3D Geometry - Measuring and Verifying
Various different objects, elements and systems must be checked to meet specified construction and operation tolerances (3D geometry). These tolerances are usually less than one millimeter. The 3D object geometry of various elements is comprised either from precisely defined distances between individual parts (parallelism, equal angle, etc.) and/or of an existing CAD model.
GLM provides and uses optical 3D measuring systems that meet these requirements. The non-contact laser measuring technology makes it possible to measure, verify, or monitor the 3D geometry of various objects (Deformation Analysis).
Specially developed software tools are used to compare the CAD data of the object directly and locally with the true object geometry. You also can compare and adjust the parallelism of individual elements (rollers, rails, steel beams, etc. ) in all three dimensions ( Y northing, X easting and Z height). The achievable measuring accuracy depends on the size and material of the object, and the atmosphere of the environment:
- The various 3D measuring systems are designed for objects with a size between 1 and 200 m.
- The accuracy to be achieved and reproducible is usually at1/10 mm.
GLM has been focusing on the measuring, verifying and documenting of the 3D geometry of individual objects since 1991. The left section lists a few areas of application where the 3D measuring systems from GLM have successfully gained a foothold.
More information about the implementation of specific geometric tasks is available in the following list:
