Izidingo zobuchwepheshe zamakhamera e-UAV

Izidingo zokucaca okuphezulu: Ukuze uhlangabezane nemisebenzi eyahlukene yokuthwebula izithombe zasemoyeni, ukuhlola nokuqapha, amakhamera e-UAV adinga ukuba nokulungiswa okuphezulu. Emkhakheni wokuthwebula izithombe zasemoyeni, ukulungiswa okuphezulu kungathwebula imininingwane yokuma kwezwe ethambile, njengalapho uthwebula izigcawu zasemadolobheni, ukwethula ngokucacile amakhonsathi ezakhiwo, ithrafikhi emigwaqweni, njll.; emsebenzini wokuhlola, ingakwazi ukubuyisela ngokunembile izici ze-topography ne-geomorph, inikeze izisekelo zedatha ezinembile zokumodela okulandelanayo kwezinhlangothi ezintathu nokuhlaziywa kwedatha. Ngokuvamile, iphikseli yamakhamera e-UAV asetshenziselwa izinjongo zobungcweti kufanele ifinyelele ngaphezu kuka-12mp, futhi eminye imikhiqizo esezingeni eliphezulu ize ifinyelele kumaphikseli ayizigidi ezingu-20 noma ngaphezulu, ehambisana nesinqumo esingahlangabezana namazinga afana no-4000×000dpi nangaphezulu.

Ukuminyana kwephikseli nekhwalithi yokucabanga: Ngaphezu kwenani lamaphikseli, ukuminyana kwamaphikseli nakho kubalulekile. Ukuminyana kwephikseli okunengqondo kungaqinisekisa ukuthi iphoyinti lephikseli ngalinye likwazi ukuzwa ngokugcwele ukukhanya endaweni ekhawulelwe ye-photosensitive element, kuncishiswe ukuphazamiseka phakathi kwamaphikseli, kanjalo kuthuthukiswe ukucaca nokumelwa kwemininingwane. Lapho eshutha okuqondiwe okukude, amakhamera anobuningi bephikseli ephezulu angathwebula izici zethagethi ngokucacile, agweme izimo ezifiphele noma ezihlanekezelwe. Isibonelo, uma iqapha izilwane zasendle ingadubula ngokucacile ukuthungwa koboya nokuziphatha kwesilwane.

Ukuzwela okuphezulu ukuze uvumelane nokukhanya okuyinkimbinkimbi: Indawo yendiza ye-UAV iyinkimbinkimbi, futhi izimo zokukhanyisa ziyashintsha, kusukela ekukhanyeni okunamandla kwasemini kuya ekukhanyeni okufiphele kokuhlwa nasebusuku, noma ezindaweni zethunzi, endlini, njll. Ngakho-ke, ikhamera idinga ukuba nokuzwela okuphezulu (ISO) ukuze ithwebule izithombe ezicacile nezinomsindo ophansi ngaphansi kwezimo zokukhanya okuncane. Ngokuvamile, inani elihle le-UAV ISO kufanele likwazi ukuzivumelanisa nezimo phakathi kwebanga elingu-100 - 6400 noma ngaphezulu. Uma udubula izibani zedolobha ebusuku, inani eliphakeme le-ISO lingaqinisekisa ukuthi ukukhanya kwesithombe kumaphakathi, futhi ngesikhathi esifanayo, umsindo ulawulwa ngobuchwepheshe bokunciphisa umsindo ukuze kuqinisekiswe ikhwalithi yesithombe.

Ububanzi obuguquguqukayo obubanzi bokugcina imininingwane: I-Wide dynamic range (WDR) ivumela ikhamera ukuthi igcine imininingwane kuzo zombili izindawo ezikhanyayo nezimnyama esithombeni. Uma kuthwebula izithombe zasemoyeni, kungase kuthwebule kokubili isibhakabhaka esikhanyayo nezinto ezimnyama ngesikhathi esisodwa. Amakhamera anobubanzi obubanzi obuguquguqukayo angavimbela isibhakabhaka ukuthi singachazi ngokweqile kanye nezinto eziphansi ukuba zibonakale ngokucacile ngaphandle kokulahlekelwa imininingwane. Isibonelo, lapho idubula ukuphuma kwelanga ngasolwandle, ingaveza ngokucacile ilanga futhi ibonise ukuthungwa kolwandle namagagasi.

