Problems solved by technology

[0005] Another kind of individualized fine modeling is mainly manual modeling using related software. The 3D model of manual modeling is effective, but the modeling process is complicated, the structure is complicated, the production cycle is long, and it cannot adapt to the rapidly changing urban environment update. The production and mapping of textures is very troublesome, and the ground features and landforms are relatively virtual, and the fidelity is poor and there is a big contrast with the real world

Abstract

The invention discloses a local rapid updating method based on mobile phone image live-action refined modeling, which can ensure that mobile phone ground image acquisition and unmanned aerial vehicle oblique photography image acquisition are carried out at the same time, and images acquired by the two methods have no chromatic aberration. The updated specific building in the three-dimensional live-action model is consistent with the surrounding updated building in color and is beautiful. The data file format of the ground image shot by the mobile phone is consistent with the data file format of the image shot by the unmanned aerial vehicle in oblique photography, the collected data is image data, the model fusion problem of two model formats does not exist, and the refined updating of a specific building model in a large-area three-dimensional real scene model can be completed only by replacing related data files. Compared with the prior art, the method is quicker, and the efficiency of refined modeling updating work of specific buildings is greatly improved on the premise that the precision requirement and attractiveness of the model are guaranteed.

Description

technical field [0001] The invention relates to the technical field of refined modeling, in particular to a method for local rapid updating of refined modeling based on mobile phone images. Background technique [0002] With the continuous improvement of various measurement methods, the means of obtaining spatial data and the geographic information industry have developed rapidly. The process of urbanization is accelerating, and digital cities and smart cities are developing rapidly. The traditional two-dimensional digital map can no longer meet the relevant needs of various industries. Compared with traditional two-dimensional maps, three-dimensional data has many advantages such as more intuitive; more real; larger data volume; higher precision. [0003] Oblique photogrammetry technology is now the mainstream technology for large-scale 3D modeling. By carrying multiple sensors on the same flight platform, images are collected from different angles such as one vertical a...
