Isingeniso
Embonini yokuthwebula amafilimu, amasistimu okudlulisa amavidiyo anezintambo zendabuko aya ngokuya engakwazi ukuhlangabezana nezidingo zokuguquguquka nokusebenza kahle ekukhiqizweni kwefilimu yesimanje ngenxa yezinkinga ezifana nekhebula eliyinkimbinkimbi kanye nokuhamba okulinganiselwe. Isibonelo, ezimeni ezibandakanya ukuthwebula kwesigcawu esiguqukayo, ukuthwebula kwezithombe zasemoyeni nge-drone, noma ukuxhumana kwamakhamera amaningi, ukudluliswa kwezintambo kuvamise ukuphumela ekukhawulweni kwama-engeli okudubula, ubunzima bokunyakaza kwezinto, kanye nokubambezeleka okungaba khona okubangelwa ukwehluleka kwentambo.
Ukwengeza, ubuchwepheshe bokudlulisa okungenantambo bendabuko (isb., i-microwave) buhlushwa ikhwalithi yesithombe esingesihle, ukubambezeleka okuphezulu, namandla abuthakathaka okumelana nokuphazamiseka, okubenza bangafaneleki ukudubula okucacayo nokuqapha ngesikhathi sangempela.

Ingemuva
Kulesi simo, i-Imojula yokudlulisa ividiyo engenantambo ye-IWAVEkuye kwavela njengesixazululo esisha sembonini yokuthwebula amafilimu, ngenxa yamakhono ayo okuxhumana okungewona umugqa wokubona (NLOS), umkhawulokudonsa ophezulu, nokubambezeleka okuphansi. Le mojula ifaneleka kakhulu ukudluliselwa kwevidiyo yesikhathi eside ekude ezindaweni eziyinkimbinkimbi, njengokuthwebula indawo enkulu yangaphandle, ukuthwebula izithombe zasemoyeni nge-drone, nokusakaza bukhoma kwamakhamera amaningi.
Uhlelo lwephrojekthi
1.Izimo Zohlelo Lokusebenza Nezimfuneko
Ukudubula Okudidiyelwe Kwekhamera Eningi:
Emikhiqizweni emikhulu yefilimu noma yemidlalo ye-TV, amakhamera eselula amaningi adinga ukudlulisa izithombe ezinencazelo ephezulu abuyele egumbini lokulawula ngesikhathi sangempela, okuvumela abaqondisi ukuthi balungise izithombe ngokushesha.
I-Drone Aerial Photography:
Uma ama-drones afakwe amakhamera okudubula endaweni ephakeme noma ebangeni elide, adinga ukudluliswa okuzinzile kwezithombe ze-4K/8K ezinempendulo yomyalo wokulawula ukubambezeleka okuphansi.
Outdoor Complex Environment Shooting
Ezimeni ezingezona umugqa wokubona njengezintaba, amahlathi, noma izindawo zasemadolobheni eziminyene, izinkinga zokuthiywa kwezimpawu kufanele zinqotshwe.
2. I-System Architecture Design
Ukuthunyelwa kwezingxenyekazi zekhompuyutha:
Imojula ye-FDM-66MN transmitter ihlanganiswe nekhamera, isekela okokufaka kwesikhombimsebenzisi se-IP futhi, uma kunesidingo, i-HDMI/SDI, iyenze ihambisane namakhamera webanga lesinema ajwayelekile (isb, ARRI Alexa, RED Komodo).
Umamukeli usetshenziswa evenini yokusakaza noma isikhungo sokukhiqiza ngemuva, esinamadivayisi athola amashaneli amaningi avumela ukuhlanganisa amasignali nokuvumelanisa.
Ukudluliswa kwe-Cascaded (isb, ama-relay node) kuyasekelwa, kunweba ibanga lokudlulisela libe ngaphezu kwamakhilomitha ayi-10.
Ukucushwa Kwenethiwekhi:
Imojula isebenzisa ubuchwepheshe bokwabiwa kwe-dynamic spectrum ukugwema ukuphazamiseka kwamanye amadivaysi angenawaya esizeni (isb, i-WiFi, i-walkie-talkies).
Izivumelwano zokubethela ziqinisekisa ukuvikeleka kwedatha yevidiyo, zivimbela ukuvuza kokuqukethwe.
