Iikhrayitheriya zikaJohnson zokufumana i-thermal yokucinga kunye nokwamkelwa

Imvelaphi yembali: Ngasekupheleni kweminyaka yee-1950, uJohn W. Umkhosi we-U.S.Ikhrayitheriya zikaJohnson - I-Wikipedia). Kwiphepha lakhe le-1958 "Uhlalutyo lweenkqubo zokwenza imifanekiso", UJohnson waxela imigudu yobukumkani (kwizibini ezibini kwithagethi) efunekayo kwimisebenzi eyahlukeneyo (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Ikhrayitheriya zikaJohnson - I-Wikipedia). Oku kwaziwa ngokuba Iikhrayitheriya zikaJohnson. I-IT SERTIONGY uyilo ngokuvumela iinjineli ukuba ziqikelele ukuba kude kangakanani na ukubonwa kangakanani na ukubonwa, ukwamkelwa, okanye kuchongwe phantsi kwemiqathango enikezwe (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Ikhrayitheriya zikaJohnson - I-Wikipedia). Sebenzisa ezi nkqubo, iimodeli ezininzi zokuqikelela zaphuhliswa kamva ukuba zilinganiswe nge-innersor ukusebenza phantsi kweemeko ezahlukeneyo zokusebenza (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Ikhrayitheriya zikaJohnson - I-Wikipedia).

Ukufunyanwa, ukwamkelwa, kunye nokuchongwa (imisebenzi ye-DRI)

Iikhrayitheriya zikaJohnson zichaza iprayimari ezintathu IMISEBENZI EBONELEKILEYO:

• Ukufunyanwa: Umbukeli uyayibona le nto ukuba into ikhona. . 1.0 ± 0.25 Izibini ezibini Ngaphesheya kwethagethi (Ikhrayitheriya zikaJohnson - I-Wikipedia).

• Ukwamkelwa: Umbukeli unokuxelela uhlobo lwento ngokubanzi (umzekelo, ukwahlula umntu ovela emotweni). Oku kufuna iinkcukacha ezingakumbi- ngokuqala malunga 4.0 ± 0.8 Izibini ezibini (Ikhrayitheriya zikaJohnson - I-Wikipedia).

• Ukuchonga: Umbukeli unokuchonga into ethile (E.G. Imodeli ethile yesithuthi okanye umntu othile). Lo ngowona msebenzi unzima, ofuna malunga 6.4 ± 1.5 Izibini ezibini (Ikhrayitheriya zikaJohnson - I-Wikipedia).

.Ikhrayitheriya zikaJohnson - I-Wikipedia).Ikhrayitheriya zikaJohnson - I-Wikipedia). Kwimifanekiso yokucinga yanamhlanje, ezi zinto zihlala zijikelezwe 1, 3, kunye nemijikelezo emi-6 I-50% yethuba lokwenza umsebenzi (Yintoni i-DRI, kwaye isekelwe yintoni i-counter?).

(Amahala mahala i-silhouette vector Art - Download 2,246 + madoda+ Amadoda Asisiki - IPixabay) Umzobo: Eyona nto ijolise kuyo. Kwi kuluhlu, ithagethi ivelisa kuphela i-silhouette emnyama (eyaneleyo yokufumana); Njengokusonjululwa (okanye ukusondela), ubuso kunye neempahla ezivela, zivele, ukunika imvume kunye nokuzicinywa ngokupheleleyo. Iikhrayitheriya zikaJohnson zibonisa ukuba zingaphi izibini zeenkcukacha ezifunekayo kwinqanaba ngalinye (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Yintoni i-DRI, kwaye isekelwe yintoni i-counter?).

Iikhrayitheriya zikaJohnson (imiqobo yokusombulula)

Iikhrayitheriya zoqobo zikaJohnson zihlala zishwankathelwa ngolu hlobo lulandelayo kwi-50% yempumelelo yomsebenzi ngamnye (Ikhrayitheriya zikaJohnson - I-Wikipedia):

• UKUFUMANEKA (Ubukho bomntu): ~ 1.0 I-TIPINIT ye-TIT kwithagethi (50% inokwenzeka) (Ikhrayitheriya zikaJohnson - I-Wikipedia).

