Incomplete lines when reducing angle aperture

Hardware
1

Hello,

when reducing the angle aperture of an OS0-128-SR from Ouster Studio, the lines at the edges of the aperture look a bit irregular, staggered, as in the attached picture.

Is that normal? What is that caused by?

Here, the aperture was set from 210 to 140, but at those angles the point clouds look incomplete, would it be reccomended to set the angle limits a bit larger than the required ones?

Thank you very much.

Best,
Marco

Hi Marco,
I don’t think your picture attached unfortunately.
Based on your description, it sounds like you are reducing the field of view from a full 360 to a partial 70 degree scan. Did you modify the Azimuth Window angles in the sensor?

Here are the settings displayed in the sensor webpage

If yes, then this staggered-ness is expected. You can read more about this: Lidar Scan API — Ouster Sensor SDK 0.15.0 documentation
