1. Ithini i-flight (ye-tof)

Ithini i-themera yeendiza? Ngaba ikhamera ekhupha indiza yendiza? Ngaba inento yokwenza neenqwelomoya okanye iindiza? Ewe, kunjalo kude kakhulu!

I-tof ngumlinganiso wexesha elithathayo, isuntswana okanye i-wave ukuya kumgama. Ngaba ubusazi ukuba inkqubo ye-bat yonyana ye-bat isebenza? Inkqubo yexesha lokuqhuba iyafana!

Zininzi iintlobo zenzwa-ye-flash, kodwa uninzi lweekhamera zeendiza kunye ne-laser Scansers, esebenzisa itekhnoloji ebizwa ngokuba yiLidar (efungelweyo kwaye ibuyise) ukulinganisa ubunzulu bamanqaku ahlukeneyo ngokuyikhanya kunye nokukhanya kwe-infrared.

Idatha eyenziwe kwaye ifakiwe kusetyenziswa izixhobo ze-TOF ziluncedo kakhulu njengoko zinokubonelela nge-Peestrings, ukungqinisisa umsebenzisi ngokusekwe kwi-Algomiting) i-Apgorithms, nangaphezulu.

Le nkqubo isetyenziswa ngokubanzi kwiirobhothi, iimoto oziphetheyo, kunye nefowuni yakho yeselula. Umzekelo, ukuba usebenzisa i-Huawei P30 Pro, yipare, i-PRE, i-LG G8 Cloq, njl.njl, ifowuni yakho inekhamera ye-tof!

2. Isebenza njani ixesha lokuvuka kwexesha?

Ngoku, singathanda ukunika intshayelelo emfutshane yendlela ye-sensor ye-flass kwaye isebenza njani.

I-tofIZIBHENGO ZABASEKHAYA I-LINTER YOKUGQIBELA UKUZIPHATHA NGOKUGQIBELA, apho ukukhanya okukhoyo kuyayiva nayiphi na into kwaye kubuyiswa kwi-sensor. Ngokusekwe umahluko wexesha phakathi kokukhanya kokukhanya kunye nokubuyela kwinzwa emva kokuba kuboniswe into, i-sensor inokulinganisa umgama phakathi kwento kunye nenzwa.

Namhlanje, siya kuphonononga iindlela ezi-2 ukuba zisebenzisa njani ixesha lokuhamba ukumisela umgama kunye nobunzulu: Sebenzisa ixesha lokutsala, kunye nokusebenzisa iSigaba sokutshintsha kwenqanaba le-Ampling

Sebenzisa i-pitses yexesha

Umzekelo, isebenza ngokukhanyisela ithagethi, emva koko ilinganisa ukukhanya okubonakalayo ngeskena, kwaye emva koko sisebenzise isantya sokukhanya sikwazi ukubala umgama ohanjisiweyo. Ukongeza, umahluko kwi-Laser I-Laser Imbuyekezo kwaye i-Wavelength isetyenziselwa ukwenza i-3D yedijithali yedijithali yedijithali kunye neempawu zomphezulu zethagethi, kwaye ikhuphe imaphu yemephu yayo.

Njengoko ubona ngaphezulu, ukukhanya kwe-laser kuyagxothwa kwaye emva koko kuqhume into ebuyela kwinzwa. Nge-Laser IXESHA, iikhamera ze-TOF ziyakwazi ukulinganisa imigama echanekileyo ngexesha elifutshane elinikwe isantya sokuhamba. .

(isantya sokukhanya x Ixesha lokubhabha) / 2

I-tof iguqula umgama

Njengoko ubona, ixesha eliya kuqala ngelixa ukukhanya kucinyiwe, kwaye xa umamkeli efumana ukukhanya, ixesha liya kubuya ixesha. Xa ukhupha kabini, "ixesha lokubhabha" lokukhanya lifunyanwa, kwaye isantya sokukhanya sihlala, ke umgama ungabalwa ngokulula usebenzisa ifomula ingentla. Ngale ndlela, onke amanqaku kumphezulu wento anokumiselwa.

Sebenzisa i-Shift yeSigaba se-Am

Emva koko, iI-tofUnokusebenzisa amaza aqhubekayo okufumanisa ukuba isiseko senqanaba lokukhanya okubonakalisiweyo ukumisela ubunzulu kunye nomgama.

I-Shift yeSigaba usebenzisa i-lamve

Ngokuyila i-implating, kudala umthombo wokukhanya okukhanyayo onayo nge-frequency eyaziwayo, evumela umtshisi ukuba amisele i-Shift yeSigaba sokuBoniswa:

Apho c isantya sokukhanya (c = 3 × 10 ^ 8 m / s), λ yi-wavelength (λ = i-15 m), inqaku ngalinye kwi-Expressor lingabalwa ngokulula kubunzulu.

Zonke ezi zinto zenzeka ngokukhawuleza njengoko sisebenza ngesantya sokukhanya. Ngaba ungayithelekelela indlela efanelekileyo kunye nesantya apho abantu banako ukulinganisa? Makhe ndinike umzekelo, ukukhanya kweekhilomitha ezingama-300,000 ngomzuzwana, ukuba into isuka kuwe, umahluko wexesha ukusuka kuwe, ukuba ibuyele kwi-33 Nanoseconds, elingana kuphela nemizuzwana engama-3.0000000333333 Wowu! Ukungakhankanyi, idatha efakiweyo iya kukunika ubungqina obuchanekileyo bedijithali ye-3D kwi-pixel nganye kumfanekiso.

