Title
(EN) SYSTEM AND METHOD FOR FUSING ASYNCHRONOUS SENSOR TRACKS IN A TRACK FUSION APPLICATION
(FR) SYSTÈME ET PROCÉDÉ DE FUSION DE PISTES DE CAPTEURS ASYNCHRONES DANS UNE APPLICATION DE FUSION DE PISTES
Abstract
(EN)
An example method can include receiving, at a sensor, a signal associated with a motion of a target, processing the signal via a first filter having a first motion model and a second filter having a second motion model to yield a first tracking output and a second tracking output for the target, and weighting the first tracking output and second tracking output according to how well each of the first motion model and second motion model represents the motion of the target, to yield a first weight for the first tracking output and a second weight for the second tracking output. The method can include combining the first tracking output and second tracking output to yield a fused tracking output and sending, to a fusion system, the fused tracking output, the first weight associated with the first tracking output and the second weight associated with the second tracking output.

La présente invention concerne un procédé, donné à titre d'exemple, pouvant comprendre la réception, par un capteur, d'un signal associé au déplacement d'une cible, le traitement du signal par l'intermédiaire d'un premier filtre ayant un premier modèle de déplacement et d'un second filtre ayant un second modèle de déplacement pour donner une première sortie de suivi et une seconde sortie de suivi pour la cible, et la pondération de la première sortie de suivi et de la seconde sortie de suivi en fonction de la manière dont le premier modèle de déplacement et le second modèle de déplacement représentent le déplacement de la cible, pour donner un premier poids à la première sortie de suivi et un second poids à la seconde sortie de suivi. Le procédé peut comprendre la combinaison de la première sortie de suivi et de la seconde sortie de suivi pour produire une sortie de suivi fusionnée et l'envoi, à un système de fusion, de la sortie de suivi fusionnée, du premier poids associé à la première sortie de suivi et du second poids associé à la seconde sortie de suivi.
