Jinsi pointi za udhibiti na data ya PPK huathiri usahihi wa kiasi wa muundo wa 3D

Katika majaribio haya mawili, tulianzisha vigeu vinne tofauti ili kuthibitisha usahihi jamaa wa muundo wa 3D. Vigezo vinne tofauti ni:

1: Aina za ndege zisizo na rubani:Drone ya VTOL au drone yenye rota nyingi

2:GSD tofauti

3:Pamoja na/Bila pointi za udhibiti wa ardhini

4:Pamoja na/Bila data ya PPK

Jaribio la 1: athari za pointi za udhibiti wa ardhi (GCPs) kwenye usahihi wa jamaa wa mfano wa 3D;

Hitimisho

Vigezo vya majaribio 1 ni:

1:Pamoja na/Bila data ya PPK.

2:Aina za ndege zisizo na rubani :drone ya VTOL au drone yenye rota nyingi

3:GSD tofauti: 1.5 cm au 2cm

Baada ya uchambuzi wa seti tano za data ya majaribio, tunaweza kufikia hitimisho zifuatazo:

Wakati kamera ya oblique ni DG4Pros:

(1) Ikiwa na/Bila sehemu ya udhibiti wa ardhini (GCP) inayohusika katika utatuzi wa AT, iwe VTOL au ndege isiyo na rubani yenye rota nyingi, iwe GSD ni 2cm au 1.5cm, muundo wa 3D uliojengwa na kamera ya oblique DG4Pros unaweza kukutana na mahitaji ya kosa la usahihi wa kiasi Ds≤10cm.

(2) Wakati na/bila GCP ni kigezo kimoja, usahihi wa jamaa wa muundo wa 3D na GCPs ni bora kuliko ule bila GCP.

(3) Wakati GSD ni kigezo kimoja, usahihi wa jamaa wa muundo wa 3D ambao GSD 1.5cm ni bora kuliko hiyo GSD 2cm.

(4) Wakati drone ya mtoa huduma ni kigezo kimoja, usahihi wa jamaa wa muundo wa 3D ambao kutumia rota nyingi ni bora kuliko ule wa kutumia VTOL kama drone ya kubeba.

Jaribio la 2:Bila GCPs, athari ya data ya PPK kwenye usahihi wa jamaa wa muundo wa 3D
