Uthelekiso olulula phakathi kwe-905nm kunye ne-1.5μm LiDAR
Masenze lula kwaye sicacise uthelekiso phakathi kwe-905nm kunye ne-1550/1535nm iinkqubo zeLiDAR:
| Uphawu | 905nm LiDAR | 1550/1535nm LiDAR |
| Ukhuseleko lwamehlo | - Ikhuselekile kodwa inemida kumandla okhuseleko. | -Ikhuselekile kakhulu, ivumela ukusetyenziswa kwamandla aphezulu. |
| Uluhlu | -Inokuba noluhlu olulinganiselweyo ngenxa yokhuseleko. | -Uluhlu olude kuba lunokusebenzisa amandla amaninzi ngokukhuselekileyo. |
| Ukusebenza kwiMozulu | - Ichatshazelwa ngakumbi kukukhanya kwelanga kunye nemozulu. | - Isebenza ngcono kwimozulu embi kwaye ayichatshazelwa kangako kukukhanya kwelanga. |
| Iindleko | - Ixabiso eliphantsi, amacandelo axhaphake kakhulu. | - Ibiza kakhulu, isebenzisa amacandelo akhethekileyo. |
| Eyona iSetyenziselweyo | - Izicelo ezingabizi kakhulu kunye neemfuno eziphakathi. | -Usetyenziso olukwinqanaba eliphezulu njengokuqhuba ngokuzimeleyo kufuna umgama omde kunye nokhuseleko. |
Ukuthelekisa phakathi kwe-1550 / 1535nm kunye ne-905nm ye-LiDAR iinkqubo zigxininisa iingenelo ezininzi zokusebenzisa ubude be-wavelength (1550 / 1535nm) ubuchwepheshe, ngokukodwa malunga nokhuseleko, uluhlu, kunye nokusebenza kwiimeko ezahlukeneyo zokusingqongileyo.Ezi zibonelelo zenza iinkqubo ze-1550/1535nm ze-LiDAR zifaneleke ngokukodwa kwizicelo ezifuna ukuchaneka okuphezulu kunye nokuthembeka, njengokuqhuba ngokuzimeleyo.Nalu ujongo olunzulu kwezi zibonelelo:
1. Ukhuseleko lwamehlo olongezelelweyo
Olona ncedo lubalulekileyo lweenkqubo ze-1550/1535nm LiDAR lukhuseleko lwazo lwamehlo abantu.Ubude bamaza amade buwela kudidi olufunxwa kakuhle ngakumbi yi-cornea kunye ne-lens yeliso, luthintela ukukhanya ekufikeleleni kwi-retina ebuthathaka.Olu phawu luvumela ezi nkqubo ukuba zisebenze kumanqanaba aphezulu ombane ngelixa zihlala ngaphakathi kwemida ekhuselekileyo yokuvezwa, zizenza zilungele izicelo ezifuna iinkqubo eziphezulu ze-LiDAR ngaphandle kokubeka esichengeni ukhuseleko lomntu.
2. Uluhlu olude lokuFumana
Ngombulelo kubuchule bokukhupha kumandla aphezulu ngokukhuselekileyo, iinkqubo ze-1550/1535nm zeLiDAR zinokufikelela kuluhlu olude lokubona.Oku kubalulekile kwiimoto ezizimeleyo, ezifuna ukubona izinto zisekude ukwenza izigqibo ngexesha.Uluhlu olwandisiweyo olubonelelwa ngala maza obude luqinisekisa ulindelo olungcono kunye namandla okuphendula, ukunyusa ukhuseleko olupheleleyo kunye nokusebenza kakuhle kweenkqubo zokuhamba ezizimeleyo.
3. Ukuphuculwa koMsebenzi kwiiMeko zeMozulu eziMandundu
Iinkqubo ze-LiDAR ezisebenza kwi-1550/1535nm wavelengths zibonisa ukusebenza okungcono kwiimeko zemozulu ezimbi, njengenkungu, imvula, okanye uthuli.La maza amade amade anokungena kwiincinci ze-atmospheric ngokusebenzayo ngakumbi kunobude obufutshane obufutshane, ukugcina ukusebenza kunye nokuthembeka xa ukubonakala kungalunganga.Esi sikhundla siyimfuneko ekusebenzeni okuhambelanayo kweenkqubo ezizimeleyo, kungakhathaliseki ukuba iimeko zokusingqongileyo.
4. UkuNcitshiswa kokuphazamiseka kokuKhanya kweLanga kunye neminye imithombo yokukhanya
Enye inzuzo ye-1550/1535nm LiDAR kukuncitshiswa kwayo uvakalelo ekuphazamiseni ukukhanya okukhoyo, kubandakanya nokukhanya kwelanga.Ubude obuthile obusetyenziswa zezi nkqubo aziqhelekanga kwimithombo yokukhanya yendalo kunye neyenziweyo, enciphisa umngcipheko wokuphazamiseka okunokuchaphazela ukuchaneka kwemephu yendalo ye-LiDAR.Olu phawu lubaluleke kakhulu kwiimeko apho ukuchongwa okuchanekileyo kunye nokwenza imephu kubaluleke kakhulu.
5. Ukungena kwezinto
Ngelixa ingeyiyo eyona ngqwalasela ephambili kuzo zonke izicelo, ubude bexesha elide be-1550/1535nm yeenkqubo zeLiDAR zinokubonelela ngonxibelelwano olwahlukileyo kancinci kunye nezinto ezithile, ezinokuthi zibonelele ngeenzuzo kwiimeko ezithile zokusetyenziswa apho ukukhanya okungenayo kusetyenziswa iinxalenye okanye umphezulu (ukusa kwinqanaba elithile) kunokuba luncedo. .
Ngaphandle kwezi nzuzo, ukhetho phakathi kwe-1550 / 1535nm kunye ne-905nm ye-LiDAR iinkqubo nazo zibandakanya ukuqwalaselwa kweendleko kunye neemfuno zesicelo.Ngelixa iinkqubo ze-1550 / 1535nm zibonelela ngokusebenza okuphezulu kunye nokhuseleko, ngokuqhelekileyo zibiza kakhulu ngenxa yobunzima kunye nomthamo ophantsi wemveliso yamacandelo abo.Ngoko ke, isigqibo sokusebenzisa iteknoloji ye-1550 / 1535nm ye-LiDAR ihlala ixhomekeke kwiimfuno ezithile zesicelo, kubandakanywa noluhlu olufunekayo, ukuqwalaselwa kokhuseleko, iimeko zokusingqongileyo, kunye nemiqobo yebhajethi.
