Abstract
Description
Technical Field
[0001] The present invention relates to a construction management system for managing construction on a construction object.
Background Art
[0002] In various types of construction such as driving, installing, and constructing a construction object according to the purpose, construction management is performed while monitoring the state of the construction object. For example, in the driving of steel pipe piles, conventionally, the guidance of the position and inclination of the pile has been performed by workers. Specifically, two surveyors aim at the pile from orthogonal directions with a transit, and the deviation between the current state and the design value is transmitted to the operator by a transceiver. Also, for the height management of the pile, one surveyor measures the height of the tip of the pile up to the stop with a level gauge and transmits it to the operator by a transceiver. On the other hand, in recent years, various systems for managing construction by displaying the site situation in 3D data have also been developed (see, for example, Patent Documents 1 and 2).

Summary of the Invention
Problems to be Solved by the Invention
[0004] In the conventional steel pipe pile driving method described above, operators guide and operate the piles to ensure their current position matches the design position, based on communication via transceivers from surveyors. However, they cannot visually confirm the actual situation, such as the relationship between the piles being driven and the design position. Consequently, operators have limited information to make decisions, which tends to reduce work efficiency and pile driving accuracy. Furthermore, while conventional systems that display 3D data use transparent wearable terminals or cameras to display the site situation, they require operators to be on-site or simply display the site situation, leaving room for improvement, especially in terms of integration with 3D data. Therefore, even if such a system were applied to steel pipe pile driving, there are many areas that operators cannot see, such as behind the piles being driven, raising concerns that they may not be able to grasp the movements of the workers.
[0005] This invention was made in view of the above-mentioned problems, and its purpose is to accurately grasp the situation in various construction processes. [Means for solving the problem]
[0006] (Modes of the invention) The following embodiments of the invention are illustrative of the configuration of the present invention and are described in separate sections to facilitate understanding of the diverse configurations of the present invention. Each section does not limit the technical scope of the present invention, and while taking into consideration the best mode for carrying out the invention, the technical scope of the present invention may also include modifications to some of the components of each section, such as substitution, deletion, or addition of other components.
[0007] (1) A construction management system for managing construction work on a construction object, comprising: measuring means for measuring the condition of the construction object; 3D data generation means for generating a virtual site space that simulates the surrounding area of the construction site based on the environment of the surrounding area measured in advance, and generating a 3D model of the construction object based on the measurement results of the measuring means; shooting means for taking pictures of the construction site; and display control means for switching between displaying the virtual site space and actual footage of the site taken by the shooting means, and displaying a 3D model of the construction object superimposed on the virtual site space or the actual footage of the site.
[0008] The construction management system described in this section is for managing various construction work on construction targets according to the purpose, and includes measurement means, 3D data generation means, imaging means, and display control means. The measurement means measures the state of the construction target, and depending on the properties of the construction target and the work performed on the construction target, for example, the position, orientation, and shape of the construction target are measured by the measurement means as the state of the construction target. The 3D data generation means generates a virtual site space that simulates the area around the construction site where the construction to be managed is performed, and a 3D model of the construction target. Specifically, the 3D data generation means generates a 3D data space that simulates the area around the construction site, including, for example, the terrain and existing structures around the construction site, based on the environment around the construction site that has been measured in advance, as a virtual site space that simulates the area around the construction site. Furthermore, the 3D data generation means generates a 3D model of the construction target based on the measurement results such as the position, orientation, and shape of the construction target measured by the measurement means.
[0009] The shooting means is used to capture images of the construction site and acquire live video footage of the site. For example, it is installed within or near the construction site to photograph the construction object and its surroundings. The display control means controls the content displayed to the user of this construction management system. It displays the virtual site space generated by the 3D data generation means and the live video footage of the site captured by the shooting means, switchable, for example, in response to user input. Furthermore, the display control means displays a 3D model of the construction object generated by the 3D data generation means overlaid on the displayed virtual site space or live video footage. To this end, the display control means grasps the relationship between the location of the construction site represented by the virtual site space, the location of the construction site shown in the live video footage, and the location within the construction site where the 3D model of the construction object should be displayed, using some appropriate method, and aligns and displays them.
