I roto i te hangarau pūoko hou, ko te LiDAR (Light Detection and Ranging) te "kanohi" o ngā mīhini, e kite tika ana i te ao 3D mā te tuku me te whiwhi i ngā hihi laser. Me whai "arotahi tiaki" mārama ēnei "kanohi" hei tiaki - koinei te Taupoki Matapihi LiDAR. Ehara i te mea he karāhe noa iho engari he wāhanga hangarau teitei e whakauru ana i te pūtaiao rauemi, te hoahoa whatu, me te hangarau tika. Ko tana mahi e whakatau tika ana i te tika o te pūoko, te whānuitanga, me te pono whānui o ngā pūnaha LiDAR.

Matapihi Whatu 1

I. Ngā Mahi Matua: Kei tua atu i te "Tiakitanga"
Ko te taupoki matapihi LiDAR he ārai whatu papatahi, porowhita rānei e takai ana i te wāhanga o waho o te pūoko LiDAR. Ko ōna mahi matua ko:

1. Te Tiakitanga Tinana:Ka wehea pai te puehu, te makuku, te hinu, tae atu ki ngā paru e rere ana, ā, ka tiakina ngā wāhanga o roto (hei tauira, ngā kaiwhakaputa taiaho, ngā pūoko, ngā whakaata matawai).
2. Te Hiritanga Taiao:Hei wāhanga o te whare, ka hangaia he hiri ārai-hau me ngā wāhanga hanganga hei whakatutuki i ngā whakatauranga IP e hiahiatia ana (hei tauira, IP6K7/IP6K9K), kia mau ai te mahi i roto i ngā āhuatanga kino pēnei i te ua, te hukarere, me ngā awha onepu.
3. Tukunga Whatu:Ko tāna mahi tino nui ko te tuku i ngā taiaho roa-ngaru motuhake kia tika te haere mā roto me te iti o te hē. Mā te aukati, te whakaata, te hapa rānei ka whakaiti tika i te tika o te whānuitanga me te kounga o te kapua pūwāhi.

II. Ngā Rauemi Matua: Te Pakanga o ngā Mōhiti'
Ko te whiriwhiri rauemi te mea e whakatau ana i te kounga o ngā uhi matapihi. Ko te umanga matua e whakamahi ana i ngā rauemi karāhe, e rua ngā momo matua:
1. Karāhe Hiraka Whakakotahi

• Ngā Āhuatanga:Ko te mea tino rongonui mō ngā mahi motuka me ngā mahi ahumahi. He mea hanga ki te silica tino parakore, ā, he tino pai ngā āhuatanga whatu.

• Ngā Painga:

1. He tino pai te whakawhiti mai i te UV ki te IR me te tino iti o te mimiti.
2. Ka taea e te tauwehenga whānui wera iti te tu atu i ngā pāmahana tino kino (-60°C ki te +200°C) me te kore e rerekē te āhua.
3. He tino mārō (Mohs ~7), ātete ki te mirimiri mai i te onepu/hau.

• Ngā tono:Ngā waka motuhake, ngā AGV ahumahi papai, te ruri i te LiDAR.

2. Karāhe Hapaira

• Ngā Āhuatanga:He α-alumina tioata-kotahi hangai, e tohu ana i te mahi tino-tiketike.

• Ngā Painga:

1. Tino mārō (Mohs ~9, tuarua ki te taimana), tata kore e rakuraku.
2. Te whakawhiti whatu taurite, te ātete pāmahana teitei (ira rewa ~2040°C), me te pumau matū.

• Ngā Wero:He nui te utu, he uaua te tukatuka (me whakamahi ngā mea whakakoi taimana), ā, he nui te kiato.
• 'Ngā tono:Ngā inenga tino tika mō te ope taua, te rererangi, me ngā mahi ine tino tika.

III. Paninga: Te Hangarau Matua e Huri ai te Kōhatu hei Koura​​

Ahakoa te papa, he mea nui ngā paninga hei whakatutuki i ngā tono whatu pakari a LiDAR:

• 'Paninga Ārai-Whakaata (AR):Ko te paparanga tino hira. Ka whakatakotoria mā te paninga korehau (hei tauira, te mimiti hiko, te pupuhi magnetron), ka whakaitihia te whakaata o te mata ki te <0.5% i ngā roangaru ūnga, ka whakanui ake i te tuku mai i te ~92% ki te >99.5%.
• Paninga Wai-ātete/Oleophobic:Ārai i te piri o te wai/hinu, kia mārama ai i roto i te ua, i ngā taiao poke rānei.
• 'Ētahi atu Paninga Mahi:Ngā kiriata tango kohu wera (mā te whakamahi i te ITO), ngā paparanga ārai-pūmau, me ētahi atu, mō ngā hiahia motuhake.

IV. Ngā Tawhā Mahi Matua

I te wā e whiriwhiri ana, e aromatawai ana rānei i tētahi taupoki matapihi LiDAR, arotahi ki ēnei inenga:

1. Tukunga @ Roangaru Whāinga:Te ōrau o te mārama e tukuna ana i te roangaru mahi a te LiDAR (hei tauira, >96% i te 905nm/1550nm i muri i te paninga AR).
2. Hototahi o te Rōpū Pūoro:Me ōrite ki ngā roangaru taiaho (905nm/1550nm); me whakaiti te whakaata (<0.5%).
3. Te Tika o te Pikitia Mata:Me ≤λ/4 (λ = te roangaru taiaho) ngā hapa papatahi me te whakarara hei karo i te hē o te hihi.
4. 'Te Pakari me te Ātete ki te Mau:I inehia ki te tauine Mohs; he mea nui mō te roa o te mau.
5. Te Manawanui Taiao:

• Ātete wai/pūehu: He iti rawa te whakatauranga IP6K7.
• Huringa pāmahana: Ko te awhe mahi i te nuinga o te wā -40°C ki te +85°C.
• Ātete ki te rehu UV/tote hei ārai i te pirau.

V. Ngā Horopaki Taupānga

Tata ki ngā pūnaha LiDAR katoa e pāngia ana e te taiao e hiahia ana ki ngā taupoki matapihi:

• Ngā Waka Motuhake:Ka whakairihia ki runga i ngā tuanui, i ngā parepare, i ngā taha rānei, me te anga atu ki te pānga tika ki te huarere me te hihi UV.
• ​​Ngā Pūnaha Āwhina Taraiwa Matatau (ADAS):Kua whakauruhia ki roto i ngā tinana o te waka, e hiahia ana ki te āhua ataahua.
• ​​Ngā AGV/AMR Ahumahi:Te mahi i roto i ngā whare putunga/wheketere me te mōrearea o te puehu me te tukinga.
• ​​Te Ruri me te Pūrongo Mamao:Ko ngā pūnaha rererangi/e mau ana ki te waka ka tū pakari ki ngā huringa teitei me ngā piki me ngā heke o te pāmahana.

Whakamutunga'

Ahakoa he wāhanga ā-tinana māmā noa iho, he mea nui te taupoki matapihi LiDAR hei whakarite i te "tirohanga" mārama me te pono mō LiDAR. Ko tōna whanaketanga e whakawhirinaki ana ki te whakaurunga hohonu o te pūtaiao rauemi, te whatu, ngā tukanga paninga, me te hangarau taiao. I te whanaketanga o te wā o te taraiwa motuhake, ka haere tonu te whanaketanga o tēnei "matapihi", hei tiaki i te tirohanga tika mō ngā mīhini.
