    • 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.
    • 提供了一种识别绝对坐标的系统和方法。 绝对坐标识别系统包括:图形记录介质,其中每个单元被图示化,并且将预定的微码分配给由图示化单元的每个布置形成的图案; 图案感测单元,通过感测图案识别微码; 以及信号处理单元,从感测图案计算图案记录介质上的图案感测单元的位置。 通过构造图案记录介质的更简单的图案,绝对坐标识别系统及其方法能够使不具有高分辨率的成像系统和图像传感器识别图案。
