Chaza kafushane ubuchwepheshe bokuthola i-LiDAR
I-Lidar (Ukutholwa Kokukhanya Nokulinganisa) isebenzisa amanani ebanga lamafu/amaphikseli ephoyinti eliqondiwe ukulinganisa ukuma kwezinhloso okunezinhlangothi ezintathu (3D), futhi ithuthuke ngokushesha ekuboneni indawo engahlelekile njengokushayela okuzenzakalelayo, ukuzulazula kwamarobhothi, imephu yendawo, kanye nokuzwa okukude.
Ngokungafani nobuchwepheshe bokuthwebula izithombe ze-3D obungabuyisela ulwazi lwe-3D kuphela lwezigcawu zokukhanya ezizungezile, i-LiDAR ingathola ngenkuthalo ulwazi lwe-3D lwendawo ezungezile futhi ihlanganise ama-algorithms afana nokukhiqizwa kwamafu ephuzu, ukuhlunga umsindo, ukubhaliswa kokuxhumanisa, kanye nencazelo yesici ukuze kufezwe ukuqonda kwendawo. Ngokusekelwe ezindleleni ezahlukene zokuthola ukukhanya, i-LiDAR ekhona ngokuvamile ingahlukaniswa ngokutholwa okuqondile kanye nokutholwa okuqondile.
Ukuthola ngqo kusetshenziswa ukukhanya okushukunyiswayo nokuthola ukuqina kwe-echo yethagethi nge-photodetector. I-LiDAR evamile engacacile ubuchwepheshe obusebenzisa isikhathi sokundiza (TOF) obulawula izinhlelo zokusebenza eziningi ngenxa yokucushwa kwayo kwehadiwe okuvuthiwe kanye nezindlela zokucubungula isignali. Kodwa-ke, ububanzi bokuthola kanye nesisombululo se-TOF LiDAR kunqunyelwe ukusebenza kwe-umshini wokuthola izithombekanye namandla aphezulu e-i-laser evuvukile, futhi isignali yayo ye-echo ingathinteka futhi ukukhanya kwelanga noma olunye uhlelo lwe-radari-laserimisebe.
Ngokuphambene nalokho, ukutholwa okuhlangene kusetshenziswa ubuchwepheshe bokuxuba optical phakathi kokukhanya kwe-echo kanye nokukhanya kwe-oscillator yendawo kungamelana ngempumelelo nokuphazamiseka kokukhanya kwemvelo futhi kuthuthukise isilinganiso sesignali-kuya-kumsindo wesistimu. I-LiDAR yendabuko incike kakhulu ekuqineni, izixhumanisi ze-3D, noma ijubane lokuthwebula izithombe, futhi ubukhulu bolwazi olunganele buholela ekuqaphelweni okulinganiselwe kanye namakhono okuhlukanisa ala ma-LiDAR. Ikakhulukazi kuma-targets anezakhiwo ezahlukahlukene, kukhona ukungaqondakali ekunqumeni ifu lephuzu ku-target, okuholela ekungaqiniseki ekuqaphelweni kwesimo se-3D se-target.
Enye indlela engenzeka ukusebenzisa ingxenye yokukhanya ehlanganisa i-polarization, engathuthukisa ngempumelelo ukuqiniseka kwamafu/amaphikseli e-target point. Ngokuhlaziya ukusebenzisana phakathi kokukhanya okuhlanganisiwe nezinto zokwakha, ulwazi lwesakhiwo kanye nokwakheka kwe-target lungacatshangwa. I-Polarization coherent LiDAR ihlanganisa iziqondiso ezisezingeni eliphezulu ezivela emikhakheni eminingi efana ne-optics, mechanics, control, kanye nolwazi lwe-elekthronikhi, ihlanganisa imibono eyinhloko efana nokutholwa kolwazi, ukuskena kwe-beam, kanye nokuthwebula izithombe ze-polarization.
