Example Embodiment

[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0025] figure 1 The implementation process of the indoor 3D modeling method provided by the embodiment of the present invention is shown, and the details are as follows:

[0026] In S101, the drone positioning points are collected, and a local three-dimensional map is constructed according to the drone positioning points.

[0027] After the drone is started, from the initial position to the end of the modeling process, it always needs to collect its own positioning points, through these positioning points, from point to line, from line to surface, from surface to body can be sketched A three-dim...

Abstract

The invention is suitable for the field of virtual reality, and particularly relates to an indoor three-dimensional modeling method and device. The method comprises the following steps that: collecting an unmanned aerial vehicle locating point, and constructing a local three-dimensional map according to the unmanned aerial vehicle locating point; shooting an indoor image, and generating a partially visible three-dimensional model according to the indoor image; according to the partially visible three-dimensional model, calculating an integral three-dimensional model through pattern classification; according to the integral three-dimensional model and the local three-dimensional map, calculating an action path; driving the unmanned aerial vehicle to move automatically according to the action path, and calculating the three-dimensional model of a next region. In the embodiment of the invention, through a way of the automatic movement of the unmanned aerial vehicle and automatic surveying and mapping as well as modeling, users can more quickly carry out three-dimensional model reconstruction on a great quantity of buildings. In addition, manual surveying and mapping as well as modeling can be avoided so as to save human cost and improve the convenience of three-dimensional modeling.

Description

technical field [0001] The invention belongs to the field of virtual reality, and in particular relates to an indoor three-dimensional modeling method and device. Background technique [0002] Indoor 3D modeling technology has been widely used in architecture, civil engineering, tourism, digital maps and other fields, which can greatly improve the efficiency of people's understanding of indoor space. For example, in the field of real estate, compared with a few flat photos or structural drawings, a complete 3D simulation model can allow customers to understand the overall structure and every detail of the house more realistically, improving the efficiency and satisfaction of customers in buying houses. [0003] However, traditional indoor 3D modeling often requires relevant professionals to use expensive special customized equipment to take a large number of photographs and measurements of the indoor space, and requires manual assistance to complete, which is not only ineffi...
