基于java基础镜像，dockerfile源码编译安装opencv

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

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 -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/java/opencv-4.6.0/build ..

或者

cmake -D CMAKE_BUILD_TYPE=RELEASE -D BUILD_opencv_world=ON  -D OPENCV_DNN_CUDA=OFF -D WITH_CUDA=OFF -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_world460.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 -j12
 
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 CMAKE_INSTALL_PREFIX=/usr/local/java/opencv-4.6.0/javaLib -DBUILD_TESTS=OFF ..

或者

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local/opencv460 -DBUILD_TESTS=OFF -DBUILD_opencv_java=ON ..

make -j12
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:

报错

Failed to fetch http://mirrors.tencentyun.com/debian/pool/main/v/vim/xxd_8.1.0875-5_amd64.deb  Something wicked happened resolving 'mirrors.tencentyun.com:http' (-5 - No address associated with hostname)

解决方案

ping后发现网络不通

ping mirrors.tencentyun.com

cat /etc/apt/sources.list

把内网地址mirrors.tencentyun.com换成外网mirrors.tencent.com

通过拷贝文件的方式更改

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/
