[0008] Hereinafter, embodiments of the present invention will be described in detail by way of example with reference to the drawings. However, the configurations, numerical values, processing flows, functional elements, etc. described in the following embodiments are merely examples, and are open to modification and alteration, and are not intended to limit the technical scope of the present invention to the following description.

[0009] [First embodiment] A construction management device 100 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5. An overview of building construction management using the construction management device 100 will be described with reference to FIG. 1. The construction management device 100 is a device that displays, on a display 140, a simulation site model 120 that represents the progress of construction at a building site 110 at a specified time, and appearance data 130 that represents the actual appearance of the construction site 110. The construction management device 100 is used, for example, for construction management of a building 150. Note that buildings whose construction is managed by the construction management device 100 are not limited to buildings, and may also be, for example, houses, sports facilities, roads, bridges, port facilities, dams, airports, etc.

[0010] First, the construction management device 100 creates three-dimensional model data 121 that is a three-dimensional model of the entire construction site 110 based on survey data 113 of the construction site 110 and its surrounding terrain 111, and of buildings 112 that exist at the construction site and its surroundings. The survey data 113 was obtained by surveying the construction site 110 before construction began. In other words, the three-dimensional model data 121 is a three-dimensional model of the construction site 110 before construction began.

[0011] Next, the construction management device 100 simulates the state of the construction site 110 at a specified time, for example, the current time, based on the construction plan data 160, the three-dimensional model data 121, and the three-dimensional model 122 of the construction machinery, and generates the simulation site model 120. In the simulation site model 120, a three-dimensional model 123 of the portion of the construction that is scheduled to be completed at a specified time during the construction period, and a three-dimensional model 122 of the construction machinery required for the construction work that is scheduled to be performed at that time, are arranged at the planned locations.

[0012] The construction site 110 is photographed in real time by at least one imaging device such as a fixed camera 131. The construction management device 100 acquires the video captured by the camera 132, i.e., appearance data 130 representing the actual appearance of the construction site 110, in real time.

[0013] Then, the construction management device 100 displays the simulation site model 120 and the appearance data 130 at a specified time during the construction period, i.e., at a time specified when the simulation site model 120 was created, on the display 140. The operator of the construction management device 100 can understand the progress of construction at the building site 110 by comparing the simulation site model 120 and the appearance data 130 displayed on the display 140. For example, by comparing the construction machinery 133 that is actually placed and the portion 134 where construction has actually been completed in the appearance data 130 with the three-dimensional models 122, 123 in the simulation site model 120, it is possible to understand whether the construction work at the building site 110 is progressing as planned.

[0014] 2A, the configuration of the construction management device 100 will be described. The construction management device 100 includes a three-dimensional model data creation unit 201, a construction plan data acquisition unit 202, a simulation site model generation unit 203, an appearance data acquisition unit 204, and a display control unit 205.

[0015] The three-dimensional model data creation unit 201 creates a three-dimensional model of the terrain 111 and the buildings 112 based on surveying data obtained by surveying the construction site 110 and its surrounding terrain 111, as well as the construction site 110 and the buildings 112 existing therein, and further creates three-dimensional model data 121 of the entire construction site 110 based on the three-dimensional models of the terrain 111 and the buildings 112.

[0016] Specifically, the three-dimensional model data creation unit 201 first creates three-dimensional models of the terrain 111 and the building 112 based on the survey data 113. Then, the three-dimensional model of the terrain 111 and the three-dimensional model of the building 112 are combined to create three-dimensional model data 121 of the entire construction site 110.

[0017] The survey of the terrain 111 and the buildings 112 may be carried out by workers or the like using rulers such as a straight ruler, a curved ruler, or a tape measure. Alternatively, workers or the like may carry out the survey using a transit, a theoride, a total station, or the like. Furthermore, the survey may be carried out using three-dimensional surveying such as aerial photogrammetry, airborne laser surveying, vehicle-mounted photo laser surveying, UAV photo point cloud surveying, UAV laser surveying, terrestrial laser surveying, airborne laser sounding, and multi-beam sounding. The terrain 111 and the buildings 112 may be surveyed separately, or the terrain 111 and the buildings 112 may be surveyed together.

[0018] The three-dimensional model data creation unit 201 may acquire survey data directly or indirectly from a surveying instrument. For example, the survey data acquired by the surveying instrument may be stored in a storage medium separate from the surveying instrument, and the survey data may be acquired from the storage medium. Alternatively, an operator may input the survey data into the construction management device 100 using an input device such as a keyboard, and the three-dimensional model data creation unit 201 may acquire the input survey data.

