Ho tloha bofelong ba bo-1960 le mathoasong a bo-1970, boholo ba litsamaiso tsa setso tsa ho nka lifoto tsa moeeng li nkeloe sebaka ke litsamaiso tsa li-electro-optical le tsa elektroniki tsa ho lemoha tse tsamaeang moeeng le sefofaneng. Le hoja ho nka lifoto tsa moea tsa setso ho sebetsa haholo-holo ka bolelele ba leqhubu la khanya e bonahalang, litsamaiso tsa sejoale-joale tsa ho lemoha tse tsamaeang moeeng le tse thehiloeng fatše li hlahisa data ea dijithale e koahelang khanya e bonahalang, libaka tsa infrared tse bonts'itsoeng, infrared ea mocheso, le libaka tsa spectral tsa microwave. Mekhoa ea setso ea tlhaloso ea pono ho nka lifoto tsa moeeng e ntse e thusa.

Ho lemoha hole, ho bolelang likarolo tsohle tsa mekhoa ea ho lemoha e sa amaneng le motho, ke mokhoa o sebelisang electromagnetism ho lemoha, ho rekota le ho lekanya litšobotsi tsa sepheo 'me tlhaloso e ile ea hlahisoa ka lekhetlo la pele lilemong tsa bo-1950. Tšimo ea ho lemoha hole le ho etsa 'mapa, e arotsoe ka mekhoa e 'meli ea ho lemoha: ho lemoha ho sebetsang le ho sa sebetseng, eo ho eona ho lemoha ha Lidar ho sebetsang, ho khonang ho sebelisa matla a eona ho ntša leseli ho sepheo le ho lemoha leseli le bonahatsoang ho sona.
Ho Sense le Tšebeliso ea Lidar e Sebetsang
Lidar (ho lemoha le ho pharalla ha leseli) ke theknoloji e lekanyang sebaka ho latela nako ea ho ntša le ho amohela matšoao a laser. Ka linako tse ling Airborne LiDAR e sebelisoa ka mokhoa o fapanyetsanang le ho hlahloba laser ea moea, ho etsa 'mapa, kapa LiDAR.
Ena ke chate e tloaelehileng ea phallo e bonts'ang mehato e meholo ea ts'ebetso ea lintlha tsa lintlha nakong ea ts'ebeliso ea LiDAR. Kamora ho bokella likhokahano tsa (x, y, z), ho hlophisa lintlha tsena ho ka ntlafatsa katleho ea tlhahiso le ts'ebetso ea lintlha. Ntle le ts'ebetso ea jeometri ea lintlha tsa LiDAR, tlhahisoleseling ea matla a tsoang ho karabelo ea LiDAR le eona ea thusa.
Lits'ebetsong tsohle tsa ho lemoha le ho etsa 'mapa hole, LiDAR e na le monyetla o ikhethang oa ho fumana litekanyo tse nepahetseng haholoanyane ntle le khanya ea letsatsi le litlamorao tse ling tsa boemo ba leholimo. Sistimi e tloaelehileng ea ho lemoha hole e na le likarolo tse peli, sesebelisoa sa laser rangefinder le sensor ea ho lekanya bakeng sa ho beha sebaka, tse ka lekanyang tikoloho ea jeokrafi ka kotloloho ho 3D ntle le ho sotha ha jeokrafi hobane ha ho na litšoantšo tse amehang (lefatše la 3D le nkiloe setšoantšong sefofaneng sa 2D).
