一, Lithini ixesha leekhamera leenqwelomoya?

Ikhamera ye-Fight (i-TOF) yohlobo lwetekhnoloji yokuziva inobunzulu elinganisa umgama phakathi kwekhamera kunye nezinto ezisengozini ngokusebenzisa ixesha kwaye zibuyele kwikhamera. Ziqhelekile ezisetyenziswa kwizicelo ezahlukeneyo ezifana nokukhutshwa kwenyani, iirobhothi, ukuskena kwe-3D, ukuvunywa komzimba, nangaphezulu.

Iikhamera ze-tofSebenza ngokukhupha uphawu lokukhanya, olukhanyisiweyo olukhanyisiweyo, kwaye ulinganise ixesha lokuthatha umqondiso ukuze uxhase izinto zendawo. Lo mgangatho wexesha emva koko usetyenziselwa ukubala umgama kwizinto, ukwenza imephu yobunzulu okanye ukumelwa kwe-3D yendawo.

Ixesha leekhamera zeNdiza

Xa kuthelekiswa nezinye iitekhnoloji ezinzulu ezinobunzulu obufana nokukhanya okwakhiwe okanye umbono weStereo, iikhamera ze-TOF zibonelela ngeenzuzo ezininzi. Babonelela ngolwazi lwexeshana elinzulu, yiba noyilo olulula, kwaye unokusebenza kwiimeko ezahlukeneyo zokukhanyisa. Iikhamera ze-TOF ziyaqulunqa kwaye zidityaniswe kwizixhobo ezincinci ezinjenge-smartphones, iitafile, kunye nezixhobo ezibhabha.

Izicelo zeekhamera ze-TOF ziyahluka. Ngeempawu zenyani, iikhamera ze-TOF zinokufumana ngokuchanekileyo ubunzulu bezinto kwaye ziphucule imbonakalo yezinto ezibonakalayo ezibekwe kwilizwe lokwenyani. Kwirobhothi, banika iirobhothi ukuze babone indawo abahlala kuyo kunye nokuhambahamba kwemiqobo ngakumbi. Kwi-Scanning ye-3D, iikhamera ze-TOF zinokufaka iJometri yeZinto okanye iindawo ezihlala iinjongo ezahlukeneyo njengenyani, umdlalo, okanye ukuprintwa kwe-3D. Zikwasetyenziswa nakwizicelo ze-biometric, ezinjengokuvunywa kobuso okanye ukuvela kwesandla.

二,Amacandelo eekhamera zenqwelomoya

I-Pames-ye-Bight (i-tof) iikhameraiquka izinto ezininzi eziphambili ezisebenza kunye ukwenzela ukuba ibone ubunzulu kunye nemilinganiselo yomgama. Amacandelo athile anokwahluka ngokuxhomekeka kuyilo nomenzi, kodwa nantsi izinto ezisisiseko ezifumaneka kwiinkqubo zekhamera ye-tof:

Umthombo wokukhanya:

Iikhamera ze-TOF zisebenzisa umthombo wokukhanya wokukhwela uphawu lokukhanya, zihlala zikwimo ye-infrared (ir) ukukhanya. Umthombo wokukhanya unokuba yi-LED (i-Diode ekhuphayo) okanye i-lar diode, kuxhomekeke kuyilo lwekhamera. Ukukhanya okukhutshelweyo kuhamba kwizinto ezisemoyeni.

I-Optics:

I-lens iqokelela ukukhanya okubonakalayo kunye nemifanekiso indalo esingqongileyo kwi-Solsor yoMfanekiso (I-Farlical Play). Icebo lokucoca i-band-Pass-Pass lidlulisele ukukhanya kunye ne-wavelength efanayo njengeyunithi yokukhanya. Oku kunceda ukucinezela ukukhanya okungapheliyo kwaye kuncitshiswe ingxolo.

Isivamvo somfanekiso:

Le yintliziyo yekhamera ye-TOF. I-pixel nganye ilinganisa ixesha lokukhanya okuthambileyo ukuba ihambe ukusuka kwiyunithi ekhanyayo (i-laser okanye i-LEFR okanye i-LED) kwinto leyo kwaye ibuyele kwindiza egxininisiweyo.

Ixesha lokufaka ixesha:

Ukulinganisa ixesha lokuhambahamba ngokuchanekileyo, ikhamera ifuna ukusekisha ixesha elichanekileyo. Olu sekelo lulawula ukukhutshwa komqondiso wokukhanya kwaye uqaphele ixesha elithathayo ukuze ukukhanya kube sezinto kwaye ubuye kwikhamera. Ilungelelanisa iinkqubo zokuphuma kunye nokuchonga ukuqinisekisa imilinganiselo ye-ofisi efanelekileyo.

Imodyuli:

EzinyeIikhamera ze-tofUkubandakanya ubuchwephesha bemozuluko yokuphucula ukuchaneka kunye nokusebenza kwemilinganiselo yomgama. Ezi khamerali zenza i-themeral ikhupha uphawu olukhutshelwe ngephethini ethile okanye rhoqo. Imo yokusebenzela inceda ukwahlula isibane esikhutshiweyo esivela kwezinye izinto ezikhanyayo zemfundo kwaye ziphucula amandla ekhamera yokwahlula phakathi kwezinto ezahlukeneyo zendawo.

Ibabalo le-algorithm:

Ukuguqula imilinganiselo ye-roba kwinkcukacha ezinzulu, iikhamera ze-TOF zisebenzisa i-algorithms enobuchule. Ezi algorithms zihlalutya idatha yexesha elifunyenweyo kwifoto yefoto kwaye zibale umgama phakathi kwekhamera kunye nezinto ezisemoyeni. I-Algorith enzulu iAlgorithMs ihlala ibandakanya ukuhlawula izinto ezifana nesantya sokukhanya, ixesha lokuphendula lokuphendula, kunye nokuphazamiseka okukhanyayo.

Imveliso yedatha enzulu:

Nje ukuba ubalo olunzulu, ikhamera ye-TOF ibonelela ngokunzulu kwedatha. Oku kuphumeza kunokuthatha indlela yemephu yenzulu, ilifu lenqaku, okanye ukumelwa kwendawo ye-3D. Idatha enzulu inokusetyenziswa zizicelo kunye neenkqubo zokwenza imisebenzi eyahlukeneyo njengokulandelwa kwento, i-aunted aunten, okanye irobhothi.

Kubalulekile ukuba uqaphele ukuba ukumiliselwa okukhethekileyo kunye nezinto zeekhamera ze-TOF kungahluka kubephesheya kubo bonke abavelisi kunye neemodeli. Ukuqhubela phambili kwetekhnoloji kunokwazisa izinto ezongeziweyo kunye nezixhasi ukuphucula ukusebenza kunye nokusebenza kweenkqubo zekhamera ye-TOF.
