Eeldused

Luba failis /etc/apt/sources.list seal vaikimisi väljakommenteeritud repositooriumid multiverse ja universe

Käivita järgnevad korraldused

sudo apt-get -y install pkg-config cmake qtcreator build-essential libgtk-3-dev libjpeg62-dev  
sudo apt-get -y install libjasper-dev libpng12-dev zlib1g-dev openexr ffmpeg 
sudo apt-get -y libgstreamer0.10-dev libv4l-dev libxine-dev libunicap2-dev 
sudo apt-get -y libavformat-dev libswscale-dev subversion qtcreator  libv4l-dev
sudo apt-get -y install libavformat-dev libswscale-dev


Lae alla OpenCV Unix versioon 2.4.3


cd ~
wget http://downloads.sourceforge.net/project/opencvlibrary/opencv-unix/2.4.3/OpenCV-2.4.3.tar.bz2
tar jxf OpenCV-2.4.3.tar.bz2
cd OpenCV-2.4.3


Tõmba viimane vers robotvision projektist

svn co http://robot.itcollege.ee/svn/vision/botmaster2012/

OpenCV kompileerimine

  • lae alla opencv stabiilse haru algteks http://opencv.willowgarage.com/wiki/ Dowloads alt;
  • paki tulemus lahti
  • sisene lahtipakkimisel loodud kausta
  • loo alamkaust release
  • sisene kausta relase ja käivita
cmake .. -DWITH_JPEG=OFF -DCMAKE_BUILD_TYPE=RELEASE  -DCMAKE_CXX_FLAGS="-march=native -O3 -ftree-vectorize"  -DCMAKE_C_FLAGS="-march=native -O3 -ftree-vectorize"

PS: võib muuta ka march=native cmake konfifailist, kui tegu on robotile mineva asusega

PPS: JPEG=OFF on hea, et kaamerast tuleb stream ei oleks MJPEG.

Kui nutetakse v4lv1 puudumise üle a'la OpenCV-2.2.0/modules/highgui/src/ cap_v4l.cpp:217:28: fatal error: linux/videodev.h: No such file or directory

Siis paigalda v4lv1 dev pakk

sudo apt-get install libv4l-dev

Ja muuta modules/highgui/src/cap_v4l.cpp

rida #include <linux/videodev.h> asendada reaga #include <libv4l1-videodev.h> Probleemide korral uue ubuntuga: - http://tech.groups.yahoo.com/group/OpenCV/message/79758
