关于c ++:Debug Assertion失败

Debug Assertion Failes

我正在编写一个C++代码,使用OpenCV集成在Visual Studio 2010中。我遵循本教程:

http://opencv-srf.blogspot.com/2013/06/load-display-image.html

但当我运行代码时,收到了以下错误消息:

这个报错程序:…文件:f:ddvctoolscrt_bldself_64_amd64crtsrcfopen.c线:54

表达式:(文件!=空)

有关程序如何导致断言的信息失败,请参阅断言上的VisualC++文档。

这是我的代码:

这里有两个问题:

  • 您的文件C:/Users/Ruaa/Pictures/aa.png不存在,您应该使用现有的文件进行尝试。
  • 使用opencv libs的调试版本,删除.lib/.dll文件末尾的d,如opencv_highgui245d=>opencv_highgui245,这将阻止断言,使其更快,并且很少需要在opencv内部进行调试。
