Embodiment Construction
[0028] like figure 1 A schematic flowchart of the method of the present invention: this multi-feature fusion-based method for human hand trajectory prediction and intention recognition provided by the present invention includes the following steps:
[0029] S1. Obtain the key point data of the face and shoulder of the person; obtain the palm trajectory data;
[0030] S2. Input the human face and shoulder key point data into the support vector machine (SVM) to obtain the face orientation modal information; input the palm trajectory data sequence into the Savitzky-Golay filter (SG filter) to eliminate the trajectory data fluctuate to obtain smooth trajectory data;
[0031] S3. Perform parallel fusion of the two modal information to obtain multi-modal fusion information;
[0032] S4. Input into the LSTM (Long Short-Term Memory) network, and output the predicted trajectory of the palm.
[0033] like figure 2 It is a schematic diagram of the position of key points in the metho...
