本文详细介绍了如何在x86_64、ARM及ARM64架构上使用CMake配置并编译OpenCV源码，包括Python环境的设置与依赖库的指定，适用于跨平台开发人员。

部署运行你感兴趣的模型镜像

1. opencv源码包创建build目录:

mkdir build

2.在build目录执行cmake，不同架构命令为:

1. install numpy
apt-get install python-numpy
apt-get install python3-numpy

x86_64版：
cmake\
-D CMAKE_BUILD_TYPE=RELEASE\
-D INSTALL_C_EXAMPLES=OFF\
-D INSTALL_PYTHON_EXAMPLES=ON\
-D BUILD_EXAMPLES=OFF\
-D ENABLE_CXX11=ON\
-D BUILD_opencv_python3=ON\
-D BUILD_opencv_python2=ON\
-D BUILD_opencv_java=OFF\
-D PYTHON3_EXECUTABLE=$(which python3)\
-D PYTHON3_INCLUDE_DIR=/usr/include/python3.5m\
-D PYTHON3_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython3.5m.so.1\
-D PYTHON3_NUMPY_PATH=/usr/local/lib/python3.5/dist-packages\
-D PYTHON2_EXECUTABLE=$(which python2)\
-D PYTHON2_INCLUDE_DIR=/usr/include/python2.7\
-D PYTHON2_LIBRARY=/usr/lib/x86_64-linux-gnu/libpython2.7.so.1\
-D PYTHON2_NUMPY_PATH=/usr/local/lib/python2.7/dist-packages ..

ARM版：
cmake\
-D CMAKE_BUILD_TYPE=RELEASE\
-D INSTALL_C_EXAMPLES=OFF\
-D ENABLE_NEON=ON\
-D ENABLE_VFPV3=ON\
-D ENABLE_CXX11=ON\
-D INSTALL_PYTHON_EXAMPLES=ON\
-D BUILD_EXAMPLES=OFF\
-D BUILD_opencv_python3=ON\
-D BUILD_opencv_python2=ON\
-D BUILD_opencv_java=OFF\
-D PYTHON3_EXECUTABLE=$(which python3)\
-D PYTHON3_INCLUDE_DIR=/usr/include/python3.5m\
-D PYTHON3_LIBRARY=/usr/lib/arm-linux-gnueabihf/libpython3.5m.so.1\
-D PYTHON3_NUMPY_PATH=/usr/lib/python3/dist-packages\
-D PYTHON2_EXECUTABLE=$(which python2)\
-D PYTHON2_INCLUDE_DIR=/usr/include/python2.7\
-D PYTHON2_LIBRARY=/usr/lib/arm-linux-gnueabihf/libpython2.7.so.1\
-D WITH_LIBV4L=ON\
-D PYTHON2_NUMPY_PATH=/usr/lib/python2.7/dist-packages ..

ARM64版：