I-autofocus esheshayo: Ngesikhathi sokundiza kwe-UAV, okuqondiwe kokudubula kungase kushintshe noma nini futhi indawo nebanga nakho akuzinzile, okudinga ukuthi ikhamera ibe nomsebenzi osheshayo we-autofocus. Ingakwazi ukuqedela ukugxila ngesikhathi esifushane (imvamisa phakathi kwamasekhondi angu-.5), ikhiye ngokushesha okuqondiwe, futhi iqinisekise ukuthi isithombe esishuthiwe sicacile futhi sibukhali. Lapho idubula imicimbi yezemidlalo, i-UAV ingagxila ngokushesha kubasubathi beminyakazo futhi ithwebule izikhathi ezijabulisayo.

Usizo lokugxila mathupha: Nakuba i-autofocus ifaneleka futhi ishesha, kwezinye izigcawu ezikhethekile, umsebenzi wokugxila owenziwe ngesandla unganikeza abasebenzisi ukulawula okunembe kakhudlwana Isibonelo, lapho uthwebula amakhro noma udinga ukujula okuthile komphumela wenkundla, abasebenzisi bangakwazi ukulungisa mathupha ibanga lokugxila ukuze bafinyelele izidingo zokudubula ezenziwe zaba ngezakho. Lapho uthwebula izimbali ezisondelene, ukugxila okwenziwa ngesandla kungalawula ngokunembile ukugxila ukuze kugqanyiswe imininingwane yembali.

I-Optical anti-shake isimamisa isithombe: Ngenxa yethonya lokudlidliza kwamaza omoya phakathi nendiza, ukusebenza kwekhamera okulwa nokuzamazama kubalulekile. Ubuchwepheshe be-Optical anti-shake bunxephezela ukususwa kwesithombe okubangelwa ukudlidliza ngesikhathi sangempela ngokuhlanganisa iqembu lamalensi anyakazayo ngaphakathi kwelensi, kwehlisa ngempumelelo izithombe ezilufifi. Lapho uthwebula izithombe zasemoyeni esimweni sezulu esinomoya, i-optical anti-shake ingagcina izithombe ezithwetshuliwe zizinzile, njengokungathi zisendaweni ezinzile.

Isengezo se-elekthronikhi esilwa nokuzamazama: Ngokungeziwe ku-optical anti-shake, ubuchwepheshe be-electronic anti-shake bungadlala indima ethile ekusimamiseni isithombe. Ihlaziya futhi icubungule idatha eqoqwe inzwa yesithombe futhi isebenzisa ama-algorithms ukulungisa ukususwa kwesithombe okubangelwa ukuzamazama. I-electronic anti-shake kanye ne-optical anti-sh isebenza ndawonye ukuze kuthuthukiswe umphumela wokulwa nokuzamazama kwekhamera ngaphansi kwezimo zendiza eziyinkimbinkimbi, iqinisekisa ikhwalithi yamavidiyo athwetshuliwe nezithombe.

Izinga eliphezulu lozimele levidiyo ebushelelezi: Kumavidiyo athwebula amakhamera e-drone, izinga eliphezulu lozimele liyisihluthulelo sokuqinisekisa ukushelela kwevidiyo. Ngokuvamile, isilinganiso sozimele esingu-30fps (ozimele ngesekhondi) noma ngaphezulu siyadingeka ukuze kuhlangatshezwane nezidingo zokuthwebula kwansuku zonke; kwezinye izigcawu ezidinga ukuthwebula ukunyakaza okusheshayo, njengezimoto ezihamba ngesivinini esiphezulu, izinyoni ezindizayo, njll., izinga lozimele kufanele lifinyelele ku-60fps noma ngisho no-120fps noma ngaphezulu, okunganciphisa ngempumelelo ukwehla futhi kwenze ividiyo ibe bushelelezi futhi ibe yemvelo.

Ukudubula okuqhubekayo okusheshayo ukuze uthwebule izikhathi: Uma uthwebula izigcawu ezithile ezidlulayo, umsebenzi wokudubula oqhubekayo osheshayo wekhamera muhle kakhulu. Ingakwazi ukuqhubeka ishutha izithombe eziningi ngesikhathi esifushane, inikeze abasebenzisi ukukhetha okwengeziwe ukuze baqinisekise ukuthi abaphuthelwa izikhathi ezijabulisayo. Uma kudutshulwa izigcawu ezifana nokuqhakaza nokuzingela izilwane, ukudubula okuqhubekayo kungathwebula izithombe ezijabulisayo ngezigaba ezahlukene.

