Abstract

The invention discloses a method and device for constructing a plane graph based on a UWB technology, and relates to the technical field of computers. A specific embodiment of the method comprises thesteps of obtaining device information and coordinate information of a UWB positioning device installed in a target building; Generating a sketch of the target building based on a starting sequence principle and / or a distance proximity principle according to the equipment information and the coordinate information; And optimizing the sketch by using the historical map corresponding to the target building to generate a planar graph of the target building. According to the implementation mode, the planar graph can be rapidly constructed based on the UWB technology, manual measurement errors areavoided, the measurement cost is reduced, and the user experience is improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a method and device for constructing a plan based on UWB technology. Background technique [0002] The building plan is the basic sample of the building construction drawing. It is a horizontal projection of the part below the cutting plane after imagining that the house is cut along the door and window openings with a horizontal cutting plane. The building plan can reflect the plane shape of the house, Size and layout, so building plans are of great significance for the construction and decoration of buildings. [0003] At present, there are mainly the following two methods to construct building plans: 1. Measure the distance of buildings by artificial dimensions, and then use CAD (that is, Computer Aided Design, which refers to the use of computers and graphics equipment to help designers carry out design work), etc. Professional drawing software is completed after a...
