OpenCV源码下载OpenCV及对应版本的opencv_contrib

https://github.com/opencv 

安装cmake-gui

$ sudo apt-get install cmake-qt-gui

 

安装依赖

# Build tools:
sudo apt-get install -y build-essential cmake

# GUI (if you want to use GTK instead of Qt, replace 'qt5-default' with 'libgtkglext1-dev' and remove '-DWITH_QT=ON' option in CMake):
sudo apt-get install -y qt5-default libvtk6-dev

# Media I/O:
sudo apt-get install -y zlib1g-dev libjpeg-dev libwebp-dev libpng-dev libtiff5-dev libjasper-dev libopenexr-dev libgdal-dev

# Video I/O:
sudo apt-get install -y libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev yasm libopencore-amrnb-dev libopencore-amrwb-dev libv4l-dev libxine2-dev

# Parallelism and linear algebra libraries:
sudo apt-get install -y libtbb-dev libeigen3-dev

# Python:
sudo apt-get install -y python-dev python-tk python-numpy python3-dev python3-tk python3-numpy

打开cmake-gui,配置如下：

1 选择源文件目录为/home/yj/software/opencv3.4.2/opencv-3.4.2
2 选择构建目录为/home/yj/software/opencv3.4.2/opencv-3.4.2/build
3 选择BUILD_opencv_python2
4 选择BUILD_opencv_python3
5 选择CMAKE_INSTALL_PREFIX为/usr/local/opencv3.4.2
6 选择OPENCV_EXTRA_MODULES_PATH为/home/yj/software/opencv3.4.2/opencv_contrib-3.4.2/modules

点击Configure

在构建过程中，ippicv_2017u3_lnx_intel64_general_20180518.tgz和face_landmark_model.dat下载会比较慢，可以安装build目录中CMakeDownloadLog.txt中指定的连接下载，也可以点击下载。

下载完成后将ippicv_2017u3_lnx_intel64_general_20180518.tgz放在opencv-3.4.2/.cache/ippicv目录中，并重命名为b7cc351267db2d34b9efa1cd22ff0572-ippicv_2017u3_lnx_intel64_general_20180518.tgz，其中前半部分为md_5值

opencv-3.4.2/.cache/ippicv/b7cc351267db2d34b9efa1cd22ff0572-ippicv_2017u3_lnx_intel64_general_20180518.tgz

将face_landmark_model.dat放在opencv-3.4.2/build/share/OpenCV/testdata/cv/face目录中

/home/yj/software/opencv3.4.2/opencv-3.4.2/build/share/OpenCV/testdata/cv/face/face_landmark_model.dat

重新点击Configure即可

点击Generate

安装

$ cd opencv-3.4.2/build/
$ make
$ sudo make install

配置python环境

将/usr/local/opencv3.4.2/lib/python2.7/dist-packages目录生成cv2.so复制到/usr/local/lib/python2.7/dist-packages目录中即可
