Ubuntu14.04+anaconda2下配置opencv3

Ubuntu14.04+anaconda2下配置opencv3

1.opencv编译安装

# Get all the up-to-date tools you'll need

sudo apt-get update

sudo apt-get install git cmake build-essential

# Get latest greatest OpenCV from GitHub

git clone https://github.com/opencv/opencv.git

# Go build and install that puppy

cd opencv

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..（后面是一个空格加上两个点)

注：此时可能会提示cmake版本太低，则需要升级

make -j 8

sudo make install

2.在python中导入（没做这一步）

cp /usr/local/lib/python2.7/site-packages/cv2.so ~/anaconda2/lib/python2.7/site-packages

3. 最后，测试是否安装成功 

root@VB:# python 

>>>import cv2 

 >>>cv2.__version__ 

 '3.4.0' 

显示出版本号，则表示opencv安装成功。

在导入的时候可能会出现not found的错误，安装opencv-python即可解决：

pip install opencv-python

Ubuntu14.04 默认CMake版本是2.8.X 当我们需要更高级版本的时候就需要升级CMake。具体步骤如下： 

sudo apt-get install build-essential //如果系统已安装build-essential则不需要执行此步骤

wget http://www.cmake.org/files/v3.5/cmake-3.5.1.tar.gz

tar xf cmake-3.5.1.tar.gz

cd cmake-3.5.1

./configure

make

sudo apt-get install checkinstall

sudo checkinstall