[0010] This allows for the display of not only a virtual site space and a 3D model of the construction object overlaid on it, but also live-action video footage of the actual construction site, alongside the 3D model of the construction object. This results in a more realistic representation of the real world. Furthermore, objects that cannot be fully displayed in the 3D model due to frequent movement and changes during construction, such as workers, heavy machinery, and guide materials, as well as all objects within the camera's field of view, including the construction object and existing structures, are displayed in the live-action video footage. This allows for accurate understanding of the situation in various construction processes. Consequently, depending on the work being done on the construction object, for example, position and orientation management and shape management can be performed with greater precision, improving work efficiency and the accuracy of the finished product. Moreover, accurate understanding of the site conditions improves the safety of various tasks.
[0011] (2) A construction management system in which the photographing means is a 360-degree camera as described in item (1) above. The construction management system described in this section uses a 360-degree camera to capture images of the construction site, capturing a panoramic view centered on the camera's location. This expands the area displayed by the on-site video, allowing for the capture and display of areas that are difficult to photograph with conventional cameras, such as behind the construction target or existing structures. As a result, the invisible areas for users are reduced, leading to improved work efficiency, construction accuracy, and safety.
[0012] (3) In the above item (1), a plurality of the shooting means are installed, and the display control means selects a shooting means from the plurality of shooting means to display the actual on-site video when displaying the actual on-site video. The construction management system described in this section involves the installation of multiple cameras within or near the construction site to capture images of the construction site. The display control system selects which camera to display the live video footage from among the multiple cameras. As a result, live video footage of the site taken from various viewpoints is displayed according to the user's selection. This allows for enhanced monitoring of specific locations for each task, or simultaneous monitoring of multiple locations while switching viewpoints.
[0013] (4) In item (1) above, the shooting means is a construction management system equipped with a GNSS module. The construction management system described in this section utilizes a GNSS module in the camera used to photograph the construction site, ensuring that its location information is reliably tracked even if the camera moves. Therefore, it can flexibly manage various construction projects and situations, such as when the camera is installed on a ship to manage construction on water, or when it is installed on heavy machinery to capture images.
[0014] (5) A construction management system used in the construction of pile driving work in item (1) above, wherein the object to be constructed is a pile, the 3D data generation means calculates guidance data for guiding the pile being driven to the design position based on the measurement results of the measurement means and pre-set design data, and the display control means displays the guidance data near the 3D model of the object to be constructed corresponding to the pile being driven, or near the image of the pile being driven in the actual site video. The construction management system described in this section is used for pile driving work, where the construction target is a pile such as a steel pipe pile. Therefore, the measurement means used to measure the condition of the construction target is one that measures the position and orientation of the pile, and based on the measurement results, the 3D data generation means generates a 3D model of the pile, which is the construction target.
[0015] Furthermore, the 3D data generation means calculates guidance data to guide the pile being driven to the design position based on the measurement results of the measurement means and the pre-set design data. Specifically, the 3D data generation means compares the position and orientation of the pile being driven, as measured by the measurement means, with the design data of that pile, and calculates the difference between the position and orientation of the pile being driven and the design data as guidance data, for example, using arrows to indicate direction or numerical values to indicate size. The display control means then displays the calculated guidance data in the vicinity of the 3D model of the construction object corresponding to the pile being driven, generated by the 3D data generation means, or in the vicinity of the image of the pile being driven included in the on-site live video. As a result, the guidance of the pile being driven is performed within a space close to the real world as seen in the on-site live video, further improving the safety and efficiency of the work and the accuracy of the pile's construction.
[0016] (6) In the above item (1), the 3D data generation means generates at least one 3D model from among the construction target object in a completed state calculated from design data, an existing construction object that has already been completed, an existing structure around the construction site, and the ground configuration around the construction site, and the display control means is a construction management system that switches the display / hide of the 3D model of the construction target object and the at least one 3D model, respectively. The construction management system described in this section uses a 3D data generation means to generate 3D models as follows: The 3D data generation means generates at least one 3D model from among the construction target in its completed state, existing construction structures, existing structures around the construction site, and the ground structure around the construction site.
