1. A method for determining paths of individuals in a place having zones equipped with means for detecting individuals, and some of which are inaccessible directly from other zones, the detection means being connected to a computerised processing unit incorporating a topography of the place and a time model comparing a travel time and at least one possible path between the zones, the method comprising the steps of,
storing in the computer unit initial events each associating a detection of the representative characteristics of an individual in a first zone and temporal detection information, listing in the computer unit subsequent events each associating a detection of representative characteristics of an individual in another one of the zones of the place and temporal detection information, reconstituting in the computer unit a path of each individual in the place from the first zone by aggregating events subsequent to each initial event by comparing representative characteristics of each subsequent event with representative characteristics of each initial event, and checking consistency of the paths of the individuals from one zone to another from the topography of the place, the time model and temporal detection information, when at least one subsequent event, referred to as residual, has not been able to be aggregated in a path, the method comprises the subsequent steps of: identifying reconstituted paths considered to be incomplete from the topography of the place, determining a probability that the residual subsequent event follows the last subsequent event of each reconstituted path considered to be incomplete and aggregating the residual subsequent event with one of the reconstituted paths according to this probability. |
