V8 - New Version of the 3D Digitizing and Inspection Software

GOM's V8 software for ATOS, TRITOP, PONTOS Live, GOM Inspect and GOM Inspect Professional has now been launched in the market. The new application solutions provide enhanced optimization of measurement processes and increase inspection efficiency.

The V8 software also provides measurement and inspection functions for 3D analysis in point-based deformation analysis. In addition, V8 offers a live add-on module and a stand-alone PONTOS Live software package for the following applications: real-time object tracking, online part positioning, touch-probe measurement and online deformation and movement analysis of 3D coordinates. GOM has also optimized some automation features in order to achieve greater time-savings, process reliability and reproducibility.

New functions in the GOM V8 software include:

Local Coordinate Systems

The local coordinate system in the V8 software makes it possible to perform local or drawing-based evaluations. The new functions simplify, for example, dimensioning within a coordinate system. Standardized GD&T position analysis can be combined easily with local coordinate analysis in the same reference system. In addition, local coordinate systems can be used to implement complex alignment strategies such as “balanced beam” and “equalized nested”, for example on turbine blades. Local coordinate systems also form the basis for 6DoF analysis.

Deformation analysis with GOM Inspect Professional V8

Evaluation features of the V8 software 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. Additionally, the 6DoF analysis can be used to ascertain translatory and rotatory movements in a reciprocal or absolute context for all dimensions. Finally, operators can generate attractive video sequences from the evaluations for use in reporting.

Golden Mesh

For many applications, including trend inspection, reverse engineering and tool manufacturing, the calculation of a Golden Mesh is required. The V8 software from GOM allows the determination of the Golden Mesh by either finding the best mesh or calculating an average mesh. The best mesh is an original mesh, which is determined to have the least deviation from an average data set. The average mesh is a new mesh, which is calculated based on a set of multiple meshes. When determined, the Golden Mesh can be exported as STL for reverse engineering to CAD or used as a reference for future part inspection.


A timeline integrated in the graphical interface supports the management of multi-stage projects, for example in statistical process control (SPC) and deformation analysis. Deformation stages can be imported into V8, and point movements and deformations are visualized over a timeline on the basis of vector fields. In addition, multiple meshes can be loaded to enable stage-based evaluation. The software user can switch back and forth between stages within a trend project or display relevant/defined stage areas exclusively in order to determine how individual components deviate from CAD or from each other.

Live Module for ATOS

The live module allows ATOS 3D scanners to be employed for live measuring of movements and deviations, in addition to full-field scanning. This tracking is based on the stereo camera principle in connection with the GOM reference point system. Single points as well as complete components geometries can be traced in space. The alignment or positional deviation of a component from the nominal position can be measured and visualized. The core function is the transfer of the virtual alignment of components into reality.

PONTOS Live – Stand-alone software package

PONTOS Live is a stand-alone application and metrology system, allowing online measurement, positioning and motion analysis of 3D coordinates. PONTOS Live precisely measures and evaluates data online from an unlimited number of 3D measuring points. The fast and non-contact measuring system can be used for all aspects of online component testing such as performance, durability and reliability testing, wind tunnel testing, vibration analysis and NVH, and it can be integrated easily into existing test environments.

Virtual Measuring Room V8

The new VMR workspace, which includes an auto-teaching function, reduces programming time and the need for specific robot programming skills. The V8 software automatically generates the correct sensor position for each feature being measured. The ‘Virtual Camera Images’ function first visualizes the image recorded by the sensor cameras in each calculated position before operators are able make minor corrections in positioning where necessary. During path optimization for the ATOS ScanBox, the software automatically calculates intermediary positions along its travel line in order to preclude collisions. At the same time, the duration of travel and robot movements are optimized by making adjustments to the sequence of positions.
