ʻElua-dimensional code" target="_blank">Ua kapa ʻia ke code ʻelua-dimensional code QR, a ʻo ka inoa piha ʻo QR ʻo Quick Response. Hiki i ka ʻike ke hōʻike i nā ʻano ʻikepili hou aʻe.
Hoʻopaʻa i ka ʻike hōʻailona ʻikepili me kahi kiʻi geometric kikoʻī i puʻunaue ʻia ma luna o kahi mokulele (ʻelua-dimensional kuhikuhi) e like me kekahi mau lula;Ke hoʻohana nei i nā manaʻo o "0" a me "1" bit streams i lilo i kumu noʻonoʻo o ka lolouila, me ka hoʻohana ʻana i kekahi mau ʻano geometric e pili ana i ka binary e hōʻike i ka kikokikona a me ka ʻike helu, heluhelu ʻakomi ma o nā lako hoʻokomo kiʻi a i ʻole nā ​​​​mea hana kiʻi kiʻi kiʻi no ka hoʻokō ʻana i ka hana Automatic o ka ʻike: loaʻa iā ia kekahi mau hiʻohiʻona maʻamau o ka ʻenehana barcode: aia kēlā me kēia ʻōnaehana code i kona ʻano kikoʻī;noho kēlā me kēia ʻano i kahi ākea;loaʻa iā ia kahi hana hōʻoia, a me nā mea ʻē aʻe. Ma ka manawa like, loaʻa iā ia ka hana o ka ʻike maʻalahi o ka ʻike ma nā lālani like ʻole, a me ka hana ʻana o ka rotation kiʻi a me nā helu hoʻololi.
Nā hiʻohiʻona
1. Kiʻekiʻe-density coding, nui ʻike hiki ke hoʻokomo i 1850 mau hua nui a i ʻole 2710 helu a i ʻole 1108 bytes, a ʻoi aku paha ma mua o 500 mau huaʻōlelo Kina, ʻoi aku ka nui o nā manawa ma mua o ka mana ʻike barcode maʻamau.
2. Ka laulā coding ākea: hiki i ka barcode ke hoʻopili i nā kiʻi, nā leo, nā huapalapala, nā pūlima, nā manamana lima a me nā ʻike helu helu ʻē aʻe, a hōʻike iā lākou me nā barcode;hiki iā ia ke hōʻike i nā ʻōlelo he nui;hiki ke hōʻike i ka ʻikepili kiʻi.
3. ʻO ka ʻae ʻana i ka hewa ikaika a me ka hana hoʻoponopono hewa: hiki i kēia ke heluhelu pololei ʻia ka barcode ʻelua-dimensional i ka wā i pōʻino hapa ʻia ma muli o ka perforation, contamination, etc.
4. Kiʻekiʻe decoding hilinaʻi: He oi haʻahaʻa ma mua o ka maʻamau barcode decoding helu kuhi hewa o 2/1000000, a me ka hapa hapa hapa 'aʻole i oi aku mamua o 1/10000000.
5. Hiki ke hoʻokomo ʻia nā hana hoʻopunipuni: maikaʻi ka hūnā a me ka anti-hoʻopunipuni.
6. Ke kumu kūʻai haʻahaʻa, maʻalahi e hana, a paʻa.
7. Hiki ke hoʻololi i ke ʻano, ka nui a me ka lakio o nā hōʻailona barcode.
8. Hiki ke heluhelu ʻia nā barcode 2D me ka hoʻohana ʻana i nā mea heluhelu laser a i ʻole CCD.