[0019] The construction plan data acquisition unit 202 acquires construction plan data 160 for construction work to be carried out at the construction site 110. The construction plan data 160 includes information such as the type, number, and location of construction machinery to be used, a blueprint for the building 150, and a schedule for the construction work to be carried out at the construction site 110. The construction plan data 160 may be created by a device other than the construction management device 100, for example, a device equipped with software required to create the construction plan data 160. An example of the aforementioned software is CAD (Computer Aided Design). The construction plan data acquisition unit 202 may acquire the construction plan data 160 directly or indirectly from a device other than the construction management device 100.

[0020] The simulation site model generation unit 203 simulates the state of the construction site 110 at a specified time based on the construction plan data 160, the three-dimensional model data 121, and the three-dimensional model 122 of the construction machinery used at the construction site 110, and generates the simulation site model 120.

[0021] Specifically, the simulation site model generation unit 203 generates a three-dimensional model 123 of the portion of the building 150 scheduled for completion at a specified time during the construction period based on the construction plan data 160. The simulation site model generation unit 203 also acquires information such as the type, number, and location of construction machinery required for the construction work being carried out at the specified time from the construction plan data 160. Next, the simulation site model generation unit 203 acquires a three-dimensional model 122 of the construction machinery included in the acquired information from a storage medium that stores three-dimensional models of all construction machinery used in the construction work being carried out at the building site 110. The three-dimensional models 122, 123 and the three-dimensional model data 121 are then arranged in a predetermined positional relationship planned in the construction plan data 160 to generate the simulation site model 120. The simulation site model 120 simulates the state of the construction site 110 if the construction work up to the specified time is carried out according to the construction plan data 160. Note that if the construction plan data 160 includes the three-dimensional model 122, it is not necessarily necessary to acquire the three-dimensional model 122 from the storage medium.

[0022] The appearance data acquisition unit 204 acquires appearance data 130 representing the actual appearance of the construction site 110 from a measuring device that measures the actual appearance of the construction site 110. The measuring device may be at least one of a three-dimensional scanner and an imaging device. An example of a three-dimensional scanner is a scanner equipped with a LiDAR (Light Detection and Ranging) sensor. The appearance data 130 may be video, still images, point cloud data, etc. The video and still images of the appearance data 130 may be captured using visible light, infrared light, ultraviolet light, etc.

[0023] In this embodiment, the measuring device is a fixed camera 131 installed at the construction site 110. The fixed camera 131 is an optical camera capable of capturing images of visible light, infrared light, ultraviolet light, etc. The orientation and magnification of the fixed camera 131 are also changeable.

[0024] The number of fixed cameras 131 may be one or more. It is preferable that the fixed cameras 131 are installed so that there are no blind spots at the construction site 110. The installation position of the fixed cameras 131 may remain the same throughout the construction period, or may be changed according to the progress of the construction. By changing the installation position of the fixed cameras 131 according to the progress of the construction, the fixed cameras 131 can be placed at positions at the construction site 110 where they can reliably capture images of areas where progress is desired to be confirmed.

[0025] As a measuring device, a camera mounted on a UAV (unmanned aerial vehicle) such as a drone may be used in combination with the fixed camera 131. By using a camera mounted on a drone or the like as a measuring device, it is possible to easily measure the appearance of any position on the construction site 110, so that, for example, it is possible to photograph places that cannot be photographed with the fixed camera 131, to photograph places that require more focus from a closer distance, or to photograph the construction site 110 from a bird's-eye view.

[0026] The appearance data acquisition unit 204 may acquire the appearance data 130 directly or indirectly from the measuring instrument. For example, the appearance data 130 measured by the measuring instrument may be stored in a storage medium separate from the measuring instrument, and the measurement data may be acquired from the storage medium.

[0027] The display control unit 205 displays the simulation site model 120 and the appearance data 130 on a predetermined display device. The predetermined display device is, for example, the display 140. The display device may also be a smartphone, a tablet terminal, or the like. FIG. 2B shows an example of a display screen 250 that the display control unit 205 displays on the display 140. On the display screen 250, the simulation site model 120 and the appearance data 130 are displayed side by side, specifically, side by side. The simulation site model 120 and the appearance data 130 may also be displayed vertically.

[0028] Comparing the simulation site model 120 and the exterior data 130 displayed on the display screen 250, it can be seen that the three-dimensional model 123 of the portion of the building 150 for which construction is scheduled to be completed in the simulation site model 120 is taller than the portion 134 of the building 150 for which construction has been completed in the exterior data 130. In other words, it can be seen that the portion that has been constructed in the simulation site model 120 is not yet constructed in the exterior data 130. Therefore, an operator looking at the display screen 250 can understand that the construction at the construction site 110 is behind schedule as planned in the construction plan data 160. If there is a delay in the progress of construction, the operator can take necessary measures to ensure the smooth progress of construction, such as adjusting the construction schedule or increasing the number of workers working at the construction site 110.

