Ubuntu 16.04中安装OpenCV 2.4.11

2016-07-26 6:32:32 暂无评论月上柳梢 linux系统 808

16.04中安装OpenCV 2.4.11参考网址如下：

1 预先安装一些软件：

sudo apt-get install build-essential cmake libgtk2.0-dev pkg-config python-dev python-numpy libavcodec-dev libavformat-dev libswscale-dev

2 去管网下载opencv压缩包

3 解压压缩包到某文件夹（用windows习惯了，直接右键提取到此处。。。）

4 command中cd到该解压缩的文件夹中，然后创建build文件夹 mkdir build

5 进入build目录 cd build

6 编译opencv源码

cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local ..

7 安装

sudo make install

测试：

1. 写helloworld.cpp

using namespace cv;#include int main( int argc, char** argv ){    if( argc != 2 )//判断参数是否是两个    {        printf( " No image data \n " );        return -1;    }    char* imageName = argv[1];    Mat image = imread( imageName, 1 );//读入图片;    if(  !image.data)//判断是否有数据    {        printf( " No image data \n " );        return -1;    }    namedWindow( imageName, CV_WINDOW_AUTOSIZE );    imshow( imageName, image );//显示图片    waitKey(0);    return 0;}

2. 写cmake的makefile，即CMakeLists.txt

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

3. 进入该文件夹，创建build，mkdir build

4. 之后：

cmake .make

得到可执行文件 helloworld

5. 拷贝一张图像到该可执行文件文件夹中，输入

./helloworld 11.jpg

显示图像，说明安装成功

ps：

1. 之前未使用步骤1，结果编译没错，运行后，提示

OpenCV Error: Unspecified error (The function is not implemented. Rebuild the library with windows, GTK+ 2.x or Carbon support. If you are on Ubuntu or Debian, install libgtk2.0-dev and pkg-config, then re-run cmake or configure script) in cvNamedWindow, file /home/XXX/file/program/opencv2411/modules/highgui/src/window.cpp, line 483 terminate called after throwing an instance of 'cv::Exception'
