Title:
POSITION COORDINATE DERIVATION DEVICE, POSITION COORDINATE DERIVATION METHOD, POSITION COORDINATE DERIVATION PROGRAM, AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/166424
Kind Code:
A1
Abstract:
The purpose of this disclosure is to make it possible to ascertain the coordinates of equipment. In this disclosure, a processor acquires two or more images obtained through the imaging of equipment and an object (S101); the position coordinates and actual size of the equipment and the size of the object are acquired from a database (S104); using the relationship between the distances from cameras that imaged the two or more images to the equipment and the magnifications of the equipment in the two or more images compared to the actual size of the equipment, the processor calculates the distances from the cameras that imaged the two or more images to the object (S108); and the processor uses the calculated distances to derive the position coordinates of the object (S109).
