| description | The invention relates to a vision-based vehicle electrical tail door opening method. The vision-based vehicle electrical tail door opening method is used for conducting identification on specific actions of a person outside a vehicle so that whether an electrical tail door is opened or not can be judged. The method comprises the steps of 1, obtaining video of the specific actions of the person outside the vehicle as training data in advance through a vehicle-mounted all-round camera; 2, conducting preprocessing and feature extraction, and obtaining a training action element sequence; 3, starting the vehicle-mounted all-round camera to shoot and process the current action; 4, obtaining an action feature sequence from a current video image, and calculating a current action sequence; 5, matching the current action sequence with the training action element sequence, and obtaining the mean distance of the two sequences; and 6, comparing the mean distance with a set threshold value, if the mean distance is less tha |
