Shape integration of multi stereo images using surveyed points for an archaeological site

Abstract

Proposes a new method for reconstructing complete 3D shapes and colors of outdoor objects, especially of archaeological sites, as a reconstructed 3D image can be useful for archaeological research. The method integrates two kinds of data: (1) partial surfaces (inaccurate object surfaces with color information which are obtained by stereogrammetry, each of which has its local geometry fixed on the roughly calibrated stereo cameras), and (2) surveyed points (sampled points whose 3D coordinate values are represented with the world geometry and accurately measured by a sensor). The authors focused on fitting the partial surfaces to the surveyed points, and adopted adjustment processes which contained two feedback loops. The method is applied to an outdoor 3D measurement of the Kamaato archaeological site.
