CONFIGURATION METHOD FOR THE DISPLAY OF A BUILDING INFORMATION MODEL

WIPO Patent Application WO/2022/207687

A3

Certain examples described herein present a method of configuring a headset for display of a building information model (BUM) at a construction site. In one example, the method includes: determining a pose of the headset using a positioning system; obtaining an image of a two-dimensional marker positioned within the construction site; determining a BIM-to-camera transformation between an origin of a coordinate system used by the building information model and an origin of the coordinate system of the camera based on a location of the two-dimensional marker within the image; determining a camera-to-positioning transformation between the origin of the coordinate system used by the camera and an origin of a coordinate system used by the positioning system; and determining a BIM-to-positioning transformation.