3. Amacala Okufaka Isicelo
Ikesi 1: Umbukiso Wangempela Wangaphandle Wesikali Esikhulu
Ngesikhathi sokudutshulwa kombukiso wangempela ezindaweni ezisezintabeni, imojula ye-FDM-66MN yasetshenziselwa ukudluliswa kwesignali phakathi kwamakhamera amaningi eselula nama-drones. Ama-Relay node anike amandla ukumbozwa kwesignali ezindaweni ezingezona ulayini wokubona, afinyelela ibanga lokudlulisela elingamakhilomitha angu-8, ngokubambezeleka okungaphansi kwama-50ms nokusekelwa kokuqapha kwe-4K/60fps kwesikhathi sangempela.
Icala 2: Ukudutshulwa Kwesigcawu Sempi se-Movie
Esigcawini senkundla yempi esinemiphumela yokuqhuma okukhulu, amandla emojuli okumelana nokuphazamiseka aqinisekise ukudluliswa okuzinzile kwezithombe zamakhamera amaningi, kuyilapho isici sayo sokubethela sivikela okuqukethwe okungakhishiwe.
Izinzuzo
1. Amapharamitha Obuchwepheshe kanye Namaphuzu Avelele Wokusebenza
Ibanga Lokudlulisela: Isekela amakhilomitha angaphezu kuka-10 esimweni somugqa wokubona kanye nekhilomitha elingu-1-3 i-hop ngayinye ezindaweni ezingezona umugqa wokubona.
Ububanzi nokulungiswa: Isekela kufika ku-8K/30fps noma 4K/60fps, ngama-bitrate alungisekayo (10-30Mbps), futhi ihambisana nombhalo wekhodi we-H.265 ukuze unciphise ivolumu yedatha.
Ukubambezeleka Ukubambezeleka: Ukubambezeleka kokudluliselwa kokuphela kuya ekupheleni kungu-≤50ms, kuhlangabezana nezimfuneko zokuqapha kwesikhathi sangempela nokuhlela okuvumelanisiwe.
Amandla Okumelana Nokuphazamiseka: Isebenzisa ubuchwepheshe be-MIMO-OFDM kanye nokugxuma kwamafrikhwensi ashukumisayo ukuze ivumelane nezimo eziyinkimbinkimbi zokuphazamiseka.
Ukuphepha: Isekela ukubethela kwe-AES-128, ithobelana nezidingo zobumfihlo bokuqukethwe kwemboni yefilimu.
2. Ukuphumelela Uma Kuqhathaniswa Nezixazululo Zendabuko
I-Non-Line-of-Sight Transmission: Ngokubonisa isignali ehlakaniphile kanye nobuchwepheshe bokudlulisa, inqoba imikhawulo yamadivayisi avamile angenantambo athembele ekudluliselweni komugqa wokubona, okuyenza ifanelekele izimo ezivimbelwe indawo yasemadolobheni noma yemvelo.
Ukuvumelana Okuphezulu: Idizayini ye-modular ivumela ukuhlanganiswa okusheshayo emishinini yokudubula ehlukahlukene (isb, ama-gimbal, ama-drones, iziqinisi eziphathwa ngesandla), ukunciphisa izindleko zokuzilungisa.
Ukusetshenziswa kwamandla aphansi kanye ne-Lightweight: Ngokusetshenziswa kwamandla okungaphansi kuka-5W nesisindo esingu-50g kuphela, ilungele ama-drones amancane noma amadivayisi aphathekayo.
Inani Namathemba Ekusasa
Ukusetshenziswa kwesidlulisi sevidiyo esingenantambo se-IWAVE kukhulisa kakhulu ukuguquguquka nokusebenza kahle kokushuthwa kwefilimu, ikakhulukazi ekushutheni endaweni kanye nasekukhiqizweni kwemiphumela ekhethekile. Ukuthembeka kwayo okuphezulu nokubambezeleka okuphansi kunikeza abaqondisi inkululeko enkulu yokudala. Ngokuzayo, ngokuhlanganiswa kobuchwepheshe be-5G ne-AI, imojula ingase ithuthukiswe ngokwengeziwe ibe inethiwekhi yokudlulisela ehlakaniphile, ivumele ukulungiswa kwe-bitrate okuguquguqukayo kanye nokuxilongwa kwephutha elihlakaniphile, ngaleyo ndlela iqhubekisele imboni yokukhiqiza amafilimu ekuxazululeni okungenazintambo ngokugcwele nezihlakaniphile.
