Ikhodi enezinhlangothi ezimbili" target="_blank">Ikhodi enezinhlangothi ezimbili ibizwa nangokuthi Ikhodi ye-QR, futhi igama eligcwele le-QR elithi Quick Response. Iyindlela edume kakhulu yokubhala amakhodi kumadivayisi eselula eminyakeni yamuva. Ingakwazi ukugcina okwengeziwe. Ulwazi lungaphinda lumele izinhlobo eziningi zedatha.
Ibha yebhakhodi enezinhlangothi ezimbili/ibhakhodi enezinhlangothi ezimbili (ibhakhodi enezinhlangothi ezimbili) irekhoda ulwazi lophawu lwedatha olunesibalo esithile sejometri esatshalaliswa endizeni (indlela enezinhlangothi ezimbili) ngokwemithetho ethile; Kusetshenziswa imiqondo ka-"0" kanye "1" bit streams akha isisekelo esinengqondo sekhompuyutha, kusetshenziswa izimo zejiyomethri eziningana ezihambisana kanambambili ukumela umbhalo nolwazi lwezinombolo, ukufunda okuzenzakalelayo ngemishini yokufaka isithombe noma okokusebenza okuthwebula ugesi ukuze kufezwe ukucubungula okuzenzakalelayo. yolwazi: inezici ezivamile zobuchwepheshe bebhakhodi: isistimu yekhodi ngayinye inesethi yayo yezinhlamvu ezithile; uhlamvu ngalunye luthatha ububanzi obuthile; inomsebenzi othile wokuqinisekisa, njll. Ngesikhathi esifanayo, iphinde ibe nomsebenzi wokuhlonza okuzenzakalelayo kolwazi emigqeni ehlukene, kanye nokucutshungulwa kokujikeleza kwesithombe nokushintsha amaphuzu.
Izici
1. Ukubhala amakhodi okuminyana kakhulu, umthamo omkhulu wolwazi: ungamukela osonhlamvukazi abangu-1850 noma izinombolo ezingu-2710 noma 1108 byte, noma izinhlamvu zesiShayina ezingaphezu kuka-500, okuphindwe izikhathi eziningi ngaphezu komthamo wolwazi webhakhodi evamile.
2. Uhlu olubanzi lwamakhodi: ibhakhodi ingakwazi ukufaka ikhodi ezithombeni, imisindo, izinhlamvu, amasiginesha, izigxivizo zeminwe nolunye ulwazi olufakwe kwidijithali, futhi ikuveze ngamabhakhodi; ingamela izilimi eziningi; ingamela idatha yesithombe.
3. Ukubekezelela amaphutha okuqinile nomsebenzi wokulungisa amaphutha: lokhu kwenza ibhakhodi enezinhlangothi ezimbili ifundeke kahle uma ilimele kancane ngenxa yokubhobozwa, ukungcoliswa, njll., futhi ulwazi lusatholakala lapho indawo eyonakele ifinyelela ku-50%.
4. Ukuthembeka okuphezulu kokuqopha ikhodi: Kuphansi kakhulu kunezinga lephutha lokuqoshwa kwebhakhodi elivamile elingu-2/1000000, futhi izinga lephutha elincane alidluli ku-1/10000000.
5. Izindlela zokubhala ngemfihlo zingethulwa: ukugcinwa kuyimfihlo kanye nokulwa nokukhwabanisa kuhle.
6. Izindleko eziphansi, kulula ukwenza, futhi zihlala isikhathi eside.
7. Ukuma, ubukhulu kanye nesilinganiso sezimpawu zebhakhodi kungashintshwa.
8. Amabhakhodi e-2D angafundwa kusetshenziswa i-laser noma izifundi ze-CCD.