[0029] Furthermore, by comparing the simulation site model 120 with the appearance data 130, it is possible to determine whether, for example, the placement positions of the construction machinery 133 and the three-dimensional model 122 are different. In Fig. 2B, the placement positions of the construction machinery 133 and the three-dimensional model 122 are the same. Therefore, it can be seen that the construction work is progressing according to the construction plan data 160.

[0030] On the other hand, if the placement position of the construction machine 133 differs between the construction site 110 and the three-dimensional model 122, this may be due to, for example, the presence of an unexpected obstacle at the actual construction site 110, making it impossible to place the construction machine 133 at the planned location. Examples of obstacles include utility poles and roadside trees. Other examples of obstacles include debris of a previous building or rocks exposed by excavation work. When such an obstacle is present, the operator can promptly consider whether the obstacle can be removed, and whether the order of work processes to be performed at the construction site 110 or the access route for the construction machine 152, etc., needs to be changed from those planned in the construction plan data 160.

[0031] The following may also be considered as a reason why the placement positions of the construction machinery 133 and the three-dimensional model 122 differ: During construction work, it is discovered that an underground structure such as a sewer pipe is buried underground where the three-dimensional model 122 is placed, and the weight of the construction machinery 133 exceeds the upper limit of the weight of construction machinery that can be placed at that location. Even in such a case, the operator can promptly consider whether or not it is necessary to change the order of work processes to be performed at the construction site 110 or the access route for the construction machinery 152 from what was planned in the construction plan data 160.

[0032] Another possible cause is that construction machinery used for a construction project other than the construction being carried out at the construction site 110 is located near the construction site 110, and if the construction machinery 133 is located at the planned position, it may interfere with the construction machinery used for the other project. Even in such a case, the operator can consider in a timely manner whether or not it is necessary to change the order of the work processes to be carried out at the construction site 110 or the access route for the construction machinery 152 from what was planned in the construction plan data 160.

[0033] As described above, the appearance data 130 may be a visible light image, an infrared image, an ultraviolet image, or the like, but from the viewpoint of making it easier to compare the simulation site model 120 and the appearance data 130, it is preferable that the appearance data 130 be a visible light image. When the appearance data 130 is an infrared image, it is possible to determine whether there are any parts in the part 134 of the building 150 where construction has been completed that have a different temperature from the surrounding area. When a part that has a different temperature from the surrounding area is discovered, it is possible to promptly consider whether to take measures to prevent the temperature of that part from differing from the surrounding area, such as whether to apply insulation or heat-shielding treatment to that part.

[0034] The display control unit 205 may display the current simulation site model 120 in real time as the simulation site model 120, or may display a past simulation site model 120. The simulation site model 120 to be displayed may be one generated each time by the simulation site model generation unit 203. Furthermore, the simulation site model 120 to be displayed may be one selected from the simulation site models 120 for the entire period in the construction plan data 160 that have been generated in advance by the simulation site model generation unit 203.

[0035] Furthermore, the display control unit 205 may display the current appearance data 130 in real time as the appearance data 130, or may display past appearance data 130. When the current appearance data 130 is displayed in real time, first, the fixed camera 131 captures the appearance of the construction site 110 in real time. Then, the appearance data acquisition unit 204 acquires the video of the exterior of the construction site 110 captured in real time, i.e., the appearance data 130, in real time. Furthermore, the display control unit 205 displays the appearance data 130 acquired in real time in real time.

[0036] When displaying the current appearance data 130 in real time, it is preferable that the fixed camera 131 and the construction management device 100 are connected via a wireless or wired communication network. The fixed camera 131 and the construction management device 100 may be connected directly or via a repeater. The wireless communication network may be compatible with, for example, LTE (Long Term Evolution), a fourth-generation mobile communication system, a fifth-generation mobile communication system, satellite communication, Bluetooth (registered trademark), Wi-Fi (registered trademark), etc. The communication network connecting the fixed camera 131 and the construction management device 100 may be a combination of a wireless communication network and a wired communication network. Furthermore, when a communication standard with a relatively short communication distance, such as Bluetooth (registered trademark) or Wi-Fi (registered trademark), is used to connect the fixed camera 131 and the construction management device 100, one or more repeaters may be used between them.

