Indlela i-LiDAR Ebona Ngayo Phakathi Kwemithi Ukwenza Imephu Yomhlaba
Xa ujonga phezulu esibhakabhakeni, ihlathi libonakala livaliwe ngokupheleleyo, kodwa eneneni kukho izikhewu ezincinci ezingenakubalwa phakathi kwamagqabi namasebe. I-drone LiDAR isebenzisa ezo zikhewu zincinci, idubula amakhulu amawaka emisebe ye-laser ngomzuzwana ukuze ifikelele emhlabeni phantsi kwemithi.
Esi sesona sizathu siphambili sokuba i-LiDAR ibe ngcono kakhulu kune-photogrammetry kwimimandla enengca nemithi emininzi. Ikhamera eqhelekileyo ithatha kuphela oko kubonakala phezulu, kodwa i-LiDAR igcina yonke idatha yemisebe ebuyayo, kubandakanywa naleyo ifikelele emhlabeni.

Ukukhutshwa Kwemisebe Exineneyo Kakhulu
Isivamvo sikhupha amakhulu amawaka emisebe ngomzuzwana, siqinisekisa ukuba emininzi ifumana izithuba.
Ukurekhoda Ukubuya Okuphindaphindiweyo (Multiple Returns)
Umsebe omnye ungabuya phezulu emthini, emasebeni nasezantsi emhlabeni njengamanqaku e-3D awohlukeneyo.
Ukwahlula Ukubuya Kokugqibela (Last Return)
Isoftware yahlula ukubuya kokugqibela komsebe ngamnye, okuyeyona ndawo ingumhlaba wokwenyani.
Ukwabiwa Komhlaba (Ground Classification)
Iinkqubo zekhompyuter zahlula ngokuzenzekelayo amanqaku omhlaba kwizityalo nakwingxolo.
Ukwenza Imephu Yomhlaba Ongenanto (Bare Earth Model)
Imodeli yokugqibela ye-DTM ibonisa indawo yomhlaba ngokungathi zange kubekho mithi apho.
Kwanasemahlathini axineneyo anama-90 ekhulwini e-canopy, ubuninzi bemisebe buqinisekisa ukuba idatha yomhlaba yanele ukwakha imodeli echanekileyo.
Ihlathi alize livaleke ngokupheleleyo. I-LiDAR idinga nje ukudubula ngokwaneleyo ukufumana apho kuvulekileyo.
Apho Obu Buchwepheshe Bubaluleke Khona Kakhulu
Uphando lwe-biomass yamahlathi, ukwenziwa kwemephu phantsi kwemithi, kunye novavanyo lweziseko ezingundoqo emahlathini kuxhomekeke koku. Iqela lethu le-drone survey lisebenzisa i-LiDAR scan ephucukileyo.
Ingaba unendawo enamahlathi ofuna ukuyenza imephu?
Sixelele ngendawo yakho kwaye siza kucacisa indlela uvavanyo lwe-LiDAR oluya kuyenza ngayo ngokugqibeleleyo.
Imibuzo Ebuzwa Rhoqo (FAQ)
I-LiDAR ikhupha amakhulu amawaka emisebe ngomzuzwana, kwaye emininzi idlula kwizithuba ezincinci zamagqabi ifike emhlabeni.
Kuxa umsebe omnye we-laser ubuya kwiindawo eziphakamileyo ezahlukeneyo njengaphezulu emthini, emasebeni nasemhlabeni ngokwahlukeneyo.
Hayi, ikhamera ithatha oko kubonakala phezulu kuphela kwaye ayikwazi kungena emithini.
Yimodeli yedijithali yendawo (DTM) apho kususwe yonke imithi nezakhiwo, kwasala umhlaba kuphela.
Ihlathi elixineneyo linciphisa ipesenti yemisebe efika phantsi, kodwa ukwandisa imisebe kugcina ukuchaneka kuphezulu.
Yinkqubo eyahlula ngokuzenzekelayo amanqaku omhlaba kwizityalo nakwingxolo kwi-point cloud.
Kuba ukubuya kokugqibela kumele eyona ndawo inzulu efikelelwe yi-laser, engumhlaba phantsi kwezityalo.
Ewe, ngokulinganisa ukuphakama kwemithi kunye nomhlaba ngaxeshanye, ivumela ukubala umthamo weenkuni ne-biomass ngokuchanekileyo.
Ewe, kuba i-LiDAR isebenzisa ukukhanya kwayo kwe-laser kwaye ayixhomekekanga ekukhanyeni kwelanga.
Ulawulo lwamahlathi, ukuhlolwa kwemigca yombane, uyilo lweendlela koololiwe, kunye nemigodi.
Le nombolo yenzelwe imibuzo yeprojekthi yorhwebo kuphela. Nceda ungaqhagamshelani nathi ngemiba yoqeqesho okanye imisebenzi.
