The invention discloses a bionic hand gesture locking method, device, terminal and storage medium. The method includes: acquiring a first myoelectric signal, determining a first gesture corresponding to the first myoelectric signal; acquiring a second myoelectric signal, determining The second gesture corresponding to the second myoelectric signal, wherein both the first myoelectric signal and the second myoelectric signal are generated based on the brain movement intention of the wearer of the bionic hand, and the second myoelectric signal is the bionic hand performing the first gesture The myoelectric signal collected later; judge whether the first gesture is a lock gesture, and when the first gesture is a lock gesture, control the bionic hand to continue to perform the second gesture until the preset duration is reached. It solves the problem in the prior art that the wearer of the bionic hand is inattentive, which leads to fluctuations in myoelectric signals, which in turn leads to errors in gestures with a long operation time.
Description
technical field [0001] The present invention relates to the field of signal processing, in particular to a bionic hand gesture locking method, device, terminal and storage medium. Background technique [0002] Surface EMG is a complex result of the electrical activity of the subcutaneous muscles at the surface of the skin, which can be collected by surface electrodes. Because the bionic hand controlled by myoelectricity is direct and natural, the bionic hand controlled by surface myoelectricity has become a category with a large number of external power bionic hands. However, since the EMG signal is generated based on the wearer's brain activity, once the wearer loses focus, the EMG signal is prone to fluctuations, which in turn leads to errors in some gestures that take a long time to operate. For example, when the wearer controls the bionic hand to grab objects through myoelectric signals, if the wearer is not focused, it is easy to cause fluctuations in the myoelectric s...
