Opencv在linux下安装和配置

Linux系统信息查看命令:

uname -a

Linux node17-charlie 3.10.0-1160.66.1.el7.x86_64 #1 SMP Wed May 18 16:02:34 UTC 2022 x86_64 x86_64 x86_64 GNU/Linux

1. 安装相关依赖

sudo yum install -y cmake gcc gtk2-devel numpy unzip 
sudo yum install -y qt5-qtbase-devel python-devel jasper-devel 
sudo yum install -y openexr-devel libwebp-devel libjpeg-turbo-devel
sudo yum install -y freeglut-devel mesa-libGL mesa-libGL-devel libtiff-devel

sudo yum install -y libdc1394-devel tbb-devel eigen3-devel
sudo yum install -y boost boost-thread boost-devel libv4l-devel
sudo yum install -y gstreamer-plugins-base-devel
sudo yum install -y gcc-c++
sudo yum install -y ant

2. 下载源码上传到服务器

版本:OpenCV-4.0.0

提取码:5fiu

cd /root/charlie
tar -xzvf opencv-4.0.0.tar.gz

cd opencv-4.0.0
mkdir build
cd build

cmake -D CMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..

遇到错误:CMake 3.5.1 or higher is required. You are running version 2.8.12.2
解决办法:

cmake --version
yum remove cmake
curl -O https://cmake.org/files/v3.6/cmake-3.6.0-Linux-x86_64.tar.gz
tar -zxvf cmake-3.6.0-Linux-x86_64.tar.gz
mv cmake-3.6.0-Linux-x86_64 /usr/local
mv cmake-3.6.0-Linux-x86_64.tar.gz /usr/local
vim /etc/profile

在文件末尾处增加以下代码
export PATH=$PATH:/usr/local/cmake-3.6.0-Linux-x86_64/bin

source /etc/profile
cmake --version

继续执行:

cmake -D CMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/usr/local ..

3. 开始编译

sudo make
sudo make install

#做完这一步正常来说会生成相关jar包,进入opencv存放目录/buld/bin下,可以找到opencv-400.jar,
#通过该jar包可在项目中调用opencv,如果没有找到再执行以下操作,完成后再去上述目录中找jar包

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -DBUILD_TESTS=OFF ..
make -j8
sudo make install

4. 复制so文件到/usr/local/lib下,使得在java环境下顺利调用opencv

将opencv存放目录/build/lib下的所有后缀为so的文件复制到/usr/local/lib
