System and method for establishing virtual space model on the basis of wireless induction signal

Abstract

The invention provides a system and method for establishing a virtual space model on the basis of a wireless induction signal. By arranging wireless signal transmitting devices at a key position of abuilding surface, the wireless signal strength and an intersection angle of a signal source and a multi-channel signal receiving device are collected by the multi-channel signal receiving device connected with portable intelligent terminal equipment, and then the wireless signal transmitting devices are positioned to locate the building surface, a three-dimensional model of the whole building is established, and the simpleness and high efficiency are realized, a lot of time for surveying and drawing for designers can be saved, space model data obtained by the method is accurate and consistentwith actual spatial data, and the data is actual and has no errors; for each wall body, the three-dimensional model of the wall body can be simulated only by positioning at least four vertex angle positions, and positions of doors and windows can be simulated efficiently and conveniently; the modeling method is directly imaged on the portable mobile device, the operation is simple, no professionaldrawing knowledge is required, and the method is widely accepted.

Description

technical field [0001] The invention relates to the field of three-dimensional modeling, in particular to a system and method for constructing a virtual space model based on wireless induction signals. Background technique [0002] At present, in the field of architectural space measurement, in order to obtain the three-dimensional space model inside and outside the building, the method generally adopted is to first manually measure the length, width and thickness of the wall, and then make a floor plan, and then render the floor plan virtually. Create a 3D three-dimensional architectural space model map, or use VR software to simulate room type data. There are too many manual links in the above operations, and the follow-up processing workload is relatively large, and the efficiency is low. [0003] As a new research hotspot in today's information field, wireless sensor network integrates the cross-disciplines of various technologies such as sensing technology, microelectr...
