安装依赖

Ubuntu20.04需要安装以下依赖

sudo apt install -y --no-install-recommends \ 
    build-essential \
    git \
    wget \
    unzip \
    yasm \
    pkg-config \
    libswscale-dev \
    libtbb2 \
    libtbb-dev \
    libjpeg-dev \
    libpng-dev \
    libtiff-dev \
    libopenjp2-7-dev \
    libavformat-dev \
    libpq-dev \
    libgtk2.0-dev libgtk-3-dev \
    libgphoto2-dev \
    libtiff5-dev libjpeg8-dev libpng-dev cmake make \
    libavformat-dev libavcodec-dev libswscale-dev libdc1394-22-dev libavresample-dev \
    libxine2-dev libv4l-dev \
    libatlas-base-dev \
    libfaac-dev libmp3lame-dev libtheora-dev \
    libvorbis-dev libxvidcore-dev \
    libeigen3-dev \
    libgstreamer1.0-0 gstreamer1.0-plugins-base \
    gstreamer1.0-plugins-good \
    gstreamer1.0-plugins-bad \ 
    gstreamer1.0-plugins-ugly \ 
    gstreamer1.0-libav \
    gstreamer1.0-tools \
    python3.8-dev python3-pip \

pip3 install numpy

下载opencv3.1.0和contrib

假设下载目录为OP_DIR=$HOME/opencv_project

cd $OP_DIR
git clone https://github.com/opencv/opencv.git
cd opencv && git checkout 3.1.0 && cd ..
git clone https://github.com/opencv/opencv_contrib.git
cd opencv_contrib && git checkout 3.1.0 && cd ..

修复链接

如果直接cmake检查，在Ubuntu20.04会出现依赖错误

1. linux/videodev.h not found

sudo ln -sf /usr/include/libv4l1-videodev.h /usr/include/linux/videodev.h

2. ffmpeg/avformat.h not found

sudo mkdir -p /usr/include/ffmpeg 
sudo ln -sf /usr/include/x86_64-linux-gnu/libavcodec/*.h /usr/include/ffmpeg 
sudo ln -sf /usr/include/x86_64-linux-gnu/libavformat/*.h /usr/include/ffmpeg 
sudo ln -sf /usr/include/x86_64-linux-gnu/libswscale/*.h /usr/include/ffmpeg

3. sys/videoio.h not found

sudo mkdir -p /usr/include/sys && sudo touch /usr/include/sys/videoio.h

Cmake检查并编译安装

cd $OP_DIR
mkdir build && cd build

-D BUILD_opencv_java=OFF \
-D WITH_CUDA=OFF \
-D WITH_OPENGL=ON \

-D ENABLE_PRECOMPILED_HEADERS=OFF \ # stdlib.io not found
