ABSTRACT

Traditionally, Cultural Heritage Assets are valuable artifacts requiring special - time consuming and costly - manual preservation procedures and always subject to accidentally or intentional damage. The paper main objective are: Using low-cost & real time or late -time (client-server) methodologies at all digital documentation phase, to make CHA accessible to all interested in people by supporting virtual mobility without CHA preservation cost and using CHA digital copies and exact 3d replicasto unlock the potential of reusing CHA for creative understanding, collaborative learning and critical thinking. From these two objectives the necessity for accurate and rapid 3D modelling is obvious. Perspective projection theory and geospatial ICT provide the means for lowcost accurate 3D modelling resulting in CHA digital documentation in the fields of cultural heritage, architecture&archaeology. Even more the low-cost 3D modelling offer great functionalities for ortho-photography&DEM, 3D model reconstruction, quality textured building reconstruction, dense cloud classification &DTM generation, and area and volume accurate measurements.

Keywords: digital documentation, 3D modelling, area &volume measurements
