Od ideje o kupnji drona do gotovog izvještaja o izrađenom elaboratu
Upotreba bespilotnih letjelica u geodetskom snimanju postaje sve češća praksa, što nam dopušta da za nekoliko sati snimimo područja veća od 10 do čak 1000 hektara, ovisno o zadaći koju smo dobili.
Na tržištu postoji mnogo različitih vrsta bespilotnih letjelica, od multicoptera, preko „fixed wing“ aviona do hibrida. Prvi izazov s kojim se susrećemo je odabrati letjelicu koja optimalno odgovara našim potrebama.
U prvom dijelu predavanja predstavit ćemo tehničke specifikacije bespilotnih letjelica ključnih za geodetsku uporabu, planiranje leta, te postupak upravljanja letjelicom.
Prezentirat ćemo najbolju praksu za snimanje podataka, postavljanje kontrolnih točaka i prijeći skupa optimalne parametre za let drona.
U drugom dijelu pokrit ćemo osnove fotogrametrije, odnosno ono najvažnije- kako dobiti podatke koje ćemo moći koristiti u službi inženjerske geodezije kojom se bavi naveći broj nas geodeta. Proći ćemo kroz glavne faze obrade fotografija, te naučiti sve o terminima i napraviti georeferenciranje, izračun oblaka točaka, izračun modela terena, izračun ortofota. Naučiti razliku između DTM-a i DSM-a, te DOF-a i true DOF-a.
U trećem dijelu predavanja pokazat ćemo na praktičnim primjerima računanja koja možemo napraviti na dobivenim podacima mjerenja iz drugog dijela predavanja.
U završnom dijelu, dat ćemo vam primjere klasičnih geodetskih zadaća, projekata, u kojima smo implementirali snimanje tehnologijom bespilotnih letjelica, obradili fotogrametrijske podatake u željeni prikaz, predstaviti mogućnosti izvoza podataka u treće CAD programe, te analizirati ekonomičnost predstavljene tehnologije.
Meet your host – Vid
- 4 years of traditional land surveying experience
- 8+ years of experience in aerial photogrammetry
- 300+ drone photogrammetry projects
Vid has always been fascinated with technology and its potential in making our lives easier.
Having joined our team as a student, he has dedicated himself to research and development, and has since more than earned his current position of technical director.
“I’ve always been a little obsessed with the prospect of doing things smarter … and nothing pleases me more than finding new, better, and faster ways of doing my job.”
In that sense, transitioning from traditional surveying methods to modern aerial photogrammetry was a completely natural and logical progression. And not just for Vid, but for our whole team.
“There are just so many moving parts you have to take into account … I mean, it’s not just about going out into the field, taking some measurements, and then simply finishing up with the job.
There’s planning, safety concerns, accuracy, time spent in the field, gear, resources, teamwork, not to mention reaching your business goals. And there are ways of optimising those processes.
There are better tools, plans, and techniques. And if a more efficient and productive way is possible, wouldn’t you take it?”
Optimal control over your workflows and processes, better measuring accuracy, and significant improvements in productivity are just some of the perks to be gained in terms of generally upgrading the way we survey.
Today, we can safely reach and measure what used to be almost unreachable. We can complete more projects in less time. We can do so much more without even being in the field. There’s so much potential to be taken advantage of.
“Change is only scary if it’s for the worse. As long as it benefits us, we should strive towards it. And if I can contribute to helping my surveying colleagues work smarter, and achieve their goals a little faster, while even earning them some extra free time to top it all off … I’ll just do my best!
