3D building modeling method and system

Abstract

The invention discloses a 3D building modeling method and system. The 3D building modeling method comprises the steps that building images are acquired and an orientation of a main building is determined among obtained building images; and after the building images are acquired, the method sequentially comprises the steps that the high-resolution images undergo corresponding processing, an area required to be modeled is interpreted, a correlation model is established for different images of a plurality of the same buildings and a determined 3D model of the building is printed. According the method and system, data estimation in different periods can be carried out according to a one-time aerial photography image, so that multiple-time aerial photography is unnecessary; an output end is arranged for printing and displaying the modeling; due to the timeliness of a high-resolution number-two image, the high-resolution number-two image can be downloaded and updated on a website in real time, an image of the area to be studied is inverted to obtain a recent image, the processed high-resolution number-two image is inserted into the previous pre-synthesized image, and the previous processed high-resolution number-two image is replaced, so that a recent research and synthesis modeling model of a to-be-researched building is formed.

Description

technical field [0001] The invention relates to the technical field of building modeling, in particular to a 3D building modeling method and system. Background technique [0002] The architectural and environmental art model is between the plane drawing and the actual three-dimensional space. It organically links the two together. It is a three-dimensional three-dimensional model. The architectural model is helpful for the deliberation of design creation and can intuitively reflect the design intention. , to make up for the limitations of drawings in performance (see architectural drawing). It is not only a part of the designer's design process, but also a form of design. It is widely used in urban construction, real estate development, commercial housing sales, design bidding and investment cooperation. Architectural model is an architectural term, which expresses the spatial effect of the design scheme with its unique image. [0003] With the development of society, the ...

Problems solved by technology

[0005] In view of the above problems, the present invention provides a 3D building modeling method and system, which can perform data estimation in different periods based on one aerial image, which eliminates the necessity of multiple aerial shots, and sets an output terminal for printing display. It solves the communication bottleneck between the current research plan and objects, and realizes the finished product; it can effectively solve the problems in the background technology
