Approaches to the Generation of Three-Dimensional Building Models

The authors describe two approaches to the construction of three-dimensional models of wooden objects on the example of building No. 41, found in the excavation “Tatar Slobodka” in the village of Sviyazhsk in 2011–2014. The first approach is to photograph the assembled space in the building and continue its construction in the program Agisoft Photoscan. The model obtained in this way, has been called by the authors "monolithic". The second approach is based on the collection of structures on a single platform from individual models of wooden elements that make up its structure. Thus a "combined" model has been constructed by the authors. Two approaches was based on photogrammetry methods. In the course of the study, a comparison was made between the methods of obtaining "monolithic" and "composite" models, each of which has a number of advantages and disadvantages. "Monolithic" is characterized by high speed of the model and a small amount of memory. "Сombined" model allows you to compose the model of the building from the elements in the computer without its actual collection in space.
