Title:
LINE-OF-SIGHT DIRECTION CALIBRATION DEVICE, LINE-OF-SIGHT DIRECTION CALIBRATION METHOD, AND LINE-OF-SIGHT DIRECTION CALIBRATION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/135281
Kind Code:
A1
Abstract:
The invention comprises: a calibration information acquisition unit (101) that acquires, for at least one observation target for calibration, three-dimensional coordinates indicating the position of each observation target for calibration; a sample acquisition unit (102) that acquires a plurality of samples indicating the line-of-sight direction of a user; a calibration model generating unit (103) that, on the basis of the three-dimensional coordinates indicating the position of each observation target for calibration and the samples indicating the line-of-sight direction of the user in a state where the user is observing each observation target for calibration, generates a plurality of calibration models indicating three-dimensional coordinates to be candidates for the position of the user; and a calibration parameter calculation unit (104) that, on the basis of the generated calibration models, calculates a calibration parameter.
