[0003] [Patent Document 1] JP 2017-040547 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, the above-mentioned conventional buried object detection device has the following problems. In other words, when exploring buried objects with the buried object exploration device disclosed in the above publication, a marking task is required to affix tape corresponding to the first scanning range, the second scanning range, and the side line to the concrete surface, which places a burden on the worker.

[0005] The object of the present invention is to provide a dimensional information management device that can effectively utilize exploration information of buried objects within a target object and reduce the burden on workers, as well as a dimensional information management system, a dimensional information management method, and a dimensional information management program that are equipped with the same. [Means for solving the problem]

[0006] A dimension information management device according to a first aspect of the present invention is a dimension information management device that manages dimensional information of buried objects contained in an exploration image that indicates the presence or absence of buried objects in an object and is generated by a buried object exploration device that scans along the object, and includes an acquisition unit and an exploration information storage unit. The acquisition unit acquires exploration information including the exploration image from the buried object exploration device. The exploration information storage unit stores the exploration information acquired by the acquisition unit.

[0007] Here, a buried object detection device scans the surface of an object such as a wall or concrete to detect buried objects such as wood or metal contained within the object, and obtains detection images indicating the presence or absence of buried objects. In a dimensional information management device that manages dimensional information of the buried objects, information including the detection images obtained by the acquisition unit is stored as detection information of the buried objects. Here, the dimension information management device includes, for example, a personal computer (PC) for a manager who manages a construction site, a smartphone owned by a worker, a tablet terminal, and the like.

[0008] The exploration information obtained from the buried object exploration device includes, for example, in addition to the exploration image, information such as dimensional (width) information in the scanning direction of the buried object contained in the exploration image, the distance from the scanning start point (reference point) to the buried object, and the distance between buried objects. This makes it possible to utilize the exploration information stored in the exploration image memory unit, for example by displaying the exploration information on a display device, thereby making it possible to grasp the position, size, etc. of buried objects without the need to perform marking work during construction. In addition, based on the exploration information stored in the exploration image storage unit, it is also possible to create a construction drawing showing the positions of buried objects within the target object and the positions of construction work such as screw fastening. As a result, construction work can be carried out based on the position, size, etc. of buried objects contained within the target object, thereby reducing the burden on workers.

[0009] The dimension information management device according to the second invention is the dimension information management device according to the first invention, further comprising an exploration information calling unit and a first display control unit. The exploration information calling unit calls up any information from the exploration information stored in the exploration information storage unit. The first display control unit displays the exploration information called up by the exploration information calling unit on the first display unit. As a result, by displaying exploration information such as exploration images called up from the exploration information memory unit on the first display unit, workers performing construction and construction managers can easily check the position and size of buried objects contained in the actual target object while checking the exploration information.

[0010] A dimensional information management device according to a third invention is a dimensional information management device according to the second invention, wherein the first display control unit controls the first display unit to display, as exploration information, position information of buried objects starting from the starting point of scanning included in the exploration image. This allows the position and size of the buried object to be displayed on the first display unit starting from the reference point where scanning by the buried object detection device began, making it easy for workers and others to recognize where the buried object is located in relation to the actual target object.

[0011] A dimensional information management device according to a fourth invention is a dimensional information management device according to any one of the first to third inventions, further comprising an input section into which construction information including positional information of buried objects within the target object is input.

[0012] Here, the construction information input to the input unit includes, for example, dimensional information regarding the position and size of buried objects contained within the target object, screw fastening positions into the buried object to be constructed, and information such as the type, size, and number of screws. This allows the construction information input into the input unit to be compared with the exploration information stored in the exploration information memory unit to confirm whether the exploration information matches the construction information, and then construction can be carried out.

[0013] The dimensional information management device of the fifth invention is a dimensional information management device of the fourth invention, and further includes a comparison unit that compares the exploration information stored in the exploration information memory unit with the construction information input into the input unit and determines whether they match. As a result, if the exploration information stored in the exploration information memory unit matches the construction information input into the input unit, construction work can be carried out using the exploration information and construction information.

[0014] A dimensional information management device according to a sixth aspect of the present invention is a dimensional information management device according to the fifth aspect of the present invention, wherein the comparison unit compares the exploration information with the construction information using the starting point of scanning included in the exploration image as a reference point. This makes it possible to easily determine whether the exploration information and construction information match by comparing the exploration information with the scanning start point included in the exploration image and the reference point attached to the target object.

