Kulesi sihloko, sizochaza ukuthi kungani le mihluko ikhona, ukuthi ama-audio-enabled.USB amakhamera amamojulasebenza, lapho udinga khona, nokuthi ungakhetha kanjani eyodwa efanele—konke kugxile ekucaciseni kokubili abathandi bezobuchwepheshe nabasebenzisi bezinsuku zonke.
1. Iziqalo: Indlela Ama-USB Camera Modules Asebenza Ngayo (Futhi Kungani Umsindo Ungakhethwa)
Ukuze siqonde ukuthi kungani umsindo ungawona wonke ama-module we-USB camera, masiqale ngezisekelo. Inhloso eyinhloko ye-module ye-USB camera ukuqoqa idatha yevidiyo (ukukhanya okuhunyushwe kube ama-pixel edijithali) bese kuyidlulisa kudivayisi yokusingatha (ilaptop, i-Raspberry Pi, i-IoT gateway) nge-port ye-USB. Le nqubo ithembele ezicini ezimbili ezibalulekile:
• Isithombe sensori (e.g., CMOS noma i-CCD) sokuthwebula ividiyo.
• I-USB controller ethobela izivumelwano ezithile zevidiyo (njenge-USB Video Class, noma i-UVC) ukuze ithumele idatha phezu kwe-USB bus.
I-Audio, ngokuphambene, iyindlela yedatha ehlukile enezinsiza zayo kanye nezivumelwano. Ukuze i-USB camera module iqophe i-audio, idinga ingxenye eyengeziwe: i-microphone (noma i-microphone array) ehambisana nomlawuli we-audio osebenzisa i-USB Audio Class (UAC) protocol.
Kungani Amamojula Amaningi Eskipha Umsindo
Abakhiqizi baphuthelwa umsindo ngezizathu ezintathu eziyisisekelo:
• Ukusebenza kahle kwezindleko: Ukwengeza i-microphone, umphathi wezwi, kanye nezinsiza zokukhansela umsindo kukhuphula izindleko zokukhiqiza. Ezimweni zokusetshenziswa ezigxile ebhajetheni (isb., ukuqapha ividiyo okuyisisekelo, amadivayisi e-IoT aphansi), imodyuli ezinevidiyo kuphela zikhona emncintiswaneni.
• Izithiyo zokwakha: Amamojula e-USB anobukhulu obuncane (ajwayelekile kumadroni, izinto ezigqokwayo, noma izinhlelo ezihlanganisiwe) anendawo encane. Ukubeka phambili izinzwa zevidiyo nezibuko kuvame ukushiya akukho ndawo yokufaka ama-microphone.
