Document Type and Number:
WIPO Patent Application WO/2021/144874
Kind Code:

Abstract:
An imaging range inferring apparatus (1) that comprises an image data processing unit (110) that acquires image data that has been captured by a camera device (21) and generates image data to which object name labels have been appended, a reference data generation unit (120) that uses geographical information to establish regions within a prescribed imageable distance from an inference location at which the camera device (21) is provided and generates reference data to which object name labels have been appended, and an imaging range inferring unit (130) that calculates coincidence ratios by comparing feature values indicated by the regions of the object name labels of the image data and feature values indicated by the regions of the object name labels of the reference data and infers that the regions of the reference data that correspond to the image data are the imaging range of the camera device (21).
