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/article/1495659.html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
[code]sudo
apt-get upgrade
sudo 
apt-get
[code]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 <highgui\highgui_c.h>
//#include <core\types_c.h>
//#include <photo\photo_c.h>
//#include <imgproc\imgproc_c.h>
//#include <photo\photousing namespace cv;int main( int argc, char** argv )
{
printf("I am start \n");
VideoCapture cap(0); // open the default camera
if(!cap.isOpened())  // check if we succeeded
return -1;printf("%f, %f\n",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\n",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