• Ukwamkelwa (iklasi yento): ~ 4.0 Izibini ezibini kwithagethi (Ikhrayitheriya zikaJohnson - I-Wikipedia).

• Ukuchonga (into ethile): ~ 6.4 Izibini ze-6.4 zinethagethi (Ikhrayitheriya zikaJohnson - I-Wikipedia).

La maxabiso athatha i-degeest ePhezulu - Umahluko ongasemva kunye nombukeli ofanelekileyo. .Ikhrayitheriya zikaJohnson - I-Wikipedia).).Yintoni i-DRI, kwaye isekelwe yintoni i-counter?). Umzekelo, isikhokelo seNaTO esisebenzisa umjikelo omnye wokufumana, 3 ukuze iqwalaselwe, kunye ne-6 yokuchonga (Yintoni i-DRI, kwaye isekelwe yintoni i-counter?). (Umkhosi wase-U.S. Fumana Iikhrayitheriya zize zisebenzise i-0.75, 1.5, 3, 3, kunye nemijikelezo emi-6 yokufumanisa, hlula, uqaphele imisebenzi ehlaziyiweyo (Imbali kunye nokuvela kweMida yeJohnson).)

Iikhrayitheriya zikaJohnson zihlala zichazwe ngokulandelelana: ezinikiweyo N Imijikelezo kwithagethi, kukho amathuba angenayo ngokwenza umsebenzi ngamnye (i-Sigmoid - Njenge-50% kwimiba ebhalwe kuyo). Nangona kunjalo, isetyenziswa rhoqo njengomgaqo "wesithupha" esihambelana nesisombululo esifunekayo kulo msebenzi.

Isiseko sezibalo (isisombululo kunye noluhlu)

I Inani lemijikelezo ecocekileyo Ngaphesheya kuxhomekeka kubukhulu bethagethi, uluhlu, i-optics yenzwa, kunye ne-pixel. I-pinhole elula okanye imodeli yelensi yelensi (encinci ye-Angle - Ukufumanisa enye (Isiseko seNkqubo yokujonga izithuthi ezizenzekelayo):

phi n linani lemijikelezo kwithagethi, h_o Ngaba ubukhulu becala lezinto ezichaphazelekayo (m), f Ngaba ubude be-lens buye (iiyunithi ezifanayo njenge-pixel pitch), p Ngaba i-pixel pitch (umgama phakathi kwamaziko ePixel), kwaye R Uluhlu kwithagethi. Le fomula ibambe iziphumo ezithethwayo: Ithagethi enkulu (okanye ubude bemali) n, ngelixa i-pixel enkulu okanye ubude bayo buhla n (Isiseko seNkqubo yokujonga izithuthi ezizenzekelayo). Ukuba N Imijikelezo iyafuneka (kwitafile kaJohnson) yomsebenzi othile, Uluhlu lokufumanisa inokusonjululwa njenge

Umzekelo, ukuphindaphinda ubungakanani bethagethi okanye ubude obujolise kubude buphindwe kabini kuluhlu lwe N (Isiseko seNkqubo yokujonga izithuthi ezizenzekelayo). Ngokukwanjalo, ukuchitha i-pixel pitch (i.e. isisombululo esiphezulu se-EXMS) siphindwe kabini kuluhlu. Ezi fomula zihlala zisetyenziswa yikhamera ye-thermal prespe - Amaphepha okuqikelela i-D / R / I-ranges phantsi kweemeko ezifanelekileyo.

Izinto ezichaphazela uluhlu lokuchonga

Ifomula ye-fom elula ingentla ithatha umahluko ogqibeleleyo kunye neemeko ezicacileyo. Xa uziqhelanisa, uninzi lwezinto ezinefuthe lokufunyanwa kunye novavanyo.

• Ubungakanani bethagethi kunye nokwahlula: Iithagethi ezinkulu (ezide okanye ezide zibanzi) ziyabonakala ngomgama omkhulu; Ngokufanayo, ithagethi enobuntshatsheli obuphezulu (E.G. I-HORTER VOLE) i-vs epholileyo kunemvelaphi) kulula ukuyifumana. Kwiikhamera ze-thermal, inkathazo eqhelekileyo ngumahluko wobushushu we-~2 kwimvelaphi yokufumana okuqinisekileyo. Incinci okanye iphantsi - Ithagethi yenguqulelo ifuna imijikelezo emininzi (ngaloo ndlela kufutshane).

