Problems solved by technology
[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. Poor positioning accuracy between locations
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. Accuracy of Location Data Provided

The embodiment of the present invention discloses a positioning data processing method, the method comprising: acquiring vehicle motion information corresponding to a target vehicle, and determining the target vehicle at the position to be measured based on the vehicle motion information and prior probability distribution The first motion probability distribution; match the measured local road surface reference object with the global road surface reference object in the navigation map, and according to the matching result and the prior probability distribution, determine that the target vehicle is in the The first measurement probability distribution on the position; the fusion of the first motion probability distribution and the first measurement probability distribution to obtain the posterior probability distribution of the target vehicle at the position to be measured; based on the The posterior probability distribution determines the optimal target position information corresponding to the target vehicle. By adopting the invention, the lateral positioning accuracy of the vehicle can be improved, and the accuracy of 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 ...
