Ukuqhathanisa Okulula phakathi kuka-905nm no-1.5μm LiDAR
Masenze lula futhi sicacise ukuqhathanisa phakathi kwezinhlelo ze-LiDAR ze-905nm ne-1550/1535nm:
| Isici | 905nm LiDAR | 1550/1535nm LiDAR |
| Ukuphepha Kwamehlo | - Iphephile kodwa inemikhawulo emandleni ukuze iphephe. | - Iphephe kakhulu, ivumela ukusetshenziswa kwamandla okuphezulu. |
| Ibanga | - Ingaba nebanga elilinganiselwe ngenxa yokuphepha. | - Ibanga elide ngoba lingasebenzisa amandla amaningi ngokuphepha. |
| Ukusebenza Kwesimo Sezulu | - Okuningi kuthintwa ukukhanya kwelanga nesimo sezulu. | - Isebenza kangcono esimweni sezulu esibi futhi ayithinteki kangako ukukhanya kwelanga. |
| Izindleko | - Kushibhile, izingxenye zivame kakhulu. | - Ibiza kakhulu, isebenzisa izingxenye ezikhethekile. |
| Okusetshenziswe Kakhulu Kakhulu | - Izinhlelo zokusebenza ezingabizi kakhulu ezinezidingo ezimaphakathi. | - Ukusetshenziswa okusezingeni eliphezulu njengokushayela okuzenzakalelayo kudinga ibanga elide nokuphepha. |
Ukuqhathanisa phakathi kwezinhlelo ze-1550/1535nm kanye ne-905nm LiDAR kugqamisa izinzuzo ezimbalwa zokusebenzisa ubuchwepheshe be-wavelength ende (1550/1535nm), ikakhulukazi mayelana nokuphepha, ububanzi, nokusebenza ezimweni ezehlukene zemvelo. Lezi zinzuzo zenza izinhlelo ze-1550/1535nm LiDAR zifaneleke ikakhulukazi izinhlelo zokusebenza ezidinga ukunemba okuphezulu nokuthembeka, njengokushayela ukuzimela. Nakhu ukubuka okuningiliziwe kwalezi zinzuzo:
1. Ukuphepha Kwamehlo Okuthuthukisiwe
Inzuzo ebaluleke kakhulu yezinhlelo ze-1550/1535nm LiDAR ukuphepha kwazo okuthuthukisiwe kwamehlo abantu. Amaza amade awela esigabeni esimuncwa kahle kakhulu i-cornea ne-lens yeso, okuvimbela ukukhanya ukuthi kufinyelele kuyi-retina ebucayi. Lesi sici sivumela lezi zinhlelo ukuthi zisebenze kumazinga aphezulu wamandla kuyilapho zihlala ngaphakathi kwemikhawulo yokuchayeka ephephile, zizenze zilungele izinhlelo zokusebenza ezidinga amasistimu e-LiDAR asebenza kahle ngaphandle kokufaka engozini ukuphepha kwabantu.
2. Ibanga elide Lokubona
Ngenxa yekhono lokukhipha amandla aphakeme ngokuphephile, amasistimu we-LiDAR angu-1550/1535nm angafinyelela ibanga elide lokutholwa. Lokhu kubalulekile ezimotweni ezizimele, ezidinga ukubona izinto zikude ukuze zenze izinqumo ngesikhathi. Ububanzi obunwetshiwe obunikezwa yilawa maza wamaza buqinisekisa amandla angcono okulindela nokusabela, okuthuthukisa ukuphepha okuphelele nokusebenza kahle kwamasistimu okuzulazula azimele.
3. Ukusebenza Okuthuthukisiwe Ezimeni Zezulu Ezibi
Amasistimu e-LiDAR asebenza kumaza wamaza angu-1550/1535nm abonisa ukusebenza okungcono ezimweni zezulu ezimbi, njengenkungu, imvula, noma uthuli. Lawa maza amade amade angangena ezinhlayiyeni zasemkhathini ngempumelelo kakhulu kunamaza amaza amafushane, agcine ukusebenza nokwethembeka lapho ukubonakala kungalungile. Leli khono libalulekile ekusebenzeni okungaguquki kwezinhlelo ezizimele, kungakhathaliseki izimo zemvelo.
4. Ukunciphisa Ukuphazamiseka Okuvela Elangeni Nakweminye Imithombo Yokukhanya
Enye inzuzo ye-1550/1535nm LiDAR ukuzwela kwayo okuncishisiwe ekuphazamisekeni okuvela ekukhanyeni okuzungezile, okuhlanganisa ukukhanya kwelanga. Amaza amaza akhethekile asetshenziswa yilezi zinhlelo awavamile emithonjeni yokukhanya yemvelo neyokwenziwa, okunciphisa ubungozi bokuphazamiseka okungathinta ukunemba kwemephu yemvelo ye-LiDAR. Lesi sici sibaluleke kakhulu ezimeni lapho ukutholakala okunembayo nokumepha kubalulekile.
5. Ukungena Okubalulekile
Nakuba kungekona ukucatshangelwa okuyinhloko kwazo zonke izinhlelo zokusebenza, ubude begagasi amade bezinhlelo ze-1550/1535nm LiDAR zinganikeza ukusebenzisana okuhlukile kancane ngezinto ezithile, okungenzeka kunikeze izinzuzo ezimweni ezithile zokusetshenziswa lapho ukukhanya okungena ngama-particle noma izindawo (ngezinga elithile) kungaba yinzuzo. .
Ngaphandle kwalezi zinzuzo, ukukhetha phakathi kwe-1550/1535nm ne-905nm LiDAR izinhlelo kuhlanganisa nokucatshangelwa kwezindleko nezidingo zohlelo lokusebenza. Nakuba izinhlelo ze-1550/1535nm zinikeza ukusebenza nokuphepha okuphakeme, ngokuvamile zibiza kakhulu ngenxa yobunkimbinkimbi nenani eliphansi lokukhiqiza lezingxenye zazo. Ngakho-ke, isinqumo sokusebenzisa ubuchwepheshe be-1550/1535nm LiDAR ngokuvamile sincike ezidingweni ezithile zohlelo lokusebenza, okuhlanganisa ububanzi obudingekayo, ukucatshangelwa kokuphepha, izimo zemvelo, kanye nemikhawulo yesabelomali.
