Title:
INFORMATION PROCESSING DEVICE, INFORMATION PROCESSING METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2022/201848
Kind Code:
A1
Abstract:
An information processing device (30) has a depth estimation unit (32) and a depth correction unit (33). The depth estimation unit (32) estimates, on the basis of the result of time-of-flight measurement of a reference light (PL), the depth of a projection position at which the reference light (PL) is projected and a non-projection position that is offset from the projection position. The depth correction unit (33) extracts, as an error component, the estimated value of the depth of a position to be measured that is obtained when the reference light (PL) is projected to a position offset from the position to be measured of a subject (SU). The depth correction unit (33) removes the error component from the estimated value of the depth of the position to be measured that is obtained when the reference light (PL) is projected to the position to be measured.
