- 下载
opencv源码
brew install wget
sudo wget -O opencv.zip https://github.com/opencv/opencv/archive/4.8.0.zip
sudo wget -O opencv_contrib.zip https://github.com/opencv/opencv_contrib/archive/4.8.0.zip
sudo unzip opencv.zip
sudo unzip opencv_contrib.zip
- 编译安装
进入下载路径，并创建build文件夹
cd opencv-4.8.0
mkdir build && cd build
在 build 文件夹 下新建 run.sh，并输入如下代码，其中BUILD_opencv_java设置为ON，OPENCV_EXTRA_MODULES_PATH 设置为下载的 opencv_contrib 的modules 路径
set -ex
cmake \
-DCMAKE_SYSTEM_PROCESSOR=arm64 \
-DCMAKE_OSX_ARCHITECTURES=arm64 \
-DWITH_OPENJPEG=OFF \
-DWITH_IPP=OFF \
-DCMAKE_BUILD_TYPE=RELEASE \
-DCMAKE_INSTALL_PREFIX=/usr/local/opencv \
-DJAVA_INCLUDE_PATH=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include \
-DJAVA_AWT_INCLUDE_PATH=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include \
-DJAVA_INCLUDE_PATH2=/Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include/darwin \
-DBUILD_opencv_python2=OFF \
-DBUILD_opencv_java=ON \
-DINSTALL_PYTHON_EXAMPLES=OFF \
-DINSTALL_C_EXAMPLES=OFF \
-DBUILD_ZLIB=OFF \
-DOPENCV_ENABLE_NONFREE=ON \
-DOPENCV_EXTRA_MODULES_PATH=/Users/huipeng/Desktop/AIGC/opencv/opencv_contrib-4.8.0/modules \
-DBUILD_EXAMPLES=ON ..
输入 bash run.sh 运行该命令，成功后输出:
-- OpenCL: YES (no extra features)
-- Include path: NO
-- Link libraries: -framework OpenCL
--
-- Python (for build): /opt/homebrew/bin/python3
--
-- Java:
-- ant: NO
-- Java: YES (ver 1.8.0.381)
-- JNI: /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include/darwin /Library/Java/JavaVirtualMachines/jdk-1.8.jdk/Contents/Home/include
-- Java wrappers: YES (JAVA)
-- Java tests: NO
--
-- Install to: /usr/local/opencv

-- Build files have been written to: /Users/huipeng/Desktop/AIGC/opencv/opencv-4.8.0/build
然后输入如下指令编译:
sudo make -j8
最后输入如下指令安装:
sudo make install
完成之后会在两个地方出现jar文件和lib文件，一个是build路径
opencv-4.8.0/build/bin/opencv-480.jar
opencv-4.8.0/build/lib/libopencv_java480.dylib
一个是安装路径:
/usr/local/opencv/share/java/opencv4/libopencv_java480.dylib
/usr/local/opencv/share/java/opencv4/opencv-480.jar
- 设置 Java Library Path:
-Djava.library.path=/usr/local/opencv/share/java/opencv4
- 设置 Libraries
