Abstract
(EN)
Embodiments of the present invention provide a vehicle detection method and device. The vehicle detection method comprises: obtaining an image to be processed and depth information of each pixel point in said image; obtaining a distance value of a vehicle candidate region in said image according to said image and the depth information; and determining, according to the distance value of the vehicle candidate region, a detection model corresponding to the vehicle candidate region. Vehicles can be detected using different detection models according to different distances, thereby improving the accuracy and reliability of vehicle detection, and reducing the probability of false detection and missed detection.
(FR)
La présente invention concerne, dans des modes de réalisation, un procédé et un dispositif de détection de véhicule. Le procédé de détection de véhicule comprend les étapes consistant à : obtenir une image à traiter et des informations de profondeur de chaque point de pixel dans ladite image; obtenir une valeur de distance d'une région candidate de véhicule dans ladite image selon ladite image et les informations de profondeur; et déterminer, en fonction de la valeur de distance de la région candidate de véhicule, un modèle de détection correspondant à la région candidate de véhicule. Des véhicules peuvent être détectés à l'aide de différents modèles de détection selon différentes distances, ce qui permet d'améliorer la précision et la fiabilité de la détection de véhicule, et de réduire la probabilité de fausse détection et de détection manquée.
