Defining The Resolution - Leica ScanStation P30 Basic Training Manual

Defining the Resolution

In the Resolution tab there are two different EDM modes available: Speed and Range.
Speed is used as a default setting with a range of 120m.
Range is used for the extended range of 270m. (P40 only)
There are seven pre-defined resolution settings available. You can choose one of them with the
slider, or the + and – symbols and the value is shown in the text above the slider.
The resolution is based on a distance of 10m and restricted to the seven resolution steps with
0.8mm as the highest step and then doubled to 1.6mm, up to 50mm. Therefore these steps
cannot be adjusted by the user, e.g. as a user defined resolution, but the resolution on far away
objects can then easily be calculated by the intercept theorems.

There are also the two steps of the Sensitivity settings, that can be adjust like the resolution
with the slider or the +/- symbols. In the following spread sheets the scanning time is listed,
which is a result of the Sensitivity settings in dependence to the resolution. As the spread sheet
shows, a setting to a higher quality level will increase the scanning time:
Speed Mode (Target All) Range Mode (Target All)

The higher the selected Sensitivity the more range measurements for the same 3D point are
collected (Accumulation). This reduces the range noise.
