MYLAF 环境说明 

编程环境：Windows 10(64bit), VS2013, OpenCV 2.4.12; 

编程语言：C/C++；

MYLAF 现象 

在代码中，调用imread读取图片失败，但调用cvLoadImage读取成功。

MYLAF 代码

// MYLAF #include "opencv2/opencv.hpp"using namespace std; using namespace cv; int main() { Mat im = imread("D:\\imgSrc.png");// IplImage* img = cvLoadImage("D:\\imgSrc.png"); if (img) { im = img; } imshow("orig",im); waitKey(0); return 0; }

MYLAF 原来如此 

OpenCV的imread，imshow等等这些函数在编译链接时是认主的，特别忠心不二。 

用人话来说就是：如果你使用Debug模式编译链接，那么请链接Debug模式(opencv_*2412d.lib等)库文件；如果你使用Release模式编译链接，那么请链接Release模式(opencv_*2412.lib)等库文件。 

否则，你就自己玩去吧。 

MYLAF 解决 

在“VS项目–属性–链接器–输入–附加依赖项”添加与项目配置Configuration相对应的lib文件。 

或者使用如下类似代码进行指定对应的lib文件

#if _DEBUG // _DEBUG=Debug模式#pragma comment(lib, "opencv_core2412d.lib")#else // NDEBUG=Release模式 #pragma comment(lib, "opencv_core2412.lib") #endif
