The invention discloses a
pedestrian trajectory prediction method based on GCN
interactive modeling, and the method comprises the steps: defining each
pedestrian as a node, and building a
pedestrian space diagram according to the relative position of the pedestrian, so as to capture the space relation between the pedestrians; in the pedestrian space diagram, speed information is added for pedestrians, and a speed
adjacency matrix is constructed; in the pedestrian space diagram, the categories of objects around pedestrians are used as labels to be embedded, and a
label adjacent matrix is constructed; combining the speed
adjacency matrix with the
label adjacency matrix to generate a semantically guided adjacency graph; inputting the adjacent graph into a space-time graph
convolution network, carrying out space-time
convolution operation on the graph representation of the pedestrian trajectory, and respectively extracting a time feature and a space feature; and inputting the obtained features into an improved time extrapolation
pyramid convolutional neural network, and jointly estimating two-dimensional
Gaussian distribution parameters of a future trajectory through multi-layer prediction features so as to obtain a pedestrian trajectory. According to the method, the influence degrees of different objects are considered, different
label classifications are designed for different objects, and the social attributes are fully utilized to calculate the weight of social interaction, so that a better pedestrian prediction result is realized.
