Kwadalwa ngo 09.03
Isingeniso: I-Demosaicing Ayiseyona Into Yokuqala Yokusebenza Kwe-USB Edge Vision
Amakhamera e-USB asebenza njengezingxenyekazi zekhompiyutha eziyisisekelo ekusetshenzisweni kwesimanje kwe-edge vision, asetshenziswa kabanzi emishinini yezimboni, ezinhlelweni zokuzikhokhela ezitolo, ezokuphepha ezihlakaniphile zokujikeleza, ukuzulazula kwamabhothi, kanye nemishini emincane ephathwayo yokuthwebula izithombe zezokwelapha. Aziwa ngokusebenza kalula ngokuplug-and-play, ukuhambisana ngokugcwele nezinhlelo ezahlukene ezifana ne-Windows, i-Linux, nama-edge gateways asebenzisa i-ARM, kanye nokonga izindleko okukalekayo, lawa madivayisi ahola ezimweni ezijwayelekile ze-edge vision. Noma kunjalo, iningi lamamojula amakhamera e-USB asezingeni eliphansi naphakathi linenkinga ebalulekile efihlekile yokusebenza: inqubo endala, engenambuyiselo ephelele yokucubungula imibala (demosaicing).
Cishe wonke ama-ama-sensor we-CMOS we-USBIsici esijwayelekile se-Bayer Color Filter Array (CFA) siyasetshenziswa. Esikhundleni sokuthwebula ulwazi olugcwele lwe-RGB pixel, i-photosite ngayinye irekhoda isiteshi esisodwa sombala obomvu, oluhlaza noma oluhlaza okwesibhakabhaka. I-Demosaicing iyinqubo ebalulekile yokuqala ye-ISP ehlela kabusha izithombe ze-RGB ezigcwele ukuxazulula, eziqondile, kusukela kudatha ye-Bayer enesiteshi esisodwa.
Ukuhlukaniswa kwemibala okungekho ezingeni lokugculisa kungadala izinkinga ezibonakalayo eziningi, okuhlanganisa amaphethini e-moiré anemibala engamanga, imiphumela yezipper emaphethelweni, ukulahlekelwa imininingwane emihle yokuthungwa, ukuvuza kwemibala emingceleni kanye nokwethulwa kwemibala okungathandekile nokungalingani. Ezimweni zokusebenza ezinemba okuphezulu njengokutholwa kwamaphutha ezimbonini, ukuqashelwa kwezinto nge-AI ngesikhathi sangempela, ukuhlonza izinombolo zezimoto kanye nokuqinisekiswa kwe-biometric, lezi ziphazamiso ezincane ezibonakalayo zinciphisa ngqo ukunemba kokucabanga kwamamodeli e-AI, zidale izexwayiso ezingamanga ezivamile, futhi zinciphise ukuzinza kokusebenza kwesikhathi eside kwemishini yokubona esemaphethelweni.
Amanekhamera amaningi e-USB athengwaya eshelufini ancike ku-bilinear interpolation yendabuko ukuze enze i-demosaicing. Yakhelwe ukunciphisa ukusetshenziswa kwamandla kwekhompyutha kanye nokubambezeleka kokudluliswa kolwazi, le algorithm yakudala ifanele kuphela izimo eziyisisekelo zamavidiyo anesisindo esiphansi futhi yehluleka ukuhlangabezana nezidingo eziqinile zekhwalithi yezithombe zezinhlelo zanamuhla zika-2026 ze-edge vision.
