Region marking method and device and electronic equipment

Abstract

The embodiment of the invention discloses a region marking method, device and electronic device, wherein the method comprises: establishing a building information model geographic information system BIM-GIS model corresponding to a target road segment, wherein the BIM-GIS model is based on the target Determining the BIM model of the road segment and the GIS data; acquiring a point cloud model of the target road segment; comparing the first road surface elevation corresponding to the BIM-GIS model with the second road surface elevation corresponding to the point cloud model; There is an area where the difference between the first road surface elevation and the second road surface elevation is greater than a preset threshold, and the area is marked. The implementation of the embodiments of the present invention helps to determine the area where the road is diseased in time to improve the accuracy and reliability of the road disease determination.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to an area marking method, device and electronic equipment. Background technique [0002] Building Information Modeling (Building Information Modeling, BIM) is an information model applied in the whole life cycle management of buildings. It can be stored in BIM to realize refined and informational management of the construction industry. Geographic Information System (GIS) is a spatial information system that can collect, store, manage, calculate, analyze, display and describe data related to geographical distribution in the entire or part of the earth's surface space. The display and analysis of spatial information has the advantage of being fast and intuitive. [0003] As a major mode of transportation, highway plays a vital role in the development of social economy. There will be many diseases and problems in the operation of highways at all levels, such as the u...

Problems solved by technology

When determining the condition of the road surface, if BIM technology is used, because BIM technology has great advantages in displaying the details of individual objects, it can provide detailed attribute information of the road model, but due to the high requirements for hardware, it cannot Show large scenes with surrounding environment

However, if GIS technology is used, it can display and analyze the spatial information of roads in a large scene, but it does not have the function of displaying specific details of local objects.