[0017] Here, the 3D model of the construction target in its completed state is generated based on pre-set design data of the construction target, while existing construction targets are those that have already been completed at the construction site, and their 3D models are generated based on data measured by measurement means during their construction or their design data. The 3D models of existing structures and ground configurations around the construction site are generated based on pre-measured information about the area around the construction site, and may be generated as part of a virtual site space that simulates the area around the construction site. The display control means allows the user to switch between displaying / hiding the 3D model of the construction target generated by the 3D data generation means and at least one of the aforementioned 3D models from among the construction target in its completed state, existing construction targets, existing structures around the construction site, and ground configurations around the construction site. This allows for various display patterns, such as switching the video of the construction target in progress to only the video of the construction target included in the live site video, or hiding unnecessary 3D models depending on the situation. Therefore, in various construction processes, the condition of the objects being constructed can be grasped more accurately, leading to improvements in work efficiency, precision, and safety. [Effects of the Invention]
[0018] Since the present invention has the above-described configuration, it is possible to accurately grasp the situation in various construction operations.

Embodiments for Carrying Out the Invention
[0020] Hereinafter, embodiments for carrying out the present invention will be described based on the accompanying drawings. Here, detailed description of the same parts or corresponding parts as in the prior art will be omitted, and the same parts or corresponding parts throughout the drawings are denoted by the same reference numerals. FIG. 1 schematically shows an example of the configuration of a construction management system 10 according to an embodiment of the present invention for managing various construction operations such as driving, installing, and constructing a construction object 40 (see FIG. 2) according to the purpose. As shown in the figure, the construction management system 10 includes measurement means 12, 3D data generation means 18, imaging means 22, and display control means 30. In this embodiment, as shown in FIG. 2, pile driving work performed on water (sea) will be described as an example of the management target. In this case, the construction object 40 is a pile 40A such as a steel pipe pile.
[0021] To briefly explain the pile driving work shown in Figure 2, in pile driving work, multiple piles 40A are driven into the seabed to support structures and facilities necessary for marine development and coastal development. The piles 40A are driven using guide materials (not shown) and pile driving vessels 48 such as crane ships equipped with pile driving machines 50. In pile driving work, in order to drive each of the piles 40A into the design position, it is necessary to monitor whether the piles 40A being driven are being driven into the design position, and if they are deviating from the design position, it is necessary to guide the piles 40A being driven to the design position. To manage such pile driving work at sea, the construction management system 10 according to an embodiment of the present invention is applied.
[0022] Referring to Figures 1 and 2, the measuring means 12 measures the state of the object to be constructed 40. In this embodiment, the state of the pile 40A, which is the object to be constructed 40, is measured, including the position, inclination, and height of the pile 40A during driving. For this purpose, the measuring means 12 in this embodiment includes three total stations 14A to 14C, one of which is a prism type, and the other two total stations 14B and 14C are non-prism types. The prism type total station 14A measures the height of the pile 40A during driving. It acquires height information of the pile 40A by sighting a tracking prism 52 that is pre-attached near the upper end of the pile 40A (such as the hammer portion of the pile driver 50).
[0023] In contrast, the two non-prism total stations 14B and 14C measure the displacement of the planar position of the pile 40A during installation. Each total station is designed to sight and measure at two predetermined measurement points on the pile 40A, for a total of four points. These three total stations 14A to 14C are installed at fixed locations, such as on the quay, near the construction site 44 where the pile installation work is being carried out. The data measured by the measurement means 12 (the three total stations 14A to 14C) is transmitted to the 3D data generation means 18 via any wireless or wired communication means.
[0024] The 3D data generation means 18 generates various 3D models and the like for display on the management screen 60 (see Figure 3) presented to users of the construction management system 10, as will be described later. Specifically, the 3D data generation means 18 generates a virtual site space that mimics the area around the construction site 44, a 3D model 62 of the construction object 40 under construction, a 3D model 68 of the construction object 40 in a completed state, a 3D model 70 of the existing construction object 40 which has already been completed, a 3D model of existing structures around the construction site 44, and a 3D model 74 of the ground structure around the construction site 44, some of which are shown in Figure 3. The virtual site space that mimics the area around the construction site 44 is generated based on environmental data such as the terrain and structures around the construction site 44 that have been measured in advance. If terrain information around the construction site 44 is publicly available, it may be used at this time.
