Mobile scanning survey

The innovative mobile scanning system enables a three-dimensional survey of structures and portions of land along a road axis, a coastline, a rail route, a rocky ridge, etc., in which geographically referred geometry is necessary, for all study, design and status quo analysis requirements.

The systemadapts to differentsituationsofmobility, throughvariousinterchangeable supportequipment platforms,such ascar, boat, etc., usingdifferentpositioning andgeoreferencing systems.

The mobile laser scanning system includes:

  • thelaserscannersensorfor measuring thegeometry of the objectof surveythrough the acquisitionof the spatial coordinatesof all surfaces(road sections, artefacts, natural elements, appliances) on thepath of the vehicleorvesselon whichthe system is installed.
  • an inertial IMU/GPS sensor, for determiningthe position and orientationof the mobile platforminside theWGS84 coordinate system;
  • dedicated softwareforprocessinggeometriclaserscannerinformation anddataon the position and orientationof the platform;
  • a digital camerasynchronizedwiththe laser system/IMU/GPS, mountedon the same platform.

The result of the survey operations is a 3D model consisting of points in XYZ space and information related to the texture (RGB). This model, properly processed using specific algorithms, means that three-dimensional and two-dimensional graphics of artwork and/or of the portion of territory detected can be extrapolated.

The benefit of this method is that it can perform a high speed survey of all those areas which are difficult to access, such as roads, shorelines, railways and curtain walls of buildings, for which alternative survey techniques cannot be applied, either for reasons of logistics or survey execution time.

Among the various application fields, mobile scanning is particularly successful in surveying the coastline to investigate problems of erosion and instability of the coastal cliffs.
