The right equipment
for the best data
LiDAR is a 3D scanning technology that relies on laser-emitting sensors to measure distance, allowing a point cloud model of the desired environment.
Its advantages are centimetric accuracy, speed and As-Built measurement acquisition - often where it would be difficult or dangerous to access.
It can cover large horizontal surfaces quickly; for example, up to 10,000 m² in only 20 minutes by drone, 400m² when surveying buildings and 750 m3 for telecom towers. It can also cover vertical elements easily – for instance 800m of cable for high voltage electrical towers.
Mines or technical tunnels also benefit from LiDAR since it can scan up to 1km in a mere 20 minutes using a robot (UGV).
Finally, bridges of up to 1km can be scanned in only twenty minutes using UGVs.
LiDAR offers truly remarkable capabilities that provide detailed information while being cost effective and reliable.
Multispectral imaging is a powerful tool that can be utilized to analyze surface features on land.
It allows for the determination of diverse built-up materials and the structured zoning of different topologies, such as forested areas or water bodies.
An example of this is the Normalized Difference Vegetation Index (NDVI). This type of imaging can be used to measure soil water availability, foliar nutrient content when water is not limiting, and potential yields for crops.
Multispectral offers users a practical way to observe features that were previously difficult or expensive to monitor, thus revolutionizing our understanding of land surfaces.
High precision / long range laser
High-precision, long-range laser rangefinders are essential for accurately measuring elements on the horizon when sites and assets are obstructed.
These devices offer extremely precise distance readings of +/- 20 cm variations on a range of 1,200 meters, while also providing measurements with significant accuracy and repeatability.
With this kind of technology, long-distance measurements can be taken without having to risk putting personnel in harm’s way.
Additionally, they allow stakeholders to quickly and easily take highly accurate readings without having to invest in costly infrastructure or require expensive calibration processes.
Extra HD photo (Zoom) technology offers an incredible level of precision, allowing you to capture remote elements with unprecedented visibility.
With its 20MPixel camera and 23x optical zoom capability, it is possible to read a label from as far away as 60 meters, while centimetric writing can be read from a distance of up to 100 meters—meaning that each pixel has only 0.75cm of size at 60m.
Thanks to this amazing technology, it is effortless to analyze infrastructures with extraordinary details.
360 panoramic photos offer an uniquz way of capturing a moment and its surroundings in one complete image.
By taking multiple photos around a 360-degree field, all elements can be seen together in the same shot.
This type of photogenic technique is often used to document fields obstructing the horizon, such as antennas on telecom towers.
Since panoramic photos are never constrained to just one angle, they open up the possibility for documenting all the obstructions normally unseen by the everyday observer.
Infrared technology is an advanced method of measuring and controlling energy performance, thermal defects, and the radiant temperature of all kinds of assets.
It offers much more accurate measurements than traditional methods, allowing businesses to optimize energy use across production systems.
An example of its application would be verifying the operating temperature of antenna equipment.
This simple measurement can prevent deterioration due to high temperatures that cause failure in electronic components, leading to significant savings over time.
With infrared technology, businesses can get a better understanding of their assets’ function while actively avoiding disruptions in their production process.
GNSS stands for Global Navigation Satellite System and is a satellite-based technology that allows georeferencing of measurements with up to 1 cm precision.
It provides great advantages when creating maps: allowing faithful reprojection of scans directly onto existing maps using precise geo projections (WGS84) and therefore can be imported in GIS softwares and platforms (ArcGIS, QGIS, OpenMap, Géoportail...).
It also provide a complete transformation matrix that can be used to geo-aligned, correct and enhance any 3D scans or Photogrammetry results, providing real accuracy on top of the precision of each scans technology.
Furthermore, it can be used to extract the orientation (azimuth) of any scanned asset, even those as big and bulky as telecommunications towers with their complicated arrays of antennas.
By having extremely accurate orientation data on these types of large structures, engineers can anticipate potential disruptions in transmission caused by other nearby towers or buildings before they happen.
Photogrammetry is a powerful tool for reconstructing the environment accurately and to scale in 3D.
The process involves taking multi-angle photographs of the area/assets in controlled lighting and then combining these into a photorealistic 3D model.
In some cases, LiDAR scans and GNSS/RTK geo-coordinates acquisition are performed beforehand to ensure the accuracy of the reconstruction.
A recent example of this can be seen at the Minèresbunn, where a photorealistic 3D reproduction of a mining museum was created using Photogrammetry and other visualization techniques.
This demonstrates just how powerful Photogrammetry can be as a tool for accurate and compelling visualizations.
Point clouds can provide valuable data for the classification of different volumes in a building.
By analyzing point clouds, it can be possible to differentiate walls, floors, ceilings and structural elements from each other as well as detect gas/heat/electricity networks and recognize many other assets.
For example our models are trained to detect and classify antenna's bodies on telecom towers to inventory them and verify their alignements.
On top of this, based on photos and point clouds, it is also possible to classify building elements such as walls, floors, ceilings, supports and frames as well as wall equipment (switches) and ceiling equipment (lights). This can then be used to automatically prepare an inventory base (BIM) which is a useful tool for gaining an extensive knowledge of a building.
