Amakhamera angemuva angemuva nemigqa yokupaka. Ungakhetha kanjani ikhamera yokupaka?

Abashayeli bezimoto sekuyisikhathi eside benethuba lokusiza imisebenzi yabo emgwaqeni ngosizo lwabaxhasi be-electronics. Ukupaka okuphephile futhi okulula namhlanje, kunamaqembu amabili alawo madivayisi - i-parktronics namakhamera asakaza isithombe sembukiso yangemuva. Futhi uma isigaba sokuqala sabasizi sifaneleka kakhulu kubaqalayo, khona-ke ngokushesha noma kamuva kuzoba abashayeli abanolwazi, ukuqonda ukubaluleka kwesisombululo esinjalo kokubili njengendlela yokukhuphuka kokuphepha, futhi njengendlela yokugcina isikhathi. Ngokuyinhloko, ama-cameras angemuva anemigqa yokupaka ikuvumela ukuba ulawule ukuhamba kwemoto ngaphandle kokuphazamiseka ngaphandle kokungqubuzana nezinye izinto.

Iyini isici somsebenzi wokupaka yokupaka?

Amamodeli wokuqala futhi alula kakhulu ekubukeni kwamakhamera afakwe abaqaphi abangenayo le nketho. Bawuhlobo oluhlanzekile lwemvelo oludlulisela isithombe, okuvumela ukuqondiswa umshayeli ezimweni zesimo sangempela. Amamodeli wanamuhla, ngisho nasemaphaketheni ajwayelekile, anikezwa ukuthi kungenzeka ukukhombisa imigqa yokupaka. Lesi yisiqeshana semifanekiso esibukweni esikrinini, esibonisa imingcele ongayiqhuba ngayo ngokuphepha ngokuphepha. Isimiso sokugqoka kwabo sincike ekusebenzeni kwesofthiwe yekhamera yokubuka ngemuva. Imigqa yokupaka ezithombeni zakamuva ihlelwe ngokuya esikhundleni sekholomu yokuqondisa futhi, ngokufanayo, ukujikelezwa kwamavili. Lesi sixazululo senza izenzo zomshayeli zilula, kodwa kufanele sicabange ukuthi iphutha elincane ekugqeni kwemigqa lingabangela ukushayisana. Ngakho-ke, akudingekile ukuba uthembele ngokuphelele kubo - uma uhlaziya ukunyakaza, umuntu kufanele futhi acabangele isimo sangempela esidluliselwa esibukweni.

Ukhetha ukuthini ikhamera?

Amakhamera ngokwawo ahluke ngokuyinhloko ekwakheni. Imodeli ye-Mortise inhle kakhulu ekusebenzisaneni kwazo. Ziyakwazi ukuhlanganiswa emzimbeni kwanoma imuphi imoto, kodwa kuzodingeka uqhube imbobo ekhethekile yokufaka. Mayelana nokufakwa, inketho engcono kakhulu ikhamera ephezulu. Akudingi ukuphazanyiswa okulimalayo kulesi simo futhi kungasungulwa nge-bolt ephelele emgqonyeni wephakethi yelayisense. Kodwa lapha kuyadingeka ukhethe imodeli evumelana nomklamo othize wephoyinti lokufaka. Izinketho eziningi zokuqapha zihlinzekwa ngamakhamera angemuva ngemigqa yokupaka kubakaki. Isici sabo esihlukile siyakwazi ukuguqula, ukushintsha kanye nokubukeka kombono. Zifakwe ku-cabin - isibonelo, ewindini elingemuva.

Indlela yokusebenza

Ngenkathi yokusebenza, imingcele emibili eyinhloko izobaluleka - uhlobo lomthamo kanye nesinqumo. Bazonquma ukuthi "isithombe" esiphatheleneyo sizophakama kanjani. Ngokuqondene ne-matrix, namuhla kunamakhamera anamamojula amabili. Okukhethwa kukho kuqala yi-CCD system, inzuzo enkulu eyandisa ukuzwela. Lokhu kungenxa yokupaka kusihlwa - lokhu kuyindlela efaneleka kakhulu. Uhlelo lwe-CMOS lunenzuzo eyodwa kuphela yokusebenza, okuyinto ijubane lokucubungula idatha. Ama-cameras anemuva afaka imigqa yokupaka ne-monitor angakwazi ukuhlinzeka ngemigudu emihle yokulandelana kwevidyo, kodwa ukucaca kwabo kuyoba kude nokungenasici. Kukhona neze okukhethwa kukho ngokukhetha. Isakhiwo esimisiwe ngu-628h582 (0.3 MP) futhi kwanele ukwanelisa imisebenzi yomsizi wokupaka.

