ABSTRACT
Several attempts and case studies had been conducted to document the cultural heritage using the 3D Laser scanner in the last few years. Now, it is possible to furnish a virtual model of an object from the pointcloud and to complete the direct measurements, just like if the user were physically present on the site. While the main users of this method are technical people (not archaeologist), the results of these studies could not be easily understood and clearly appreciated from a majority of the people involved in the process of documentation for the archaeological sites and monuments. By reviewing the latest articles and case studies of 3D laser scanner in heritage documentation, we can establish now, some general rules and recommendations, mainly for the non technical users involved in the process of this new documentation method and according to their actual needs. This paper attempts to present and evaluate the recently 3D laser scanner achievements and results in heritage documentation to create a dialogue between the specialized technician and non technician users, in order to decrease the gap and to build a bridge between them, taking into consideration the following factors: 1-Kind and type of the structure.2- Material and texture.3-Scale of the structure 4- Acquisition time in the field and the number of the required scan positions. 5- Data post processing time in the lab. 6- Accuracy and precision. 7- Benefit ratio and cost.
