摘要： An indoor area may be localized to provide end users with a mobile-accessible map to guide the end user in navigating the indoor area. A preliminary version of a map of the indoor area to be localized is processed to identify different navigable routes within the indoor area. A user may access the processed map and collect sensory data using the mobile device while moving along any of the navigable routes. The different sensory data that is collected at the same moment in time may be associated based on the location of the mobile device when the data is collected. The localized map is then generated with visual indications of the locations of the corresponding sensory data. The end user may then access the localized map on a mobile device to navigate the indoor area and to locate specific points of interest corresponding to the sensory data.

摘要： A system and method for determining the location of a mobile device is provided. Such a method includes receiving an interior map, determining a first location to be an absolute location of a mobile communication device, locating the absolute location at a first position on the interior map, relocating the mobile communication device to a second location, estimating the second location of the mobile communication device based on an output of one or more sensors and modifying, using a computer-based system, the estimated second location based on a comparison of the estimated second location to the interior map.

摘要： Aspects of the present disclosure provide systems and methods for generating models of a wireless network environment in an indoor space which may be used to predict an indoor location. The disclosure relates to collecting wireless network access point identifier information and power level observed at various locations are collected to generate various signal maps. The signal maps may be used to generate models of the indoor space. In one example, a voting model may use a probability distribution of a plurality of signal maps in order to identify a location with a highest probability of overlap with current signals received at a client device. Once a location has been identified, it may be used to assist with any number of navigational functions, such as providing turn by turn directions to another indoor location, for example, a conference room or exit, or simply providing information about the current location.

摘要： Methods and systems permit automatic matching of videos with images from dense image-based geographic information systems. In some embodiments, video data including image frames is accessed. The video data may be segmented to determine a representative image frame of a segment of the video data. Data representing information from the representative image frame may be automatically compared with data representing information from a plurality of image frames of an image-based geographic information data system. Such a comparison may, for example, involve a search for a best match between geometric features, histograms, color data, texture data, etc. of the compared images. Based on the automatic comparing, an association between the video and one or more images of the image-based geographic information data system may be generated. The association may represent a geographic correlation between selected images of the system and the video data.

摘要： Directions are provided to a location in an indoor space in response to receiving a request from a mobile device. First, a map of the indoor space is processed to identify navigable areas in the indoor space. A distance transform is then executed on the map as part of a process to generate a directed graph. The directed graph includes nodes that correspond to points in the indoor space and paths that correspond to routes between the nodes. Next, a navigation table is generated based on the directed graph to identify a shortest route from each node to at least one other node. In response to a request for directions to a location in the indoor space, the navigation table is accessed to identify a route to the requested location. The identified route is then provided to a mobile device such that an end user may navigate to the location.
