Document Type and Number:
WIPO Patent Application WO/2021/095095
Kind Code:
A1
Abstract:
A camera calibration device (10) according to the present disclosure comprises: a skeletal frame detection unit (11) that detects the two-dimensional skeletal frame structure of a person on the basis of a two-dimensional image captured by a camera; a vector calculation unit (12) that, on the basis of the two-dimensional skeletal frame structure detected by the skeletal frame detection unit (11), calculates a skeletal frame vector indicating the direction and magnitude of the skeletal frame of the person in the two-dimensional image; and a parameter calculation unit (13) that calculates a camera parameter of the camera on the basis of the skeletal frame vector calculated by the vector calculation unit (12).
