DEVICE, SYSTEM AND METHOD FOR CALCULATION OF SUBJECT AREA

摘要

PROBLEM TO BE SOLVED: To provide a subject area calculation device capable of calculating the area of an object domain of a subject, only by an image including a simple mark.

SOLUTION: The device includes: a reading-out means 12 for reading out a first image including the subject and the mark imaged by a first image capturing apparatus, and a second image including the subject and the mark imaged from an angle different from that of the first image capturing apparatus by a second image capturing apparatus; an image capturing apparatus coordinate estimation means 13 for estimating a value of a three-dimensional coordinate of a first position of the first image capturing apparatus, and a value of a three-dimensional coordinate of a second position of the second image capturing apparatus; a specific point coordinate estimation means 14 for estimating a value of each three-dimensional coordinate of a plurality of specific points included in the subject based on the first position and the second position; and an area calculation means 15 for calculating the area of the subject based on the value of each three-dimensional coordinate of the plurality of specific points. The mark has a two-dimensional shape including three or more pointers.
