| Abstract | Do prije desetak godina dronovi su bili samo dječje igračke na daljinsko upravljanje. Danas se nalaze posvuda, a i tržište dronova sve je jače, raznovrsnije i cjenovno pristupačnije.
U današnje se vrijeme termin dron upotrebljava kao naziv za sve bespilotne letjelice. Riječ dron dolazi od engleskog 'drone' (eng. drone-bumbar) koja označava zujanje. Ista se riječ u govoru upotrebljava i za quadcopter, iako bi primjereniji naziv za sve letjelice bio 'UAV' koji označava zračnu letjelicu bez pilota (eng. Unmanned Aerial Vehicle).
Svaka se bespilotna letjelica kontrolira daljinskim upravljačem preko bežične veze ili može letjeti samostalno uporabom unaprijed programiranog leta. Također, moguće je pomoću GPS-a dron orijentirati na praćenje lokatora i snimanje određenog objekta.
Opremljeni su raznim senzorima: žiroskop, kompas, visinomjer, GPS sustav, infracrvena kamera, digitalna kamera, radar, sonar, termometar...
Napredniji modeli posjeduju i kameru povezanu mobilnim telefonom (eng. Smartphone) koji putem video linka omogućuje 'Live prijenos' kao promatranje slike uživo na letjelici. Fotografija snimljena dronom može biti različitih karakteristika i kvalitete, ovisno o vrsti drona i položaju kamere. Kako bi kamera mogla nepomično i mirno stajati tijekom uporabe, sve se više upotrebljava gimbal koji predstavlja 'support system'.
Povećanjem broja senzora došlo je do širenja njihove upotrebe. Prva ih je koristila vojska, a danas ih koriste meteorolozi za predviđanje vremena, geografi i geolozi za pristup neistraženim područjima i mapiranje, poljoprivrednici za nadzor obradivih površina, policija za kontrolu granica, elektroprivreda za nadzor i inspekciju strujnih vodova, katastar za kontrolu zemljišnih knjiga, službe za organizaciju ljudstva i sredstava nakon katastrofe.
Iako im je primjena široka, u ovom radu pisat će se o video snimanju dronovima jer donose spektakularne snimke iz zraka otvarajući potpuno novu perspektivu. |
| Abstract (english) | Until about ten years ago drones were only toys with remote control. Today they are everywhere and drone market is stronger, more diverse and more affordable.
Nowadays the term drone is used as a name for all drones. The word comes from the English 'drone' (eng. Drone-bee), which indicates the buzz sound. The same word is used as a slang for quadcopter, although a more appropriate name for all aircraft would be 'UAV' which means an unmanned aerial vehicle, (eng. Unmanned Aerial Vehicle).
Each unmanned aircraft is controlled by remote control via a wireless connection or can fly autonomously using a pre-programmed flight. Also, it is possible for a drone to track a locator on certain subject using GPS.
Drones are equipped with various sensors: gyroscope, compass, altimeter, GPS system, infrared camera, digital camera, radar, sonar, thermometer ...
More advanced models have the camera connected to a mobile phone (Smartphone) who by video link allows 'live transmission' as watching live images on the aircraft. Photos captured by drone may be different characteristics and quality, depending on the type of drone and the camera position. How this could still, stand still during use, is increasingly being used gimbal that represents 'support system'.
By increasing the number of sensors also spread their use. The first of them was used by the army, and today they are used by meteorologists to predict the weather, geographers and geologists to access unexplored areas and mapping, farmers for control of arable land, police border control, power supply for control and inspection of power lines, land for control of land registers, services for the organization of personnel and resources after a disaster.
Despite their broad application, in this paper we'll write about the video shooting drones because they bring spectacular shots from the air by opening a brand new perspective. |
