Title:
GESTURE RECOGNITION METHOD AND DEVICE, AND POSITIONING AND TRACKING METHOD AND DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/258106
Kind Code:
A1
Abstract:
A gesture recognition method and device. The method comprises: acquiring gesture information that is illuminated by a millimeter wave signal on a hand of a user and is collected by at least two radar sensors after being reflected by the hand (S110); deconstructing the hand according to the gesture information to obtain a plurality of discrete surface energy points (S120); and recognizing the gesture of the hand according to movement trends of the plurality of surface energy points (S130). The method can perform gesture recognition on the basis of a gesture deconstruction method and a neural network customized for the method, and can be widely used to recognize a large number of different gestures. Furthermore, provided are a positioning and tracking method and device which can avoid or correct environmental interference, obtain accurate and non-interfering positioning coordinates, and successfully complete real-time positioning and tracking.
