Abstract

The invention discloses a method, device, equipment and medium for extracting road data. The method comprises: according to the road section identification ID obtained in the road section information table, querying the road section and road correspondence table, obtaining the road ID corresponding to the road section ID; querying the road name of the road ID in the road name table, and obtaining the correspondence between the road section ID and the road name Relation; integrate based on the corresponding relationship between the road section ID and the road name, and obtain the integration result of the road section ID and the road name; integrate the result of the integration of the road section ID and the road name according to the road name again, and obtain the road section ID set of each road name; The traffic sign of the road section divides the section ID set of the road name into an uplink section ID set and a downlink section ID set to obtain the whole road data. According to the road data extraction method, device, equipment and computer-readable storage medium provided by the present invention, the data with the whole road as a unit can be obtained to meet business requirements.

Description

technical field [0001] The present invention relates to the field of computers, in particular to a method, device, equipment and computer-readable storage medium for extracting road data. Background technique [0002] With the increasing popularity of Internet electronic map services and driving navigation services, the public's requirements for road data continue to increase. The provision of accurate, high-quality, and complete road data is of great importance for the display of Internet electronic maps and the application of vehicle navigation electronic maps. Significance. [0003] At present, the smallest unit of basic road data collected independently by business and provided by map suppliers is a discrete road segment, and there is no concept of a complete road. When searching for a business, it is generally necessary to obtain data in units of the entire road, including the name of the road, the direction of the road, and information about a collection of road-relat...
