Ukuthikamezeka nokuhlanekezelwa kwe-chromatic kuthinta kanjani amafayili ama-ima

1.chromatic ukuphazamiseka

1.1 Kuyini ukuguquguquka kwe-chromatic

Ukuhlukaniswa kwe-chromatic kubangelwa umehluko ekudlulisweni kwendaba. Ukukhanya kwemvelo kwakhiwa indawo ekhanyayo ebonakalayo enebanga lobude obungu-390 kuya ku-770 nm, kanti konke okunye kungumbukwane ongabonwa iso lomuntu. Ngoba izinto zinezinkomba ezahlukahlukene zokuphindisela zamaza we-wavelengths ahlukile wokukhanya okunemibala, ukukhanya kombala ngamunye kunesikhundla nokukhulisa okuhlukile, okuholela ku-chromatism yesikhundla.

1.2 Kungayithinta kanjani ikhwalithi yesithombe

(1) Ngenxa yobude obude obuhlukile kanye nenkomba ekhombayo yemibala ehlukene yokukhanya, iphoyinti-nto alikwazi ukugxila kahle ku-point-point elingu-ONE eliphelele, ngakho-ke isithombe sizofiphazwa.

(2) Futhi, ngenxa yokukhuliswa okuhlukile kwemibala ehlukene, kuzoba khona "imigqa yothingo" emaphethelweni amaphuzu ezithombe.

1.3 Ukuthinteka kwe-chromatic kuthinta kanjani imodeli ye-3D

Lapho amaphuzu esithombe “enemigqa ye-rainbow”, izothinta isoftware ye-3D yokumodela ukufanisa iphoyinti elifanayo. Kwinto efanayo, ukufaniswa kwemibala emithathu kungadala iphutha ngenxa "yolayini benkosazana". Lapho leli phutha liqoqeka likhulu ngokwanele, lizodala i- "stratification".

1.4 Ungakuqeda kanjani ukuphazamiseka kwe-chromatic

Ukusetshenziswa kwenkomba ehlukile yokubuyisa nokusabalalisa okuhlukile kokuhlanganiswa kwengilazi kungaqeda ukuphambuka kwe-chromatic. Isibonelo, sebenzisa inkomba yokubonisa ephansi nengilazi yokusabalalisa ephansi njengamalensi we-convex, nenkomba ephezulu yokubonisa kanye nengilazi yokusabalalisa ephezulu njengamalensi we-concave.

Ilensi ehlanganisiwe enjalo inobude obufushane bokugxila ebangeni eliphakathi nendawo nobude obude obude emisebeni yamagagasi emide futhi emifushane. Ngokulungisa i-lens eyindilinga eyindilinga, ubude obugxile bokukhanya okuluhlaza okwesibhakabhaka nokubomvu kungalingana ncamashi, okuqeda ngokuqhamuka ukuphambana kwe-chromatic.

I-spectrum yesibili

Kepha ukuguqulwa kwe-chromatic akukwazi ukuqedwa ngokuphelele. Ngemuva kokusebenzisa ilensi ehlanganisiwe, ukuphazamiseka kwe-chromatic okusele kubizwa nge- "spectrum yesibili". Uma ubude be-lens bude obude, ukushiyeka okuthe xaxa okusele kwe-chromatic. Ngakho-ke, ocwaningweni lwasemoyeni oludinga izilinganiso eziqonde kakhulu, i-spectrum yesibili ayinakunakwa.

Ngokwethiyori, uma ibhendi elikhanyayo lingahlukaniswa libe yizikhawu eziluhlaza okwesibhakabhaka noluhlaza okotshani nokubomvu, futhi kusetshenziswa amasu we-achromatic kulezi zikhathi ezimbili, i-spectrum yesibili ingasuswa ngokuyisisekelo. Kodwa-ke, kufakazelwe ngokubala ukuthi uma i-achromatic yokukhanya okuluhlaza nokukhanya okubomvu, ukuphambana kwe-chromatic kokukhanya okwesibhakabhaka kuba kukhulu; uma i-achromatic yokukhanya okuluhlaza okwesibhakabhaka nokukhanya okuluhlaza, ukuphambana kwe-chromatic kokukhanya okubomvu kuba kukhulu. Kubukeka sengathi le yinkinga enzima futhi ayinampendulo, i-spectrum enenkani yesibili ayinakususwa ngokuphelele.

