A technique (for example, Patent Document 2) used as information is known.

  In addition, as a technique for utilizing three-dimensional data by laser measurement, three-dimensional data by fixed (non-moving) ground-type laser measurement, for example, three-dimensional data by a non-moving ground-type three-dimensional laser scanner is used. A technique for measuring the appearance and internal structure of a building and using a three-dimensional image of the building for a building plan is known (for example, Patent Document 3).

Specifically, when the input unit 31 of the terminal device 3 selects (inputs) a range in which a dimension is to be calculated from the structure 51 and the terrain in the three-dimensional map image displayed on the display unit 32. The size is calculated based on the point cloud data, and the calculation result is displayed on the display unit 32. Note that the calculation of the dimensions is not limited to the one displayed on the display unit as a three-dimensional map image, and the dimensions related to the three-dimensional object (terrain or structure) having the three-dimensional data stored in the storage unit 10 are calculated. Can do.

  The display selection means 36 makes it possible to select part or all of the structure 31 in the three-dimensional map image displayed on the display unit 32 so as to be in a display state or a non-display state. Specifically, a part or all of the structure 51 in the three-dimensional map image is selected by the input unit 31 of the terminal device 3, and the non-display is instructed to be input by the input unit 31. Can be hidden in the display section 32. In addition, by inputting an instruction to display the structure 51 in the non-display state by the input unit 31, the structure 51 in the non-display state can be displayed again. Note that not only the structure 51 but also a part or all of the terrain can be selected to be in a display state or a non-display state.

  The composite image generating unit 37 is configured to cause the display unit 32 to display a display image based on CAD data or polygon data included in the terminal device 3 on the three-dimensional map image displayed by the hierarchical map image display unit 26. As such CAD data and polygon data, three-dimensional CAD data stored in the terminal storage unit 33 can be used. The composite image generation unit 37 can be used in combination with the display selection unit 36. Specifically, a part of the structure 51 of the three-dimensional map image in the display unit 32 is set in a non-display state by the display selection unit 36, and the portion that is set in the non-display state by the composite image generation unit 37 is converted into CAD data. Display images can be displayed in a superimposed manner.

  The function classification creating unit 38 classifies the structures 51 included in the three-dimensional data in the storage unit 10 by the input unit 31 for each function, and stores the classified information in the storage unit 10 of the server 2. As the function classification, for example, a classification arbitrarily set by the user using the input means 31 such as a classification of piping or a function of equipment, or a classification registered in advance in the storage unit 10 of the server 2 can be performed.

  The function-specific display means 39 displays the structure 51 constituting the steel manufacturing plant 50 on the display unit 32 so as to be visually identifiable for each function. Specifically, regarding the function classification set in the storage unit 10 of the server 2, when a function division instruction is given from the input unit 31 of the terminal device 3, the structure 51 having the instructed function is represented by color. It is displayed on the display unit 32 so as to be distinguishable from other structures 51. For example, in the three-dimensional map image of the structure 51 displayed on the display unit 32, when the input unit 31 instructs the piping through which water (liquid) circulates and the piping through which steam circulates, The pipes with different functions can be visually identified by displaying the pipes in red and the steam pipes in yellow.

  The function-specific display means 39 can display the structure 51 having the same function in the same color in the three-dimensional map images having different scales. For example, the map display unit 21 displays two three-dimensional map images having different scales on the display unit 32, and in each three-dimensional map image, the structure 51 having the same function is displayed in the same color, thereby the same. Macro management and micro management of the structure 51 having a function can be performed in parallel.

  The visual identification display on the function-specific display means 39 is not limited to color identification display. For example, the structure 51 having the instructed function may be displayed in a blinking manner, or any other method that can be visually distinguished from the structure 51 having another function.

  In the above-described 3D image display system, display / non-display of the structure 51 or the like is selected by the display selection unit 36, and the display image of CAD data or polygon data is superimposed on the 3D map image by the composite image generation unit 37. By combining them, it is possible to simulate the design of the steel plant 50 and the repair work. Moreover, since the terrain and the dimensions of the structure 51 can be easily calculated by the dimension calculating means 35, the efficiency of the design work can be improved. Further, by generating a three-dimensional map image using point cloud data, CAD data can be overlaid on a wide area map information including the land area 61 and the sea area 62, so that the entire steel manufacturing plant 50 including the sea area 62 can be overlapped. It is also suitable for topographic management.

