New Arrival Auto Power Boot Eletronic Tailgate System for Toyota Sequoia
Introduction of tailgate system based on motion recognition
1.1 Introduction of electric induction tailgate
|
The electric tailgate system includes a variety of opening and closing methods, such as intelligent key opening and closing and inductive opening and closing. The inductive opening and closing function is suitable for the case where there are too many objects in hand and it is not convenient to manually or use the smart key to open the tailgate. When the driver carries the key close to the rear of the vehicle and swipes the sensing area with his foot, the electric tailgate switch can be triggered , Control the opening and closing of the tailgate, easy and fast to store objects in the vehicle.

1.2 Induction tailgate system based on motion recognition
|
The system includes a detection algorithm based on motion recognition and a tailgate control system suitable for vehicle-mounted platforms. When the person carrying the key approaches the car, the rear-view camera is turned on to collect human movements, and the similarity between the current movement and the target movement is calculated in real time through the detection algorithm. If the similarity is less than the set threshold, the movement is considered detected, and the The tail gate sends out a control signal to open the tail gate.

1.3 Motion Recognition Algorithm
|
The computer vision-based action recognition algorithm used by the system mainly includes three main links: action area detection and positioning, feature extraction and action matching.
First, pre-process the image collected by the car camera, and also remove the noise and shadow caused by the light in the image. Then, use the background subtraction method, human detection and tracking methods to locate the human movement, and use the external connection obtained by the positioning The rectangle serves as an action interest area, and action feature information is extracted in this area.

Action feature representation methods are mainly divided into two types: global feature representation and local feature representation. The global feature representation method encodes the human body movement observation as a whole, which can be regarded as a top-down approach. This article uses the global feature representation method, extracting features in the action interest area to get a feature descriptor. So for an action video, you will get a sequence of feature descriptors.
For action matching, this article uses a sequence of action primitives to represent a human action. The action feature descriptors obtained by extracting features from the training video are clustered into k action primitives θ through K-Means, thereby obtaining a set of action primitives. So any action can be regarded as a sequence of action primitives θ. Then, the dynamic time warping algorithm (Dynamic Time Warping, DTW) is used to calculate the sequence distance, so as to compare the similarity between different actions. If the similarity between the detected action sequence and the target action sequence is less than the threshold, it is determined that the target action is detected.
