Physics, Astronomy & Cosmology / How can I calculate displacement from time series acceleration data?
« on: 07/06/2006 08:26:04 »
Hi,
Does any one have a simple algorithm for translating time series acceleration data to displacement. All any one ever seems to have is "just double integrate the data" ...... double integrate what?
I also understand that this process results in drift of the result, this isn't so important to me as I am recording accelerations from a bouy to record wave height, and all im interested in is the mean wave height of the data series.
The data is recorded from a simple single axis accelerometer and resulting in the following data:
Time ; Acceleration in m/s^2
at a frequency of 20Hz - although this can be changed.
Any Ideas of VB code samples would be great.
