A method of estimating a metric of interest related to the motion of a body

摘要: There is disclosed a computer-implemented method performed in tracking system for the motion of body, as function time, comprising: (a) during first time period, obtaining data related to body from at least one primary positioning unit, wherein said unit mounted on platform carried or separate being operational period; (b) second more secondary sensors configured make measurements which position movement may be determined, platforms body; (c) generating training comprising and data; (d) third sensors, and; (e) analysing estimate metric period using algorithm trained data. A also disclosed.