• Isisombululo seSensor & Iimpawu: Njengoko kubonisiwe, iipixels ezicocekileyo (ezincinci p) kwaye ubude obubi kakhulu f yonyusa uluhlu. Kwakhona, umsebenzi wokudluliselwa kwemozulu ye-Enor Kumazwi kaJohnson, izinto ezibonakalayo ezingcono (i-MTF ephezulu) inciphisa ngokufanelekileyo imijikelezo efunekayo yomsebenzi onikiweyo (Isiseko seNkqubo yokujonga izithuthi ezizenzekelayo).

• Iimeko ze-Atmospheric: I-Otinels yokwenyani ixhamla imiqondiso ye-infrared. Iziphumo zemvula, inkungu, okanye uthuli lunokunciphisa ubukhali. Iimodeli ezilula zisebenzisa umthetho webhiya (F_T = Exp (- r / l_r)) Ukutsala ugqithiso kwi-wavelength (Imbali kunye nokuvela kweMida yeJohnson). Izifundo ze-Pirirical Shog kunye nemozulu enzima inokufumana i-greatrictions ephantsi, nakwi-IR (Imbali kunye nokuvela kweMida yeJohnson). I-IR ye-thermal ir ihlupheka isuka kumphunga wamanzi kunokukhanya okubonakalayo, kodwa imozulu ebibisa isaziintlakathi eziqinileyo (Imbali kunye nokuvela kweMida yeJohnson) (Imbali kunye nokuvela kweMida yeJohnson).

• Imvelaphi ye-clutter: Imvelaphi ephezulu - Imvelaphi ye-clutter yenza nzima. Iimvavanyo zibonisa ukuba "kwi-clutter ephantsi" ye-johnson's johnson inokuba mncinci njenge ~ 0.5 yokuchonga imifanekiso efunyanweyo, kodwa i-Scertles "ye-Tript" ye-50% yokuKhangela (Imbali kunye nokuvela kweMida yeJohnson). Ukuziqhelanisa, imvelaphi efihlakeleyo okanye entsonkothileyo ihlala ifuna umahluko ojolise kuyo okanye isisombululo esingaphezulu kwe-Johnson.

• I-Sign - I-IT - Ingxolo yengxolo Uvimba we-thermal unengxolo (i-NET) kunye noluhlu olunamandla. Utyikityo olubuthathaka lwe-thermal okanye ingxolo yenzwa ephezulu iphakamisa imijikelezo efunekayo. Izifundo zigxininisa ukuba i-snr ephantsi isebenza njenge-blur: I-ITeras umfanekiso wemifanekiso kwaye inciphisa uluhlu olusebenzayo (Imbali kunye nokuvela kweMida yeJohnson).

Ngokudibeneyo, ezi zinto zithetha ukuba iikhrayitheriya zikaJohnson zinika i-ranges efanelekileyo. Nakuphi na ubalo olusebenzayo kufuneka lubandakanye i-themosmostic Translations, umahluko wethagethi, ingxolo ye-leonar, njl njl. Umzekelo kaJehnson. Ngokubanzi, i-equation eyinyani iphindaphinda i-formula ilula ngokubonakala okanye kwimo yokuhambisa ukwenza iakhawunti.

Imizekelo Ukubala

Sebenzisa le fomula ingentla, umntu unokuqikelela i-D / R / ndihlukumeza ikhamera enikiweyo kunye nethagethi. Umzekelo:

• Umzekelo: Umntu omde we-2M (h_o = 2m) igcinwe kwikhamera ye-thermal nge f = I-50mm kunye ne-pixel pitch p = 20μm (= 0.02mm). Usebenzisa umqobo we-johnson 1 - Umjikelo womnqophiso wokufunyanwa,

  $$R _ {\ rm ubude} = \ frac {2 \, \ umbhalo {MM} {mm} {mm}$$

  Ukuqonda (≈3 Imijikelezo) kunye nokuchongwa (≈6), i-rangs iba ≈833m kunye ne-≈417m ngokulandelelana (ukusukela kwi-\ propto1 / n $).

