Title
(EN) ADAPTIVE ADJUSTMENT METHOD AND DEVICE FOR REAR-VIEW MIRROR
(FR) PROCÉDÉ ET DISPOSITIF DE RÉGLAGE ADAPTATIF POUR RÉTROVISEUR
(ZH) 后视镜自适应调节方法及装置
Abstract
(EN)
An adaptive adjustment method for a rear-view mirror, comprising: acquiring the space position of driver's eyes and the space position of a target rear-view mirror of the host vehicle, and acquiring a horizontal field-of-view angle of the driver in the target rear-view mirror according to the space position of the eyes and the space position of the target rear-view mirror; acquiring images of vehicles behind, and acquiring a first auxiliary angle of a target vehicle behind according to the images of the vehicles behind; obtaining a second auxiliary angle by calculation according to the horizontal field-of-view angle, the space position of the eyes and the position of the target rear-view mirror; acquiring a horizontal adjustment angle of the target rear-view mirror according to the first auxiliary angle and the second auxiliary angle; and adjusting a horizontal angle of the target rear-view mirror according to the horizontal adjustment angle. Disclosed is an adaptive adjustment device for a rear-view mirror. The adaptive adjustment method and device for a rear-view mirror avoid the effect on the driving safety due to the distraction of a driver caused by manual adjustment of the rear-view mirror.
(FR)
La présente invention concerne un procédé de réglage adaptatif pour un rétroviseur comprenant les étapes consistant à : acquérir la position spatiale des yeux du conducteur et la position spatiale d'un rétroviseur cible du véhicule hôte, et acquérir un angle de champ de vision horizontal du conducteur dans le rétroviseur cible en fonction de la position spatiale des yeux et de la position spatiale du rétroviseur cible ; acquérir des images de véhicules derrière, et acquérir un premier angle auxiliaire d'un véhicule cible derrière, en fonction des images des véhicules derrière ; obtenir un second angle auxiliaire par calcul selon l'angle de champ de vision horizontal, la position spatiale des yeux et la position du rétroviseur cible ; acquérir un angle de réglage horizontal du rétroviseur cible selon le premier angle auxiliaire et le second angle auxiliaire ; et régler un angle horizontal du rétroviseur cible selon l'angle de réglage horizontal. La présente invention concerne un dispositif de réglage adaptatif pour un rétroviseur. Le procédé et le dispositif de réglage adaptatif pour un rétroviseur évitent l'effet sur la sécurité de conduite en raison de la distraction d'un conducteur provoquée par un réglage manuel du rétroviseur.
