FreeScan Trak ProW+ for Geometric Inspection of Large Objects
Shining 3D FreeScan Trak ProW+ — is a wireless dynamic 3D tracking and scanning system for metrology-grade measurements of large parts and objects. The tracker determines the position of the handheld 3D scanner in real time, so reference markers do not need to be applied directly to the part during dynamic tracking. The tracking volume from a single position reaches 156 m³, while the maximum tracking distance is 8.6 m. Integrated computing and wireless modules provide real-time data processing and wireless transmission, giving the operator greater freedom when moving around a large object.
Key Advantages of FreeScan Trak ProW+
- Accurate metrology-grade measurements. FreeScan Trak ProW+ enables geometric inspection of parts in applications with high measurement accuracy requirements. The system accuracy is 0.023 mm.
- Large tracking volume. The system enables large objects to be measured with fewer tracker repositionings. The expanded tracking range covers a working volume of up to 156 m³ from a single position, while the maximum tracking distance is 8.6 m.
- High data acquisition speed. The scanner reduces the time required to digitize large surfaces and parts with complex geometries. High-speed scanning uses 93 crossed laser lines, with a scanning speed of up to 7 600 000 points/s.
- Fewer preparation steps before scanning. During dynamic tracking, the operator does not need to apply reference markers directly to the measured part. The tracker recognizes the scanner and determines its position in real time.
- Convenient movement around the object. Wireless operation reduces restrictions on the operator when scanning large parts. FreeScan Trak ProW+ features integrated computing and wireless modules that provide real-time data processing and stable wireless transmission.
- Adaptation to different surface geometries. Multiple scanning modes make it possible to select the data acquisition method according to the shape and accessibility of the measured area. The system uses 93 crossed laser lines for high-speed scanning, 25 parallel laser lines for detailed scanning, and 1 laser line for deep-hole scanning.
- Volumetric accuracy control when measuring large objects. Video photogrammetry helps maintain accuracy across a large measurement volume. VPG technology works together with a calibration bar and verifies markers using video data without coded markers. Volumetric accuracy with VPG is 0.044 mm + 0.012 mm/m.
Tracking Large Objects up to 156 m³
FreeScan Trak ProW+ has a maximum tracking distance of 8.6 m and covers up to 156 m³ from a single position. The large tracking volume makes it possible to measure a significant portion of a large object without frequently repositioning the tracker. If the dimensions of the object exceed the available tracking volume, the system can be moved to another position. During repositioning, common reference geometric features are measured again to link the new system position to the original coordinate system. This process is referred to as leapfrog in SHINING 3D's official materials. The expanded tracking volume of FreeScan Trak ProW+ reduces the need for such repositioning.
Marker-Free Scanning
During dynamic tracking, the tracker recognizes the handheld scanner and determines its position in real time. As a result, reference markers do not need to be applied directly to the surface of the part. This approach reduces measurement preparation time, which is particularly important when working with large objects. The absence of a requirement to apply markers refers specifically to system operation in dynamic tracking mode. It does not mean that markers are not used in other supported measurement methods, including VPG.
Laser 3D Scanning Modes
- High-speed scanning. This mode is designed for rapid surface data acquisition and uses 93 crossed laser lines. It enables faster digitization of large surface areas.
- Detailed scanning. This mode is used for areas where more detailed surface geometry acquisition is required. Scanning is performed using 25 parallel laser lines.
- Deep-hole scanning. This mode is designed to capture the geometry of areas that are more difficult to reach with a multi-line laser pattern. FreeScan Trak ProW+ uses 1 laser line for this purpose.
Wireless 3D Scanning
FreeScan Trak ProW+ is equipped with integrated computing and wireless modules. This architecture enables cable-free scanning, real-time data processing, and wireless data transmission. It simplifies operator movement around large parts. The integrated display provides quick access to key device information directly during operation.
VPG Video Photogrammetry
FreeScan Trak ProW+ uses SHINING 3D's patented VPG video photogrammetry technology. It helps accurately determine marker positions when scanning large objects and works with a calibration bar. Coded markers are not required for VPG operation. Volumetric accuracy with VPG is 0.044 mm + 0.012 mm/m. This makes it possible to maintain measurement accuracy when scanning large parts and objects.
Measurement Accuracy Depending on Working Volume
| Working Volume | Distance | Volumetric Accuracy |
| 12 m³ | 3.5 m | 0.046 mm |
| 36 m³ | 5 m | 0.063 mm |
| 60 m³ | 6 m | 0.088 mm |
| 100 m³ | 7.2 m | 0.125 mm |
| 156 m³ | 8.6 m | 0.156 mm |
As the distance and working volume increase, the volumetric accuracy of the system changes. For a 12 m³ volume at a distance of 3.5 m, it is 0.046 mm, while for the maximum 156 m³ volume at a distance of 8.6 m, the value is 0.156 mm.
FreeProbe Contact Measurements
FreeProbe Series is optional equipment for FreeScan Trak ProW+ and is not included in the standard package. FreeProbe can be used to measure points in hard-to-reach areas that are difficult to scan. To take a measurement, the operator simply touches the required point on the part with the probe tip. FreeProbe operates wirelessly, while the system tracks its position in real time. During operation, the operator can freely move the part, FreeProbe, and tracker without recalibration.
