Positioning data processing method

Abstract

Embodiments of the invention disclose a positioning data processing method. The method comprises the steps of obtaining vehicle movement information corresponding to a target vehicle and determining afirst movement probability distribution, on a to-be-measured position, of the target vehicle on the basis of the vehicle movement information and a prior probability distribution; matching a measuredlocal pavement reference object with a global pavement reference object in a navigation map and determining a first measurement probability distribution, on the to-be-measured position, of the targetvehicle according to the matching result and the prior probability distribution; fusing the first movement probability distribution with the first measurement probability distribution to obtain a posterior probability distribution, on the to-be-measured position, of the target vehicle; and determining optimum target position information corresponding to the target vehicle on the basis of the posterior probability distribution. By adoption of the positioning data processing method, the lateral positioning precision for the vehicles can be enhanced and the correctness of the positioning data can be improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a positioning data processing method. Background technique [0002] At present, the initial positioning accuracy of the positioning system is usually 5-10 meters. For self-driving cars, when positioning, there will be a large lateral positioning error in the navigation map, that is, the positioning position displayed on the navigation map is different from the real position. Positioning accuracy between locations is poor. For example, the target vehicle is actually in the second lane during automatic driving, but the navigation map shows that the target vehicle is in the first lane. The accuracy of the location data provided. Contents of the invention [0003] The embodiment of the present invention provides a positioning data processing method, which can improve the lateral positioning accuracy of the vehicle and improve the accuracy of the positioning data. [0004] One ...
