DEVICE AND METHOD FOR ARCHITECTURAL DESIGN COOPERATION

The present invention relates to an apparatus and method for architectural design collaboration. More specifically, the present invention provides a BIM virtual reality image that allows a site contractor to check a construction site in 3D virtual reality and a rendering virtual reality image that enables a client to check the material or texture of interior elements close to the real thing It relates to an apparatus and method for

The market for architectural design and interior design is continuously growing, and in recent years, productivity and profitability are improving in the fields of design, construction, and maintenance by fusion with the 4th industrial revolution technology. In particular, the 4th industrial revolution technologies such as virtual reality are being applied in various ways in the field of interior architecture, such as interior decorating the interior of a building through furniture or props.

However, despite the use of technologies such as virtual reality, customer satisfaction in the building/construction industry remains low compared to other industries. This can be attributed to the fact that the communication process between the client, the design company, and the on-site construction company is inefficient due to the nature of the building/construction industry.

Productivity may deteriorate due to frequent design changes due to customer change of mind between the client and the design company. In addition, as described above, services such as interior change simulation using virtual reality are provided, but the texture of furniture, props, or wallpaper provided by the simulation is often different from the actual construction result. However, there may be limitations in improving customer satisfaction by virtual reality services.

In addition, the inaccuracy of information transmission can be a problem between the design company and the on-site construction company. Design companies produce design drawings in the form of 2D and deliver them to on-site contractors, but as the details of interior architecture become increasingly complex, accurate construction based only on 2D drawings depends to a large extent on the experience of the company. Therefore, there may be differences in the construction skill level of each company.

In addition, even when 3D drawings are used, their effectiveness is reduced due to low resolution, and when software dedicated to architectural design is used, it is difficult to access at the site, so accurate communication may be limited. Problems can arise.

Therefore, in order to solve the problem of customer change of mind or difference from the real thing that occurs between the client and the design company, and the problem that the accuracy of information transmission between the design company and the on-site construction company is low, we support collaboration in architectural design. Therefore, technology to improve communication efficiency may be required.

The technical problem to be solved by the present invention is to solve the problem of customer change of mind or difference from the real thing that occurs between the client and the design company, and the problem that the accuracy of information transfer that occurs between the design company and the on-site construction company is low To improve communication in the field of architectural design.

In a method for architectural design collaboration performed by a processor executing instructions stored in a memory according to another aspect of the present invention, 3D mapping is performed on a 2D design drawing for an architectural design object so that the design objects of the 2D design drawing are generating 3D structural drawings arranged in 3D space; generating a BIM virtual reality drawing by adding BIM (Building Information Modeling) objects to the 3D structural drawing; generating a rendered virtual reality drawing in which materials and textures of the design objects are expressed by performing HD rendering on the 3D structural drawing; and providing a BIM virtual reality image and a rendered virtual reality image that respectively output observation images for the BIM virtual reality drawing and the rendered virtual reality drawing based on the observation point in the 3D space that is changed according to a user input. include

According to the apparatus and method for architectural design collaboration according to the present invention, a 3D structural drawing corresponding to a 2D design drawing can be generated, and a BIM virtual reality drawing and a rendering virtual reality drawing can be generated again therefrom, so that each It is provided to construction companies and clients in the form of a 3D virtual reality space, and more intuitive and realistic information can be provided.

Specifically, the on-site construction company can check the structure in which BIM objects such as power distribution and plumbing equipment are arranged through the BIM virtual reality image at the construction site. can be accurately identified. In addition, since the requesting customer can more realistically check the material or texture of the indoor architectural structure through the rendering virtual reality drawing, the customer's change of mind due to lack of information can be reduced, and the problem of the difference between the customer's expectation and the real thing can also be solved. can

However, the present invention is not limited thereto, and other general-purpose components other than the components shown in FIG. 2 may be further included in the device 200 .

Apparatus 200 may be a computing device for implementing system 10 for architectural design collaboration. Device 200 may run a mobile/web application or computer program implementing system 10 . As described above in FIG. 1 , the apparatus 200 may be any one of a PC, a smart phone, and a tablet PC, but is not limited thereto, and the apparatus 200 may take the form of various electronic devices having processing capabilities. have.

