I-LiDAR, emele i-Light Detection and Ranging, imelela iqophelo eliphezulu kubuchwepheshe bokubona okukude. Isebenza ngokukhipha imisebe yokukhanya, ngokuvamile njenge-pulsed lasers, futhi ilinganisa isikhathi esithathwa yile misebe ukuze ibonakale emuva ezintweni. Isakazeka ngesivinini sokukhanya, cishe ama-3×108amamitha ngomzuzwana, i-LiDAR ibala ngokunembile ibanga eliya entweni isebenzisa ifomula: Ibanga = Isivinini × Isikhathi. Lesi simangaliso sobuchwepheshe sithole izinhlelo zokusebenza ezahlukahlukene emhlabeni jikelele, saguqula amasimu kusukela ezimotweni ezizimele kuya ekuqapheni imvelo, kanye nasekuhleleni amadolobha kuya ekutholakaleni kwezinto zakudala. Lokhu kuhlola okuphelele kungenaIzicelo eziyi-10 ezibalulekile ze-LiDAR, okubonisa umthelela wayo ojulile emikhakheni eyahlukene.
1. I-LiDAR Yezimoto
I-LiDAR ibalulekile emkhakheni wokushayela ngokuzimela. Ikhiqiza amamephu ezemvelo ayinkimbinkimbi ngokukhipha nokuthwebula ama-laser pulses. Lokhu kusebenza kuvumela izimoto ezizishayelayo ukuthi zibone ezinye izimoto, abahamba ngezinyawo, izithiyo, kanye nezimpawu zomgwaqo ngesikhathi sangempela. Izithombe ze-3D ezikhiqizwe yi-LiDAR zivumela lezi zimoto ukuthi zihambe ezindaweni eziyinkimbinkimbi, ziqinisekise ukwenza izinqumo ngokushesha nangokuphephile. Ezindaweni zasemadolobheni, isibonelo, i-LiDAR ibalulekile ekutholeni izimoto ezimile, ukulindela ukunyakaza kwabahamba ngezinyawo, kanye nokugcina umbono onembile ezimweni zezulu ezinzima.

2. Ukumapha Kokuzwa Okukude
I-LiDAR ithuthukisa kakhulu ukunemba nokusebenza kahle kwemephu yendawo. Isetshenziswa ezindizeni noma kumasathelayithi, iqoqa ngokushesha idatha yendawo ezindaweni ezinkulu. Le datha ibalulekile ekuhleleni amadolobha, ekuhlaziyweni kwezingozi zezikhukhula, kanye nokwakhiwa kwengqalasizinda yezokuthutha. I-LiDAR isiza onjiniyela ekuboneni izinselele zendawo lapho behlela imigwaqo emisha, okuholela emizileni enciphisa umthelela wemvelo futhi ikhulise ukusebenza kahle kokwakha. Ngaphezu kwalokho, i-LiDAR ingaveza izici zezindawo ezifihliwe ngaphansi kwezitshalo, okubonakala kuwusizo kakhulu ekuhloleni kwezinto zakudala kanye nezindawo.

3. Amahlathi kanye Nezolimo:
Kwezamahlathi, i-LiDAR isetshenziselwa ukukala ubude besihlahla, ubuningi, kanye nezici zokwakheka komhlaba, ezibalulekile ekuphathweni nasekulondolozweni kwamahlathi. Ukuhlaziywa kwedatha ye-LiDAR kusiza ochwepheshe ukulinganisa i-biomass yamahlathi, ukuqapha impilo yamahlathi, kanye nokuhlola izingozi zomlilo. Kwezolimo, i-LiDAR isekela abalimi ekuqapheni ukukhula kwezitshalo kanye nomswakama womhlabathi, ukuthuthukisa imikhuba yokunisela, kanye nokuthuthukisa isivuno sezitshalo.
4. Ukuzwa Kwezinga Lokushisa Okusatshalalisiwe:
I-LiDAR ibaluleke kakhulu ekuboneni izinga lokushisa elisabalalisiwe, okuyisici esibalulekile ezimisweni ezinkulu zezimboni noma emigqeni yokudlulisa amandla.I-DTS LiDARiqapha ukusatshalaliswa kwezinga lokushisa kude, ihlonza izindawo ezingaba khona ezishisayo ukuze ivimbele amaphutha noma imililo, ngaleyo ndlela iqinisekise ukuphepha kwezimboni futhi ithuthukise ukusebenza kahle kwamandla.
5. Ucwaningo Lwezemvelo Nokuvikelwa:
I-LiDAR idlala indima ebalulekile emizamweni yocwaningo lwezemvelo kanye nokulondolozwa. Isetshenziselwa ukuqapha nokuhlaziya izinto ezifana nokwenyuka kwezinga lolwandle, ukuncibilika kweqhwa, kanye nokugawulwa kwamahlathi. Abacwaningi basebenzisa idatha ye-LiDAR ukulandelela amazinga okuhoxa kweqhwa kanye nokuhlola imiphumela yokushintsha kwesimo sezulu ezindaweni zemvelo. I-LiDAR iphinde iqaphe ikhwalithi yomoya ezindaweni zasemadolobheni nezolimo, ifaka isandla ekuthuthukisweni kwezinqubomgomo zemvelo ezisebenzayo.
6. Ukuhlela Nokuphatha Amadolobha:
I-LiDAR iyithuluzi elinamandla ekuhleleni nasekuphatheni amadolobha. Ukuqoqwa kwedatha ye-3D enesinqumo esiphezulu kuvumela abahleli ukuthi baqonde kangcono izakhiwo zendawo zasemadolobheni, okusiza ekuthuthukisweni kwezindawo zokuhlala ezintsha, izikhungo zezentengiselwano, kanye nezikhungo zomphakathi. Idatha ye-LiDAR ibalulekile ekwenzeni ngcono imizila yezokuthutha zomphakathi, ukuhlola umthelela wokwakhiwa okusha ezindaweni zedolobha, kanye nokuhlola umonakalo wengqalasizinda ngemva kwezinhlekelele.
7. Izinto zakudala:
Ubuchwepheshe be-LiDAR bushintshe insimu yemivubukulo, buvula amathuba amasha okuthola nokufunda imiphakathi yasendulo. Amandla ayo okungena ezitshalweni eziminyene aholele ekutholakaleni kwezinto zobuciko nezakhiwo ezifihliwe. Isibonelo, emahlathini emvula aseMelika Ephakathi, i-LiDAR yembule izinkulungwane zezindawo zamaMaya ezazingaziwa ngaphambili, okuthuthukisa kakhulu ulwazi lwethu ngale miphakathi yasendulo.
8. Ukuphathwa Kwezinhlekelele Nokusabela Eziphuthumayo:
I-LiDAR ibaluleke kakhulu ekuphathweni kwezinhlekelele kanye nasezimweni zokusabela eziphuthumayo. Ngemva kwezehlakalo ezifana nezikhukhula noma ukuzamazama komhlaba, ihlola ngokushesha umonakalo, isize emizamweni yokutakula kanye nokulungisa. I-LiDAR iphinde iqaphe umthelela engqalasizinda, isekele izinhlelo zokulungisa nokwakha kabusha.
