window10 編譯OpenCV4.2.0 OpenCV_Contrib4.2.0

參考上篇在ubuntu上編譯，現在在window上編譯，道理一樣 https://blog.csdn.net/u011171361/article/details/106303216

1.準備工作

1.下載所需文件，並在opencv-4.2.0建立build文件，將opencv_contrib-4.2.0改成opencv_contrib並移入opencv-4.2.0目錄，否則會報無法打開包括文件: “features2d/test/test_detectors_invariance.impl.hpp”: No such file or directory

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

2.cmake配置

3.配置選項

BUILD_opencv_world   	            勾選
WITH_TBB				            勾選
WITH_OPENMP				            勾選
OPENCV_ENABLE_NONFREE               勾選
BUILD_EXAMPLES                      勾選

OPENCV_EXTRA_MODULES_PATH     
配置爲:F:\opencv\opencv-4.2.0\opencv_contrib\modules(注意這路徑是作者的路徑)

4.使用Vs打開解決方案 點擊運行 - debug版X64

 遇到無法打開包括文件: “features2d/test/test_detectors_invariance.impl.hpp”: No such file or directory

解決辦法：從F:\opencv\opencv-4.2.0\modules\features2d\test目錄下複製以下文件到F:\opencv\opencv-4.2.0\opencv_contrib\modules\xfeatures2d\test

從F:\opencv\opencv-4.2.0\opencv_contrib\modules\xfeatures2d\test目錄下複製以下文件到F:\opencv\opencv-4.2.0\modules\features2d\test目錄下

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.生成庫
