1 安装依赖库
sudo apt-get install build-essential git cmake pkg-config -y

sudo apt-get install libjpeg8-dev libtiff5-dev libjasper-dev libpng-dev libavcodec-dev libavformat-dev libswscale-dev libv4l-dev libgtk2.0-dev libatlas-base-dev -y

2 下载opencv4.2 和contrib 扩展模块。

或者

生成makefile
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D INSTALL_C_EXAMPLES=ON -D OPENCV_EXTRA_MODULES_PATH=/home/sunrise/Downloads/opencv_contrib-4.2.0/modules -D BUILD_EXAMPLES=ON -D OPENCV_ENABLE_NONFREE=YES -D WITH_LIBV4L=ON ..


OPENCV_ENABLE_NONFREE 是使用专利相关的算法

4 make -j4 编译
编译过程中内存出现溢出
增加swap 交换内存2G，重启后需要重新设置。

解决方法：将/home/pi/Downloads/opencv-4.2.0/modules/features2d/test文件下的
test_descriptors_invariance.impl.hpp
test_descriptors_regression.impl.hpp
test_detectors_invariance.impl.hpp
test_detectors_regression.impl.hpp
test_invariance_utils.hpp
这5个文件复制粘贴到opencv_contrib-4.2.0/modules/xfeatures2d/test这个目录下，不要多拷贝。
