1. 安装依赖

sudo apt install build-essential \\
sudo apt install libgtk2.0-dev \\
sudo apt install libavcodec-dev \\
sudo apt install libavformat-dev \\
sudo apt install libjpeg-dev \\
sudo apt install libtiff-dev \\
sudo apt install libswscale-dev \\
sudo apt install libpng-dev \\
sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main" \\
sudo apt update \\
sudo apt install libjasper1 libjasper-dev

2. 下载opencv-4.5.0与opencv-contrib-4.5.0

wget https://github.com/opencv/opencv/archive/4.5.0.zip
wget https://github.com/opencv/opencv_contrib/archive/4.5.0.zip
unzip opencv-4.5.0.zip
unzip opencv_contrib-4.5.0.zip

3. 添加opencv_contrib依赖文件

1）移动opencv_contrib-4.5.0到opencv-4.5.0根目录下

mv opencv_contrib-4.5.0 opencv-4.5.0

2）在opencv_contrib-4.5.0/modules/xfeatures2d/src/目录下添加如下文件：

boostdesc_bgm.i
boostdesc_bgm_bi.i
boostdesc_lbgm.i
boostdesc_bgm_hd.i
boostdesc_binboost_064.i
boostdesc_binboost_128.i
boostdesc_binboost_256.i
vgg_generated_120.i
vgg_generated_80.i
vgg_generated_64.i
vgg_generated_48.i

上述文件下载地址为：

https://files.cnblogs.com/files/arxive/boostdesc_bgm.i%2Cvgg_generated_48.i%E7%AD%89.rar

3）拷贝头文件

将opencv-4.5.0/modules/features2d/test/目录下的如下文件：

test_descriptors_invariance.impl.hpp
test_descriptors_regression.impl.hpp
test_detectors_invariance.impl.hpp
test_detectors_regression.impl.hpp
test_invariance_utils.hpp

拷至opencv_contrib-4.5.0/modules/xfeatures2d/test/目录下。

4）修改头文件

（1）将opencv_contrib-4.5.0/modules/xfeatures2d/test/test_features2d.cpp文件中包含的头文件代码：

#include "features2d/test/test_detectors_regression.impl.hpp"
#include "features2d/test/test_descriptors_regression.impl.hpp"

修改为：

#include "test_detectors_regression.impl.hpp"
#include "test_descriptors_regression.impl.hpp"

（2）将opencv_contrib-4.2.0/modules/xfeatures2d/test/test_rotation_and_scale_invariance.cpp文件中包含的头文件代码：

#include "features2d/test/test_detectors_invariance.impl.hpp" 
#include "features2d/test/test_descriptors_invariance.impl.hpp"

修改为：

#include "test_detectors_invariance.impl.hpp"
#include "test_descriptors_invariance.impl.hpp

4. 编译opencv

在opencv-4.5.0根目录下创建build.sh的脚本，脚本内容如下：

#!/bin/bash

if [[ ! -d build ]]; then
 mkdir build
fi

cd build
rm -rf *

cmake -D CMAKE_BUILD_TYPE=RELEASE \\
      -D CMAKE_INSTALL_PREFIX=install \\
      -D OPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.5.0/modules \\
      -D OPENCV_ENABLE_NONFREE=ON \\
      ..

make -j16

make install

编译：

chmod +x build.sh
./build.sh

编译完成后，opencv的头文件、库等文件安装到opencv-4.5.0/build/install目录下。
