INFORMATION PROCESSING APPARATUS, INFORMATION PROCESSING METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To make it possible to accurately determine a correspondence between projection coordinates and imaging coordinates even when a target object to which patterns are projected has a small observation luminance and is affected by noise.SOLUTION: An information processing apparatus comprises: image acquisition means that acquires an image obtained by photographing a target object on which patterns having bright parts and dark parts are projected by projection means; detection means that detects the positions of boundaries between bright and dark of the patterns; application means that refers to the positions of boundaries to apply labels to pixels in the image according to the luminance of the pixels; and correspondence relationship derivation means that derives a correspondence relationship between the positions of the patterns on a projection surface of the projection means and the positions of the patterns on the acquired image on the basis of the applied labels.SELECTED DRAWING: Figure 1
