The invention discloses a ship collision accident inversion scene construction method, which comprises the steps of obtaining VDR data of a ship collision accident, analyzing the VDR data, and constructing a collision accident inversion data set based on the analyzed data; constructing matrix position data, registering the grid nautical chart of the ship collision accident occurrence area with the matrix position data to obtain a grid nautical chart geographic information graph matrix model, and constructing an accident inversion scene based on the grid nautical chart geographic information graph matrix model; wherein the registration process comprises the step of carrying out data fusion on a collision accident inversion data set and a grid nautical chart. According to the method, on the basis of researching a VDR data analysis method, a sea chart information extraction model is established by combining the characteristics that grid sea chart data is convenient for spatial analysis and relatively high in current trend, and grid sea chart geographic information extraction, registration and multi-source navigation data fusion are carried out, so that construction of an inversion scene of a ship collision accident scene is realized.
