摘要： A method of processing probe trace data to determine a measure of correlation of a probe trace with other probe traces comprises obtaining a map that associates a parameter space with a plurality of pixels, wherein at least one correlation value is assigned to each of the plurality of pixels, and determining a correlation score for a probe trace by mapping the probe trace to at least one pixel of the map and determining the correlation score for the probe trace from at least one correlation value of the at least one pixel to which the probe trace is mapped.

摘要： At least one example embodiment discloses a method for correcting location measurements for a navigable feature. The method includes selecting a first mean probe path representative of the navigable feature, first determining a 10 curvature of the first mean probe path, second determining a correction value to a corresponding location measurement based on a corresponding curvature of the first mean probe path, offset from the first mean probe path and speed, and third determining a first probe path based on the corrected location measurements.

摘要： Disclosed is a method for determining mean probe trace representations is disclosed. The method includes collecting probe traces consisting of sequential location measurements along navigable features including roads, and pedestrian ways. The method further includes sorting and clustering the probe traces based on the navigable features and sorting and clustering the probe traces into time sliced clusters based on a time period associated with acquisition of the probe traces. The method also includes determining a mean probe trace representation of the navigable features based on the time sliced clusters.

摘要： The invention provides a method of resolving a location in a second digital map from an ordered list of location reference points determined from a first digital map. The method involves identifying candidate lines and nodes in the second digital map, and using curvature, height and gradient information associated with the location reference points to identify the most likely candidate nodes or lines in the second digital map corresponding to the nodes represented by the location reference points and to lines emanating from or incident at the node in the first digital map. The method involves carrying out a route search between the most likely identified candidate node or line identified for one location reference point, and the corresponding node or line associated with the next reference point in the list, and repeating this step for consecutive pairs of reference points until the final location reference point is reached.
