Abstract : A robust and general local search matching algorithm is used match fragmentary horizon lines. A horizon line model is extracted from a rendered terrain map and is then matched to features extracted from CCD imagery. Such matching is one means of automating vehicle orientation correction: a problem of practical significance for the UGV program. Currently, final orientation correction relating vehicle co-ordinates to terrain map coordinates must be performed manually. Results are presented for actual terrain and image data collected at the UGV Demo C test site.
