trim_xyzrprh_to_times

HSTB.kluster.fqpr_vessel.trim_xyzrprh_to_times(xyzrph, mintime, maxtime)

Our vessel information (mounting offsets, angles, uncertainty parameters) are stored in the Kluster xyzrph attribute dictionary. Expects a format like this:

{sensor_name1: {utc timestamp1: value, utc timestamp2: value, …},

sensor_name2: {utc timestamp1: value, utc timestamp2: value, …}, …}

This function will trim the provided dictionary to the minimum/maximum time ranges provided. It will keep the nearest earliest timestamped entry, and all entries that fall within the mintime-maxtime range.

Parameters

  • xyzrph (dict) – dict of offsets/angles/tpu parameters from the fqpr instance

  • mintime (float) – minimum time of interest

  • maxtime (float) – maximum time of interest

Returns

xyzrph trimmed to only the relevant entries for this min/max time

Return type

dict
