US 11,443,483 B2 · Validating and updating building models with path data

Abstract

Systems, methods and instructions for creating building models of physical structures is disclosed. The building model may be a collection of floors defined by outlines containing regions that may be offset relative to a main region, and a collection of connectors. Connectors may have connection points for tracking, routing and sizing. Connectors may indicate elevation changes through georeferenced structural features. Signal elements may also be features that provide corrections when tracking. Feature descriptors are data that describes the structural configuration and signal elements enabling them to be matched to previously collected data in a database. User interface elements assist a user of a tracking device in collecting floor information, structural features and signal features and validating certain collected information based on previously known information. The height of floors may also be inferred based on sensor data from the tracking device.

Dependent claims

A computer-implemented method for validating and updating a building model, comprising:

localizing a position of a mapping device relative to a building structure, the mapping device being carried or worn by a user;
generating path data as the mapping device traverses the building structure;
based on the path data, identifying a plurality of connectors, each connector comprising a plurality of connection points associated with an elevation, the plurality of connectors being configured to track the mapping device and generate a routing graph for routing the mapping device through the building structure;
displaying, at a user interface, a portion of a building model corresponding to the localized position and the path data, wherein the building model comprises one or more previously mapped structural features and connectors;
adding at least one connector to the displayed portion of the building model;
receiving user generated inputs from the mapping device including a validation of at least one of:
the added connector and a structural feature in the building model;
and
updating the displayed building model based on the user generated inputs.
