• Auxiliary Fiducial Markers requires at least one marker at every FOV, while hybrid alignment only necessitates markers in areas with insufficient geometric features. Theoretically, the former requires more markers than the latter.
• Auxiliary Fiducial Markers prioritizes marker detection first in order to prevent geometric feature misalignment. While Hybrid Alignment recognizes texture first, then geometry, markers the last.

1. Select “Edit Scan Data”（Access the scan data editing module）

2. Click “Edit”（Identify floating/sub-mesh datasets）

3. Select target primary mesh → Click the “①” button

Retain only the designated principal mesh

Result: Non-selected secondary mesh data will be permanently deleted.

1. Navigate to the “Display” interface in the left-side floating panel
2. Uncheck the “Custom Textures” option

Case 1: When the panel completely disappears from interface
▸ Right-click on the menu bar area (marked by red box)
▸ Select “Workflow” from the pop-up context menu

Case 2: When the panel floats as a detached window
▸ Double-left-click on the title bar of the floating “Workflow” panel (marked by red box)

• A “click” sound indicates successful fastening. Always ensure the controller is securely fastened before lifting and using the device to prevent accidental detachment and potential damage from falls.
• When using the wireless controller, always securely attach the safety strap. This prevents the device from falling and breaking due to detachment without protection.
• Avoid placing the controller on its side with buttons facing down to prevent accidental button presses. When lifting the device from a surface, always verify the connection status between the controller and scanning hardware. Only lift the device after confirming it is securely locked in place.

• First, check if the computer meets the requirements of NVIDIA dedicated graphics card Task Manager – Performance -GPU (Generally, dedicated graphics cards are GPU1, so check GPU1 first. If there is no GPU1, then look at GPU0).

• If there is no NVIDIA dedicated graphics card, the computer configuration needs to be The recommended configuration is as follows:

Under the condition of having a NVIDIA independent graphics card that meets the requirements, the reasons for the absence of the dll file are as follows:

① The driver was not installed or updated correctly.

② The operating system files were damaged.

③ The system files were lost due to virus or malicious software attacks.

④ The user manually or through certain cleaning software mistakenly deleted the key system files.

The nvml.dll file needs to be installed manually or imported.

For hybrid alignment:

Causes:

1. Scanner moved too quickly, resulting in insufficient feature overlap between frames
2. Improper scanning distance (too close/far), causing feature recognition failure by the cameras

Solutions:

1. Return to a previously scanned area while maintaining the optimal scanning distance
2. Pause for 2 seconds to allow the scanner to recognize features and re-establish alignment

Note:

• Begin with feature-rich areas for the first frame to establish a strong reference.
• Pause scanning if alignment fails for >5 seconds, reposition the scanner topreviously captured areas with clear features and resume scanning.

For marker mode:

Causes: Insufficient markers / Marker degradation / Overly regular marker arrangement

Solutions:

1. Add several markers in sparse areas and continue scanning, though with reduced positional accuracy. For better results, initiate a new scan with properly distributed markers.
2. Remove worn-out markers with alcohol swabs, and replace with new ones.
3. Rearrange the existing markers to avoid overly regular placement.

The method and steps for calibrating white balance are as follows:

1. Take out the gray card from the case and position it face-up on a light-color surface.
2. Select the “White Balance Calibration ” function on the left, and process the calibration following the on-screen instructions, as shown in Figure 6-3.
3. Align the scanner perpendicularly to the gray card surface, adjust the distance until the position indicator enters the yellow target frame on the user interface.
4. Maintain a vertical standoff distance of 300 mm between the scanner and the gray card.

Note: In which situations is white balance calibration required?

• Environmental Change Between Scans (e.g., outdoor-to-indoor transition).
• Color Deviations (e.g., significant hue/saturation deviation during real-time preview)
• Complex Ambient Lighting (e.g., Mixed artificial light sources (e.g., red/green dominant illumination)

The dual black-and-white cameras are mounted at a specific angle to each other, and the optimal scanning angle occurs when both cameras can detect the target object at near-vertical incidence angles. Point B yields the highest point cloud density, while points A and C produce the sparsest data. For challenging areas or dead zones, the scanner can be re-positioned to ensure simultaneous object visibility by both cameras.

For optimal scanning results, maintain a working distance between 200mm and 400mm to achieve the highest point cloud quality and finest detail resolution.

Optimal scanning distance of Infrared Structured Light Scan: 300 mm

Optimal scanning distance of Infrared Laser: 300 mm

Optimal scanning distance of Blue Laser: 210 mm

Select Infrared Laser and Marker Mode in scanning mode, and click settings to enable Color Camera Fill Light. When the option is turned on, the maximum scanning frame rate will drop from 70 FPS to 30 FPS.

For objects with limited geometric features and uniform coloration (e.g., car doors), markers must be applied to featureless areas (e.g., flat surfaces) to facilitate scanning and alignment.

Note: To scan objects using markers with hybrid alignment, enable the Laser Fill Light in Scan Mode > Settings > Switch

This advanced mode enables simultaneous recognition of:

• Geometric features(surface contours/edges)
• Texture features(natural patterns)
• Markers(when applied)

The hybrid alignment mode improves scanning performance through:

• Enhanced alignment accuracy
• Reduced marker dependency(enabling scans with:

1. Zero markers for textured objects
2. 3-5 markers for low-feature surfaces)
