Abstract

A generating unit generates a 3D model of an object based on pair images obtained for the same object. An extracting unit extracts plural first feature points from a to-be-synthesis 3D model and plural second feature points from a synthesis 3D model. An obtaining unit obtains a coordinate conversion parameter based on the plural first feature points and second feature points. A converting unit converts a coordinate of the synthesis 3D model in a coordinate in the coordinate system of the to-be-synthesis 3D model using the coordinate conversion parameter. A synthesizing unit synthesizes all converted synthesis 3D models with the to-be-synthesis 3D model, and unifies feature points. A storing unit stores the synthesized 3D model of the object and information on the unified feature points in a memory card, etc. The stored data is used in an AR process.

Dependent claims

An AR process apparatus comprising:

an image obtaining unit that obtains a set of images which comprises two or more images having a parallax for an object;
a generating unit that generates a 3D model of the object based on the set of images obtained by the image obtaining unit;
an extracting unit which (a) selects a 3D model of the object initially generated by the generating unit as a to-be-synthesis 3D model, (b) extracts a plurality of first feature points from the to-be-synthesis 3D model, (c) selects a 3D model of the object subsequently generated by the generating unit as a synthesis 3D model, and (d) extracts a plurality of second feature points from the synthesis 3D model;
an obtaining unit that obtains, based on (i) the plurality of first feature points of the to-be-synthesis 3D model and (ii) the plurality of second feature points of the synthesis 3D model extracted by the extracting unit, a coordinate conversion parameter that converts a coordinate of the synthesis 3D model into a coordinate in a coordinate system of the to-be-synthesis 3D model;
a converting unit that converts the coordinate of the synthesis 3D model into the coordinate in the coordinate system of the to-be-synthesis 3D model using the coordinate conversion parameter obtained by the obtaining unit;
a synthesizing unit which (a) generates a synthesized-3D model of the object by synthesizing a plurality of synthesis 3D models, whose coordinates have been converted by the converting unit, with the to-be-synthesis 3D model, and (b) unifies the feature points;
and
a storing unit that stores (a) the synthesized-3D model of the object generated by the synthesizing unit and (b) information indicating the unified feature points in a memory device.
