Embodiment 1

[0044] Example 1, such as figure 1 As shown, an EEG-EMG signal fusion device according to the first embodiment of the present invention includes an EEG acquisition helmet, an EMG acquisition device and an embedded computer. The EEG acquisition helmet is used to collect the operator's EEG signal, and capture the operator's brain thinking intention according to the EEG signal; the EEG acquisition helmet collects the video signal in the operator's visual area, and performs identification and mapping according to the video signal; The electric collection helmet collects the temperature signal of the operator's head, and senses the temperature of the operator's head during exercise according to the temperature signal to cool down the operator's head. The myoelectric acquisition device is used to collect the myoelectric signal of the operator's gesture commanding action, and recognize the operator's commanding action according to the myoelectric signal. The embedded computer is con...

Embodiment 2

[0060] Embodiment 2, a kind of EEG-EMG signal fusion method described in the second embodiment of the present invention, the method comprises:

[0061] Step 1, the camera in the visual perception AR augmented reality information display module set on the EEG collection helmet collects video data in the operator's field of view, and transmits the video data to the EEG processing module;

[0062] Step 2, the video data is transmitted to the third FPGA processor set in the embedded computer through the first wireless transmission module in the EEG processing module to identify the video data, and map the video on the visual perception AR augmented reality information display module in the lens display within;

[0063] Step 3, start a number of EEG electrodes evenly arranged on the EEG collection helmet, these EEG electrodes receive the EEG signals of the operator, and the EEG acquisition module set on the EEG collection helmet collects the EEG signals of the operator, and the EEG s...

Abstract

The invention discloses an electroencephalogram and electromyography signal fusion device. The electroencephalogram and electromyography signal fusion device comprises an electroencephalogram signal acquiring helmet for acquiring an electroencephalogram signal, capturing a brain thinking intention, acquiring a video signal in a view zone, identifying mapping, acquiring a head temperature signal and cooling the head, an electromyography signal acquiring device for acquiring an electromyography signal of a gesture pointing and controlling action and identifying the pointing and controlling action according to the electromyography signal, an embedded computer in signal connection with the electroencephalogram signal acquiring helmet and the electromyography signal acquiring device, receiving the electroencephalogram signal and the electromyography signal, performing fusion processing, detecting the intension of the pointing and controlling action of an operator, determining the correct pointing and controlling action of the operator and displaying the contents of the pointing and controlling action of the operator. The invention further discloses an electroencephalogram and electromyography signal fusion method. The electroencephalogram and electromyography signal fusion device and method has the advantages that the brain thinking intention can be rapidly captured, the gesture pointing and controlling action can be identified, false triggering caused by unintentional actions or passive actions is eliminated, and the reliability of man-machine natural interactive control is improved.

Description

technical field [0001] The present invention relates to the technical field of human interaction, in particular to an EEG-EMG signal fusion device and fusion method. 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. At present, gesture interaction is the most direct operation method in human-computer interaction, but the current gesture interaction cannot correctly capture the brain's int...
