During the scanning process, if the data tracking is lost, how can it be recovered?

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.