Inkambu yokubuka efanele ukuhlangabezana nezidingo: indawo yokubuka inquma ububanzi besithombe ikhamera engasithwebula. Izimo zohlelo lokusebenza ezihlukene zinezidingo ezihlukene zenkundla yokubuka. Isibonelo, uma uthwebula izithombe, inkundla yokubuka enkudlwana iyadingeka, kanye nelensi ye-engeli ebanzi kakhulu ene-engeli engu-120° - 180° ifaneleka kakhulu kuyilapho ekuqashweni kwethagethi yebanga elide, inkambu encane yokubuka ingase idingeke ukuze usondeze impokophelo futhi ugqamise imininingwane, njengobude bokugxila obumaphakathi nobude obune-engeli engu-30° - 60°.

Ukuhlanekezela okuphansi kuqinisekisa ukunemba kwesithombe: Ukuhlanekezelwa kwelensi kungabangela ukuba isithombe esithwetshuliwe siwohloke, kuthinte ukunemba kobuhle besithombe. Amakhamera we-Drone kufanele asebenzise imiklamo yelensi yokuhlanekezela ephansi ukuze agcine izinga lokuhlanekezela lisezingeni eliphansi, ngokuvamile elidinga izinga lokuhlanekezela elingaphansi kwe-1 Lapho wenza imisebenzi yokuhlola nokuqapha, amalensi okuhlanekezela aphansi angaqinisekisa ukunemba kwedatha yokulinganisa futhi agweme amaphutha abangelwa ukuguqulwa kwesithombe.

Ukudluliswa kwedatha enesivinini esikhulu: Izithombe namavidiyo athwetshulwe yi-drone ikhamera kudingeka idluliselwe emuva esiteshini sokulawula phansi noma endaweni yokugcina ngesikhathi sangempela, esidinga amandla okudlulisa idatha ngesivinini esikhulu. Ubuchwepheshe bokudlulisa okungenantambo obufana ne-Wi-Fi, i-Bluetooth, noma amamojula azinikele okudlulisa izithombe ngokuvamile ayamukelwa, namazinga okudlulisela afinyelela ngaphezu kwezinga le-Mbps, okuqinisekisa ukudluliswa kwezithombe namavidiyo ngokushelelayo kanye nokunciphisa ukubambezeleka. Ezithombeni ezisakazwa bukhoma zasemoyeni, ukudluliswa kwedatha ngesivinini esiphezulu kuqinisekisa ukuthi izethameli zingabona izithombe ezicacile ngesikhathi esifanele.

Ukusekelwa kwesitoreji somthamo omkhulu: Ukugcina inani elikhulu ledatha yokudubula, ikhamera ye-drone idinga ukusekela amadivayisi wokugcina amandla, njengamakhadi e-SD, amadrayivu e-solid-state, njll. Umthamo wokugcina kufanele unqunywe ngokuya ngezidingo zangempela zokudubula, futhi ngokuvamile kunconywa ukuthi okungenani kube ngu-16GB. Ngemisebenzi yokudubula yesikhathi eside, enesinqumo esiphezulu, ungakhetha amadivaysi okugcina umthamo omkhulu we-64GB noma ngisho no-18GB ukuze uhlangabezane nezidingo zokudubula okuqhubekayo.

Zijwayelane nomthwalo we-drone: Umthamo wokuthwala umthwalo we-drone unomkhawulo, ukuze ugweme ukuthikameza ukusebenza nokukhuthazela kwendiza ye-drone, ikhamera idinga ukufeza i-miniaturization kanye nomklamo ongasindi. Ngaphansi kwesisekelo sokuqinisekisa ukusebenza, ikhamera nesisindo kufanele kwehliswe ngangokunokwenzeka. Isisindo sekhamera ye-drone yezinga lomthengi evamile siphakathi kwamashumi ambalwa amagremu kuya kumakhulu ambalwa amagremu, futhi amakhamera we-drone-grade nawo alawula isisindo ukuze aqinisekise ukuthi ifana nomthwalo wonke we-drone.

Isakhiwo esihlangene nokufakwa kalula: Ngokungeziwe esisindweni nevolumu, ukwakheka kwesakhiwo kufanele futhi kuminyene futhi kube lula ukukufaka ezindaweni ezihlukene ze-drone ngaphandle kokuthikameze ukusebenza kwendiza eyi-drone. Indlela yokufaka yekhamera kufanele ibe njalo futhi ithembeke, futhi kufanele ihlale izinzile phakathi nokundiza kwendiza, igweme ukuxega noma ukulimala kwekhamera ngenxa yokudlidliza noma ukungqubuzana.
