| 摘要 |
The present invention relates to a videogrammetric process and device, that is to say a process and device for acquisition of numerical data relating to the coordinates of the various points of the surface of a three-dimensional object. This device is characterised in that it comprises a plurality of pairs of laser emitters (1-4; 1a-4a) producing respectively laser beams (f1-f4), these laser emitters being distributed by pairs of emitters producing pairs of coplanar beams projected onto the surface of an object (5) to be analysed, a plurality of video cameras (A,B C,D) directed towards the object (5) and means (7, 9, 11) for causing a relative displacement between the object (5) and all the pairs of laser emitters (1-4; 1a-4a). <IMAGE>
