Scanning Tips
Best practices for capturing high-quality 3D scans
Scanning Tips
Follow these tips to get the best results from your PortalCam.
Lighting
Ideal Conditions
- Natural daylight — Open curtains and blinds
- Even lighting — Avoid harsh shadows
- Consistent brightness — Similar levels throughout the space
Avoid
- ❌ Direct sunlight on the lens
- ❌ Very dark rooms
- ❌ Flickering lights
- ❌ Dramatic lighting changes mid-scan
If a room is too dark, turn on all available lights. Consistent artificial lighting works well.
Movement
Best Practices
- Walk slowly — Half your normal pace
- Keep camera level — The app shows orientation guides
- Smooth movements — Avoid jerky motion
- Pause at doorways — Ensure good overlap between rooms
Avoid
- ❌ Running or fast walking
- ❌ Tilting the camera dramatically
- ❌ Spinning in place
- ❌ Sudden direction changes
Coverage
Overlap is Key
For best quality, capture areas from multiple angles:
- Walk through the same areas twice from different directions
- Scan corners from both adjacent walls
- Capture doorways from inside and outside the room
Don't Miss
- Ceiling details (angle up briefly if needed)
- Floor surfaces
- Corners and edges
- Areas behind furniture (if accessible)
Environment
Prepare the Space
Before scanning:
- Remove moving objects — Pets, people, fans
- Close doors to rooms you don't want
- Turn off TVs — Moving images cause artifacts
- Secure loose items — Curtains, papers, etc.
Challenging Surfaces
Some surfaces are difficult for any 3D scanner:
| Surface | Issue | Solution |
|---|---|---|
| Mirrors | Reflections confuse LiDAR | Cover or accept artifacts |
| Glass | Transparent to LiDAR | Capture at angle if possible |
| Black surfaces | Low reflectivity | Add ambient lighting |
| White walls | Low texture | Include furniture/objects |
Room-by-Room
Small Rooms (Bathrooms, Closets)
- Stand in the doorway initially
- Move slowly around the perimeter
- Capture 360° from the center
Large Rooms (Living Areas)
- Use overlapping zigzag pattern
- Make multiple passes at different heights
- Ensure corners are captured from both sides
Hallways
- Walk the length slowly
- Pause at each doorway
- Capture in both directions if possible
Stairs
- Ascend slowly while scanning
- Pause at landings
- Consider doing a second pass descending
Quality Checklist
Before ending your scan:
- All rooms covered (check app preview)
- No large gaps in coverage
- Corners and edges captured
- Doorways scanned from both sides
- Good lighting throughout
Troubleshooting Poor Results
| Issue | Likely Cause | Fix |
|---|---|---|
| Blurry areas | Moving too fast | Rescan slowly |
| Missing sections | Incomplete coverage | Add overlapping passes |
| Floating artifacts | Reflective surfaces | Cover mirrors/glass |
| Misaligned rooms | Insufficient overlap | Scan doorways thoroughly |
| Dark regions | Poor lighting | Add lights, open blinds |
