Information processing device, program, and pattern code

Abstract

To provide an information processing device, a program, and a pattern code that can quickly identify a position within a pattern. [Solution] According to one aspect of the present invention, an information processing device is provided. This information processing device comprises a projection image generation unit, a decoding unit, and a phase identification unit. The projection image generation unit is configured to generate a projection image based on predetermined pattern information and to output the generated projection image to a projection device. The projection image includes a clock pattern and a data pattern based on the pattern information. The decoding unit is configured to decode the data pattern into values ​​based on an image captured by an imaging device that captures an object. The image captured is an image of an object in which a projection image is projected by the projection device. The phase identification unit is configured to identify the phase of each part of the object based on the values ​​and the pattern information.
