sudo apt-get update sudoapt-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

Extracting source code Packages

3	tar  -xvf OpenCV-2.4.1. tar .bz2

4	CD  opencv-2.4.1

1	mkdir  build cmake configuration 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 ..

Then make

1

make

2	sudomakeinstall

Configure OPENCV

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

        add The following line at the end of the File (it may be a empty file, that's OK) and then save it: Add the following path in opencv.conf

1	/usr/local/lib

sudoldconfig

1	sudo  gedit/etc/ Code class= "Functions" >bash .BASHRC

        Add These-lines at the end of the file and SA ve it: Add the following environment variable in BASH.BASHRC

1	pkg_config_path= $PKG _config_path:/usr/ local /lib/pkgconfig

2	exportPKG_CONFIG_PATH

sudo reboot restart your computer

Note: Be sure to pre-install v4l and so on library, or compile can be over, the execution of the time without pictures.

3 Test Code

Compile

g++ cameraCaptrue.cpp-  o  cameracap ' pkg-config--libs--cflags OpenCV '

Generate File Cameracap

Perform a collection success

./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 


Then transplant to Zedboard.
