opencv安装

提示：最好先安装Qt , 再回来安装opencv!

1. 安装依赖包

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 libtiff-dev libjasper-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

出现下面错误

errorE: unable to locate libjasper-dev

就运行下面命令

sudo apt-get install software-properties-common
sudo add-apt-repository "deb http://mirrors.tuna.tsinghua.edu.cn/ubuntu-ports/ xenial main multiverse restricted universe"
sudo apt update
sudo apt install libjasper1 libjasper-dev

然后继续安装依赖包

2. 下载并解压opencv安装包

从官网下载opencv的Sources, 并解压: https://opencv.org/releases/

3. 安装OpenCV

打开终端, cd到opencv解压位置

sudo mv opencv-4.1.1 /usr/local

cd /usr/local/opencv-4.1.1

sudo mkdir build

cd build

sudo cmake -D CMAKE_BUILD_TYPE=RELEASE \
-D CMAKE_INSTALL_PREFIX=/usr/local \
-D CMAKE_PREFIX_PATH=/opt/Qt5.13.0/5.13.0/gcc_64/lib/cmake/Qt5 \
-D WITH_TBB=ON \
-D WITH_V4L=ON \
-D WITH_QT=ON \
-D WITH_GTK=ON \
-D WITH_OPENGL=ON \
-D WITH_VTK=ON \
-D OPENCV_GENERATE_PKGCONFIG=YES ..

sudo make -j4

sudo make install
