Abstract

The embodiment of the invention discloses a method and device for updating a matching relationship between a navigation map and a perception image. The method comprises the steps of obtaining the current position of a vehicle provided by a preset positioning device, and correcting the elevation of the vehicle provided by the preset positioning device based on lane line information corresponding tothe current position in the navigation map; arranging and combining the traffic sign groups, meeting the set distance requirement with the current position, in the navigation map and the perception image collected by a camera so as to determine a target traffic sign matched with the position from the navigation map and the perception image; and correcting the pose of the vehicle in the navigationmap according to the position of the target traffic sign, and updating the matching relationship between the navigation map and the perception image based on the corrected elevation and the pose of the vehicle. By the adoption of the technical scheme, the problem that the positioning precision is not high when a consumption-level preset positioning device is used is solved, and the high-precisionpositioning effect also can be achieved through the consumption-level preset positioning device.

Description

technical field [0001] The invention relates to the technical field of automatic driving, in particular to a method and device for updating the matching relationship between a navigation map and a perception image. Background technique [0002] In the field of autonomous driving, high-precision positioning is crucial. In recent years, the achievements of deep learning and other technologies have greatly promoted the development of image semantic segmentation and image recognition, which provides a solid foundation for high-precision maps and high-precision positioning. [0003] In the positioning scheme based on high-precision maps, when an unmanned vehicle enters the high-precision map for the first time, it needs to obtain a global and accurate location information for initialization, and then use the high-precision map for precise positioning, that is, absolute position accuracy up to centimeter level. However, in consumer-grade equipment, such as single-point GPS (Glob...
