Abstract

Computer technology is widely developed and implemented. Many companies use unmanned aerial vehicles (UAVs) to obtain information about buildings and facilities for construction or renovation. The following methods can be used to provide data from UAVs: laser scanning or digital aerial photography. Each of them has its own advantages. The distinctive feature of laser scanning is the high speed of data acquisition and processing, as well as the ability to work at any time, regardless of the light. Digital aerial photography, in its turn, is characterised by high productivity and inexpensive equipment. Given the development of data acquisition and processing methods, the creation of digital copies of buildings and structures has recently become widespread. Today this process has become more accessible and convenient. This article deals with the acquisition of data from unmanned aerial vehicles. A digital twin is a digital copy of an object that is used to realistically represent a physical model. It can be a digital twin of a single object or a global model of processes affecting hundreds of thousands of people. Digital twin technology and BIM-technology are related to each other, but have a number of features that distinguish them from each other. The article compares information modelling and the technology of creating a digital twin of buildings. The aim of the paper is to identify and analyse the problems that can be encountered when creating a digital twin and to find their solutions.
