A Study on Extension of Contour Extraction Method to Support Remains Mapping

Abstract

A contour tracking method suitable for 3D natural geometry has been proposed to support the creation of remains maps. In this method, a set of partial points corresponding to an edge region is extracted from an input point set, an arbitrary starting point is set, and a growth vector is obtained considering the tracking direction and variation with respect to the local region, and contour lines are sequentially tracked. In the previous study, the ratio of tracking direction to local variation was fixed at 1:1, but in this paper, this ratio is varied and the length of the tracking line segment corresponding to the local region is adjusted in two steps to attempt more flexible tracking. Experiments on actual archaeological data was conducted to verify how the tracking results change.
