Abstract
The positioning/navigation solution of a portable device may be enhanced by obtaining motion sensor data, estimating a trajectory for the portable device from the motion sensor data, obtaining map information for an environment encompassing locations of the portable device, representing the estimated trajectory using a set of connected vectors and performing global shape matching for the set of connected vectors as an aggregate whole from start to end of the trajectory to the map information as a global optimization problem to derive a solution path.
