Title:
POSITION ESTIMATION DEVICE, POSITION ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2019/176020
Kind Code:
A1
Abstract:
Provided are a position estimation device, a position estimation method, and a program capable of accurately estimating the position of a tracker, while resulting in lower power consumption. An estimation result storage unit (50) stores an estimation result of the position of a tracker (12). An acceleration data acquisition unit (52) repeatedly acquires acceleration data indicating the acceleration of the tracker (12) from a sensor that detects the acceleration of the tracker (12). An estimation result update unit (56) updates the estimation result, on the basis of the estimation result of the position of the tracker stored in the estimation result storage unit (50) and on the basis of the latest acceleration data having been acquired. A speed information acquisition unit (54) acquires information of the speed of the tracker (12). When the information of the speed has been acquired by the speed information acquisition unit (54), the estimation result update unit (56) updates the estimation result of the position of the tracker (12) stored in the estimation result storage unit (50), on the basis of the information of the speed and the latest acceleration data having been acquired.