  In addition, since the function-specific display means 39 can display an image so that the facilities of the steelmaking plant 50 can be identified for each function, when the repair work is performed, there is a possibility that the effect of the repair may occur. Can be visually recognized before renovation work. Thereby, generation | occurrence | production of the malfunction in repair work can be avoided and the efficiency of repair work can be aimed at. Further, when the structure 51 is classified according to the level of danger, the function-specific display means 39 displays the structure 51 with a high degree of risk, which is used to prevent accidents in renovation work. be able to. In addition, by displaying the structure 51 with a low risk level, it can be used for securing an evacuation site.

  Note that the control unit 20 of the server 2 can be configured to transmit user interface elements that execute each unit in the terminal control unit 34 to the terminal device 3 so as to be displayed on the display unit 32 of the terminal device 3. For example, when the terminal device 3 is accessed from the terminal device 3 via the network 4, the control unit 20 of the server 2 displays a user interface element that causes the dimension measuring unit 35 to function on the display unit 32 of the terminal device 3. Thus, the terminal device 3 can be made to be able to execute the dimension measuring means 35. The display selection unit 36, the composite image generation unit 37, the function classification generation unit 38, and the function-specific display unit 39 can also have the same configuration.

  Next, the display process of the three-dimensional map image in the three-dimensional image display system 1 of the steel plant 50 described above will be described. FIG. 2 is a flowchart of the operation of the control unit 20 in the display process of the three-dimensional map image.

  First, a map display instruction of a three-dimensional map image from a user is received by the input means 31 of the terminal device 3 and when this map display instruction is received by the server 2 via the network 4 (step S100), the server 2 The map display means 21 determines whether or not the position designation relating to the map display is included in the map display instruction (step S101).

  When the position designation is not included in the map display instruction (step S101: No), the storage unit selection unit 25 selects the first storage unit 11 which is a preset storage unit. The hierarchical map image display means 26 generates a three-dimensional map image of a predetermined area set in advance from the three-dimensional data in the first storage means 11 and displays the three-dimensional map image on the display unit 32 of the terminal device 3. Is transmitted to the terminal device 3 (step S102), and the display process is terminated.

  When the location designation is included in the map display instruction (step S101: Yes), the storage unit selection unit 25 of the control unit 20 determines whether or not the scale designation is included in the map display instruction from the terminal device 3 (step S101). S103).

  When the map display instruction does not include the scale designation (step S103: No), the storage unit selection unit 25 selects the first storage unit 11 which is a preset storage unit. The hierarchical map image display means 26 generates a three-dimensional map image of a predetermined range area including the position designated by the terminal device 3 from the three-dimensional data of the first storage means 11, and the three-dimensional map image is displayed on the terminal device 3. Is transmitted to the terminal device 3 so as to be displayed on the display unit 32 (step S104), and the display process is terminated.

  When the map display instruction includes the scale designation (step S103: Yes), the storage unit selection unit 25 extracts the storage unit including the three-dimensional data at the specified position, and is designated from the extracted storage unit. One storage unit suitable for the scale is selected (step S105) (storage unit selection step). When the selected storage means is the third storage means 13, the storage unit selection means 25 is further designated from among the first narrow area data storage means 16 and the second narrow area data storage means 17. It can be set as the structure which makes one storing means suitable for a reduced scale.

  Next, the hierarchical map image display means 26 generates a three-dimensional map image of a predetermined range area including the position specified by the terminal device 3 from the three-dimensional data of one storage means selected in step S105, The three-dimensional map image is transmitted to the terminal device 3 so as to be displayed on the display unit 32 of the terminal device 3 (step S106) (hierarchical map image display step), and the display process is terminated.

  3-6 is a figure which shows the example of the three-dimensional map image displayed on the display part 32 of the terminal device 3 by the hierarchy map image display means 26. FIG. FIG. 3 shows an example of a three-dimensional map image based on the three-dimensional aviation data of the first storage means 11, and FIG. 4 shows an example of a three-dimensional map image based on the wide-area three-dimensional data of the second storage means 12. FIG. 5 shows an example of a three-dimensional map image based on the three-dimensional narrow ground data of the first narrow area data storage means 16 in the third storage means 13, and FIG. 6 shows the first narrow area data storage in the third storage means. The example of the three-dimensional map image by the narrow area | region ground three-dimensional data of the means 16 and the 2nd narrow area data storage means 17 is shown.

