Paper Abstract

The warped poplar panel and the technique developed by Leonardo to paint the Mona Lisa present a unique research and engineering challenge for the design of a complete optical 3D imaging system. This paper discusses the solution developed to precisely measure in 3D the world's most famous painting despite its highly contrasted paint surface and reflective varnish. The discussion focuses on the opto-mechanical design and the complete portable 3D imaging system used for this unique occasion. The challenges associated with obtaining 3D color images at a resolution of 0.05 mm and a depth precision of 0.01 mm are illustrated by exploring the virtual 3D model of the Mona Lisa.
