Allgemein
In unserem Eyetracking Projekt versuchen wir ein "Low cost mobile head monted eyetracking" zusammenzusetellen, um an der Hochschule Luzern ein Forschungslabor einzurichten.
The aim of the Eyetracking Project is to provide a "low cost mobile head monted eyetracking" system for use in a research loboratory.
Installation
This guide is for installation on OSX 10.4.x systems. (Installation on OSX 10.5 will need some modifications.) You'll need following software:
Install Apple XTools / XCode
Download and install svnX
Download and install InsomniaX
Download and install Darwinports and then in the Terminal:
- sudo port install pkgconfig
Download Openeyes (alternativ Link) and unpack in $HOME/devel/ .
To install libdc1394, open the Terminal and enter:
- cd $HOME/devel
- svn co https://libdc1394.svn.sourceforge.net/svnroot/libdc1394/trunk/libdc1394/ -r 537 libdc1394r537
- (I use the revision 537 for OSX 10.4.X, OSX 10.5.X should be able to work with head)
- cd libdc1394r537
- autoreconf -i -s
Download Opencv to $HOME/devel, apply the following patch (it permits you to see the value of a slider in the gui) and build the frameworks
- cd $HOME/opencv
- patch -p0 < window_carbon.patch
- ./make_frameworks.sh

The OpenCV.framework will be located in $HOME/devel
Now it's time to create the xcode project for Openeyes.
