Drone 3D modelling

3D modelling and photogrammetry
by drone

Dronexperts produces faithful three-dimensional reconstructions of your buildings, industrial sites and land from aerial imagery. You receive a measurable digital model, usable for design work as well as construction monitoring, and ready to integrate into your existing software.

Why use a drone

A digital twin rather than a set of photographs

Drone photogrammetry captures a structure from hundreds of angles, then recalculates its actual geometry from those images. Where a conventional inspection produces isolated shots, you get a continuous model on which any distance, area or volume can be measured afterwards, without returning to site.

A drone covers in a few hours what ground-based surveying takes days to complete, with no scaffolding or aerial platform and without interrupting operations. Our pilots work on structures that remain in service, and we deliver measurable data rather than pictures alone.

Deliverables that fit your existing software

Deliverables

What you receive

Deliverables are defined with you at the scoping stage, based on the accuracy required and the software your teams actually use.

Point cloud and 3D mesh

The dense survey of the structure and its meshed version, the basis for any later measurement and a working reference for your design teams.

Georeferenced orthophotography

An aerial view corrected to scale and set in coordinates, on which distances and areas can be read directly.

Digital terrain model

The elevation profile of your site, useful for earthworks, drainage and layout studies.

CAD / GIS compatible deliverables

Formats that work directly in your design chains and geographic information systems, with no manual rework.

Use cases

When clients call on us

Design offices needing a 3D record of existing conditions before design work
Project owners tracking construction progress over time
Industrial operators documenting an existing site and its installations
Local authorities mapping a site or public structure

Our method

How a mission unfolds

Four steps, from the first conversation to the delivery of your data.

01
Scoping
We define together the perimeter, the accuracy required and the format of the deliverables.
02
Flight preparation
Feasibility study, analysis of site constraints and regulatory procedures.
03
On-site acquisition
Our remote pilots operate on site, without interrupting your activity.
04
Processing and delivery
Data processing, quality control and delivery of annotated results.

Nationwide coverage

We operate everywhere in France

Dronexperts operates across the whole of France. Our professional drone pilots travel to wherever your site is, anywhere in the country, and across Europe for the specific missions our industrial clients require.

Our 5 registered training centres — Paris West (Beynes, 78), Strasbourg (Schiltigheim, 67), Toulouse (Labarthe-sur-Lèze, 31), Marseille/Toulon (Le Castellet, 83) and Bordeaux (Mérignac, 33) — act as anchor points so we can reach every region quickly. They are starting bases, not a limit: we operate throughout France, with the same procedures, the same insurance cover and the same standards from one end of the country to the other.

Paris West — Beynes (78)

Our anchor point in Île-de-France: Paris, the inner and outer suburbs and the wider Paris basin.

Strasbourg — Schiltigheim (67)

Our Grand Est base: Strasbourg, Colmar, Mulhouse, Metz, Nancy, Reims and the German and Swiss border areas.

Toulouse — Labarthe-sur-Lèze (31)

Our Occitanie base: Toulouse, Montpellier, Albi, Tarbes, Perpignan and the whole South-West.

Marseille / Toulon — Le Castellet (83)

Our Provence-Alpes-Côte d'Azur base: Marseille, Toulon, Aix-en-Provence, Nice and the Mediterranean coast.

Bordeaux — Mérignac (33)

Head office and historical base of Dronexperts, in Nouvelle-Aquitaine: Bordeaux, La Rochelle, Limoges, Pau, Bayonne.

Is your site far from all five centres? That is not a problem: our bases are starting points, not a service perimeter. We organise travel for the team and the equipment anywhere in France, and across Europe for specific missions, on quotation.
