ubuntu14.04下安装OpenCV 3.0 +Python 2.7

配置环境:

• ubuntu14.04
• python2.7
• opencv3.0

---

1、准备工作

更新apt-get

sudo apt-get update
sudo apt-get upgrade

安装pkg-config、cmake、git

sudo apt-get install build-essential cmake git pkg-config

安装图片I/O包

sudo apt-get install libjpeg8-dev libtiff4-dev libjasper-dev libpng12-dev

安装GTK开发库用于图片的显示

sudo apt-get install libgtk2.0-dev

安装处理视频流的包

sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev

安装用于优化OpenCV的库

sudo apt-get install libatlas-base-dev gfortran

安装pip

wget https://bootstrap.pypa.io/get-pip.py
sudo python get-pip.py

安装python2.7

sudo apt-get install python2.7-dev

安装Numpy

sudo pip install numpy

2、安装OpenCV3.0

从github上下载OpenCV3.0

cd ~
git clone https://github.com/Itseez/opencv.git
cd opencv
git checkout 3.0.0

从github上下载opencv_contrib

cd ~
git clone https://github.com/Itseez/opencv_contrib.git
cd opencv_contrib
git checkout 3.0.0

注意：opencv的版本与opencv_contrib的版本必须一致

配置编译文件

cd ~/opencv
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE \
      -D CMAKE_INSTALL_PREFIX=/usr/local \      
      -D INSTALL_C_EXAMPLES=ON \      
      -D INSTALL_PYTHON_EXAMPLES=ON \      
      -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules \     
      -D BUILD_EXAMPLES=ON ..

如果cmake过程中提示：ippicv_linux_20141027.tgz的hash码不对，则将下载的ippicv_linux_20141027.tgz手动复制到 opencv-3.0.0-beta/3rdparty/ippicv/downloads/linux-8b449a536a2157bcad08a2b9f266828b文件夹中，重新cmake即可
下载链接：ippicv_linux_20141027.tgz

注意：若在Ubuntu16.04下安装了Nvidia显卡CUDA8.0驱动需要cmake时添加

-D WITH_CUDA=OFF 

否则编译的过程中会报以下错误：

make[2]: *** [modules/cudalegacy/CMakeFiles/opencv_cudalegacy.dir/src/graphcuts.cpp.o]

编译OpenCV

make -j4

编译完成后就可以安装了

安装OpenCV

sudo make install
sudo ldconfig

3、验证

打开命令行

python
>>> import cv2
>>> cv2.__version__
'3.0.0'

如果可以正确显示OpenCV的版本信息则说明安装成功
