Computer-aided techniques like CAD, CAM and FEM require an efficient coordinate measuring technique in order to achieve exact correspondence between numerical model and real component.

Using the digitizing system ATOS (Advanced TOpometric Sensor), an object can be measured in a short time and with high local resolution. Each single measurement generates up to 1.3 million data points. The individual measurements are merged into a project and the measured data can be exported as point clouds, sections or STL-data. Additional hardware, such as mechanical measuring machines, translation units or robots, is not required. See also ATOS System variants.

Applications

Non-contact and material independent 3d-digitization of arbitrary objects, such as workpieces, models, moulds, sculptures, human body parts, component damages etc. for:

• generating STL or CAD data

• transferring model modifications to CAD

• creating control data for the manufacturing on NC-milling-machines and rapid prototyping systems

• nominal/actual comparison between object and model (CAD model, point clouds or STL data)

• quality control, e. g. measuring deformations, fabrication defects, spring-backs

Measuring Procedure

The ATOS sensor head mounted on a tripod can be easily positioned around the object. During the measurement, fringes are projected onto the object surface and recorded by two CCD cameras. From these images the software computes the precise 3d-coordinates of up to 1.3 million object points. For a complete measurement of complex objects the individual views are merged into a single data set. The system automatically determines the current sensor position and transforms the individual measurements into a common object coordinate system. The operator is able to control the progress on-screen at any time. The calibration of the system, any object or sensor movement and the impact of environmental light is controlled during each measurement, thus ensuring precise and fast measuring even under rough industrial conditions.

Features:

• Simple operation:

  The user can concentrate on the digitizing progress as all the transformations are performed automatically by the system.

• Flexibility:

  The same sensor (ATOS XL) is capable of measuring small and large objects (10mm up to 10m).

• High detail resolution:

  Due to the high point density, details of the component can be depicted precisely. The accuracy of the measured data is comparable to that of single frame coordinate measuring machines.

• Mobility

  The system can be transported in two flight cases (part of the standard equipment) by car or plane
