Abstract
The present invention discloses a pedestrian trajectory prediction method and system based on a multi-interaction spatio-temporal graph network, which belong to the field of pedestrian trajectory prediction. The method includes: extracting multi-interaction features of pedestrians in video frames; for each frame in a video sequence, abstracting each pedestrian in the frame as a vertex, connecting the pedestrian(s) with other pedestrians to form an edge(s), where the vertex attribute is the multi-interaction feature of the pedestrian so as to obtain a multi-interaction spatio-temporal graph network; for each multi-interaction spatio-temporal graph, obtaining spatial dependencies of each pedestrian with other pedestrians in the spatio-temporal graph, and optimizing the attribute of each vertex through the spatial dependencies between pedestrians; the vertices of adjacent time points of the pedestrians are connected to obtain time dependencies of the pedestrians, and then infer a trajectory of a future time point(s).
