Bhalisela Imidiya Yethu Yezokuxhumana Ukuze Uthumele Ngokushesha
I-LiDAR, imele i-Light Detection kanye ne-Ranging, imele isiqongo kubuchwepheshe benzwa obukude. Isebenza ngokukhipha imishayo yokukhanya, ngokuvamile njengamalaser acijile, futhi ikala isikhathi esithathwayo ukuze le mishayo ibonakale ibuya ezintweni. Isakazeka ngesivinini sokukhanya, cishe i-3 × 108amamitha ngomzuzwana, i-LiDAR ibala ngokunembile ibanga ukuya entweni isebenzisa ifomula: Ibanga = Isivinini × Isikhathi. Lesi simangaliso sobuchwepheshe sithole ukusetshenziswa okuhlukahlukene emhlabeni jikelele, ukuguqula izinkambu kusuka ezimotweni ezizimele kuya ekuqashweni kwemvelo, nokusuka ekuhlelweni kwamadolobha kuye kokutholwe ngemivubukulo. Lokhu kuhlola okuphelele kuyacubungulaIzicelo ezingu-10 ezibalulekile ze-LiDAR, okubonisa umthelela wayo ojulile emikhakheni ehlukahlukene.
1. I-LiDAR Yezimoto
I-LiDAR ibalulekile endaweni yokushayela ngokuzenzakalelayo. Ikhiqiza amamephu emvelo ayinkimbinkimbi ngokukhipha kanye nokuthwebula ama-laser pulses. Lokhu kusebenza kuvumela izimoto ezizishayelayo ukuthi zibone ezinye izimoto, abahamba ngezinyawo, izithiyo, nezimpawu zomgwaqo ngesikhathi sangempela. Izithombe ze-3D ezikhiqizwe yi-LiDAR zinika amandla lezi zimoto ukuthi zikwazi ukuzulazula ezindaweni eziyinkimbinkimbi, ziqinisekisa ukuthathwa kwezinqumo okusheshayo nokuphephile. Ezindaweni zasemadolobheni, ngokwesibonelo, i-LiDAR ibalulekile ekutholeni izimoto ezimile, ukulindela ukunyakaza kwabahamba ngezinyawo, nokugcina umbono onembile ezimweni zezulu eziyinselele.

2. Imephu Yokuzwa Kukude
I-LiDAR ithuthukisa kakhulu ukunemba nokusebenza kahle kwemephu yendawo. Isetshenziswa ezindizeni noma kumasathelayithi, iqoqa ngokushesha idatha yesimo sezulu ezindaweni ezinkulu. Le datha ibalulekile ekuhleleni amadolobha, ukuhlaziya ubungozi bezikhukhula, kanye nokwakhiwa kwengqalasizinda yezokuthutha. I-LiDAR isiza onjiniyela ekuhlonzeni izinselele zendawo lapho behlela imigwaqo emikhulu emisha, okuholela emizileni enciphisa umthelela wemvelo futhi yandise ukusebenza kahle kokwakhiwa. Ukwengeza, i-LiDAR ingadalula izici ezifihliwe ze-topographical ngaphansi kwezitshalo, ezifakazela ukuthi ziwusizo ekuhloleni imivubukulo kanye ne-geological.

