RPM refers to Revolutions Per Minute. This controls the speed at which the laser sweeps across the target object. This value can be adjusted to ensure enough frames are captured when the laser is shining on a specific object. This will affect the total time taken to complete a scan and can affect results depending on the ISO and Exposure Time settings.
As a laser scanner which relies on triangulation, the camera is capturing frames at the set speed (depending on Exposure time) whilst the laser is shining on the target object. Our algorithm is then looking for the green laser data in each frame to reconstruct a 3D model.
The rpm value can be set from 1 rpm to 100 rpm.