[0037] When displaying past appearance data 130, as well as when displaying current appearance data 130 in real time, the fixed camera 131 and the construction management device 100 may be connected via a wireless or wired communication network.

[0038] When displaying past appearance data 130, fixed camera 131 and construction management device 100 do not need to be connected. For example, appearance data 130 acquired by fixed camera 131 may be stored in a storage medium, and construction management device 100 may acquire appearance data 130 from the storage medium. Fixed camera 131 or construction management device 100 may be equipped with the storage medium, or a device other than camera 132 and construction management device 100 may be equipped with the storage medium. Also, construction management device 100 may acquire appearance data 130 directly from fixed camera 131, and construction management device 100 may store the appearance data 130.

[0039] Additionally, a model viewpoint change controller 258a and an exterior viewpoint change controller 258b are displayed on the display screen 250. The model viewpoint change controller 258a is used to arbitrarily rotate the simulation site model 120 displayed on the display screen 250 and arbitrarily change the viewpoint from which the simulation site model 120 is viewed.

[0040] The exterior viewpoint change controller 258b is used to arbitrarily rotate the exterior data 130 displayed on the display screen 250 and arbitrarily change the viewpoint from which the exterior data 130 is viewed. The movement of the exterior viewpoint change controller 258b is linked to the movement of the fixed camera 131. In other words, by operating the exterior viewpoint change controller 258b, the orientation of the fixed camera 131 can be arbitrarily changed.

[0041] When the display control unit 205 displays past appearance data 130, it is preferable that the appearance data 130 acquired by the multiple fixed cameras 131 can be switched and displayed by operating the appearance viewpoint change controller 258b. By switching the appearance data 130 acquired by the multiple fixed cameras 131, the viewpoint of the appearance data 130 can be switched.

[0042] The model viewpoint change controller 258a and the exterior viewpoint change controller 258b are not linked and operate independently, meaning that the viewpoint for viewing the simulation site model 120 and the viewpoint for viewing the exterior data 130 can be changed separately.

[0043] Conversely, the model viewpoint change controller 258a and the exterior viewpoint change controller 258b may be configured to move in conjunction with each other. In other words, when one is moved, the other may also move in the same way. In this way, when the viewpoint of either the simulation site model 120 or the exterior data 130 is changed, the viewpoint of the other is also changed in conjunction with it, making it even easier to compare the simulation site model 120 and the exterior data 130.

[0044] The display screen 250 may display a viewpoint linkage switching button for switching between a state in which the model viewpoint change controller 258a and the appearance viewpoint change controller 258b are linked and a state in which they are not linked.

[0045] The display screen 250 may also display a model zoom controller for zooming in and out on the simulation site model 120, and an appearance zoom controller for zooming in and out on the appearance data 130.

[0046] The model scaling controller and the exterior scaling controller are not linked and operate independently, meaning that the simulation site model 120 and the exterior data 130 can be scaled separately.

[0047] Conversely, the model scaling controller and the appearance scaling controller may be designed to move in tandem. In other words, when one is moved, the other may move in the same way. In this way, when either the simulation site model 120 or the appearance data 130 is scaled, the other is also scaled in tandem, making it easier to visually compare the simulation site model 120 and the appearance data 130.

[0048] The display screen 250 may also display a scaling ratio linkage switching button for switching between a state in which the model scaling controller and the appearance scaling controller are linked and a state in which they are not linked.

[0049] A model seek bar 259a and an appearance seek bar 259b are displayed on the display screen 250. The model seek bar 259a is used to change the simulation site model 120 displayed on the display screen 250 to the simulation site model 120 at an arbitrary date and time. The appearance seek bar 259b is used to change the appearance data 130 displayed on the display screen 250 to the appearance data 130 at an arbitrary date and time.

[0050] The model seek bar 259a and the appearance seek bar 259b are not linked and move independently, meaning that the date and time of the simulation site model 120 and the date and time of the appearance data 130 can be changed separately.

[0051] Conversely, the model seek bar 259a and the appearance seek bar 259b may be designed to move in tandem. In other words, when one is moved, the other may also move in the same way. In this way, when the date and time of either the simulation site model 120 or the appearance data 130 is changed, the date and time of the other is also changed in tandem, making it even easier to compare the simulation site model 120 and the appearance data 130.

[0052] The display screen 250 may display a seek bar linkage switching button for switching between a state in which the model seek bar 259a and the appearance seek bar 259b are linked and a state in which they are not linked.

[0053] 2B , the display control unit 205 may also display information other than the simulation site model 120 and the appearance data 130 simultaneously with the simulation site model 120 and the appearance data 130. Specifically, at least one of construction information 251, equipment information 252, personnel information 253, work information 254, weather information 255, warning information 256, and environmental information 257 may also be displayed.

