Problems solved by technology

However, in the data preparation of land parcels and natural buildings, especially the latter, the unified registration of 3D real estate encounters common difficulties. Manual modeling, tens of thousands of natural buildings make the cost of data production high, which is unbearable in the field of unified real estate registration; if the building is automatically generated according to the vector base of the house, the lack of realism and aesthetics will be great

Abstract

The invention discloses a building three-dimensional modeling method and a building three-dimensional modeling device. The building three-dimensional modeling method comprises the steps of: generatingan oblique photographic model of a target building based on oblique photographic data, and generating a vector model of the target building based on vector data, wherein the vector model comprises afloor household model and a natural building external contour model; and carrying out fusion processing on the oblique photographic model and the vector model to generate a three-dimensional fusion model of the target building. The building three-dimensional modeling method and the building three-dimensional modeling device utilize the rapid modeling means such as generation of the oblique photographic and vector models, save the modeling cost, reserve the sense of reality of the models, maintain the strong correlation between the models and real estate business data, solve the difficulties such as modeling cost, efficiency, individual-floor and individual-household individualization, real estate business attribute data correlation of rapid modeling of a three-dimensional real estate floorhousehold natural building, realize the rapid production of a three-dimensional real estate floor household natural building model, improve the working efficiency and using experience degree of users.

Description

technical field [0001] The invention relates to the technical field of three-dimensional modeling, in particular to a method and device for three-dimensional modeling of buildings. Background technique [0002] The commonly used technologies for 3D modeling include oblique photogrammetry, laser point cloud, manual modeling, vector parametric modeling, and panoramic camera, etc., each has its own advantages in terms of modeling speed, cost, accuracy, geometric topology, etc. There are also problems. For example, oblique photographic modeling is fast and relatively low-cost, and is suitable for rapid modeling of large-area, unoccluded ground scenes. However, due to the loss of geometric topology information, there are difficulties in singulation and strong association with business attributes, resulting in an unsatisfactory impression of visualization for the sake of visualization, which affects the scope of application. The point cloud model is suitable for reverse modeling...
