Paper Abstract

A prototype of a system to measure and represent small objects is presented. It consists of two CCD cameras, a motorised rotation plate and a projector, all controlled by a microcomputer. The measurement of objects is performed by automatic determination of heights along curves. Each curve is obtained by localising a point projected on the object which is rotated around itself. The rigorous camera calibration assures a precision of the measured coordinates of the order of 0.5 pixel in object scale. After completion of the digitisation, software for digital cartography is used to represent the object and to determine further quantities such as distances, surfaces and diameters. An example showing the use of the system is given.
