LiDAR/3D Scanner
A LiDAR or 3D scanner is employed to generate a three-dimensional model of instruments, structures, or the body within specialized software. This model is utilized to conduct simulations, among other applications.
Pre-scanning checklist
- System requirements:
- Know the system requirements. Before setting up the LiDAR scanner, make sure your computer meets the minimum processor and graphics card requirements needed to run the scanner software.
- Connection with device :
- Connecting with laptop (RECOMMENDED): To connect to a laptop, use the cables provided with the scanners.
- Connecting with phone : (1) The scanner and phone should be connected to the same WiFi. (2) Visit the scanner's application to verify the connection with the device.
Before scanning
- Choose a New Project
- Check Camera setting/exposure :
- Open live camera view before scanning
- Exposure indicator :
- Green = Proper exposure.
- Red = Lost track of exposure (Proceed to the location where the scanning process was halted.).
- Adjust lighting if needed for the settings.
- Tracking Method :
- Geometry Mode :
- Uses the object's shape for tracking.
- Recommended for objects with little surface texture.
- Texture Mode:
- Relies on visible surface patterns.
- Better for highly textured objects.
Scanning Technique
- Maintain approx. 60 cm of distance between the scanner and the object.
- Avoid moving too close because it reduces tracking quality.
- Moving too far away leads to higher chances of losing tracking performance.
- The recommended scanning technique is to scan the object from multiple angles.
- Avoid quick or jerky motions, as it will lead to losing track of the motion.
- Continuously move around the object instead of making sudden direction changes.
- The scanner builds a 3D map while moving, so smooth motion helps maintain tracking.
Anchoring Points
Begin scanning from a distinctive point. For example, for scanning the 2D-S instrument, scan from the top-semispherical part.
Good anchor points :
- A unique end or feature
- Returning to an anchor point can help the scanner recover if tracking is lost.
If Tracking Lost(SLIP)
To Recover:
- Return to previously scanned area
- Move slowly until tracking resumes
- Continue scanning from that location.
IR Reflective Markers
If tracking repeatedly fails:
- Apply IR reflective marker stickers around the object.
- Switch the tracking mode from Point Cloud to Global Marker.
- Markers provide additional reference points for the scanner.
Saving the scan
- If the scan contains major slipping or distortion, discard it and rescan.
- Save scans only when the object has been reconstructed correctly.
