Problems solved by technology

[0003] At present, gesture interaction is the most direct operation method in human-computer interaction. In the existing gesture interaction, only the operator's hand movements are recognized, and the gestures of the operator's entire arm (including the forearm, upper arm and hand) cannot be recognized. However, it is also possible to cause hand movements during the movement of the forearm and upper arm. Therefore, in the process of gesture recognition, it is necessary to eliminate the influence of relative movement in order to obtain the correct gesture of the operator.
At the same time, the existing gesture interaction cannot properly fuse the operator's EEG signal and the operator's EMG signal, resulting in the inability to correctly capture the operator's correct action intention, which in turn leads to wrong actions on the controlled unmanned platform Unmanned platforms are in danger

Description

technical field [0001] The present invention relates to the technical field of human interaction, in particular to an unmanned platform control system and control method that integrates myoelectricity and electroencephalogram information. Background technique [0002] Myoelectric signal is a kind of bioelectric signal generated by neuromuscular activity, which contains a lot of information related to limb movement, and is the comprehensive result of muscle bioelectric activity on the skin surface in time and space. The EEG signal is a very weak non-stationary signal, which contains a large number of electrophysiological activity information of brain nerve cells, and reflects people's thinking activities and body movements. According to the characteristics of myoelectric signal and EEG signal, the combination of the two is applied to the field of human-computer interaction. As a kind of human behavior, gestures are convenient, fast, rich in meaning, and easy to understand. I...
