The invention provides a trajectory prediction method, device and equipment. The method comprises the following steps: inputting an obtained first target feature of a target moving object to a trained intention simulator to obtain first prediction data of K future moments; determining a target position of the future moment based on the Gaussian parameter of the candidate position corresponding to the future moment, and determining a second target feature of the target moving object based on the target positions of the K future moments; inputting the second target feature into a trained trajectory predictor to obtain second prediction data of K future moments; and determining a target mode of the future moment based on the prediction probability of each mode corresponding to the future moment, determining a prediction position of the future moment based on the Gaussian parameter of the candidate position corresponding to the future moment, and determining a prediction trajectory of the target moving object based on the target modes and the prediction positions of the K future moments. According to the technical scheme, the accurate and reliable prediction trajectory can be obtained, and the quality of the prediction trajectory can be improved.
