本文详细介绍了如何在Ubuntu系统上卸载旧版OpenCV并安装新版OpenCV3.0.0的过程，包括必要的依赖包安装、源码编译配置、路径设置及测试代码示例。

ubuntu卸载opencv并重装opencv3.0.0
一、卸载opencv2.4.9： Going to the "build" folder directory of opencv from terminal, and execute the following：

$ sudo make uninstall
$ cd ..
$ sudo rm -r build
$ sudo rm -r /usr/local/include/opencv2 /usr/local/include/opencv /usr/include/opencv /usr/include/opencv2 /usr/local/share/opencv /usr/local/share/OpenCV /usr/share/opencv /usr/share/OpenCV /usr/local/bin/opencv* /usr/local/lib/libopencv*

这一步可能有error
下面执行如下操作：

sudo apt-get –purge remove opencv-doc opencv-data python-opencv

二、安装opencv，去优快云下载opencv3.0.0和ippicv_linux_20141027.tgz（http://download.youkuaiyun.com/detail/yunlong782/8940743）。

install essential packages
[compiler] sudo apt-get install build-essential
[required] sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
[optional] sudo apt-get install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

使用cmake-gui安装，首先安装cmake和cmake-qt-gui

$ sudo apt-get install cmake cmake-qt-gui
解压opencv3.0.0，并进入目录，建立build目录并进去build目录打开终端，并输入：$ cmake-gui
在source 目录里添加：文件目录如（../../../opencv-3.0.0.0-beta），在build目录添加build目录（如：../../../opencv-3.0.0.0-beta/build）,在CUDA_GENERATION 选择Kepler（我的显卡型号：gtx 980m）
configure，此时会处错误，原因是由于ippicv_linux_20141027.tgz不正确。把下载好的ippicv_linux_20141027.tgz替换掉出错路径下的ippicv_linux_20141027.tgz即可。重新configure
generate
进入build目录 $ make -j8
7.在build目录下 $ sudo make install
写入opencv路径：sudo sh -c 'echo "usr/local/lib" > /etc/ld.so.conf.d/opencv.conf'
sudo ldconfig

三、测试opencv是否装好

1.创建工作目录
$ mkdir ~/opencv-lena
$ cd ~/opencv-lena
$ gedit DisplayImage.cpp

编译如下代码

#include <stdio.h>
#include <opencv2/opencv.hpp>
using namespace cv;
int main(int argc, char** argv )
{
    if ( argc != 2 )
    {
        printf("usage: DisplayImage.out <Image_Path>\n");
        return -1;
    }
    Mat image;
    image = imread( argv[1], 1 );
    if ( !image.data )
    {
        printf("No image data \n");
        return -1;
    }
    namedWindow("Display Image", WINDOW_AUTOSIZE );
    imshow("Display Image", image);
    waitKey(0);
    return 0;
}

创建CMake文件
$ gedit CMakeLists.txt
写入如下内容

cmake_minimum_required(VERSION 2.8)
project( DisplayImage )
find_package( OpenCV REQUIRED )
add_executable( DisplayImage DisplayImage.cpp )
target_link_libraries( DisplayImage ${OpenCV_LIBS} )
