Novel vehicle track extraction method and system

The invention discloses a novel vehicle track extraction method and system, and the method comprises the steps: building a vehicle information extraction model, carrying out the prediction according to the existing track of a vehicle, obtaining a predicted vehicle track, obtaining an actual motion track of the vehicle, and carrying out the matching of the actual motion track of the vehicle and the predicted motion track of the vehicle, and obtaining an optimal vehicle track. And performing noise reduction processing on the optimal vehicle track to obtain a final vehicle track, thereby realizing extraction of the vehicle track. According to the method, prediction is carried out according to the existing trajectory of the vehicle to obtain the predicted trajectory of the vehicle, then the actual motion trajectory of the vehicle and the predicted motion trajectory of the vehicle are matched to obtain the optimal vehicle trajectory, and noise reduction processing is carried out on the optimal vehicle trajectory,
