Title: METHOD FOR ESTIMATING THE LOCATION OF A DEVICE, AND CORRESPONDING MODULE, DEVICE, COMPUTER PROGRAM PRODUCT AND STORAGE MEDIUM
Abstract:
The invention concerns a method for estimating the current location L i of a device Equip associated with a sensor Capt, in a known environment, the method being characterised in that it comprises an iteration of the following steps: obtaining (100) an item of data s i of said sensor Capt, at said location L i ; determining (110) a prediction p j of an item of sensor data for each of the N candidate locations C j , j=1 to N>1, previously selected, said determination taking account of the known environment and a movement mv i previously defined for said device Equip from a preceding location L i-1 ·; calculating (120) a similarity S j between said item of sensor data s i and said prediction p j ; selecting (130) the m best candidate locations C j resulting from said calculation of similarity in order to estimate said location L i , m < N.
