A 3D laser scanner is an optical measurement instrument which captures measurement points in the three-dimensional space without contact. By capturing a close-meshed point mesh, complex geometries can be represented in a so-called point cloud. For capturing more complex objects, several measurements from different perspectives are necessary. In order to merge the various scans correctly in analysis software at a later time, high-quality laser scanner accessories, such as reference marks (reference spheres, checkerboard targets), are required.
