说明：

• 介绍如何在NX上安装opencv带CUDA

步骤：

• 新建脚本，vim buildOpencv.sh
• 内容如下：

if [ "$#" -ne 1 ]; then
    echo "Usage: $0 <Install Folder>"
    exit
fi
folder="$1"
user="ubuntu"
passwd="ubuntu"

echo "** Remove OpenCV4.1 first"
#sudo apt-get purge *libopencv*

echo "** Install requirement"
sudo apt-get update
sudo apt-get install -y build-essential cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
sudo apt-get install -y libgstreamer1.0-dev libgstreamer-plugins-base1.0-dev
sudo apt-get install -y python2.7-dev python3.6-dev python-dev python-numpy python3-numpy
sudo apt-get install -y libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev
sudo apt-get install -y libv4l-dev v4l-utils qv4l2 v4l2ucp
sudo apt-get install -y curl
sudo apt-get update

echo "** Download opencv-4.1.1"
cd $folder
curl -L https://github.com/opencv/opencv/archive/4.1.1.zip -o opencv-4.1.1.zip
curl -L https://github.com/opencv/opencv_contrib/archive/4.1.1.zip -o opencv_contrib-4.1.1.zip
unzip opencv-4.1.1.zip 
unzip opencv_contrib-4.1.1.zip 
cd opencv-4.1.1/

echo "** Building..."
mkdir release
cd release/
cmake -D WITH_CUDA=ON -D ENABLE_PRECOMPILED_HEADERS=OFF  -D CUDA_ARCH_BIN="7.2" -D CUDA_ARCH_PTX="" -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib-4.1.1/modules -D WITH_GSTREAMER=ON -D WITH_LIBV4L=ON -D BUILD_opencv_python2=ON -D BUILD_opencv_python3=ON -D BUILD_TESTS=OFF -D BUILD_PERF_TESTS=OFF -D BUILD_EXAMPLES=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..
