安裝OpenCV

---

OpenCV 官網，下載見 SourceForge and GitHub。

若使用官網版本安裝不成功，則可試試Github版本。
或者

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

安裝依賴庫

OpenCV下載

wget https://codeload.github.com/opencv/opencv/zip/3.2.0 unzip 3.2.0 && cd opencv-3.2.0 mkdir build cd build

或者 推薦下面的下載方法。

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

編譯安裝

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON .. make -j4 sudo make install

或者

~/build$ cmake ~/opencv -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ../opencv

測試

python import cv2

配置Python3.5 調用OpenCV

---

以上OpenCV的python解釋器版本是2.7, Python3.5想調用OpenCV，如何配置呢

安裝依賴庫

sudo apt-get update sudo apt-get install build-essential cmake pkg-config sudo apt-get install libjpeg8-dev libtiff5-dev libjasper-dev libpng12-dev sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev sudo apt-get install libxvidcore-dev libx264-dev sudo apt-get install libgtk-3-dev sudo apt-get install libatlas-base-dev gfortran sudo apt-get install python3-setuptools python3-dev sudo easy_install3 pip pip3 install numpy sudo apt-get install cmake git libgtk2.0-dev

---

特別注意

sudo apt install python3-dev libpython3.5-dev python3-numpy

---

1. 進入opencv-3.2.0/build/路徑下，執行ccmake

sudo ccmake .

2. 添加python3路徑
向下翻頁，找到python3，手動添加自己的python3路徑

具體添加細節如下

CMAKE_BUILD_TYPE=Release CMAKE_INSTALL_PREFIX=/usr/local PYTHON3_EXECUTABLE=/usr/bin/python3 PYTHON3_INCLUDE_DIR=/usr/include/python3.5 PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.5/dist-packages/numpy/core/include

命令行配置方法

cmake -D CMAKE_BUILD_TYPE=RELEASE \-D CMAKE_INSTALL_PREFIX=/usr/local \ -D PYTHON3_EXECUTABLE=/usr/bin/python3 \ -D PYTHON3_INCLUDE_DIR=/usr/include/python3.5 \ -D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so \ -D PYTHON3_NUMPY_INCLUDE_DIRS=/usr/local/lib/python3.5/dist-packages/numpy/core/include ..

3. 生成make文件

按c鍵配置。如果有錯，例如找不到xx庫，自行調整對應選項或者安裝對應庫。配置成功后，按g鍵生成makefile。

4. make一下

make一下。多核處理器優勢很大，幾分鐘就make好了。

sudo make -j12 # 根據你自己電腦核心數 sudo make install

5. 驗證

python3 import cv2

6.查詢OpenCV版本

pkg-config --modversion opencv

或者

python import cv2 cv2.__version__
