Description

  The present invention relates to an information processing technique for displaying a structure constructed by construction.

  In construction work such as civil engineering and architecture, various documents such as design documents such as design documents and blueprints and construction plan documents such as process schedules are created. Conventionally, a technique in which an apparatus supports the creation of such a document has been proposed. For example, a process chart creation support device that supports creation of a process chart in building work has been proposed (see Patent Document 1). There has also been proposed a construction process management program that can quickly and accurately create materials necessary for process planning and management (see Patent Document 2). In addition, a blueprint for construction may be created by CAD (Computer Aided Design). For example, an architectural design drawing creation program having a three-dimensional drawing function has been proposed (see Patent Document 3).

  Various documents such as design books and process charts created by such devices and programs are managed as independent documents. Those involved in the construction read the relationship between the information described in separate documents, depending on the terms and shapes of the figures described in each document.

The visualization device also visualizes the construction status that changes over time as a 3DCG animation of the structure. In addition, the construction status of the construction work may be visualized by the visualization device without being limited to the civil engineering work.

<Hardware configuration>
The visualization device is a computer and is operated by a user such as a construction worker who is involved in the construction. The visualization device is, for example, a personal computer. The visualization device may be a tablet terminal, a smartphone, a workstation, or the like.

  FIG. 1 is a diagram illustrating a hardware configuration of a visualization apparatus according to this embodiment. The visualization device 1 includes a CPU (Central Processing Unit) 11, a RAM (Random Access Memory) 12, a ROM (Read Only Memory) 13, an auxiliary storage device 14 such as a HDD (Hard Disk Drive), and a NIC (Network) connected to the Internet. (Interface Controller) 15, an operation unit 16 such as a keyboard and a pointing device, and a display unit 17 such as a display.

  The CPU 11 is a central processing unit, and controls the RAM 12, the auxiliary storage device 14, and the like by processing instructions and data expanded in the RAM 12 and the like. The RAM 12 is a main storage device and is controlled by the CPU 11 to write and read various commands and data. The auxiliary storage device 14 is a non-volatile storage device, and stores various programs, data required to be permanently saved, and the like. The auxiliary storage device 14 of the present embodiment also stores a visualization application that is an application program that processes the visualization of the construction status, and a process management application that is an application program that supports process management.

<Functional configuration>
FIG. 2 is a diagram illustrating a functional configuration of the visualization device 1 according to this embodiment. FIG. 2 illustrates main functions of the visualization device 1.

  The visualization device 1 is configured such that programs such as a visualization application and a process management application stored in the auxiliary storage device 14 are read into the RAM 12 and executed by the CPU 11, so that the construction database D 11, the plan acquisition unit F 11, the design acquisition unit It functions as a computer provided with F12, work performance acquisition part F13, and display data generation part F14. The plan acquisition unit F11, the design acquisition unit F12, the work result acquisition unit F13, and the display data generation unit F14 are respectively “plan acquisition unit”, “design acquisition unit”, “work result acquisition unit”, and “ This is an example of “display data generation means”.

  In this embodiment, each function provided in the visualization device 1 is executed by the CPU 11 that is a general-purpose processor. However, some or all of these functions are performed by one or more dedicated processors (for example, GPU (Graphics Processing). Unit)), and may be executed by a hardware arithmetic circuit or the like. Here, the hardware arithmetic circuit refers to, for example, an adder circuit, a multiplier circuit, a flip-flop, etc. combined with logic gates. Some or all of these functions may be executed by a separate computer connected via a network or the like.

The construction database D11 is a database that manages various data related to construction by storing them in the auxiliary storage device 14. Data managed in the construction database D11 is registered by a user input operation or the like. In the construction database D11, data relating to one construction may be managed, or data relating to a plurality of constructions may be managed. The construction database D11 includes a plan table, a design table, and an actual result table. The construction database D11 may be constructed in a separate database server different from the visualization apparatus 1 and accessed by the visualization apparatus 1 via a network.

