Fedora12配置OpenCV开发环境

///////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////

//源码安装cmake

1.下载cmake源码cmake-2.6.2.tar.gz，http://www.cmake.org/cmake/resources/software.html

2.编译安

tar xvf cmake-2.6.2.tar.gzcd cmake-2.6.2///如果本机上不存在cmake，则：./bootstrapmakemake install//如果本机上存在cmake，想安装一个新版本，则：cmake .makemake install

//源码安装opencv

1.下载opencv，http://www.opencv.org.cn/index.php/Download

2.安装opencv-2.3.0

tar -xvf OpenCV-2.3.0.tar.bz2cd OpenCV-2.3.0/mkdir releasecd releasecmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D BUILD_PYTHON_SUPPORT=ON ..makesudo make intall

3.添加库路径

sudo vim /etc/ld.so.conf.d/opencv.conf/usr/local/lib(添加内容)

4.更新系统库

$sudo ldconfig

5.设置环境变量

export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:$PKG_CONFIG_PATH

6.测试

cd samples/cchmod +x build_all.sh./build_all.sh./facedetect --cascade="/usr/local/share/opencv/haarcascades/haarcascade_frontalface_alt.xml" --scale=1.5 lena.jpg

可以看到以下图片,说明opencv 安装正常

//编译执行第一个C实现的OpenCV程序

//OpenCV参考手册：http://www.opencv.org.cn/index.php

1.程序代码show.c

#include "cv.h"#include "highgui.h"int main(int argc, char **argv){    IplImage* pImage;    if(argc==2 && (pImage=cvLoadImage(argv[1],1))!=0)    {        cvNamedWindow("Image",1);        cvShowImage("Image",pImage);        cvWaitKey(0);        cvDestroyWindow("Image");        cvReleaseImage(&pImage);        return 0;    }    return -1;}

2.编译代码

[kang@Gala opencv]$ gcc show.c -o showshow..c:1:16: error: cv.h: No such file or directoryshow..c:2:21: error: highgui.h: No such file or directoryshow..c: In function ‘main’:show..c:6: error: ‘IplImage’ undeclared (first use in this function)show..c:6: error: (Each undeclared identifier is reported only onceshow..c:6: error: for each function it appears in.)show..c:6: error: ‘pImage’ undeclared (first use in this function)show..c:7: error: subscripted value is neither array nor pointer

由于highgui中采用了C++，所以一定要用g++编译才可以，编译命令如下：

//直接编译链接g++ `pkg-config --cflags opencv` -o show show.c `pkg-config --libs opencv`//先编译再链接:g++ `pkg-config --cflags opencv` -c show.cg++ `pkg-config --libs opencv` -o show show.o

再次编译，出现下述错误信息：

[kang@Gala opencv]$ g++ `pkg-config --cflags opencv` -c show.cPackage opencv was not found in the pkg-config search path.Perhaps you should add the directory containing `opencv.pc'to the PKG_CONFIG_PATH environment variableNo package 'opencv' found

解决方法是将/usr/local/lib/pkgconfig中的opencv.pc拷贝到/usr/lib/pkgconfig中，否则程序将无法编译

sudo cp /usr/local/lib/pkgconfig/opencv.pc  /usr/lib/pkgconf

//OpenCV2.3.0 with Python2.6

//OpenCV2.1 Python Reference : http://opencv.willowgarage.com/documentation/python/index.html

1.程序代码show.py

import sysimport cvif __name__ == '__main__':    image=cv.LoadImage("1.jpg")    cv.NamedWindow("mywin")    cv.ShowImage("mywin",image)    cv.WaitKey(0)

2.执行程序show.py

[kang@Gala opencv]$ python show.pyTraceback (most recent call last):  File "show.py", line 2, in <module>    import cvImportError: No module named cv

3.解决办法

[kang@Gala opencv]$ sudo cp /usr/local/lib/python2.6/dist-packages/cv.so /usr/lib/python2.6/site-packages
