FAQ and Troubleshooting
Reconstruction Failure
| Symptom | Possible Cause | Solution |
|---|---|---|
| Complete failure | Footage too blurry | Re-capture, reduce movement speed |
| Complete failure | Pure rotation without translation | Ensure the camera is always moving |
| Complete failure | Video zoom | Lock focal length and re-shoot |
| Partial missing | Insufficient coverage of the area | Supplement multi-angle data for that area |
| Partial missing | No texture in the area (white wall) | Add environmental reference objects or marker points |
Model Artifacts
| Symptom | Possible Cause | Solution |
|---|---|---|
| Ghosting/double images | Moving objects in the scene | Remove moving objects and re-capture |
| Ground holes | Moving shadows | Choose overcast weather or fixed light sources |
| Blurry areas | Motion blur | Reduce movement speed, increase shutter speed |
| Structural distortion | Layered optimization misjudgment (repetitive texture) | Turn off the layered optimization switch |
| Floaters | Lens glare | Avoid backlighting, pass quickly through glare angles |
Incomplete Model
| Symptom | Possible Cause | Solution |
|---|---|---|
| Missing ceiling | No upward shooting | Supplement upward angles |
| Missing floor | No downward shooting | Supplement downward angles |
| Missing corners | Insufficient corner coverage | Pause longer at corners, use multiple angles |
| Broken door frames | Insufficient transition area coverage | Slow down at door frames |
Video Reconstruction-Specific Issues
| Symptom | Possible Cause | Solution |
|---|---|---|
| Unsupported format prompt | Used avi/mkv | Convert to mp4 (H.264) |
| Duration exceeded prompt | Video over 16 minutes | Trim the video or shoot in segments |
| Insufficient resolution prompt | Below 720p | Shoot at a higher resolution |
| Poor reconstruction | Moving too fast | Slow down to 0.5–1 m/s |
| Poor reconstruction | Improper frame rate selection | Choose 4fps for short videos to get more frames |
