OpenCV自学笔记32. ubuntu 安装python3+opencv3的过程记录

sudo apt-get install python3-numpy

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

wget https://codeload.github.com/opencv/opencv/zip/3.2.0[/code] 
然后解压缩，进入解压后的目录，并创建build目录。

unzip 3.2.0

cd opencv-3.2.0

mdkir build

cd build


接下来执行make

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 -j2 # 利用2个核执行




最后别忘了：
sudo make install




4、测试

在shell中输入python3，尝试import cv2，如果不报错，说明安装成功。
