Kushanda zvigunwe zvigunwe sei

Kuzivikanwa kweminwe kuzivikanwa kwekunakidzwa kwehunyanzvi hwekuziva maitiro, kusanganisira module senge zvigunwe zvigunwe zvekutora kwemifananidzo, kugadzirisa, chimiro chekuratidzira uye kuenzanisa. Fingerprint mufananidzo kuwana: Live Fingerprint Mifananidzo inogona kuunganidzwa kuburikidza neanosarudzika zvigunwe zvigunwe. Parizvino, vateresi veminwe vanonyanya kusanganisira kurarama kwehupenyu, kugona uye kumanikidza vanoteerera. Zvehunyanzvi hwechiratidzo dzakadai sekugadzirisa uye nzvimbo yekuwana, iyo indasitiri yeruzhinji yeruzhinji yakagadzira zviyero zvepasi rese uye mudzimba, asi kuchine kushomeka kwezvakabatana zvinodiwa kune vamwe. Sekureva kwenzvimbo yeminwe yakaunganidzwa, inogona kukamurwa kuita mukudzikisira zvigunwe zvigunwe uye zvigunwe zvigunwe. Iyo yeruzhinji yekuchengetedza indasitiri kazhinji inoshandisa kudzikisira zvigunwe zvigunwe. Uye zvakare, iyo chifananidzo chemunwe inogona zvakare kuwanikwa kuburikidza ne scanner, kamera yedhijitari, uye yakadaro. Fingerprint mufananidzo compression: Yakakura-kugona zvigunwe zvigunwe zvigunwe zvinofanirwa kuchengetwa mushure mekumanikidza kuderedza nzvimbo yekuchengetedza. Nzira huru dzinosanganisira Jpeg, WSQ, etc. Fingerprint Area Kuongororwa, mufananidzo wemhando yekutonga, kufambisa kwemufananidzo, kuwedzeredza kufungidzira,

Chizvarwa chekutanga chekuzivikanwa kwemunwe uye kuenda kuchizvarwa chekutanga chekuzivikanwa kwemunwe uye kuenda kuchizvarwa chekutanga chekuzivikanwa kwemunwe uye kuenda kuchizvarwa chekutanga chekuzivikanwa kwemunwe uye kupinda kunozivikanwa. Makore maviri apfuura, mamwe mabhurumu emabhuku akashandiswa zvigunwe zvigunwe zvechiziviso kana vashandisi vanopinda mukati. Chekutanga chirango chakasvitswa panguva iyoyo yaive yeiyo yekuzivikanwa. Maererano nechirevo chazvino, chinofanira kunge chiri chechizvarwa chekutanga chemunwe munwe. Kupinda mune zvekutanga zvigunwe zvekunzwa kunogona kungoongorora nzvimbo yeganda, kana kuongorora yakafa ganda renzvimbo, asi haigoni kuenda zvakadzika muDermis nekuti mwenje haugone kupinda pamusoro peganda (yakafa ganda remagetsi). Mune ino kesi, kuchena kwemunwe wemunwe kunokanganisa zvakananga zvinozivikanwa. Kana paine guruva rakawanda paminwe yemushandisi, zvikanganiso zvekuzivisa zvinogona kuitika. Uyezve, kana vanhu vakaita ruoko rwemunwe munharaunda zvinoenderana neminwe yavo, vanogona zvakare kupfuudza nzira yekuzivikanwa. Kune vashandisi, hazvina kuchengeteka kwazvo uye chakagadzikana kushandisa. Chizvarwa chechipiri chemagetsi ezvekuita, chizvarwa chechipiri chenyama, chizvarwa chechipiri chemagetsi, uye chizvarwa che cappacitive sensors, the capacitive sensor tekinoroji inoshandisa gadziriro yepakati yemavara uye sensor Bhodhi, kuchinjika ndiro
Chechipiri-chizvarwa capcitive sensors tora chimiro chemapuranga maviri ecocacing, uye mipata uye mipata yeminwe yemunwe inova dielectric pakati pemaplate. Iyo sensor inoona shanduko mune inogara ichidya pasi pakati pezviviri kuti ubudise mufananidzo wemunwe. Nekudaro, sezvo pamusoro pehusimbe chakagadzirwa neSilicon zvinyorwa, zviri nyore kukuvadza, uye zvinoumba chifananidzo chebasa kuburikidza nemipata uye mitezo yeminwe yeminwe, saka chiyero chekuziva cheminwe yakasviba, yakanyorova zvigunwe, nezvimwe.
Wechitatu-chizvarwa bio-rf munwe zvigunwe scanner ikozvino yagadzirwa. Iyo RF sensor tekinoroji inoburitsa madiki eRF signals kuburikidza neye sensor pachayo, inopinda gungwa remugunwe kuti udzore chimiro chomukati kuti uwane iyo yakanakisa chifananidzo. Naizvozvo, kweminwe yakaoma, yechitatu-chizvarwa chekodhiyo frequency sensory zvigunwe, zvigunwe zvakaoma uye zvimwe zvigunwe zvakaoma zvinogona kupfuura kusvika pa99 @%, uye yekunyepedzera menyu simba rakasimba. Kugadzirisa dambudziko reminwe yemunwe wechigadziko, renji rakakura rekupisa: yakakodzera kwazvo kutonhora kana munzvimbo dzinopisa. Nekuti rf sensors gadzira yakakwirira-mhando mifananidzo, rf tekinoroji ndiyo yakanyanya kukosha uye yakasimba mhinduro. Kuwedzera kune izvi, mhando yepamusoro yemufananidzo inobvumidza iyo sensor kuti isakeuke pakuvimbika kwekusimbiswa, nekukasira kushandiswa kweRF sensor pfungwa kune chero munda uye kusunganidzwa kusiri kusundwa.
