Dynamic Tracking

The C-Track dual-camera sensor is a complete portable 3D measurement solution that offers probing inspection and dynamic measurement capabilities. It is fitted with high-quality optics and special lighting, enabling it to measure all reflectors within its operating space. The probing stylus is very useful for aligning parts with respect to a referential (calculated using a group of reflectors), which allows movement or deformation monitoring directly on the part’s referential.

As its name implies, the C-track tracks the reference model of the whole system, and it ensures the accurate localization of the HandyPROBE portable coordinate measuring machine (PCMM) or the MetraSCAN 3D optical CMM scanners. It performs continuous image acquisition and transmission, lighting of reflectors, management of exchanges with the computer and storage of sensor parameters.

Dynamic tracking is a key component of the TRUaccuracy technology, which guarantees the highest precision there is. Thanks to this feature, the C-Track can be used to measure positions and orientations in space simultaneously and continuously, and with great precision. This makes it possible to control displacements, drive assembly processes or measure deformations.

A software development kit (SDK) has been developed that make interaction possible between the C-Track and other devices such as UT probes. Creaform’s solution replaces 2D encoders by 3D position and orientation measurements to enhance data quality and visualization capabilities.

TRUaccuracy Technology

Ensures highly-accurate measurements, regardless of the measurement environment (instability, vibrations, thermal variation, etc.) or operator skills.


Simultaneous measuring of the set of reflectors, which leads to increased 6 DOF precision (position and orientation).

Complete inspection and dynamic measurement solution

Integrates the HandyPROBE portable coordinate measuring machine (CMM) arm-free probing system and compatible with the MetraSCAN optical CMM 3D scanner.

Passive, wireless, low cost and ultralight reflectors

Reflectors weigh only 1 gram. They are available in adhesive or magnetic versions and 100% compatible with photogrammetric measures (for resetting with a global measure in the case of large equipment).