  The plan table stores plan data including a scheduled period for each work item of the construction. The plan table is an example of a “plan storage unit”. The stored plan data indicates construction plan information that can be represented by a process chart or the like. The work item is an item obtained by subdividing the work contents. The work items of this embodiment are, in accordance with the construction work type system defined by the Ministry of Land, Infrastructure, Transport and Tourism, one work (systemized as "construction category") in order from the top "work type", "type", "subdivision" Are handled as being subdivided into three levels. In this embodiment, “detail” is the minimum unit of work items. Subdivision corresponds to the basic unit objects and unit temporary structures that constitute the construction. For example, river repair work is subdivided into a work type “river earthwork”, a type “excavator”, and a subdivision “excavation”. The work items may be handled in units obtained by further subdividing the subdivision. The scheduled period is a planned period in which work is performed, and is represented by a set of work start date and work end date in this embodiment.

  The design table stores design data indicating various designs of construction. The design table is an example of a “design storage unit”. The design data includes data indicating the shape and size of each structure constructed by the construction, the position and range of the construction site, and the like. The structure indicated by the design data is not limited to the object finally constructed in the construction, but includes a structure constructed temporarily. The design data includes data indicating a plan view overlooking the construction site by describing the position and range where the structure is constructed on the construction site map. The design data is taken from various design books and constructed. The design data is expressed in a data format used in CAD, for example. The design table can also store information indicating the relationship between the design data and the work item of the construction, and the design data that is the purpose of the work item in the construction can be associated with the work item.

The result table stores work result data indicating work results for the work items of the plan data. The result table is an example of a “work result storage unit”. The work performance data includes work end time data represented by a work end date or the like, and indicates whether or not the work item has been finished and information on the work end time. The work performance data may include a progress rate of work items.

  The plan acquisition unit F11 accesses the construction database D11 and acquires plan data from the plan table. The design acquisition unit F12 accesses the construction database D11 and acquires design data from the design table. The work result acquisition unit F13 accesses the construction database D11 and acquires work result data from the result table.

  The display data generation unit F14 is constructed by the drawing date or the structure scheduled to be built by the drawing date when the display request specifying the drawing date as the reference time point is received by the user operation. Display image data used to display a structure with a proven track record. The display data generation unit F14 of the present embodiment generates image data by drawing the shape of the structure with 3DCG. In the present embodiment, the reference time point is processed as a drawing date in units of one day, but the reference time point may be processed using a finer unit such as half a day, one hour, or one minute.

<Operation flow>
The main processing flow of the visualization apparatus 1 of this embodiment will be described. Note that the contents and order of the operations to be described are examples, and it is preferable that the contents and order of the operations are appropriately selected according to the embodiment.

(Data registration for construction)
FIG. 3 is a flowchart illustrating the flow of data registration regarding construction. This flow is realized when the user activates the process management application or the visualization application of the visualization apparatus 1 and performs an interactive input operation. With this flow, various data relating to the work to be visualized is registered in the work database D11. Note that data registered by a separate computer different from the visualization device 1 may be copied to the visualization device 1 and registered.

  In step S101, a construction management plan is created. The process management application of the visualization device 1 accepts a work item data input operation as a work content related to a specific work, and stores and registers the input work item data as plan data in the plan table of the construction database D11. . In the present embodiment, work item data is input using a construction content registration screen and a process management screen.

  FIG. 4 is a diagram illustrating a construction content registration screen. In the construction content registration screen SC1 of FIG. 4, work items are shown in a table format. The work name of the work item (column SC11), the unit (column SC12) indicating the work amount of the work item, and the quantity (column SC13). ) Is entered in each field. Each line in the display indicates a work item. The work item is input with data using the operation unit 16 such as a keyboard or a pointing device. It should be noted that separately created data may be imported via the Internet, removable media, etc., and input as work item data by an integration system of an ordering organization for public works.

FIG. 5 is a diagram illustrating a process management screen. In the process management screen SC2 of FIG. 5, a scheduled period represented by a set of a work start date and a work end date is input for each work item. As shown in FIG. 5, the scheduled period is displayed as a process chart in the form of a bar chart. The scheduled period is input by, for example, inputting characters with a keyboard or dragging a bar chart area with a pointing device. Note that data of a scheduled period created separately may be imported. Further, the scheduled period may be represented by a set of the work start date and the number of work days, or may be represented by a finer unit such as a half day or one hour instead of a day unit. In the present embodiment, the scheduled period is shown in the form of a bar chart, but it may be displayed in a network diagram or other form.

