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.Isakaza 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, kanye nokugcina umbono onembile ezimweni zezulu eziyinselele.

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 ekwakhiweni 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 nokulungisa.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 kwamaqhinga.Ama-Drones afakwe i-LiDAR enza imisebenzi yokuhlola enembile, ehlinzeka ngobuhlakani obubalulekile.
I-Lumispot Tech igxile kakhulu kwi-LiDAR Laser Light Sources, imikhiqizo yethu iquketheI-1550nm Pulsed Fiber Laser, 1535nm Umthombo we-laser we-Automotive LiDAR, aI-1064nm Pulsed Fiber Laserokwe-OTDR kanyeInani eliphakeme kakhulu lama-TOF, njll.,Chofoza laphaukuze ubone uhlu lwethu lwemikhiqizo yomthombo we-laser ye-LiDAR.
