Method for encoding motion sensor data, and associated device and system

A method for encoding data generated by one or several movement sensors coupled to a moving entity, for the identification of a position or movement of the moving entity on a time sequence,

• said method, executed by one or several processors, including:
• a step of acquiring data generated by the movement sensor(s) coupled to the moving entity, said data including variable values in the form of time series;
• a step of calculating, from the data acquired over a time window, a plurality of descriptors, the calculating step being repeated for several consecutive time windows, the consecutive time windows forming the time sequence;
• and
• a step of transforming the plurality of descriptors of each of the consecutive time windows forming the time sequence,
• said transforming step including a generation, for each of the descriptors, of first data coded on at most eight bits,
• said first data coded on at most eight bits associated with the time sequence being representative of a position or movement of the moving entity on said time sequence.