• UMXHOLO UMZEKELISO UMZEKELISO: Inqaku lesicelo se-leonardo Drs linika ithagethi lomntu (ubukhulu obuqiqileyo ~ 0.95m) kunye nekhamera ene-17μm kunye ne-7μm kunye ne-16,72mm ubude. Kwi-3 - Umsebenzi wokuNgephathela umjikelo, baqokelela uluhlu lokufumana amanqaku angama-50% malunga ne-157m. .

• Amaxabiso aqhelekileyo: Kwiimeko ezifanelekileyo (umahluko olungileyo, umoya ocacileyo), umthetho kaJohnson - Umzekelo, enye i-CITE ~ ~-~ 667m Ukwamkelwa, kunye ~ 333mYintoni i-DRI, kwaye isekelwe yintoni i-counter?).

Le mizekelo ibonisa indlela iikhrayitheriya zikaJohnson zingasetyenziswa ngokuthe ngqo ngayo kwi-Arithmetic elula. Okwenziweyo ngokwesiqhelo xa uziqhelanisa rhoqo ngenxa yezinto ezichazwe apha ngasentla.

Izicelo

Iikhrayitheriya zikaJohnson zisetyenziswa ngokubanzi ekuyileni nasekuphondweni Iinkqubo zokucinga ze-thermal Ngaphesheya kumasimi amaninzi:

• Emkhosini nokuzikhusela: Inkcazo-ntetho yasebusuku - Imibono yombono, ukubonwa kwe-thermal, kunye nokuhlolwa rhoqo kudweliso lwe-D / R / I-ranges esekwe kwiikhrayitheriya zikaJohnson (Ikhrayitheriya zikaJohnson - I-Wikipedia). Ukufunyanwa kwethagethi kunye nokwamkelwa (umhlobo vs bie) ebusuku xhomekeka kolu qikelelo. Iincwadi ezininzi zentsimi kunye namaxwebhu okuthenga kwakhona

• Khangela kwaye uhlangulwe / ukhuseleko: Ukuphatha okanye ukubekwa kwekhamera ye-themermal esetyenziselwa ukufumana abantu abalahlekileyo, okanye ukubeka iliso kwimilinganiselo, kunye nokusebenzisa imerikhi yeDU. Umzekelo, amaqela okuhlangula anokufuna ikhamera enokuthi fumana Umntu nge-1km kwaye qaphela nge-400m. Iikhrayitheriya zikaJohnson zibonelela ngesiseko senkcazo enjalo.

• Ukuhlolwa kunye nokunyanzeliswa komthetho: Indawo yokujikeleza, ukubeka iliso kwi-Petroli yeZilwanyana zasendle, kunye neenkqubo zokuchongwa kwezinto zisebenzisa le nkqubo yokuqikelela ukuba kude kangakanani na umntu onzwayo angayithatha umntu okanye imoto ebusuku. .

Kwimeko nganye, iikhrayitheriya zikaJohnson zinceda ukuguqulela iiparamitha zenziweyo

Ukunqongophala kunye nokuLungiso lwangoku

Ngaphandle kokuba luncedo, iikhrayitheriya zikaJohnson zibalulekile imida. Yimodeli ebonakalayo, enombono ofanelekileyo obala kangangokuba inyani - Iziphumo zehlabathi:

• Iimeko ezilula: Ithatha imvelaphi efanayo, eyahlukileyo yokuthelekisa, kunye nequla le-tell. Ayicwangciswanga kwi-cltter okanye ifihlakeleyo. Ekusebenzeni, ithagethi ngokuchasene nemvelaphi enobunzima inokufuna ukusonjululwa okungakumbi kunamaxabiso aphambili eJohnson (Imbali kunye nokuvela kweMida yeJohnson).

• Ingabamba iimpembelelo zendalo: Iikhrayitheriya zentsusa aziquki imeko yemozulu okanye i-themospic thando. Izifundo zigxininisa oko Akukho modeli ilula Ukuthimba ngokupheleleyo inkungu, imvula, kunye neziphumo zoMsi (Imbali kunye nokuvela kweMida yeJohnson) (Imbali kunye nokuvela kweMida yeJohnson). Iinkqubo zanamhlanje zihlala ziphinda-phinda ngekota yokutshintshelwa kwe-quatfic okanye isebenzise iimodeli zokubonakala ezibonakalayo.

