(原)ubuntu 下安装opencv
在ubuntu 10.04下安装opencv，步骤如下：
1、找到opencv的依赖包
$ sudo apt-cache search opencv libcv-dev - development files for libcv libcv4 - computer vision library libcvaux-dev - development files for libcvaux libcvaux4 - computer vision extension library libhighgui-dev - development files for libhighgui libhighgui4 - computer vision GUI library opencv-doc - OpenCV documentation and examples python-opencv - Python bindings for the computer vision library harpia - Image Processing/Computer Vision Automatic Prgm. Tool
2、安装opencv
$ sudo apt-get install libcv-dev libcv4 libcvaux-dev libcvaux4 libhighgui-dev libhighgui4 opencv-doc harpia
3、在CodeBlocks中配置opencv
点击Settings ->Compiler and debugger settings，在Linker settings的Other linker options：里添加 -lcv -lcxcore -lhighgui。在Search directories -> Compier 下添加目录 /usr/include/opencv，在右边的Linker标签下添加目录/usr/lib
4、示例代码
/*
* 例示1：用于从磁盘加载并在屏幕上显示一幅图像
*/
#include <iostream>
#include <highgui.h>
using namespace std;
int main( int argc, char *argv[] )
{
if( argc < 2) {
cout<< "Usage:" << argv[0] << "<image_name>" << endl;
return 1;
}
IplImage *img = cvLoadImage( argv[1] );
if( !img ) {
cout<< argv[1] << "image load error." << endl;
return 1;
}
cvNamedWindow( "Exampe1: LoadImage", CV_WINDOW_AUTOSIZE );
cvShowImage( "Example1", img );
cvWaitKey( 0 );
cvReleaseImage( &img );
cvDestroyWindow( "Example1" );
return 0;
}
（要运行此示例，需要设置项目参数，具体如下：Project -> set programs' arguments...，在Program arguments下输入要显示的图片的名字。）
