Digital Image Correlation (DIC)

Non-contact measuring technique based on Digital Image Processing. DIC is capable of mapping 3D coordinates and evaluating displacement and strain maps on the surface of measured samples. DIC uses a stochastic pattern and/or point markers to track the surface of the materials with subpixel accuracy.

This technique can be used for a wide range of applications in materials research and component testing to analyze the static and dynamic behaviors of specimens. The full-field strain map generated by the DIC algorithm is commonly used to replace strain gauges and other traditional sensors for simulation (FEA) validation.

Photogrammetry

The GOM Suite software is used to analyze the high-resolution images captured by our various measurement systems, including ARAMIS, TRITOP, and ARGUS. Features such as reference points, contrast lines, and adapters are determined quickly and accurately and displayed in the software including the calculated 3D coordinates. Measure and inspect not only small components but also larger parts like fuselage, trains, ships, and wind power units. 

The basic software functions include capturing measurement points and processing them to model 3D point clouds as well as monitoring image quality. Tools such as CAD data import, the import of measurement plans, alignment, point deviations from CAD, calipers, angles and diameters, vector fields, GD&T analysis and reporting are available for the purpose of quality control and results analysis.

TRITOP camera
Evaluation features are available for the deformation analysis of points. They define and analyze motions and deformations on the basis of a component concept. To make this possible, inspection points are divided into coherent groups. Transformations or corrections to rigid body movements can then be calculated for these components.
 
 
 

The local coordinate system in the software makes it possible to perform local or drawing-based evaluations. Hence, the dimensioning within a coordinate system is possible, standardized GD&T position analysis can be combined easily with local coordinate analysis in the same reference system and complex alignment strategies can be implemented. The local coordinate systems also form the basis for 6DoF analysis.

 
Parametric inspection is a tried and proven software concept in which each individual element retains its path of creation. All evaluation steps can be traced and therefore easily modified and adjusted. A one-button solution updates all dependent elements automatically after changes have been made. Parametric inspection is also used on numerous data records for trend and deformation analysis. This makes it easy to analyze several components or stress phases within a single project. With the TRITOP measurement system and full parametric inspection, GOM has therefore standardized the function base for deformation analysis.
 

A timeline integrated in the graphical interface supports the management of multi-stage projects, for example in statistical process control (SPC) and deformation analysis.

The software user can switch back and forth between stages within a trend project or display relevant/defined stage areas exclusively.

The WLAN assistant handles image transmission and provides direct feedback on image quality. Users are given immediate feedback on whether an image is too bright, too dark, or out of focus.

Dual-coded points are detected automatically. An online search for multiple identified coded points can be easily implemented.

TRITOP Professional offers optimal orientation during measurements with its image mapping and 3D views. In addition, image mapping also allows fast and easy project navigation during analysis. Individual color-coded CAD deviations and vector displacements can be visualized easily within the color images. So that operators can work with a specific image during all work phases, an image from one stage can be displayed through several stages in TRITOP multiphase projects. Image mapping is therefore one supporting element in the presentation of results.

Computed Tomography (CT)

This technique is mostly known in the medical field to measure inside the body. It is gaining momentum in the manufacturing and testing markets as a non-destructive method appropriate for accurately measuring the inside of components. Based on X-Ray imaging, the CT software assembles images taken from different angles into a 3D model of the object measured. The resulting model is a 3D image where each voxel (pixels in 3D) contains information on the density of the material. A meshing algorithm is then used to separate the densities into regions and polygonize the surfaces into meshes. Metrology inspection tools are used to measure the dimensions of these surfaces, just like with a 3D scanner. The possibilities of inspections are then virtually infinite, from CAD comparison, GD&T, or trend analysis to FEA validation.

This technique can be used for a wide range of applications:

Thermography

ARAMIS can be synchronized with a thermal imaging camera to capture temperature information. The temperature data can be imported, aligned, and mapped directly to the inspection and can then be used with other measurement data and be displayed by itself for 3-dimensional viewing. Each thermal pixel is projected onto the corresponding point of the surface mesh. The mapped values can then be inspected the same as any other ARAMIS inspection, finding maximums, minimums, averages, placing discrete points, and section lines across the data.
