opencv2\flann\logger.h(66): error C4996: 'fopen' 解决方法

Visual Studio 使用opencvc出现以下错误：

\opencv2\flann\logger.h(66): error C4996: ‘fopen‘: This function or variable may be unsafe. Consider using fopen_s instead. To disable deprecation, use _CRT_SECURE_NO_WARNINGS. See online help for details.

解决方法

在属性-->C++-->Preprocessor-->Preprocessor Definitions里加入 _CRT_SECURE_NO_WARNINGS即可
