在 Windows 上使用 MinGW 使用 SFM 模块为 Android 编译 OpenCV
Compiling OpenCV for Android with SFM module using MinGW on Windows
我正在尝试使用 contrib 模块为 Android 编译 OpenCV，主要是我对 sfm 感兴趣。我做了很多研究，最后我做了以下以支持 sfm：
已编译的 gflags
编译日志
编译谷神星
之后我使用这个cmake命令构建并生成（下面给出了部分输出）：

我正在尝试使用 contrib 模块为 Android 编译 OpenCV，主要是我对 sfm 感兴趣。我做了很多研究，最后我做了以下以支持 sfm：
