Automated Track Projection Bias Removal Using Frechet Distance and Road Networks

摘要

A system and method for projecting target tracks produced by a remote tracker onto a surface of the Earth to obtain projected tracks is provided. Projection bias in a projected track from the remote tracker projected onto a planar map is removed by computing a discrete Frechet distance from a polygonal curve associated with a track derived from the remote tracker to a corresponding polygonal curve on the planar map. A correspondence between the projected track and a track on the planar map is automatically established. A projection bias is removed based on the correspondence.
