Title:
METHOD FOR ESTIMATING TRAFFIC LIGHT ARRANGEMENT INFORMATION BY USING MULTIPLE OBSERVATION INFORMATION
Document Type and Number:
WIPO Patent Application WO/2022/255678
Kind Code:
A1
Abstract:
The present invention relates to a method for estimating traffic light arrangement information by using multiple observation information, and comprises the steps of: collecting, in a travelling step of each of a plurality of vehicles, observation data regarding fixed objects near a road; classifying the observation data according to classification classes defined for the respective fixed objects; clustering the observation data on the basis of a location within the same classification class; sequentially selecting the observation data according to an observation condition and an observation feature; analyzing the observation data by applying a numerical analysis model thereto; verifying observation reliability on the basis of the result of the analysis; if the observation data passes the verification, determining an object location with respect to at least one of the fixed objects; if a fixed object corresponds to a traffic light, estimating, on the basis of the observation data, a type of corresponding traffic light and the number of lamps of the corresponding traffic light; detecting and matching, from the observation data, a lighting situation for each of the lamps of the corresponding traffic light; and if the matching is successful, determining a lamp configuration and arrangement of the corresponding traffic light.
