本程式適合vs2017,其他版本需要修改標頭檔案。

Mat類矩陣初始化：1、直接初始化。2、利用陣列初始化。

1、    Mat cameraMatrix = (Mat_<double>(3, 3) << 1000, 0, 320, 0, 1000, 240, 0, 0, 1);//矩陣直接初始化

2、    double a[5][1] = { 1.0,0.01,-0.001,0,0 };//矩陣通過陣列進行初始化
    Mat distCoeffs = Mat(5, 1, CV_64F,a);

cout中空格可用 cout<<"a"<<a<<""<<"b"<<b<<endl;其中endl相當於換行；

printf的用法：printf("a=%d,b=%d/n",a,b);