I-ApochromaticI-APOubuchwepheshe

Ngenhlanhla, izibalo zethiyori zithole indlela ye-APO, okuwukuthola okokusebenza kwelensi ekhethekile yokukhanya okusabalalisiwe ngokukhanya okuluhlaza okwesibhakabhaka nokukhanya okubomvu kuphansi kakhulu futhi okukhanya okuluhlaza okwesibhakabhaka kuya kokukhanya okuluhlaza kuphakeme kakhulu.

I-Fluorite yinto ekhethekile, ukusabalala kwayo kuphansi kakhulu, futhi ingxenye yokusabalalisa okuhlobene nayo isondele kwizingilazi eziningi ezibonakalayo. I-Fluorite inenkomba yokubheka ephansi uma kuqhathaniswa, incibilika kancane emanzini, futhi inekhono elincane lenqubo nokuqina kwamakhemikhali, kepha ngenxa yezakhiwo zayo ezinhle kakhulu ze-achromatic, iba yinto ebonakalayo eyigugu.

Kunezimbalwa ezimbalwa ze-fluorite ezimsulwa ezingasetshenziselwa izinto ezibonakalayo emvelweni, kuhambisana nentengo yazo ephezulu nobunzima bokuyicubungula, amalensi e-fluorite afana nalalensi ephezulu. Abavelisi bamalensi abahlukahlukene baye bazikhandla ukuze bathole okuzoba esikhundleni se-fluorite. Ingilazi ye-fluorine-crown ingenye yazo, futhi ingilazi ye-AD, ingilazi ye-ED kanye nengilazi ye-UD yizinto ezinjalo.

Amakhamera weRainpoo oblique asebenzisa ingilazi ye-ED ephansi ngokweqile njengoba ilensi yekhamera ukwenza ukuphazamiseka nokuphazamiseka kube kuncane kakhulu. Ayigcini nje ngokunciphisa amathuba okusatshalaliswa, kepha futhi nomphumela wemodeli ye-3D usuthuthukiswe kakhulu, okuthuthukisa kakhulu umphumela wamakhona wokwakha kanye ne-facade.

2, Ukuhlanekezela

2.1 Kuyini ukuhlanekezela

Ukuhlanekezelwa kwamalensi empeleni kuyigama elijwayelekile lokuhlanekezelwa kombono, okungukuthi, ukuphambuka okubangelwa umbono. Lolu hlobo lokuhlanekezelwa luzoba nomthelela omubi kakhulu ekunemba kwe-photogrammetry. Ngemuva kwakho konke, inhloso ye-photogrammetry ukukhiqiza kabusha, hhayi ukwenza ihaba, ngakho-ke kuyadingeka ukuthi izithombe zikhombise imininingwane yesilinganiso sangempela sezici zomhlabathi ngangokunokwenzeka.

Kepha ngoba lokhu kuyisici se-lens (i-convex lens iguqula ukukhanya nelensi ye-concave ihlukanisa ukukhanya), ubudlelwano obuchazwe ekwakhekeni kokukhanya yilokhu: isimo esinciphile sokuqeda ukuphazamiseka nesimo se-sine sokuqeda ikhoma le-diaphragm asikwazi ukwaneliswa ngasikhathi sinye, ngakho-ke ukuhlanekezela kanye nokuphambuka okubonakalayo kwe-chromatic Okufanayo akunakususwa ngokuphelele, kuthuthukiswe kuphela.

Kulesi sibalo esingenhla, kunobudlelwano obulinganayo phakathi kokuphakama kwesithombe nokuphakama kwento, futhi isilinganiso esiphakathi kwalokhu kukhuliswa.

Kuhlelo lokucabanga oluhle, ibanga phakathi kwendiza yento nelensi ligcinwa lingaguquki, futhi ukukhuliswa kuyinani elithile, ngakho-ke kukhona ubudlelwane obulinganayo kuphela phakathi kwesithombe nento, akukho ukuphazamiseka nhlobo.

Kodwa-ke, ohlelweni lokucabanga langempela, njengoba ukuguquguquka okuyindilinga kweray enkulu kuyahluka ngokwanda kwe-angle yensimu, ukukhuliswa akusasuki njalo endizeni yesithombe sezinto ezihlanganisiwe, okungukuthi, ukukhuliswa maphakathi nesithombe nokukhuliswa komphetho akuhambelani, isithombe silahlekelwa ukufana kwaso nento leyo. Lokhu kukhubazeka okhubaza isithombe kubizwa ngokuthi ukuhlanekezela.

