The invention discloses an electromyographic
signal and gesture intention mapping model, and belongs to the field of
artificial intelligence and
biological signal processing. According to the method, for double-arm sign
language recognition, synchronous electromyographic signals of a left
forearm and a right
forearm when a user executes a preset sign language gesture are collected, and a training
data set is constructed; a double-flow fusion neural
network model based on an attention mechanism is constructed to serve as a mapping model, an
encoder part of the double-flow fusion neural
network model comprises two long and short-
term memory network branches for
processing left and right arm signals respectively, and a decoder part of the double-flow fusion neural
network model comprises a fusion attention layer used for dynamically calculating and fusing weights of double-arm features to generate a joint
context vector. And finally mapping to a gesture intention category. The model effectively captures the space-time cooperation relation of the
muscle activities of the two arms in the gestures of the two hands, and high-precision and robust mapping from original electromyographic signals to complex gesture intentions is achieved. The invention also protects the training method of the model and the application of the model in a sign
language recognition system.
