Setting resolution and quality
Resolution – The resulting scan resolution. You can choose among 1/1, 1/2, 1/4, 1/5, 1/8, 1/10,
1/16, 1/20 and 1/32. Use the slider on the left to change the resolution of the next scan.
Quality – Affects the quality of the scan and the scanning time at constant scan resolutions. Move
the slider up to reduce the noise in the scan data and increases the scan quality. This results in a
longer scanning time. Move the slider down to reduce the scanning time and increase the efficiency
of your scan project. The Quality slider sets quality levels either via diverse measurement rates or by
applying additional noise compression. For more information, see Scanning parameters overview,
page 51.
The resulting scan duration, vertical and horizontal scan points (Scan Size [Pt]), as well as the
resulting scan size in Mega points (MPts) are displayed in the middle of the view. Point Distance
[mm/10m] / [in/30ft] is the distance between the captured scan points in mm (in) in a scan distance
of 10 meters (30 ft.).
Depending on the chosen scan resolution only appropriate quality values are selectable (see
Scanning parameters overview, page 51).
If you plan to capture several scans from the same position (with different resolutions) and if it is
important that these scans have the same horizontal start angle, then you should not switch off the
scanner or change the quality between the recordings of these scans.
