Abstract

The invention discloses a vehicle positioning method and device, electronic equipment and a computer storage medium, and relates to the technical field of navigation positioning. According to the specific implementation scheme, the method comprises the following steps: acquiring road network information, periodically positioning a vehicle to obtain a positioning position, determining a target roadsection in which the vehicle travels in the current period from a plurality of road sections indicated by the road network information according to the positioning position obtained by positioning ineach historical period, and correcting the positioning position in the current period according to the target road section to obtain the positioning position in the target road section. According tothe method, the current driving road section is predicted through historical positioning, and the positioning position is corrected according to the predicted current driving road section, so that thecondition of large positioning information fluctuation is avoided, and the positioning accuracy is improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to the field of navigation and positioning technology, and in particular to a vehicle positioning method, device, electronic equipment and computer storage medium. Background technique [0002] Positioning is an extremely important part of vehicle navigation, and people's requirements for positioning and navigation accuracy are getting higher and higher. [0003] However, GPS positioning information is inaccurate or even lost, for example, elevated scenes, parking lots, and tunnels. Underground roads or dense forests, etc., the GPS positioning information will have a large drift, ranging from tens of meters to hundreds of meters, resulting in low positioning accuracy. Contents of the invention [0004] Provided are a vehicle positioning method, device, electronic equipment and computer storage medium. [0005] According to the first aspect, a vehicle positioning meth...