[0054] The construction information 251 is information about construction work being carried out at the construction site 110. Examples of the construction information 251 include the name of the construction work, the contractor for the construction work, the address of the construction site 110, the construction price, and the construction details.

[0055] The equipment information 252 is information about the equipment delivered to the construction site 110. Examples of the equipment information 252 include the name of the equipment, the total number of pieces of equipment, the number of pieces of equipment in operation, the operating hours of the operating equipment, the names of users of the operating equipment, and the number of pieces of equipment that are out of service.

[0056] The personnel information 253 is information about personnel working at the construction site 110. Examples of the personnel information 253 include the total number of personnel at the construction site 110, the number of personnel for each task being performed at the construction site 110, and the number of personnel for each company involved in the construction work.

[0057] The work information 254 is information about work to be performed at the construction site 110. Examples of the work information 254 include a work schedule for a specific date, such as a time specified when creating the simulation site model 120, the progress rate for each work process to be performed at the construction site 110, and the progress rate for all work to be performed at the construction site 110.

[0058] The weather information 255 includes, for example, the weather at the construction site 110, temperature, humidity, air pressure, sunrise time, sunset time, and the like.

[0059] The warning information 256 includes, for example, warnings and advisories regarding strong winds, thunderstorms, photochemical smog, heat stroke, and the like.

[0060] The environmental information 257 may include, for example, noise levels at the construction site 110, vibration measurements, PM2.5 measurements, PM10 measurements, wind direction, wind speed, CO2 emissions, and whether or not there are traffic restrictions around the construction site 110.

[0061] Next, another method in which the display control unit 205 displays the simulation site model 120 and the appearance data 130 will be described with reference to FIGS. 2C to 2F.

[0062] 2C, a model display section 261a and an appearance display section 262a are displayed as main display sections. The model display section 261a displays the simulation site model 120 as viewed obliquely. The appearance display section 262a displays the appearance data 130 as viewed obliquely of the actual construction site 110. A model list display section 261b is displayed to the left of the model display section 261a. An appearance list display section 262b is displayed to the right of the appearance display section 262a.

[0063] The model list display section 261b displays an image of the simulation site model 120 as viewed from a different viewpoint from that of the simulation site model 120 displayed in the model display section 261a. Specifically, the model list display section 261b displays, in order from the top, images of the simulation site model 120 as viewed from the front, right side, left side, and back.

[0064] Note that the model list display section 261b may display an image of the simulation site model 120 as viewed from a viewpoint different from the viewpoints described above. Furthermore, the number of images of the simulation site model 120 displayed in the model list display section 261b is not limited to four, and may be three or less, or five or more.

[0065] The appearance list display section 262b displays images of the appearance data 130 when the actual construction site 110 is viewed from a different viewpoint from the appearance data 130 displayed in the appearance display section 262a. Specifically, the appearance list display section 262b displays, from top to bottom, images of the appearance data 130 when the actual construction site 110 is viewed from the front, right side, left side, and back.

[0066] The appearance list display section 262b may display images of the appearance data 130 when the actual construction site 110 is viewed from a viewpoint different from the viewpoints described above. Furthermore, the number of images of the appearance data 130 displayed in the appearance list display section 262b is not limited to four, and may be three or less, or five or more.

[0067] The following description will be given taking the simulation site model 120, the model display section 261a, and the model list display section 261b as examples, but the same description also applies to the appearance data 130, the appearance display section 262a, and the appearance list display section 262b.

[0068] The model list display section displays a list of images of the simulation site model 120 that can be displayed in the model display section 261a. The image of the simulation site model 120 displayed in the model list display section 261b can be used as the simulation site model 120 displayed in the model display section 261a.

[0069] Specifically, when any of the images displayed in the model list display section 261b is clicked, the clicked image is displayed as the simulation site model 120 in the model display section 261a.

[0070] For example, when the top image of the images displayed in the model list display section 261b is clicked, the image of the simulation site model 120 as viewed from the front, which has been displayed at the top of the model list display section 261b until now, is displayed in the model display section 261a as the simulation site model 120. Then, the image of the simulation site model 120 as viewed obliquely, which has been displayed in the model display section 261a until now, is displayed at the top of the model list display section 261b.

[0071] In this way, by clicking on an image of the simulation site model 120 from the model list display section 261b that corresponds to a viewpoint that the user wishes to display in the model display section 261a, the image can be displayed in the model display section 261a as the simulation site model 120. In other words, the image from the viewpoint that the user wishes to observe in detail can be displayed in the model display section 261a, which is the main display section.

