OpenCV 已经发布到了3.0版本，最近Python也发布了3.5，之前的应用都还是基于 OpenCV 2.X 和 Python 2.7。

Ubuntu 14.04 64bit

Python3.4 应该已经像2.7一样是标配了。首先需要的是 pip：

sudo apt-get install python3-setuptools python3-dev
sudo easy_install3 pip

然后是 numpy：

pip3 install numpy

安装依赖：

sudo apt-get install build-essential
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev

下载 OpenCV 3.0，编译安装：

wget https://github.com/Itseez/opencv/archive/3.0.0.zip

unzip 3.0.0.zip && cd 3.0.0
mkdir build && cd build

cmake -D CMAKE_BUILD_TYPE=Release \
-D CMAKE_INSTALL_PREFIX=/usr/local  \
PYTHON3_EXECUTABLE=/usr/bin/python3 \
PYTHON_INCLUDE_DIR=/usr/include/python3.4 \
PYTHON_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.4m.so \
PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.4/dist-packages/numpy/core/include ..

make -j4
sudo make install

测试一下：

# python3
import cv2

OSX 10.10.3

开发环境比较乱，一般使用独立的虚拟环境，以往一般用virtualenv，Python3 已经内置了该功能模块：

// python3 -m venv <virtualenv-dir>
python3 -m venv venv3
source venv3/bin/activate
pip install numpy

然后是编译安装 OpenCV，和 Ubuntu 基本一致，只是一些参数路径稍有差别：

cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D PYTHON3_EXECUTABLE=/path/to/venv3/bin/python \
-D PYTHON3_PACKAGES_PATH=/path/to/venv3/lib/python3.4/site-packages \
-D PYTHON3_LIBRARY=/Library/Frameworks/Python.framework/Versions/3.4/lib/libpython3.4m.dylib \
-D PYTHON3_INCLUDE_DIR=/Library/Frameworks/Python.framework/Versions/3.4/include/python3.4m \
-D PYTHON3_NUMPY_INCLUDE_DIRS=/Users/rainy/Projects/Vision/venv3/lib/python3.4/site-packages/numpy/core/include \
-D INSTALL_C_EXAMPLES=ON \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D BUILD_EXAMPLES=ON \
-D BUILD_opencv_python3=ON \
-D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib/modules ..

cmake 结果中Python 3部分如下：
Python 3:

make -j8
make install

测试一下：

import cv2
cv2.__version__
#=> '3.0.0'

参考

  1. Installation in Linux
  2. Install OpenCV 3.0 and Python 3.4+ on OSX
