Problems solved by technology

[0003] The existing urban road network data is an important data basis for accurate restoration and reconstruction of the real world. However, the road information of the existing urban road network is seriously lacking. For example, the free OSM (OpenStreetMap) data currently available, some roads The network only has the latitude and longitude coordinates of vertices, but does not have detailed road attribute informatio

Embodiment Construction

[0051] Specific embodiments of the present disclosure will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0052] Such as figure 1 Shown is a flow chart of a method for generating traffic road network attribute information provided according to an embodiment of the present disclosure. The methods include:

[0053] Step S1, acquiring the traffic road network data of the target area. For example, OSM (OpenStreetMap) can provide map data with a wide range and new data free of charge. In one embodiment of the present disclosure, traffic road network data can be obtained by acquiring OSM data in a target area. First get the OSM data. There are many ways to obtain OSM data: you can directly download the OpenStreetMap closest to the target area on the official websit...

Abstract

The invention relates to a traffic network attribute information generation method and device, a storage medium and an electronic device, and the method comprises the steps: obtaining the traffic network data of a target region; establishing a road information dictionary of the target area, wherein the road information dictionary at least comprises road point coordinates and road names; calculating a matching relationship between a target road in the target area traffic network and a reference road in the road information dictionary; and matching the attribute information of the reference roadin the road information dictionary with the corresponding target road in response to matching of the target road and the reference road. The device comprises a target road network data acquisition module, an information search module, a road information dictionary module and a first matching module. According to the invention, attribute information addition of a road network in a given longitudeand latitude range can be realized, and the accuracy is high. Through the process of adding the attribute information of the original traffic network data from nothing to nothing, a foundation is laidfor optimization of a subsequent method, addition of new attributes and 3D reconstruction of a virtual city.

Description

technical field [0001] The present disclosure relates to the field of traffic road network data processing, in particular to a method, device, storage medium and electronic equipment for generating traffic road network attribute information. Background technique [0002] Urban 3D modeling technology restores a full-detailed real city panorama in a virtual world with rich 3D information, and brings practical benefits to people in multiple fields such as navigation, urban planning, smart city construction, security, facility management, and disaster management. and considerable benefits. [0003] The existing urban road network data is an important data basis for accurate restoration and reconstruction of the real world. However, the road information of the existing urban road network is seriously lacking. For example, the free OSM (OpenStreetMap) data currently available, some roads The network only has the latitude and longitude coordinates of vertices, but does not have de...
