Abstract
(EN) An inertial device having sensors operable to output accelerations in a horizontal and a vertical direction is disclosed that includes a detection unit configured to detect a turning point in a waveform representing the acceleration in the vertical direction with respect to time and to detect time at the turning point; a calculation unit configured to calculate a velocity in the horizontal direction using the acceleration in the horizontal direction in a predetermined period centering on the time at the turning point; a determination unit configured to determine whether the velocity is less than or equal to a threshold value; and an estimation unit configured to estimate a direction to which a target having the inertial device moves using the velocity in response to a determination by the determination unit that the velocity is less than or equal to the threshold value.
(FR) La présente invention porte sur un dispositif inertiel ayant des capteurs aptes à être mis en œuvre pour délivrer en sortie des accélérations dans une direction horizontale et une direction verticale, qui comprend une unité de détection configurée pour détecter un point de retournement dans une forme d'onde représentant l'accélération dans la direction verticale par rapport au temps et pour détecter un temps au niveau du point de retournement ; une unité de calcul configurée pour calculer une vitesse dans la direction horizontale à l'aide de l'accélération dans la direction horizontale dans une période prédéterminée se centrant sur le temps au niveau du point de retournement ; une unité de détermination configurée pour déterminer si la vitesse est inférieure ou égale à une valeur seuil ; et une unité d'estimation configurée pour estimer une direction vers laquelle une cible ayant le dispositif inertiel se déplace à l'aide de la vitesse en réponse à une détermination par l'unité de détermination que la vitesse est inférieure ou égale à la valeur seuil.
