ubuntu18.04在docker容器中编译opencv3.2.0

1. 创建目录并clone代码

   mkdir opencv
   cd opencv
   
   git clone https://github.com/opencv/opencv.git
   cd opencv
   git checkout 3.2.0
   mkdir build
   cd ..
   
   git clone https://github.com/opencv/opencv_contrib.git
   cd opencv_contrib
   git checkout 3.2.0
   cd ..
   

2. 遇到 ippicv_linux_20151201.tgz 下载不成功

   • github直接搜索 ippicv
   • git clone https://github.com/lonesoul/ippicv.git
   • 将其中的ippicv_linux_20151201.tgz文件拷贝到 opencv/opencv/3rdparty/ippicv/downloads/linux-808b791a6eac9ed78d32a7666804320e下面进行替换

3. 遇到boostdesc_bgm.i 等找不到

   • git clone https://github.com/opencv/opencv_3rdparty.git
   • git checkout contrib_xfeatures2d_boostdesc_20161012
   • 将缺失的文件,拷贝到opencv/opencv_contrib/modules/xfeatures2d/src
4. 类似的问题可以参考上面两种解决思路

5. 编译

   cd opencv/opencv/build
   
   cmake -D CMAKE_BUILD_TYPE=RELEASE \
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    -D INSTALL_C_EXAMPLES=ON \
    -D INSTALL_PYTHON_EXAMPLES=ON \
    -D OPENCV_GENERATE_PKGCONFIG=ON \
    -D OPENCV_EXTRA_MODULES_PATH=/home/mywork/opencv/opencv_contrib/modules \
    -D BUILD_EXAMPLES=ON ..
   

编译下载失败的解决办法

cmake -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.x/modules ../opencv-4.x -DCMAKE_INSTALL_PREFIX=../install -DOPENCV_DOWNLOAD_MIRROR_ID=gitcode -DOPENCV_GENERATE_PKGCONFIG=ON
