Особливості реставрації великогабаритних ліплених посудин (досвід використання 3D-моделювання в реставрації)

Abstract

Подано інформацію про застосування методів фотограмметрії, зокрема 3D-моделювання, підчас реставрації ліпленого глиняного посуду. Поетапно розглянуто процес створення тривимірноїмоделі та її практичне використання під час реставраційних робіт.
 Сonservation of archaeological handmade ware, especially of the large size, has certain featuresand difficulties due to firing at low temperatures and the composition of the molding mass (the clay wascoarse with large inclusions).Such vessels usually come to our time in a worse condition than pottery, mostly in a form ofa collapses broken into many fragments, with a fragile surface, so they require a special approach to thechoice of methods, techniques and materials used for their restoration. In such cases the main task forthe conservator is to find such methods of working with handmade vessels, which on the one hand wouldbe completely safe, on the other – would provide the comprehensive study, restoration and preservationof broken archaeological ceramics.It should be noted that with the development of digital technologies in archaeology and restoration,the methods of photogrammetry used in non-invasive research of archaeological sites have spread.The article deals with the application of photogrammetry methods, in particular 3-d modeling duringrestoration work with handmade ware of a large sizes. We try to describe in detail the way of creatinga three-dimensional model at the stage of photo-fixation of the archaeological vessel before the beginningof restoration measures using as the example the handmade large pot (korchaga) of Sabatyn culture ofthe Late Bronze Age.In our case, a three-dimensional model of the exhibit was created to simplify the selection of fragmentsfor gluing (almost similar in shape and size) before the dismantling of a partially glued exhibit of 147fragments. Prior to photography, all fragments of the vessel were marked with paper stickers.Agisoft Photoscan v1.4.4 software was used for 3D reconstruction of the object.