[0025] The 3D model 62 of the construction object 40 under construction is generated based on the measurement results of the measurement means 12. In this embodiment, the 3D model 62 of the pile 40A being driven is generated based on the measurement results of three total stations 14A to 14C and the shape data of the pile 40A. The 3D model 62 of the pile 40A being driven is generated by calculating the pile center coordinates etc. from the measurement results of the three total stations 14A to 14C, but since this method is conventionally known, a detailed explanation is omitted here. The generated 3D model 62 of the pile 40A reflects information such as the position, height, and inclination of the pile 40A being driven. The 3D model 68 of the construction object 40 in the completed state is generated based on design data such as the position where the pile 40A being driven should be driven.
[0026] For the 3D model 70 of the existing structure, which is the construction target 40, the final 3D model generated as the 3D model 62 of the pile 40A being driven, as described above, when each pile 40A is being driven, may be used. Alternatively, if each pile 40A is driven accurately, the 3D model 70 of each pile 40A as an existing structure may be generated based on the design data of those piles 40A. The 3D model of the existing structure around the construction site 44, and the 3D model 74 of the ground structure (geological layers, layer thickness, etc.) around the construction site 44 are generated based on the previously measured data of the existing structure and ground structure around the construction site 44. These two 3D models may be generated as part of the virtual site space described above. Furthermore, depending on the construction site 44, a 3D model showing the sea level and point cloud data of the ground elevation at the site may also be generated. The virtual site space and various 3D models generated by the 3D data generation means 18 are embedded with coordinate data indicating their respective positions, based on information about the surrounding construction site 44 that has been measured in advance and the measurement results of the measurement means 12.
[0027] Furthermore, the 3D data generation means 18 also calculates guidance data 66 (see Figure 3) for guiding the pile 40A being driven to the design position. This guidance data 66 is calculated based on the pre-set design data of the pile 40A being driven and the measurement results of the three total stations 14A to 14C, which are the measurement means 12. In this embodiment, as shown in Figure 3, the guidance data 66 is calculated as arrows indicating the direction in which the pile 40A being driven should move, and the amount of movement in the direction of each arrow. This guidance data 66 is calculated from the comparison result between the current state of the pile 40A being driven, as grasped from the measurement results of the three total stations 14A to 14C, and the design data indicating the position in which the pile 40A should be driven. However, since this method is conventionally known, a detailed explanation is omitted here.
[0028] The 3D data generation means 18 consists of any hardware, such as a notebook personal computer, and software installed thereon. The 3D data generation means 18 is installed at any location, such as the operator's room of a pile-driving vessel 48. Various 3D models and guidance data 66 generated or calculated by the 3D data generation means 18 are transmitted to the display control means 30 via any wireless or wired communication means. Note that in Figure 2, for the sake of illustration, the 3D data generation means 18 is not shown, and the photographing means 22 and display control means 30, which will be described later, are also not shown.
[0029] Returning to Figures 1 and 2, the shooting means 22 is for capturing on-site live video 64 (see Figure 3) of the construction site 44. In this embodiment, two 360-degree cameras 24 equipped with GNSS modules 26 are used as the shooting means 22. Each of these 360-degree cameras 24 captures omnidirectional video centered on its installation position, and the GNSS module 26 determines its position at the time of shooting. Such 360-degree cameras 24 are installed in or near the construction site 44 to capture, for example, the area around the pile 40A being driven, the area around the guide material used for driving, the area around the pile driver 50, and a wide area within the construction site 44. As described above, the 360-degree cameras 24 in this embodiment may be attached to moving objects such as the driving ship 48, other vessels, or the pile driver 50, as the GNSS module 26 determines their position at the time of shooting. In this embodiment, the shooting data and position data of each 360-degree camera 24 are transmitted in real time to the display control means 30 via any wireless communication means such as Wi-Fi (registered trademark) or any wired communication means such as a USB cable.
[0030] Furthermore, if it is not necessary to monitor the construction site 44 in real time using the data captured by the shooting means 22, for example, recorded data of the construction site 44 previously captured by the shooting means 22 may be input to the display control means 30 via any memory or the like. Also, the shooting means 22 may be a camera other than a 360-degree camera, in which case the orientation of the shooting means 22 is adjusted and installed so as to capture the desired location within the construction site 44 as described above. Moreover, the shooting means 22 does not have to be equipped with a GNSS module 26, in which case the shooting means 22 is installed in a fixed position, and the installation position of the shooting means 22 is recorded and input to the display control means 30.
