FIG. 6 is a view for explaining a data interpolation technique of a three-dimensional depth-by-depth temperature distribution model of the three-dimensional spatial information synthesis module of FIG. 3, and FIG. FIG. 8 is a view for explaining the results of the three-dimensional spatial information on the three-dimensional space, FIG. 8 is a view for explaining the data of the temperature distribution model according to the water depth in FIG. FIG.

6 to 8, the three-dimensional depth-based temperature distribution model generates a three-dimensional spatial grid structure (X, Y, Z) from the sea floor to the sea floor of the designated area on the basis of the user requirement data, To generate a temperature distribution map for each water depth including the marine environment information such as water temperature and sound velocity for each water depth.

At this time, since the basic environment data can not have the measurement values for all the spaces in the designated area in the information generation module 320, the surrounding values are linearly combined between vertically adjacent water temperature distribution maps, And interpolation is performed. The three-dimensional spatial information synthesis module 340 is a data value that is spatially correlated with the temperature distribution by depth.

In this case, when measuring marine information such as water temperature and sound velocity in an actual marine environment, the measurement values of marine information for a plurality of points are used in units of predetermined distance, so that the three- In estimating the data value of the temperature distribution, the measured values measured at the actual measurement point and the plurality of measured values measured at the plurality of points located within the set radius based on the actual measurement point are used. That is, the three-dimensional spatial information synthesis module 340 applies a linear interpolation method, a kriging interpolation method, or a thin plate splines (TPS) interpolation method so as to reflect not only the distance from the measured value but also the correlation strength between the measured values do.

Here, the Kriging interpolation method requires a large amount of calculations since a new weight is calculated every time the interpolation is performed at a new point. In order to overcome such disadvantages, the user requests the marine environment model of the information generation module 320 to set a detailed unit zone for the entire designated zone, perform preliminary interpolation for each zone, and store the zone in the memory on the system. In addition, Kriging interpolation can update the memory area value for the adjacent subspace after the real-time data interpolation for the measurement point when the measurement value for the new marine environment is generated or applied centered on the user's position, .

In addition, the temperature distribution model for three-dimensional water depths is obtained by interpolating thin plate splines (TPS) after applying kriging interpolation between vertically adjacent water depth distributions and correcting the aliasing of data that can occur in the lattice structure, By gently connecting the data on the spatial structure, the data values can be arranged to resemble the actual temperature distribution phenomenon.

In an environment where it is difficult to collect or measure actual measurement data depending on weather conditions or operating environment, interpolation method is applied by applying annual average statistical information on designated areas accumulated in the environmental information database (371) do.

As shown in Fig. 7, the data arranged through the interpolation is numerically present in all areas of the designated area space. When the three-dimensional space area is represented by computer graphics, the control terminal 200 simultaneously displays all the calculated spatial values, but it can not confirm only the information or form of the outermost surface in which data is displayed at the user's viewpoint. This phenomenon is the same as when the three-dimensional object is seen, the visible part is confined to the outer surface and the inner state is not visible. A representative example of a method of expressing the state of a gas or a fluid by a computer graphic method is to express the internal data or state by setting the transparency or changing the intensity of the color. However, Dimensional computer graphics, there is a limitation that the internal information can not be expressed in a macroscopic viewpoint because the attribute or information to be expressed in the case of the high-density object is complicated due to the organic relation.

In order to overcome this shortcoming and clearly express the density state of the water temperature distribution in the water in three dimensions, as shown in Fig. 8, a three-dimensional (X, y, z), and the basic environment data including the marine environment information such as water temperature and sound velocity of the water depths refined by the interpolation to the three-dimensional coordinate information of the grid structure is stored in a point or an adjacent coordinate And maps in the form of a sphere or a cube having a minimum diameter that can not exceed the area. In this case, the spacing of the grid structure can be adjusted by the user's operation or the set value on the system, and it is possible to select the LOS (Line of Sight) interval that is easy to identify from the user's point of view and set this interval as the basic interval.

At this time, the representation method of points, spheres and cubes mapped to the three-dimensional space coordinates can set the legend and category according to the range of the interpolated basic environment data of the designated area requested by the user and the setting of the user, flickering, transparency, and the like, so that the status information can be intuitively confirmed.
