Landmeten met drones is méér dan het maken van een paar foto's van bovenaf.
Surveyors and GIS professionals place the highest demands on their quality and tools.
No wonder many surveyors use our drones for mapping and 3D modelling.
Survey drones consistently achieve results that meet accuracy standards. In comparison with traditional surveying techniques, drones significantly reduce the time, cost and effort required.
Landmeten met drones is ingewikkelder dan enkel het maken van een paar foto's met de drone.
Several steps are required such as preparing ground control points, planning missions and
het verwerken van de beelden die u vastlegt met "landmeetkundige" software.
What is oblique photography?
Oblique photography is a technique that can be used in 3D modelling. Here images are captured by five lenses. These multiple lenses are mounted together in an array with fixed axis angles.
These images reveal details sometimes overlooked when photographing only vertically, such as features hidden by vegetation or tall structures.
De ATL 102S V3 oblique camera maakt gebruik van een mechanische opstelling met vijf camera's in vaste posities in een kruisconfiguratie. Eén camera in het midden is omgeven door vier andere camera's, voor, achter, links en rechts, met een gelijke afstand van 90 graden. Dit systeem plaatst de centrale camera onder
een schuine hoek waarbij de "nadir"-hoek (het punt direct onder de camera op grondniveau) zich op een bekend, vast punt in het kader bevindt.
3D recording techniques
Surveyors are often tasked with creating high-resolution orthomosaics. These can be constructed using photogrammetric technieken waaruit 3D-modellen gemaakt worden door schuine camera's en 3D-opnametechnieken.
With the combination H850-RTK+ATL 102S V3, surveyors have the ultimate surveying solution at their fingertips. In terms of accuracy and efficiency, this is of enormous added value for professionals. Thanks to the ATL 102S V3 oblique camera, surveyors can now create 3D models of their objects more efficiently than ever before.
The benefits of oblique photography
Images captured with an oblique camera (ATL 102S V3) reveal details that are hidden by foliage or tall buildings when viewed vertically.
Oblique photography makes it easier to accurately determine the height of objects compared to vertical aerial photography. Unlike an orthographic setup, where the central camera looks straight down, the oblique system records much more height data.
This also rules out lens distortion in all directions around the focal point, which the orthographic method still sometimes has problems with.
With multiple shots at controlled intervals, the position and relative height information of each dataset can be compared, contrasted and then merged.
to obtain relative elevation information between features in the target area, creating a map with both position and elevation data, which can be displayed as a 3D map of the surveyed area.
