一些背景知识
opencv1.1已经不再维护目前只能从github中找到一个历史的版本: https://github.com/archith/opencv_1.1opencv2.x 3.x 4.x 5.x 都有完善的cmake编译脚本编译起来都比较容易。参考我前一篇博客opencv2.x 中含有nonfree的模块比如surfsirf。这部分代码在后面的仓库中被移动到 opencv_contrib 中。https://opencv.org/releases/ 中提供的库都没有包含nonfree的模块如果需要使用nofree的模块需要自己拉代码下来编译。一些基于release做二次处理的库比如https://github.com/nihui/opencv-mobile 也是没有包含nonfree的模块。
