Miyeso Yachilungamo pa Kafukufuku wa LiDAR: Zomwe Manambalawa Amatanthauza
Lipotoli likanena kuti kafukufuku wa LiDAR ali ndi kulondola kwa m’mwamba (vertical accuracy) kwa masentimita awiri, kodi zimenezi zikutanthauza chiyani kwenikweni ku pulojekiti yanu? Kumvetsa miyeso yolondola kumapangitsa kusiyana pakati pounika mtengo moyenera komanso kusasocheretsedwa ndi manambala otsatsa malonda chabe.
Kulondola mu LiDAR sikutanthauza nambala imodzi yokha. Kumaphatikiza kulondola m’mwamba, kulondola m’mbali, ndi muyeso wa ziwerengero wotchedwa RMSE, zomwe pamodzi zimaonetsa kudalirika kwenikweni kwa deta.
Onani momwe RMSE imapangidwira kuchokera ku madontho omwazika
Kuwona kwa RMSE Pomwepo
Onani momwe cholakwika chimakhudzira RMSE
Kowerengera kwa RMSE Kothandizana
Tsimikizirani kulondola ndi malo oyezera pansi
Dinani malo oyezera kuti muyerekeze
Miyeso Itatu Yofunika Kwambiri Kudziwa
Kulondola M’mwamba (Vertical Accuracy)
Momwe msinkhu wochokera ku LiDAR umagwirizanirana ndi msinkhu weniweni wa nthaka, wofunikira kwambiri pa ntchito za nthaka.
Kulondola M’mbali (Horizontal Accuracy)
Momwe malo a X ndi Y a dontho lililonse amagwirizanirana ndi malo ake enieni pa mapu.
RMSE (Root Mean Square Error)
Chidule cha ziwerengero chomwe chimasonyeza momwe miyeso yoyezedwa imasokerera pafupifupi kuchokera kumalo odziwika oyezera.
Kutsimikizira Malo Oyezera (Checkpoint Verification)
Malo owongolera pansi oyezedwa padera amafanizidwa ndi deta ya LiDAR kuti awerengere kulondola kwenikweni.
Lipoti la Chidaliro
Lipoti loyenera limafotokoza njira yomwe yagwiritsidwa ntchito komanso kuchuluka kwa malo oyezera omwe agwiritsidwa ntchito.
| Muyeso | Zomwe Zimakuuzani |
|---|---|
| RMSE ya M’mwamba | Cholakwika cha msinkhu poyerekeza ndi malo odziwika |
| RMSE ya M’mbali | Cholakwika cha malo pa X ndi Y |
| Kuchuluka kwa Madontho (Point Density) | Kuchuluka kwa tsatanetsatane wa nthaka womwe wajambulidwa |
Nambala yolondola yopanda njira yotsimikizira ilibe tanthauzo lililonse. Funsani nthawi zonse malo angati oyezera odziyimira pawokha omwe agwiritsidwa ntchito komanso komwe anali.
Kulondola sikunena pamapepala otsatsa malonda. Ndi nambala yotsimikiziridwa kudzera m’malo odziyimira pawokha oyezera.
Kupeza Kulondola Kotsimikizika pa Pulojekiti Yanu
Kumvetsetsa miyesoyi kumakuthandizani kuunika mtengo uliwonse mwanzeru. Gulu lathu la drone survey limalemba njira ya malo oyezera pa pulojekiti iliyonse ya LiDAR scan.
Kodi mukufuna lipoti la kafukufuku wokhala ndi kulondola kotsimikizika?
Funsani za njira yathu yoyezera musanayambe pulojekiti yanu yotsatira ya LiDAR.
Mafunso Ofunsidwa Kawirikawiri (FAQ)
RMSE imatanthawuza Root Mean Square Error, muyeso wa ziwerengero womwe umafotokoza mwachidule momwe deta yoyezedwa imasiyanirana ndi malo enieni a pansi.
M’mwamba mumayeza kulondola kwa msinkhu (Z), pomwe m’mbali mumayeza malo pa mapu (X ndi Y).
Malo oyezera amayezedwa padera kuti atsimikizire kulondola kwenikweni pamtunda m’malo modalira malingaliro chabe.
Ndi kayendetsedwe koyenera ka pansi, makina amakono a drone LiDAR amakwaniritsa masentimita 2 mpaka 5 akulondola m’mwamba.
Masentimita 2 mpaka 4 amatengedwa ngati mulingo wapamwamba kwambiri wofufuzira misewu ndi ma drone LiDAR.
Sikulimbikitsidwa; zonena zopanda deta yotsimikizira sizingatsimikizidwe, pemphani lipoti la malo oyezera nthawi zonse.
Zimatengera kukula ndi mtundu wa malo, ndikugawa koyenera m’dera lonselo la pulojekiti.
Kuchuluka kwakukulu kumawonjezera tsatanetsatane koma popanda kusamalira pansi sikutsimikizira kulondola kwathunthu.
Chizindikiro chofooka cha GPS, kuchepa kwa malo oyezera pansi, mitengo yambiri yowundana, ndi msinkhu wolakwika wowulukira.
Ayi, pakhoza kukhala kusiyana pang'ono malinga ndi kuterera kwa malo, kuchuluka kwa zomera, ndi mtunda wochokera kumalo oyendetsera.
Nambalayi ndi ya mafunso okhudza mapulojekiti okha. Chonde musalumikizane nafe pa nkhani za maphunziro kapena ntchito.
