Ngabe ubuso bokuqashelwa ubuso buhlukanisa kanjani phakathi kobuso nezithombe?

Ubuchwepheshe besikhathi sokuqashelwa kobuso buyithuluzi lelo mshini lithola izithombe ngekhamera bese liphatha ukukhonjwa komuntu. Lobu buchwepheshe busetshenziselwa ukuqashelwa kobunikazi, njengezezimali, izikhiye zefoni ephathekayo, ukulawulwa kokufinyelela kanye nokukhokha kobuso ekuthengeni, njll. Umsebenzi wokuhlonza umuntu wangempela ngokwemvelo ubuso bedivayisi. Uma kuyisithombe, ngoba kuyafana nobuso bomuntu ovela embonweni wendiza, ukuthi ungakugwema kanjani inkinga yokukhohlisa yokubuyisela ubuso bangempela ngesithombe.

Ngesikhathi sokuqashelwa, umsebenzisi udinga kuphela ukwenza ubuso bobuso ukuba basebenzisane nesenzo, njengokulungiswa, benza isibonisi esithile, ngoba kunzima ukufeza isenzo esithile esikhethekile esithombeni, ngakho-ke kunzima ukufeza inkohliso yezithombe, Ngokusho kocwaningo lokuqashelwa kobuso bokuqashelwa ngokuya ngokuvuma kwezisebenzi, ukutholwa kokufiphala kuyindlela ethembekile kakhulu.
Ukuze sinciphise inani lephutha ekubosheni ubuso nohlelo lokubakhona, uhlelo lusebenza imininingwane ejulile kwi-algorithm yokutholwa kobuso obusetshenziswa ku-Photography ekhona, futhi inesikali ngobuhlakani usayizi wewindows wobuso ngokuya ngokuxhuma kwefasitela lobuso, lokho Kunjalo, ubuso busuka kwikhamera, okulandelayo uhlaka lokuthwebula luncane.
Le ndlela isebenzisa imisebe ekhethekile ye-infrared ukwenza imephu yokukhanya kwemisebe endaweni yesehlakalo, bese kuguqulwa kube yimephu yokujula, futhi ngenkathi uhlelo lukwazi ukubona umehluko, ngakho-ke akuyona ikhono lokubona umehluko phakathi kobuso obuthile, ngakho-ke akuyona i-biometric Esikhundleni sesixazululo ngokwaso, kungaba yisinyathelo esibucayi se-Line-of-Site ohlelweni olubanzi lokufakazela ubuqiniso.
Usebenzisa imininingwane yokujula ukuthola ubuso emifudlaneni yevidiyo yedijithali, endaweni yesehlakalo, uma kunabantu abaningi, ubuso bungahluleke ngokuya ngebanga labantu abehlukene abavela ku-lens. Ababekhona abakhona bobuso obujwayelekile empeleni bafaka phakathi ukwakhiwa kokuqashelwa kobuso uchungechunge lobuchwepheshe obuhlobene, ukufakwa kobuso, ukufunwa kobuso, ukusesha kobuso, njll., Kanye nokwamukelwa kobuso ku Umuzwa omncane ubhekisele ekuqinisekisweni kobunikazi noma umazisi usesho ngobuchwepheshe noma ohlelweni.
Ukutholwa kokubuyiselwa kwemali kuyindlela yokuthola izici zangempela zomzimba zezinto kwezinye izimo zokuqinisekisa umazisi. Ukutholwa kokubuyiselwa kwemali kuhlukaniswe ngezinhlobo ezimbili, ukutholwa kokubumbana kokubambisana nokubonwa kokuqina kokungasebenzi kahle.
1. Ukutholwa kokubumbana kokubambisana: Uhlelo lokutholwa kobuso luthumela ezinye izenzo zomyalo ezingahleliwe, njengokufiphala, ukuguqula ikhanda nokuvula umlomo.
