Mobile Optical 3D Measuring System for Online Photogrammetry

ONTOS Live is GOM’s tracking system for positioning components, as for a precise alignment on CNC machines or for the adjustment of fixtures. Combined with the GOM Touch Probe, PONTOS Live allows the inspection of areas that are optically difficult to access.

Based on the triangulation principle, PONTOS Live analyzes components of different sizes – from a few millimeters up to several meters – point by point and regardless of the material.

Modern product development demands a better understanding of the dynamic component behavior. This requires an efficient component development of just a few iteration cycles. For the measuring technology to be used, this means that in addition to high absolute accuracies, numerous measuring points and an efficient practical handling are required.

In contrast to conventional displacement measuring systems, the PONTOS system reduces the measuring procedure to a fraction of the time. In addition, the understanding of the measuring results is visually supported by an animated representation.

PONTOS replaces conventional displacement measuring systems and accelerometers. Independent of the structures to be measured, displacements and deformations are captured rapidly in a non-contact manner.

 

  • Door/hood slam
  • Dynamic behavior of components
  • Component position in windtunnel
  • Deformation measurement of aerodynamically loaded structures
  • NVH
  • Drop tower tests
  • Verification of simulations

PONTOS FEATURES

  • Simple specimen preparation
  • Ultra-light measurement targets
  • Frame rates independent of the number of the captured markers
  • Customized triggering of the image acquisition
  • Recording of analog signals
  • Insensitivity to ambient conditions, such as vibrations and light changes
  • Easy adjustment to different measuring areas and tasks

MEASURING TASKS

The easy handling of the robust measuring system allows its use directly on-site with the component to be measured in its natural installation position and environment.Complex measuring tasks in the automotive industry as well as in the aerospace industry can be solved easily and fast.

  • Complex motion analysis
  • Component deformation
  • Mode shapes
  • Relative motion
  • Gap size changes
  • Flush

RESULTS

The dynamic measuring system PONTOS provides for any number of measuring points information about:

  • 3D Coordinates
  • 3D Displacements
  • Deformation
  • Speed
  • Acceleration

These results are presented in versatile manners and are available to export as ASCII datasets. Due to a visualization of the recorded camera images combined with diagrams, the component behavior can be analyzed easily and in an intuitive manner.

PONTOS Live - Mobile Optical 3D Measuring System for Online Photogrammetry

Live functionality

The live functionality allows online measurements and online positioning. It is supported when measuring with GOM Touch Probes and GOM Adapters, so that components can be specifically aligned and positioned to the CAD in an online measurement.

Stereo camera

The stereo camera system provides precise 3D coordinates of reference point markers. The preset and certified lenses are integrated into an industrial housing, leading to high stability with fewer requirements for sensor calibration. Users can easily change the measuring volume and thus measure small to large objects.

GOM Touch Probe

The GOM Touch Probe is a tactile add-on for measuring systems, which is optically tracked by the system. It is used for tactile measurements and allows measuring coordinates even in areas that are difficult to access.

GOM Adapter

The GOM Adapters offer expanded options for the live measurement such as component positioning or the measurement of geometrical elements and edges.

COMPLETE WORKFLOW IN ONE SOFTWARE APPLICATION

The entire measuring, evaluation and documentation process is carried out within the integrated PONTOS Software. The full potential of the available hardware is used to capture and evaluate the measuring area efficiently and with high accuracy.
