Abstract

The invention discloses a finger independent action recognition method and system based on an MMG signal, wherein the method comprises the following steps that an equipment side performs real-time collection on the MMG signal through a sensor; a low-power-consumption Bluetooth technology is used for transmitting the collected MMG signal to an intelligent terminal in real time; after the intelligent terminal receives the MMG signal, the MMG signal is sequentially subjected to denoising, signal section extraction, feature extraction and sequencing, mode recognition processing; the recognition result is obtained and output. Through the method and the system, the simultaneous real-time recognition on single finger action of five fingers on the basis of the MMG signal can be realized; the recognition rate is as high as 93.1 percent.

Description

technical field [0001] The invention relates to the technical field of biological signal recognition, in particular to a method and system for recognizing independent finger movements based on muscle movement signals. Background technique [0002] Mechanomyograph (MMG)-based hand motion recognition technology, as a new type of human-machine interface technology that can be applied to artificial limb control, virtual reality rehabilitation training and other fields, has been widely used in academia and industry in recent years. Pay attention and research, and there are tons of jobs popping up. However, most of the existing hand motion recognition technologies with similar principles are based on electromyography (EMG) or the combination of EMG and muscle signals to realize hand motion recognition, and only rely on MMG signals. The current state of research on hand motion recognition is still mainly focused on the recognition of some large hand motions, such as the recognitio...
