Method and system for rapid three-dimensional mapping

Abstract

The invention provides a method and system for rapid three-dimensional mapping. The method comprises the steps that a model base is established and a scene model serves as a basic unit for modeling in the model base; topographic data are collected, the topographic data are converted into geometric data, and a land parcel graph is established according to the geometric data; according to a current scene object, the scene model corresponding to the current scene object is looked up in the model base; the found scene module is added to the land parcel graph and a three-dimensional scene is established. According to the method, the scene model serves as the basic unit for modeling; in the process of modeling, the needed scene model is extracted from the model base established in advance, the modeling is simple in process, and establishment of the three-dimensional scene is rapidly achieved.

Description

Technical field [0001] The invention relates to the field of image technology, in particular to a method and system for rapid three-dimensional mapping. Background technique [0002] With the development of three-dimensional mapping technology, monotonous text data and two-dimensional symbolic representations no longer meet people's needs. The intuitive display of information through three-dimensional mapping technology is conducive to the analysis and processing of large amounts of information. . [0003] In the prior art, the three-dimensional drawing method uses geometric elements such as points, lines, and surfaces as the minimum editing units, and uses points, lines, and surfaces as the basic units for modeling. Use modular modeling and rendering methods to produce visualization products for different purposes, such as the Internet, computer games, multimedia, architectural design, interactive TV, education and training, simulation and product display, etc. Users can read, D...

Problems solved by technology

[0004] According to the above description, it can be seen that when users need to build a 3D scene, they need to model with points, lines, and surfaces as basic units. When changing the object model in the scene, they need to modify and compile the information at the bottom layer to achieve , the modeling process is complex
