The embodiment of the invention provides a vehicle track reconstruction method and device, and relates to the technical field of intelligent traffic. Comprising the steps of obtaining an initial vehicle track of a target vehicle, road network data of an area where the target vehicle is located and signal lamp state data; inputting the initial vehicle track, the road network data and the signal lamp state data into a target data driving reconstruction model to obtain a plurality of target track points corresponding to the initial vehicle track; determining a reconstructed vehicle track corresponding to the initial vehicle track based on the initial vehicle track and the plurality of target track points; the target data driving reconstruction model obtains a plurality of target trajectory points through the following steps: extracting vehicle motion features in an initial vehicle trajectory; carrying out data fusion on the signal lamp state data and the vehicle motion characteristics, and predicting a plurality of track points of the target vehicle based on the fused data; and constraining the plurality of track point coordinates based on the road network data to obtain a plurality of target track points conforming to the road network data.