  In addition, it is also possible to input work results for each work item using the process management screen SC2. The work results are appropriately input by the construction manager or the like after the start of construction and used for construction management. For example, when a work end date for a work item is input, work result data indicating that the work for the work item has been completed is added to the result table of the construction database D11 and registered. The For example, a progress rate, which is a numerical value indicating the rate of work performance expressed in percentage, may be input to each work item every day. In this case, when the progress rate is input, the date of the input is regarded as the day when the input progress rate is reached, and work result data indicating that the work item has reached the progress rate on the date May be registered. When a progress rate of 100% is input for a work item, work result data indicating that the work item has been completed is registered on the day of input.

  In step S102, the visualization application captures design data from the design book. The visualization application receives designation of a CAD data file or the like representing a target design book or plural design books from the user, and starts the capturing process. The visualization application reads the data of the designated design book and registers it as design data in the design table of the construction database D11. The registered design data will be associated with the work item later. The design data includes various design drawings such as a plan view and a sectional view showing the shape of the structure constructed by the construction, a map including the construction site, and the like. The imported design books may be expressed in data formats other than CAD, such as tabular data and text data.

  In step S103, the visualization application accepts a user operation specifying the work position and range of the work item, and the design indicates the position and range of the work item, that is, the position and range where the target structure of the work item is constructed. Associate data with work items. First, the visualization application accepts a user operation for specifying the work position and range of the work item using the work position setting screen.

  FIG. 6 is a diagram illustrating a work position setting screen. On the work position setting screen SC3, a plan view in which a figure showing each structure is arranged on a map showing the construction site is displayed. The plan view is a bird's-eye view of the construction site, and allows an overview of the construction area including the structure to be constructed. The user selects a figure boundary line indicating the structure using the operation unit 16 such as a pointing device, and the structure constructed by the work items to be associated from the structures shown in the plan view. Specify the position and range of the. At the time of designation, the plan view may be appropriately enlarged according to the user's operation.

  Next, the visualization application receives a user operation for specifying a work item. For example, the visualization application refers to the plan table of the construction database D11, displays the work names of the stored work items in a tree format according to the hierarchy, and accepts the designation of the work items according to the user's selection operation. Next, the visualization application associates the design data indicating the position and range of the designated structure by adding information indicating the relationship between the designated work items to the design table of the construction database D11.

  The operation in step S103 is repeatedly performed for all work items that the user desires to visualize, and each target work item is associated with design data indicating the position and range of the structure constructed by each work item. .

In step S104, the visualization application further associates the design data indicating the shape and size of the structure constructed by the work item with the work item. First, the visualization application receives an operation for specifying a work item to be associated from a user. Next, the visualization application receives a design data designation operation via the structure shape setting screen.

  FIG. 7 is a diagram illustrating a structure shape setting screen. On the structure shape setting screen SC4, any of the design books taken in step S102 is displayed according to the user's selection. In FIG. 7, a design book including a developed view SC41 and a sectional view SC42 is displayed. When the user specifies a figure that shows the shape or size of the structure constructed by the work item to be associated from the displayed design document, the visualization application will display the design that shows the specified figure. Identify the data. The visualization application adds information indicating the relationship between the specified design data and the designated work item to the design table of the construction database D11, and associates the design data with the work item. Here, a plurality of drawings (for example, the developed view SC41 and the sectional view SC42 in FIG. 7) and the like constituting the three-dimensional shape of the structure are designated for one work item, and the design data is associated therewith. And the data which prescribes | regulates the three-dimensional shape and magnitude | size of a structure are constructed | assembled in the construction database D11 by taking the correspondence of the design data which shows each designated figure.

  The operation in step S104 is repeatedly performed for all work items that the user desires to visualize, and each of the target work items is associated with each of the design data captured from various design books.

  By such data registration operation related to construction, data necessary for visualization processing described later is registered in the construction database D11. In this embodiment, various types of data are registered and associated by a user's manual operation. However, the visualization application is drawn on the design drawing of the design book based on the character string included in the taken design book. The data may be automatically registered by determining the structure, the type of figure, the relationship with the work item, and the like.

