Vision-based vehicle electrical tail door opening method

Abstract

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 than the set threshold value, judging that the action occurs, opening a tail door, and otherwise, judging that no specific action is detected. Compared with the prior art, the vision-based vehicle electrical tail door opening method has the advantages that the cost is lowered, and the identification accuracy rate is high.

Description

Technical field [0001] The invention relates to the technical field of automobile electronics, in particular to a vision-based method for opening an automobile electric tailgate. Background technique [0002] Traditional automobile electric tailgate opening is mainly capacitive, that is, a special capacitor needs to be installed, and the tailgate can be opened only if it is close to the car. The patent with the application number CN201621351899.2 designs a new type of kick-sensing device that automatically opens the tailgate of a car. The device includes a kick-sensing device and an electric tailgate control ECU. The patented kick sensor is based on a capacitive method. People need to stand in a suitable position to kick their feet. It cannot be triggered if it is too close or too far away from the car. It is not sensitive enough. Moreover, the rear bumper is a vulnerable part and the risk of being hit is high. . This kind of electric tailgate opening method has poor recognitio...
