3D Laser Scanning Laser scanning can reduce time spent on site to a matter of minutes, using this remote measurement technique also enables work to be undertaken from a safe vantage point away from open lines.

High definition laser scanning enables the quick acquisition of millions of dimensionally accurate 3D data points. The resulting 'point cloud' can be manipulated to produce a variety of end products, including 2D or 3D CAD drawings and object ased 3D modelling.
From a place of safety, a static scanner at the side of the track can make a complete 360 field-of-view scan of all details within a range of 50m to an accuracy of better than 5mm. In excess of 40 million points are collected in little more than six minutes.

The laser scanner can also be used in a dynamic mode by attaching it to a track mounted trolley, using it in this way enables continuous profiling data to be captured; this is particularly useful for measuring clearances beyond a structures profile, such as in a tunnel.
