Abstract

The invention provides a traffic element recognition method and device, equipment and a computer readable storage medium, and relates to the map field and the artificial intelligence field. The method comprises the following steps: carrying out traffic element detection on an obtained road image to obtain traffic elements to be classified; predicting to-be-classified features and a plurality of space potential field features corresponding to the plurality of traffic element templates from the to-be-classified traffic elements and the plurality of obtained traffic element templates, wherein the space potential field features represent the attraction or rejection degree between the to-be-classified traffic elements and the traffic element template; searching a matching element template corresponding to the to-be-classified traffic elements from a plurality of traffic element templates according to the plurality of space potential field features and the to-be-classified features; and determining a category corresponding to the matching element template as a target category of the to-be-classified traffic elements. According to the invention, the accuracy of traffic element identification can be improved.

Description

technical field [0001] The present application relates to the field of maps and artificial intelligence, and in particular to a traffic sign recognition method, device, equipment and computer-readable storage medium. Background technique [0002] Traffic elements (such as traffic signs, monitoring facilities, etc.) can prompt which roads have traffic restrictions, for example, which road sections need speed limits, which road sections have illegal photos, etc. Traffic element recognition refers to identifying the traffic elements in the collected road images with the help of artificial intelligence technology, so as to use the identified traffic elements to update map data or perform automatic driving. [0003] In related technologies, a recognition model is trained using labeled data, and the recognition model is used to recognize traffic elements in collected road images. However, due to the unbalanced samples of different types of traffic elements in the labeled data and...
