    摘要： Techniques and architecture are disclosed for mobile transport systems configured to determine vehicle positions within an area using light-based communication signals. The system includes a plurality of luminaires located in an area and configured to transmit luminaire position data recognizable by a sensor disposed on a vehicle. The sensor receives an image of a luminaire including a light-based communication signal encoded with luminaire position data. Luminaire position data can be combined with luminaire layout information to determine a known location of the luminaire. A vehicle position relative to the known luminaire location can be determined based on mathematical relationships. Vehicle orientation relative to the area can be determined based an asymmetric fiducial pattern or multiple known luminaire locations. The system can combine a vehicle position relative to a known luminaire location with vehicle orientation relative to the area to determine a vehicle position relative to the area.

    摘要： Techniques for determining an actual position of a portable device are disclosed. In an embodiment, a two-tier triangulation and wireless beacon-enabled luminaire detection approach is implemented. An estimated position of a device is determined using wireless (e.g., wireless beacon) triangulation based on a signal parameter of a signal received from a wireless access point. The field of view of the portable device may be used to estimate positions of luminaires proximate the portable device. The actual position of the luminaires may be determined from the estimated position by querying a database. A second triangulation may be performed using the known position of the luminaires to determine the position of the portable device with respect to the actual position of the luminaire.
