1、首先是配置好opencv的依赖库
yum install cmake gcc gcc-c++ gtk+-devel gimp-devel gimp-devel-tools gimp-help-browser zlib-devel libtiff-devel libjpeg-devel libpng-devel gstreamer-devel libavc1394-devel libraw1394-devel libdc1394-devel jasper-devel jasper-utils swig python libtool nasm build-essential ant
2、下载opencv
华为云obs：https://obs-gyktest.obs.cn-southwest-2.myhuaweicloud.com/ajar/opencv-3.4.13.zip
可以去官网自行下载！！！注意版本！（https://opencv.org/releases/）
3、解压后cd到opencv-3.4.13
cd opencv-3.4.13
mkdir build
cd build
cmake -d cmake_build_type=release -d cmake_install_prefix=/usr/local -dbuild_tests=off ..
make -j8
备注：如果没有cmake，请使用https://blog.csdn.net/sz76211822/article/details/74729272 方式安装cmake
把bin目录中的jar包配置到项目中去
