The invention provides a trajectory prediction method based on space-time interaction feature fusion. The trajectory prediction method comprises the following steps: collecting traffic participant information on a road in real time; constructing a traffic scene expression model based on the traffic participant information; constructing a multi-scale space-time diagram convolution model to enable the multi-scale space-time diagram convolution model to extract space-time interaction features of the traffic participants based on the traffic scene expression model; and constructing a trajectory prediction model to enable the trajectory prediction model to perform trajectory prediction based on the space-time interaction characteristics, and obtaining a prediction trajectory. According to the trajectory prediction method based on space-time interaction feature fusion provided by the invention, the traffic scene expression is constructed and the space-time interaction features of the traffic participants are extracted, so that the finally obtained vehicle prediction trajectory can capture the spatial correlation of the behaviors of the traffic participants on different time scales; and multi-scale space-time fusion interaction features are extracted, so that the precision of trajectory prediction can be effectively improved.
