An affordable automated 3D surface scanner: the case of Canaletto’s ‘The Grand Canal, Ascension Day’

Aure Calvet, Xavi

Abstract

We present an affordable and automated 3D scanner to record the structure and colour of planar surfaces of artworks. The system is based on the combination of photogrammetric and Reflectance Transformation Imaging (RTI) data and generates high-resolution digital reproductions. Seamless registration of RTI images to the photogrammetric mesh data produces a variety of 2D and 3D outputs for documentation and visualisation purposes. The design is developed for the recording of paintings of any size and in situ. We scanned an 18th century canvas painting by Venetian artist Canaletto to demonstrate initial results.
