Maximum Time and Maximum Speed
The maximum time and speed refer to the tracking parameters. The maximum time specifies the
maximum elapsed time between two acquired positions to validate the path between these two
positions. Typically, 1 s maximum elapsed time is appropriate.
The maximum speed specifies the maximum speed for a segment path to be valid. A maximum
scanning speed of 0.5 m/s is required by ISO 9614-2.
Averaging Distance and Maximum Interpolation Distance
The averaging distance sets the averaging radius for Gaussian averaging of the sound map. Set to
zero to disable averaging. The maximum interpolation distance defines the maximum distance
between two measurement points to interpolate data between these points.