The device 200 may include a memory 210 as a means for storing various data, instructions, at least one program or software, and performs processing on various data by executing the instructions or at least one program. The processor 220 may be included as a means for doing so.

For example, the memory 210 may store instructions constituting software such as a computer program or mobile/web application. In addition, the memory 210 may store various data required for execution of an application or program.

The memory 210 may be implemented as a non-volatile memory such as ROM, PROM, EPROM, EEPROM, flash memory, PRAM, MRAM, RRAM, FRAM, or the like, or a volatile memory such as DRAM, SRAM, SDRAM, PRAM, RRAM, FeRAM, etc. can be implemented as In addition, the memory 210 may be implemented as HDD, SSD, SD, Micro-SD, or the like.

The processor 220 may operate the system 10 by executing instructions stored in the memory 210 . The processor 220 may perform a series of processing processes for implementing the system 10 . In addition, the processor 220 may perform overall functions for controlling the apparatus 200 , and may process various operations inside the apparatus 200 .

The processor 220 may be implemented as an array of multiple logic gates or a general-purpose microprocessor. The processor 220 may be configured as a single processor or a plurality of processors. The processor 220 may be integrally configured with the memory 210 , rather than as a separate configuration from the memory 210 for storing instructions. For example, the processor 220 may be implemented in the form of at least one of a CPU, a GPU, and an AP provided in the device 200 .

The processor 220 executes instructions stored in the memory 210 to perform 3D mapping on a 2D design drawing for an architectural design object to generate a 3D structural drawing in which design objects of the 2D design drawing are arranged in 3D space. can be configured.

The 2D design drawing may refer to a two-dimensional architectural design drawing produced by the design company 12 . For example, the 2D design drawing is a CAD drawing of an indoor architectural space that is an architectural design target, and may be an electronic file created with a DWG or DXF extension. The 2D design drawing may include various design objects disposed on an architectural design target.

The design objects may include a floor object, a ceiling object, a wall object, a door object, a window object, a furniture object, and a prop object. Design objects may be expressed in two dimensions on a 2D design drawing. A structure in which an architectural design object will be built may be designed by various combinations in which design objects and characteristic data such as dimensions, colors, and materials of design objects are arranged.

3D mapping may refer to a process of arranging design objects of a 2D design drawing in 3D space. According to 3D mapping, design objects are arranged in a 3D space according to a design in a 2D design drawing, and a 3D structural drawing may be generated. The 3D structure drawing may refer to a drawing showing only the 3D structure designed in the 2D design drawing by reflecting only the size and shape of the design object without reflecting the color or material of the design object.

The processor 220 may be configured to generate a BIM virtual reality drawing by adding Building Information Modeling (BIM) objects to the 3D structural drawing by executing instructions stored in the memory 210 .

The building information model (BIM) may refer to a model for integrally managing the shape, properties, design, construction, and maintenance of a building facility based on a three-dimensional building model. BIM objects constituting BIM differ from simply design objects such as floors, ceilings, walls, doors, and windows in indoor architectural design, they mean objects related to working design for constructing various facilities in an architectural design target. can

The BIM objects may include a distribution equipment object, a plumbing equipment object, a firefighting equipment object, and a disaster prevention equipment object. When such BIM objects are added to the 3D structural drawing, the design, construction, and maintenance of the interior architecture may be integratedly managed by the building information model (BIM).

Both the 3D structural drawing and the BIM virtual reality drawing in which BIM objects are added to the 3D structural drawing may be electronic files created with an OBJ extension. When the 2D design drawing is a DXF file, 3D mapping to the 3D structure drawing can be easily performed due to the high compatibility of the DXF file, and then, when BIM objects are added to the OBJ file of the 3D structure drawing, the OBJ of the BIM virtual reality drawing A file may be created.

The processor 220 may perform HD rendering on the 3D structural drawing by executing instructions stored in the memory 210 to generate a rendered virtual reality drawing in which materials and textures of design objects are expressed.