(Visualization process)
FIG. 8 is a flowchart illustrating the flow of a construction status visualization process. This processing flow starts when the visualization application is activated and a user operation for selecting a construction status visualization function from the menu is accepted. The visualization application visualizes the construction status of one selected construction according to the user's selection of construction to be visualized. This processing flow is based on the premise that the data registration flow related to the above-described construction has been completed.

  In step S <b> 201, the visualization device 1 receives an operation for specifying a work item to be visualized from a user. In the present embodiment, the visualization apparatus 1 displays a list of work items in the construction to be visualized based on the plan data stored in the plan table of the construction database D11, and accepts an operation for specifying the work item to be visualized. . Here, for example, the work items are displayed as a list in a tree format according to the construction work type system by the name of the work type, type, and subdivision. The user can designate one work item as a visualization target by selecting the subdivision of the lowest layer. In addition, the user can collectively specify a plurality of work items indicating subdivisions under the item by selecting an item in an upper layer such as a work type or a type. By specifying the work item to be visualized in this way, the user can visualize the construction status by focusing on the construction by the desired work item.

  In step S202, the visualization apparatus 1 accepts a drawing date designation operation from the user via the drawing range setting dialog. The visualization apparatus 1 also receives instructions for various display methods from the drawing range setting dialog.

  FIG. 9 is a diagram illustrating a drawing range setting dialog. The drawing range setting dialog SC5 includes a slider SC51 that is a GUI (Graphical User Interface) part for designating a drawing date. Here, the drawing date represents a “reference time point” for distinguishing the objects to be visualized in units of days. By the moving operation of the slider SC51, a value between the work start date and the work work end date in the work to be visualized can be designated as the drawing date. In FIG. 9, December 16, 2013 is designated as the drawing date.

  The drawing range setting dialog SC5 also includes a volume color display check box SC52, a volume limit display check box SC53, a playback button SC54, and a drawing execution button SC55 as GUI components. The output color display check box SC52 is a check box with a label of “display the output in color”, and displays a structure constructed by a proven work item in a special color scheme. Used to request The volume limit display check box SC53 is a check box with a label of “display only the volume completed part” and has a track record without displaying a structure constructed by a scheduled work item. Used to request that only structures built with work items are displayed. The reproduction button SC54 is a button for requesting continuous visualization of the construction status after the drawing date. The drawing execution button SC55 is a button for requesting to draw a structure or the like and visualize the construction status on the drawing date.

  In step S203, the display data generation unit F14 of the visualization device 1 accepts a pressing operation of the reproduction button SC54 or the drawing execution button SC55 from the user. The pressing operation is an example of “display request”. The pressing of the play button SC54 is an example of “request for continuous display”.

  In step S204, the visualization apparatus 1 draws a structure or the like in order to visualize the construction status on the drawing date. Specifically, when the visualization device 1 specifies a drawing date and starts a drawing process, image data for display is generated, and a visualization screen including the generated image data is displayed on the display device 17 and applied. The situation is visualized. The drawing date specified here is in accordance with the specifying operation accepted in step S202. Details of the drawing processing for structures and the like will be described later. Step S204 is an example of a “display data generation step”.

  FIG. 10 is a diagram illustrating a visualization screen. On the visualization screen SC6, a structure constructed with work items scheduled to be completed by the drawing date, a structure constructed with work items with a track record completed by the drawing date, and the like are rendered in 3DCG. The 3DCG such as a structure is drawn according to the viewpoint and line of sight specified by the user. The visualization screen SC6 also includes a side bar SC61 that is a GUI component for performing display settings and the like.

  In step S205, the display data generation unit F14 determines whether or not subsequent drawing is necessary. When the display data generation unit F14 is requested to continuously visualize by pressing the play button SC54 in step S203, and the current value of the drawing date is before the construction end date, It is determined that subsequent drawing is required. If it is determined that subsequent drawing is required, the process proceeds to step S206 (S205; Yes). If it is not determined that the subsequent drawing is required, the flow of the construction status visualization process ends (S205; No).

