[0031] The embodiments of the present application will be described in detail below with specific reference to the drawings. Those skilled in the art can easily understand other advantages and effects of the present application from the content disclosed in the specification. The present application can also be implemented or applied in different specific embodiments, and the details in the specification can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0032] It is to be noted that the drawings provided in the following embodiments only schematically illustrate the basic concepts of the present application, and only the components related to the present application are shown in the drawings, rather than being drawn according to the number, shape and size of the components in actual implementation, and the type, number and proportion of each component in actual implementation can be arbitrarily changed, and the component layout type can also be more complex.

[0033] Referring to Figure 1 In an embodiment of the present application, the ship base modeling method of the present application comprises the following steps:

[0034] In step S11, a theoretical plane of an installation panel of a ship equipment and a projection contour line of the ship equipment on the theoretical plane of the installation panel are obtained.

[0035] In step S12, a base panel model is generated by combining the projection contour line with a direction of the base profile, and a base support profile model is generated to complete the base modeling.

[0036] It is to be noted that first, a distance interference check is performed based on the installation surface of the ship equipment to obtain an installation panel on which the ship equipment is attached, and then a theoretical plane of the installation panel is obtained, and a topology analysis is performed on the ship equipment, and a three-dimensional feature of the ship equipment is projected on the theoretical plane of the installation panel to obtain the projection contour line.

[0037] Further, as shown in Figure 2 The ship equipment 1 includes various ship equipment, such as a main engine in a main power device, a generator in an auxiliary power device, a boiler, different types of pumps, a water maker, and various automation equipment. The distance interference check is a commonly used technology in three-dimensional design, which checks whether there are three cases of contact / gap / intersection between each two of a plurality of three-dimensional models, wherein the contact means that the three-dimensional models just produce point / line / surface contact; the gap means that there is a distance between the three-dimensional models, and the distance is less than a specified value; and the intersection means that the three-dimensional models exist in the case of mutual entity and the other entity invasion overlap.

[0038] Specifically, for a device model in a three-dimensional modeling software, the device model is generally composed of point, line, surface and volume topology, and the corresponding device model topology surface can be taken out by corresponding program in the three-dimensional modeling software, and the projection contour surface of the device can be obtained by projecting on a theoretical plane, and then the projection contour line can be parsed from the projection contour surface by the corresponding program, so that the projection contour line can be obtained by performing topology analysis on the ship equipment and then performing projection.

[0039] Further, in an embodiment of the application, the obtaining the ship base profile orientation and combining the projection contour to generate a base platform model specifically comprises: obtaining base profile data and base platform data, wherein the base profile data comprises the ship base profile orientation, the number and / or interval of base support profiles, and the specifications and materials of the profiles, and the base platform data comprises the specifications and materials of the base platform; obtaining a filling surface based on the projection contour, topologically processing the filling surface to obtain a target rectangle, and generating the base platform model based on the target rectangle.

[0040] Specifically, when determining the ship base profile orientation, it is desirable that the profile arrangement matches the equipment model as much as possible, and therefore the geometric shape of the equipment model needs to be given; the base support profiles are, for example, angle steel, I-beam, elbow plate, channel steel, and square steel; the specifications and materials of the profiles are determined by obtaining given values from the user end.

[0041] Further, to establish the base platform model, a program in a three-dimensional modeling software can generate a filling surface with a closed contour line on a plane as an outer contour, the projection contour is taken as an input to obtain the filling surface, the filling surface is topologically processed, the ship base profile orientation is combined to obtain a rectangular shape containing the filling surface, and the shape is contracted in two directions until it is ensured that the rectangular shape covers the main area of the filling surface to obtain the target rectangle, and the base platform model is generated based on the target rectangle.

[0042] It is worth mentioning that, for the filling surface, a minimum envelope rectangle can be obtained in combination with the ship base profile orientation (e.g., taking the base orientation as the long side direction of the rectangle), and the rectangle is contracted in the u direction and the v direction until the rectangular shape substantially covers the main area of the filling surface. The main area can be defined and evaluated in different ways according to actual needs. For example, for a certain project in the shipbuilding industry, a direction such as the u direction can be randomly selected for contraction, and the contraction is stopped when the area change value reaches the ideal value. In this way, the area of objects such as pipes extending at the edge of the irregular model can be ignored as much as possible to obtain a rectangular theoretical surface similar to the main area.

[0043] It is worth mentioning that, based on the number and / or interval of the base support profiles, the theoretical starting point and ending point positions of each support profile are obtained to generate the base support profile model.

[0044] It should be noted that, as shown in FIG. 2, the intervals of the base 2 support profiles are generally the same, but sometimes the structural intervals can be different in order to align with the strong structures of the ship body. Figure 3 It should be noted that, as shown in FIG. 2, the intervals of the base 2 support profiles are generally the same, but sometimes the structural intervals can be different in order to align with the strong structures of the ship body.

[0045] Further, as shown in Figure 4 the method further comprises the following steps:

[0046] Step S41, acquiring a first contour line of a base support plate and a hull contact plate frame;

[0047] Step S42, identifying a second contour line of a ship structure on the hull contact plate frame;

[0048] Step S43, performing secondary modeling based on the first contour line and the second contour line.

[0049] It should be noted that the intersection of the first contour line and the second contour line is extracted, and the first contour line inside the second contour line is taken as a target contour line by taking each intersection point as an end point to complete the secondary modeling, as shown in Figure 5a and 5b In this embodiment, according to the contact between the base and the hull, the first contour line L1 is generated by projecting on the theoretical surface of the deck back of the hull; the hull contact plate frame, i.e., the hull equipment on the deck, is identified and the hull equipment contour line L2 is generated by projecting on the theoretical surface of the deck back; the projection line in L1 is extended outward to ensure that the end point of the line segment is on L2, if the line segment is intersected by L2, then L1 is truncated with L2 as the boundary to obtain the second contour line L1'; according to the second contour line L1' and the given value of the user end, the necessary parameters such as the specification and material of the hull structure that need to be strengthened are determined, and the base strengthening modeling is performed to complete the secondary modeling, wherein L1 is four intersecting solid lines in the shape of “#” and not connected with L2, L2 is four intersecting dotted lines in the shape of a rectangle, and L1' is four intersecting solid lines in the shape of “#” and connected with L2.