HD rendering performed on a 3D structural drawing may refer to a process of converting 3D data described in numerical values and equations into human-recognizable images. When HD rendering is performed, details such as color, material, and texture of design objects constituting 3D structural drawings, such as wall objects, floor objects, and ceiling objects, are displayed in high resolution through the rendering virtual reality drawing. It can be expressed more realistically.

HD rendering can be performed smoothly even on low-end PCs or mobile devices despite the high-resolution image quality through an optimization algorithm. Accordingly, in the system 10 , the customer 13 may generate a rendered virtual reality drawing through his or her mobile device, and then check the details of the design objects in the virtual reality image.

The processor 220 outputs observation images for the BIM virtual reality drawing and the rendering virtual reality drawing based on the observation point in the 3D space that is changed according to the user input by executing the instructions stored in the memory 210, respectively. A BIM virtual reality image and a rendered virtual reality image may be provided.

The processor 220 provides the virtual reality to the user of the system 10, ie, the on-site construction company 11, the design company 12, and the client 13, based on the BIM virtual reality drawing and the rendering virtual reality drawing generated in the previous step. Real images can be provided. In the virtual reality, an observation image that changes according to a user's input, for example, a change of an observation position for changing an observation point of view or a change of an observation direction may be provided.

The BIM virtual reality image may be mainly provided to the on-site construction company 11 and the design company 12 . The on-site worker of the on-site construction company 11 may access the system 10 through his or her mobile device at the construction site to generate a BIM virtual reality drawing, and the on-site operator may observe on the BIM virtual reality drawing by their manipulation. By changing the viewpoint, you can check the 3D virtual reality image of the part you need to construct.

Therefore, the on-site construction company 11 can confirm the specific shape of constructing the facilities in 3D through the BIM virtual reality image, compared to the method of grasping the construction site only with the 2D design drawing, so the design company 12 can provide the 2D design drawing The construction intention planned while manufacturing can be delivered to the on-site construction company 11 more directly and accurately.

The rendered virtual reality image may be mainly provided to the design company 12 and the client 13 . The requesting customer 13 may utilize the rendered virtual reality image for the purpose of confirming the construction result in advance during the interview process with the design company 12 .

The client 13 accesses the system 10 from his device, creates a rendering virtual reality drawing, moves on the drawing through user input, and the color or material of design objects such as floor objects, wall objects and window objects, Details such as textures can be checked more realistically by moving directly in the virtual reality space through your device.

The client 13 can create a rendering virtual reality drawing through his or her mobile device, and directly view details such as color, finish, material, and texture of the architectural design target space through the rendering virtual reality image 330 . It can be verified close to reality.

4 is a diagram for explaining a process of generating a 3D structure drawing based on a 2D design drawing according to some embodiments.

Referring to FIG. 4 , the process of generating a 3D structural drawing in which the design objects of the 2D design drawing are arranged in 3D space by the processor 220 performing 3D mapping on the 2D design drawing for the architectural design object in the device 200 is It is described in more detail.

In the 3D mapping process 410, a 2D design drawing in the form of a DXF file may be converted into a 3D structure drawing in the form of an OBJ file through detailed steps. In the conversion process, shape/size recognition, data filtering, and abstraction processes may be performed.

In addition, comparison contents of the DXF file 420 and the OBJ file 430 before and after 3D mapping are shown. Since the DXF file 420 has high compatibility, it can be easily converted to the OBJ file 430, and the OBJ file 430 can be provided in a rather light form through an optimization algorithm, so that it is smooth even on a low-spec PC or mobile device. can be implemented

On the other hand, according to the 3D mapping process 440, some functions are limited in the process of generating the 3D structural drawing, and the 3D structural drawing 450 expressing only the 3D shape and structure of the 2D design drawing without details such as detailed material and texture. ) can be created. That is, when the processor 220 in the device 200 generates the 3D structural drawing 450 , 3D modeling for generating design objects and BIM objects, a material property, and a shader (Shader) At least some of the functions may be restricted.

