qt opencv无法读取图像

Question

我是qt创建者的新手，我对它的构建错误和未定义错误的基调感到厌烦。最后，我毫无错误地安装了opencv3.2。Noti可以使用opencv库，但是我不能读取像"image.jpg“这样的文件。我什么都试过了。路径是%100正确的斜杠是正确的。在cmake安装过程中没有错误。请帮我一把:D

LIBS += C:\opencv3.2\build\bin\libopencv_core320.dll
LIBS += C:\opencv3.2\build\bin\libopencv_highgui320.dll
LIBS += C:\opencv3.2\build\bin\libopencv_imgcodecs320.dll
LIBS += C:\opencv3.2\build\bin\libopencv_imgproc320.dll
LIBS += C:\opencv3.2\build\bin\libopencv_features2d320.dll
LIBS += C:\opencv3.2\build\bin\libopencv_calib3d320.dll

try {
     Mat image = imread("D:\\Adsız.jpeg",0);
     if (!image.data)
         cout << "Data is empty" << endl;
    
     namedWindow("My image");
     imshow("My image",image);
     waitKey();
} catch (const exception& e) {

}

输出

10:50:24: Starting C:\Users\YUNUS EMRE\Qt Workspace\build-OpenCVTest-Desktop_Qt_5_15_0_MinGW_32_bit-Release\release\OpenCVTest.exe ...
Data is empty

它返回空图像。

我通过安装Opencv 4.4.0解决了这个问题。这是一个有点难安装，但我弄明白了，谢谢你的回复。
