我刚刚在Ubuntu 14.04上安装了OpenCV 3.0。它的工作原理。

根据官方教程，安装OpenCV。#!/bin/bashd

#https://help.ubuntu.com/community/OpenCV

version="$(wget -q -O - http://sourceforge.net/projects/opencvlibrary/files/opencv-unix | egrep -m1 -o '\"[0-9](\.[0-9]+)+' | cut -c2-)"

echo "Installing OpenCV" $version

mkdir OpenCV

cd OpenCV

echo "Removing any pre-installed ffmpeg and x264"

sudo apt-get -qq remove ffmpeg x264 libx264-dev

echo "Installing Dependenices"

sudo apt-get -qq install libopencv-dev build-essential checkinstall cmake pkg-config yasm libjpeg-dev libjasper-dev libavcodec-dev libavformat-dev libswscale-dev libdc1394-22-dev libxine2-dev libgstreamer0.10-dev libgstreamer-plugins-base0.10-dev libv4l-dev python-dev python-numpy libtbb-dev libqt4-dev libgtk2.0-dev libfaac-dev libmp3lame-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev x264 v4l-utils ffmpeg cmake qt5-default checkinstall

echo "Downloading OpenCV" $version

wget -O OpenCV-$version.zip http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/$version/opencv-"$version".zip/download

echo "Installing OpenCV" $version

unzip OpenCV-$version.zip

cd opencv-$version

mkdir build

cd build

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_TBB=ON -D BUILD_NEW_PYTHON_SUPPORT=ON -D WITH_V4L=ON -D INSTALL_C_EXAMPLES=ON -D INSTALL_PYTHON_EXAMPLES=ON -D BUILD_EXAMPLES=ON -D WITH_QT=ON -D WITH_OPENGL=ON ..

make -j2

sudo checkinstall

sudo sh -c 'echo "/usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'

sudo ldconfig

echo "OpenCV" $version "ready to be used"

使用以下代码进行测试：import cv2

img = cv2.imread("/home/xiao/Desktop/test.png")

cv2.imshow("opencv",img)

cv2.waitKey(0)

cv2.destroyAllWindows()
