[0004] Incidentally, to improve the linkage between design data (BIM data) and measurement data in order to manage discrepancies between design and construction, it is necessary to reduce the errors between them. However, measurement data is also measured based on previous measurement data, so errors accumulate. At the same time, discrepancies between BIM data and measurement data also accumulate. To manage this, it is desirable to be able to track when and how the measurement data linked to BIM data was created, while the measurement data and BIM data are linked.

[0005] Therefore, the purpose of this disclosure is to realize a system that has traceability for BIM data linked to stored measurement data and enables smooth utilization of BIM data linked to measurement data. [Means for solving the problem]

[0011] First, BIM (Building Information Modeling) is a building information model that combines building attribute information, such as the names and floor areas of rooms, the specifications and performance of materials and components, and finishes, in addition to primarily 3D geometric information created electronically on a computer. The use of BIM in various aspects of the construction industry is expected to improve productivity through the realization of high-quality, high-precision building production and maintenance, a highly efficient lifecycle, and the value of buildings as social assets through the widespread use of big data and integration with infrastructure platforms. The introduction of BIM is expected to improve the efficiency and performance of entire construction projects, including improved design quality, cost reductions, shortened construction periods, and smoother communication between stakeholders. In recent years, BIM has been increasingly used, particularly in public works projects, and is attracting attention as an important method for promoting digital transformation in the construction industry.

[0012] BIM data has various standards, but it is a digitalized version of geometric information such as the shape and dimensions of a building, as well as non-geometric information such as the specifications and performance of components (parts), material and component part numbers, and costs. Figure 1 shows an example of BIM data. For example, geometric data may include geometric shapes, positions, and directions, attribute data may include identification information, dimensions, materials, performance, and costs, and related data may include hierarchical relationships, connection relationships, and spatial relationships.

[0013] In order to utilize this BIM data in relation to construction and maintenance in the real world, it is preferable to link it with data that has actually been measured, i.e., measurement data. In this disclosure, BIM data linked with measurement data will be referred to as measurement BIM data. Measurement data linked to BIM data may include, for example, the following: Point data: 3D point data and 3D point cloud data of buildings acquired by optical wave measurement devices such as TS or laser scanners. Coordinate information is attached. RGB color information may also be attached. · Feature point data: Data on feature points among point data. Image data: RGB image data with location information of the measurement point obtained during scanning. · Construction error data: Data showing the error between the BIM model design position of components, etc. and the actual construction position of components, etc. This allows the current state of the object to be digitized with high accuracy and can be used as advanced BIM data.

[0014] Figure 2 shows an example of measurement BIM data linked in this way. Measurement BIM data is data that adds measurement data from real-world measurements related to the BIM data to general BIM data, and may, for example, have attribute information and shape information just like BIM data. For example, shape information acquired by measurement may have shape information that is 3D information composed of a group of actual measurement points such as a measurement model. Furthermore, the attribute information acquired and added by measurement may include at least the coordinates of the measurement point, the measurement date and time of the measurement point, and the measurement standard used as the basis for measuring the measurement point (including at least the name of the parent generation measurement point and the measurement point identifier of the measurement point).

[0015] Utilizing such measurement BIM data allows for the identification and confirmation of boundary points based on actual measurements. Boundary points are identified using surveyed public reference points. Boundary points have legal significance in indicating land ownership and boundaries, and are sometimes physically indicated using boundary markers such as stakes and ink. In addition, relief reference points are installed to ensure a certain distance from boundary points. These physical boundary indicators are also measured to build a measurement BIM data database. In other words, measurement BIM data contains information on at least the above types of reference points: public reference points, boundary points, and relief reference points. As such, reference points in measurement BIM data are generated by deriving one point from another. As the deriving of reference points accumulates, construction error data in the measurement BIM data also accumulates, leading to an accumulation of discrepancies between real and virtual spaces. To ensure opportunities to correct or confirm such accumulated errors, it is necessary to be able to trace and confirm when, how, and from what origin each reference point in the measurement BIM database was created in a building information model management system. This disclosure describes such a building information model management system.

[0016] FIG. 3 shows a network configuration diagram of the architectural information model management system of the present disclosure. The architectural information model management system 1 may include a first computer device 100A, a second computer device 100B, a first management server 100S1 which is also a single computer device, and a first surveying device 200A, all connected to a network NW. The first computer device 100A, the second computer device 100B, and the first management server 100S1 may be computer devices such as those described in FIG. 4 below. The first surveying device 200A may be a surveying device capable of measuring at least the coordinates of a reference point and the date and time, and may be, for example, an optical measurement device such as a total station (TS), a 3D scanner, or the like.

[0017] 4 shows the hardware configuration of a typical computer device that can be used as a first computer device 100A, a second computer device 100B, and a first management server 100S1 that is also a single computer device. The computer device 100 can execute predetermined processes through collaboration between software and hardware resources by having the processor 114 execute an application program based on application data stored in the storage device 115. The storage device 115 may store operating system data necessary for the computer device 100 to function as a general-purpose computer, and the operating system functions using the operating system data.

