発明の名称 (英語) MARKER GENERATION DEVICE, THREE-DIMENSIONAL MEDIUM, INFORMATION PROCESSING SYSTEM, MARKER GENERATION METHOD, AND RECORDING MEDIUM NEW 新技術説明会
発明の概要(英語) This marker generation device, which generates a display marker to be displayed on a three-dimensional object, comprises: a data generation unit that generates data to be an M-sequence; a partial marker generation unit that generates a partial marker by arranging a first color pattern and a second color pattern according to the bits constituting the data; and a display marker generation unit that generates the display marker by combining the partial marker and an inversion marker formed by inverting the first color and the second color in the partial marker.
従来技術、競合技術の概要(英語) BACKGROUND ART
A so-called M-sequence (Maximum length sequence, maximum period sequence or a maximum linear length sequence) based on, for detecting the position of the object using known techniques for generating a marker.
For example, first, the bits constituting the M-series as shown (bit), x 1 in the direction of the two-dimensional barcode is generated. Next, the same y direction to generate two-dimensional bar code 1, a projector, the direction of the generated 2 barcode is superimposed. Then, the display position of a bar code read, with respect to the total area of the bar code 2 read the two-dimensional coordinate position can be specified are known (for example, see Patent Document 1).
In addition, the three-dimensional object in order to recognize a bar code, the same code has been known a method of arranging a plurality of (for example, see Patent Document 2).
