-1、背景

Repository for OpenCV’s extra modules. Contribute to opencv/opencv_contrib development by creating an account on GitHub.即opencv-contrib是OpenCV额外模块（扩展模块）。
对应的是opencv /opencv_contrib
可以认为是opencv的增强版！

注意：商用的话，请留意相关算法是否涉及专利保护。

-2、尝试conda直接安装

conda install opencv-contrib-python

如上图，安装找不到相关的资源，目前直接使用清华镜像源安装不行！

-3、pip安装下载的whl文件

上图是安装找不到相关的资源，此时可以选择下载 whl的方式安装。
https://pypi.python.org/pypi/opencv-contrib-python
注意：PyPI这个网站可能需要VPN，不然特别慢，最近是基本上不去。
下面是我下载的opencv_contrib_python-4.2.0.34-cp37-cp37m-win_amd64.whl 如下图：
在这里插入图片描述
在终端安装如下：

如上安装成功了！
最后，在资源里，我将上传opencv_contrib_python-4.2.0.34-cp37-cp37m-win_amd64.whl
