A system and method for generating terrain data.

Recently, ICT technology has been actively used at home and abroad, and in particular, many construction automation construction based on MC equipment equipped with GPS has been attempted. However, in order to utilize MC (Machine Control) equipment in the underground space and foundation trenching of building structures, 3D terrain data is required. However, it is currently difficult to secure 3D design data, which is a obstacle to generalization of construction automation construction based on MC equipment.

The main reason is that the drawings supplied by the civil engineering or architectural designer to the client are submitted on a 2D basis. In addition, even if drawings were created by 3D design, it is difficult to clearly reflect the site situation during design, so it is necessary to rewrite or change the design at the construction stage. Currently, in this case, the 3D drawings necessary for operating the MC equipment are created and actual by manually reworking the drawings by using the 2D drawings supplied by the drawing workers. It takes a lot of time to perform the work by hand, and human error can occur. Therefore, in order to expand the use of MC in the future, measures for it are urgently needed.

1 is a schematic block diagram of a three-dimensional terrain data generation system for long haul and foundation digging of a building structure according to an embodiment of the present invention. In FIG. 1, the 3D terrain data generation system 100 for long and long ground breaking of a building structure includes a design information acquisition unit 110, a virtual space generation unit 120, an internal solid formation unit 130, and a solid agent. It includes a rejection 140, and a three-dimensional terrain extraction unit 150, and the boundary slope and small end forming unit 160, the three-dimensional terrain extraction unit 150 again individual object conversion unit 152 and the object removal unit 154.

In FIG. 1, each component of the 3D terrain data generation system 100 for cadastral and basic excavation of an architectural structure may be implemented only with hardware, but it may be common to implement together with hardware and software operating on hardware.

The design information acquiring unit 110 obtains planar shape information and height information of the internal figures located in the entire building foundation trench area and inside the building foundation trench area from the two-dimensional design information. Fig. 2 is a plan view of the start of transformation of the foundation foundation. In the plan view of FIG. 2, it is possible to check the overall shape of the building foundation trench area and the planar shapes of the internal shapes located inside the area.

The virtual space generation unit 120 uses the obtained planar shape information and height information to generate a 3D virtual space that may include the entire construction foundation trench area. Since the virtual space only needs to include the entire trenching region therein, there is no limitation on the shape, but it will generally be a cuboid shape. The virtual space may be automatically generated by the input design information, or may be generated by inputting a location or size input by a user.

The inner solid forming unit 130 forms an inner solid, which is a three-dimensional space, by using plane shape information and height information of the inner shapes in the virtual space. At this time, the inner solid may have a larger area than the lower area.

3 to 7 are diagrams showing the basic concept of forming an internal solid. FIG. 3 shows an example in which the internal shape has a rectangular planar shape. In FIG. 3, the inner solid has a height of -4 and a bottom of -7, so it can be seen that the top of the inner solid is formed in a virtual space having a top of 10 and a bottom of -10.

In addition, it can be seen that the area of the lower portion of the inner solid is formed narrower than the area of the upper portion, and the narrowness of the area can be adjusted using a preset value or slope by a user or the like.

FIG. 4 shows an example in which the planar shape of the internal figure is an unformed polygon, and in particular, FIG. 5 shows an example in which the heights of the lower ends are different. In addition, FIGS. 6 and 7 illustrate examples in which internal shapes of various shapes shown in FIGS. 3 to 5 are located together in a virtual space.

The solid forming unit 130 may further form an upper solid extending from the upper portion of the inner solid to the upper portion of the virtual space, and the formed inner solid and the upper solid may be combined into one combining solid. According to such a configuration, it is possible to form a 3D topography of an architectural foundation trench region in a simple and effective virtual space.

8 is a diagram illustrating an example in which an inner solid and an upper solid are combined. For example, you can combine the inner solid and the upper solid by using the Booleab Union function of the CAD program.

The solid removal unit 140 removes the internal solid from the generated virtual space. At this time, the removal of the solid may be performed first from the solid having the lowest height. According to this configuration, unnecessary lines at various levels of the generated 3D drawing can be removed. 9 is a diagram illustrating logic to remove solids in order, and FIG. 10 is an example of an output screen in which results sorted according to lower heights are illustrated.

The individual object converting unit 152 decomposes components forming the virtual space from which the combined solid is removed and converts them into individual objects, and the object removing unit 154 has some or more of the individual objects within a preset range from the top of the virtual space. Remove included objects. According to such a configuration, it is possible to extract only the 3D terrain portion by removing unnecessary lines from the 3D drawing including the virtual space.

FIG. 11 is a diagram illustrating logic for removing unnecessary lines from the 3D terrain extraction unit, FIG. 12 is a diagram illustrating a range formed to select an object to be removed from the top of virtual space, and FIG. 13 is executing unnecessary line removal The extracted 3D terrain is then shown.

FIG. 14 is a schematic flowchart for performing a method for generating 3D terrain data for geological longing and foundation breaking of an architectural structure according to an embodiment of the present invention, and FIG. 15 shows a specific process according to FIG. 14. It is an output screen, and FIGS. 16 and 17 are plan and perspective views, respectively, of a completed 3D drawing.

14 and 15 are provided in the form of a 3 ^rd Party Add-in Program based on the AUTODESK AUTOCAD program, and can be implemented to be easily utilized by anyone with a general purpose CAD user. The generated 3D terrain data may be provided in various forms, and as illustrated in FIG. 15, may be provided in the form of a 3D wire frame.

As a more specific example, the destruction of the architectural foundation structure utilizes the subtract Boolean of the solid (Solid) and the solid using the polygonal top/bottom level property and the slope value in the large solid in the virtual space. Three-dimensional faces can be created by sequentially removing shapes.

The building foundation digging module can collectively generate the entire building foundation digging 3D shape by inputting the bottom height and the top height and ratio or distance values of a quadrangular or multi-polyline shape.

The basic structure of the building is the shape of the inverted pyramid shape, and has the lower height and upper height values of the trench, and if they are close to each other, it is necessary to process the overlapping shapes. The logic for processing this can be completed by subtracting from the base of the low level in the virtual rectangular solid in order to complete the size of the site, the basic shape, and the overlapping shape with two or more different levels.

The boundary slope and the small section forming unit 160 generates 3D terrain data of the slope and the small boundary of the site in the building foundation trench area from the 2D design information. According to such a configuration, it is possible to easily generate three-dimensional topography data for slope construction, even for boundary slopes or retaining wall structures that need to be installed when constructing a large-scale business site such as a residential complex or an industrial complex.

That is, it is possible to generate 3D data by acquiring the shape information and height information of the slope/small plate from the 2D design information, and to utilize this data when applying ICT technology in the field.

FIG. 18 is a view showing a workflow of processing a slope and an end of a site boundary, FIG. 19 is a view showing a process in which user input is performed through a polyline in FIG. 18, and FIG. 20 is a logic execution screen of FIG. 18, 21 to 23 are views illustrating the results of the slope and cut processing of the site boundary by the process of FIG. 18.