Ukukhethwa ngombono wokubuka

Ububanzi bamazinga obonakalayo bubanzi kakhulu, kodwa inamba yabo ayiqiniseki njalo ikhwalithi yesithombe esihle. Eqinisweni, ukukhetha kungaba phakathi kuka-120 no-170 degrees. Izinga liyi-angle yama-degrees angu-120. Ekuhumusheni okunjalo, isithombe asikhathalwanga futhi esimweni sokuqapha sizobonakala njengeningiliziwe. Noma kunjalo, ama-170-degree angemuva-abheka amakhamera anemigqa yokupaka asetshenziselwa ukukhangisa ngabakhiqizi bamamodeli we-premium. Inzuzo yabo iyoba yindawo enkulu yokusebenza "endaweni" yokusebenza, ngakho-ke akufanele ushiye lesi sinqumo ngokushesha. Ngaphambi kokukhetha, kufanele uqale ucabange ukuthi idivayisi izofakwa kuphi nokuthi ngabe izokwazi yini ukuhlinzeka ngokwanele ngezinga elincane. Uma kungenjalo, ngenxa yokubukeza, kuzodingeka unikele ngokucacile, futhi kwezinye izimo ukuzwela.

Ukukhethwa ngendlela yokudluliselwa kwesignali

Kulesi sigaba sizoxoxa ngendlela ikhamera nokuqapha ngayo. Ukuxhumeka okujwayelekile kufaka ukubeka ucingo cishe ngaphakathi kwendawo yonke yangaphakathi ngendawo ephethe imithwalo. Ngokusobala, ukusebenzisa ikhebula levidiyo kuzodla isikhathi futhi kuyabiza. Ngakho-ke, ama-kits zanamuhla adluliselwa kuhlobo lokuxhumana olungenantambo. Amakhamera angemuva angemuva anemigqa yokupaka asebenzisana nomqapha ngamamojula omsakazo owakhiwe. Ububanzi bufinyelela ku-15 m, ngakho-ke ngeke kube nezinkinga zokuxhumana. Noma kunjalo, amasistimu angenazintambo anezinselele ezimbili: okokuqala, izindleko eziphezulu, futhi okwesibili, ukuphazamiseka komuntu wesithathu kungakhubaza okwesikhashana idivayisi noma ukuhlanekezela "isithombe".

Izidingo ezengeziwe

Ngeke kube yinto engafanele ukuba nomsakazo wokubukeka ekubonisweni. Ngesikhathi esifanayo kusihlwa noma ebusuku, izithombe esikrinini kungenzeka ukuthi azimele, nokukhanya kwe-infrared kuzofaka ukucaca "esithombeni". Futhi, imishini yangaphandle kufanele ivikeleke kahle ekuthunjweni nasekuthunjweni. Amakhamera angemuva amaningi okubukwayo anemigqa yokupaka enokusekelwa kokubonisa okuningi amathuba okuxhumana ne-DVRs ne-TV tuners. Ngaphezu kwalokho, i-autonavigator enevidiyo ye-AV format ye-AV nayo ixhunyiwe. Kulesi simo, ideshibhodi ingasuswa ekukholeni kwezinsimbi zomuntu ngamunye ngezinketho ezingenhla.

Ukubuyekeza kwabakhiqizi

Emakethe kunamamodeli kubo bobabili abakhiqizi abakhulu bemishini yezimoto, nakubo abakhiqizi abathandwayo bama-electronics. Ngokusho kwabathengi ngokwabo, amafomu kufanele anakekelwe kumaFree AutoExpert, Proline, Blackview ne-Spark. Isibonelo, amakhamera avela ku-AutoExpert ayalwa njengokwethenjelwa, ukuqina kwecala nokuzinza kokudluliswa kwesignali. Lesi yisisombululo esivamile futhi esingabizi, nakuba singabonisi intuthuko entsha yezobuchwepheshe. Ngakolunye uhlangothi, izinzuzo zomsebenzi zanamuhla zidunyiswa abasebenzisi beMikhiqizo yeProline ne-Blackview - lezi zinguchwepheshe obuphezulu, kodwa ama-cameras anemali engemuva ehamba phambili ephethe imigqa yokupaka. Ukubuyekeza kubonisa kokubili izinzuzo ze-video matrix kulawo onobuhle, nesithombe esicacile - ngisho nasebumnyameni. Isibonelo, imodeli esuka ku-UC-77 Blackview enezi-16 zama LED yiyakwazi ukunikeza ukubonakala okuhle endaweni yokufakaza ngisho nasebusuku.

Isiphetho

Intuthuko emkhakheni wezimoto zezimoto ngonyaka iqala izixazululo ezintsha zobuchwepheshe. Ukwandiswa kokusebenza, okuyiqiniso, kukhonjiswe ngamanani, kodwa kanye nabo ikhwalithi yomkhiqizo nayo iyanda. Ukwakhiwa kobuciko, izinketho ezintsha kanye ne-ergonomic ezithuthukisiwe yizo ezibonisa amamera amakhamera angemuva anemigqa yokupaka. Ungakhetha kanjani ikhi efanelekayo? Ngaphezu kwemigomo engenhla, ungakhohlwa ngezimfanelo zambili. Isibonelo, ochwepheshe batusa ukucabanga ngokusebenzisa amathuba okukhulumisana kwesikhathi esizayo nedivayisi nezinye izingxenye zemishini ejwayelekile. Unganaki ukuxhumana kwe-stylistic kokuboniswa ngaphakathi kwe-salon. Abakhiqizi bavame ukuthuthukisa nokuklama izinzuzo zamakhamera nokubonisa ngokukhethekile, ngakho-ke kule parametri kukhona okumele ukhethe.
