System and method of detecting absolute coordinates
Abstract:
A system and method of recognizing absolute coordinates are provided. The absolute coordinate recognition system includes: a pattern recording medium in which each cell is diagrammatized, and a predetermined microcode is allocated to the pattern formed by each arrangement of the diagrammatized cells; a pattern sensing unit recognizing the microcode by sensing the pattern; and a signal processing unit calculating the position of the pattern sensing unit on the pattern recording medium, from the sensed pattern. By constructing the simpler patterns of the pattern recording medium, the absolute coordinate recognition system and method therefor enable imaging system and image sensor with not-high resolutions to recognize the patterns.