  In step S206, the display data generation unit F14 advances the drawing date by a predetermined time (for example, one day). The drawing date is updated to a date after a predetermined time. Here, the predetermined time as the amount by which the drawing date is advanced can be changed and set by the user.

After step S206, the process returns to step S204. In step S204, the drawing date advanced in step S206 is specified, the drawing process is started again, and a new visualization screen SC6 is displayed. By repeatedly executing the processes of steps S204 to S206, images in which the construction status of each drawing date is visualized are sequentially displayed while the drawing date continuously changes in the later direction. The construction status that changes with time will be displayed as a moving image.

  Note that the user can change the 3DCG viewpoint and line of sight of the visualization screen SC6 by operation. By updating and displaying the visualized image while continuously changing the viewpoint and line of sight, it is possible to realize a so-called walk-through video as if walking around the virtual space of the construction site expressed in 3DCG. In addition, by changing the viewpoint and line of sight, it is possible to obtain a display such as an aerial photograph looking down at the construction site from the sky.

(Drawing process for structures, etc.)
FIG. 11 is a flowchart illustrating the flow of a drawing process for a structure or the like. The flow of this process shows the details of the process of step S204 in FIG. This processing flow is started after a drawing date is designated. Note that execution of the following steps S301 to S311 is completed instantaneously (for example, within several tens of milliseconds).

  In step S301, the display data generation unit F14 of the visualization device 1 determines whether there is a display request related to the schedule. The display data generation unit F14 confirms whether or not the volume limited display check box SC53 of the drawing range setting dialog SC5 is checked, and determines that there is a display request related to the schedule when there is no check. In this case, the process proceeds to step S302 (S301; Yes). On the other hand, when the volume-limited display check box SC53 is checked, the display data generation unit F14 determines that only the display request related to the performance is set, and determines that there is no display request related to the schedule. In this case, the process proceeds to step S304 (S301; No).

  In steps S302 to S303, a set of design data of structures to be built by the designated drawing date is acquired.

  First, in step S302, the display data generation unit F14 extracts work items scheduled to be completed by the designated drawing date from the plan data in the plan table of the construction database D11 via the plan acquisition unit F11. Specifically, among the work items included in the plan data, it is designated as a work item to be visualized (see step 201 in FIG. 8), and the work end date or drawing date is the same as the drawing date. A work item having a previous work end date is extracted.

  Next, in step S303, the display data generation unit F14 collects a set of design data associated with each work item extracted in step S302 from the design table of the construction database D11 via the design acquisition unit F12. get. The set of design data acquired here indicates the shape, size, position, etc., of each structure constructed with the scheduled work items up to the drawing date.

  In step S304, the display data generation unit F14 determines whether or not there is a display request related to the results. At this time, the display data generation unit F14 refers to whether or not the volume color display check box SC52 is checked in the drawing range setting dialog SC5 and whether or not the volume limit display check box SC53 is checked. The display data generation unit F14 determines that there is a display request related to the performance when any check box is checked. In this case, the process proceeds to step S305 (S304; Yes). On the other hand, the display data generation unit F14 determines that there is no display request related to the results when none of the check boxes are checked. In this case, the process proceeds to step S308 (S304; No).

  In steps S305 to S306, a set of design data of structures having a construction record by the designated drawing date is acquired.

  First, in step S305, the display data generation unit F14 extracts work items that have been completed by the designated drawing date from the work result data acquired through the work result acquisition unit F13. In the present embodiment, work items having the same work end date as the drawing date or an execution end date before the drawing date are extracted from the work items in the performance table of the construction database D11.

  In step S306, the display data generation unit F14 collects a set of design data associated with each of the work items extracted in step S305 from the design table of the construction database D11 via the design acquisition unit F12. get. The set of design data acquired here indicates the shape, size, position, etc., of each structure constructed with work items that have a track record by the drawing date.

  In step S <b> 307, the display data generation unit F <b> 14 excludes the design data of the structure acquired in duplicate. First, the display data generation unit F14 overlaps between the design data set of the structure to be built acquired in step S303 and the design data set of the proven structure acquired in step S306. It is determined whether or not the design data of the structure to be present exists. Next, when there are duplicate design data in both sets, the display data generation unit F14 excludes the design data of the duplicate structure from the set of design data of the structure constructed by the scheduled work item. To do. In the present embodiment, such an exclusion process is performed in order to avoid drawing a duplicate structure and preferentially draw a structure constructed with a work item with a track record.

