Embodiment Construction
[0039] In specific implementation, figure 1 It is a human behavior recognition method flow based on convolutional neural network.
[0040] This example uses the MSRAction3D dataset, which is captured by the Microsoft Kinect v1 depth camera and contains 20 actions.
[0041] First, the system sequentially acquires the human skeleton sequences in the dataset. In the received joint pose sequence, given specific N frames [F 1 , F 2 ,...,F N ] of the human skeleton sequence s, let (x i ,y i ,z i ) is the nth frame {F n} ∈ 3D coordinates of each human joint in s, where n ∈ [1,N].
[0042] Next, the joint pose sequence transforms the 3D coordinates of each human joint in s into the 3D joint coordinates in the normalized space s′ (x′ i ,y′ i ,z' i ), stack the coordinates of all normalized spaces to form a time series [F′ 1 ,F' 2 ,…,F′ n ] to represent the entire action sequence, quantizing these elements into the RGB color space. In the order of two arms, one torso, and...
