安装依赖项

sudo apt install libavcodec-dev libavformat-dev libswscale-dev libavresample-dev
sudo apt install libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
sudo apt install libxvidcore-dev x264 libx264-dev libfaac-dev libmp3lame-dev libtheora-dev 
sudo apt install libfaac-dev libmp3lame-dev libvorbis-dev

sudo apt install libopencore-amrnb-dev libopencore-amrwb-dev

 编译过程

将opencv_contrib-4.4.0移到opencv-4.4.0

 cp -r opencv_contrib-4.4.0 opencv-4.4.0

cd opencv-4.4.0
mkdir build
cd build

cmake -DCMAKE_BUILD_TYPE=RELEASE -DCMAKE_INSTALL_PREFIX=~/opencv44/ -DBUILD_JAVA=OFF -DOPENCV_EXTRA_MODULES_PATH=../opencv_contrib-4.4.0/modules -DWITH_CUDA=1 -DENABLE_FAST_MATH=1 -DCUDA_FAST_MATH=1 -DWITH_CUBLAS=1 -DOPENCV_GENERATE_PKGCONFIG=ON -DWITH_GSTREAMER=ON -DCUDA_GENERATION=Pascal ..

编译安装的地址是~/opencv44/，需要修改一下

make -j
make install

添加环境变量

vim ~/.bashrc

export PKG_CONFIG_PATH=/home/cxzx/opencv44/lib/pkgconfig
export LD_LIBRARY_PATH=/home/cxzx/opencv44/lib


source ~/.bashrc

 

make -j遇到的问题

问题1

/home/cxzx/opencv-4.4.0/opencv_contrib-4.4.0/modules/xfeatures2d/src/vgg.cpp:490:41: fatal error: vgg_generated_120.i: No such file or directory
/home/cxzx/opencv-4.4.0/opencv_contrib-4.4.0/modules/xfeatures2d/src/boostdesc.cpp:654:37: fatal error: boostdesc_bgm.i: No such file or directory

解决方法

我提供百度云盘中的文件boostdesc.tar.gz解压

cd /home/cxzx/boostdesc
cp * ../opencv-4.4.0/opencv_contrib-4.4.0/modules/xfeatures2d/src/

 

问题2

fatal error: opencv2/xfeatures2d.hpp: No such file or directory

然后将opencv-4.4.0/opencv_contrib-4.4.0/modules/xfeatures2d/test/test_features2d.cpp中的

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

 

再将opencv-4.4.0/opencv_contrib-4.4.0/modules/xfeatures2d/test/test_rotation_and_scale_invariance.cpp中的

 

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

 

问题3

fatal error: opencv2/xfeatures2d.hpp: No such file or directory

cd /home/cxzx/opencv-4.4.0
vim CMakeLists.txt

添加 

INCLUDE_DIRECTORIES("/home/cxzx/opencv-4.4.0/opencv_contrib-4.4.0/modules/xfeatures2d/include")

解决这三个问题就可以编译成功了
