Zusammenfassung:	Disclosed are a device and a method for estimating a position of a pedestrian. According to one embodiment of the present invention, the device for estimating the position of the pedestrian comprises: an input unit for receiving sensor data on a moving pedestrian from an inertial sensor; a first estimation part for estimating a posture by using an initial posture and a state variable estimated from the sensor data; and a second estimation part for estimating a position of the pedestrian from the first position to the second position by using walking, stride, and moving direction of the pedestrian estimated from the posture. Therefore, the present invention is capable of accurately estimating the position of the pedestrian. 보행자 위치 추정 장치 및 방법이 개시된다. 본 발명의 일실시예에 따른 보행자 위치 추정 장치는 관성 센서로부터 이동하는 보행자에 대한 센서데이터를 입력 받는 입력부; 상기 센서데이터로부터 추정한 초기 자세와 상태 변수를 이용하여 자세를 추정하는 제1 추정부 및 상기 자세로부터 추정한 보행자의 걸음, 보폭 및 이동방향을 이용하여 제1 위치부터 제2 위치까지의 보행자의 위치를 추정하는 제2 추정부를 포함한다.
