Use of 3D terrestrial scanning (TLS) technology in the field of hydrotechnics [articol]

Abstract

The purpose of this paper is to present the advantages of using terrestrial laser scanning technology (TLS) as a method of creating a 3D database and to create a 3D documentation for the Coșteiu Hydrotechnical Node. This ultra-modern technology is an innovation that has the advantage of acquiring a large volume of data in a short time. This technology together with UAV equipment has the advantage of obtaining a digital terrain model. Creating 3D models of heritage, archaeological objects and sites in their current state requires specialized equipment, knowledge, and has a strong methodology, capable of capturing and digitally models the geometric details and fine appearance of these sites. Digital recording, documentation and preservation are required because our heritage (natural, cultural or mixed) suffers because of different anthropic and/or natural actions (natural disasters, climate change and let’s not forget about human negligence). Currently, 3D data represents a critical component for the permanent registration of the forms of important objects and sites, so that, at least in digital form, they can be transmitted to future generations. This has generated a large number of projects over the last decade, mainly led by research groups that have made very good quality models and complete digital models.
