Abstract
In some embodiments, a method comprises receiving a plurality of digital images depicting an indoor scene of a room and captured using a capture device, and trajectory data of a trajectory that the capture device followed as the capture device was capturing the images; wherein the images and the trajectory data satisfy quality checks, including a closed loop check that requires that first images, of the plurality of digital images, and last images, of the plurality of digital images, overlap; determining a point cloud by preprocessing the digital images and the trajectory data to satisfy optimization constraints, and by identifying and labelling a plurality of feature points in data obtained by preprocessing the digital images and the trajectory data; based on the point cloud and the trajectory data, generating room geometry for the room and a 3D model of the room; and displaying a graphical representation of the 3D model.
