Kupu Whakataki
Mai i te mutunga o te tekau tau atu i 1960 me te tīmatanga o te tekau tau atu i 1970, kua whakakapia te nuinga o ngā pūnaha whakaahua rangi tuku iho e ngā pūnaha pūoko hiko-whatu me te hikohiko rererangi me te rererangi. Ahakoa e mahi ana te whakaahua rangi tuku iho i roto i te roangaru mārama-kitea, ka whakaputahia e ngā pūnaha pūoko mamao rererangi me te whenua hou ngā raraunga matihiko e kapi ana i te mārama kitea, te pūwhero whakaata, te pūwhero wera, me ngā rohe hihi ngaruiti. He whai hua tonu ngā tikanga whakamārama tirohanga tuku iho i roto i te whakaahua rangi. Heoi anō, he whānui ake ngā tono o te pūoko mamao, tae atu ki ngā mahi tāpiri pēnei i te whakatauira ariā o ngā āhuatanga ūnga, ngā ine hihi o ngā mea, me te tātari whakaahua matihiko mō te tango mōhiohio.
Ko te pūoko mamao, e pā ana ki ngā āhuatanga katoa o ngā tikanga kimi tawhiti kore-pā, he tikanga e whakamahi ana i te hiko aukume hei kimi, hei tuhi me te ine i ngā āhuatanga o tētahi ūnga, ā, i tuatahitia te whakamāramatanga i te tekau tau atu i 1950. Mō te mara o te pūoko mamao me te mahere, e rua ngā momo pūoko: te pūoko hohe me te pūoko kore, ā, he pūoko hohe te pūoko Lidar, ka taea te whakamahi i tōna ake pūngao hei tuku mārama ki te ūnga me te kimi i te mārama e whakaatahia ana mai i a ia.
Te Pūrongo me te Whakamahinga o te Lidar Kaha
Ko te Lidar (te kimi me te hora i te mārama) he hangarau e ine ana i te tawhiti i runga i te wā e tukuna ana, e whiwhi ana hoki i ngā tohu taiaho. I ētahi wā ka whakamahia te Airborne LiDAR hei taurite ki te matawai taiaho rererangi, te mahere, te LiDAR rānei.
He tūtohi rere noa tēnei e whakaatu ana i ngā mahi matua o te tukatuka raraunga pūwāhi i te wā e whakamahia ana te LiDAR. Whai muri i te kohikohi i ngā taunga (x, y, z), mā te whakarōpū i ēnei pūwāhi ka taea te whakapai ake i te whai huatanga o te whakaputa me te tukatuka raraunga. Haunga te tukatuka āhuahanga o ngā pūwāhi LiDAR, he mea whai hua anō hoki ngā mōhiohio kaha mai i te urupare LiDAR.
I roto i ngā tono katoa o te pūoko mamao me te mahere whenua, he painga motuhake tō LiDAR, arā, ko te whiwhi i ngā inenga tika ake, ahakoa te pānga o te rā me ētahi atu pānga o te rangi. E rua ngā wāhanga o tētahi pūnaha pūoko mamao noa, he ine tawhiti laser me tētahi pūoko ine mō te tūnga, ka taea te ine tika i te taiao matawhenua i roto i te 3D me te kore he whakapōturi āhuahanga nā te mea kāore he whakaahua e uru ana (ka whakaahuahia te ao 3D i roto i te papa 2D).