[0072] By displaying the simulation site model 120 and the appearance data 130 from multiple different viewpoints, it is possible to compare the simulation site model 120 and the appearance data 130 from each viewpoint at once, allowing for a more detailed comparison of the two.

[0073] In FIG. 2D, the simulation site model 120 and the appearance data 130 are displayed in chronological order, with different specified dates and times. For example, the simulation site model 120 for the current time, one week prior to the current time, and two weeks prior to the current time are displayed in the first time point model display section 271a, the second time point model display section 271b, and the third time point model display section 271c, respectively. Note that the simulation site models 120 displayed in the first to third time point model display sections 271a to 271c are not limited to those for the above-mentioned time points. Furthermore, the simulation site models 120 for two different time points may be displayed, or the simulation site models 120 for four or more different time points may be displayed.

[0074] The appearance data 130 is also displayed in chronological order, similar to the simulation site model 120. For example, the appearance data 130 for the current time, one week prior to the current time, and two weeks prior to the current time are displayed in the first time point appearance display section 272a, the second time point appearance display section 272b, and the third time point appearance display section 272c, respectively. Note that the appearance data 130 displayed in the first to third time point appearance display sections 272a to 272c are not limited to those for the above-mentioned time points. Furthermore, the appearance data 130 for two different time points may be displayed, or the appearance data 130 for four or more different time points may be displayed.

[0075] By displaying the simulation site model 120 and the exterior data 130 with different specified dates and times in chronological order, it is possible to easily grasp the transition of the construction status of the building site 110 over time. In addition, for example, after the construction is completed, it is also possible to verify and evaluate the merits of the construction plan and the actual construction work.

[0076] 2B to 2D, the display control unit 205 displays the appearance data 130 and the simulation site model 120 side by side, but the method of displaying the appearance data 130 and the simulation site model 120 is not limited to this. For example, the display control unit 205 may display the appearance data 130 and the simulation site model 120 overlapping or by switching between them.

[0077] In FIG. 2E, the appearance data 130 and the simulation site model 120 are displayed overlapping each other. The appearance data 130 and the simulation site model 120 are displayed in a manner that allows them to be distinguished from each other. Specifically, when they are overlapped, the data arranged on the top, i.e., the simulation site model 120, is transparent, and the data arranged on the bottom, i.e., the appearance data 130, is visible. Note that the overlapping order may be reversed. Furthermore, the appearance data 130 and the simulation site model 120 have the same size and viewpoint. By displaying the appearance data 130 and the simulation site model 120 overlapping each other, it becomes easier to understand whether there are any differences between them.

[0078] 2E also displays a viewpoint change controller 280 that can change the viewpoint of the image where the simulation site model 120 and the appearance data 130 are superimposed. Also displayed is a seek bar 281 that can change the date and time of the image where the simulation site model 120 and the appearance data 130 are superimposed.

[0079] In FIG. 2F, the appearance data 130 and the simulation site model 120 are alternately displayed. A changeover switch 290 is displayed on the display screen 250, and the changeover switch 290 is used to alternately display the appearance data 130 and the simulation site model 120. The appearance data 130 and the simulation site model 120 have the same size, viewpoint, and display position. By alternately displaying the appearance data 130 and the simulation site model 120, it becomes easier to determine whether there are any differences between them.

[0080] FIG. 3 is a diagram illustrating an example of a display position control table 301 included in the construction management device 100. The display position control table 301 stores basic information 312 and associated information 313 in association with a display method 311. The display method 311 is a method by which the display control unit 205 displays the simulation site model 120 and the appearance data 130, and includes settings such as parallel mode, superimposed mode, and switching mode. The basic information 312 indicates the display positions of the simulation site model 120 and the appearance data 130, i.e., the display positions on the display screen 250. The associated information 313 indicates the display positions of information other than the simulation site model 120 and the appearance data 130, such as construction information 251 and equipment information 252, i.e., the display positions on the display screen 250. The display control unit 205 references the display position control table 301 to display the simulation site model 120, the appearance data 130, and other information on the display 140.

