Title:
MOBILE BODY AND LOCAL POSITION ESTIMATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/179960
Kind Code:
A1
Abstract:
This mobile body comprises: an external environment sensor (106) which senses the space in the periphery of the mobile body and periodically outputs sensor data; a storage device (108) which stores map data; a positioning device (110) which, using the sensor data and the map data, carries out a process of estimating the position of the mobile body and sequentially outputs position estimation values; and a computation circuit (120). When the positioning device is to commence the process of estimating the position of the mobile body at a second time point after having outputted the position estimation value for the mobile body at a first time point, the computation circuit references the distance and direction of the movement of the mobile body between the first time point and the second time point to correct the position estimation value at the first time point accordingly, and supplies the positioning device with the corrected estimation value which serves as an initial position of the position of the mobile body at the second time point.
