ʻO kahi kūlana kūleʻa o ke kiʻi oblique

1. Manaʻo nui

Ma hope o kekahi mau makahiki o ka hoʻomohala ʻana, i kēia manawa ma Kina, ua hoʻohana ākea ʻia ke kiʻi ʻulaʻula i nā papahana noiʻi cadastral kuaʻāina. Eia nō naʻe, ma muli o ke kaohi o nā pono loea loea, nāwaliwali nā kiʻi oblique no ke ana cadastral o nā hiʻohiʻona nui-hāʻule, ʻo ka mea nui no ka lōʻihi o ka lōʻihi a me ke ʻano kiʻi o nā aniani kāmela oblique i kū ʻole i ka maʻamau. Ma hope o nā makahiki he nui o ka hoʻolālā papahana, ua ʻike mākou aia ma loko o 5 knm ka pololei o ka palapala ʻāina, a laila aia ka GSD ma loko o 2 knm, a maikaʻi loa ke ʻano 3D, pono a pololei nā kihi o ka hale.

ʻO ka maʻamau, ʻo ka lōʻihi o ka pahupaʻiwikiō i hoʻohana ʻia no nā papahana ana cadastral kuaʻāina ʻo 25mm i ka pae a me ka 35mm oblique. I mea e hoʻokō ai i ka pololei o 1: 500, pono ka GSD ma waena o 2 cm. A e hōʻoia i kēlā, ʻo ke kiʻekiʻe lele o nā drones aia ma waena o 70m-100m. Wahi a kēia kiʻekiʻe lele, ʻaʻohe ala e hoʻopau ai i ka hōʻiliʻili ʻikepili o nā hale he 100m ma luna. ʻOiai inā ʻoe e holo ana i kahi lele, ʻaʻole hiki iā ia ke hōʻoia i ka uhi o nā kaupaku, a laila maikaʻi ʻole ke ʻano o ke k modelkohu. .A no ka haʻahaʻa loa o ke kiʻekiʻe o ka hakakā, weliweli loa ia no UAV.

I mea e hoʻonā ai i kēia pilikia, i ka Mei 2019, ua hoʻokō mākou i ka hōʻike hōʻoia ʻoiaʻiʻo o ka Oblique Photography no nā hale kiʻekiʻe kiʻekiʻe o ke kūlanakauhale. ʻO ke kumu o kēia hoʻāʻo e hōʻoia inā ʻo ka pololei palapala ʻāina o ke k 3Dkohu 3D i kūkulu ʻia e RIY-DG4pros pahupaʻiwikiō hiki ke hoʻokō i ke koi o 5 cm RMSE.

5. Panina

I kēia hoʻāʻo, ʻo ka paʻakikī, ʻo ia ke kulu kiʻekiʻe a haʻahaʻa hoʻi o ka hanana, ke kiʻekiʻena kiʻekiʻe o ka hale a me ka papa hana paʻakikī. ʻO kēia mau mea e alakaʻi i ka hoʻonui ʻana i ka paʻakikī o ka lele, kahi kiʻekiʻe kiʻekiʻe, a me kahi hiʻohiʻona 3D ʻoi aku ka maikaʻi, e alakaʻi ai i ka hōʻemi o ka pololei i ka nānā cadastral.

Ma muli o ka lōʻihi o ka lōʻihi o ke kikowaena RIY-DG4pros ma mua o nā kāmela oblique maʻamau, e hōʻoia ia e hiki i kā mākou UAV ke lele i kahi kiʻekiʻe palekana, a ʻo ka hoʻonā kiʻi o nā mea lepo i loko o 2 cm. I ka manawa like, hiki i ke aniani piha ke kōkua iā mākou e hopu i nā kihi hou aku o nā hale ke lele ana i nā wahi hale kiʻekiʻe, no laila e hoʻomaikaʻi ana i ka maikaʻi o ka hiʻohiʻona 3D. Ma lalo o ka manaʻo e hōʻoiaʻiʻo ʻia nā hāmeʻa pono lakohana, hoʻomaikaʻi mākou i ka uhi o ka lele a me ka mahele o ka mahele o nā kiko kaohi e hōʻoia i ka pololei o ka hiʻohiʻona 3D.

kiʻi kiʻi oblique no nā wahi kiʻekiʻe o ke ana cadastral, hoʻokahi manawa no ka palena o nā pono hana a me ka ʻike ʻole, hiki ke ana ʻia ma o nā hana kuʻuna. Akā ka hopena o nā hale kiʻekiʻe ma ka hōʻailona RTK ke kumu hoʻi i ka paʻakikī a me ka maikaʻi ʻole o ke ana ʻana. Inā hiki iā mākou ke hoʻohana iā UAV e hōʻiliʻili i ka ʻikepili, hiki ke hoʻopau loa ʻia ka mana o nā hōʻailona ukali, a hiki ke hoʻomaikaʻi maikaʻi ʻia ke kaulike o ke ana ʻana. No laila, he mea nui ka kūleʻa o kēia hōʻike iā mākou.

Hōʻike kēia hōʻike e hiki i ka RIY-DG4pros ke kāohi i ka RMS i kahi liʻiliʻi o ka waiwai, loaʻa ka maikaʻi o ka hoʻohālikelike 3D, a hiki ke hoʻohana ʻia i nā papahana ana pono o nā hale kiʻekiʻe.
