Question

当我尝试在 Visual Studio 2010 中从 here 运行此代码时.我收到以下错误

OpenCV Error: Assertion failed ((img.depth() == CV_8U || img.depth() == CV_32F)
&& img.type() == templ.type()) in cv::matchTemplate, file ..\..\..\..\opencv\mod
ules\imgproc\src\templmatch.cpp, line 249
An exception occured

您似乎没有成功加载图像。因此，请确保通过设置 argv[] 正确传递图像。注意以下几行代码:

   if(argc <= 1)  
      {  
      std::cout<<"\n Help "<<std::endl;  
      std::cout<<"\n ------------------------------------\n"<<std::endl;  
      std::cout<<"./blink_detect open_eye.jpg close_eye.jpg\n"<<std::endl;  
     std::cout<<"Eg :: ./blink_detect 2.jpg 3.jpg\n"<<std::endl;  
      std::cout<<"\n ------------------------------------\n"<<std::endl;  
      exit(0);  
      }   
    ... ...
    img1 = imread( argv[1], 1 );  
    img2 = imread( argv[2], 1 );

编辑:您可以通过两种方式设置argv[]:

1. 通过项目的命令参数:

   项目 > 配置属性 > 调试 > 命令参数 > 2.jpg 3.jpg

2. 直接在源代码中:

   argc = 3;
   argv[1] = "2.jpg";
   argv[2] = "3.jpg";
