基于opencv在摄像头ubuntu根据视频获取



基于opencv在摄像头ubuntu根据视频获取

1  工具 原料

    平台 ：UBUNTU12.04

    安装库  Opencv-2.3    

   

2  安装编译执行步骤

   安装编译opencv-2.3  參考http://blog.csdn.net/xiabodan/article/details/23547847

  提前下载OPENCV源代码包

  官方：http://sourceforge.net/projects/opencvlibrary/files/opencv-unix/

 我的：http://download.csdn.net/detail/xiabodan/7176253

             

2

sudo apt-get update sudo apt-get upgrade sudo apt-get install build-essential libgtk2.0-dev libjpeg-dev libtiff4-dev libjasper-dev libopenexr-dev cmake python-dev python-numpy python-tk libtbb-dev libeigen2-dev yasm libfaac-dev libopencore-amrnb-dev libopencore-amrwb-dev libtheora-dev libvorbis-dev libxvidcore-dev libx264-dev libqt4-dev libqt4-opengl-dev sphinx-common texlive-latex-extra libv4l-dev libdc1394-22-dev libavcodec-dev libavformat-dev libswscale-dev

             解压源代码包

3	tar -xvf OpenCV-2.4.1.tar.bz2

4	cd OpenCV-2.4.1

1	mkdir build cmake配置MAKEFILE

2

cd build

3	cmake -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 ..

        然后进行make

1

make

2	sudo make install

        配置opencv

    

1	sudo gedit /etc/ld.so.conf.d/opencv.conf

        Add the following line at the end of the file(it may be an empty file, that is ok) and then save it: 在opencv.conf中加入下面路径

1	/usr/local/lib

           sudo ldconfig

1	sudo gedit /etc/bash.bashrc

        Add these two lines at the end of the file and save it: 在bash.bashrc中加入下面环境变量

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

2	export PKG_CONFIG_PATH

        sudo   reboot 重新启动电脑

注意：一定要提前安装V4L等等库,不然编译能过。执行的时候没有画面。

   

3  測试代码

编译

g++ cameraCaptrue.cpp  -o  cameraCap `pkg-config --libs --cflags opencv`

生成文件cameraCap

执行  採集成功

./cameraCap

cameraCaptrue.cpp

#include<stdio.h>
#include<math.h>
#include "highgui.h"
#include <cv.h>
#include <opencv2/opencv.hpp>
#include <opencv2/highgui/highgui.hpp>

//#include <cvaux.h>
//#include <highguihighgui_c.h>
//#include <core	ypes_c.h>
//#include <photophoto_c.h>
//#include <imgprocimgproc_c.h>
//#include <photophoto

using namespace cv;


int main( int argc, char** argv )
{
	printf("I am start 
");
	VideoCapture cap(0); // open the default camera
	if(!cap.isOpened())  // check if we succeeded
		return -1;

	printf("%f, %f
",cap.get(CV_CAP_PROP_FRAME_WIDTH),cap.get(CV_CAP_PROP_FRAME_HEIGHT));
	cap.set(CV_CAP_PROP_FRAME_WIDTH, 320);
	cap.set(CV_CAP_PROP_FRAME_HEIGHT, 240);
	cap.set(CV_CAP_PROP_FPS, 15);
	printf("%f, %f
",cap.get(CV_CAP_PROP_FRAME_WIDTH),cap.get(CV_CAP_PROP_FRAME_HEIGHT));
	Mat src_gray;
	cvNamedWindow( "video", CV_WINDOW_AUTOSIZE );

	while(1)
	{
		Mat frame;
		cvWaitKey(10);
		cap >> frame;
		imshow("video", frame);
	}


	return 0;
}

接下来移植到zedboard上去
