Head-mounted sensor system
Systems and method of mapping spaces include a head-mounted sensor array. The array includes sensors configured to both measure distances within spaces and capture images of the spaces. This data may be used to generate continuously navigable virtual simulations of the spaces. Mapping of the spaces may include movable objects such as doors, transparent objects such as windows, and transitions between floors.
