  • Publication number: 20230394746
    Abstract: Various implementations provide a 3D floor plan based on scanning multiple rooms. A combined, multi-room 3D floor plan may be generated from multiple 3D floor plans from distinct, non-contiguous room scans, e.g., a first scan that is distinct from a second scan. In some implementations, combining 3D floor plans utilizes a process that, during a second scan, re-localizes in the first room and then tracks the device as the device moves (e.g., as the user walks) to the second room to scan the second room. In other implementations, combining 3D floor plans is based on user input, e.g., positioning the multiple 3D floor plans relative to one another based at least in part on a user positioning graphical representations of the floor plans relative to one another on a user interface.

  • Publication number: 20230394765
    Abstract: Various implementations disclosed herein include devices, systems, and methods that provide a 3D room plan that combines 2D shapes representing elements of a room that are approximately planar (e.g., walls, wall openings, windows, doors, etc.) with 3D primitives representing non-planar elements (e.g., tables, chairs, appliances, etc.). A 3D room plan is a 3D representation of a room or other physical environment that generally identifies or otherwise represents 3D positions of one or more walls, floors, ceilings, other boundaries, other regions, windows, doors, openings, and 3D objects (e.g., objects having significant height, width, and depth in 3 dimensions) within the environment. For example, a 3D floor plan using 2D shapes to represent walls, windows, doors, etc. may be combined with 3D primitives such as 3D bounding boxes representing 3D objects to form a 3D room plan.