  In steps S308 to S309, rendering data used for rendering that represents an object such as a structure in computer graphics is generated.

  First, in step S308, the display data generation unit F14 generates plane rendering data representing the ground surface. Specifically, the display data generation unit F14 obtains a plan view that describes the position and range where each structure is constructed on the construction site map from the design table of the construction database D11 via the design acquisition unit F12. Then, rendering data representing a three-dimensional model of a plane obtained by pasting the image of the plan view on the surface at an appropriate scale is generated.

  In step S309, the display data generation unit F14 generates the rendering data of the structure constructed by the construction from the set of the structure design data acquired in steps S303 and S306. Specifically, the display data generation unit F14 represents a three-dimensional model of the structure based on information such as the three-dimensional shape, size, material, and position of each structure included in the acquired set of design data. Generate data for rendering. At this time, processing such as derivation of colors from the material, conversion and correction of coordinate values, and the like are performed.

  The three-dimensional model of the rendering data structure generated here has a position, size, and direction in the virtual space to be rendered according to the position, size, and direction of the plane representing the ground surface. Adjusted and arranged. Specifically, when a three-dimensional model of a structure is orthogonally projected onto a three-dimensional model of a plane representing the ground surface, the position and range of the orthographic figure are pasted on the plane. The arrangement is adjusted so as to coincide with the position and range where the structure is constructed on the plan view. Here, the orthographically projected figure is a figure drawn by a trajectory of a perpendicular foot drawn from each point on the shape of the structure to the plane. The three-dimensional model of the structure is adjusted in the height direction so that the plane is at the height of the ground surface.

  Further, when the output color display check box SC52 of the drawing range setting dialog SC5 is checked, the display data generation unit F14 is for rendering generated from the set of design data of the proven structure acquired in step S306. A predetermined color (for example, red) indicating the actual result is set in the data. By doing in this way, the display color of a planned structure and the display color of a structure with a track record are produced, and the display which can distinguish both a plan and a track record can be provided to a user.

  The generated rendering data may be set with a color scheme or transparency specified by the user. In addition, in the generated rendering data, a texture mapping image for giving a texture to the surface of the three-dimensional model may be set according to the material of the design data.

  In step S310, the display data generation unit F14 executes rendering processing to generate display image data (an example of “display data”). The display data generation unit F14 performs a rendering process based on the rendering data generated in steps S308 and S309, the set line of sight, light source data, and the like. Specifically, the display data generation unit F14 generates image data obtained by projecting a three-dimensional model onto a field of view (also referred to as a screen or a projection surface) indicating a field of view. In the present embodiment, projection is performed according to a perspective projection method. At this time, the display data generation unit F14 performs various processes such as a hidden surface process such as a Z buffer method and a scan line method, a shadow process, and texture mapping. In the present embodiment, the display data generation unit F14 expresses each surface of the outer shape of the structure using a polygon, but expresses the surface by a wire frame method or the like that represents a set of line segments, Image data representing the outline boundary line may be generated.

  Further, the display data generation unit F14 of the present embodiment may generate image data including an image representing the sky, the ground, the coordinate axes, and the like according to the display setting. Further, the display data generation unit F14 according to the present embodiment may generate image data including a character string representing a design value or an actual measurement value of the size of the structure according to the drawing setting.

  In the present embodiment, the shape of the structure constructed with a proven work item is rendered based on the design data. However, when the measurement value of the constructed structure is recorded, the measurement is performed. A shape based on the value may be a rendering target. In addition, when the above-described plan view has the height information represented by contour lines or the like, the display data generation unit F14 represents the topography according to the height information instead of the plane representing the ground surface. A dimensional shape model may be rendered. By doing in this way, the construction situation of a construction site can be expressed more faithfully and more accurate visualization can be performed.

