OUR EXPERTISE :

By drone, with rolling or walking solution, underwater, we realize 3D modelization faithful to the reality or in false colors (levels of reflectance, IR, NDVI, etc), georeferenced and or metered with a level of precision previously defined ( choice of sensor or techno).

 

 

Pilgrim Technology adapts its robotic solutions to the needs of its customers by integrating different sensor technologies.

The data collected by the onboard sensors are then processed and used internally by our Data Processing department. The results are sent to you for exploitation.

  • Reliability and security of robotic solutions
  • A professional protocol for collecting data
  • Creating a customized and unique design
  • Anticipation of development with innovative technologies

 

Photogrammetry :   

This technology allows, through an algorithm Structure from Motion, to assemble photographs and render a 3D model identical to reality.
From our different sensors, we can realize RGB, thermal, multispectral and infrared renditions.
Photogrammetry allows you to work on all scales, from museum objects to large natural areas, to industrial and heritage buildings, area or district.

We work from data captured by our care, or your own data, then undergo the following methodology :

  • Control of photographs
  • Image matching process
  • Densification of the point cloud
  • Implantation of the georeferencing points or the measurement of the model
  • Classification of points clouds as needed
  • Model meshing
  • Texturing
  • Quality Control
  • Qualimetric report

Lasergrammetry :  

Particularly interesting when it comes to digitizing 3D interiors, lasergrammetry allows the realization of a 3D model so the geometry will be similar to reality and defined to the precision that meets your needs.
From different lasers, handheld, tripod, or embedded on a drone, it is possible to scan in three dimensions all types of objects, sites, buildings, etc.

We work from data captured by our care or your own data, then apply the following methodology

  • Point Cloud Control
  • Implantation of georeferencing points or footage
  • Point Cloud Matching Process
  • Classification of points clouds as needed
  • Quality Control
  • Quality ratio

LIDAR :  

Embedded on a drone, the LIDAR system exploits LIDAR: the waves of the infrared, the visible or the ultraviolet. By measuring the elapsed time between the emission of a laser pulse and the return of this pulse, the LIDAR obtains the distance information between itself and the surface overflown.

LIDAR can also model all objects present between itself and the ground. Thus this technology allows us to obtain a point cloud of a forest cover but also of the ground under this cover. Finally, by classification of the point cloud, it is possible to select only the level of cloud that interests us.

With built-in RTK beacon, the LIDAR allows automated positioning of point clouds with a precision <2cm :

  • Acquisition flight
  • Point Cloud Matching Process
  • Classification of point clouds as needed
  • Quality Control
  • Quality ratio

 

 

All laser or photographic sensors can be used to perform data processing, however, it is obvious that a poor quality sensor will produce a poor quality result.

It is possible to combine several of these technologies to respond to complex situations or environments (industry, oil, gas ...).
