Description

Technical field

[0001] The present invention relates to the technical field of electronic maps, and in particular to a road sign recognition method and device, medium and terminal. Background technique

[0002] An electronic map, that is, a digital map, is a map that is stored and consulted digitally using computer technology. It is a map that uses the collected map data to present it in a paperless manner. The application of electronic map is very extensive, for example, it can be applied to navigation or cruise process.

[0003] The electronic map can include road signs on the road surface. Recognizing the road signs on the road surface is a common way to generate road signs in the electronic map.

[0004] The accuracy of existing road sign recognition methods needs to be improved. Summary of the invention

[0005] The technical problem solved by the embodiments of the present invention is to improve the accuracy of road signs.

[0006] In order to solve the above technical problem...
