terminal input
apt update
apt install -y cmake g++ unzip//安装cmake,g++,unzip
Then unzip opencv-4.0.0.zip, opencv_contrib-4.0.0.zip
unzip opencv-4.0.0.zip
unzip opencv_contrib-4.0.0.zip
enter directory
cd opencv-4.0.0
mkdir build
cd build
cmake in the build path
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.0.0/modules ..
When it shows Configuring done
After Generating done
Start compiling:
make
This is because some files have not been downloaded, not only boostdesc_bgm.i here, but also
boostdesc_bgm_bi.i
boostdesc_bgm_hd.i
boostdesc_binboost_064.i
boostdesc_binboost_128.i
boostdesc_binboost_256.i
vgg_generated_120.i
vgg_generated_64.i
vgg_generated_80.i
vgg_generated_48.i
Solution: Download the missing files and copy them to the \opencv_contrib-4.0.0\modules\xfeatures2d\src directory
Then compile make
Put the file under opencv/modules/features2d/test/
test_descriptors_invariance.impl.hpp
test_descriptors_regression.impl.hpp
test_detectors_invariance.impl.hpp
test_detectors_regression.impl.hpp
test_invariance_utils.hpp
Copy it to the opencv_contrib-4.0.0/modules/xfeatures2d/test/ file.
Will opencv_contrib-4.0.0/modules/xfeatures2d/test/test_features2d.cpp under the file
#include "features2d/test/test_detectors_regression.impl.hpp"
#include "features2d/test/test_descriptors_regression.impl.hpp"
Change to:
#include "test_detectors_regression.impl.hpp"
#include "test_descriptors_regression.impl.hpp"
Will be under the opencv_contrib-4.0.0/modules/xfeatures2d/test/test_rotation_and_scale_invariance.cpp file
#include "features2d/test/test_detectors_invariance.impl.hpp"
#include "features2d/test/test_descriptors_invariance.impl.hpp"
Change to:
#include "test_detectors_invariance.impl.hpp"
#include "test_descriptors_invariance.impl.hpp"
compile again
