Title:
THREE-DIMENSIONAL RECONSTRUCTION DEVICE, THREE-DIMENSIONAL RECONSTRUCTION METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2023/073971
Kind Code:
A1
Abstract:
This three-dimensional reconstruction program (1) is provided with: an input unit (11) which inputs a panorama image (21) of a target indoor space, and three-dimensional coordinates (22) interpolated so as to connect corners to be imaged, shown on a drawing of the indoor space; an image encoding unit (12) which extracts image feature values from the panorama image (21); a shape encoding unit (13) which extracts three-dimensional shape feature values from the interpolated three-dimensional coordinates (22); a link calculation unit (14) which generates feature values that link image feature values and three-dimensional shape feature values; an image coordinate decoding unit (15) which generates boundary image coordinates by decoding the linked feature values; and a three-dimensional reconstruction unit (16) which performs three-dimensional reconstruction of the indoor space on the basis of the boundary image coordinates.