[0018] Such a computing device 100 may be any type of electronic device, such as, for example, a server computer, a desktop computer, a laptop computer, a portable or mobile device, a camera, a mobile phone, a smartphone, a tablet computer, a television, a wearable device (such as display glasses or goggles, a head-mounted display (HMD), a head-mounted spatial computing device, a watch, a headset, an armband, etc.), a virtual reality (VR) and / or augmented reality (AR) enabled device, a personal digital assistant, etc.

[0019] Input interface 112 and output interface 113 may be hardware devices that allow a user to input and output information to and from computer device 100 and / or other computer devices. Specific input devices that may constitute input interface 112 may include a keyboard, a mouse, one or more touch panel sensors, a microphone, etc. Similarly, output devices that may constitute output interface 113 may include a display, a monitor, a printer, a virtual space projection display, an augmented space projection display, a speaker, etc.

[0020] The communication interface 111 can communicate with other electronic devices using various types of electrical communication lines, including wired and wireless connections, such as wide area network connections via fiber optic networks or digital telephone lines, local wireless connections, short-range wireless communications, and satellite-based location systems.

[0021] Processor 114 may be one or more of any type of computer processing element, such as in the form of an integrated circuit or controller that performs processor operations, such as with a central processing unit (CPU). For example, processor 114 may be one or more single-core processors. Alternatively, processor 114 may be one or more multi-core processors having multiple independent processing units. Processor 114 may also include register memory for temporarily storing instructions being executed and associated data, as well as cache memory for temporarily storing recently used instructions and data. When multiple processors are used for processing, the same processor need not perform all of the processing.

[0022] The system may employ a cluster configuration in which multiple computing devices 100 are grouped and connected via a network. In this case, the same computing system may be installed in multiple locations. The specific locations and connection methods of these computing devices are not important, and they may even be located outside the country in which the user resides. Such a group of computing devices may be treated as a single cloud computing resource distributed across various data centers.

[0023] Next, the processing flow of the measurement BIM data output method using the architectural information model management system of the present disclosure is shown. Fig. 5 is a database schema diagram showing the structure of measurement BIM data with the minimum configuration required to output measurement BIM data of the present disclosure, Fig. 6 is a functional block diagram showing the minimum components for outputting measurement BIM data using the architectural information model management system of the present disclosure, and Fig. 7 is a flowchart showing the minimum processing flow of the measurement BIM data output method.

[0024] As shown in Figure 5, measurement BIM data contains at least a measurement point identifier, the coordinates of the measurement point, the measurement date and time of the measurement point, and some kind of reference point information. The measurement point identifier may be electronic data that can uniquely identify the measurement point, such as the name or ID of the measurement point. The coordinates of the measurement point may be electronic data that indicates coordinate values ​​in a specified coordinate system. The measurement date and time of the measurement point may be electronic data that indicates the measurement timing, such as the year, month, day, and time. The reference point may be information about the point used as the reference for the measurement.

[0025] Basically, it is not necessary to assign information such as first and second generations between measurement BIM data; it is sufficient to be able to output the parent-child relationship by processing the reference point information. With at least the reference point information, it is possible to find the parent. On the other hand, various ingenuity is required for child generations. For example, information that will become the child generation measurement BIM data can be assigned. Or parameters such as the number of generations can be added. Alternatively, it is possible to search child generations using a reverse reference search, or to devise a search query that allows child generations to be searched by self-joining. Furthermore, parent-child relationships can also be referenced by adopting a graph database as a non-relational database, where measurement BIM data is represented by nodes, edges, and properties.

[0026] Here, the difference between first-generation measurement BIM data and second-generation or later measurement BIM data is whether or not there is a parent measurement BIM data (reference point), but this does not mean that there are no reference points in first-generation measurement BIM data; reference points such as public reference points may exist. First-generation measurement BIM data simply means that there is no parent on the measurement BIM data.

[0027] These multiple pieces of measurement BIM data are constructed as a measurement BIM database. The measurement BIM database may be stored in a centralized or distributed manner in data storage of multiple computing devices, such as a first computer device and a first management server 100S1. In other words, a database management method generally referred to as a cloud solution may be adopted.

[0028] Using this measured BIM data, as shown in Figure 6, the generation output unit 116 of the building information model management system 1 outputs generation relationship information from the output interface 113 using the measurement point identifiers of the second-generation and subsequent measured BIM data input via the input interface 112 or other mechanical or automatic information processing. The generation output unit 116 may be a software program executed by application data installed on one of the computing devices that make up the building information model management system 1, or a function provided by an application program. The program may also be traded independently by being provided via a non-transitory storage medium such as the storage device mentioned above or an electronic communication line. This will be explained with reference to the flowchart in Figure 7.

[0029] 7, first, the measurement point identifier of the second-generation or later measurement BIM data is input by the input interface 112 operated by the user, or by mechanical, automatic information processing that reflects the user's intention (i.e., including intermediate information processing that is executed starting from the user's input operation). As a result, the system acquires the measurement point identifier of the second-generation or later measurement BIM data.

[0030] Next, in step S102, the generation output unit 116 searches and identifies the second or subsequent generation measurement BIM data having the input and acquired measurement point identifier from the measurement BIM database.

