INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND COMPUTER-READABLE STROAGE MEDIUM

摘要

A pattern light projection unit which stores information on pattern light including information on line patterns projects pattern light including line patterns having at least two lines and at least one reference line pattern serving as a reference of the line patterns on an object in accordance with the information on pattern light. An image pickup unit captures an image of the object to which the pattern light is projected. An information processing apparatus detects the reference line pattern and the line patterns from the captured image, and establishes correspondence between the information on the line patterns stored in the pattern light projection unit and the line patterns detected from the captured image in accordance with the topological positional relationship between the detected reference line pattern and the line patterns so as to identify the line patterns.