[0081] The hardware configuration of the construction management device 100 will be described with reference to FIG. 4. The CPU (Central Processing Unit) 410 is a processor for arithmetic and control, and executes programs to realize the various functional components of the construction management device 100 shown in FIG. 2A. The CPU 410 may have multiple processors and execute different programs, modules, tasks, threads, etc. in parallel. The ROM (Read Only Memory) 420 stores fixed data such as initial data and programs, as well as other programs. The network interface 430 communicates with other devices via a network. The CPU 410 is not limited to a single CPU, and may include multiple CPUs or a GPU (Graphics Processing Unit) for image processing. The network interface 430 preferably has a CPU independent of the CPU 410 and writes and reads transmission / reception data 446 to and from an area of ​​the RAM (Random Access Memory) 440. It is also preferable to provide a DMAC (Direct Memory Access Controller) (not shown) for transferring data between the RAM 440 and storage 450. Furthermore, the CPU 410 processes the data after recognizing that the data has been received or transferred to the RAM 440. The CPU 410 also prepares the processing results in the RAM 440, and leaves the subsequent transmission or transfer to the network interface 430 or DMAC.

[0082] The RAM 440 is a random access memory used by the CPU 410 as a temporary storage work area. The RAM 440 has a storage area reserved for storing data necessary for implementing this embodiment. The survey data 441 is survey data obtained by surveying the terrain 111 and the building 112. The three-dimensional model data 442 is the three-dimensional model data 121 of the entire construction site 110 created by the three-dimensional model data creation unit 201.

[0084] The storage 450 stores a database, various parameters, or the following data or programs required to implement this embodiment. The storage 450 stores a display position control table 301. The display position control table 301 is a table that manages the relationship between the display method 311, basic information 312, and associated information 313 shown in FIG. 3.

[0085] The storage 450 further stores a three-dimensional model data creation module 451, a construction plan data acquisition module 452, a simulation site model generation module 453, an appearance data acquisition module 454, and a display control module 455. The three-dimensional model data creation module 451 is a module that creates the three-dimensional model data 121. The construction plan data acquisition module 452 is a module that acquires the construction plan data 160. The simulation site model generation module 453 is a module that generates the simulation site model 120. The appearance data acquisition module 454 is a module that acquires the appearance data 130. The display control module 455 is a module that displays the simulation site model 120 and the appearance data 130 on the display 140. These modules 451 to 455 are read into the application execution area 447 of the RAM 440 by the CPU 410 and executed. The control program 456 is a program for controlling the entire construction management device 100.

[0086] The input / output interface 460 interfaces input / output data with input / output devices. A display unit 461 and an operation unit 462 are connected to the input / output interface 460. A storage medium 464 may also be connected to the input / output interface 460. A speaker 463 serving as an audio output unit, a microphone (not shown) serving as an audio input unit, or a GPS position determination unit may also be connected. Note that the RAM 440 and storage 450 shown in FIG. 4 do not include programs or data related to the general-purpose functions of the construction management device 100 or other feasible functions.

[0087] Next, the processing procedure of the construction management device 100 will be described with reference to the flowchart shown in Fig. 5. This flowchart is executed by the CPU 410 in Fig. 4 using the RAM 440, and realizes each functional configuration of the construction management device 100 in Fig. 2A.

[0088] In step S501, the three-dimensional model data creation unit 201 acquires survey data of the terrain 111 and the building 112. In step S503, the three-dimensional model data creation unit 201 creates three-dimensional model data 121 based on the survey data. In step S505, the construction plan data acquisition unit 202 acquires the construction plan data 160.

In step S511, the display control unit 205 displays the simulation site model 120 and the appearance data 130 on the display 140.

[0089] According to this embodiment, construction management of a building can be performed. For example, the operator of the construction management device 100 can easily grasp the construction status of the construction site 110. Furthermore, the operator can grasp the progress of the construction work and consider whether or not changes to the construction plan are necessary without actually visiting the construction site 110.

[0090] [Second embodiment] Next, a construction management device 600 according to a second embodiment of the present invention will be described with reference to Figures 6A to 8. Figure 6A is a block diagram illustrating the configuration of the construction management device 600 according to this embodiment. The construction management device 600 according to this embodiment differs from the first embodiment in that it further includes a difference display control unit 601 and a reception unit 602. The other configurations and operations are the same as those in the first embodiment, so the same configurations and operations are denoted by the same reference numerals and detailed description thereof will be omitted.

[0091] The difference display control unit 601 compares the appearance data 130 and the simulation site model 120 and displays the difference 611. Here, with reference to FIG. 6B , an example will be described in which the difference display control unit 601 displays the difference 611 on the display screen 250. In FIG. 6B , both the difference 611 and parts where there are no differences between the appearance data 130 and the simulation site model 120 are displayed. The parts where there are no differences are the terrain 111, buildings 112, and construction machinery 133. The difference 611 is represented by a dashed line, and parts where there are no differences between the appearance data 130 and the simulation site model 120 are represented by a solid line. In this way, the difference 611 and parts where there are no differences are displayed in a manner that allows them to be distinguished from each other.

