Principle is that interpolation knot should be positioned in the middle part of interpolation section as far as possible.According to Lagrangian 3 point interpolation method principles, it is assumed that the registration time
Point is positioned in the middle part of interval, and 3 point estimate in interval are Owing to target is in adjacent scanning
In interval, the difference of displacement is the most little, by 3 moment tk-1、tk、tk+1Be divided into is that equally spaced (interval time is Δ
T), assuming that again the interpolation point time is t, utilizes the Lagrange 3 point interpolation method of document, the measured value calculating t is:
Temporal registration correlation method:
The initial time of known the surveyed data of each measuring unit, end time and measurement frequency.
The time interval measuring frequency with minimum carries out temporal registration for standard, and other measuring units are by Lagrange three
Point interpolation method is at corresponding moment enterprising row interpolation.
Finally give the most corresponding data, prepare for next step data fusion.
