Problems solved by technology

At present, it is usually necessary for the staff to drag and drop the electronic map interface to manually interpret the intersections to be retrieved from the massive map data, which has the problem of high cost and low efficiency of intersection retrieval
Especially when the types of intersections to be retrieved are complex or the number of intersections is scarce in the actual road network, the retrieval difficulty is even greater

Abstract

The application discloses an intersection retrieval method, device, equipment and storage medium, and relates to the technical fields of artificial intelligence and intelligent transportation. The specific implementation plan is: obtain the fork characteristics of the intersection to be retrieved input by the user on the interactive interface; perform intersection retrieval according to the fork characteristics of the intersection to be retrieved and the fork characteristics of candidate intersections in the road network; wherein, the fork characteristics include intersections The relationship between the number of fork roads and the angle of fork roads. It can reduce the intersection retrieval cost and improve retrieval efficiency and accuracy. A new way of thinking is provided for intersection retrieval.

Description

technical field [0001] This application relates to the field of computer technology, in particular to the field of artificial intelligence and intelligent transportation technology. Specifically, it relates to an intersection retrieval method, device, device and storage medium. Background technique [0002] In the process of urban planning, there is a need to retrieve various types of urban intersections in the city. At present, it is usually necessary for staff to drag the electronic map interface to manually interpret the intersection to be retrieved from the massive map data, and there are problems of high cost and low efficiency of intersection retrieval. Especially when the type of intersection to be retrieved is complex or the number is rare in the actual road network, the retrieval is more difficult. SUMMARY OF THE INVENTION [0003] The present disclosure provides an intersection retrieval method, device, device and storage medium. [0004] According to a first ...