Specifically, in the 3D mapping process 440 , normals, shader property values, CG/HLSL code, and an alternative version thereof may be completely removed or partially removed. In 3D modeling, normals expressing material bumps can be completely removed, and in Material and Shader, shader property values, CG/HLSL All but essential functionality of the code and an alternative version thereof may be removed.

As described above, as at least some of the 3D modeling, material, and shader functions are limited when the 3D structure drawing 450 is generated, the 3D structure drawing 450 is an OBJ file 430. Since it can be generated somewhat lightly in the form of , the functions of the apparatus 200 can be smoothly provided even in a low-spec PC or mobile device.

In addition to the indoor space as in the BIM virtual reality drawing 510, a BIM virtual reality drawing 520 is generated for a space such as a performance stage set, and the location and shape information of the BIM objects therein is subsequently transmitted through the BIM virtual reality image. It may be provided to the on-site construction company 11 .

6 is a diagram illustrating a method of generating a rendered virtual reality drawing based on a 3D structural drawing and an exemplary result thereof, according to some embodiments.

Referring to FIG. 6 , detailed processes 610 , 620 , and 630 of HD rendering for the 3D structural diagram 640 are illustrated, and a rendered virtual reality diagram 650 generated by the HD rendering is illustrated.

In the detailed process (610, 620, 630) of HD rendering, bump mapping is performed so that materials and textures of design objects can be realistically expressed, and light mapping and shade mapping are performed. As a result, the direction, intensity, and shading of light can be expressed with photorealistic level resolution.

Specifically, in the detailed process 610, light reflection and shading in relation to the user/graphic interface (UI/GI) may be processed in relation to the mesh, and in the detailed process 620, PBR (Physically Based Rendering), HDR ( High Dynamic Range) and Volumetric FX may be applied in relation to post-processing, and the result may be stored in a multimedia library in a detailed process 630 .

According to the detailed processes 610 , 620 , and 630 of HD rendering, the rendered virtual reality drawing 650 may be generated from the 3D structural drawing 640 . As illustrated, HD rendering may be performed indoors/outdoors, and in the rendering virtual reality drawing 650 , an architectural design target may be mainly an interior space inside a building in indoor architecture.

Bump mapping to represent the texture of design objects can be performed through the detailed process (610, 620, 630) of HD rendering, and aesthetics such as color and material are detailed at high resolution by the processing process for light and shading. After that, through the rendered virtual reality image based on the rendered virtual reality drawing 650 , the client 13 can realistically check the interior details presented by the design company 12 .

7 is a view for explaining a BIM virtual reality image and a rendered virtual reality image according to some embodiments.

Referring to FIG. 7 , a BIM virtual reality image 710 and a rendered virtual reality image 720 are illustrated. The rendering virtual reality image 720 may be provided to the client 13 through a mobile device as shown, and although not shown, the BIM virtual reality image 710 is also mobile at the construction site to the on-site construction company 11 It may be provided through a device.

A field worker of the on-site construction company 11 may generate a BIM virtual reality drawing through his/her mobile device, and may be provided with a BIM virtual reality image 710 based on this. The field worker may check the shape and structure of the BIM objects to be constructed at the construction site while changing the observation point in the BIM virtual reality image 710 .

On the other hand, the field worker may arbitrarily select objects from the BIM virtual reality image 710 to check the characteristic data of the object. As shown, the dimension of the BIM object corresponding to the plumbing equipment may be identified as 1.5 m, and the dimension of the design object corresponding to the staircase may be identified as 2 m.

The requesting customer 13 may also generate a rendered virtual reality drawing through his or her mobile device, and may be provided with a rendered virtual reality image 720 based on this. The requesting customer 13 may check the material and texture of which design objects are formed while changing the observation point in the rendered virtual reality image 720 .

8 is a view for explaining a process of providing an augmented reality image of an actual construction site according to some embodiments.

Referring to FIG. 8 , augmented reality images 810 and 820 that overlap and display characteristic data of design objects and BIM objects on a captured image of an actual construction site are shown.

