Ukuhlukaniswa Kwefu Lamaphuzu le-LiDAR Kuchazwe Kalula
Ifu lamaphuzu le-LiDAR elingahlungiwe (raw) liqukethe izigidi zamaphuzu endaweni ye-3D, lapho iphuzu ngalinye linezixhumanisi ze-X, Y, Z kuphela ngaphandle kolwazi lokuthi limele ini. Ukuhlukanisa (Classification) kuyinqubo ebalulekile eguqula le datha engahlelekile ibe yizigaba zobunjiniyela ezinengqondo: umhlaba wangempela, izitshalo, izakhiwo, izintambo zikagesi nezinye izakhiwo.
Ngaphandle kokuhlukaniswa okufanele, ifu lamaphuzu alikwazi ukusetshenziselwa imisebenzi yobunjiniyela. Isoftware ayikwazi ukwakha imodeli yezwe yedijithali (DTM), ukubala umthamo womhlabathi noma ukudweba imigqa ye-contour kuze kube yilapho ibona ngokunembile ukuthi yimaphi amaphuzu angumhlaba wangempela.
Buka Inqubo Yokuhlukanisa Ngesikhathi Sangempela
Ukulingisa Ukuskena Kokuhlukanisa
Zama Ukuhlukanisa Amaphuzu Ngokwakho
Ukuzijwayeza Ukuhlukanisa Amaphuzu
Lungisa Umkhawulo Wokuphakama Komhlaba
Isihlungi Somkhawulo Wokuphakama
Isebenza Kanjani Ngempela Inqubo Yokuhlukanisa
Ukulayishwa kwedatha engahlungiwe
Ifu lamaphuzu elingahlukanisiwe lifakwa nezixhumanisi ze-3D, amandla nenombolo yokubuyela.
I-algorithm yokuhlunga umhlaba
Ama-algorithms athuthukile afana ne-Progressive TIN densification abona indawo ephansi eqhubekayo njengomhlaba.
Ukubalwa kokuphakama phezu komhlaba
Ukuphakama okuqondile kwephuzu ngalinye elisele kubalwa ngokunembile uma kuqhathaniswa nomhlaba ohlonziwe.
Ukwabiwa kwezigaba
Amaphuzu ahlukaniswa abe ngamazinga okuphakama kwezitshalo, izakhiwo noma ezinye izigaba.
Ukubuyekezwa kwekhwalithi ngesandla
Usonjiniyela onekhono uhlola futhi alungise amaphuzu ahlukaniswe kabi ezinsikeni zezakhiwo nasemithambekeni.
Izinhlelo ezijwayelekile zokuhlukanisa ze-LiDAR zisebenzisa amakhodi ezinombolo ze-LAS: Isigaba 2 simele Umhlaba (Ground), Isigaba 3 kuya ku-5 simele izitshalo ezimfushane, eziphakathi nezinde, kanti Isigaba 6 simele Izakhiwo.
Ifu lamaphuzu elingahlukanisiwe liwumsindo onezixhumanisi kuphela. Ukuhlukanisa yikho okwenza libe yimephu yobunjiniyela yangempela.
Kungani Lesi Sigaba Sibalulekile Ephrojektini Yakho
Ukuhlukaniswa okunembile kunquma ngokuqondile ikhwalithi yayo yonke imiphumela, kusukela kumamephu e-contour kuya ekubalweni komthamo womhlaba. Ithimba lethu le-drone survey lihlanganisa ukucubungula okuzenzakalelayo nokubuyekezwa kochwepheshe kuyo yonke iphrojekthi ye-LiDAR scan.
Ingabe udinga idatha ye-LiDAR ehlukaniswe ngokunembile?
Sitshele ngohlobo lwephrojekthi yakho futhi sizochaza inqubo yethu yokuhlukanisa nokuqinisekisa ikhwalithi.
Imibuzo Evame Ukubuzwa
Yinqubo yokuhlunga amaphuzu e-laser e-3D abe yizigaba eziwusizo njengomhlabathi, izitshalo nezakhiwo ngokusebenzisa ukuhlaziywa kokuphakama.
Ngaphandle kokuhlukanisa, isoftware ayikwazi ukuhlukanisa umhlaba ezihlahleni noma ezakhiweni, okwenza ukwakhiwa kwe-DTM kungenzeki.
I-LAS yifomethi yefayela le-binary evamile yamazwe ngamazwe yokugcina idatha ye-point cloud ye-3D enamakhodi okuhlukanisa ku-GIS naku-CAD.
Iningi lenziwa ngama-algorithms, kodwa ukubuyekezwa ngesandla kochwepheshe kubalulekile emingceleni eyinkimbinkimbi.
Kuyindawo yezwe yedijithali eyakhiwe kuphela ngamaphuzu omhlaba, kususwe zonke izitshalo nezakhiwo.
Ubeka umngcele phakathi komhlaba notshani obufushane; ukusetha okungalungile kungahlanekezela isimo somhlaba.
Umhlaba, izitshalo ezimfushane, eziphakathi, ezinde, izakhiwo nezintambo zikagesi.
Yebo, aphazamisa imigqa ye-contour nokubalwa komthamo, yingakho ukubuyekezwa kwekhwalithi kubalulekile.
I-algorithm evamile yokuhlunga umhlaba eyakha amanethiwekhi onxantathu ukuze ibone amaphuzu aphansi njengomhlaba.
Kuncike kubukhulu bendawo kanye nokuminyana kwezitshalo, kodwa ukuhlanganiswa kwezinhlelo kuqinisekisa ukunemba okuphezulu.
Le nombolo ibekelwe imibuzo yamaphrojekthi ebhizinisi kuphela. Sicela ungaxhumani nathi mayelana nokuqeqeshwa noma imisebenzi.
