摘要：

Tn close-range applications, digital methods an increasingly used. Tn addition to the software and techniques which were adopted from aerial photogrammetry, new strategies for the restitution and presentation of digital data have been developed. The 'Digital Projector' is a strictly photogrammetric approach using raytracing techniques and off-the-shelf software to provide 3D models with complete texture. It works regardless of the shape of the object while allowing digital presentation ('photomodels') with numerous derivative results (e.g., orthoimages and animations). (C) 1999 Elsevier Science B.V.