3. Ezamahlathi Nezolimo:
Ezamahlathi, i-LiDAR isetshenziselwa ukukala ubude besihlahla, ukuminyana, kanye nezici zokuma komhlaba, ezibalulekile ekuphathweni nasekulondolozweni kwehlathi. Ukuhlaziywa kwedatha ye-LiDAR kusiza ochwepheshe balinganisele i-biomass yehlathi, baqaphe impilo yehlathi, futhi bahlole izingozi zomlilo. Kwezolimo, i-LiDAR isekela abalimi ekubhekeni ukukhula kwezitshalo kanye nomswakama womhlabathi, ukwandisa izinqubo zokunisela, kanye nokuthuthukisa isivuno sezitshalo.
4. Izinzwa Zezinga Lokushisa Ezisabalalisiwe:
I-LiDAR ibaluleke kakhulu ekuzweleni izinga lokushisa esabalalisiwe, isici esibalulekile ekusethweni okukhulu kwezimboni noma izintambo zokudlulisa amandla. II-DTS LiDARiqapha ukude ukusatshalaliswa kwezinga lokushisa, ihlonza izindawo ezingaba khona ukuvikela amaphutha noma imililo, ngaleyo ndlela iqinisekise ukuphepha kwezimboni futhi ithuthukise ukonga kwamandla.
5. Ucwaningo Nokuvikelwa Kwemvelo:
I-LiDAR idlala indima ebalulekile ocwaningweni lwezemvelo kanye nemizamo yokongiwa kwemvelo. Isetshenziselwa ukuqapha nokuhlaziya izenzakalo ezifana nokukhuphuka kwezinga lolwandle, ukuncibilika kwezinguzunga zeqhwa, nokugawulwa kwamahlathi. Abacwaningi basebenzisa idatha ye-LiDAR ukuze balandelele izilinganiso zokuhlehla kwezinguzunga zeqhwa futhi bahlole imithelela yokushintsha kwesimo sezulu kuzinto eziphilayo. I-LiDAR iphinde iqaphe izinga lomoya ezindaweni zasemadolobheni nezolimo, okunomthelela ekuthuthukisweni kwezinqubomgomo ezisebenzayo zezemvelo.
6. Ukuhlelwa Nokuphathwa Kwedolobha:
I-LiDAR iyithuluzi elinamandla ekuhleleni nasekuphatheni amadolobha. Ukuqoqwa kwedatha ye-3D enokulungiswa okuphezulu kuvumela abahleli ukuthi baqonde kangcono izakhiwo zezindawo zasemadolobheni, okusiza ekuthuthukisweni kwezindawo zokuhlala ezintsha, izikhungo zezohwebo, nezindawo zomphakathi. Idatha ye-LiDAR ibalulekile ekuthuthukiseni imizila yezokuthutha zomphakathi, ihlole umthelela wokwakhiwa okusha kumadolobha, kanye nokuhlola umonakalo wengqalasizinda kulandela izinhlekelele.
7. Imivubukulo:
Ubuchwepheshe be-LiDAR buye baguqula umkhakha wemivubukulo, kwavula amathuba amasha okuthola nokufunda impucuko yasendulo. Ikhono layo lokungena ezimila eziminyene liye laholela ekutholakaleni kwezinto ezifihliwe nezakhiwo. Isibonelo, emahlathini ashisayo aseMelika Ephakathi, i-LiDAR yembule izinkulungwane zezindawo zamaMaya ezazingaziwa ngaphambili, zandisa kakhulu ulwazi lwethu ngale miphakathi yasendulo.
8. Ukulawulwa Kwezinhlekelele kanye Nezimpendulo Eziphuthumayo:
I-LiDAR ibaluleke kakhulu ekulawuleni izinhlekelele kanye nezimo eziphuthumayo. Ukulandela izehlakalo ezifana nezikhukhula noma ukuzamazama komhlaba, ihlola ngokushesha umonakalo, isiza emizamweni yokuhlenga neyokubuyisela. I-LiDAR iphinde iqaphe umthelela engqalasizinda, isekele izinhlelo zokulungisa nokwakha kabusha.

9. Ukuhlola Izindiza Nomkhathi:
Kwezokundiza, i-LiDAR isetshenziselwa ucwaningo lomkhathi, izilinganiso zokulinganisa ezifana nogqinsi lwamafu, izinto ezingcolisa umoya, nesivinini somoya. Ekuhloleni umkhathi, ihlomisa ama-probe namasathelayithi ukuze kuhlolwe okuningiliziwe kokuma kweplanethi. Isibonelo, ohambweni lokuhlola i-Mars lisebenzisa i-LiDAR ekudwebeni okubanzi kwemephu nokuhlaziya indawo ye-Mars.
10. Ezempi Nezokuvikela:
I-LiDAR ibalulekile ezicelweni zezempi nezokuvikela zokuthola kabusha, ukuhlonza okuhlosiwe, nokuhlaziywa kwendawo. Isiza ekuzulazuleni ezinkundleni zempi eziyinkimbinkimbi, ukutholwa kwezinsongo, nokuhlela ngendlela yamaqhinga. Ama-Drones afakwe i-LiDAR enza imisebenzi yokuhlola enembile, ehlinzeka ngobuhlakani obubalulekile.
