Abstract

The present invention relates to a method for building in a single oblique photographic model in the cloud, comprising: generating an oblique photographic model; filtering point cloud data; establishing multiple point cloud data sets; preliminarily determining the identity of the object to which each point cloud data set belongs Type; perform secondary judgment on the point cloud data set; perform corresponding singulation on the point cloud data set; output map data to the web page; the invention directly singulates the building in the oblique photography model through the Internet cloud , which can effectively avoid the situation that there is no corresponding software in the host to perform individualization, resulting in the failure to generate a single model. At the same time, there are multiple preset floor areas and multiple preset height standard data groups in the cloud. According to Selecting the corresponding preset height standard for different floor areas can further determine the actual type of the object to which the point cloud data set belongs, effectively improving the singulation efficiency of the building in the oblique photographic model in the method of the present invention.

Description

technical field [0001] The invention relates to the technical field of oblique reality modeling, in particular to a method for building in a cloud-based single oblique photographic model. Background technique [0002] With the rapid development and maturity of oblique reality modeling technology, the realization of spatial information object management, query, analysis, statistics and other applications through 3D data has become an inevitable trend in the industry. Because of its fully automatic generation mechanism, the oblique photography real scene 3D modeling technology builds a continuous and integral TIN network structure, which determines that the obtained model results are "integrated" model results, and there is no category distinction for the attribute information of objects. , can not realize the separation and extraction of each type of ground objects or even each individual object, lack the ability to manage and analyze three-dimensional spatial information obj...
