  • Publication number: 20210049375
    Abstract: A first onboard device-mounted on a measuring vehicle—includes a LiDAR, and it receives a reflected wave which is laser emitted to and reflected by a road surface and recognizes a curve start location of a lane line on the road surface based on reflected wave intensity. The first onboard device-transmits road surface information including the recognized curve start location to a server device via a network. The server device gives information indicating the curve start location to information regarding the lane line in map information based on the road surface information. A second onboard device mounted on a vehicle acquires the information regarding the lane line from the server device and estimates a current location by comparing a curve start location of the lane line recognized by a LiDAR and the information indicating the curve start location of the lane line acquired from the server device.

  • Publication number: 20210035448
    Abstract: An objective of the present invention is to provide a method for processing surrounding information which enables improvement of accuracy for estimation of a current position of a moving body. The objective is achieved by detecting light transparent region information of the surrounding information acquired by a sensor in a detection step, wherein the light transparent region information corresponds to a light transparent region. Further, in a generation step, information after removal is generated by removing the light transparent region information from the surrounding information. In this manner, a current position for a travelling vehicle can be estimated with the information after removal. The estimation accuracy can be improved by omitting the information about the light transparent region for which the acquired information may vary.