  In step S311, the visualization device 1 draws the display image data generated in step S310 on the visualization screen SC6 and causes the display device 17 to display the image data. The visualization device 1 may output the display image data as a file in a predetermined format to a removable medium such as a CD-R or DVD-R, the auxiliary storage device 14, or a printer for printing on paper. May be output. The display data generation unit F14 may generate two pieces of image data with parallax, and the image data may be output to a three-dimensional display and displayed in a stereoscopic manner. In addition, the visualization apparatus 1 includes a 3D printer that forms an object based on information about a three-dimensional shape, and forms a model of the structure on the 3D printer based on design data such as a structure to be built by the drawing date. You may let them. Thus, by performing printing, file output, modeling of the model, etc., the user can appropriately grasp the construction status using a desired display method.

<Effect>
In the present embodiment described above, when the drawing execution button SC55 is pressed, a display image representing the shape of the structure constructed by the drawing date based on the plan data and the design data in 3DCG. Data was generated instantaneously and displayed on the visualization screen SC6. Therefore, the construction status on the desired date is visualized and provided quickly as a specific display of the shape of the structure to be constructed. Thus, the user can easily and quickly grasp the construction status at each point in the construction. The specific display of the shape of the structure is easy to understand, even if it is not a person involved in the construction or an expert who is familiar with the construction, unlike the design drawings. For example, the visualization screen SC6 can be used as a material for priorizing the impact of construction on residents near the construction site. In addition, the visualization screen SC6 can be used as effective data for a construction person to quickly grasp the construction status.

  Further, in this embodiment, when pressing of the reproduction button SC54 is accepted, image data visualizing the construction status is sequentially generated according to the continuously changing drawing date, and continuously displayed on the visualization screen SC6. It was. Since the status of the construction of the structure is displayed in time series, the user can easily grasp the change over time in the construction status of the construction. In the present embodiment, the construction status is expressed as 3DCG of the structure in consideration of the date to be visualized. In the present embodiment, it can be said that the construction situation is visualized by a four-dimensional expression considering a time series in addition to a three-dimensional space expression.

  In the present embodiment, image data representing both a plane representing the ground surface on which a map of the construction site is drawn and a three-dimensional shape of the structure whose arrangement is adjusted with respect to the plane is generated and visualized. Displayed on screen SC6. Therefore, since the position and range which a structure occupies in a construction site with the shape of a structure are also visualized on a single screen, a more detailed construction situation can be grasped more easily. In addition, since the map is drawn on a plane, the structure is shown as a three-dimensional structure. Therefore, it is easy to identify the structure to be built, and it is possible to visualize a more favorable construction situation.

  In this embodiment, in addition to the shape of the structure to be constructed, image data indicating the shape of a structure with a track record built by the drawing date based on the work track record data is generated and displayed. Therefore, the construction status at each point in the construction can be visualized according to the results. Moreover, the visualization of the suitable construction condition which can grasp | ascertain the structure with a construction plan and the structure with construction results simultaneously is implement | achieved.

<Modification>
(Modification 1: Visualization by two-dimensional representation)
In the visualization of the above-described embodiment, the construction situation at each time point is expressed as 3DCG of the structure. The construction status at each time point may be expressed as a two-dimensional image indicating the position and range of the structure to be constructed. Such a modified example 1 will be described focusing on differences from the above-described embodiment.

  In the first modification, a visualization screen different from the visualization screen SC6 displayed in step S204 of FIG. 8 described above is displayed.

FIG. 12 is a diagram illustrating a visualization screen based on a two-dimensional expression in the first modification. On the visualization screen SC6A, a structure or the like constructed with work items scheduled to be completed by the drawing date is drawn as a plan view. On the visualization screen SC6A, an image in which a figure representing the position and range occupied by each structure on the map is displayed on the construction site map is displayed. In FIG. 12, an S-shaped graphic SC6AF1 represents the position and range on the map occupied by a structure constructed with work items scheduled to be completed by the drawing date. The figure SC6AF1 shows the upper surface shape of the structure, and its boundary line is represented by a line width thicker than the surrounding figure, and is colored according to the material of the structure. The portion of the visualization screen SC6A excluding the figure SC6AF1 is expressed using white or the like without being colored. In the visualization screen SC6A of the first modification, the structure constructed with the work items scheduled to be completed by the drawing date is displayed with the line width and the color highlighted as described above.

