Abstract: An encoded substrate to be filmed by a camera device for generating an image is provided. The encoded substrate includes a plurality of grids arranged in a form of two-dimensional array, wherein each grid includes a first pattern and a second pattern not overlapped with each other. The first pattern corresponds to a first-dimensional encoded value, and the second pattern corresponds to a second-dimensional encoded value. The image is processed by a processor for scanning the plurality of grids. In a first-dimensional direction, the processor outputs a first coordinate according to at least two first patterns corresponding to at least two consecutive grids among the plurality of grids. In a second- dimensional direction, the processor outputs a second coordinate according to at least two second patterns corresponding to at least two consecutive grids among the plurality of grids.
