3D terrestrical laser scanning 

By means of terrestrial laser scanning, COWI registers the 3D geometry of an object.
3D terrestrial laser scanning makes it possible to register the 3D geometry of an object with great accuracy and efficiency.

This technique is especially suitable for surveying in relation to documentation of constructions, industrial facilities, processing plants, production platforms, plant constructions, bridges, buildings, etc.

Point cloud and modelling

The result of a terrestrial laser scanning is a 3D geo-orientated point cloud with a resolution down to less than 1x1 mm.

The point cloud can be used, for instance, to make a clash check with a 3D model of a new design or COWI can model the point cloud to 3D objects, surfaces and other geometric figures before these are processed in CAD, for example Microstation or AutoCAD.

The 3D model can be used as documentation, basis for operation and maintenance, new design basis or project planning.

Accuracy of 2-5 mm

During a scanning session, more than 1,000 points are surveyed per second. Modelled objects will typically have an accuracy of 2-5 mm, dependent on the structure of the object and the accuracy of the single scanned points.
