The invention discloses a path reconstruction method and device, computer equipment, a storage medium and a product, and the method comprises the steps: obtaining a sampling traffic path in a to-be-reconstructed region, and enabling the sampling traffic path to comprise a starting point traffic region and a terminal point traffic region; performing path clustering processing on the sampled traffic paths based on the starting point traffic area and the terminal point traffic area to obtain a target traffic path; obtaining a checkpoint traffic flow obtained by carrying out flow detection on a target road section in the to-be-reconstructed region; based on the target traffic path, carrying out maximum entropy flow distribution on the checkpoint traffic flow to obtain the path flow of the target traffic path relative to the target road section; and performing path reconstruction on the to-be-reconstructed region based on the target traffic path and the path flow to obtain path distribution and path flow in the to-be-reconstructed region. According to the invention, path reconstruction is carried out based on the sampled target traffic path and the total traffic flow detected by the checkpoint, so that the path reconstruction result accords with the real traffic flow condition, and the path reconstruction result is more accurate.
