Whakatauritenga Māmā i waenga i te 905nm me te 1.5μm LiDAR
Me whakamāmā ake, me whakamārama ake te whakataurite i waenga i ngā pūnaha LiDAR 905nm me 1550/1535nm:
| Āhuatanga | 905nm LiDAR | 1550/1535nm LiDAR |
| Haumaru mō ngā Kanohi | - Haumaru ake engari he iti te mana mō te haumaru. | - He tino haumaru, ka taea te whakamahi i te mana nui ake. |
| Awhe | - Kāore e taea te whakamahi i tētahi whānuitanga iti nā te mea he mea haumaru. | - He tawhiti ake te tawhiti nā te mea ka taea te whakamahi i te mana nui ake me te haumaru. |
| Te Mahi i te Huarere | - Ka pāngia nuitia e te rā me te huarere. | - He pai ake te mahi i te rangi kino, ā, kāore i te tino pāngia e te rā. |
| Utu | - He iti ake te utu, he nui ake te kitea o ngā wāhanga. | - He nui ake te utu, ka whakamahia ngā wāhanga motuhake. |
| Pai rawa atu te whakamahi mō | - Ngā tono e aro nui ana ki te utu, engari he taurite ngā hiahia. | - Ko ngā whakamahinga papai pēnei i te taraiwa motuhake me whai tawhiti me te haumaru. |
Mā te whakataurite i waenga i ngā pūnaha LiDAR 1550/1535nm me 905nm ka kitea ētahi painga o te whakamahi i te hangarau roa ake (1550/1535nm), inā koa mō te haumaru, te whānuitanga, me te mahi i roto i ngā āhuatanga taiao rerekē. Nā ēnei painga ka tino pai ngā pūnaha LiDAR 1550/1535nm mō ngā tono e hiahia ana ki te tino tika me te pono, pērā i te taraiwa motuhake. Anei tētahi tirohanga taipitopito ki ēnei painga:
1. Te Haumaru Kanohi Whakapai Ake
Ko te painga nui o ngā pūnaha LiDAR 1550/1535nm ko tō rātou haumaru ake mō ngā kanohi tangata. Ko ngā roangaru roa ka taka ki roto i tētahi kāwai e mimiti pai ake ana e te kornea me te karu o te kanohi, ka ārai i te mārama kia tae atu ki te retina tairongo. Mā tēnei āhuatanga ka taea e ēnei pūnaha te mahi i ngā taumata mana teitei ake me te noho tonu i roto i ngā rohe whakaaturanga haumaru, ka pai ai mō ngā tono e hiahia ana ki ngā pūnaha LiDAR mahi teitei me te kore e whakararu i te haumaru o te tangata.
2. Roa ake te whānuitanga o te kitenga
Nā te kaha ki te tuku i te kaha teitei ake me te haumaru, ka taea e ngā pūnaha LiDAR 1550/1535nm te whakatutuki i te whānuitanga kite roa ake. He mea nui tēnei mō ngā waka motuhake, e hiahia ana ki te kite i ngā mea mai i tawhiti kia taea ai te whakatau i te wā tika. Mā te whānuitanga whānui e whakaratohia ana e ēnei roangaru ka pai ake te āheinga ki te tatari me te urupare, ka whakarei ake i te haumaru me te whai huatanga whānui o ngā pūnaha whakatere motuhake.
3. Te Whakapai Ake i ngā Āhuatanga Huarere Kino
Ko ngā pūnaha LiDAR e mahi ana i ngā roangaru 1550/1535nm e whakaatu ana i te mahi pai ake i roto i ngā āhuatanga huarere kino, pērā i te kohu, te ua, te puehu rānei. Ka taea e ēnei roangaru roa te uru atu ki ngā matūriki o te hau i ngā roangaru poto ake, ka mau tonu te mahi me te pono ina ngoikore te tirohanga. He mea nui tēnei āheinga mō te mahi tonu o ngā pūnaha motuhake, ahakoa ngā āhuatanga taiao.
4. Te Whakaiti i te Whakararuraru mai i te Rā me ētahi atu Pūtake Mārama
Ko tētahi atu painga o te 1550/1535nm LiDAR ko tōna iti o te aro ki te pokanoa mai i te mārama taiao, tae atu ki te rā. Ko ngā roangaru motuhake e whakamahia ana e ēnei pūnaha he iti ake te kitea i roto i ngā puna mārama taiao me ngā puna mārama horihori, e whakaiti ana i te mōrearea o te pokanoa ka pā ki te tika o te mahere taiao a LiDAR. He tino whai hua tēnei āhuatanga i roto i ngā horopaki e tino hiahiatia ana te kimi me te mahere tika.
5. Te Whakaurunga Rauemi
Ahakoa ehara i te mea nui mō ngā tono katoa, ka taea e ngā roangaru roa o ngā pūnaha LiDAR 1550/1535nm te tuku taunekeneke rerekē ki ētahi rauemi, ka puta pea he painga i roto i ngā take whakamahinga motuhake ina whai hua te uru o te mārama mā roto i ngā matūriki, i ngā mata rānei (ki tētahi whānuitanga).
Ahakoa ēnei painga, ko te whiriwhiri i waenga i ngā pūnaha LiDAR 1550/1535nm me te 905nm me whai whakaaro anō hoki ki te utu me ngā whakaritenga tono. Ahakoa he pai ake te mahi me te haumaru o ngā pūnaha 1550/1535nm, he nui ake te utu nā te uaua me te iti o te rahinga whakaputa o ā rātou wāhanga. Nō reira, ko te whakatau ki te whakamahi i te hangarau LiDAR 1550/1535nm ka whakawhirinaki ki ngā hiahia motuhake o te tono, tae atu ki te whānuitanga e hiahiatia ana, ngā whakaaro haumaru, ngā āhuatanga taiao, me ngā here tahua.
