opencv安装问题总结

#opencv安装流程

代码中部分软件或者是库的版本号根据自己使用的实际版本更改

最后make -j4 建议使用的树莓派运存大点的加4

sudo apt-get update

sudo apt-get install -y build-essential git cmake pkg-config \
    libjpeg-dev libtiff5-dev libjasper-dev libpng12-dev \
    libavcodec-dev libavformat-dev libswscale-dev libv4l-dev \
    libxvidcore-dev libx264-dev libgtk2.0-dev \
    libatlas-base-dev gfortran \
    python2.7-dev python3-dev

and then
cd ~
wget -O opencv.zip https://github.com/Itseez/opencv/archive/3.4.3.zip
unzip opencv.zip
wget -O opencv_contrib.zip 
https://github.com/Itseez/opencv_contrib/archive/3.4.3.zip
unzip opencv_contrib.zip
cd opencv-3.4.3/
mkdir build
cd 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_EXTRA_MODULES_PATH=~/opencv_contrib-3.4.3/modules \
      -D BUILD_EXAMPLES=ON ..

make -j4
make clean
make
sudo make install

 

#release配置

注意根据opencv库的版本更改，如果相对路径找不到就使用绝对路径，最后两个点不要漏了

通用配置

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE  \
-D CMAKE_INSTALL_PREFIX=/usr/local  \
-D OPENCV_EXTRA_MODULES_PATH=/home/pi/opencv_contrib-4.2.0/modules \
-D INSTALL_PYTHON_EXAMPLES=ON  \
-D BUILD_EXAMPLES=ON ..
 

 

详细配置

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE \

            -D CMAKE_INSTALL_PREFIX=$cwd/installation/OpenCV-"$cvVersion" \
            -D INSTALL_C_EXAMPLES=ON \
           -D INSTALL_PYTHON_EXAMPLES=ON \
            -D WITH_TBB=ON \
            -D WITH_V4L=ON \
            -D OPENCV_PYTHON3_INSTALL_PATH=$cwd/OpenCV-$cvVersion-py3/lib/python3.5/site-packages \
        -D WITH_QT=ON \
        -D WITH_OPENGL=ON \
        -D OPENCV_EXTRA_MODULES_PATH=~/opencv_contrib-3.4.3/modules \
        ****-D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules \
        -D INSTALL_PYTHON_EXAMPLES=ON \
        -D BUILD_EXAMPLES=ON ..

类似于以上很多都是路径问题可以使用find等查找命令将实际绝对路径添加到相应文件中错误的induced部分可能会存在部分文件缺失比如boostdesc_bgm.i只需在网上百度下载放到指定目录即可

参考文章https://blog.youkuaiyun.com/weixin_44152895/article/details/102882502里面有boostdesc_bgm.i下载链接
根据链接提示   仔细阅读出现的error 查找确切问题文档 找到缺失文档路径 添加到问题文档中（绝对路径）

编译过程可能会烧坏树莓派，请给它安排风扇，打工派不容易。
