apt-get 安装opencv2

sudo apt-get install libcv-dev

1sudoapt-getinstalllibcv-dev

apt-get安装Python cv2扩展

sudo apt-get install python-opencv

1sudoapt-getinstallpython-opencv

测试一下cv2模块是否可以加载：

$ python

Python 2.7.6 (default, Oct 26 2016, 20:30:19)

[GCC 4.8.4] on linux2

Type "help", "copyright", "credits" or "license" for more information.

>>> import cv2

>>>

>>>importcv2

>>>

OK

上面的自动安装好像是不完整的，我在导入cv2进行人脸识别等功能处理的时候，return空，等于是没反应。我查看了一下，人脸识别等用到的分类器等东东，系统中没有。那么仍旧需要源码安装opencv3，那么：

1、官网下载opencv3.0.0

http://opencv.org/releases.html

各种版本，我Ubuntu14.04选择的opencv3.0.0，约100M，推荐迅雷下载，wget很慢。

2、下载完解压缩，进入目录

cmake .

1cmake.

3、cmake过程中需要自动下载ippicv_linux_20141027.tgz，但命令行自动下载后，可能会提示【ICV hash校验值不符】，cmake中断退出

解决方法：手动下载ippicv_linux_20141027.tgz，覆盖出错自动下载文件。下载地址：https://sourceforge.net/projects/opencvlibrary/files/3rdparty/ippicv/，覆盖地址：opencv-3.0.0/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b/ippicv_linux_20141027.tgz

覆盖完，再次执行cmake .即可

4、编译

make

1make

请耐心等待，大约二十分钟。

5、安装

sudo make install

1sudomakeinstall

安装完成后，会看到安装列表中有想要的各种识别分类器：

这些分类器xml的地址未来需要被识别脚本.py文件引用。

6、配置

sudo vim /etc/ld.so.conf.d/opencv.conf

#添加一行：/usr/local/lib

#添加一行：/usr/local/lib

sudo vim /etc/bash.bashrc

#添加以下两行

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig

export PKG_CONFIG_PATH
