ABSTRACT:
A two-dimensional code detector detecting a two-dimensional code including a plurality of position identifying patterns and an information pattern and generating control information for an object provided with the two-dimensional code, the two-dimensional code detector includes: an image input unit which inputs an acquired image obtained by an image pickup of the object; a pattern detection unit which detects position identifying patterns within the acquired image; a position/posture calculation unit which calculates position/posture information indicating a position and posture of the two-dimensional code in a three-dimensional space based on a two-dimensional position of the position identifying patterns detected by the pattern detection unit; a decoding device which decodes the information pattern; and a control information generating unit which generates the control information based on the decoded information decoded by the decoding device and the position/posture information calculated by the position/posture calculation unit.
