linux-Ubantu系统，基于java基础镜像，dockerfile源码编译安装opencv，重新制作docker镜像
官方文档最准确的安装参考：https://docs.opencv.org/4.6.0/d7/d9f/tutorial_linux_install.html
安装参考：https://blog.csdn.net/Taylor_0522/article/details/119172807
使用参考：https://blog.wangqi.love/articles/Java/Java%E8%B0%83%E7%94%A8opencv.html
dockerfile
FROM coding-public-docker.pkg.coding.net/public/docker/openjdk:8
制作镜像并进入容器
docker build -t face-petition-java:1.0.0.0802 .
docker run -it --entrypoint=/bin/bash face-petition-java:1.0.0.0802
通过拷贝文件的方式更改镜像源
把内网地址mirrors.tencentyun.com换成外网mirrors.tencent.com
docker cp 3abdb23ac326:/etc/apt/sources.list /data/mart/face_insight/java_dockerfile/
docker cp /data/mart/face_insight/java_dockerfile/sources.list 3abdb23ac326:/etc/apt/
安装依赖
apt update
apt install build-essential cmake net-tools git vim unzip iputils-ping -y
apt install libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev libswresample-dev libavresample-dev libgphoto2-dev
apt install libgtk3.0 #安装过程中选 6 Asia 70 Shanghai
apt install libgstreamer1.0-dev libgstreamer1.0-dev
apt install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libdc1394-22-dev
apt install ant
下载opencv
wget https://github.com/opencv/opencv/archive/4.6.0.zip
unzip 4.6.0.zip
cd opencv-4.6.0
mkdir build && cd build
cmake介绍
cmake参数指令介绍
CMAKE_BUILD_TYPE:build类型(Debug,Release,…),CMAKE_BUILD_TYPE=Debug;
CMAKE_INSTALL_PREFIX:工程安装目录，所有生成和调用所需的可执行程序，库文件，头文件都会安装到该路径下，Unix/Linux下默认为/usr/local, windows下默认为C:\Program Files;
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv460 ..
注意：其中，BUILD_opencv_world=ON 将所有opencv必要库绑定到libopencv_world.so文件，工程中直接使用该 .so文件即可；CMAKE_INSTALL_PREFIX=/usr/local/opencv460 将opencv相关安装到/usr/local/opencv460目录中，工程中注意连接该目
编译安装
make -j8
make install
运行结束后，即可以用C++调用了。
用cmake生成java的jar
cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_opencv_world=ON -D CMAKE_INSTALL_PREFIX=/usr/local/opencv460 -DBUILD_TESTS=OFF -DBUILD_opencv_java=ON ..
make -j8
make install
以上操作结束后, 看看build文件夹, bin目录下是不是有一个opencv-460.jar文件:
以上操作结束后,/usr/local/opencv460/share/java/opencv4目录也有相关的库文件和jar文件:
/usr/local/opencv460/share/java/opencv4
libopencv_java460.so opencv-460.jar
制作镜像并提交
docker commit 3abdb23ac326 face-petition-java-new:1.0.0.0802
docker tag face-petition-java-new:1.0.0.0802 xx/face-petition-java-new:1.0.0.0802
docker login -u xx -p xx xx-docker.pkg.coding.net
docker push xx/face-petition-java-new:1.0.0.0802
