Problem
Wave-like stripes, spanning globally and perpendicular to the camera’s baseline direction, can be observed in the point cloud.
Scrrenshot of point cloud:
Problem Analysis
- This type of global point cloud fluctuation commonly occurs in exhibition halls or workspaces with LED light sources positioned overhead, with the lights effectively covering the entire scene.
- The wave-like stripes span globally and exhibit uniform fluctuations.
- The primary issue arises from the environmental impact of lighting, necessitating the implementation of corresponding anti-flicker functionality.
Solution
Select “Expert” for “Visibility”, go to “3D Parameters” → “Anti-Flicker Mode”, and select AC50 Hz or AC60Hz according to specific situation.

Difference between 50Hz and 60Hz
| Region | PRO/NANO | Other Cameras | |
|---|---|---|---|
| 50Hz AC Power: Europe | “Anti-Flicker Mode”-“AC50Hz” | 3D exposure set at multiples of 10ms | |
| 60Hz AC Power: United States, South Korea, etc. | “Anti-Flicker Mode”-“AC60Hz” | 3D exposure set at multiples of 8.3ms |
