Kwadalwa ngo 05.18
Ukwakha izinhlelo zokusebenza eziqondene nawe, izinhlelo zokubona izimboni noma amadivayisi angaphakathi anamakhamera e-USB kuvame ukubambezeleka: ukuxhuma nokudlala okuyisisekelo kusebenza kumakhamera e-webcam, kodwa izilawuli ezicacile, ukuvumelanisa izithombe nokukala okudlula amadivayisi kudinga amathuluzi esofthiwe akhethekile. Abathuthukisi abaningi bayadidekaAma-SDK e-USB Camera nama-API e-USB Camera, bachitha isikhathi kumalungiselelo angahambisani noma baneliseke ngezici ezinganqamile.
Le mhlahlandlela ihlukanisa lezi zinsiza ngolimi olucacile lwabathuthukisi, igxile ekuhlukaniseni okuyisisekelo, ukuhlanganiswa kwehardware, ukukhethwa kwezinsiza, amaphutha ajwayelekile kanye nezimo zokusetshenziswa emhlabeni wangempela. Isebenza kubathandi abakha amakhamera okuphepha, abathuthukisi abangochwepheshe abasebenza emithonjeni yezokwelapha, kanye nabaklami abahlela ukuzenzakalelayo kwezomnotho.
Ukuhlukaniswa Okuyisisekelo: USB Camera API vs SDK (Azingashintshaniswa)
Ama-SDK nama-API asebenza ndawonye—awawashintshanisi. Indlela elula yokuwahlukanisa:
• API: Umthetho wokuxhumana wezinhlelo zakho ukuze zikhulume nekhamera.
• SDK: Ithuluzi eliphelele elihlanganisa i-API, ikhodi ebhalwe ngaphambilini, amabhuku nezinsiza zokudlula ekubhaleni ikhodi ephansi.
Iyini i-USB Camera API?
I-USB Camera API (Interface Yokuhlela Izinhlelo) iyisethi ejwayelekile yemithetho nemiyalo evumela ukuthi isoftware yakho ithumele izicelo (lungisa ukukhanya, thwebula amafremu, shintsha isixazululo) futhi yamukele idatha (ama-frame streams, izibuyekezo zestatus) kusuka kuhardware yekhamera.
I-lightweight, iyahambisana nezinkundla futhi ichaza kuphela ukuthi idatha igijima kanjani—akukho ikhodi noma amathuluzi akhiwe ngaphambili afakiwe. Isibonelo, i-API ichaza umyalo we-set_white_balance(), kodwa ishiyela ukuqhuba kwi-SDK noma kukhodi yakho eyenziwe ngokwezifiso.
Yini i-USB Camera SDK?
I-USB Camera SDK (Software Development Kit) iyiphakheji yokuthuthukisa yonke-enhlanganisela. Ihlanganisa i-API, kanye nezinqolobane zekhodi, amaphrojekthi wesampula, amathuluzi okudinga, imibhalo kanye nezixhumi zedrayivu.
Ama-SDK aguqula ama-API blueprints abe ikhodi esebenzisekayo, aphatha ukuxhumana kwe-hardware okuphansi, ukucubungula amafreyimu kanye nokuhambisana kwezinkundla. Lokhu kukuvumela ukuthi ugxile ezicini eziyisisekelo zohlelo lwakho esikhundleni sokwakha ukuhlanganiswa kwekhamera kusuka ekuqaleni.
Izivumelwano Ezimbili Eziyinhloko: UVC Standard vs Amathuluzi Eziphathwayo
Isofthiwe yekhamera ye-USB ihlukaniswe ngezigaba ezimbili—le nketho ithinta ngqo ukuhambisana, ukwenziwa ngokwezifiso kanye nokwandiswa.
UVC (USB Video Class): Izinga Elijwayelekile le-API
I-UVC iyizinga elivulekile, elingenazo izinkokhelo ezivela ku-USB Implementers’ Forum (USB-IF). Cishe wonke amakhamera e-webcam asetshenziswa abantu, amakhamera ezimboni ayisisekelo namakhamera e-USB angaphakathi asekelwa yi-UVC ngokwemvelo.
Ama-API e-UVC enza ukuxhuma nokudlala okuzenzakalelayo ku-Windows, macOS, Linux, Android kanye ne-iOS ngaphandle kwama-driver akhethekile, aphatha imisebenzi eyinhloko: ukusakazwa kwevidiyo, ukulungiswa kwezixazululo, izilawuli zokukhanya/ukuphambana kanye nokuthwebula izithombe eziyisisekelo.
