基于opencv在攝像頭ubuntu根據視頻獲取

1? 工具 原料

??? 平臺 ：UBUNTU12.04

??? 安裝庫? Opencv-2.3????

???

2? 安裝編譯執行步驟

?? 安裝編譯opencv-2.3? 參考http://blog.csdn.net/xiabodan/article/details/23547847

? 提前下載OPENCV源代碼包

? 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

????????? ?? 解壓源代碼包

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 ..

??????? 然后進行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中加入下面路徑

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中加入下面環境變量

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

2	export?PKG_CONFIG_PATH

??????? sudo?? reboot 重新啟動電腦

注意：一定要提前安裝V4L等等庫,不然編譯能過，執行的時候沒有畫面。

???

3? 測試代碼

編譯

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

生成文件cameraCap

執行? 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 cameraif(!cap.isOpened()) // check if we succeededreturn -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; }

接下來移植到zedboard上去
