Postopek je hitrej\u0161i, kot se zdi, in razumevanje vam pomaga ustvariti kode, ki se vsaki\u010d zanesljivo skenirajo.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Kaj je koda QR<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Koda QR je dvodimenzionalna matrika \u010drno-belih kvadratov, razporejenih v edinstvenem vzorcu. Za razliko od tradicionalne \u010drtne kode \u2013 ki kodira podatke v eni sami vodoravni \u010drti razli\u010dnih \u0161irin \u010drt \u2013 koda QR shranjuje informacije tako vodoravno kot navpi\u010dno. To ji daje veliko ve\u010djo podatkovno zmogljivost in jo omogo\u010da branje iz ve\u010d smeri.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vsaka koda QR je sestavljena iz ve\u010d funkcionalnih regij:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Iskalni vzorci<\/strong> \u2013 trije veliki kvadrati v vogalih, ki skenerju pomagajo locirati kodo, dolo\u010diti njeno orientacijo in najti njene robove, tudi ko je koda nagnjena<\/li>\n<li><strong>\u010casovni vzorci<\/strong> \u2013 izmeni\u010dni \u010drno-beli moduli, ki potekajo med iskalnimi vzorci in dolo\u010dajo strukturo mre\u017ee ter pomagajo skenerju pravilno dolo\u010diti velikost vsakega modula<\/li>\n<li><strong>Tiha cona<\/strong> \u2013 prazna bela obroba okoli kode, \u0161iroka vsaj \u0161tiri module, ki jo lo\u010duje od okoli\u0161ke grafike, tako da lahko skener zazna njene meje<\/li>\n<li><strong>Informacije o formatu<\/strong> \u2013 namensko obmo\u010dje blizu iskalnih vzorcev, ki shranjuje raven popravljanja napak in vzorec maskiranja, tako da skener natan\u010dno ve, kako interpretirati podatke<\/li>\n<li><strong>Podatkovni moduli<\/strong> \u2013 posamezni \u010drno-beli kvadrati, kjer se nahaja dejanska kodirana vsebina, prebrani kot binarne enice (\u010drne) in ni\u010dle (bele)<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Podatki v teh modulih so lahko kodirani v ve\u010d na\u010dinih: samo \u0161tevil\u010dno, alfanumeri\u010dno, 8-bitni binarni bajti ali Kanji. Koda QR razli\u010dice 1 je 21\u00d721 modulov; koda razli\u010dice 40 se raz\u0161iri na 177\u00d7177 in lahko shrani do 7.089 \u0161tevil\u010dnih znakov, 4.296 alfanumeri\u010dnih znakov ali 2.953 bajtov binarnih podatkov.

To je surov vhod \u2013 fotografija \u010drno-belega vzorca. Ve\u010dina sodobnih kamer pametnih telefonov to zmore brez namenske aplikacije za skeniranje. \u010ce \u017eelite razumeti celoten nabor na\u010dinov za spro\u017eitev skeniranja na razli\u010dnih napravah, je <a href=\"https:\/\/pageloot.com\/sl\/how-to\/scan-qr-codes\/\">vodnik za skeniranje QR kod<\/a> podrobno pokriva delovne tokove za iPhone, Android, tablice in namizne ra\u010dunalnike.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Korak 2: Zaznavanje vzorca<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Programska oprema skenerja uporablja prepoznavanje vzorcev za lociranje QR kode znotraj slike. I\u0161\u010de tri iskalne vzorce v vogalih. Ko so najdeni, skener dolo\u010di:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Kje je koda postavljena v okvirju<\/li>\n<li>V katero smer je usmerjena (tudi \u010de je zasukana ali rahlo po\u0161evna)<\/li>\n<li>Kje so robovi kode<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Ta korak je razlog, zakaj so QR kode berljive pod kotom \u2013 iskalni vzorci dajejo algoritmu dovolj geometrije za popravljanje popa\u010denja.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Korak 3: Vzor\u010denje mre\u017ee in ekstrakcija podatkov<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Ko sta polo\u017eaj in usmerjenost kode dolo\u010dena, skener prebere \u010dasovne vzorce in poravnalne oznake, da razume strukturo mre\u017ee. Nato vzor\u010di vsak modul po dolo\u010deni cikcak poti \u2013 od desne proti levi, nato navzgor in navzdol \u2013 za\u010den\u0161i z znanim polo\u017eajem in se premika skozi vsak podatkovni modul, dokler ni dose\u017een kon\u010dni indikator.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Ko prehaja to pot, skener prebere:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>A <strong>indikator na\u010dina<\/strong> (\u0161tiri module), ki dolo\u010da vrsto kodiranja \u2013 \u0161tevil\u010dno, alfanumeri\u010dno, bajtno ali kand\u017ei<\/li>\n<li>A <strong>indikator \u0161tevila znakov<\/strong> ki navaja, koliko znakov je kodiranih<\/li>\n<li>Preostale <strong>podatkovne kodne besede<\/strong> do konca podatkovnega toka<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Korak 4: Popravljanje napak<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Po branju podatkovnih modulov skener obdela kodne besede za popravljanje napak. QR kode uporabljajo <strong>Reed\u2013Solomonovo popravljanje napak<\/strong>, ki vdeluje odve\u010dne podatke, ki omogo\u010dajo rekonstrukcijo izvirne vsebine, tudi \u010de je del kode fizi\u010dno po\u0161kodovan ali zakrit.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Obstajajo \u0161tiri standardizirane ravni popravljanja napak:<\/p>\n\n\n\n<figure>\n<table>\n<thead>\n<tr>\n<th>Raven<\/th>\n<th>Zmogljivost obnovitve<\/th>\n<th>Najbolj\u0161e za<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>L (nizko)<\/td>\n<td>~7%<\/td>\n<td>\u010cista notranja okolja<\/td>\n<\/tr>\n<tr>\n<td>M (srednje)<\/td>\n<td>~15%<\/td>\n<td>Splo\u0161ni marketin\u0161ki materiali<\/td>\n<\/tr>\n<tr>\n<td>Q (kvartil)<\/td>\n<td>~25%<\/td>\n<td>Industrijska ali zunanja uporaba<\/td>\n<\/tr>\n<tr>\n<td>H (visoko)<\/td>\n<td>~30%<\/td>\n<td>Kode z logotipi, te\u017eki pogoji<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">Vi\u0161je popravljanje napak pomeni, da koda lahko pre\u017eivi ve\u010d po\u0161kodb, vendar zahteva tudi ve\u010d modulov, kar povzro\u010di gostej\u0161i celoten simbol. \u010ce dodajate logotip QR kodi ali jo postavljate nekam, kjer je izpostavljena vremenskim vplivom, je izbira ravni H prava odlo\u010ditev.

Ta binarni niz se nato pretvori v \u010dloveku berljivo vsebino \u2013 URL, telefonsko \u0161tevilko, blok besedila, kontaktne informacije ali katero koli drugo vrsto podatkov, za katero je bila koda prvotno zgrajena.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">\u010ce koda vsebuje URL, va\u0161a naprava prika\u017ee poziv za odprtje.
