An information processing apparatus generates pattern data including a plurality of measurement lines, and a reference line which has a plurality of intersection points with the plurality of measurement lines, respectively, and has a shape that is defined in an interval between the intersection points by a specific feature, captures an image of an object onto which projection pattern light, based on the generated pattern data, is projected, extracts the intersection points from the captured image, and obtains information, concerning the shape with a specific feature in the interval between the intersection points on the reference line in the captured image, as identification information used to identify the measurement lines. |
