| Abstract | Bespilotnim se letjelicama smatraju sve letjelice kojima je bez posade omogućeno kretanje po zraku. Osnovna podjela bespilotnih letjelica prema načinu upravljanja je podjela na dronove i daljinski upravljane letjelice. Uz to bespilotne se letjelice mogu razvrstati prema raznim karakteristikama, kao što su masa, brzina, domet, maksimalna visina, vrsta motora i vrsta tereta. Njihova je primjena postala rutinska i uobičajena u vojnim aktivnostima, no u posljednje vrijeme sve više svjedočimo primjeni bespilotnih letjelica i u civilne svrhe (nadzor elektroenergetskih vodova, naftovoda, granica, šumskih požara, poplava, zaprašivanja polja, zračno fotografiranje, analiza terena, poljoprivreda, šumarstvo). Korištenje dronova u pošumljavanju uključuje snimanje terena, obradu prikupljenih podataka i konačnu izvedbu prijenosa i sadnje sjemenki na detektiranim područjima. Svrha rada bila je osmisliti i preraditi dron Ryze Tech Tello drone- powered by DJI kako bi mogao prihvatiti predmet (zemlju, sjeme, sadnicu, prihranu) te ga otpustiti na željenoj lokaciji s ciljem utvrđivanja mogućnosti primjene drona u pošumljavanju. Temelj kvalitetnog modela sustava za pošumljavanje je dobra analiza terena i pronalazak mjesta na kojem se ispuštaju sjemenke. Za uspješnu izvedbu tog zadatka bilo je potrebno modificirati kut kamere i napisati programski kod kojim dron na temelju računalnog vida detektira oznake mjesta na kojima treba ispustiti sjeme. Pokazalo se da ovaj dron predstavlja dovoljno dobro sredstvo modeliranja kompleksnih zadataka. |
| Abstract (english) | Unmanned aerial vehicles are all aircraft without any passengers, pilot or any other crew members on board. The basic division of UAV according to its control method is the division into drones and remote-controlled aircraft. In addition, drones can be classified according to various characteristics, such as mass, speed, range, maximum altitude, type of engine and type of cargo. Their use has become routine and common in military activities, but recently we are increasingly witnessing the use of drones for civilian purposes (surveillance of power lines, oil pipelines, borders, forest fires, floods, field dusting, aerial photography, terrain analysis, agriculture, forestry). The use of drones in afforestation involves field surveying, processing of the collected data, and final performance of seed transfer and planting in the detected areas. The purpose of the work was to design and redesign the Ryze Tech Tello drone- powered by DJI so that it could transfer the object (soil, seeds, seedlings, top dressing) and release it at the desired location in order to determine the possibility of using the drone in afforestation. The basis of a quality model of afforestation system is a good analysis of the terrain and finding a place where the seeds are released. To successfully perform this task, it was necessary to modify the angle of the camera and write program code by which the drone, based on computer vision, detects the markings of the places where the seed should be dropped. It has been shown that this drone is an adequate modelling tool for complex tasks. |
