Claim 1:
2. The method of claim 1, wherein the navigation condition of the ship includes an obstacle in an inland water, a starting point and a target point of ship navigation; and the operation S1 comprises:
S11, generating the navigation environment where the ship navigates, wherein, the navigation environment is generated by setting the inland water as a two-dimensional (2D) space where the ship navigates and establishing a 2D coordinate system in the 2D space;
S12, setting coordinates corresponding to the obstacle in the 2D coordinate system based on a size of the obstacle, a number of obstacles and a position of the obstacle in the inland water; and determining coordinates of the starting point and coordinates of the target point of the ship navigation;
S13, dividing the inland water with a length X, and a width Y in the 2D coordinate system to generate g×r square areas with a side length of u, then:, u
  =
  
   
    X
    r
   
   =
   
    Y
    g
   
  
 

where, X indicates the length of the inland water in the 2D coordinate system; Y indicates the width of the inland water in the 2D coordinate system; u indicates the side length of the square area; r indicates a number of the square areas in a length direction of the inland water; g indicates a number of the square areas in a width direction of the inland water;
S14, determining an obstacle area and a navigable area, the obstacle area being an area with the obstacle, and the navigable area being an area without the obstacle;
determining the risk area and a safe area based on the navigable area; the risk area being an area affected by an airflow, and the safe area being a navigation free area without an effect of the airflow.
