Fingerprint Kuzivikanwa Technology yeFingerprint Scanner

Kuzivikanwa kwemunwe wechigunwe kwechigunwe, mushandisi anongoda kuisa chigunwe cheminwe Maererano neimwe zano. Mechi kusvikira chigunwe chinogona kubudirira kufananidza iyo yekuisa chigunwe, kana kakawanda. Kufananidza, maererano nerudzi rwechiratidzo chekuzivikanwa, otomatiki munwe rj system yakakamurwa kuita mwemunwe wekuzivisa maitiro (kana inonzi 1: 1 System) uye Finerprint Kuzivikanwa System.

Iyo performes paramita yekuongorora iyo otomatiki yeminwe inozivikanwa system inogovaniswa muzvikamu zvitatu: Kurongeka marapita, nguva paramende uye nzvimbo yepadenga. Iyo inowanzoshandiswa kurongeka kurongeka inonyanya kusanganisira kukanganisa kwechiitiko, kukanganisa kweruva, et nguva yekunyoresa, etc. Iyo spatial parameter inonyanya kureva ndangariro dzakapihwa saizi uye template picha saizi / j. Kana iyo system yacho inoenderana neminwe miviri yeminwe, ivo vanowana yavo yekufananidza zviyero, izvo zvinogona kutariswa sekufanana. Pasina kurasikirwa neGlue, kufanana kunogona kuderedzwa kuenda [o, iwe, kuswededzwa kwakafanana neye zvigunwe zviviri, uye kuswededzwa kufanana kune O, mutsauko uri pakati peminwe miviri yeminwe . Kana ikapihwa yakafanana nechikumbaridzo Nenzira iyi, iyo yakafanana kuverenga kuverenga kukosha f, ipapo maviri ekukanganisa anokwanisa kuwanikwa, kureva iyo yekufananidza nyaya yekufananidza uye iyo nhema yeMismatching Rate:
.
(2) Kukanganisa Mismatch Rate MW, MNM-Hehhh (kana inonzi kukanganisa kurambwa kwemunwe wechigunwe, Mabasa e) achave akakura, kana 6 achiderera, nekuti DM: F (t), saka c inogona kuratidzwa se '= {((FMR) naFM, saka Delete r: 9 (*) = 8 ( F (Delete)) = H (FM min), wobva waramba basa reMB.
Kana iyo yakakwikwidza kurongeka inotorwa seyakakwikwidza kuronga, uye iyo yakarongedzwa kuronga inotorwa seyakagadziriswa kuronga, iyo ndege yehurongwa hwehurongwa hwakasimbiswa. Kana C inotora manhamba akasiyana, isu tinobatanidza mapoinzi ehurongwa hwekurongedza <mr (') uye kudzima rumbidzo axis, yakakwira kurongeka kwehurongwa.
