Iyini ikhamera yangaphambili yemoto
Ikhamera yangaphambili yemoto (ikhamera yokubuka ngaphambili) iyikhamera efakwe ngaphambili emotweni. Ngokuyinhloko isetshenziselwa ukuqapha isimo esiphambi komgwaqo futhi isize imoto ukuthi ibone imisebenzi ehlukahlukene ehlakaniphile. .
Incazelo kanye nomsebenzi
Ikhamera yokubuka ngaphambili ingenye yezingxenye ezibalulekile zesistimu ye-ADAS (Advanced Driver Assistance System), esetshenziswa kakhulu ukuqapha isimo ngaphambi komgwaqo futhi ihlonze umgwaqo, izimoto nabahamba ngezinyawo ngaphambili. Ngokusebenzisa izinzwa zesithombe nokucubungula kwe-DSP (iphrosesa yesignali yedijithali), ikhamera yokubuka yangaphambili ihlinzeka ngokucubungula isithombe sesikhathi sangempela ukuze isize ukusebenzisa imisebenzi efana nesexwayiso sokungqubuzana okuya phambili (FCW), isixwayiso sokuhamba komzila (LDW) kanye nokulawulwa kohambo oluguquguqukayo (ACC) .
Indawo yokufaka kanye nohlobo
Ikhamera yokubuka ngaphambili ivamise ukufakwa kuwindshield noma ngaphakathi kwesibuko esingemuva futhi ine-Angle yokubuka elinganiselwa ku-45 degrees, ehlanganisa ibanga elingamamitha angu-70-250 phambi kwemoto. Ngokwezidingo ezahlukene, imoto ingase ifakwe amakhamera amaningi okubuka ngaphambili, isibonelo, uhlelo lwe-Tesla Autopilot lufakwe insimu encane yokubuka, inkambu enkulu yokubuka kanye nenkundla ebanzi yokubuka amakhamera amathathu, ngokulandelana asetshenziselwa ukuqapha okuhlosiwe kanye nesimo sethrafikhi emabangeni ahlukene.
Izici zobuchwepheshe kanye nentuthuko yesikhathi esizayo
Ubuchwepheshe bekhamera yokubuka yangaphambili buyinkimbinkimbi, edinga ukubambisana nenzwa yesithombe kanye ne-dual-core MCU (microcontroller) ukuze kuqedelwe ukucubungula isithombe esiyinkimbinkimbi. Amathrendi obuchwepheshe besikhathi esizayo ahlanganisa ukwethulwa kwamakhamera anemba okuphezulu kanye nokuhlanganiswa kwezinzwa eziningi ukuze kuthuthukiswe ukwethembeka nokusebenza kwamasistimu enzwa. Ngokuthuthuka kobuchwepheshe be-AI, ikhamera yokubuka yangaphambili izohlakanipha kakhulu, ikwazi ukubona nokusingatha izimo zethrafikhi eziyinkimbinkimbi, futhi ithuthukise ukuphepha nobuhlakani bokushayela .
Imisebenzi esemqoka yamakhamera angaphambili emoto ihlanganisa ukwenza ngcono ukuphepha kokushayela kanye nokwenza lula. .
Indima eyinhloko
Ithuthukisa ukuphepha kokushayela : Ngokuqapha umgwaqo, izimoto nabahamba ngezinyawo phambi kwemoto ngesikhathi sangempela, amakhamera angaphambili asiza abashayeli ukuthi babone izingozi ezingaba khona, njengabahamba ngezinyawo, izilwane noma ezinye izimoto, kusengaphambili, ngaleyo ndlela bagweme ukushayisana noma ukunciphisa amathuba ezingozi. Ngaphezu kwalokho, ikhamera yangaphambili ingase futhi inikeze izithombe zepanoramic ezingu-360-degree ukusiza umshayeli aqonde indawo ezungezile yemoto, ikakhulukazi lapho upaka futhi ehlehla, ukuze agweme ngempumelelo ubungozi bezindawo ezingaboni emehlweni.
ukushayela okusizwayo : Amanye amakhamera angaphambili athuthukile anesexwayiso sokusuka emzileni, isexwayiso sokushayisana kwangaphambili neminye imisebenzi, enganikeza amathiphu okuphepha ngesikhathi sangempela phakathi nokushayela futhi anciphise izingozi zokushayela. Isibonelo, isixwayiso sokushayisana phambili singabona imoto ephambi kwayo ngezithombe, futhi sikhiphe i-alamu ngesikhathi lapho kunobungozi bokushayisana. Umsebenzi wokuxwayisa ngokuhamba komzila ungaxwayisa umshayeli lapho imoto ichezuka emzileni ukugwema izingozi.
Thuthukisa ukwenza kube lula ukupaka : Ikhamera yangaphambili ingasiza abashayeli bahlulele ngokunembe kakhudlwana ibanga eliphakathi kwemoto nezithiyo, ikakhulukazi ezindaweni zokupaka eziminyene noma emigwaqweni emincane, indima yekhamera yangaphambili isobala kakhulu. Ngesibonisi esisebhodini ukuze ubuke isimo esizungeze imoto ngesikhathi sangempela, umshayeli angakwazi ukuqonda kangcono isimo sokushayela kwemoto futhi athuthukise ukunethezeka kokupaka nokushayela.
Isimo sohlelo lokusebenza oluthile
Ukupaka nokubuyisela emuva : Ikhamera yangaphambili inikeza izithombe zevidiyo zesikhathi sangempela ngesikhathi sokupaka nokuhlehla ukusiza abashayeli bagweme izindawo ezingaboni futhi baqinisekise ukusebenza okuphephile.
Lane Isexwayiso sokusuka : Ngokuqaphela ukuthi imoto iyachezuka yini emzileni, ikhamera yangaphambili ingaxwayisa umshayeli kusenesikhathi ukuze agweme izingozi.
Isexwayiso sokushayisana phambili : Ngokuhlonza izimoto nabahamba ngezinyawo phambi kwabo, amakhamera angaphambili angakhipha izexwayiso uma kunobungozi bokushayisana futhi axwayise abashayeli ukuthi bathathe isinyathelo.
i-adaptive cruise control : Ikhamera yangaphambili ingakwazi ukubona ithrafikhi engaphambili futhi isize imoto igcine ibanga eliphephile ukuze i-adaptive cruise control.
Izici zobuchwepheshe kanye nentuthuko mkhuba
Ikhamera yangaphambili ivamise ukufakwa esibukweni somoya noma ngaphakathi kwesibuko esingemuva, kanti i-Angle yokubuka icishe ibe ngu-45°, ekwazi ukuqapha kahle umgwaqo, izimoto nabahamba ngezinyawo ngaphambili. Ngokuthuthuka kobuchwepheshe, ikhamera yangaphambili izohlakanipha kakhulu futhi ikwazi ukubona nokusingatha izimo zethrafikhi eziyinkimbinkimbi ngokusebenzisa ama-algorithms okufunda okujulile, ukuthuthukisa ukuphepha nobuhlakani bokushayela.
