frame.cols * 3; j = j + 3 * 10)
            cout << (int)frame.at<unsigned char>(i, j + Select_color1) << " ";
        cout << endl;
    }
    cout << endl << endl;
}




int main() {

    Mat frame0;
    VideoCapture cap0(0);
    if (!cap0.isOpened()) {
        cout << "Cannot open camera 0 \n";
        return 1;
    }



    int Camera_Number = 0;
    while (true) 
    {
        bool ret0 = cap0.read(frame0);
        if (!ret0) 
        {
            cout << "Can't receive frame 0 (stream end?). Exiting ...\n";
            break;
        }
        imshow("live", frame0);

        int WK = waitKey(1);
        if (WK == 'q')
        {
            break;
        }
        else if (WK == 's')
        {
            cout << "Camera Size:" << frame0.total() << endl;
        }
        else if (WK == 'd')
        {
            int R_color1(2), G_color1(1), B_color1(0);
            Color_Cout(frame0, R_color1);
            Color_Cout(frame0, G_color1);
            Color_Cout(frame0, B_color1);
        }
    }

    return 0;
}

 

6. DLL的位置

在安裝路徑找到 bin的位置 :  .\Opencv\build\x64\vc16\bin

將DLL都丟進去
