Abstract

The invention discloses a vehicle positioning optimization method, a vehicle positioning optimization device, equipment and a storage medium and belongs to the field of automatic driving and can alsobe applied to the field of autonomous parking. According to the embodiments of the invention, the method is applied to electronic equipment. A vehicle carries a fusion positioning system and a perception positioning system which are used for determining a fusion vehicle pose and a sensing lane line. The method comprises the following steps that: target positioning information associated with optimized positioning information is acquired, wherein the target positioning information is determined through the electronic equipment and at least one positioning system mounted on the vehicle; an optimization model about the optimized positioning information and the target positioning information is constructed according to a preset positioning approaching strategy; the target positioning information is inputted into the optimization model, and the optimized positioning information in the optimization model is solved, so that the optimized positioning information can be outputted; and if the optimized positioning information passes verification, the optimized positioning information is sent to the vehicle so as to control the vehicle to drive according to the optimized positioning information.

Description

technical field

[0001] The present application relates to the technical field of data processing, in particular to the technology of autonomous driving. Background technique

[0002] With the maturity of artificial intelligence technology, autonomous driving technology has also developed rapidly. The automatic driving technology includes a positioning system. The positioning system is responsible for locating the pose of the autonomous vehicle, and it can also locate the pose of the lane line.

[0003] The positioning systems in the prior art mainly include: GPS positioning systems, perception positioning systems, and the like. Among them, the positioning accuracy of the GPS positioning system is low, and the positioning accuracy is about two to ten meters, which cannot meet the lane-level positioning requirements. Although the perception positioning system can perform lane-level positioning, there is a large error and the positioning accuracy is inaccurate.
