Laser scanning provides complete measurement data quickly

Vitomittaus Oy carries out laser scanning of all sites throughout Finland and, if necessary, also abroad. We perform scanning with a static laser scanner, a mobile scanner from a vehicle, and an aerial laser scanner using a robust drone or a manned helicopter.

Laser scanning

Laser scanning produces an accurate three-dimensional model of a built or unbuilt environment. The laser scanner sends laser pulses to the target, which are reflected back. The device's receiver measures the time between sending and receiving the laser pulse, and calculates the distance to the target based on this. Based on countless measurement points, a dense point cloud is formed, describing the shapes and properties of the environment. Modern pulsed laser beams penetrate vegetation excellently, and a single laser pulse can generate several different echoes in different layers of vegetation and finally to the ground. This enables accurate mapping of the ground surface even through very covered vegetation.

 

The applications of point clouds produced by laser scanning are almost limitless. They can be utilized in construction monitoring and documentation, as initial data for design, mapping terrain topography, forest inventory, and even in scientific research.

Laser scanning equipment

We use two static laser scanners, Leica BLK360 and Riegl VZ400. Leica's compact scanner is well suited for tight indoor spaces and shorter distances, while Riegl's more robust scanner is a better solution for large sites and open terrain. We perform mobile scanning with Riegl VMQ-1 mobile laser scanner from a moving vehicle, and if necessary also from a boat. We operate aerial laser scanning with Phoenix Lidar Ranger Ultra system, which has Riegl VUX-120 laser scanner as sensor. We use Finnish Avartek Boxer Hybrid drone for small and medium-sized sites. We can carry out the largest scanning projects or those located in difficult-to-access areas with a manned helicopter, in cooperation with Finnish long-term helicopter operator GridJet.

For many uses

For example, you will receive from us:


  • terrain models from mobile and UAV scans
  • Laser scanning of large areas or electrical networks using a manned helicopter
  • mobile scanning of road environments and highway tunnels by car
  • UAV or helicopter scanning of terrain and difficult-to-access targets
  • laser scanning of forests for inventory, planning and research purposes
  • scanning of building interiors and facades
  • scanning, site drawings and sections of old bridges for design
  • precision measurements of new bridges by scanning
  • accurate calculations of rock and dumping areas
  • scans of old conveyors for design
  • straightness measurements of elevator shafts
  • IFC models of buildings and infrastructure projects

 

These were just a few examples of possible applications. If you have a challenging measurement target, contact us and ask for a quote!
