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

  • 3D Coordinates3D测量软件PONTOS - dp - dp: 生活的脚步,进步的点滴...
  • 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 Viewer

The free PONTOS and TRITOP Deformation Viewer allows for easily interchanging 3D measuring results and reports. For more details please read: PONTOS Viewer.

Features

Measurement

  • Measurement of high-speed or slow motion deformation, movements, deviations and displacements of single points (crash-tests, wind-tunnel, ...)
  • Measurement of velocities and accelerations of single points (directional, angular, ...)
  • PONTOS Real-Time Sensor, live tracking of ellipses in 3D without image saving, 3D coordinates of several points are computed in real-time on snapped images

Data Acquisition

  • Comfortable interface for different camera models
  • Flexible triggering of image acquisition (manual, time sequence, TTL signal or load signal from the experiment, ...)
  • Import of images from external cameras (TIFF, JPEG, PNG)
  • Integrated data logger and trigger box
  • PONTOS Real Time Sensor, Live tracking of several facets and ellipses in 3D without image saving, 3D coordinates of several points are computed in real time on snapped images

Computation

  • Stereo-image based evaluation technique
  • Automatic calculation of the 3D marker positions, their movement and the deformation of the object
  • Evaluation of relative motion between points
  • 3D graphical display of the resulting data
  • Components: Rigid body elements for automated point identification

Transformation and Registration

  • Transformation of multiple load stages into a common coordinate system (Elimination of the rigid body movement)
  • Transformation of 3D data into object defined coordinate system (3-2-1)
  • Registration of the captured data into predefined coordinate systems or into predefined geometrical elements (primitives)
  • Pre-registration and best-fit registration to reference or CAD data

STL and CAD Data

  • Import: STL data and CAD data, (CATIA V4/V5, Pro/Engineer, IGES, STEP, VDA, ...)
  • Calculation of the deviation from measured data to reference data (points, distances)

Primitives

  • Primitives (spheres, cylinders, cones, planes, lines, ...) can be generated from mesh data (certified by PTB and NIST)
  • Intersection and projection of primitives
  • Analysis of marker movement relative to primitives

Analysis

  • Displacement fields
  • Point positions, Distances, Angles
  • 6DoF / relative 6DoF
  • Velocities (directional, angular)
  • Accelerations (directional, angular)
  • Deviations and displacements relative to CAD data instead reference stages

Documentation & Reporting

  • Result data overlay on captured images
  • Result visualization of displacement images, graphical diagrams, analogue signals, ... in predefined or customized reports
  • Export functions for measuring arrays and selected data points
  • Export of result/inspection data as neutral file formats (HTML, Excel, ASCII, ...)
  • Optimized visualisation: linking of components (rigid body elements) to meshes or adapters, mesh moves with component
  • Automated update of reports
  • Interfaces to ARAMIS, TRITOP, ATOS
  • Generation of result-movies and image series
  • Free PONTOS Viewer to share results, reports and data analysis

Automation & Scripting

  • Macro and scripting functionality for repetitive steps
  • Automatic Quality Control including image analysis, registration, calculation of the deviations, data evaluation and report generation

GOM Adapter

  • Measurement of primitives and edges
  • User defined adapters for dynamic and automated primitive creation
  • Dynamic visualisation of primitives and edges

Help

  • Automated parameter suggestions for all important functions
  • Online Help

Software Administration

  • All software features completely controllable with separate administration licence
  • Adapt the software to company-specific workflows
  • Disable specific system menus and functions
  • Integrate user-defined scripts into menus
  • Lock system templates so that only company-specific templates are available
  • Block creation or editing of templates, scripts or automation protocols
