METHOD AND DEVICE FOR DETERMINING GEOGRAPHIC POSITIONS OF A GEOGRAPHIC LOCATION TRACER

摘要

The method is implemented by a device (SRV) for a sequence (SQ) of geographic location measurements (Mj) of the tracer (TRAC), the sequence being ordered as a function of a time of measurement of said measurements, the method comprising the steps of: - obtaining (E010) the sequence (SQ); - for a measurement (Mj) of the sequence (SQ), referred to as indexed measurement, - partitioning all the measurements in two ordered sets (E1, E2), the indexed measurement being either the last measurement of the first set (E1) or the first measurement of the second set (E2); - calculating a statistical datum (Med1) for the first set (E1); - calculating a statistical datum (Med2) for the second set (E2); - calculating a distance (Dj), associated with the indexed measurement (Mj), between the sets (E1, E2) as a function of a distance between the statistical data (Med1, Med2) of the sets; - determining a maximum distance (Dmax) among the calculated distances for the set of indexed measurements of said sequence (SQ); the statistical datum (Med1) of the first set (E1) defined for the indexed measurement associated with the maximum difference (Dmax) corresponding to a first position of the tracer and the statistical datum (Med2) of the second set (E2) defined for the indexed measurement associated with the maximum distance corresponding to a second position of the tracer.
