摘要

Process and apparatus for digitalization of the surface of a three-dimensional object. Said apparatus is of the type which comprises a laser lighting system and a video device. According to the invention the video device is suited to filming the object from two different points of view (C1, C2), namely a top shot and low-angle shot, and the lighting system comprises two sources (L1, L2) laterally offset in relation to the view points of the video device, and located at different heights in order to illuminate the object, one for top shots and the other for low-angle shots, in order to produce two luminous tracks on said object. The video signals provided by the video device are separated in order to distinguish the information relating to each of the two tracks. In this way it is possible to read in a complete manner, and without any masked or non-apparent part, the co-ordinates of the surface of an object which has pronounced relief or receding parts, such as a human head or bust.
