ERROR ESTIMATION METHOD, KINEMATIC ANALYSIS METHOD, ERROR ESTIMATION DEVICE, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide an error estimation method, etc., capable of reducing a processing load and accurately estimating an error in the index representing the state of a mobile entity by using a signal from a positioning satellite.;SOLUTION: An error estimation method includes the steps of: calculating, with prescribed timing in a cycle of movement accompanying the locomotion of a mobile entity, a coordinate conversion matrix between a first coordinate system based on a first sensor attached to the mobile entity and a second coordinate system based on the mobile entity; when the detection result of a second sensor for receiving a signal from the positioning satellite is obtained, converting one of the bearing angle of the mobile entity based on the detection result of the first sensor and the bearing angle of the mobile entity based on the detection result of the second sensor by using the coordinate conversion matrix; and estimating, with prescribed timing after the timing at which the detection result of the second sensor is obtained, an error in the index representing the state of the mobile entity by using a difference between the converted bearing angle and the other bearing angle.;COPYRIGHT: (C)2016,JPO&INPIT
