Abstract
A method performs wireless localization data acquisition and calibration using a visual 3D model. The method includes: receiving image data and transmitter measurement data from a device; localizing the image data in the visual 3D model to determine a device location in a physical space; and using the device location and the transmitter measurement data to perform at least one of: determining transmitter fingerprint localization data and storing the transmitter fingerprint localization data in a fingerprint database; or calibrating a radio frequency (RF) propagation model for proximity estimation.
Claims15
A method for wireless localization data acquisition and calibration, the method comprising:
- receiving image data and transmitter measurement data from a device;
- automatically obtaining device location data by localizing the image data in a pre-constructed visual 3D model of a physical space to determine an estimation of a location of the device in the physical space;
- and
- using the device location data and the transmitter measurement data to perform:
- automatically determining transmitter fingerprint localization data by associating the device location data with the transmitter measurement data and storing the transmitter fingerprint localization data in a fingerprint database;
- and
- automatically calibrating a radio frequency (RF) propagation model for proximity estimation based on the device location data and the transmitter measurement data.
A system comprising a processor and a memory, the memory comprising processor executable instructions that, when executed by the processor, cause the processor to perform the following operations for wireless localization data acquisition and calibration:
- receive image data and transmitter measurement data from a device;
- automatically obtain device location data by localizing the image data in a pre-constructed visual 3D model of a physical space to determine an estimation of a location of the device in the physical space;
