Chaza ngokufutshane itekhnoloji yokubhaqa iLiDAR
I-Lidar (Ukufumanisa Ukukhanya kunye nokuHlela) isebenzisa amaxabiso omgama wamafu/iiphikseli zeendawo ekujoliswe kuzo ukuqikelela imo yeethagethi ezinemilinganiselo emithathu (3D), kwaye iphuhlise ngokukhawuleza kwindlela yokuqonda imeko-bume engacwangciswanga efana nokuqhuba ngokuzimela, ukuhamba kweerobhothi, imephu yomhlaba, kunye nokubona kude.
Ngokungafaniyo netekhnoloji yemifanekiso ye-3D engasebenziyo enokubuyisela ulwazi lwe-3D kuphela lwezigcawu zokukhanya ezikufutshane, i-LiDAR inokufumana ulwazi lwe-3D olusebenzayo kwindawo engqongileyo kwaye idibanise ii-algorithms ezifana nokuveliswa kwelifu lenqaku, ukuhluzwa kwengxolo, ukubhaliswa kokulungelelanisa, kunye nenkcazo yeempawu ukuze kufezekiswe ukuqonda indawo. Ngokusekelwe kwiindlela ezahlukeneyo zokufumanisa ukukhanya, i-LiDAR ekhoyo inokwahlulwahlulwa ibe kukufumanisa ngokuthe ngqo kunye nokufumanisa okuhambelanayo.
Ukuchonga ngokuthe ngqo kusetyenziswa ukukhanya okushukumayo kunye nokufumanisa ubunzulu be-echo yethagethi nge-photodetector. I-LiDAR eqhelekileyo engacacanga yitekhnoloji yokujikeleza kwexesha lokubhabha (TOF) elawula usetyenziso oluninzi ngenxa yoqwalaselo lwayo lwehadiwe oluvuthiweyo kunye neendlela zokucubungula isignali. Nangona kunjalo, uluhlu lokufumanisa kunye nesisombululo se-TOF LiDAR zinqunyelwe kukusebenza kweisixhobo sokubona iifotokunye namandla aphezulu e-i-pulsed laser, kwaye isignali yayo ye-echo ingachaphazeleka kukukhanya kwelanga okanye enye inkqubo ye-radarilezaimiqadi.
Ngokwahlukileyo koko, ukufumanisa okucokisekileyo kusetyenziswa ubuchwepheshe bokuxuba i-optical phakathi kwe-echo beam kunye ne-local oscillator beam kunokumelana ngempumelelo nokuphazamiseka kokukhanya kokusingqongileyo kwaye kuphucule umlinganiselo wesignali-kwingxolo yenkqubo. I-LiDAR yendabuko ixhomekeke kakhulu kubunzulu, ii-coordinates ze-3D, okanye isantya somfanekiso, kwaye ubukhulu bolwazi olunganelanga bubangela ukuqondwa okulinganiselweyo kunye nokukwazi ukwahlulahlula ezi LiDAR. Ingakumbi kwiithagethi ezinezakhiwo ezahlukeneyo, kukho ukungacaci ekumiseleni ilifu lenqaku kwithagethi, okubangela ukungaqiniseki ekuqatshelweni kwesimo se-3D sethagethi.
Enye indlela enokwenzeka kukusebenzisa icandelo le-polarization lokukhanya, elinokuphucula ngempumelelo ukuqinisekiswa kwamafu/ii-pixels ze-target point. Ngokuhlalutya ukusebenzisana phakathi kokukhanya kwe-polarized kunye nezinto, ulwazi lwesakhiwo kunye nokwakheka kwe-target lunokuqondwa. I-Polarization coherent LiDAR idibanisa imiyalelo ephambili evela kwiinkalo ezahlukeneyo ezifana ne-optics, i-mechanics, ulawulo, kunye nolwazi lwe-elektroniki, igubungela iingcamango eziphambili ezifana nokufumanisa ulwazi, ukuskena kwe-beam, kunye nemifanekiso ye-polarization.