[0031] The display control means 30 controls the content displayed on the management screen 60, as shown in Figure 3, which is presented to the user of the construction management system 10, and may itself perform the display. Specifically, the display control means 30 generates the management screen 60 by combining various data generated or calculated by the 3D data generation means 18 and data captured by the shooting means 22. First, the display control means 30 displays the virtual site space generated by the 3D data generation means 18 and the actual site video 64 captured by the shooting means 22 as the background video of the management screen 60, switchable between them. For this reason, the virtual site space and the actual site video 64 in the management screen 60 are aligned with each other based on the position data embedded in the virtual site space and the position data of the actual site video 64 at the time of shooting. In this case, if the shooting means 22 does not have a GNSS module 26, the installation position of the shooting means 22, which is input in advance as described above, is used to align the actual site video 64. Such alignment may be fine-tuned by adjusting the base point (position and height) of the shooting means 22 that captured the on-site live video 64 in the virtual on-site space.
[0032] The background video switching described above is performed by the user operating the background switching input unit 82, and Figure 3 shows the state in which the on-site live video 64 is selected as the background video. Therefore, the on-site live video 64 includes the pile driving ship 48, the pile driving machine 50, the existing structure 54, etc., and the state of ships navigating in the surrounding area can also be confirmed. When the on-site live video 64 is displayed as the background video, the user can freely change the display direction within the omnidirectional video captured by the 360-degree camera 24, for example, by using the mouse. Furthermore, since two 360-degree cameras 24 are used in this embodiment, the viewpoint switch of which 360-degree camera 24's on-site live video 64 to display is performed by the user operating the background switching input unit 82.
[0033] Furthermore, the display control means 30 displays various 3D models generated by the 3D data generation means 18 overlaid on the virtual site space or actual site footage 64 displayed as background footage. For this reason, the various 3D models are aligned with the virtual site space or actual site footage 64 using the position data embedded in each of them. The management screen 60 in Figure 3 displays a 3D model 62 of the construction object 40 under construction (piles 40A being driven), a 3D model 68 of the construction object 40 in a completed state (the state after the driving of the piles 40A has been completed), a 3D model 70 of an existing construction object 40 (piles 40A that have already been driven), and a 3D model 74 of the ground structure around the construction site 44. Furthermore, the management screen 60 also displays 3D models 76 of the completed state of the unconstructed construction targets 40 (piles 40A) that are yet to be constructed (driven). These 3D models 76 are generated by the 3D data generation means 18 based on the design data of each unconstructed pile 40A.
[0034] Each of the aforementioned 3D models can be switched between being displayed and hidden under the control of the display control means 30. In this embodiment, the slider displayed on the display switching input unit 80 is operated by the user to adjust the contrast of each 3D model in the management screen 60, and is controlled to be hidden when it is set to the lightest. Specifically, the slider for "Piles being driven" on the display switching input unit 80 adjusts the contrast of the 3D model 62 of the piles 40A being driven, and the slider for "Completed piles" adjusts the contrast of the 3D model 70 of the piles 40A that have been driven. In addition, the slider for "Design piles" adjusts the contrast of the 3D model 68 of the piles 40A that have been driven and the 3D model 76 of the piles 40A that have not yet been driven and have been completed, and the slider for "Soil column diagram" adjusts the contrast of the 3D model 74 of the ground structure. In this embodiment, the "sea surface" slider also adjusts the display of the 3D model of the sea surface at the construction site 44.
[0035] Furthermore, the display control means 30 displays guidance data 66 calculated by the 3D data generation means 18 near the 3D model 62 of the pile 40A being driven. As described above, in this embodiment, the 3D data generation means 18 calculates arrows indicating the direction in which the pile 40A being driven should be moved, and the amount of movement in the direction of each arrow. Therefore, on the management screen 60 in Figure 3, the arrows and the amount of movement are displayed as guidance data 66 above and below the 3D model 62 of the pile 40A being driven. If the 3D model 62 of the pile 40A being driven is hidden by user operation, the guidance data 66 will be displayed near the image of the pile 40A being driven included in the on-site live video 64.
[0036] The display control means 30 consists of any hardware, such as a notebook personal computer, and software installed thereon. If the display control means 30 consists of a computer equipped with a display, the management screen 60 as shown in Figure 3 may be displayed on it. Alternatively, regardless of whether the display control means 30 is equipped with a display, the management screen 60 as shown in Figure 3 may be displayed on another display device connected to the display control means 30. The display control means 30 is installed in any location, such as the operator's room of a pile-driving vessel 48.
