Integrated digitization method for cultural heritage objects

Abstract

Digitization of cultural heritage objects recently becomes very promising tool for storing information about precious artifacts. This work shows an integrated, multimodal measurement method for digitization of cultural heritage objects with the example of representative metal figurine. We propose an optical measurement system which uses structure light projection, multispectral color acquisition and Bi-Directional Reflectance Distribution Function (BRDF) estimation. Accordingly an implementation of data processing path is explained with illustration of its main steps and a final result. Full Text: PDF References J. Portal, Q.
