Iyini ikhamera engaphambili yemoto
Ikhamera engaphambili yemoto (ikhamera yokubuka ngaphambili) iyikhamera efakwe ngaphambili kwemoto. Isetshenziswa kakhulu ukuqapha isimo esiphambi komgwaqo nokusiza imoto ukuthi yenze imisebenzi ehlukahlukene ehlakaniphile.
Incazelo kanye nomsebenzi
Ikhamera yokubuka ngaphambili ingenye yezingxenye eziyinhloko zohlelo lwe-ADAS (Advanced Driver Assistance System), olusetshenziswa kakhulu ukuqapha isimo esingaphambi komgwaqo nokuhlonza umgwaqo, izimoto kanye nabahamba ngezinyawo abangaphambili. Ngokusebenzisa izinzwa zezithombe kanye nokucubungula i-DSP (digital signal processor), ikhamera yokubuka ngaphambili inikeza ukucutshungulwa kwesithombe ngesikhathi sangempela ukusiza ukuqalisa imisebenzi efana nokuxwayisa ngokushayisana kwemoto (i-FCW), isixwayiso sokuhamba komzila (i-LDW) kanye nokulawula ukuhamba ngesikebhe okuguqukayo (i-ACC).
Indawo yokufaka kanye nohlobo
Ikhamera yokubuka ngaphambili ivame ukufakwa esibukweni sangaphambili noma esibukweni sangemuva esingaphakathi futhi ine-engeli yokubuka engama-degrees angaba ngu-45, ehlanganisa ibanga elingamamitha angu-70-250 phambi kwemoto. Ngokwezidingo ezahlukene, imoto ingaba namakhamera amaningi okubuka ngaphambili, isibonelo, uhlelo lwe-Tesla Autopilot luhlonyiswe ngensimu encane yokubuka, insimu enkulu yokubuka kanye namakhamera amathathu okubuka abanzi, asetshenziselwa ukuqapha isimo sethrafikhi kanye nethrafikhi ebangeni elihlukile .
Izici zobuchwepheshe kanye nomkhuba wentuthuko yesikhathi esizayo
Ubuchwepheshe bekhamera yokubuka ngaphambili buyinkimbinkimbi, okudingeka ibambisane nenzwa yesithombe kanye ne-dual-core MCU (microcontroller) ukuze kuqedwe ukucutshungulwa kwezithombe okuyinkimbinkimbi. Izitayela zobuchwepheshe zesikhathi esizayo zifaka phakathi ukwethulwa kwamakhamera anembe kakhulu kanye nokuhlanganiswa kwezinzwa eziningi ukuthuthukisa ukuthembeka nokusebenza kwezinhlelo zokuzwa. Ngokuthuthuka kobuchwepheshe be-AI, ikhamera yokubuka ngaphambili izoba nobuhlakani obuningi, ikwazi ukubona nokusingatha izimo zethrafikhi eziyinkimbinkimbi, futhi ithuthukise ukuphepha nokuhlakanipha kokushayela .
Imisebenzi eyinhloko yamakhamera angaphambili ezimoto ihlanganisa ukuthuthukisa ukuphepha kokushayela kanye nokulula.
Indima eyinhloko
Kuthuthukisa ukuphepha kokushayela: Ngokuqapha umgwaqo, izimoto kanye nabahamba ngezinyawo phambi kwemoto ngesikhathi sangempela, amakhamera angaphambili asiza abashayeli ukuthi babone izingozi ezingaba khona, njengabahamba ngezinyawo, izilwane noma ezinye izimoto, kusenesikhathi, ngaleyo ndlela bagweme ukushayisana noma banciphise amathuba ezingozi. Ngaphezu kwalokho, ikhamera engaphambili ingaphinde inikeze izithombe ezinyakazayo ezingama-degree angu-360 ukusiza umshayeli ukuthi aqonde indawo ezungezile yemoto, ikakhulukazi lapho epaka futhi ebuyela emuva, ukuze agweme ngempumelelo ingozi yezindawo ezingaboni.
Ukushayela okusizwayo : Amanye amakhamera angaphambili athuthukile anesexwayiso sokuhamba komzila, isexwayiso sokushayisana kwangaphambili kanye neminye imisebenzi, enganikeza amathiphu okuphepha ngesikhathi sangempela ngesikhathi sokushayela futhi inciphise izingozi zokushayela. Isibonelo, umsebenzi wesixwayiso sokushayisana kwangaphambili ungabona imoto ephambi kwawo ngezithombe, futhi ukhiphe i-alamu ngesikhathi lapho kunengozi yokushayisana. Umsebenzi wesixwayiso sokuhamba komzila ungaxwayisa umshayeli lapho imoto iphambuka emzileni ukuze kugwenywe izingozi.
Thuthukisa ukulula kokupaka: Ikhamera engaphambili ingasiza abashayeli ukuthi bahlulele ngokunembile ibanga phakathi kwemoto nezithiyo, ikakhulukazi ezindaweni zokupaka ezinabantu abaningi noma emigwaqweni emincane, indima yekhamera engaphambili isobala kakhulu. Ngokusebenzisa isibonisi esisebhodini ukubuka isimo esizungeze imoto ngesikhathi sangempela, umshayeli angaqonda kangcono isimo sokushayela semoto futhi athuthukise ukulula kokupaka nokushayela.
Isimo sesicelo esithile
Ukupaka nokubuyela emuva: Ikhamera engaphambili inikeza izithombe zevidiyo zesikhathi sangempela ngesikhathi sokupaka nokubuyela emuva ukusiza abashayeli ukuba bagweme izindawo ezingabonakali futhi baqinisekise ukusebenza okuphephile.
Isexwayiso sokuhamba komzila: Ngokubheka ukuthi imoto iyaphambuka yini emzileni, ikhamera engaphambili ingaxwayisa umshayeli ngesikhathi ukuze agweme izingozi.
Isexwayiso sokushayisana kwangaphambili: Ngokubona izimoto kanye nabahamba ngezinyawo phambi kwabo, amakhamera angaphambili angakhipha izexwayiso uma kunengozi yokushayisana futhi axwayise abashayeli ukuthi bathathe isinyathelo.
Ukulawula ukuhamba ngesikebhe okuguquguqukayo: Ikhamera engaphambili ingakwazi ukubona ithrafikhi engaphambili futhi isize imoto ukuthi igcine ibanga eliphephile lokulawula ukuhamba ngesikebhe okuguquguqukayo.
Izici zobuchwepheshe kanye nomkhuba wokuthuthukiswa
Ikhamera engaphambili ivame ukufakwa esibukweni sangemuva noma esibukweni sangemuva esingaphakathi, kanti i-engela yokubuka ingama-45°, engakwazi ukuqapha kahle umgwaqo, izimoto kanye nabahamba ngezinyawo abangaphambili. Ngokuthuthuka kobuchwepheshe, ikhamera engaphambili izoba nobuhlakani obukhulu futhi ikwazi ukubona nokusingatha izimo zethrafikhi eziyinkimbinkimbi ngokusebenzisa ama-algorithms okufunda okujulile, ithuthukise ukuphepha kanye nobuhlakani bokushayela.