[0037] Herein, the construction management system 10 according to the embodiment of the present invention is not limited to the configuration described above, and can be configured appropriately according to the construction content, the properties of the construction object 40, the conditions of the construction site 44, etc. For example, the 3D data generation means 18 and the display control means 30 shown in Figure 1 are shown separated into functional units for the sake of explanation, so when actually constructing the construction management system 10, they may be configured as one device or divided into two or more devices. In addition, the measurement means 12 may use any appropriate measuring instrument according to the properties of the construction object 40 to be measured and the parameters to be measured. Furthermore, the number of imaging means 22 may be one or three or more. Moreover, the construction management system 10 according to the embodiment of the present invention is not limited to application to pile driving work on water (at sea), but is applicable to various constructions, whether on water or on land, for driving, installation, construction, and other arbitrary work on construction objects 40 according to the purpose.
[0038] Now, according to the embodiment of the present invention having the above configuration, the following effects can be obtained. That is, the construction management system 10 according to the embodiment of the present invention is for managing various construction work on a construction target object 40 (see Figure 2) according to the purpose, and as shown in Figure 1, it includes a measuring means 12, a 3D data generation means 18, a shooting means 22, and a display control means 30. The measuring means 12 measures the state of the construction target object 40, and depending on the properties of the construction target object 40 and the work performed on the construction target object 40, for example, the position, orientation, and shape of the construction target object 40 are measured by the measuring means 12 as the state of the construction target object 40. The 3D data generation means 18 generates a virtual site space that simulates the area around the construction site 44 (see Figure 2) where the construction to be managed is performed, and a 3D model 62 (see Figure 3) of the construction target object 40. Specifically, the 3D data generation means 18 generates a 3D data space that simulates the area around the construction site 44, including, for example, the terrain and existing structures around the construction site 44, based on the environment around the construction site 44 that has been measured in advance. The 3D data generation means 18 also generates a 3D model 62 of the construction object 40 based on the measurement results such as the position, orientation, and shape of the construction object 40 measured by the measurement means 12.
[0039] The shooting means 22 is for capturing images of the construction site 44 and acquiring on-site live video 64 (see Figure 3). It is installed within or near the construction site 44 to capture images of the construction object 40 and its surroundings, for example. The display control means 30 controls the content displayed to the user of the construction management system 10. It displays the virtual site space generated by the 3D data generation means 18 and the on-site live video 64 captured by the shooting means 22 in a switchable manner, for example, in response to user input to the background switching input unit 82 shown in Figure 3. Furthermore, as shown in Figure 3, the display control means 30 displays a 3D model 62 of the construction object 40 generated by the 3D data generation means 18 overlaid on the displayed virtual site space or on-site live video 64. Therefore, the display control means 30 grasps, by some appropriate means, the relationship between the position of the construction site 44 represented by the virtual site space, the position of the construction site 44 shown in the live video footage 64, and the position within the construction site 44 where the 3D model 62 of the object to be constructed 40 should be displayed, and then aligns and displays them.
[0040] This allows not only the 3D model 62 of the construction object 40 overlaid on the virtual construction site space, but also live-action video footage 64 showing the actual construction site 44 to be displayed together with the 3D model 62 of the construction object 40, making it possible to represent a space that is closer to the real world. Furthermore, all objects located within the shooting range of the shooting means 22, including workers, heavy machinery, and guide materials that cannot be fully displayed in the 3D model due to frequent movement and changes during construction, as well as the construction object 40 and existing structures 54, can be displayed using live-action video footage 64. For example, when applied to construction at sea, ships sailing around the construction site 44 can also be displayed. This makes it possible to accurately grasp the situation in various construction projects. Consequently, depending on the work performed on the construction object 40, for example, position and orientation management and shape management can be performed with high precision, thereby improving work efficiency and the accuracy of the finished product. Furthermore, by accurately grasping the site conditions, it is possible to improve the safety of various tasks.
[0041] Furthermore, in the construction management system 10 according to the embodiment of the present invention, the shooting means 22 for photographing the construction site 44 is a 360-degree camera 24, which allows for the capture of a 360-degree view centered on the installation position of the shooting means 22. This widens the range displayed by the on-site live video 64, allowing for the capture and display of areas that are difficult to photograph with a normal camera, such as behind the construction object 40 or existing structures. As a result, the invisible areas for the user can be reduced, and work efficiency, construction accuracy, and safety can be further improved.
