Ikhowudi enamacala amabini" target="_blank">Ikhowudi enamacala amabini ikwabizwa ngokuba yiKhowudi yeQR, kwaye igama elipheleleyo le-QR yiMpendulo eKhawulezayo. Yindlela ethandwa kakhulu yokubhalwa kwekhowudi kwizixhobo eziphathwayo kwiminyaka yakutshanje. Ingagcina okuninzi. Ulwazi lungaphinda lubonise iindidi ezininzi zedatha.
Ikhowudi yebha ene-dimensional-dimensional/two-dimensional bar code (i-2-dimensional bar code) irekhoda ulwazi lwesimboli yedatha kunye nomfanekiso othile wejometri osasazwe kwinqwelomoya (icala-mbini) ngokwemigaqo ethile; Ukusebenzisa iikhonsepthi zika "0" kunye no "1" bit streams ezenza isiseko esinengqiqo sekhompyuter, kusetyenziswa iimilo ezininzi zejiyometri ezihambelana nokubini ukumela umbhalo kunye nolwazi lwamanani, ukufunda ngokuzenzekelayo ngesixhobo sokufaka umfanekiso okanye isixhobo sokuskena sombane ukuphumeza ukusetyenzwa okuzenzekelayo. yolwazi: ineempawu eziqhelekileyo zeteknoloji yebhakhowudi: inkqubo yekhowudi nganye ineseti yeempawu zayo ezithile; umlinganiswa ngamnye uthatha ububanzi obuthile; inomsebenzi othile wokuqinisekisa, njl. Ngelo xesha, nayo inomsebenzi wokuchongwa ngokuzenzekelayo kolwazi kwimigca eyahlukeneyo, kunye nokuqhutyelwa kokujikeleza kwegraphic kunye nokutshintsha amanqaku.
Iimbonakalo
1. Ikhowudi yoxinaniso oluphezulu, umthamo omkhulu wolwazi: unokufaka ukuya kuthi ga kwi-1850 oonobumba abakhulu okanye iinombolo ezingama-2710 okanye iibhayithi ze-1108, okanye ngaphezu kwama-500 oonobumba baseTshayina, amaxesha amaninzi aphezulu kunomthamo wolwazi lwebhakhowudi eqhelekileyo.
2. Uluhlu olubanzi lweekhowudi: ikhowudi yebhakhowudi inokufaka iikhowudi kwimifanekiso, izandi, abalinganiswa, iisignesha, iminwe kunye nolunye ulwazi olufakwe ekhompyutheni, kwaye ivakaliswe ngeebhakhowudi; inokumela iilwimi ezininzi; inokumela idatha yomfanekiso.
3. Ukunyamezelana okunamandla kunye nomsebenzi wokulungisa iimpazamo: oku kwenza ukuba ibhakhowudi emacala mabini ifundwe ngokuchanekileyo xa yonakaliswe ngokuyinxenye ngenxa yokugqobhoza, ukungcoliseka, njl. njl., kwaye ulwazi lusenokubuyiselwa xa indawo eyonakeleyo ifikelela kuma-50%.
4. Ukuthembeka kwe-decoding ephezulu: Kuphantsi kakhulu kunomlinganiselo wempazamo ye-barcode ye-decoding ye-2/1000000, kwaye i-bit error rate ayidluli kwi-1/10000000.
5. Amanyathelo okufihlakala anokwaziswa: ubumfihlo kunye nokuchasana nokukhohlisa kulungile.
6. Ixabiso eliphantsi, kulula ukwenza, kwaye lihlala ixesha elide.
7. Ubume, ubungakanani kunye nomlinganiselo weesimboli zebhakhowudi zingatshintshwa.
8. Iibhakhowudi ze-2D zinokufundwa kusetyenziswa i-laser okanye i-CCD readers.
