Hoe GSD- en drager-dronetypen beynfloedzje de relative krektens fan 3D-model

Yn it lêste artikel Hoe grûnkontrôlepunten en PPK-gegevens de relative krektens fan 3D-model beynfloedzje, hawwe wy neamd dat neist GCP's en PPK-gegevens, de GSD en dragerdrone ek in bepaalde graad fan effekten hawwe op 'e relative krektens fan 'e 3D model.Sa dogge wy in oare test om it te ferifiearjen.

Eksperimint 1: it effekt fan GSD op 'e relative krektens fan it 3D-model;

Konklúzjes

De fariabelen fan eksperimint 1 binne:

1: Mei/Sûnder PPK-gegevens.

2: Mei/Sûnder GCP's.

3: ferskillende GSD: 1,5 sm of 2 sm

Nei analyze fan de fjouwer sets fan eksperimintele gegevens, kinne wy ​​lûke de folgjende konklúzjes:

 

As de skuorre kamera DG4Pros is:

(1) Mei / Sûnder grûnkontrôlepunt (GCP) en PPK-gegevens belutsen by de AT-triangulaasje, oft it in VTOL of in multi-rotor drone is, oft de GSD 2cm of 1.5cm is, it 3D-model boud troch skuorre kamera DG4Pros kin foldwaan oan de easken fan relative krektens flater Ds≤10cm (Eins ≤5cm).

(2) As de GSD de ienige fariabele is, is de relative krektens fan it 3D-model mei GSD = 1.5cm better dan dat GSD = 2cm.

Konklúzjes

De fariabelen fan eksperimint 2 binne:

1: Mei/Sûnder GCP's.

2: Different Carrier drone: in VTOL drone as in multi-rotor drone

Nei analyze fan de twa sets fan eksperimintele gegevens, kinne wy ​​lûke de folgjende konklúzjes:

 

As de skuorre kamera DG4Pros is:

(1) Mei / Sûnder grûnkontrôlepunt (GCP) of it no in VTOL of in multi-rotor drone is, kin it 3D-model boud troch skuorre kamera DG4Pros foldwaan oan de easken fan relative krektensflater Ds≤10cm (Eins ≤5cm).

(2) As de drager drone-typen de ienige fariabele is, is de relative krektens fan it 3D-model mei multi-rotor better dan dat mei VTOL, mar it ferskil is net heul grut.
