Indlela yokukhetha i-DVR yemoto: ukubuyekezwa namavidiyo
Sekuyisikhathi eside ama-DVR esetshenziswa abashayeli abaningi bezimoto, le divayisi isibe isici esibalulekile ekamelweni. Ngenxa yalokho, ungakwazi ukurekhoda konke okwenzeka kuwe ngenkathi ushayela, futhi uma kwenzeka ingozi yomgwaqo, ungafakazela ubumsulwa bakho. Uma uya kunoma yisiphi isitolo noma uvakashela isitolo se-inthanethi, uzobona izinhlobonhlobo zalawa madivayisi, ahluke komunye nomunye kokubili ngezindleko zawo kanye nezici zawo.
Indlela yokukhetha i-DVR enhle yemoto, yiziphi izici okufanele ngizinake ngokukhethekile? Sesivele simboze lesi sihloko kuwebhusayithi yethu i-Vodi.su, echaza amamodeli adumile wababhalisi ngo-2015.
Empeleni, i-DVR iyikhamera encane efakwe ku-windshield, kodwa eminyakeni yamuva ukusebenza kuye kwanda kakhulu, futhi izinga lokuqopha liye lathuthuka, futhi lokhu akumangazi - bheka ukuthi izingcingo eziphathwayo ziye zavela kude kangakanani eminyakeni eyi-10 - kusukela ku-bulky. ama-monoblocks anama-antenna namandla alinganiselwe , kuma-smartphone azacile kakhulu, okungamakhompyutha amancane agcwele.
Kwenzeka okufanayo nangamarekhodi evidiyo. Nokho, ingabe yonke le misebenzi iyadingeka ekuphileni kwangempela? Ake sicabangele ngokuningiliziwe.
Ikhwalithi yokurekhoda ipharamitha eyinhloko.
Amafomethi alandelayo asetshenziswa njengamanje:
- Amaphikseli e-VGA - 640x480, ifomethi ephelelwe yisikhathi, esithombeni esinjalo ungakwazi ukubona umgwaqo, izimoto ezingaphambili, umgwaqo, kodwa awukwazi ukuhlukanisa noma yini enemininingwane: akunakwenzeka ukunquma izinombolo, ngisho namamodeli wezinye izimoto, ngaphandle kwemibala ihlanekezelwe ngokuphawulekayo;
- I-HD - ukulungiswa okuphezulu kwamaphikseli angu-1280x720, ikhwalithi yokurekhoda ingcono izikhathi eziningana, amavidiyo anjalo angabukwa esikrinini esikhulu, nakuba imininingwane encane - izinombolo zemoto - ingafundwa kuphela ebangeni eliseduze, i-graininess izophinde ibe khona;
- I-Full-HD - amaphikseli angu-1920x1080 - ikhwalithi yesithombe enhle kakhulu, ungabona cishe yonke imininingwane, kuze kufike kuzinombolo zemoto ezingekho kude kakhulu;
- I-Super-HD - 2304 × 1296 - ukulungiswa okungcono kakhulu okwamanje, amavidiyo anjalo angabukwa esikrinini esikhulu se-TV, ikhwalithi izokujabulisa, cishe yonke imininingwane edingekayo izobonakala kuwe: izinombolo, izimpawu zomgwaqo nezimpawu, ubuso babantu nokunye.
Okusho ukuthi, uma ufuna umbhalisi enze umsebenzi wawo oyinhloko kahle, khetha kumafomethi amabili okugcina.
Nokho, ukulungiswa kungenye yezinto ezithinta ikhwalithi yokurekhodwa; ipharamitha efana nesivinini sokurekhoda ibaluleke ngokulinganayo, ikalwa ngamafreyimu ngomzuzwana. Ngokwezindinganiso zanamuhla, isivinini sokurekhoda kufanele sibe okungenani amafreyimu angu-25 ngomzuzwana, kukhona amamodeli athuthuke kakhulu angenza amafreyimu angu-30 ngomzuzwana.
Uma ikhwalithi ephezulu yevidiyo, kuthatha isikhala esiningi kumemori khadi. Kukhona futhi amamodeli lapho ungakhetha khona ijubane lokuqopha ngesandla, isibonelo, uma imemori khadi yakhelwe i-8 noma i-16 GB, kungcono ukukhetha isivinini esiphansi, nakuba iningi labaqopha amavidiyo aphakathi namanani aphezulu angakwazi. amakhadi okusekela ku-36, 64 ngisho naku-128 noma 256 Gigabyte.