[0092] There are no particular limitations on the method for distinguishing between the difference 611 and the non-difference portion. For example, the difference 611 may be represented by a solid line, and the non-difference portion may be represented by a dashed line. Furthermore, the difference 611 and the non-difference portion may be represented by different degrees of transparency or colors.

[0093] Difference 611 is a portion where there is a difference in the external shape between exterior data 130 and simulation site model 120. In three-dimensional model 123 of the portion of simulation site model 120 where construction is scheduled to be completed, construction has been completed up to the third floor of building 150, whereas in exterior data 130, completed construction portion 134 is only the first floor of building 150. In other words, both the second and third floors of building 150 are difference 611. In other words, difference 611 is a difference in external shape that is manifested as the difference between the construction status of construction site 110 planned in construction plan data 160 and the actual construction status of construction site 110. Note that difference display control unit 601 may display only difference 611.

[0094] The reception unit 602 receives a change to the work process according to the difference 611. The operator of the construction management device 600 views the difference 611 displayed on the display screen 250 to determine, for example, whether there is a delay in the progress of the construction work. If there is a delay in the progress of the construction work, the operator considers, for example, whether it is necessary to change the work process to speed up the progress. Examples of changes to the work process include shortening the work period of a work process planned in the construction plan data 160, increasing the number of personnel performing the work process, changing the order in which the work process is performed, omitting the work process, and adding a work process that was not planned in the construction plan data 160. If it is necessary to change the work process, the operator inputs information after the change, such as the changed work period and the changed number of personnel, into a work process change box 621 on the display screen 250. The reception unit 602 receives the information entered in the work process change box 621.

[0095] The construction plan data 160 may be updated based on changes to the work process accepted by the accepting unit 602. For example, information entered in the work process change box 621 may be reflected in the construction plan data 160. Furthermore, based on the updated construction plan data 160, the construction status of the building site 110 at a specified time may be re-simulated, and the simulation site model 120 may be re-generated.

[0096] The hardware configuration of the construction management device 600 will be described with reference to Figure 7. The RAM 740 is a random access memory used by the CPU 410 as a temporary storage work area. The RAM 740 has a storage area reserved for storing data necessary for implementing this embodiment. The difference data 741 is data of the difference 611 between the appearance data 130 and the simulation site model 120. The change data 742 is data of the changed work process received by the reception unit 602.

[0097] The storage 750 stores a database, various parameters, or the following data or programs required to implement this embodiment. The storage 750 also stores a difference display control module 751 and a reception module 752. The difference display control module 751 is a module that compares the appearance data 130 and the simulation site model 120 and displays the differences 611. The reception module 752 is a module that receives changes to the work process in accordance with the differences 611. These modules 751 to 752 are read into the application execution area 447 of the RAM 740 by the CPU 410 and executed.

[0098] Next, the processing procedure of the construction management device 600 will be described with reference to the flowchart shown in Fig. 8. This flowchart is executed by the CPU 410 in Fig. 7 using the RAM 740, and realizes each functional configuration of the construction management device 600 in Fig. 6A.

[0099] In step S801, the difference display control unit 601 compares the appearance data 130 and the simulation site model 120 and displays the difference 611. In step S803, the receiving unit 602 receives a change to the work process according to the difference 611. The construction management device 600 may update the construction plan data 160 based on the change to the work process received by the receiving unit 602.

[0100] According to this embodiment, construction management of a building can be performed more easily. For example, the operator of the construction management device 600 can easily understand whether or not a difference 611 has occurred between the appearance data 130 and the simulation site model 120, and can easily understand whether the construction work is progressing according to the construction plan data 160. In addition, the construction plan data 160 can be flexibly changed in accordance with the difference 611. Furthermore, the simulation site model 120 can be regenerated taking the difference 611 into consideration.

[0101] Although the present invention has been described above with reference to the embodiments, the present invention is not limited to the above-described embodiments and can be modified as appropriate. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention within the scope of the present invention. Furthermore, systems or devices that combine separate features included in each embodiment in any manner are also included in the scope of the present invention.

[0102] The present invention may also be applied to a system consisting of multiple devices or to a single device. Furthermore, the present invention may also be applied when an information processing program that realizes the functions of the embodiments is supplied to a system or device and executed by a built-in processor. Therefore, the technical scope of the present invention also includes a program installed on a computer to realize the functions of the present invention, a medium storing the program, a WWW (World Wide Web) server from which the program is downloaded, and a processor that executes the program. In particular, the technical scope of the present invention also includes a non-transitory computer-readable medium storing a program that causes a computer to execute at least the processing steps included in the above-described embodiments.
