window10 编译OpenCV4.2.0 OpenCV_Contrib4.2.0

参考上篇在ubuntu上编译，现在在window上编译，道理一样 https://blog.csdn.net/u011171361/article/details/106303216

1.准备工作

1.下载所需文件，并在opencv-4.2.0建立build文件，将opencv_contrib-4.2.0改成opencv_contrib并移入opencv-4.2.0目录，否则会报无法打开包括文件: “features2d/test/test_detectors_invariance.impl.hpp”: No such file or directory

2.opencv420_boostdesc_bgm_vgg_generated里面的全部放在opencv_contrib/modules/xfeatures2d/src ，下载缺失的文件：https://download.csdn.net/download/u011171361/12456484

2.cmake配置

3.配置选项

BUILD_opencv_world   	            勾选
WITH_TBB				            勾选
WITH_OPENMP				            勾选
OPENCV_ENABLE_NONFREE               勾选
BUILD_EXAMPLES                      勾选

OPENCV_EXTRA_MODULES_PATH     
配置为:F:\opencv\opencv-4.2.0\opencv_contrib\modules(注意这路径是作者的路径)

4.使用Vs打开解决方案 点击运行 - debug版X64

 遇到无法打开包括文件: “features2d/test/test_detectors_invariance.impl.hpp”: No such file or directory

解决办法：从F:\opencv\opencv-4.2.0\modules\features2d\test目录下复制以下文件到F:\opencv\opencv-4.2.0\opencv_contrib\modules\xfeatures2d\test

从F:\opencv\opencv-4.2.0\opencv_contrib\modules\xfeatures2d\test目录下复制以下文件到F:\opencv\opencv-4.2.0\modules\features2d\test目录下

test_descriptors_invariance.impl.hpp
test_descriptors_regression.impl.hpp
test_detectors_invariance.impl.hpp
test_detectors_regression.impl.hpp
test_features2d.cpp
test_invariance_utils.hpp
test_rotation_and_scale_invariance.cpp

/////////////////////////////////////////////////////////
修改test_features2d.cpp文件下的

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

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

//////////////////////////////////////////////////////////
修改test_rotation_and_scale_invariance.cpp文件下的

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

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

5.生成库
