Abstract

L'invention concerne un système d'analyse (1) comprenant : un dispositif de collecte de données (10) monté sur un corps mobile (V) et qui collecte des données d'analyse comprenant des données d'image et des données d'emplacement, les données d'image représentant des images de l'extérieur du corps mobile (V) capturées en association avec le mouvement du corps mobile (V), et les données d'emplacement représentant les emplacements de capture des images de l'extérieur du corps mobile (V) ; et un dispositif d'analyse de données (20) qui, en fonction des données d'analyse collectées par le dispositif de collecte de données (10), compte le nombre de personnes qui passent des points spécifiques sur le trajet de déplacement du corps mobile (V). Le système d'analyse (1) peut ainsi analyser correctement des tendances dans des flux de personnes.
