Title:
POSITION CORRECTION DEVICE, DISPLACEMENT AMOUNT EXTRACTION SYSTEM, AND POSITION CORRECTION METHOD
Document Type and Number:
WIPO Patent Application WO/2024/029057
Kind Code:
A1
Abstract:
The present invention manages, with high precision, the alignment of three-dimensional data. This position correction device comprises: an invariable region extraction unit that extracts, as pre-displacement three-dimensional data, three-dimensional data representing pre-displacement position information, extracts, as post-displacement three-dimensional data, three-dimensional data representing post-displacement position information, extracts, as post-displacement image data, image data corresponding to the post-displacement three-dimensional data, and extracts, as an invariable region, a non-displaced image region in the post-displacement image data; and a correction unit that, using as a reference only position information corresponding to the invariable region, performs a correction so as to align the post-displacement three-dimensional data with the pre-displacement three-dimensional data.
