Overview
FreeScan Trak ProW+ is a wireless 3D dynamic tracking and scanning system for large‑scale industrial metrology. It provides marker‑free wireless scanning, integrated video photogrammetry (VPG) for volumetric verification, optional FreeProbe compatibility for contact measurements, and verified metrological accuracy according to VDI/VDE 2634 and ISO 10360.

Highlights

• Marker‑free wireless scanning with dynamic tracker recognition
• Max. 8.6 m tracking distance and up to 156 m³ single‑station tracking volume
• Integrated Video Photogrammetry (VPG) for volumetric accuracy without coded markers
• Optional FreeProbe contact probe for hard‑to‑reach features
• Verified accuracy (VDI/VDE 2634 & ISO 10360)

Key features

• No markers required on the part: tracker recognizes the scanner via targets on the device, simplifying setup for large objects.
• High throughput scanning: up to 7,600,000 points/s (ProW+) for rapid data capture.
• Three scan modes: High‑speed, Detailed, Deep‑pocket to adapt to part geometry and measurement objectives.
• Wireless operation with integrated computing, stable wireless transmission and an onboard display for status and parameters.
• Compatible metrology accessories (Metrology Pro Kit, turntables, marker/leapfrog options) to extend workflows.

Ultra‑wide measuring range
With an 8.6 m tracking distance and a single‑station volume up to 156 m³, the system reduces the need for leapfrog repositioning when scanning large assemblies, improving on‑site efficiency.

Wireless scanning & workflow
Integrated compute and wireless modules enable cable‑free scanning and real‑time processing. The built‑in display provides immediate device information, while support for power banks enables flexible field operation.

Video Photogrammetry (VPG)
Patented video‑based photogrammetry integrates video capture and a calibration rod to verify marker positions in real time, removing the need for coded targets and ensuring consistent volumetric accuracy across large scans.

FreeProbe series (optional)
FreeProbe probes provide contact measurement capability for features inaccessible to optical scanning, enabling hybrid workflows for inspection and reverse engineering with high pinpoint accuracy.

Software & capabilities

• Real‑time data quality visualization during capture.
• Intelligent resolution: automatic mesh resolution adjustment by curvature.
• AI feature recognition for holes, slots and boundaries to accelerate measurement setup.
• Inspection module with metrology workflows (PTB‑referenced) and compatibility with major inspection and reverse‑engineering software.
