1）下载适用于 windows 的 opencv 安装包。OpenCV下载页面：<a href="http://sourceforge.net/projects/opencvlibrary/files/opencv-win/" style="color: rgb(0, 68, 153); text-decoration: none;" target="_blank">http://sourceforge.net/projects/opencvlibrary/files/opencv-win/</a><br>
2）直接下载 <a href="http://sourceforge.net/projects/opencvlibrary/files/latest/download?source=files" style="color: rgb(0, 68, 153); text-decoration: none;" target="_blank">OpenCV-2.4.5.exe (278.9 MB)</a></p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);">安装。你会发现实际上就是解压缩的过程。</p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);"> </p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);">二、Python<br>
1）下载适用于 windows 的Python安装包。Python下载页面：<a href="http://www.python.org/getit/" style="color: rgb(0, 68, 153); text-decoration: none;" target="_blank">http://www.python.org/getit/</a><br>
直接下载 <a href="http://www.python.org/ftp/python/2.7.5/python-2.7.5.msi" style="color: rgb(0, 68, 153); text-decoration: none;" target="_blank">Python 2.7.5 Windows Installer </a><br>
2）安装。<br>
3）扩展Python的第三方库——OpenCV的python库<br>
进入OpenCV的安装目录下找到：\build\python\2.7\cv2.pyd<br>
将cv2.pyd复制到Python的子目录下：\Lib\site-packages\</p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);"> </p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);">OK，至此环境就搭建好了。</p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);"> </p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);">三、测试示例程序<br>
OpenCV自带了很多示例程序，进入OpenCV安装目录下的子目录：\samples\python2\ ，可以看到很多以.py为后缀名的文件；<br>
用python随便打开一个.py文件，按F5键运行，看看效果</p><p style="margin: 0px; padding: 5px 0px; line-height: 22px; color: rgb(51, 51, 51); font-family: 'Microsoft YaHei', Tahoma, Arial; font-size: 14px; background-color: rgb(255, 255, 255);"> </p><br></div>
