LOCATION ESTIMATION METHOD AND SYSTEM

摘要

A method of estimating the geographical location of an object from location information reported by one or more mobile devices having location determining means comprises collecting location data from the one or more mobile devices, preparing the data by selecting features of the data, training an estimator by inputting selected features of the data, and applying the estimator to a map grid to estimate the location of the object. During training of the estimator a kernel machine operates on histograms of distances that are computed with respect to a considered location and the user reports nearby. During application of the estimator, if the estimator assigns a score above a certain threshold a location is marked as the true location of the object. In case multiple locations are predicted, a subsequent clustering merges multiple predictions into one by using the weighted mean.

1. A method of estimating the location of an object within a geographical area based upon potential object location data reported by a plurality of mobile devices having location determining means, the method comprising:
collecting potential object location data from the plurality of mobile devices, dividing the geographical area into a plurality of regions, and for at least some of the regions: determining information indicative of the distance between a point associated with a region and the potential object location reported by at least some of the mobile devices, and applying an estimator model to assign a score to the point indicative of a probability that the point corresponds to an actual object, and estimating the location of the object based upon the scores assigned to the points.
