摘要： A method and system for detecting an indoor threshold transition in a positioning state. The method may be executable using one or more processors and comprises, upon detecting a pattern of magnetic anomaly characteristics associated with a sequence of position changes of the mobile device, extracting the pattern, comparing the extracted pattern with a stored magnetic signature associated with the indoor threshold, and based on the comparing, inferring that the mobile device is one of transitioning in position and has transitioned in position across the indoor threshold.

摘要： A method and system localizing a mobile device along a pedestrian route traversed in an indoor area, the mobile device including a processor and a memory. The method executed in the processor and comprises localizing the mobile device to an estimated first position within the indoor area based on accessing, from a first memory tier of the memory, a first portion fingerprint data that includes fingerprint data of a first subset area of the indoor area, the first subset area at least partly surrounding the estimated first position, detecting a traversal of the mobile device along the route to an estimated second position within the indoor area, and when a difference between the estimated first and second positions exceeds a threshold distance, replacing the first portion fingerprint data of the first memory tier upon pre-fetching a second portion fingerprint data, the second portion fingerprint data including fingerprint data of a second subset area of the indoor area, the second subset area at least partly surrounding the estimated second position.

摘要： Methods and Systems of adjusting a radio frequency (RF) broadcast signal power level in a crowd-sourced mobile device localization system in a pedestrian area are described. In an example, a first mobile device and a second mobile device may be localized to establish a first estimated position a second estimated position, respectively. The localizing may be based on fingerprint data of the pedestrian area, wherein a localization data packet including the first estimated position broadcasted by the first mobile device at a first broadcast power level and another localization data packet including the second estimated position broadcasted by the second broadcast device at a second broadcast power level may be received. Based on a degree of accuracy of the first estimated position and/or the second estimated position, an input may be provided to increase and/or lower at least one of the first broadcast power level and the second broadcast power level, wherein broadcast power levels mobile devices are increased and lowered based on a power level budget for the crowd-sourced localization system.

摘要： A method and system for localizing a mobile device includes deriving and using a spatial derivative magnetic signature or fingerprint. The method, executed in a processor of the mobile device, comprises monitoring mobile device magnetic data along a route being traversed, deriving, from the mobile device magnetic data, a mobile device spatial derivative magnetic fingerprint along the route, accessing a repository of spatial derivative magnetic fingerprint data having associated respective positions along the route, and localizing the mobile device based at least partly on matching the mobile device spatial derivative magnetic fingerprint with the spatial derivative magnetic fingerprint data of the repository.

摘要： A method and system for deploying a calibrated positioning map of an area. The method, executed in a processor of a server computing device, comprises generating, using the processor, a distribution of positioning data points based at least in part on a first set of fingerprint data, the positioning data points calibrated in accordance with respective positions within the area, receiving, at the memory, a second set of fingerprint data, processing, using the processor, the second set of fingerprint data and the positioning data points to generate an updated distribution of positioning data points, and when the updated distribution exceeds a threshold density of positioning data points, deploying the updated distribution as the positioning map of the area.