  Such a rendering process of the visualization screen SC6A is partially different from the rendering process described with reference to FIG. In the first modification, data indicating the three-dimensional shape of the structure is not processed in the design data, but only data indicating the upper surface of the structure is processed instead. In the first modification, the rendering of the three-dimensional model is not processed, and two-dimensional image processing is performed.

  In the first modification, image data is generated that highlights the position and range occupied by the structure constructed by the drawing date on the map including the construction site, and is displayed on the visualization screen SC6A showing the plan view. It was. In the first modification, the construction status is visualized by a two-dimensional image that is simple and easy to see, and the practical construction status can be visualized with less calculation resources by suppressing the consumption of memory and calculation time. it can.

(Variation 2: Visualization using construction photographs)
The construction status may be visualized using a construction photograph in addition to the shape of the structure. Such a modified example 2 will be described focusing on differences from the above-described embodiment.

  The construction database D11 of Modification 2 further includes a construction photo table (an example of “construction photo storage means”) that stores construction photo data indicating construction photos. A construction photo is a photograph taken at a construction site for the purpose of recording the construction status. For example, a construction management photo or a construction management photo showing the management status of the finished product, which is the part that has been constructed. It is a construction status photograph, a completed photograph, a safety management photograph, a quality control photograph, etc. showing the method. The construction photograph data is image data that shows a construction photograph taken with a digital camera or the like at a construction site in a predetermined data format. In the second modification, construction photo data collected from construction personnel and the like is stored in the construction photo table. The construction photo data is stored in the construction photo table in association with the work item of the construction and the shooting date and time. The work item associated here is a work item closely related to the construction situation shown in the construction photograph. For example, the construction photo data of the completed shape management photograph is associated with the work item indicating the construction of the completed shape that is copied to the completed shape management photo.

  The visualization device 1 of Modification 2 functions as a computer that further includes a construction photo acquisition unit (an example of “construction photo acquisition means”). The construction photo acquisition unit acquires construction photo data from the construction photo table of the construction database D11.

  The display data generation unit F14 of Modification 2 generates display image data including a construction photograph indicated by the construction photograph data in addition to the image of the structure drawn by 3DCG. Specifically, first, the display data generation unit F14 refers to the work item completed by the drawing date extracted based on the work performance data (see the process of step S305 in FIG. 11), and the work item. The construction photograph data associated with is extracted, and the associated photography date is before the drawing date. The display data generation unit F14 includes the construction photo of the extracted construction photo data in the display image data. For example, the construction photograph included here is superimposed on the displayed visualization screen with the position and scale adjusted on the image showing the shape of the structure so as not to overlap the region representing the shape. Further, when a plurality of construction photographs are extracted, the positions and scales of the plurality of construction photographs are adjusted so as not to overlap each other. On the visualization screen, a balloon-shaped figure may be drawn so as to surround the construction photo, and the balloon may protrude toward a region indicating the shape of a structure that is strongly related to the construction photo.

According to the second modification, the construction situation on each drawing date can be visualized using construction photographs, and the detailed construction situation including a record of the actual situation on site can be easily grasped. It becomes possible. In the modified example 2, the construction photograph as a still image taken at the construction site is included in the display image data, but the moving picture taken at the construction site is included in the display image data, and the visualization screen is displayed. May be displayed as a video. At this time, the voice recorded at the construction site may also be reproduced.

(Variation 3: Cloud-type visualization)
In the above-described embodiment, the visualization device 1 receives a display request in the form of a pressing operation such as the playback button SC54 from the user, and displays the visualization screen SC6 that visualizes the construction status on the display device 17 of the visualization device 1. The visualization device 1 receives a display request from the user's terminal connected to the Internet via the Internet, generates image data that visualizes the construction status of the drawing date according to the display request, and transmits the image data to the requesting terminal. May be. In this case, the user terminal receives the image data and displays it. In this case, the visualization device 1 serves as a server that provides an image that visualizes the construction status, and a cloud-type service is provided. Therefore, it is possible to suppress the processing load on the user's terminal, and it is possible to provide an image showing the construction status visualized with the clear 3DCG even in a terminal that does not have high image processing performance.
