3D Model for integration into CAD using photogrammetry

The below case study shows some of the parameters extracted from the survey. With a ground resolution of 2.4cm per pixel. Covering an area of 0.346 Km2. This model was produced with no disruption to the site using a pre programmed flight grid. Procesing was done on our inhouse computer suite and delivered with in 24 hours.

How Photogrammetry works

Drones have been known for their lower cost ability to take photographs on sites, for real estate, agriculture, building, and inspections and more. Technology now enables the use of drones combined with specialised software to create 3D models and mapping to a high level of accuracy.

Advantages of 3D Models with drones

The advantages of using real 3D information in which a realistic view is created of a certain region on earth are numerous going further than the simple notion of cost effectiveness.  Next to the realistic 2D or 3D mapping experience in visualizations, the use in algorithms, such as signal propagation algorithms, or in perception studies create a large advantage for local authorities, planning, architecture, real estate development and integration into existing work flows. The data collected for the modells is non disruptive and will negate the need for expensive down tome on site.

How Accurate is a drone Survey?

One of the most important parameters of your survey is the spatial resolution, which in photogrammetry terms is described as GSD (Ground Sampling Distance). In literature, it is defined as the distance between two consecutive pixel centers measured on the groour practice, it is simply the size of the pixel in the field.  1 cm (3 inches) pixel size using our DJI Mavic Pro, at an altitude of 25 m.
