Anthu nthawi zambiri amafunsa, ndi makhalidwe ati opanda zingwe mkulu-tanthauzochopatsira kanemandi wolandila?Kodi mavidiyo omwe amaseweredwa popanda ziwaya amatha bwanji?Kodi chotumizira ndi cholandila cha kamera cha drone chingafikire mtunda wautali bwanji?Kuchedwa kwatani?UAV kanema transmitterkwa wolandira?
Lingaliro la "drone HD kanema kufala"Zakhala zotchuka kwa zaka zingapo, ndipo DJI akuyenera kutamandidwa kwambiri chifukwa cha momwe lingaliroli lafalikira mofulumira. Ulalo wotumizira mavidiyo opanda zingwe ukuyamba kutentha kwambiri ndi UAV. DJI imapangitsa UAV ndi drones kukhala otchuka m'makampani amoyo ndi osiyanasiyana.
Wotumiza opanda zingwe wa drone ndi njira yogwirira ntchito yolandila monga ili pansipa:
Kamera yomwe ili m'bwalo imalumikizana ndi wotumiza makanema apa digito--- wotumiza makanema amatumiza chakudya chamavidiyo opanda zingwe kwa wolandila makanema-- wolandila amalumikizana ndi GCS---GCS amawonetsa mavidiyowo kwa anthu omwe ali pansi.
Drone HD kanema transmitterndipo wolandila ali ndi zinthu zitatu zofunika:
● HD
● Kuchedwa kulibe
● Mtunda wautali
Zinthu zitatuzi ndi zomwe ogwiritsa ntchito ma drone amakhudzidwa kwambiri nazo komanso zomwe nthawi zambiri samamvetsetsa.M’nkhaniyi tifotokoza mfundo zitatu zimenezi.
Tanthauzo Lapamwamba
"Tanthauzo lapamwamba" pakufalitsa mavidiyo otanthauzira kwambiri a drone kwenikweni ndi losiyana pang'ono ndi lingaliro la HD TV.Tanthauzo la miyezo ya TV ndi: kutanthauzira kwakukulu (720P), HD yonse (1080P), kutanthauzira Kwambiri Kwambiri (4K).Miyezo iyi ya HD imadziwika ndi kusamvana.Mwanjira iyi, pali chidwi chochepa chomwe chimaperekedwa ku lingaliro la "kuthamanga kwamavidiyo."
Kutengera kanema wathunthu wa HD yemweyo, ngati kuchuluka kwa mtsinje kuli kosiyana, kuthwa kwa kanema kudzakhala kosiyana.Ngati mlingo wa mtsinje uli wofanana.Komabe, pogwiritsa ntchito njira zosiyanasiyana zophatikizira makanema, mawonekedwe a kanema amakhala osiyanasiyana.
The psinjika tatchulazi ndi njira compress kanema.H.264 ndi H.265 ndi wamba njira compressing kanema.Komabe h.265 ndiukadaulo wapamwamba kwambiri kuposa H.264.
Chifukwa chiyani mavidiyo amafunikira kupanikizidwa?Ndiroleni ndikuwonetseni equation: Sekondi imodzi ya data ya kanema wa 1080P60 ndi 1920*1080*32*60=3,981,312,000 bits, yomwe ili pafupifupi 4Gb/s.Ngakhale kugwiritsa ntchito ma fiber optics kufalitsa kuchuluka kwa deta kumatenga nthawi.Osatchulanso kugwiritsa ntchito ulalo wocheperako wopanda zingwe wama bandwidth kuti utumize kanema wamkulu chotere.Chifukwa chake mabungwe apadziko lonse lapansi agwirizana pa muyezo ndi njira yomwe imakanikiza kanema kuti atumizidwe ndikuwonongeka atalandira.
Kuphatikizika kwa H.265 kuwirikiza kawiri kuposa H.264.Kanema woponderezedwa ndi H.265 ndi wotsika kwambiri kuposa wothinikizidwa ndi H.264.Chifukwa chake, "HD" mu kanema wa kanema wa HD wa drones, kumvetsetsa koyenera kuyenera kukhala kanema wapamwamba kwambiri.
Kusamvana komweko komanso njira yokhotakhota yofananira, kukwezeka pang'ono, kumapangitsa kuti kanemayo akhale wabwino.
Chomwecho kusamvana ndi mlingo womwewo pang'ono, ndi psinjika coding njira H.265 ali bwino fano khalidwe kuposa H.264.
Kuti athe kutumiza mavidiyo omveka bwino kwa ogwiritsa ntchito, onseWIAVE drone opanda zingwekutengera ma aligorivimu a H.264+H.265 ndi ma encoder omangidwira ndi ma decoder mkati mwa chopatsira ndi cholandirira.
Kuchedwa
"Zero latency" ndi lingaliro lomwe lapangidwa ndi opanga ambiri.
"Zero kuchedwa" kwenikweni ndi lingaliro wachibale.Nthawi yosungira diso la munthu ndi 100 ~ 400ms.Chifukwa chake, "zero kuchedwa" ndicholinga chomwe njira zonse zolumikizirana zenizeni zimatsata koma sizingakwaniritse.Ndipo pamagwiritsidwe enieni, kuchedwa komwe kumawonedwa ndi diso la munthu kumabweranso chifukwa chakuchedwa kwa kamera ndi chiwonetsero cha GCS.Kuchedwa kwa kufalitsa opanda zingwe ndi gawo chabe.
IWAVE drone digital downlink latency ili pafupi 20-80ms kuchokera pa transmitter pa bolodi ndi wolandira pansi.
Mtunda Wautali
Utali wautali ndi wosavuta kumva, ndivuto lalikulu la RF.Pakadali pano, zinthu zambiri zimawonjezera "LOS" polemba mtunda wolumikizana (LOS imatanthawuza mtunda woyezedwa panja popanda kusokonezedwa).
Gulu la IWAVE R&D limayang'ana kwambiri maulalo osiyanasiyana amakanema amakanema ndi ma telemetry a drone, UGV, UAV ndi USV.
