“…A point cloud can be divided in different entities such as the main walls, the columns, the capitals and altars, separating the general geometry of the structure from the architectural details. For instance, the main walls need low resolution while the columns, the capitals and the altar need a large number of triangles [20]. The result should be a light numerical model with a good number of details (semi-automatic process).…”

Despite the technologies are now part of the archaeological discipline, they must not divert attention from archaeological issues and should be aimed at solving different historical and methodological questions, such the phases of a monument or innovative representation methods. The paper focuses the attention mainly on the use of range-data and image-based systems applied to the archaeological heritage, in order to highlight differences between the techniques and the related errors. Some considerations are necessary in order to find possible solutions for improving the quality and the accuracy of a survey project, considering the recent and innovative techniques adopted in archaeology. At the same time the authors provided, where possible, some solutions and suggestions for reducing the errors and checking the general quality of the work. Different experimentations have been made on some case studies that show how to manage technologies trying to reduce as much as possible the errors in the different phases of the survey pipeline. A specific part has been dedicated to the photogrammetric process from drones compared to traditional acquisitions, usually performed with aluminium poles, and the common errors in the representation of the archaeological excavations.

“…Usually the image projection is performed directly on the point cloud in the 3D model space or visualizing the ecquirectangular projection of the scan with the reflectance information associated (planar representation at very high resolution; Carpiceci et al, 2018). In the model space the recognition of the points is very difficult to select, considering the all-round view of the point clouds and the impossibility to zoom the model for a detailed view, conditioned from the resolution and the distance between the points.…”

ABSTRACT:The development of the survey techniques for architecture and archaeology requires a general review in the methods used for the representation of numerical data. The possibilities offered by data processing allow to find new paths for studying issues connected to the drawing discipline. The research project aimed at experimenting different approaches for the representation of the rupestrian architecture and the texture mapping process. The nature of the rupestrian architecture does not allow a traditional representation of sections and projections of edges and outlines. The paper presents a method, the Equidistant Multiple Sections (EMS), inspired by cartography and based on the use of isohipses generated from different geometric plane. A specific paragraph is dedicated to the texture mapping process for unstructured surface models. One of the main difficulty in the image projection consists in the recognition of homologous points between image and point cloud, above all in the areas with most deformations. With the aid of the "virtual scan" tool a different procedure was developed for improving the correspondences of the image. The result show a sensible improvement of the entire process above all for the architectural vaults. A detailed study concerned the unfolding of the straight line surfaces; the barrel vault of the analyzed chapel has been unfolded for observing the paintings in the real shapes out of the morphological context.
