Embodiment Construction
[0021] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings: this embodiment is implemented on the premise of the technical solution of the present invention, and provides detailed implementation plans and specific operating procedures.
[0022] Such as figure 1 , the method of the present invention mainly includes three steps: (1) the multi-stream data fusion method processes the original data; (2) replaces the fully connected calculation in the SRU gate structure with the graph convolution calculation, and constructs a graph convolution simple loop network (GC -SRU); (3) Introduce the spatial attention mechanism in the GC-SRU network, and finally get the result of action classification.
[0023] Each step will be described in detail below one by one.
[0024] step one:
[0025] The present invention uses 4 modes of data streams, which are node streams with original joint point coordinates as input, bone st...
