ULTRASONIC WAVE-BASED AIR GESTURE RECOGNITION METHOD AND SYSTEM

WIPO Patent Application WO/2017/152531

A1

An ultrasonic wave-based air gesture recognition method and system. The method comprises: using a pre-trained palm movement trend model to recognize palm movement trends on the basis of collected ultrasonic wave signals reflected back by a human hand to obtain a palm movement trend timing sequence comprising a series of palm movement trends, wherein the palm movement trend model is a model obtained by training according to acoustic characteristics of the ultrasonic wave signals reflected back by the human hand and used for recognizing the palm movement trends; and performing gesture recognition on the obtained palm movement trend timing sequence by using a pre-trained gesture recognition model, wherein the gesture recognition model is a model obtained by training according to a training data set consisting of the palm movement trend timing sequence and used for recognizing a gesture. The method and system are applicable to a smart mobile terminal, and can achieve both high precision and high robustness of gesture recognition.