• Izinto zabantu: Umsebenzi kaJohnson wasebenzisa ababukeli abaqeqeshiweyo phantsi kweemeko ezilawulwayo; Ayisihoya ukwahluka koqeqesho lokujonga, ingqalelo, ukukhathazeka, njl njl. Kunokubakho umahluko obalulekileyo phakathi kwabantu abafumaniweyo (Imbali kunye nokuvela kweMida yeJohnson).

• Isiginali kunye nokulungiswa: Imodeli iphatha umfanekiso ngokungathi ubekelwe kuphela yi-geometry (iiphikseli kunye ne-optics). Ayibandakanyi ingxolo yesandi (i-INTR), uluhlu lwamandla, okanye izixhasi zokulungisa imifanekiso. Nasiphi na i-Outbboard Orboard okanye ividiyo ye-ALGOROTIITMS inokuphucula isisombululo esisebenzayo, simeme iikhamera zokwenyani zihlala ziphumza imida ye-johnson engenanto.

• Ukugxila okufanelekileyo: Iikhrayitheriya zichazwa kwi-50% ye-50%. Abayichazi indlela yokusebenza ephuculwa njani ngesisombululo esingaphaya komgangatho, okanye ababamba ubuxoki - IIREKHODI ZE-ARM.

Ngenxa yezi zithuba, iindlela zokusebenza zale mihla zandisa indlela yeJohnson. Umzekelo, umkhosi we-U.S. Fumana Ulwazi-nkqubo lungalungelelanisi iimfuno zomjikelo (i-0.75 yokuhlola, njl.) Ngokusekwe kuvavanyo olubanzi (Imbali kunye nokuvela kweMida yeJohnson). Izixhobo ezininzi zohlalutyo ngoku zidibanisa i-MTF, i-snassic kunye ne-themospheric pilely ngokucacileyo. Abanye babandakanya i-theer-lamert thandet (njengaphakathi J - Imovie/T - ufezekisiwe Iimodeli (Imbali kunye nokuvela kweMida yeJohnson) okanye i-metrics ye-clutter. Abanye babeka endaweni yemingxunya enzima ngethiyori yeenkcukacha-manani Nangona kunjalo, iikhrayitheriya zikaJohnson zihlala zingumxholo ongumfanekiso kunye nokuqalisa okukhulu

Isishwankathelo, Iikhrayitheriya zikaJohnson zidibanisa isisombululo sendawo yenzwa yenzwa kwimisebenzi esebenzayo yokubona ithagethi. Ngokuvala ukuboniswa, ukwamkelwa, kunye nokuchonga ngokubhekisele kwi-Merages ethe tye ukwenza umsebenzi ngamnye onokwenza umsebenzi ngamnye phantsi kweemeko ezifanelekileyo (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Isiseko seNkqubo yokujonga izithuthi ezizenzekelayo). Ngelixa umntu emele enze ingxelo yenyani - Izinto zehlabathi ngalo naluphi na uyilo oluneenkcukacha, iikhrayitheriya zikaJohnson zisaxhasa kakhulu ukucaciswa kwekhamera yekhamera kunye noqikelelo lwentsebenzo namhlanje (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Imbali kunye nokuvela kweMida yeJohnson).

Imithombo: Iinkcazo eziphambili kunye neenqobo zokuziphatha zivela kumsebenzi wokuqala kaJohnson (Ikhrayitheriya zikaJohnson - I-Wikipedia) kunye nesishwankathelo kuncwadi (Ikhrayitheriya zikaJohnson - I-Wikipedia) (Yintoni i-DRI, kwaye isekelwe yintoni i-counter?). Uluhlu lweefom zokubalwa zilandele amalungelo anqabileyo - I-lensi ye-lens ekwiphepha lokubonisa (Isiseko seNkqubo yokujonga izithuthi ezizenzekelayo). Iziphumo ezizeleyo zokusingqongileyo kunye nezemibuzo zibhalwe - Izifundo zeNqaku (Imbali kunye nokuvela kweMida yeJohnson) (Imbali kunye nokuvela kweMida yeJohnson). Imizekelo eSebenzayo kunye nokuQaphela zivela kubavelisi kunye neengxelo zobugcisa (Yintoni i-DRI, kwaye isekelwe yintoni i-counter?).
