Abstract

Motivated by the need for a fast, accurate, and high-resolution approach to documenting heritage and archaeological objects before they are removed or destroyed, the goal of this paper is to develop and demonstrate advanced image-based techniques to capture the fine 3D geometric details of such objects. The size of the object may be large and of any arbitrary shape which presents a challenge to all existing 3D techniques. Although range sensors can directly acquire high resolution 3D points, they can be costly and impractical to set up and move around archaeological sites. Alternatively, image-based techniques acquire data from inexpensive portable digital cameras. We present a sequential multi-stage procedure for 3D data capture from images designed to model fine geometric details. Test results demonstrate the utility and flexibility of the technique and prove that it creates highly detailed models in a reliable manner for many different types of surface detail.
