Abstract

This paper presents a simple and low-cost range finding system based on the absorption of light by a dispersive medium. The object to be digitized is immersed in a colored liquid and the 3-D data is obtained by processing a pair of greylevel images taken at different wavelengths. Calibration, acquisition, visualization and manipulation of the 3-D data are implemented through menus and graphic windows on a SUN-3 workstation.
