Title (EN) INERTIAL SENSOR CALIBRATION METHOD
(FR) PROCÉDÉ D'ÉTALONNAGE DE CAPTEUR INERTIEL
(KO) 관성센서 캘리브레이션 방법
Abstract:
(EN) The present invention relates to an inertial sensor calibration method and, more particularly, to a method which enables accurate dead reckoning (DR) positioning by calculating a scale factor of an inertial sensor by using an indoor map of a high-definition map, an entry/exit link of map data, or GNSS heading information at the time of entering or exiting a building parking lot including a turning path, in order to calibrate a scale factor of an inertial sensor even in a shaded region in which a GNSS signal is not received.
(FR) La présente invention concerne un procédé d'étalonnage de capteur inertiel et, plus particulièrement, un procédé qui permet un positionnement de point estimé simple (PES) précis par calcul d'un facteur d'échelle d'un capteur inertiel à l'aide d'une carte intérieure d'une carte haute définition, d'une liaison d'entrée/de sortie de données de carte, ou d'informations de cap GNSS au moment de l'entrée ou de la sortie d'un parc de stationnement d'un bâtiment comprenant une piste de virage, afin d'étalonner un facteur d'échelle d'un capteur inertiel même dans une région ombrée dans laquelle un signal GNSS n'est pas reçu.
(KO) 본 발명은 관성센서 캘리브레이션 방법에 관한 것으로서, 특히 GNSS 신호가 수신되지 않는 음영지역에서도 관성센서의 스케일 팩터를 캘리브레이션하기 위하여 회전이 있는 건물 주차장에 진출입시의 GNSS 헤딩 정보, 지도 데이터의 진출입 링크 또는 정밀지도의 실내지도를 이용하여, 관성센서의 스캐일 팩터를 계산하여 정밀한 DR(DeadReckoning) 측위가 가능하도록 하는 것에 관한 것이다.
