Kwadalwa ngo 2025.12.01
Izinhlelo zokubheka ithrafikhi zibhekene nomsebenzi oqhubekayo wokulwa nezinye zezinto ezingalindelekile zemvelo: ukukhanya. Kusukela ekukhanyeni okukhulu kwelanga eliphakeme phakathi nosuku kuya ekushintsheni okungazelelwe phakathi kokukhanya kwe-tunnel nokukhanya kwelanga, amakhamera ajwayelekile abhekana nobunzima bokuthola ividiyo ecacile ezimeni ezine-contrast ephezulu. Lokhu akusikho nje udaba lwekhwalithi—kuwudaba olubalulekile ngokuphepha. Amathikithi okushayela angacacile, abantu abangenakubonwa, kanye neziphazamiso zethrafikhi eziphuthelwe zingaba nemiphumela eguqula impilo. NgenaWide Dynamic Range (WDR) camera modules: ukuphumelela kwezobuchwepheshe okuphinde kuchaze ukuthi yini enokwenzeka ekuhloleni traffic.
Ukuqonda Isayensi Ngemuva kwe-WDR: Ngaphezu Kobuchwepheshe BeKhamera Obuyisisekelo
Ngokuyinhloko, ubuchwepheshe be-WDR buxazulula umkhawulo oyisisekelo wamakhamera ajwayelekile: ukungakwazi kwabo ukuphatha umehluko omkhulu wokukhanya emfanekisweni owodwa. Ikhamera ejwayelekile ithatha izithombe ezinobubanzi obuphakeme be-60-80dB, kanti izimo zomgwaqo zangempela zivame ukudlula i-120dB—cabanga ukukhanya kwelanga okuqondile okukhanya phezu kwepavement ethambile njengoba abantu behlezi ezindaweni ezimnyama zokuhamba. I-WDR ixazulula lokhu ngokuthatha izithombe eziningi ngesikhathi esisodwa bese ihlanganisa lezi zithombe zibe emfanekisweni owodwa ophakathi.
Izobuchwepheshe ezimbili eziyisisekelo ziqhuba amamojula wekhamera ye-WDR yesimanje ezinhlelweni zokuhamba:
• I-CCD + DSP Ukuhlanganiswa: Isebenzisa ama-sensor e-CCD anesivinini esiphindwe kabili ukuze ithathe izithombe ezisheshayo nez slow, bese isebenzisa ama-DSP chips ukuhlanganisa izithombe. Le ndlela iletha imiphumela ethembekile ezimeni ezifana nezikhungo zokukhokha, lapho ukukhanya kwezinhlamvu zezimoto kuhlangana nokukhanya okuphakanyisiwe.
• Izinhlelo ze-CMOS + DPS: Tem representa ukuthuthuka okulandelayo nge-Digital Pixel System (DPS) technology. I-pixel ngayinye icubungula ukukhanya ngokuzimela, ifinyelela kumazinga adlulele ku-120dB—kuphakeme kakhulu kunezikhono ze-CCD ezijwayelekile. Le ndlela ikhululekile ezindaweni zokuhamba ezisheshayo, inikeza ukunemba kwemibala okuphezulu nokusebenza kahle ezimeni zokukhanya okuphansi.
Ubuhlakani be-WDR abukhona nje kuphela ukukhuthazwa kwemakethe; bukhona obala. Izindinganiso zezimboni ezifana ne-GA/T 1127—2013 zihlola ukusebenza kwe-WDR ngama-metric ayisishiyagalolunye abalulekile, kuhlanganise nokuxazulula kwe-grayscale, ukuqhathaniswa kwemikhawulo, kanye nobudlelwano phakathi kwesignali noshintsho. Ekubhekeni traffic, lokhu kuhunyushwa kube ukuthuthuka okungalinganiswa emisebenzini ebalulekile efana nokuhlonza amaphuzu ezinhlamvu (LPR) kanye nokuhlukaniswa kwemoto.
Izicelo Zangempela: Lapho i-WDR Yenza Umehluko
Ukuhlola ukuhamba kwemoto kudinga ukuhamba, futhi ama-module we-WDR camera ahlinzeka ngezimo ezine ezinamandla:
1. Imali Yokudlula Emgwaqweni Nokuphathwa Kwezithuthi
Izikhungo zokukhokha ziwumoya ophakathi kwezinkinga zokukhanyisa: ukukhanya kwelanga okuqondile, izindawo ezikhanyayo, kanye nezibani ezisondela. Amakhamera ajwayelekile avame ukukhiqiza izindawo zezulu ezikhanyayo kakhulu noma izikhala zemoto ezikhanyayo kancane, okuphazamisa kokubili ukusebenza kahle kokuhweba nokuphepha.
