树莓派4b ubuntu18.04 opencv

树莓派4b上安装Ubuntu18.04和OpenCV的过程如下：

1. 首先，你需要下载Ubuntu18.04的操作系统并安装到树莓派4b上。

2. 安装OpenCV的依赖包。你可以使用以下命令来安装所需的依赖包：

sudo apt-get install build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev liblapacke-dev
sudo apt-get install libxvidcore-dev libx264-dev
sudo apt-get install libatlas-base-dev gfortran
sudo apt-get install ffmpeg

3. 下载并解压OpenCV和OpenCV_contrib。你可以在以下链接中找到下载地址：
OpenCV: https://opencv.org/opencv-4-1-1/
OpenCV_contrib: https://github.com/opencv/opencv_contrib/releases/tag/4.1.1

4. 将下载的opencv_contrib-4.1.1文件夹放在opencv-4.1.1文件夹里。

5. 使用以下命令进入opencv-4.1.1文件夹，并解压下载的文件：

cd opencv-4.1.1
unzip opencv-4.1.1.zip
unzip opencv-4.1.1.zip

6. 进入解压后的文件夹，并使用cmake进行配置和编译：

cd opencv-4.1.1
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.1.1/modules ..
make -j4
sudo make install

7. 安装完成后，你可以使用OpenCV来进行图像处理和计算机视觉相关的开发了。

请注意，上述步骤仅适用于树莓派4b上的Ubuntu18.04操作系统。如果你使用其他版本的Ubuntu或不同的操作系统，请参考相应的安装指南。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
