opencv3.2 安裝說(shuō)明書
軟件環(huán)境
ubuntu 14,04 python2.7 cmake , g++, gcc
1 安裝OpenCV依賴
1.1 升級(jí)系統(tǒng)
$ sudo apt-get update
$ sudo apt-get upgrade
1.2 安裝編譯工具
由于是通過(guò)源代碼安裝 , 說(shuō)以需要安裝編譯工具.
$ sudo apt-get install build-essential cmake pkg-config
1.3 安裝依賴庫(kù)
由于OpenCV是計(jì)算機(jī)視覺庫(kù)，總需要加載一些圖像文件（ JPEG, PNG, TIFF）。使用下面命令安裝一些必要的圖像庫(kù)：
$ sudo apt-get install libjpeg8-dev libtiff5-dev libjasper-dev libpng12-dev
除了圖片之外，OpenCV還要處理視頻文件。使用下面命令安裝一些視頻編解碼庫(kù)
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev
sudo apt-get install libxvidcore-dev libx264-dev
OpenCV的GUI模塊highgui依賴Gtk。安裝gtk庫(kù)：
sudo apt-get install libgtk-3-dev
下面安裝一些可以提高OpenCV性能的庫(kù)，如矩陣操作:
sudo apt-get install libatlas-base-dev gfortran
安裝Python2和Python3的開發(fā)庫(kù)：
sudo apt-get install python2.7-dev python3.5-dev
PS Ubuntu14.04中含有python2.7 , 如果不想自己的系統(tǒng)環(huán)境太復(fù)雜,可以選擇不去安裝python2.7
下載opencv 源代碼
目前OpenCV的最新穩(wěn)定版是3.2 , 可以去opencv官網(wǎng)上下載, 也可以去github總下載最新版本
最好再下載opencv_contrib,
opencvcontrib模塊是Opencv 沒(méi)有經(jīng)過(guò)足夠測(cè)試的的新功能模塊.OpenCV 在發(fā)布新的版本之前,首先在opencvcontrib倉(cāng)庫(kù)中發(fā)布。當(dāng)模塊成熟并獲得普及后，便轉(zhuǎn)移到中央OpenCV存儲(chǔ)庫(kù)，并發(fā)布新的版本; :)
注意：opencv和opencv_contrib的版本要一致
# 由于我下載的opencv3.2? 所以會(huì)在github下找到相應(yīng)的版本
wget https://github.com/opencv/opencv_contrib/archive/3.2.0.tar.gz
tar -zvxf 3.2.0.tar.gz? # 解壓以后生成 opencv_contrib-3.2.0
2. 編譯OpenCV
切換到opencv 的build 目錄 , opencvbuilddirectory
cd ? ## 跳轉(zhuǎn)到opencv 目錄
mkdir build? ## 創(chuàng)建 opencv_build_directory
cd ? ## 切換到 opencv_build_directory 目錄
生成編譯文件
cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D INSTALL_PYTHON_EXAMPLES=ON \
-D INSTALL_C_EXAMPLES=OFF \
-D OPENCV_EXTRA_MODULES_PATH=/home/linux/work_space/opencv_contribute/opencv_contrib-3.2.0/modules \
-D PYTHON_EXECUTABLE=/usr/bin/python2.7 -D BUILD_EXAMPLES=ON ..
make -j? ? #NUM 自己設(shè)定? 我設(shè)置的是80
ps: 我這里opencvcontrib 的目錄是/home/linux/workspace/opencvcontribute/opencvcontrib-3.2.0/ ; 所以參數(shù)寫成 -D OPENCVEXTRAMODULESPATH=/home/linux/workspace/opencvcontribute/opencvcontrib-3.2.0/modules
最后的 .. ?是由于build 目錄在openCV里面, 我想編譯build 外面的文件,所以要用相對(duì)路徑 ..?
如果是MacOS? 可以采用以下方式編譯:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local \
-D PYTHON2_PACKAGES_PATH=/usr/local/lib/python2.7/site-packages \
-D PYTHON2_LIBRARY=/Library/Frameworks/Python.framework/Versions/2.7/bin \
-D PYTHON2_INCLUDE_DIR=/Library/Frameworks/Python.framework/Headers \
-D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON \
-D BUILD_EXAMPLES=ON \
-D OPENCV_EXTRA_MODULES_PATH=/Users/lee/workspace/opencv_contrib-3.2.0/modules ..
參數(shù)說(shuō)明:
There are somevery importantoptions we are supplying to CMake here, so let’s break them down:
CMAKE_BUILD_TYPE: This option indicates that we are building a release binary of OpenCV.
CMAKE_INSTALL_PREFIX: The base directory where OpenCV will be installed.
PYTHON2_PACKAGES_PATH: Theexplicitpath to where oursite-packagesdirectory lives in ourcvvirtual environment.
PYTHON2_LIBRARY: Path to our Hombrew installation of Python.
PYTHON2_INCLUDE_DIR: The path to our Python header files for compilation.
INSTALL_C_EXAMPLES: Indicate that we want to install the C/C++ examples after compilation.
INSTALL_PYTHON_EXAMPLES: Indicate that we want to install the Python examples after complication.
BUILD_EXAMPLES: A flag that determines whether or not the included OpenCV examples will be compiled or not.
OPENCV_EXTRA_MODULES_PATH:This option is?extremely important— here we supply the path to theopencv_contribrepo that we pulled down earlier, indicating that OpenCV should compile the extra modules as well.
3 安裝
make install #? 安裝
3.1 Mac OS
PS: 如果你是MacOS 那么還需要手動(dòng)的添加cv2的相關(guān)文件到python 中;
我這里提供兩種方式:
如果使用brew 安裝的, (安裝步驟詳見?)僅需如此:
查看有沒(méi)有這個(gè)目錄?? /usr/local/Cellar/opencv/2.4.10/
cd /Library/Python/2.7/site-packages/
ln -s /usr/local/Cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv.py cv.py
ln -s /usr/local/Cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv2.so cv2.so
如果是安裝以上的源碼方式在本地編譯安裝的情況:
sudo ln -s /usr/local/Cellar/opencv/2.4.13.2/lib/python2.7/site-packages/cv2.so
/Library/Python/2.7/site-packages/cv2.so
?即可
