Abstract

The invention discloses a multi-scale vector road data matching and updating method and a device thereof and computer equipment, and the method comprises the steps: determining a similarity measurement index which comprises at least one of a corner cut direction difference, an area accumulation difference and a comprehensive median distance; preprocessing road network data to be matched according to a preset processing mode, taking data obtained by preprocessing as a matching unit, and determining a matching object and a corresponding matched object; determining a matching relationship between the matching object and the matched object based on a similarity measurement index in combination with geometric feature similarity and a spatial scene structure similarity measurement mode; and determining a road change entity according to the matching relationship, and transmitting the road change entity from the large-scale road network database to the small-scale road network database to realize linkage updating of vector road data of various scales. By adopting the method, the road network data updating efficiency can be improved.

Description

technical field [0001] The present invention relates to the technical field of road network data update, more specifically, to a method, device and computer equipment for matching and updating vector road data. Background technique [0002] Road data is the most frequently updated object in the process of urban development, and its real-time and accurate update is an important topic in many GIS application research circles. At present, the automatic matching and update application based on multi-source and multi-scale vector road data is a key technology to realize the information fusion, change update and establishment of multi-expression spatial database of vector road data. Although this technology can realize the effective fusion and matching of vector road data information, it is mainly oriented to surface entities, and there are relatively few studies on the update of line entities, and there is a lack of reasonable and effective solutions to the linkage update of mult...
