Ukulanda idatha

Icala lempumelelo lokuthwebula izithombe nge-oblique

—Sebenzisa imodeli ye-3D ukwenza ucwaningo lwe-cadastral ezindaweni eziphakeme kakhulu

1. Ukubuka konke

Ngemuva kweminyaka eminingana yentuthuko, manje eseChina, ukuthwebula izithombe kwe-oblique kuye kwasetshenziswa kabanzi kumaphrojekthi wokuhlola asezindaweni zasemakhaya. Kodwa-ke, ngenxa yokuvinjelwa kwemibandela yezobuchwepheshe bemishini, izithombe ze-oblique zisabuthakathaka ekulinganisweni kwe-cadastral kwezigcawu ezinkulu, ikakhulukazi ngoba ubude begama kanye nefomethi yesithombe selensi yekhamera ye-oblique ayikho ezingeni elifanele. Ngemuva kweminyaka eminingi yesipiliyoni sephrojekthi, sithole ukuthi ukunemba kwemephu kufanele kube phakathi kuka-5 cm, khona-ke i-GSD kumele ibe phakathi kuka-2 cm, futhi imodeli ye-3D kufanele ibe yinhle kakhulu, emaphethelweni esakhiwo kufanele aqonde futhi acace.


Ngokuvamile, ubude obugxile kwikhamera obusetshenziselwa amaphrojekthi wokulinganisa asezindaweni zasemakhaya ngu-25mm ngokuma mpo no-35mm oblique. Ukuze kuzuzwe ukunemba kwe-1: 500, i-GSD kumele ibe ngaphakathi kuka-2 cm. Futhi ukuqinisekisa ukuthi, ukuphakama kwendiza kwama-drones ngokuvamile kuphakathi kuka-70m-100m. Ngokwalokhu ukuphakama kwendiza, ayikho indlela yokuqedela ukuqoqwa kwedatha yezakhiwo eziyi-100m-ngenhla.Ngisho noma wenza indiza noma kunjalo, ayikwazi ukuqinisekisa ukugqagqana kophahla, okuholela ezingeni elibi lemodeli Futhi ngoba ubude bokulwa buphansi kakhulu, kuyingozi enkulu kwi-UAV.

Ukuze sixazulule le nkinga, ngoMeyi 2019, senze isivivinyo sokuqinisekisa ukunemba kwe-Oblique Photography yezakhiwo eziphakeme ezisemadolobheni. Inhloso yalolu vivinyo ukuqinisekisa ukuthi ukunemba kokugcina kwemephu yemodeli ye-3D eyakhiwe yi-RIY-DG4pros oblique camera kungahlangabezana nemfuneko ye-5 cm RMSE.
