This message is to announce the availability of patternMaker, a pattern
making tool for use with ARToolKit.
PatternMaker is available at
The patternMaker program automatically creates large numbers of target
patterns for the ARToolkit.
The ARToolkit normally requires custom drawn target patterns that are hand
trained using the toolkit and a camera. We want the capability of
generating large numbers of target patterns and training them
automatically. Furthermore, we want the patterns to be as clear as possible
to provide the highest performance recognition in the toolkit.
We have created the patternMaker program, which generates grids of black
and white squares. The restriction is that the grids cannot be rotationally
symmetric with itself or other grids in the group, else the ARToolkit won't
be able to extract orientation from the target pattern. The training files
are automatically generated from the patterns.
This project is supported by the NSF STC for Computer Graphics and
Visualization and collaborative NSF/NIH projects with the Scripps Research
Institute and the University of Washington. The ARToolkit is publicly
available from the University of Washington
