UAV Photogrammetry

Better data saving time and costs

Photogrammetry using unmanned aerial vehicles

We use unmanned aerial vehicles (drones) to save time and lower costs when plotting and planning sites. We are able to produce survey-grade maps and accurate 3D models.

That’s why drones have become an integral part of our toolkit. Paired with powerful processing capabilities, we are able to produce survey-grade maps and accurate 3D models, providing clients with better data, saving time and costs. 

Project managers and virtual design coordinators can save valuable time and eliminate risk through the use of drone maps and 3D models. Whether keeping construction projects on track with sharable maps, comparing BIM models, inspecting job sites for safety, or measuring stockpiles and earthmoving volumes, data gathered with drones improves communication and make construction a more efficient and safer industry to work in.

Real world information into the digital world:

- Plan

Safety is paramount while flying any aircraft. There is a lot on the line with incorporating drones into the workplace. Being aware and accepting that risk is part of managing any drone operation. We take the necessary steps to ensure we are minimizing that risk and doing everything to support a safe environment. Our flight team needs to locate any potential hazards that may occur in advance. Our team will have to be aware of any airspace regulations, structures, persons, or equipment that is nearby and plan accordingly. Our experts make sure we always plan our operations according to environment and the weather. All of this and much more make it crucial to have a solid plan before starting any mission. Preplanning for desired accuracy and ground resolution, necessary ground control and various other flight parameters is essential for high quality results.

- Ground control

To collect highly accurate data, dense network of ground control targets needs to be placed and measured before the flight operations can begin. Recent advancements in GPS technology have reduced this need somewhat, but for projects where        cm-level accuracy is crucial this is still big part of the process.

- Fly

Scanning the project site using an unmanned aerial vehicle equipped with high resolution camera to capture real world information of buildings, infrastructure and industrial facilities into the digital world. Images captured are photogrammetrically evaluated in order to create three-dimensional models, the quality of the lenses used is highly important for this type of task. We use only the best Zeiss Batis lenses. This allowes us to gather very high quality images, thanks to the superior geometric and radiometric quality of these lenses. All members of our flight crew are trained professionals who are able to both focus on delivering highest quality data and maintaining safety of the operations. 

- Process

Once the existing conditions are captured into high resolution photographs, 2D information is then brought into processing software to generate 3D point clouds. 3D point clouds are then ground controlled and further processed to extract ground, buildings, vegeteations, etc. depending on the project needs.

- Quality control measure

All our measurements of terrains are quality control checked in accordance with Swedish standard SIS-TS 21144:2016.

- Deliver

Extracting 2D and 3D data from point clouds is the most critical step in the photogrammetry process. Profiles, elevations and 3D models (terain models etc.) can be efficiently generated by intuitive extraction workflows. Analysis tools allow comparison of as-built conditions with digital CAD models. All this leads to detailed suggestions for planning and the development of infrastructure projects.

*Document existing site conditions

Solutions for the efficient and precise capturing and processing of emerging and existing site conditions for road and rail construction, residential construction, energy and industrial plants.

** Our extensive knowledge in unamenned aerial vehicles can be leveraged for various building, infrastructure and insurance inspection scenarios. We can fly drones to inspect sites and infrastructure more efficiently, and in a safer manner. Using drones, building inspectors can identify issues on roofs, building exteriors, and elevated towers without the need to spend hours walking or climbing a site. This eliminates the need to send workers into unsafe conditions unless it’s absolutely necessary. For insurance inspectors, drones streamline the claims process, making it easier to assess property and get customers back on their feet quickly.