[0031] Next, in step S103, the generation output unit 116 identifies measurement BIM data that will be the parent generation from the reference point that will be the reference for the second-generation and subsequent measurement BIM data identified in step S102 above.

[0032] Next, in step S104, it is confirmed whether a parent generation of the identified parent generation measurement BIM data exists. If there is no parent generation of the measurement BIM data (it was first-generation measurement BIM data with no previous measurement BIM data) (No), the process is stopped and proceeds to the next step S105. If there is a parent generation (Yes), the process returns to step S103 and repeats the process until all parent generations are acquired.

[0033] In step S105, the generation output unit 116 uses the acquired measured BIM data of all generations to output the generation relationship information to the output interface 113. This ends the processing.

[0034] As described above, by using the architectural information model management system disclosed herein to output generation relationship information for measured BIM data, a system can be realized that has traceability to the BIM data linked to the stored measured data and can utilize BIM data linked to the measured data.

[0035] Below, we will show an example of how measured BIM data is constructed and how it can be referenced, using a simple example of the design of a building to be constructed on a certain site. Figures 8 and 9 are diagrams showing the process by which measured BIM data managed by the architectural information model management system disclosed herein is accumulated, simulating a plan view of a construction site or work site viewed from directly above.

[0036] Figure 8 partially repeats the outline above, but first, measurement data of the boundary points from public control points is registered. In actual surveying, if at least two public control points PRP1 and PRP2 shown in this figure are measured using a surveying device such as a total station, then a single boundary point B1, whose actual coordinates are unknown and placed in the BIM data, can be registered using the resection method. Boundary point B2 can be registered using a similar method, and boundary points BP1 and BP2 can be used to generate boundary line BL1. In this way, the relative distances from public control points PRP1 and PRP2 can be measured and registered, allowing the positions of boundary points BP1 and BP2 to be measured and managed. In this case, boundary point BP1 uses the public control point as its base point, and since there is no further parent-generation measured BIM data, it is the first-generation measured BIM data. At this point, boundary line BL1 is already derived from boundary points BP1 and BP2, and boundary points BP1 and BP2 are derived from public control points PRP1 and PRP2. As measurements accumulate from the first reference point in this way, there is a possibility that errors will also accumulate. Therefore, the inventors came up with the idea of ​​providing traceability to measurement BIM data with the concept of control point generation management. Specific generation management will be discussed later, but for now, we will continue to explain the installation of control points.

[0037] Next, an escape reference point is created from the boundary point. An escape reference point is a point that is calculated and set back a certain distance from the center line when determining the reference point during building construction, anticipating that the center line (described below) will be hidden by columns or walls. In this example, the point is set by measuring its position from the boundary point. Specifically, the measurement data for escape reference point ORP1, measured using boundary points BP1 and BP2 as reference points, is registered. Four escape reference points can be created in a similar manner. In this case, escape reference point ORP1 corresponds to the second-generation measured BIM data, with boundary points BP1 and BP2 as the parent generation.

[0038] Next, in Figure 9, the grid center line is created. The grid center line represents the center line of the walls of a building, etc. Once the relief reference point has been confirmed, the grid center line can be created using the relief reference point as the starting point. Specifically, measurement data for grid center line CLP1, one of the points that make up the grid center line, measured using relief reference points ORP1 and ORP2 as reference points, is registered. Multiple grid center point data can be registered in a similar way, and by connecting these, grid center line data can also be generated. In this case, grid center line CLP1 corresponds to the third-generation measured BIM data, with relief reference points ORP1 and ORP2 as the parent generation.

[0039] Next, a return mark is created from the center line. A return mark is a design line that is a specified distance away from the center line in the vertical direction. A return mark is set to serve as a reference for walls, columns, and other installed objects. For example, if a wall is placed directly above the center line (the center line of a building), it may disappear during construction, so a return mark is usually drawn parallel to the center line at a certain distance. Specifically, in this case, measurement data for return mark SOP1, which is offset a certain distance inward from the center line, can be registered. Line data for return mark can also be generated by registering multiple return mark point data in a similar manner. In this case, return mark SOP1 corresponds to the fourth-generation measurement BIM data, with the center line as the parent generation.

[0040] From this point on, it is possible to register next-generation reference points such as retaining wall marks and column centerlines. For the measured BIM data registered in this way, the above-mentioned generation relationship information can be output as follows: Figure 10 shows an example of a generation display when generation relationship information is visually output using a display as an example of the output interface 113.

[0041] In this figure, an example of a generation display is shown, with the vertical axis representing the generation number and the horizontal axis representing the measurement date (measurement timing including year, month, day, hour, minute, second, etc.), and each measurement point (reference point) is shown on a grid where the generation number and measurement date intersect. Arrows indicating the parent-child relationship from reference point to reference point are also displayed. For reference, a simulated plan view corresponding to the generation display example on the top is shown on the bottom.

[0042] In this way, by displaying the generations of measured BIM data, it is possible to determine at a glance how measurement errors may accumulate when utilizing measured BIM data.
