Linux环境下编译并使用java_opencv

1.安装编译环境 gcc yum -y install gcc gcc-c++ openssl openssl-devel tar 2.准备安装cmake 以下安装需要的模块 yum install -y libxml2 libxml2-devel bzip2 bzip2-devel libcurl libcurl-devel libjpeg libjpeg-devel zstd libzstd-devel curl libcurl-devel libpng libpng-devel 3.下载CMake3.23.0 源代码（嫌慢） wget https://github.com/Kitware/CMake/releases/download/v3.23.0/cmake-3.23.0.tar.gz 4.编译CMake tar -zxvf cmake-3.23.0.tar.gz cd cmake-3.23.0 ./configure --prefix=/usr/local/cmake-3.23.0 gmake -j4 gmake install 5.配置环境 touch /etc/profile.d/cmake.sh chmod 777 /etc/profile.d/cmake.sh echo -e '\nexport PATH=/usr/local/cmake-3.23.0/bin:$PATH\n' >> /etc/profile.d/cmake.sh source /etc/profile.d/cmake.sh ln -sv /usr/local/gcc-11.2.0/include/c++/11.2.0 /usr/include/c++/11.2.0 6.安装ant（最后生成的jar是由ant编译） yum -y install ant 7.下载opencv-4.5.5 以及 opencv_contrib-4.5.5 （如果下不了去官网下） wget -O opencv-4.5.5.tar.gz https://github.com/opencv/opencv/archive/refs/tags/4.5.5.tar.gz wget -O opencv_contrib-4.5.5.tar.gz https://github.com/opencv/opencv_contrib/archive/refs/tags/4.5.5.tar.gz 官网地址： https://opencv.org/releases/# 8.解压并构建 tar -zxvf opencv-4.5.5.tar.gz tar -zxvf opencv_contrib-4.5.5.tar.gz cd ./opencv-4.5.5 mkdir build && cd build cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_GENERATE_PKGCONFIG=ON -D OPENCV_EXTRA_MODULES_PATH=/opencv/opencv_contrib-4.5.5/modules -D ENABLE_CXX11=ON -D WITH_1394=OFF -D BUILD_opencv_xfeatures2d=OFF -D BUILD_SHARED_LIBS=OFF -D BUILD_TESTS=OFF .. 需要注意的是 OPENCV_EXTRA_MODULES_PATH = 你安装opencv_contrib的目录，这里需要修改 9.编译opencv make -j4 #按你的服务器的核心数来 make install 10.安装 在/usr/local/share/java/opencv4 会有所需jar包和so库 如果后续运行遇到找到jar包的情况 把jar包和so库转移到/usr/lib/目录之下 11.补充1 同时兼容windows与linux,需要引入依赖 org.openpnp opencv 4.5.5-1 12.补充2 初始化依赖 加载opencv库 if ("Linux".equalsIgnoreCase(osName)) { System.loadLibrary(Core.NATIVE_LIBRARY_NAME); }
