Whole sample traffic flow track generation method and system based on multi-vehicle environment perception

The invention discloses a full-sample traffic flow track generation method and system based on multi-vehicle environment perception, and the method comprises the steps: carrying out the track reconstruction of the full-sample traffic flow of a road network where a current vehicle is located based on a kinematic model according to the traffic flow information and the vehicle information of the current vehicle, and obtaining the preliminary full-sample traffic flow information, judging whether a signal-lost vehicle exists or not, and if yes, judging whether a data missing condition of the vehicle information corresponding to the signal-lost target vehicle is true or not; if the target vehicle is true, based on the vehicle information of all other vehicles in the road network where the current vehicle is located, the motion state of the target vehicle before signal loss and the motion states of surrounding vehicles are extracted, and based on the motion interaction prediction model after training is completed, t
