OpenCV(4.4.0) Error: Assertion failed (size.width＞0 && size.height＞0) in cv::imshow, file C:\build\m

出现错误

OpenCV(4.4.0) Error: Assertion failed (size.width>0 && size.height>0) in cv::imshow, file C:\build\master_winpack-build-win64-vc15\opencv\modules\highgui\src\window.cpp, line 376

1.检查路径是否改为将“\”改为“\\”或“/”

如：E:\s\a.png 改为 E:\\s\\a.png

2.检查路径中是否有中文

3.将 属性->连接器->输入->附加依赖项 中的 opencv_world440.lib删除，只保留opencv_world440d.lib

因为在debug环境下会出错