2.2 Ukuhlanekezelwa kukuthinta kanjani ukunemba

Okokuqala, iphutha le-AT (Aerial Triangulation) lizothinta iphutha lefu lephoyinti elicinene, ngaleyo ndlela iphutha elihlobene nemodeli ye-3D. Ngakho-ke, isikwele sisho impande (i-RMS Yephutha Lokuphinda) esinye sezinkomba ezibalulekile ezibonisa ukunemba kokugcina kokumodela. Ngokuhlola inani le-RMS, ukunemba kwemodeli ye-3D kungahlulelwa kalula. Inani elincane le-RMS, liphakamisa ukunemba kwemodeli.

2.3 Yiziphi izinto ezithinta ukuhlanekezelwa kwelensi

ubude bokugxila
Ngokuvamile, uma ubude begxila lensi egxilile bude ngokwengeziwe, kuncane ukuhlanekezela; uma kufishaniswa nobude obugxile kokunye, ukuhlanekezela kukhulu. Yize ukuhlanekezelwa kwelensi yobude obugqame kakhulu (i-tele lens) sekuvele kukuncane kakhulu, empeleni, ukuze kubhekwe ukuphakama kwendiza neminye imingcele, ubude obugxile belensi yekhamera yokuhlola emoyeni yinde kangako.Isibonelo, isithombe esilandelayo yi-lens lens ye-Sony 400mm. Uyabona ukuthi ukuhlanekezelwa kwelensi kuncane kakhulu, kucishe kulawulwe ngaphakathi kuka-0.5%. Kepha inkinga ukuthi uma usebenzisa le lens ukuqoqa izithombe ngokulungiswa kwe-1cm, futhi ukuphakama kwendiza sekuvele kungu-820m. Let drone ukundiza kule ndawo ayiyona neze ingokoqobo.

Ukusebenza kwelensi

Ukusebenza kwelensi kuyisinyathelo esiyinkimbinkimbi kunazo zonke futhi esinemba kakhulu kunqubo yokukhiqiza ilensi, okubandakanya okungenani izinqubo eziyi-8. Inqubo yangaphambilini ifaka i-nitrate impahla-umgqomo wokugoqa-isihlabathi elengayo-ukugaya, futhi inqubo yokuthumela ithatha i-core-coating-adhesion-ink coating. Ukulungiswa kokucubungula kanye nemvelo yokucubungula kunquma ngqo ukunemba kokugcina kwamalensi we-optical.

Ukunemba kokusebenza okuphansi kunomphumela obulalayo ekuhlanekezelweni kwe-imaging, okuholela ngqo ekuphambanweni kwelensi okungalingani, okungakwazi ukwenziwa ipharamitha noma ukulungiswa, okuzothinta kakhulu ukunemba kwemodeli ye-3D.

Ukufakwa kwelensi

Umdwebo 1 ukhombisa ukuthambekela kwelensi ngesikhathi senqubo yokufaka ilensi;

Umdwebo 2 ukhombisa ukuthi ilensi ayigxili ngesikhathi senqubo yokufakwa kwelensi;

Umdwebo 3 ukhombisa ukufakwa okulungile.

Ezimweni ezintathu ezingenhla, izindlela zokufaka ezimweni ezimbili zokuqala yonke ingumhlangano "ongalungile", ozocekela phansi isakhiwo esilungisiwe, okuholele ezinkingeni ezahlukahlukene njengokufiphala, isikrini esingalingani nokusabalalisa. Ngakho-ke, ukulawulwa okunemba okuqinile kusadingeka ngesikhathi sokucubungula nokuhlangana.

Inqubo yokuhlangana kwamalensi

Inqubo yokuhlangana kwelensi ibhekisa kwinqubo yemeneli yelensi jikelele kanye nenzwa ye-imaging. Amapharamitha njengokuma kwephoyinti eliyinhloko le-orientation elementi kanye nokuhlanekezela okuguquguqukayo kumapharamitha wokulinganiswa kwekhamera kuchaza izinkinga ezibangelwe yiphutha lomhlangano.

Ngokuvamile, uhla oluncane lwamaphutha womhlangano lungabekezelelwa (impela, ukuphakama kokunemba komhlangano, kungcono). Uma nje amapharamitha wokulinganisa enembile, ukuhlanekezelwa kwesithombe kungabalwa ngokunembe kakhudlwana, bese ukususwa kwesithombe kungasuswa. Ukudlidlizela kungadala nokuthi ilensi ihambe kancane futhi kudale ukuthi imingcele yokuhlanekezela ilensi iguquke. Yingakho ikhamera yendabuko yocwaningo lwasemoyeni idinga ukulungiswa futhi ilinganiswe kabusha ngemuva kwesikhathi esithile.

