Title:
TRACKER CALIBRATION DEVICE, TRACKER CALIBRATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2020/090042
Kind Code:
A1
Abstract:
Provided are a tracker calibration device, tracker calibration method, and program that make it possible to precisely calibrate a plurality of types of trackers without measuring the relative positions of the trackers beforehand. A tracker data acquisition unit (50) acquires a plurality of items of first tracker data indicating the position of a first tracker expressed using a first coordinate system. The tracker data acquisition unit (50) acquires a plurality of items of second tracker data indicating the position and orientation of a second tracker expressed using a second coordinate system. On the basis of the plurality of items of first tracker data and the plurality of items of second tracker data, a parameter estimation unit (58) estimates parameter values for converting the positions expressed using the second coordinate system into expressions in the first coordinate system and estimates the relative position of the second tracker in relation to the position of the first tracker.
