OpenCV4 源码编译安装 | 记录

参考资料

环境

  • wsl2-ubuntu20.04
  • opencv4.5.5

步骤

  1. 安装GCC \ CMake \ make

    sudo apt install -y g++
    
sudo apt install -y cmake
    
sudo apt install -y make

  2. 下载源码

    github地址：https://github.com/opencv

    opencv官网：https://opencv.org/releases/

    注：opencv_contrib应与opencv版本号相同

  3. 编译安装

    注：可将opencv_contrib包放置在opencv文件夹内。

    创建build文件夹：

    cd opencv<>
    
mkdir build && cd build

    配置cmake：

    cmake -D CMAKE_BUILD_TYPE=RELEASE \
    
    -D CMAKE_C_COMPILER=/usr/bin/gcc \
    
    -D CMAKE_INSTALL_PREFIX=/usr/local \
    
    -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.5.5/modules/ \
    
    -D CUDA_CUDA_LIBRARY=/usr/local/cuda/lib64/stubs/libcuda.so \
    
    -D CUDA_ARCH_BIN=7.0 \
    
    -D CUDA_ARCH_PTX="" \
    
    -D WITH_CUDA=ON \
    
    -D WITH_TBB=ON \
    
    -D WITH_FFMPEG=ON \
    
    -D BUILD_PYTHON_SUPPORT=ON \
    
    -D BUILD_NEW_PYTHON_SUPPORT=ON \
    
    -D BUILD_OPENCV_PYTHON3=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_GSTREAMER=ON \
    
    -D WITH_OPENGL=ON \
    
    -D ENABLE_FAST_MATH=1 \
    
    -D CUDA_FAST_MATH=1 \
    
    -D OPENCV_GENERATE_PKGCONFIG=ON \
    
    -D OPENCV_PC_FILE_NAME=opencv.pc \
    
    -D CUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-11.0 \
    
    -D CMAKE_LIBRARY_PATH=/usr/local/cuda/lib64/stubs \
    
    -D WITH_CUBLAS=ON \
    
    -D WITH_NVCUVID=ON \
    
    -D BUILD_opencv_cudacodec=ON \
    
    -D OPENCV_DNN_CUDA=ON \
    
    -D WITH_CUDNN=ON \
    
    -D OPENCV_ENABLE_NONFREE=ON\
    
    -D WITH_GSTREAMER=ON \
    
    -D PYTHON3_INCLUDE_DIR=/usr/include/python3.8 \
    
    -D PYTHON3_PACKAGES_PATH=/usr/lib/python3/dist-packages \
    
    -D BUILD_EXAMPLES=ON ..

    以上为配置参数示例，其中OPENCV_EXTRA_MODULES_PATH为opencv_contrib文件夹路径。

    注：对于opencv4.5.5版本对于python的支持，建议增加-D PYTHON3_INCLUDE_DIR=/usr/include/python3.8，否则可能出现无法import cv2状况，具体原因未深究。

    配置完成结果实例如下：

    编译：

    make

    安装：

    sudo make install

    默认安装位置：

    • /usr/local/bin - executable files
    • /usr/local/lib - libraries (.so)
    • /usr/local/cmake/opencv4 - cmake package
    • /usr/local/include/opencv4 - headers
    • /usr/local/share/opencv4 - other files (e.g. trained cascades in XML format)

  4. 验证

    该命令显示opencv版本号。

    c++:

    pkg-config opencv --modversion

    python:

    python3
    
import cv2
    
print(cv2.__version__)