I-lens yekhamera ye-Rainpoo oblique

Kabili Gauβ isakhiwo

 Ukuthwebula izithombe kwe-Oblique kunezidingo eziningi zelensi, ukuba ngosayizi omncane, isisindo esincane, ukuphazamiseka kwesithombe esiphansi kanye nokuphambuka kwe-chromatic, ukukhiqizwa kabusha kombala okuphezulu, nokulungiswa okuphezulu. Lapho kuklanywa ukwakheka kwelensi, ilensi yeRainpoo isebenzisa isakhiwo esiphindwe kabili seGauβ, njengoba kukhonjisiwe kulo mfanekiso:
Isakhiwo sihlukaniswe ngaphambili kwelensi, i-diaphragm, nangemuva kwelensi. Ingaphambili nangemuva kungabonakala sengathi "kuyalingana" maqondana ne-diaphragm. Isakhiwo esinjalo sivumela okunye kokuphambuka kwe-chromatic okwenziwe ngaphambili nangemuva ukuthi kukhanselane, ngakho-ke kunezinzuzo ezinkulu ekulinganisweni nasekulawuleni usayizi welensi esikhathini esedlule.

Isibuko se-Aspheric

Kwikhamera ye-oblique ehlanganiswe namalensi amahlanu, uma ilensi ngayinye iphinda kabili ngesisindo, ikhamera izosinda kahlanu; uma ilensi ngayinye iphindwe kabili ngobude, khona-ke ikhamera etshekile okungenani izosinda ngosayizi ophindwe kabili. Ngakho-ke, lapho udizayina, ukuze uthole izinga eliphakeme lekhwalithi yesithombe ngenkathi uqinisekisa ukuthi ukuphambuka nevolumu kuncane ngangokunokwenzeka, amalensi e-aspheric kufanele asetshenziswe.

Ama-lens we-Aspherical angafaka kabusha ukukhanya okusakazeke ebusweni obuyindilinga emuva ekugxileni, hhayi kuphela okungathola isixazululo esiphakeme, kwenze iziqu zokukhiqiza umbala ziphakeme, kepha futhi kungaqedela ukulungiswa kokuphambuka ngenani elincane lamalensi, ukunciphisa inani lamalensi ukwenza ikhamera ilula futhi incane.

Ukulungiswa kokuhlanekezelwa ubuchwepheshe

Iphutha lenqubo yokuhlangana lizokwenza ukuthi ukuphazamiseka kwelensi tangential kukhuphuke. Ukunciphisa leli phutha lenhlangano inqubo yokulungisa okuhlanekezelwe. Lesi sibalo esilandelayo sikhombisa umdwebo wesikimu wokuhlanekezelwa kwethala lens. Ngokuvamile, ukufuduka kokuhlanekezela kuyalingana maqondana nesobunxele esingezansi —— ekhoneni eliphezulu kwesokudla, okukhombisa ukuthi ilensi ine-angle yokuzungeza ebheke ngqo esiqondisweni, esidalwa amaphutha womhlangano.

Ngakho-ke, ukuze kuqinisekiswe ukunemba okuphezulu kwe-imaging nekhwalithi, iRainpoo yenze uchungechunge lwamasheke aqinile ekwakhiweni, ekuqhutshweni nasekuhlanganisweni:

Esigabeni sokuqala sokuklanywa, ukuze kuqinisekiswe ukuhlangana kwenhlangano yamalensi, ngangokunokwenzeka ukuqinisekisa ukuthi zonke izindiza zokufakwa kwelensi zicutshungulwa ngocingo olulodwa;

②Ukusebenzisa amathuluzi okuguqula ingxubevange angenisiwe kuma-lathes asebenza kahle ukuze kuqinisekiswe ukuthi ukunemba kwemishini kufinyelela ezingeni le-IT6, ikakhulukazi ukuqinisekisa ukuthi ukubekezelelana kwe-coaxiality kungu-0.01mm;

LensIlensi ngayinye ifakwe isethi yamapayipi wensimbi we-tungsten ephezulu-ngokunemba ebusweni bangaphakathi oyindilinga (usayizi ngamunye uqukethe okungenani izindinganiso ezi-3 zokubekezelelana), ingxenye ngayinye ihlolwe ngokuqinile, futhi ukubekezelelana kwesimo okufana nokufana nokuqondakalayo kutholwa insimbi yokulinganisa emithathu;

Ngemuva kokuthi kukhiqizwe ilensi ngayinye, kufanele ihlolwe, kufaka phakathi ukulungiswa kwesilinganiso nokuhlolwa kweshadi, nezinkomba ezahlukahlukene njengokuxazululwa nokukhiqizwa kabusha kwelensi.
