abstract / sažetak
The aging and deterioration of bridges is becoming an increasing burden for transportation management systems as it requires increasing investments for the proper maintenance of a large number of bridges. Significant savings can be achieved by timely maintenance work. To achieve this, it is necessary to improve existing methods of inspection and monitoring of the condition of bridges to make their implementation cheaper, faster, and more reliable. In the last ten years, a significant number of unmanned aerial vehicles have appeared on the market. This paper presents their applicability for assessing the condition of bridges. It includes the following: important characteristics and selection criteria of unmanned aerial vehicles and associated equipment for collecting data on the condition of bridges; a description of the application of unmanned aerial vehicles to conduct a visual inspection on bridges; possibilities of monitoring bridges using data recorded by the unmanned aerial vehicle; a review of the key shortcomings that limit their application in everyday practice.
Starenje i degradacija mostova postaje sve veći teret za sustave gospodarenja prometnom infrastrukturom s obzirom da zahtijeva sve veća ulaganja u održavanje velikog broja mostova. Značajne uštede mogu se ostvariti pravovremenom izvedbom radova održavanja. Da bi se to postiglo, nužno je unaprijediti postojeće metode pregleda i praćenja stanja mostova kako bi njihovo provođenje postalo jeftinije, brže i pouzdanije. Na tržištu se u posljednjih desetak godina pojavio velik broj bespilotnih letjelica, a njihova primjenjivost za ocjenu stanja mostova prikazana je u ovom radu. Rad uključuje sljedeće: prikaz karakteristika i kriterija odabira bespilotne letjelice i pripadne opreme za prikupljanje podataka o stanju mostova; opis primjene bespilotnih letjelica za provedbu vizualnog pregleda; mogućnosti monitoringa mostova koristeći bespilotne letjelice; osvrt na ključne nedostatke koji ograničavaju njihovu primjenu u svakodnevnoj praksi.
