Ukuqalisa
Kusukela ngasekupheleni kweminyaka yama-1960s nasekuqaleni kwawo-1970, amasistimu amaningi endabuko endabuko athathelwe indawo yi-Airborne ne-Eerospace Electro-Optical and electronic sensor Sensor Systems. Ngenkathi izithombe zendabuko zendabuko zisebenza ngokuyinhloko eWavelength ebonakalayo ekhanyayo, izinhlelo zesimanje ezisuselwa ku-Airborne kanye nenhlabathi zikhiqiza idatha yedijithali emboza ukukhanya okubonakalayo, kuboniswe infrared, infrared ye-microwave. Izindlela zokutolizwa zendabuko ezibonakalayo ezithombeni zasemoyeni zisasiza. Noma kunjalo, ukuzwela okukude kuhlanganisa uhla olubanzi lwezicelo, kufaka phakathi imisebenzi eyengeziwe efana nemodeli ye-theorretical ye-Target Properties, izilinganiso zokubukeka kwezinto, nokuhlaziywa kwezithombe zedijithali ukuthola ukukhishwa kwemininingwane.
Ukuzwa okukude, okubhekisele kuzo zonke izici zamasu wokutholwa okude ongaxhumana naye, kuyindlela esebenzisa i-electromagnetism ukuthola, ukurekhoda nokukala izici zethagethi kanye nencazelo kuqala ngokuhlongozwa ngawo-1950. Inkambu yokuzwa okukude nemephu, ihlukaniswe ngezindlela ezi-2 ezizwakalayo: Ukuzwa okusebenzayo nokungenasisekelo, lapho kuzwakala khona ukuthathwa kwe-lidar kusebenza, ukwazi ukusebenzisa ukukhanya kwayo ukuze ngithole ukukhanya kulitshe bese ngithola ukukhanya okuboniswe kukho.
Ukuzwa okusebenzayo kwe-lidar nesicelo
I-Lidar (ukutholwa okukhanyayo nokusuka) ubuchwepheshe obukala ibanga ngokuya ngesikhathi sokukhipha nokwamukela amasiginali we-laser. Kwesinye isikhathi i-lidar yakwa-Airborne isetshenziswa ngokushintshana ngokuskena kwe-laser e-Airborne Laser, imephu, noma i-limbir.
Lokhu kungukugeleza okujwayelekile okubonisa izinyathelo eziphambili zokucutshungulwa kwedatha yePhoyinti ngesikhathi sokusetshenziswa kwe-lidar. Ngemuva kokuqoqa (x, y, z) ukuxhumanisa, ukuhlunga lawa maphuzu kungathuthukisa ukusebenza kahle kokuhlinzekwa kwedatha nokucutshungulwa. Ngaphezu kokucutshungulwa kwejometri lamaphoyinti we-lidar, imininingwane yokuqina evela kwimpendulo ye-lidar nayo iyasiza.
Kuzo zonke izicelo zokuzwa okukude nezinkomba, i-lidar inethuba elihlukile lokuthola izilinganiso ezinembile ngokwengeziwe ezizimele ukukhanya kwelanga neminye imiphumela yesimo sezulu. Uhlelo olujwayelekile lokuzwa olukude luqukethe izingxenye ezimbili, i-ranger ye-laser kanye nenzwa yokulinganisa yokubeka indawo, engalinganisa ngokuqondile indawo yendawo nge-3D ngaphandle kokuphazamiseka kwejometri ngoba i-3D World ifana ngendiza ye-2D).
