FreeScan Trak Nova

When mounted on a tripod or stand, the UE Nova serves as the primary tracking head. It utilises a dual-camera system and integrated Video Photogrammetry (VPG) to establish a global coordinate volume. It monitors the spatial position of the handheld scanner in real-time within a tracking range of up to 3.5 metres.

The TE Nova is the agile, handheld component that the operator moves over the part. It is equipped with optical tracking targets that are constantly "seen" and triangulated by the UE Nova's cameras. Because the UE Nova knows exactly where the TE Nova is in 3D space, it can "stitch" the high-density laser data into the global coordinate system without requiring a single marker on the part itself.

In a standard industrial environment, vibrations from nearby machinery or slight movements of the part would normally ruin a scan. The UE Nova and TE Nova solve this through Dynamic Tracking:

• Coordinate Locking: The UE Nova monitors the relationship between its own position, the TE Nova, and a set of "leapfrog" markers or a calibration rod on the part.
• Real-Time Compensation: If the part moves, or if the tracking head itself is bumped, the system recalculates the spatial relationship at high frequency. The scan data remains accurate and aligned because the "tracking" is absolute to the part’s frame of reference, not the floor's.

One of the most significant advantages for the end-user is the ability to swap roles between the units to balance Information Gain with Speed.

• Wide-Range Global Scan: For massive structures (e.g., a 7-metre truck bed or a turbine housing), the UE Nova can be detached and used as a standalone handheld laser scanner. It utilizes its massive 2.6 x 2.2 m Field of View (FOV) to rapidly capture the overall structure and global dimensions.
• High-Detail Local Scan: Once the "global mesh" is established, the operator switches to the TE Nova. Using its 7 parallel blue laser lines, it captures intricate features, sharp edges, and deep pockets at a much higher resolution (down to 0.01 mm).
• Seamless Fusion: The EXScan software then fuses these two datasets. The large-scale data from the UE Nova provides the "skeleton," while the high-precision data from the TE Nova provides the "skin" for critical tolerance areas, creating a unified, metrology-grade dataset without redundant setups.
