摘要： A geometric plane defined by a building-perimeter feature in an image capture by a mobile device is identified. The building-perimeter feature is co-located with an exterior wall of a building within which the mobile device is located. An orientation and/or location of the mobile device with respect to the geometric plane and an orientation of the mobile device with respect to a defined geographical direction are determined. A building model for the building and defining perimeter portions of the building (each perimeter portion corresponding to a respective exterior wall) is obtained or accessed. Based on the orientation and/or location of the mobile device with respect to the geometric plane, the orientation of the mobile device with respect to the defined geographical direction, and/or the building model, a particular perimeter portion of the building model that corresponds to the building-perimeter feature is identified and corresponding location information is determined.

摘要： Disclosed is an approach to improve data collection for a radio-based positioning system. The disclosed approach may involve processor(s) (e.g., of positioning server(s) and/or of a mobile device) obtaining radio data associated with the mobile device, where the radio data is collected while the mobile device is located within a particular vehicle during a time of commute. The processor(s) may determine a particular location of the particular vehicle representing where the particular vehicle is or was located during the time of commute. And the processor(s) may then use the particular location of the particular vehicle to geo-reference the radio data collected while the mobile device is located within the particular vehicle during the time of commute.

摘要： A processor obtains a plurality of instances of access point observation information. Each instance of access point observation information comprises (a) radio observation information corresponding to observation of one or more access points by a respective mobile device and (b) location information comprising an indication of a location of the respective mobile device when the respective mobile device observed the one or more access points. For one or more instances of access point observation information, based at least on the location information of the instance and a digital map that is accessible to the at least one processor, the process identifies a respective (TME) of the digital map that represents a portion of a traversable network where the mobile device was located when the mobile device observed the one or more access points; and associates at least a portion of the radio observation information with the respective TME.

摘要： The disclosure provides methods, apparatus, and products for updating a positioning map and a position estimate based on the detection of delivery events. An example method comprises obtaining a delivery address corresponding to a delivery to be made by an entity associated with a mobile device; obtaining sensor data captured by the mobile device; based on processing the sensor data, determining occurrence of one or more events indicating a moment in time that the delivery took place at the delivery address; obtaining (a) a position estimate for the mobile device substantially corresponding to the moment the delivery occurred and/or (b) delivery moment data captured by one or more sensors of the mobile device substantially at the moment the delivery took place; and updating a positioning map and/or the position estimate for the mobile device.

摘要： Disclosed is an approach for detecting that a state of an air-conditioning system in a building has changed and ultimately determining the air-conditioning system's operating pattern, which could help improve collection and/or use of crowdsourced data for an indoor positioning solution and thus lead to more accurate position estimates. According to the disclosed approach, processor(s) may receive sets of altitude data respectively from groups of mobile devices in the building, each set being associated with a respective time period, and could determine floor models of the building respectively based on the sets. Then, processor(s) could make a determination that at least one of the floor models is different from others, and could use this determination to detect that a state of the air-conditioning system has changed during particular time period(s), which are associated with set(s) of altitude data used to determine the at least one floor model.

摘要： A method, apparatus and computer readable storage medium are provided for determining a path of a mobile device in a public transportation building. In a method, a plurality of position data items are collected. Each position data item represents a respective position parameter captured by a mobile device that is indicative of a coarse position of the mobile device when the respective position parameter was captured by the mobile device. The method also includes determining, at least partially based on the position data items and public transportation data, an arrival area and/or a departure area of the public transportation building as start and end, respectively, of the path. The method further includes determining, at least partially based on building map data, a plurality of potential paths of the mobile device in the public transportation building starting at the arrival area and/or ending at the departure area.

摘要： A computing device obtains an instance of radio observation data and an associated circumstance parameter. The instance of radio observation data indicates an observed signal strength a radio node observed by a mobile device. The circumstance parameter indicates a characteristic of motion of the mobile device and/or a characteristic of the environment about the mobile device when the instance of radio observation data was captured. The computing device determines a context associated with the instance of radio observation data based at least in part on the circumstance parameter; determining a context-specific signal strength correction based at least in part on the context; generates a corrected signal strength of the radio node based on the observed signal strength and the signal strength correction; and generates and/or updates a radio map based at least in part on the corrected signal strength of the at least one radio node.

摘要： A method includes obtaining piece(s) of calendar information indicative of at least one appointment taking place in a space and extracting a set of space identifiers representing space(s) of the venue. The space identifier(s) for one or more spaces are extracted based on an indoor map of the venue. The method also includes determining or triggering determining whether at least a part of the set of space identifiers or one or more spaces of the set of space identifiers match(es) the at least one space as represented by the piece(s) of calendar information; and if a match is found: determining one or more reference location estimates. A respective reference location estimate is indicative of a location of the space that was determined to be a match. A corresponding apparatus, computer program product and system are also provided.

摘要： A method, apparatus and computer readable storage medium permit an updated radio map to be determined. In an iteration, the method obtains or holds available current radio map data representing a current radio map for a site and track data of a mobile device. The track data includes sensor data and radio signal observation data representing sets of radio signal observation results captured at different observation positions. The method estimates the observation positions on the track based on the current radio map data and the track data including the sensor data and the radio signal observation data and associates each estimated observation position with a respective set of radio signal observation results represented by the radio signal observation data to determine a sequence of radio fingerprints for the track. The method provides or uses the sequence of radio fingerprints for determining an updated radio map for the site.
