在Ubuntu 18.04上安装OpenCV，可以按照以下步骤进行： 1. **更新包列表**: ``` sudo apt update ``` 2. **安装依赖库**: ``` sudo apt install build-essential cmake libgtk-3-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev libv4l-dev libxvidcore-dev libx264-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev libopenblas-dev libatlas-base-dev gfortran ``` 3. **下载OpenCV源码**: ``` wget -O opencv.zip https://github.com/opencv/opencv/archive/4.x.zip unzip opencv.zip cd opencv-4.x ``` 4. **配置安装**: ``` mkdir build cd build cmake .. ``` 如果有其他自定义需求，可以添加选项如 `-DWITH_CUDA=ON` 或 `-DBUILD_opencv_java=ON` 等。 5. **编译并安装**: ``` sudo make -j$(nproc) # 使用所有CPU核心加速编译 sudo make install ``` 6. **检查安装**: ``` which python3-opencv # 查看Python绑定是否安装成功 opencv_version=$(python3 -c "import cv2; print(cv2.__version__)") ``` 7. **清理临时文件**: ``` cd .. rm -rf opencv.zip build ```
