Abstract

The invention relates to a method for building in a cloud monomer oblique photography model. The method comprises the following steps: generating an oblique photography model; filtering the point cloud data; establishing a plurality of point cloud data sets; preliminarily judging the type of an object to which each point cloud data set belongs; performing secondary judgment on the point cloud data set; performing corresponding monomerization on the point cloud data set; outputting the map data to a webpage end. According to the invention, the building in the oblique photography model is directly monomerized through the internet cloud, and the situation that the monomerized model cannot be generated due to the fact that no corresponding software exists in the host for monomerizing can be effectively avoided. Meanwhile, a plurality of preset floor areas and a plurality of preset height standard data sets are arranged in the cloud; by selecting corresponding preset height standards according to different occupied areas, the actual type of the object to which the point cloud data set belongs can be further judged, and the monomer efficiency of the method for the building in the oblique photography model is effectively improved.

Description

technical field [0001] The invention relates to the technical field of oblique real-scene modeling, in particular to a method for building in a single oblique photographic model in the cloud. Background technique [0002] With the rapid development and maturity of oblique reality modeling technology, it has become an inevitable trend in the industry to realize spatial information object management, query, analysis, statistics and other applications through 3D data. Oblique photographic real-scene 3D modeling technology, because its automatic generation mechanism is to build a continuous and overall TIN network structure, determines that the obtained model results are "integrated" model results, and there is no category distinction for the attribute information of ground objects , it is impossible to realize the separation and extraction of each type of ground object or even each individual object, and it lacks the object management and analysis ability of three-dimensional s...
