3D scanning: Industrial and Engineering
Breuckmann 3D white light scanners produce high-resolution 3D scans with millions of data points. Even the smallest objects can be accurately recorded in three dimensions using this close-range scanner. Scans may be used for quality inspection or may be converted into realistic 3D models and can provide the basis for reproductions and/or archival records.

Digitization of a brush for washing dishes
Telex, a telecommunications customer, had fragile metal parts which required high accuracy cross sectional information. Because of the tendency of the material to flex under the lightest pressure, equipment that touches the part, such as articulated measurement arms or coordinate measuring machines could not provide the solution. Accurex Measurement used the Breuckmann OptoTOP HE structured light scanner to collect dimensional information about the part.
The scan data was collected in about a second. In practical terms this means that there is very little possibility of an object moving during the data acquisition stage. This was particularly useful capability in this case because the fragile nature of the part meant that it would most likely be deformed if any effort was made to clamp it down during the measurements.
Because much of the part consists of shiny materials, many scanners would require the use of a non-reflective powder. However, the OptoTOP HE was able to measure the reflective surfaces without any coating.
Measurements have been carried out at a number of test tracks in various countries. As the topographic data of the test track road surfaces is used for computer simulations of chassis movements it needs to be very accurate with depth determined to a local accuracy of 1mm or better. A further requirement is that all the scans be tied into on very large dataset.
A vehicle is equipped with two scanners. They are mounted side-by-side on a fixture which is firmly attached to the van's roof rack. The OptoTOP-HE consists of a light projector and digital camera rigidly attached to either end of a fiber composite bar. The scanners are positioned so as to capture overlapping images to allow the adjacent field of view to be stitched together. The controlling software, OptoCAT which has been customized for this particular application by means of its built-in macro programming language capability. OptoCAT also allows for the alignment of overlapping point clouds so that the scanning system can be used to measure large parts.
OptoTOP HE 3D scanning system by Breuckmann was used to digitize a designer brush for washing dishes. The requirements for the scan were that there could be no pre-treatment of the object surface, particularly spraying with powder; no contact measurement; a low measuring time; and the surface data of a closed volume model would be delivered in STL format.
Because the alignment of single view by means of the object geometry is realized interactively, no special fixing of the object is necessary. The scans of the brush were taken by putting the brush in different positions to develop a full 3D model.
