Map data production method, related device and system

Abstract

The invention discloses a map data production method, a related device and a system. The map data production method comprises the following steps: according to each collected picture and a corresponding track, carrying out image identification on each collected picture; determining attribute information of each map element in the picture according to the identification result, the attribute information comprising at least one of the type, the content and the geographic position; and fusing the determined attribute information of each map element with existing map data to generate new map data.According to the method, the content shot by the picture and the track during picture collection are combined, automatic extraction of all element data in the picture is achieved in an automatic recognition mode, the production efficiency of the map data is improved, and meanwhile the accuracy of the map element data is relatively guaranteed. And when correct recognition cannot be performed, thepictures and the image recognition result are processed through a manual data operation module, so that the manual recognition process is increased, and the accuracy of the map element data is furtherensured.

Description

technical field [0001] The invention relates to the technical field of geographic information, in particular to a method for producing map data, a related device and a system. Background technique [0002] The collection and production of electronic map data can use data collection vehicles to collect data through field collection, and manually mark the collected data, etc. The process of electronic map data collection will generate a huge number of real-scene pictures. In the usual data processing process, it is necessary to manually read the real-scene pictures one by one, such as marking various elements related to the road in the real-scene picture, such as lanes and lanes. , traffic signs, surveillance cameras (electronic eyes), etc. content, location, etc., and then hand over the manually marked information to the cartographic personnel to complete the production and supplement of electronic map data. [0003] Since the electronic map data has considerable requirement...

AI Technical Summary

Problems solved by technology

[0003] Since the electronic map data has considerable requirements on the accuracy of the data, and the construction and layout of roads and various facilities on the roads need to comply with various corresponding specifications, combined with the complexity of the actual roads, the above-mentioned map reading process has great impact on personnel. The knowledge reserves, familiarity and past experience requirements are very high, but even if the requirements can be met, the manual reading and labeling method still has the problems of high labor costs, low processing efficiency, and difficulty in ensuring accuracy
