LIMtrack6D - System for 3D Motion Tracking and 3D Motion Analysis with a single camera

Innovative functional principle

LIMtrack6D is a new measuring system for 3D motion analysis. Thanks to the special 6D markers, only one camera is required to measure 3D coordinates and 3D movements.

With a 6D marker, all 6 degrees of freedom can be measured directly. The 6 degrees of freedom consist of 3D coordinates (x, y, z) and 3D angles (roll, pitch, yaw).
Binary coding with 32 different IDs ensures that each marker is uniquely identified.
Thanks to the holographic patterns, the 3D markers provide orientation (angles) with high accuracy.

The markers are calibrated and therefore provide precise 3D coordinates for movement analysis with just one camera.

6D marker for the 3D motion analysis with a single camera

Measurement of 6 degrees of freedom (3 coordinates + 3 orientations) from one marker

Automatic and robust marker tracking

Automatic camera calibration

Integrated application modules and scripting for automatic post-processing

approval by Euro NCAP

Your advantages in the test environment are:

3D coordinates provide more information than 2D tracking
Easier to use and more cost-effective than a stereo camera system
Little time required for system setup and calibration
Accuracy gain compared to 2D measurements
Reliability, repeatability and error prevention through automatic tracking and post-processing

Image analysis with the LIMtrack6D Software

LIMtrack6D is a fully automatic 3D marker tracking and 3D motion analysis software and is very easy to use.
With a single mouse click LIMtrack6D measures coordinates, displacements, speeds, accelerations, angles and many more and generates meaningful visualizations as diagrams and videos.

The focus is on your application

With the integrated scripting, LIMtrack6D can also perform complex measurement tasks fully automatically, quickly and reproducibly.
This video shows how a rear impact test (Wiplash) is analysed automatically within 90 seconds: With a single mouse click the image sequence is automatically evaluated, marker IDs assigned, measured values according to the test standard (e.g. Euro NCAP) calculated and the results reports generated. Diagrams are created with the time course of the relative speed between the dummy head and the sled as well as the seat inclination angle, maximum values are automatically determined with the corresponding test time.
The analysis modules are based on powerful Scilab scripting kernel 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 (LIMtrack6D-RT)

With the real-time system LIMtrack6D-RT, marker tracking is carried out in real time.
There is no recording and subsequent evaluation of the image sequence necessary.
The log file contains the measured coordinates and angles and serves as the basis
for subsequent application-specific movement analysis.

The LIMtrack6D 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