The processor 220 in the device 200 provides an augmented reality image of the actual construction site by overlapping the characteristic data of the design objects and the BIM objects on the captured image of the actual construction site of the architectural design target by executing the instructions. It may be further configured to do so.

When the on-site construction company 11 intends to perform the construction work at the construction site, that is, the actual construction site of the architectural design target, if the indoor structure is complex, the site worker of the on-site construction company 11 knows exactly where It may not be easy to understand, and in a complex construction site, there may be confusion about the exact characteristics of the object to be constructed, such as dimensions, color, and material.

In the above case, if the characteristic data of design objects and BIM objects are overlapped and displayed on the image captured by the field worker's mobile device, the field worker can accurately determine the location of the construction site, or the size or color of the material to be constructed. Since it can be intuitively confirmed which one is, the construction accuracy can be greatly improved.

In the augmented reality image 810, the dimensions of the construction target object may be displayed overlapping the captured image. For example, in the case of piping construction, the field worker may check the exact location where the piping equipment is to be installed and its dimensions through the augmented reality image 810 . Also, in the augmented reality image 820 , the dimension and color of the wall of the captured image may be displayed. For example, a field worker who intends to paint a wallpaper can easily check characteristic data such as the size of the wall and the color of the wallpaper by using the augmented reality image 820 .

The processor 220, when providing the augmented reality image, performs a pre-processing process of matching the actual construction location with the BIM virtual reality drawing, and is arranged in a portion corresponding to the captured image in the BIM virtual reality drawing based on the pre-processing process Design objects and the BIM objects may be set as augmented reality objects, and characteristic data of the augmented reality objects may be overlapped on the captured image.

In order for the processor 220 to generate the augmented reality image by overlapping the characteristic data on the captured image, it may be required to perform a pre-processing process in advance. That is, when it is first identified how the actual construction site matches the BIM virtual reality drawing, the characteristic data of the objects captured in the captured image can be overlapped and displayed together.

After the pre-processing process is performed, the objects identified in the captured image may be set as augmented reality objects, and then the processor 220 calls the characteristic data of the corresponding objects from the BIM virtual reality drawing to obtain the captured image of the field worker. It can be displayed by overlapping with .

Meanwhile, the characteristic data may include data regarding the size and physical properties of design objects and BIM objects. As shown in the augmented reality images 810 and 820, the sizes of the objects may overlap, or physical properties such as materials and colors of the objects may overlap.

Referring to FIG. 9 , the first channel 910 and the second channel are feedback channels for real-time feedback between the participants of the architectural design collaboration, that is, the on-site construction company 11 , the design company 12 , and the client 13 . 920 is shown.

When the BIM virtual reality image and the rendered virtual reality image are provided, the processor 220 may also provide a feedback channel for real-time feedback between participants in the architectural design collaboration.

For example, when the on-site construction company 11 checks the shape and structure of BIM objects placed on the architectural design target with the BIM virtual reality image, voice feedback can be exchanged with the design company 12 in real time through the feedback channel. have.

According to him, when the design matters of the design company 12 are difficult to apply from the point of view of the on-site construction company 11, such an opinion can be transmitted to the design company 12 in real time through the feedback channel, The discrepancy between the actual construction result and the actual construction result can be resolved, and the problem of deteriorating productivity and profitability of architectural design due to the problem of determining who is responsible for the discrepancy can be solved.

Real-time feedback through a feedback channel may also be provided between the design company 12 and the client 13 . When the design of the design company 12 is changed, or when the client 13 changes his/her mind and requests a design change, the design company 12 and the client 13 view the rendered virtual reality image on their respective devices. At the same time, they can exchange opinions with each other in real time through the feedback channel.

In summary, the participants of the architectural design collaboration may include the design company 12, the on-site construction company 11, and the client 13, and the processor 220, when providing the BIM virtual reality image, design A first channel 910 for real-time feedback between the company 12 and the on-site construction company 11 can be provided, and when a rendered virtual reality image is provided, real-time between the design company 12 and the client 13 A second channel 920 for feedback may be provided.