Ukuze ufake ulwazi olwengeziwe kumemori khadi, udinga ukukhetha isibhalisi esifanele ngokwendlela yokucindezela ifayela (i-encoder, codec, decoder).
Amafomethi okucindezela ifayela:
- I-MJPEG - ifomethi ephelelwe yisikhathi esekelwe ekucindezelweni kwefreyimu-by-frame, ividiyo enjalo ithatha isikhala esiningi, umsindo ugcinwa ngokuhlukana;
- I-MPEG4 - ukucindezelwa kanyekanye kokusakazwa komsindo nevidiyo, ividiyo ithatha indawo engaphansi izikhathi ezingu-10;
- I-H.264 ifomethi ethuthuke kakhulu, ithatha uhhafu wesikhala kuneyangaphambili, futhi ngaphandle kwalokho, kunombala ongcono nomsindo wokukhiqiza kabusha.
Kunamafomethi afana ne-MOV noma i-AVI, amafayela evidiyo kufolda eqoshwe ngalawa mafomethi amakwe kanje: video.mov noma video.avi. Kukhona namafomethi akhethekile asetshenziswa abakhiqizi ngabanye. Ifomethi ye-VisionDrive, eklanyelwe ukuqopha ividiyo ekuhambeni, iziveza kahle. Ukuze uyidlale, udinga ukulanda uhlelo olukhethekile lwesidlali semidiya ekhompyutheni yakho.
Elinye iphuzu elibalulekile imodi yasebusuku. Empeleni, imodi yasebusuku iyinkinga yanoma yimuphi umbhalisi. Emigwaqweni emikhulu yasemadolobheni ekhanyisiwe, ividiyo iphuma ngisho nangaphezulu noma ngaphansi kwekhwalithi ephezulu, kodwa ngaphandle kwedolobha, lapho imigwaqo eminingi ingakhanyi khona, kunzima kakhulu ukubona noma yini. Ukuze kulungiswe lesi simo, abakhiqizi abaningi bafaka ukukhanya kwe-infrared, kodwa ngokuhlangenwe nakho kwethu siqu sizosho ukuthi akusizi ngalutho.
Nokho, enye ipharamitha ebaluleke kakhulu i-engeli yokubuka. I-engeli ivamise ukukalwa nge-diagonally futhi ingasukela ku-60 kuya ku-170 degrees. Singabiza igebe elilungile - 90-140 degrees. Yile engeli yokubuka ezosivumela ukuthi sicabangele amabhendi angomakhelwane. Uma i-angle incane kakhulu, khona-ke ngeke ubone, isibonelo, izimoto emigwaqweni engumakhelwane, kodwa uma i-angle idlula ama-degree angu-140, isithombe sihlanekezelwa kakhulu ngenxa yomphumela we-fisheye.
Indlela yokukhweza, ikhono lokuguqula ama-degree angu-180 - kukhona ababhalisi abangathunyelwa ngokuphepha ezindaweni ezahlukene ukuze babhale ingxoxo nomhloli wamaphoyisa omgwaqo. Kukhona nalawo afakwe ngokuqinile ku-tripod.
Inzwa yokunyakaza iyisici esiwusizo kakhulu, irekhoda ivuka ngokuzenzakalelayo kumodi yokulala ngokushesha nje lapho noma yikuphi ukunyakaza kubonakala emkhakheni wokubuka.
I-G-Sensor noma inzwa yokushaqeka - ifolda ekhethekile engakhipheki inikezwa kumemori khadi, lapho ividiyo erekhodwe ezimeni eziphuthumayo igcinwa khona. Isibonelo, uma ushaywa ngemuva, noma uphoqeleke ukuthi ubhuleke kanzima, ividiyo izogcinwa kule folda futhi ngeke isuswe ngesikhathi sokuqoshwa kweluphu.
I-GPS iyisengezo esiwusizo kakhulu. Ividiyo irekhoda isivinini sokunyakaza kanye nedethi yamanje. Futhi-ke, lapho ubuka ividiyo kukhompuyutha, ungayixhumanisa ne-Google Maps, futhi isivinini sangempela sokunyakaza sizoboniswa engxenyeni ngayinye.
Naka futhi ubukhulu besibonisi, umthamo webhethri, ukusebenza kwesithombe, ibhalansi emhlophe, isihlungi (ukuhlola imisebe engadingekile).
Irekhoda yevidiyo engaphezulu noma engaphansi evamile izobiza okungenani ama-ruble ayizinkulungwane ezi-4.
Iyalayisha...