2. Ukutholwa kwe-infection okungeyona yokubambisana: Ikhamera ye-infrared iqoqa izithombe zokutholwa okucwengekile, futhi le nqubo ayidingi ukubambisana nanoma yiziphi izenzo ezibekiwe.
Lapha ngizokhuluma ngomehluko phakathi kwamakhamera we-infrared kanye namakhamera ajwayelekile. Uma kuqhathaniswa namakhamera ajwayelekile, umehluko omkhulu kakhulu phakathi kwamakhamera we-infrared namakhamera ajwayelekile umehluko emthonjeni okhanyayo. Okokuqala, ukucatshangelwa kwamakhamera, ukukhanya kuthambekele ezintweni, ukuhlukanisa ukusabalalisa kwenzeka, futhi kuboniswe ingxenye yokukhanya okuzotholwa yilensi yokugxila ebusweni besithombe se-lens, bese iguqulwa ibe yisiginali kagesi , ngemuva (a / d) ukuguqulwa kwe-analog-kuya ku-digital, kuguqulwe kube yisiginali yesithombe sedijithali, bese kuthunyelwa kwi-chip yesiginali yedijithali yokucutshungulwa, futhi ekugcineni nge-USB isikhombimsebenzisi esidluliselwe ohlelweni futhi ekugcineni sikhonjiswe ku- Gada.
Uma kuqhathaniswa namakhamera ajwayelekile, umehluko omkhulu phakathi kwamakhamera we-infrared namakhamera ajwayelekile ngumthombo wokukhanya. Umthombo wokukhanya wamakhamera ajwayelekile uvela ekukhanyeni okubonakalayo, okungukuthi, ukukhanya kwelanga. Isibani esakhelwe ngaphakathi sikhipha imisebe ye-infrared, ehlakazeka futhi yatholwa yikhamera ngemuva kokuvalelwa entweni.
1. Isimiso sokucabanga
Siyazi ukuthi noma kukhanya okubonakalayo noma okukhanyayo, umnyombo oyisisekelo amagagasi e-electromagnetic. Isithombe esisibona ekugcineni sihlobene nezakhiwo ezibonakalayo zobuso bezinto ezibonakalayo. Ubuso bangempela bomuntu kanye nephepha, izikrini, imaski emithathu-ntathu kanye neminye imithombo yokuhlaselwa izici zokubonisa konke kuhlukile, ngakho-ke umcabango uhlukile futhi, futhi lo mehluko uzoba sobala ngokwengeziwe ekubonisweni kwe-wave efrared. Isibonelo, esithombeni sokucabanga esimnandi se-infrared sesikrini, kukhona kuphela ucezu lwezimbali ezimhlophe, ngisho nobuso bomuntu. , ukuze kugwenywe ukwahlulela okungafanele.
2. I-algorithm eyakhelwe ngaphakathi
Ngokusho kwendlela yokugeleza kwe-Optical, ukuguquguquka kwesikhashana kanye nokuhlangana kwedatha yokuqina kwePixel ekulandekeni kwesithombe kusetshenziselwa ukunyakaza kwezikhundla ze-pixel ezifanele, kanye nemininingwane esebenzayo yephoyinti ngalinye lePixel itholakala ekulandekelweni kwesithombe, kusetshenziswa iGaussian Isihlungi somehluko, izici ze-LBP kanye nemikhakha yokusekela ngasikhathi sinye, insimu yokugeleza kwe-Optical izwela ukunyakaza kwezinto, futhi insimu yokugeleza kwe-Optical ingasetshenziswa ukuze ibone ukunyakaza kwamehlo nokufiphala. Le ndlela yokuthola bukhoma ingafinyelela ukutholwa okuyimpumputhe ngaphandle kokubambisana komsebenzisi.
Ezinye izindlela zokwahlulela zifaka ukutholwa kobuso be-3D, ezisebenzisa ikhamera ye-3D ukudubula ubuso, kuhlanganisa imininingwane etholwe yikhamera, ivumelanisa ubuso, futhi ekugcineni bahlulela ukuthi ngabe kungubuso bangempela noma isithombe.
