摘要: Anchor points associated with point of sale information may be ordered by segmenting a trajectory derived from sensor data defined by adjacent turns to generate candidate links for each segment from which possible paths for the trajectory are derived. Each derived possible path may be scored with a multi-objective function using a global optimization algorithm to select a solution path from the derived possible paths that may be used to order a plurality of anchor points.

摘要: The navigation solution of a portable device may be enhanced using map information. Sensor data for the portable device may be used to derive navigation solutions at a plurality of epochs over a first period of time. Position information for the device may be estimated at a time subsequent to the first period of time using the navigation solutions. Map information for an area encompassing a current location of the portable device may also be obtained. Multiple hypotheses regarding possible positions of the portable device may be generated using the estimated position information and the map information. By managing and processing the hypotheses, estimated position information for at least one epoch during the first period of time may be updated. An enhanced navigation solution for the at least one epoch may be provided using the updated estimated position information.
