Abstract

Le procédé consiste à effectuer un balayage optique résultant de rayons optiques (5) de type laser émis à intervalles réguliers à partir d'une source (2) située au-dessus des personnes (3) ou objets (4) à détecter, les émissions de rayons successives étant réalisées dans un plan de mesure (P) fixe ou mobile, formant un angle nul ou faible par rapport à une perpendiculaire au plan de référence (R) dans lequel se situent et/ou se déplacent les personnes ou objets. La détection est effectuée par détermination et comparaison, pour chaque émission, des décalages temporels observés entre l'émission des rayons optiques (5) par la source (2) et la réception des rayons réfléchis par le plan de "référence" (R) ou par les personnes ou objets. Ce procédé s'applique à la localisation et au comptage de personnes ou d'objets, fixes ou mobiles, ainsi qu'à la définition des caractéristiques de déplacements de personnes.

The method consists in carrying out an optical scan resulting from optical rays (5) of the laser type emitted at regular intervals from a source (2) located above the people (3) or objects (4) to be detected, the emissions of successive rays being produced in a fixed or mobile measurement plane (P), forming a zero or small angle with respect to a perpendicular to the reference plane (R) in which the people or objects are located and / or move. The detection is carried out by determining and comparing, for each emission, the time shifts observed between the emission of the optical rays (5) by the source (2) and the reception of the rays reflected by the "reference" plane (R) or by people or objects. This process applies to the location and counting of people or objects, fixed or mobile, as well as to the definition of the characteristics of movement of people.
