opencv4.1.0+cuda10.0安装

Install OpenCV=4.1.0

1. (For CUDA 10.0 only) CUDA 9.x should have no problem. Video decoder is deprecated in CUDA 10.0. To handle this, download NVIDIA VIDEO CODEC SDK and copy the header files to your cuda path (/usr/local/cuda-10.0/include/ for example). Note that you may have to do as root

   unzip Video_Codec_SDK_9.0.20.zip
   cp Video_Codec_SDK_9.0.20/include/nvcuvid.h /usr/local/cuda-10.0/include/
   cp Video_Codec_SDK_9.0.20/include/cuviddec.h /usr/local/cuda-10.0/include/
   cp Video_Codec_SDK_9.0.20/Lib/linux/stubs/x86_64/libnvcuvid.so /usr/local/cuda-10.0/lib64/libnvcuvid.so.1

2. Obtain required packages for building OpenCV 4.1.0

   sudo apt-get install -y liblapack-dev libatlas-base-dev
   sudo apt-get install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev
   sudo apt-get install -y software-properties-common
   sudo add-apt-repository ppa:jonathonf/ffmpeg-4
   sudo apt update
   sudo apt install -y ffmpeg

    

3. Obtain OpenCV 4.1.0 and its extra modules (optflow, etc.) by

   cd third_party
   wget -O OpenCV-4.1.0.zip wget https://github.com/opencv/opencv/archive/4.1.0.zip
   unzip OpenCV-4.1.0.zip
   wget -O OpenCV_contrib-4.1.0.zip https://github.com/opencv/opencv_contrib/archive/4.1.0.zip
   unzip OpenCV_contrib-4.1.0.zip

    

4. Build OpenCV 4.1.0 from scratch (due to some custom settings)

   cd opencv-4.1.0
   mkdir build && cd build
   cmake -DCMAKE_BUILD_TYPE=Release \
    -D WITH_CUDA=ON \
    -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.1.0/modules/ \
    -D WITH_TBB=ON \
    -D BUILD_opencv_cnn_3dobj=OFF \
    -D CUDA_HOST_COMPILER:FILEPATH=/usr/bin/gcc-5 \
    -D BUILD_opencv_dnn=OFF \
    -D BUILD_opencv_dnn_modern=OFF \
    -D BUILD_opencv_dnns_easily_fooled=OFF \
    -D OPENCV_ENABLE_NONFREE=ON ..
   make -j
   sudo make install

   自己在安装过程中发现的一个非常重要的问题，cuda编译需要的gcc版本和opencv编译需要的gcc版本要求不一样，会导致出错！

类似 #include "features2d/test/test_detectors_regression.impl.hpp"的问题，需要给出从opencv-4.1.0/modules/xfeatures2d/test/下对应文件的绝对路径。

另一个，缺少boostdesc_bgm.i等文件，这里可以提供下载。