  In the range of scales that can be specified by the terminal device 3, when the specified scale is small (in the case of land and sea wide area specification) or when there is no scale specification from the terminal device 3, as shown in FIG. A three-dimensional map image that allows the plant 50 to be viewed over a wide area is displayed. In the range of scales that can be designated, when the designated scale is medium (in the case of land and sea narrow area designation), as shown in FIG. 4, the appearance of some equipment (structure 51) of the steel manufacturing plant 50 And a three-dimensional map image of a narrower area than that of FIG. 3, including the scenery around the equipment including the road 52 in the site of the steel plant 50. When the designated scale is large in the range of scales that can be designated (in the case of designating a wide area of the structure), as shown in FIG. 5, the external structure of the facility of the steel plant 50 is more detailed as a three-dimensional map image. Can be displayed. When the designated scale is very large in the range of the scale that can be designated (in the case of designating a narrow structure), not only the appearance of the equipment of the steel plant 50 but also the steel plant 50 as shown in FIG. The internal structure (the internal pipe 54, the internal passage 55, etc.) of the structure 51 that constitutes can be displayed as a three-dimensional map image. Furthermore, in the three-dimensional map image based on the three-dimensional water area data in the fourth storage means 14, it is possible to display a three-dimensional image of the underwater terrain or an underwater structure.

  As described above, the three-dimensional image display system 1 according to the present embodiment includes a wide area map of the terrain, a narrow area map of the terrain, a wide area map of the structure 51, and a narrow area map of the structure 51 (internal structure map of the structure 51). And underwater maps can be integrated and managed. Therefore, it has a vast site area, is installed near the coast, and is suitable for management of plant facilities that require detailed design drawings of the structure 51. In particular, by providing a water area map, it can be used for revetment work and is suitable for the management of plant facilities installed near the coast. Moreover, since a highly accurate three-dimensional map image of point cloud data can be used only in a necessary region, integrated management of plant facilities can be performed while suppressing the amount of data.

  Next, the update process of the three-dimensional data in the three-dimensional image display system 1 of the steel manufacturing plant 50 described above will be described.

  The three-dimensional data (three-dimensional data of the terrain and three-dimensional data of the structure) to be updated is transmitted from the terminal device 3 to the server 2 via the network 4. When the server 2 receives the three-dimensional data of the three-dimensional object, the data update unit 22 selects one storage unit from the first to fourth storage units 11, 12, 13, and 14 according to the three-dimensional data acquisition method.

  For example, when the user of the terminal device 3 transmits the three-dimensional data to the server 2, the storage unit is selected based on the specification of the acquisition method. The data updating unit 22 can select a storage unit. Further, the storage means is selected by designating the acquisition method of the three-dimensional data from the terminal device 3, and the data update means 22 is transmitted from the terminal device 3 with the accuracy of the point cloud data of the selected storage means. When the accuracy of the point cloud data is compared, and the accuracy is comparable, the data is stored in the selected storage means and the three-dimensional data is updated. 32 can be displayed. Further, the data updating unit 22 may select a storage unit having the same degree of accuracy of the point cloud data depending on the difference in accuracy of the three-dimensional data transmitted from the terminal device 3 (accuracy of the point cloud data). .

  When the storage unit is selected, the data update unit 22 updates a part or all of the three-dimensional data in the selected storage unit with the three-dimensional data received from the terminal device 3. Thereafter, the updated three-dimensional data is associated with the three-dimensional data of other storage means and stored in the storage unit 10.

  Since the data update means 22 can update the data for each of the storage means 11, 12, 13, and 14, it is possible to easily update the three-dimensional data with different acquisition methods. Therefore, when three-dimensional data regarding the steel plant 50 is changed due to renovation work, etc., it can be reflected in the three-dimensional data of other storage means by updating the three-dimensional data of one storage means. Further, it is possible to save the trouble of individually updating the terrain wide area map, the terrain narrow area map, the structure 51 wide area map, the structure 51 narrow area map, and the underwater map. As a result, the management cost of the steel manufacturing plant 50 can be reduced and the efficiency of management work can be improved. Further, when the data updating means 22 automatically selects the storage means, the user operation of the terminal device 3 becomes easier. Further, when a plurality of users use the 3D image display system 1, for example, when a plurality of terminal devices 3 are connected to the server 2, the users of the terminal devices 3 can perform tertiary using the latest 3D data. The original map image can be used.
