POSITIONING METHOD, DEVICE, AND ELECTRONIC APPARATUS

Abstract:

A positioning method, a device, and an electronic apparatus. The method comprises: obtaining a GNSS position of a vehicle; obtaining standard positioning data around a road where the vehicle is located; obtaining laser point cloud data around the road where the vehicle is located; extracting to-be-matched positioning data around the road; forward simulating a motion state of the vehicle based on sampling positions corresponding to the vehicle at a previous moment, to obtain sampling positions at a current moment; converting the to-be-matched positioning data into a coordinate system corresponding to the standard positioning data; matching the to-be-matched positioning data with the standard positioning data to obtain a probability that the vehicle is located at each sampling position at the current moment; and obtaining a position of the vehicle based on the probability that the vehicle is located at each sampling position at the current moment.