[0042] Furthermore, in the construction management system 10 according to the embodiment of the present invention, multiple (two in Figure 1) shooting means 22 (360-degree cameras 24) for photographing the construction site 44 are installed within or near the construction site 44. When displaying the live video footage 64 of the site, the display control means 30 operates, for example, the background switching input unit 82 shown in Figure 3, to select the shooting means 22 that will display the live video footage 64 from among the multiple shooting means 22. This allows the user to select and display live video footage 64 of the site taken from various viewpoints, so that, for example, monitoring of locations that need to be grasped in detail for each task can be strengthened, or monitoring of multiple locations simultaneously while switching viewpoints can be performed.
[0043] In addition, the construction management system 10 according to an embodiment of the present invention includes a GNSS module 26 in the imaging means 22 (360-degree camera 24) that photographs the construction site 44, so that even if the imaging means 22 moves, its position information can be grasped without any problems. For this reason, it is possible to flexibly manage various construction and situations, such as installing the imaging means 22 on a ship to manage construction on the water, or installing the imaging means 22 on heavy machinery to take photographs.
[0044] Furthermore, the construction management system 10 according to the embodiment of the present invention is used for pile driving work in which the object to be constructed 40 is a pile 40A such as a steel pipe pile, as shown in Figure 2. For this reason, the measurement means 12 for measuring the state of the object to be constructed 40 is a total station 14A to 14C that measures the position and orientation of the pile 40A, and based on the measurement results, the 3D data generation means 18 generates a 3D model 62 of the pile 40A, which is the object to be constructed 40. The 3D data generation means 18 also calculates guidance data 66 (see Figure 3) for guiding the pile 40A to the design position during driving, based on the measurement results of the measurement means 12 and pre-set design data.
[0045] Specifically, the 3D data generation means 18 compares the position and orientation of the pile 40A being driven, as measured by the measurement means 12, with the design data of the pile 40A. The difference between the position and orientation of the pile 40A being driven and the design data, obtained as a result of this comparison, is calculated as guidance data 66, for example, using arrows to indicate direction or numerical values to indicate size. The display control means 30 then displays the calculated guidance data 66 near the 3D model 62 of the construction target object 40 corresponding to the pile 40A being driven, which is generated by the 3D data generation means 18, or near the image of the pile 40A being driven included in the on-site live video 64. This allows the guidance of the pile 40A being driven to be performed within a video of a space close to the real world provided by the on-site live video 64, thereby further improving the safety and efficiency of the work and the accuracy of the finished pile 40A.
[0046] Furthermore, in the construction management system 10 according to an embodiment of the present invention, the 3D data generation means 18 generates the following 3D models. That is, the 3D data generation means 18 generates at least one 3D model from among the construction target object 40 in a completed state, existing construction objects, existing structures around the construction site 44, and the ground structure around the construction site 44. Figure 3 shows some of these. Here, the 3D model 68 of the construction target object 40 in a completed state is generated based on pre-set design data of the construction target object 40, and the existing construction objects are construction target objects 40 that have already been constructed at the construction site 44, and their 3D models 70 are generated based on data measured by the measurement means 12 during their construction or their design data. The 3D models 74 of the existing structures around the construction site 44 and the 3D model 74 of the ground structure are generated based on pre-measured information about the area around the construction site 44, and may be generated as part of a virtual site space that simulates the area around the construction site 44.
[0047] The display control means 30 allows the user to switch the display / hide status of the following 3D models generated by the 3D data generation means 18: the 3D model 62 of the construction object 40, the 3D model 68 of the construction object 40 in a completed state, the 3D model 70 of existing structures, the 3D model of existing structures around the construction site 44, and the 3D model 74 of the ground structure around the construction site 44, for example, via the display switching input unit 80 shown in Figure 3. This allows for various display patterns, such as switching the video of the construction object 40 during construction to only the video of the construction object 40 included in the live site video 64, or hiding unnecessary 3D models depending on the situation. As a result, the status of the construction object 40 and other elements can be grasped more accurately in various construction projects, improving work efficiency, accuracy, and safety.
