Abantu bahlala bebuza, zeziphi iimpawu ze-wireless high-definitionisidlulisi ividiyokunye nomamkeli?Sithini isisombululo sevidiyo esasazwa ngaphandle kwamacingo?Umgama omde kangakanani onokuwufikelela kwi-drone camera transmitter kunye ne-receiver?Ukulibaziseka kwantoniIsidluliseli sevidiyo ye-UAVkumamkeli?
Umbono we "Ukuhanjiswa kwevidiyo ye-drone HD"Iye yathandwa iminyaka embalwa, kwaye i-DJI ifanelwe ikhredithi eninzi malunga nendlela ngokukhawuleza ingcamango isasazeke ngayo. Ikhonkco lokusasaza ividiyo engenazingcingo liya litshisa nge-UAV. I-DJI yenza i-UAV kunye ne-drones idume kumashishini abantu aphilayo kunye neendawo ezahlukeneyo.
I-wireless drone transmitter kunye nenkqubo yokusebenza yomamkeli njengalapha ngezantsi:
Ikhamera ekwibhodi iqhagamshela nomthumeli wevidiyo yedijithali--- umthumeli wevidiyo uthumela ngaphandle kwamacingo ifidi yevidiyo kumamkeli wevidiyo-- umamkeli uqhagamshela ne-GCS---GCS ibonisa umjelo wevidiyo ebantwini abasemhlabeni.
Isidluliseli sevidiyo seDrone HDkwaye umamkeli uneempawu ezi-3 ezibalulekileyo:
● IHD
●Ubuthi xhaxhe
● Umgama omde
Ezi mpawu zintathu zezona zinto zixhalatyelwe kakhulu ngabasebenzisi bedrone kunye noko bahlala bengakuqondi.Kweli nqaku siza kuchaza ezi ngongoma zi-3.
Ingcaciso ephezulu
"Inkcazo ephezulu" kwi-drone ephezulu-definition yevidiyo yosasazo eneneni yahluke kancinane kwimbono ye-HD TV.Imigangatho yenkcazo ye-TV yile: inkcazo ephezulu (720P), i-HD epheleleyo (1080P), i-ultra High definition (4K).Le migangatho ye-HD ibonakaliswe ngesisombululo.Ngale ndlela, kukho ingqwalasela encinci ehlawulwe kumbono "wezinga lokusasazwa kwevidiyo."
Ngokusekwe kwividiyo ye-HD epheleleyo, ukuba izinga lomlambo lihlukile, ubukhali bevidiyo buya kwahluka.Ukuba izinga lomlambo liyafana.Nangona kunjalo, usebenzisa iindlela ezahlukeneyo zokucinezela ividiyo, umgangatho wevidiyo uya kwahluka.
Uxinzelelo olukhankanywe ngasentla yindlela yokucinezela ividiyo.I-H.264 kunye ne-H.265 ziindlela eziqhelekileyo zokucinezela ividiyo.Nangona kunjalo i-h.265 bubuchwepheshe obuphezulu kune-H.264.
Kutheni iividiyo kufuneka zicinezelwe?Makhe ndikubonise i-equation: Isekondi enye yedatha ye-1080P60 ividiyo yi-1920*1080*32*60=3,981,312,000 bits, emalunga ne-4Gb/s.Kwanokusebenzisa i-fiber optics ukuhambisa inani elikhulu kangaka ledatha kuthatha ixesha.Singasathethi ke ngokusebenzisa ikhonkco elilinganiselweyo lokuhambisa i-wireless ukusasaza umjelo omkhulu wevidiyo.Ke imibutho yezizwe ngezizwe ivumelene ngomgangatho kunye nendlela ecinezela ividiyo yokuhanjiswa kunye ne-decompresses emva kokuyifumana.
Ukusebenza koxinzelelo lwe-H.265 kuphindwe kabini kune-H.264.Ividiyo ixinaniswe yi-H.265 isezantsi kwi-bit rate kune-compressed yi-H.264.Ke ngoko, "i-HD" kwividiyo ye-hd yokuhanjiswa kweedrones, ukuqonda okunengqiqo ngakumbi kufuneka kube yividiyo ekumgangatho ophezulu.
Isisombululo esifanayo kunye nendlela yocinezelo olufanayo lwe-encoding, okukhona isantya sesuntswana siphezulu, kokukhona umgangatho wevidiyo ungcono.
Isisombululo esifanayo kunye nesantya se-bit efanayo, indlela yoxinzelelo lwekhowudi ye-H.265 inomgangatho ongcono womfanekiso kune-H.264.
Ukuze ukwazi ukuthumela imijelo yevidiyo ecacileyo ngakumbi kubasebenzisi, bonkeI-WIAVE amakhonkco angenazingcingo edronesebenzisa i-H.264 + H.265 i-algorithms kunye nezikhowudi ezakhelwe ngaphakathi kunye nezidikhowuda ngaphakathi kwisidlulisi kunye nomamkeli.
Ukubambezeleka
"Zero latency" ngumbono oye wakhuthazwa ngabavelisi abaninzi.
"Iziro ulibaziseko" eneneni ingcamango ehambelanayo.Ixesha elibonakalayo lokugcinwa kweliso lomntu li-100 ~ 400ms.Ke ngoko, "ukulibaziseka kungabikho" yinjongo ezilandelwa zizo zonke iinkqubo zonxibelelwano lwexesha lokwenyani kodwa azinakufezekiswa.Kwaye kweyona nkqubo yokusetyenziswa, ukulibaziseka okubonwa liliso lomntu nako kuvela ekulibazisekeni kwekhamera kunye nomboniso we-GCS.Ukulibaziseka kokudluliselwa kwamacingo yinxalenye kuphela yalo.
I-IWAVE drone digital downlink latency imalunga ne-20-80ms ukusuka kwi-transmitter ebhodini kunye nomamkeli emhlabeni.
Umgama omde
Uluhlu olude kulula ukuluqonda, yingxaki yeRF ebanzi.Okwangoku, iimveliso ezininzi zongeza i-"LOS" xa imakisha umgama wonxibelelwano (i-LOS ibhekisa kumgama olinganisiweyo emoyeni ovulekileyo ngaphandle kokuphazamiseka).
Iqela le-IWAVE R&D ligxile kuluhlu olwahlukeneyo lwevidiyo kunye nekhonkco lonxibelelwano lwedatha ye-telemetry yedrone, i-UGV, i-UAV kunye ne-USV.
