6d marker for the measurement of 3D coordinates and displacements with a single camera

The LIMtrack6D system measures 3D coordinates and 3D movements of coded 6DOF markers with a single camera.

The coded marker provide 6 degrees of freedom (6 DOF) consisting of 3D coordinates (x, y, z) and 3D orientation (roll, pitch, yaw).
The marker have a unique binary coding with 32 different IDs for a clear identification.
The holographic pattern provides accurate measurements of the 6DOF marker orientation.

Your benefits for the testing are:

  • 3D data instead of only 2D data
  • Cost saving
  • Time saving
  • Accuracy gain
  • Reliability & Repeatability
  • Error prevention

LIMtrack-6D is a fully automatic 3D marker tracking and 3D motion analysis software that is easy to use.
LIMtrack-6D calculates displacements, speeds, accelerations or angles from the measured marker coordinates and generates meaningful visualizations as diagrams and videos.

The focus is on your application

Based on integrated scripting, LIMtrack-6D can also perform complex measurement tasks fully automatically, quickly and reproducibly.
Example rear impact test (Wiplash): With a single mouse click the image sequence is automatically evaluated, marker ID assigned, measured values according to the test standard calculate and the results reports generated. Diagrams are created with the time course of the relative speed between the dummy head and the slide as well as the seat inclination angle, maximum values ​​are automatically determined with the corresponding test time.
The analysis modules are based on powerful scripting and enable the definition of individual calculations and visualizations.
The application modules can be created by the user himself or by LIMESS support.

Real-time option (LIMtrack-6D-RT)

With the real-time system LIMtrack-6D-RT, marker tracking is carried out in real time with a measuring rate of up to 10 Hz. There is no recording and subsequent evaluation of the image sequence. The log file contains the measured coordinates and angles and serves as the basis for subsequent application-specific movement analysis.

The LIMtrack-6D software offers

  • Fast and fully automatic camera calibration
  • Automatic marker tracking
  • Automatic post-processing, calculations, visualization
  • Powerful analysis modules for application-specific measurements
  • Data export e.g. ASCII, ISO standard
  • The integrated scripting kernel enables individual calculations and visualizations
