For the youngest visitors of the 53rd STROIKO exhibition, the University of Ruse has planned to hold a children's workshop, in which the possibilities of applied block programming will be shown in a language accessible to children.
A team from the Department of Telecommunications at the University of Ruse "Angel Kanchev" will take part in the 53rd exhibition STROIKO EXPO autumn 2020, which this year is held under the motto HIGH TECH HOME AND CITY. On October 22, during the seminar "STROIKO EXPO: DIGITAL SOLUTIONS FOR MODERN LIFESTYLE", which is part of the accompanying program of the exhibition, professors from the University of Ruse will present a report on "Modern areas of application of 3D technologies without devices. and artificial intelligence. " The presentation focuses on the research activities of the RU team in recent years and includes various areas of application of unmanned aerial vehicles, 3D digitalization and visualization of objects, as well as the use of additive technologies. During the presentation, various possibilities for application of unmanned aerial vehicles (UAVs) will be presented - in construction, geodesy, architecture, archeology, mechanical engineering, agriculture and others.
During the event, the two-stage system for early fire detection, designed and created at the University of Ruse "Angel Kanchev", which uses artificial intelligence, neural networks and computer vision in combination with unmanned aerial vehicles with fixed and rotary wing, will be presented. The development is to receive a patent and was made within the project "Forest Monitoring System for Early Detection and Assessment of Fires in the Balkans-Mediterranean Region" (SFEDA).
Angel Kanchev University of Ruse has more than ten different types and functionality of unmanned aerial vehicles. Some of them include educational drones such as DJI Tello, aerial photo and video capture drones such as DJI Inspire, DJI S1000 + and Yuneec Typhoon H Plus, as well as industrial drones such as DJI Matrice M210RTK and DJI Mavic 2 Enterprise Dual. Since 2019, Angel Kanchev University of Ruse also has ALTi Transition F - a vertical take-off unmanned aerial vehicle with a fixed wing, which has a flight time of over 8 hours and a total range of 100 km.
The team of the University of Ruse is a national leader in the application of modern ICT technologies for preservation and promotion of cultural and historical heritage, through an attractive approach, with the development of flexible, multifunctional platforms for WEB, Android and IOS-based access to digitized content and information. Within the realized projects the team has the best available equipment for creation of terrestrial and aerial video and photo content with Ultra HD 4K resolution, laser 3D scanners with texture registration, powerful servers with licensed software for rendering and creation of three-dimensional content, photo and video realistic visualizations for integration into augmented and virtual reality (AR&VR) applications.
In recent years, the team has focused its efforts on creating methods and systems for attractive visualization of three-dimensional objects to promote cultural and historical heritage in public places. As a result of the activity, methods have been developed for creating content and projecting in holographic displays, which have the ability to visualize three-dimensional objects.
The integration of these systems in open public spaces (squares, foyers of public administrative buildings, stations, airports, libraries, schools, universities, etc.) are a successful way to promote cultural and historical heritage and promote historical, cultural and spiritual tourism. Since 2013, the digitalization team of the University of Ruse has been actively involved in the digitalization of cultural and historical heritage. In the framework of several international projects, more than 400 artifacts have been scanned and digitized, which are stored in 12 museums in the cross-border region between Romania and Bulgaria.
Over the years, serious experience has been gained, which is shared with all stakeholders in the framework of organized annual events and trainings for digitalization. 3D technology has revolutionized many industries and found application in a range of fields, from medicine to education. They are dynamic and rapidly evolving methods for transforming real objects into digital information.

In the process of digitalization, the team uses high-tech 3D scanners that have extremely high precision. The use of this type of technology allows rapid prototyping and application of reverse engineering. The team of the University of Ruse owns a series of 3D scanners - Artec Space Spider, Artec Eva and Artec Leo. The need to use different scanners is caused by the different size of the parts that are scanned. Artec's Space Spider scanner is the most accurate. It allows scanning of small objects and has the ability to capture details in models even the size of a coin. The accuracy that this scanner offers is 0.05 mm. The other two scanners are applicable for scanning large objects, with Artec Leo being the first to offer automatic processing in the scanner itself, as it is equipped with a powerful computing resource.
This does not require a computer connection during the scan. In addition, Artec Leo is the scanner that scans with the highest frequency. These scanners use structured light scanning technology and emit a light grid on the surface of the model. This light grating is refracted on the surface of the model and so the scanner records the geometry information of the model itself. The calculations are based on the principle of triangulation, where a triangle is formed between each point on the surface of the object, the light projector and the camera.
For the youngest visitors of the 53rd STROIKO exhibition, the University of Ruse has planned to hold a children's workshop, in which the possibilities of applied block programming will be shown in a language accessible to children. For this purpose, participants will use their own mobile devices and various robotic platforms - flying drones and ground robots. The main purpose of this workshop is to show children that there are real applications of the Pythagorean Theorem, the golden section, the Fibonacci sequence and thus to stimulate their interest in mathematics, physics and engineering.