Nokuba lo mgaqo usetyenzisiweyo, ubonelela ngomthombo wokukhanya oqokelela yonke into evumela i-sensor ukumisela ubunzulu bazo zonke iingongoma. Isiphumo esinjalo kukunika imephu yomgama apho i-pixel nganye ikhokelela khona kwindawo ehambelana nayo kwindawo efanelekileyo. Oku kulandelayo ngumzekelo wegrafu ye-TOF:

Umzekelo wegrafu ye-TOF

Ke kaloku siyazi ukuba i-tof isebenza, kutheni ilungile? Kutheni usebenzisa? Zithini izinto ezilungileyo? Sukuba nexhala, zininzi izibonelelo zokusebenzisa i-tof ye-TOF, kodwa ngokuqinisekileyo kukho umda.

I-3. Izibonelelo zokusebenzisa iinzwa zexesha lokubhabha

Ukulinganisa ngokuchanekileyo nangokukhawulezayo

Xa kuthelekiswa nezinye izinzwa zomda njenge-ultrasound okanye i-lasers, ixesha lezibhokopheli ze-flass liyakwazi ukwenza umfanekiso we-3D ngokukhawuleza. Umzekelo, ikhamera ye-TOF inokukwenza kuphela. Ayisiyiyo kuphela loo nto, i-tof sensor iyakwazi ukufumana izinto ngokuchanekileyo ngexesha elifutshane kwaye ayichaphazelekanga yi-themoids, uxinzelelo lomoya kunye neqondo lokushisa, lokwenza ilungele ukusetyenziswa phakathi kokungaphakathi nangaphandle.

umgama omde

Kuba izincedisi ze-TOF zisebenzisa i-lars, nazo ziyakwazi ukulinganisa imigama emide kunye ne-ranges ngokuchaneka okuphakathi. I-TOF ifungelweyo iyaguquguquka kuba bayakwazi ukubona kufutshane nezinto zonke iimilo nobungakanani.

Ikwaguquguquka ngengqondo yokuba uyakwazi ukwenza izinto ezibonakalayo zenkqubo yokusebenza ngokugqibeleleyo, apho unokukhetha khona iindidi zokuhambisa kunye neelensi zokufumana umbono ofunekayo.

Ukhuseleko

Ndinexhala lokuba i-laser evela kwiI-tofI-Sensor iya kwenzakalisa amehlo akho? subanexhala! Uninzi lwazo izinzwa ngoku sebenzisa i-leser ye-infrared ephantsi njengoMthombo wokukhanya kwaye uyiqhube ngeepuls zemodyuli. I-Eler Peveral Decles Inqanaba loku-1 lokukhuseleka kwemigangatho yokuqinisekisa kukhuselekile kwiliso lomntu.

isebenza kakuhle emalini

Xa kuthelekiswa nezinye iitekhnoloji ze-3D ezinzulu ze-3D ezinje ngeenkqubo zekhamera ezikhanyayo zekhamera okanye imigangatho ye-larefindlind, i-tof izifo zenzisi zishibhile kakhulu xa kuthelekiswa nazo.

Ngaphandle kwazo zonke ezi zinto zimiselweyo, i-tof isenokuthenjwa kakhulu kwaye yindlela ekhawuleza kakhulu yokufaka ulwazi lwe-3D.

4. Ukulinganiselwa kwe-tof

Nangona i-tof inezibonelelo ezininzi, ikwanemida. Eminye yemida ye-TOF ibandakanya:

• Ukukhanya okuqhelekileyo

Ukuba iindawo eziqaqambileyo kakhulu zisondele kakhulu kwiSensor yakho ye-TOF, zinokusasaza ukukhanya kakhulu kumvuzo wakho kwaye zenze ubugcisa kunye nezibonakaliso ezingafunekiyo, kuba i-TOF engafunekiyo kufuneka ilungele ukulinganiselwa kwakanye

• Ukucamngca ezininzi

Xa usebenzisa izixhobo ze-TOF kwiimbombo kunye neemilo zengcibi, zinokubangela ukubonakaliswa okungafunekiyo, njengoko ukukhanya kunokwenza amaxesha amaninzi, gxotha umlinganiso.

• Ukukhanya kokukhanya

Sebenzisa ikhamera ye-tof ngaphandle ukukhanya kwelanga okuqaqambileyo kunokwenza ukuba kungasebenzi kakuhle. Oku kungenxa yokuqina okuphezulu kokukhanya kwelanga kubangela i-pixels yenzwane ukuba ihambe ngokukhawuleza, yenze ukuba ingenzi ukuba ingenzi ukuba ifumane ukukhanya kwengqondo eboniswe kwinto leyo.

• Ukuqukumbela

I-TOF Inzwane kwayeI-tof lensinokusetyenziswa kwizicelo ezahlukeneyo. Ukusuka kwimephu ye-3D, i-Automation Automation Aute, imvume yokuzithoba, ezolimo, iroll, i-roboor, i-Indoor even, i-Scanson, i-Scansonce yeNdawo eQhelekileyo! Itekhnoloji ye-TOF ayinasiphelo.

Unganxibelelana nathi ngazo naziphi na iimfuno ze-lenses yetok.
