Ukuvalwa kwabafundi kuyahlulahlula phakathi kobuso kunye neefoto?

Itekhnoloji yexesha lokuBala Le teknoloji isetyenziswa ikakhulu kukwamkelwa, njengezitshixo, ulawulo lwefowuni, ulawulo lokufikelela kunye nokuhlawulwa kobuso ekutyeni, njl. Umsebenzi wesazisi wokwenyani ngokwemvelo ubuso besixhobo. Ukuba ifoto, kuba iyafana nobuso bomntu kwimbono yenqwelomoya, indlela yokuphepha ingxaki yobuqhetseba yokutshintsha ubuso ngenene kunye nefoto.

Ngexesha lokuqatshelwa, umsebenzisi kufuneka abonakalise ukusebenzisana nentshukumo, anjengokulungisa, enze intetho ethile e-grimace, kuba kunzima ukufezekisa i-FREAGE, Ngokutsho koPhando lokwamkelwa kobuso ngokwesimo sokuvuma kwabasebenzi, ukufunyanwa kokuqhwanyaza yindlela ethembekileyo.
Ukuze unciphise inqanaba lempazamo kwimeko yokuqwalaselwa kobuso kunye nenkqubo yokubakho, le nkqubo isebenza ngolwazi olunzulu kwi-algorithm esetyenzisiweyo, kwaye i-scales ebukhali yefestile yobuso, leyo Ngaba, kude ubuso buvela kwikhamera, isakhelo sokufakwa kwedatha sincinci.
Le ndlela isebenzisa imisebe ekhethekileyo ye-infrared ukuba isebenze imephu yemitha ekhanyayo kwindawo enobunzulu, kwaye ngelixa inkqubo ingena kubuso obuncinci, ngoko ayisiyo ye-biometrics Endaweni yesisombululo ngokwawo, inokuba ngumgca ogxekayo-wenqanaba lendlela yokujonga kwi-fintle.
Sebenzisa ulwazi olunzulu ukufumana ubuso bevidiyo yedijithali, kwindawo, ukuba kukho abantu abaninzi, ubuso bunokupheliswa ngokomgama abantu abahlukeneyo abavela kwilensi. Ukuhamba kwam ubuso ngokubanzi kubandakanya ukwakhiwa kweetayile zokuthathwa kwetekhnoloji yobuso benkqubo, kubandakanya nokufunyanwa kobuso, ukubhengezwa kwesazisi, ukungqinelana kobuso kunye nokuhamba kwesazisi kwi Ingqondo emxinwa ibhekisa kwingqinisiso yesazisi okanye isiKhangeli sesazisi kwiTekhnoloji yeTekhnoloji okanye inkqubo.
Ukufunyanwa kobuthathaka yindlela yokufumanisa iimpawu zokwenyani zezinto zezinto zesazisi. Ukufunyanwa kobuthathaka kukhutshwa ikakhulu kubini, ukufunyanwa kokusebenzisana nentsebenziswano kunye nokwamkelwa kokungasebenzi kakuhle.
1. UKUFUMANEKA KWEXESHA LOKUGCINA
2. Ukufunyanwa kwakhona kokungasebenzi kakuhle: Ikhamera ye-infrared iqokelela imifanekiso ehlaziyiweyo, kwaye le nkqubo ayidingi ukuba isebenzisane nayo nayiphi na izenzo ezichaziweyo.
Apha ndiza kuthetha ngomahluko phakathi kweekhamera ze-infrared kunye neekhamera eziqhelekileyo. Xa kuthelekiswa neekhamera eziqhelekileyo, umahluko omkhulu phakathi kweekhamera ze-infrared kunye neekhamera eziqhelekileyo ngumahluko kumthombo wokukhanya. Okokuqala, kuba ingcinga yeekhamera, ukukhanya kudityaniswa kwizinto, ukusasazeka okwenzeka, kwaye kubonakaliswe njengenxalenye yokukhanya kuya kuthathwa yilensi yomthombo womfanekiso, emva koko uguqulwe ube ngumqondiso wombane , emva (a / d) Ukuguqulwa komfanekiso wedijithali, utshintshelwe kumqondiso wedijithali, emva koko uthunyelwe kwi-Dip yeDijithali yediji yedijithali ukuze itshintshelwe kwi-USB idluliselwe kwinkqubo kwaye ekugqibeleni idluliselwe kwi jonga.
Xa kuthelekiswa neekhamera eziqhelekileyo, umahluko omkhulu phakathi kweekhamera ze-infrared kunye neekhamera eziqhelekileyo ngumthombo wokukhanya. Umthombo wokukhanya weekhamera eziqhelekileyo uvela ngokukhanya okubonakalayo, oko kukuthi, ukukhanya kwelanga. Isibane esakhelweyo se-infrared sikhupha imitha ye-infrared, esasasazwayo esisasazeke kwaye samkelwe yikhamera emva kokuba incitshisiwe kwinto.
1. Ukucinga umgaqo
Siyazi ukuba ukuba ngaba lukhanyiso olubonakalayo okanye ukukhanya kwe-infrared, isiseko esisiseko ngamaza e-electromagnetic. Umfanekiso esiwubona ekugqibeleni sihambelana nepropathi ebonakalayo yomphezulu wezinto ezibonakalayo. Ubuso bokwenyani bomntu kunye nephepha, iimaski ze-massording ezintathu kunye nolunye umatshini wokuhlaselwa kweempawu zokubonisa zihlukile, ke loo maxesha akwahlukile, kwaye lo mahluko uya kubonakala ngakumbi ekubonakaliseni ukucingisisa. Umzekelo, kumfanekiso we-infrared ocinga ukuba kukho kuphela iqhekeza elimhlophe, hayi ubuso bomntu. , ukuze kuthintelwe kakubi.
2. eyakhelwe i-algorithm eyakhelweyo
Ngokwendlela yokuphuma ye-Optical, umahluko wexeshana kunye nokudibana kwedatha ye-pixel kwi-pixel yoqulo lwemifanekiso isetyenziselwa ukumisela ukuhamba kwezikhundla zePixel, kwaye inqaku elisebenzayo lePixel ifunyenwe kwi-Piection, esebenzisa iGaussian Isihluzi somahluko, iimpawu ze-LBP kunye neeVenkile zeNkxaso ngaxeshanye, intsimi yokuhambahamba yamehlo inobuthathaka ekuhambeni kwezinto, kwaye intsimi yokuhambahamba ingasetyenziselwa ukufumanisa ukunyuka kweliso kunye nokuqhwanyaza. Le ndlela yokufunyanwa enokufunyanwa ingafikelela ekufumaneni okungabonakaliyo ngaphandle kwentsebenziswano yomsebenzisi.
Ezinye iindlela zokugweba zibandakanya ukubongwa kobuso be-3D, okusebenzisa ikhamera ye-3D ukudubula ubuso, ukudibanisa idatha efunyenwe yikhamera, iqhelanisa nobuso, kwaye ekugqibeleni igwebe ukuba bubuso bokwenyani okanye ifoto.
