Target vehicle track prediction method for multi-lane scene

The invention discloses a target vehicle trajectory prediction method for a multi-lane scene, and the method comprises the steps: extracting historical trajectory features from the historical state information of a target vehicle and the historical state information of surrounding vehicles through a historical trajectory feature coding module, obtaining historical track characteristics of the target vehicle and historical track characteristics of surrounding vehicles; processing the historical trajectory features of the target vehicle and the historical trajectory features of the surrounding vehicles by using an interaction feature coding module to obtain interaction features of the target vehicle; utilizing a multimode decomposition bilinear pooling module to carry out feature fusion on the historical trajectory features and the interaction features of the target vehicle to obtain trajectory codes of the target vehicle; processing the track code of the target vehicle by using a multi-model identification mod
