Scanner Sphere & Target

Automatic registration failures are typically caused by poor contrast or laser over-exposure (halos). If a target surface is too glossy, the LiDAR sensor receives irregular intensity returns.

Optimization Checklist:

• Verify distance: Ensure the target size (e.g., OD150mm) is sufficient for the scan resolution at that range.
• Check incident angle: Avoid scanning targets at extreme grazing angles (keep within 45° if possible).
• Surface condition: Ensure the B&W pattern is free of dust, scratches, or moisture.
• Lighting: In pitch-black environments, ensure the scanner's internal or external LED provides enough illumination for the onboard camera.

Choosing between Aluminum and Carbon Fiber depends on your project's precision requirements and environmental conditions.

Material	Stability	น้ำหนัก	Best Application
Aircraft Aluminum	Good (standard)	Standard	General construction, Scan-to-BIM, indoor mapping.
100% Carbon Fiber	Ultra-High (Zero thermal expansion)	Ultra-Light	High-precision monitoring, extreme outdoor heat/cold.
PVC / Self-adhesive	N/A (Temporary)	Negligible	High-volume disposable setups, hard-to-reach walls.

For long-term structural monitoring, Carbon Fiber (N66111 series) is essential because it does not expand or contract significantly with temperature changes, maintaining a constant geometric center.

Mechanical compatibility is only half the battle; the Vertical Center Offset is the critical factor for multi-sensor integration (Total Station + TLS).

Supported Adapter Systems:

• Swiss-Style Spigot: Direct fit for Leica GLS11/12 poles and carriers.
• 5/8" Thread: Universal fit for standard US tripods and prism poles.
• Magnetic Base: Ideal for industrial plants or bridges where tripods cannot be placed.
• Quick-Release: Compatible with Swiss-style quick-lock mechanisms for rapid setup transitions.

A common Reddit "Pro Tip" for scanning: Resolution drops with distance. If your target is too small, there aren't enough points to mathematically calculate the center.

Target Diameter	Optimal Range	Min. Points Required	Verdict
80mm (ST001)	0 – 25 meters	~50 points	Best for Interior/Rooms
150mm (ST003-150)	25 – 60 meters	~50 points	Standard Site Mapping
300mm (ST003-300)	60 – 120+ meters	~50 points	Long-Range Infrastructure

Always ensure you have at least 3 targets visible between scan stations for a robust registration. For distance work, we recommend the ST003 series for its lightweight aluminum disc and high-visibility coating.

Carbon Fiber targets provide ultra-high stability with zero thermal expansion, making them ideal for high-precision monitoring in extreme outdoor conditions. Aircraft Aluminum offers good stability for general use, while PVC is suitable only for temporary setups.

The 86mm standard allows seamless integration with Swiss-Style ecosystems, enabling quick swaps between prisms and scanning targets without re-measuring instrument height. This is critical for multi-sensor workflows involving Total Stations and Terrestrial Laser Scanners.
