安装OpenCV的依赖包
sudo apt-get install build-essential
sudo apt-get install 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 libtiff5-dev libdc1394-22-dev # 处理图像所需的包
sudo apt-get install libavcodec-dev libavformat-dev libswscale-dev libv4l-dev liblapacke-dev
sudo apt-get install libxvidcore-dev libx264-dev # 处理视频所需的包
sudo apt-get install libatlas-base-dev gfortran # 优化opencv功能
sudo apt-get install ffmpeg
下载OpenCV 4.2.0和OpenCV Contrib 4.2.0
OpenCV 4.2.0:github.com/opencv/open…
OpenCV Contib 4.2.0:github.com/opencv/open…
将两个压缩包保存到 /home/username/opencv4.2/，进行解压； 最后目录结构:
/home/username/opencv4.2/
opencv-4.2.0/
opencv_contrib-4.2.0/
使用cmake构建库
cd /home/username/opencv4.2/opencv-4.2.0
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local ..
make
make install (需要管理员权限)
sudo /bin/bash -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig
