Claim 4:
5. The polar navigation window period assessment system based on three-dimensional visualization simulation of ship-ice interaction according to claim 4, wherein the route layer is used for establishing a navigation route bathymetric distribution map according to a latitude and longitude range of Arctic Northeast route; the sea ice layer is used for simulating environmental changes of waves, sea ice, wind fields and dense fog according to the changes in time and space; the wave layer is used for simulating fluctuating effects by combining wave heights and wave periods; the wind field layer is used for making flags on ships flutter with wind by indicating information of wind speeds and wind directions; and the dense fog layer is used for increasing dense fog and obtaining an effective sight distance of personnel on the ship through visibility indexes.