[0015] A dimensional information management device according to a seventh aspect of the present invention is the dimensional information management device according to the fifth or sixth aspect of the present invention, wherein the matching unit matches the exploration information with the construction information using dimensional information related to the buried object. This makes it possible to easily determine whether the positions and sizes of buried objects are consistent by comparing the dimensions (width) and size in the scanning direction of the buried objects contained in the exploration information with the dimensional information of the buried objects contained in the construction information.

[0016] A dimensional information management device according to an eighth aspect of the present invention is a dimensional information management device according to the fifth or sixth aspect of the present invention, wherein the comparison unit pattern matches an exploration image including a buried object with a drawing included in the construction information, and compares the exploration information with the construction information. This makes it possible to easily determine whether the two match by pattern matching the exploration image containing the buried object contained in the exploration information with the drawing contained in the construction information and comparing the position and size of the buried object.

[0017] The dimensional information management device of the 9th invention is a dimensional information management device of any one of the 5th to 8th inventions, and further includes a construction drawing creation unit that creates a construction drawing based on the exploration information and the corresponding construction information when the exploration information matches the construction information as a result of the comparison in the comparison unit. Here, the construction drawing created by the construction drawing creation unit reflects, for example, the locations of buried objects within the target object that have been determined to be approximately consistent with the exploration information, and the locations at which construction objects such as screws are to be installed in the buried object that is the target of construction. This allows construction work to be carried out on actual objects and buried objects using construction drawings that are created based on a match between the exploration information and the construction information.

[0018] A dimensional information management device according to a tenth aspect of the present invention is a dimensional information management device according to the ninth aspect of the present invention, wherein the first display control unit controls the first display unit to display a construction drawing that reflects construction information in the exploration information. As a result, by looking at the display screen of the first display unit, which shows a construction drawing in which construction information is reflected in the exploration image, the worker can carry out construction work without having to mark objects such as walls.

[0019] The dimensional information management device of the 11th invention is a dimensional information management device of any one of the 4th to 10th inventions, wherein the construction information includes at least one of information regarding the name and dimensions of the buried object to be constructed, and the position, type, pitch, and number of screws to be constructed. This makes it possible to use construction information, including the name and dimensions of the buried object to be constructed, and the position, type, pitch, and number of screws to be constructed, to compare with the exploration image and reflect it in the exploration image.

[0020] The dimensional information management system of the 12th invention comprises a dimensional information management device of any one of the first to 11th inventions, and a buried object detection device including a data transfer unit that transfers a detection image to an acquisition unit of the dimensional information management device. This allows the dimension information management device, which receives the exploration image from the data transfer section of the buried object exploration device, to store the exploration image as exploration information.

[0021] The dimensional information management system of the 13th invention is a dimensional information management system of the 12th invention, wherein the buried object exploration device has a detection unit that detects the presence or absence of a buried object, a exploration image conversion processing unit that converts the detection result in the detection unit into a exploration image, a memory unit that stores the exploration image and a grid layer including grid lines corresponding to a predetermined scale, and a second display unit that displays the exploration image and the grid layer. As a result, for example, in a buried object detection device that detects buried objects such as wood or rebar contained within objects such as walls or concrete, the detection image converted from the detection results in the detection unit can be displayed on the second display unit in a superimposed state on a grid layer containing grid lines.

[0022] The dimensional information management system of the 14th invention is the dimensional information management system of the 13th invention, wherein the buried object exploration device further has an operation input unit to which various operations are input, and a second display control unit that controls the second display unit to display the exploration image and the grid layer in a superimposed manner and to display the exploration image in a state in which it can be moved relatively to the grid layer in response to input to the operation input unit.

[0023] This makes it possible for the buried object exploration device to display the exploration image in a state in which it can be moved relatively to the grid layer in response to input to the operation input unit. Therefore, for example, by moving the exploration image and the grid layer relatively so as to align the reference point with the grid lines, the spacing between the grid lines can be checked, and the distance from the reference point to the location of the buried object can be easily checked on the display screen of the second display unit without having to perform marking work on the wall surface. As a result, marking work during buried object exploration is no longer necessary, and the burden on workers can be reduced.

[0024] A dimensional information management method according to a fifteenth aspect of the present invention is a dimensional information management method for managing dimensional information of buried objects contained in an exploration image showing the presence or absence of buried objects in an object generated by a buried object exploration device scanning along the object, and includes an acquisition step and an exploration information storage step. In the acquisition step, exploration information including the exploration image is acquired from the buried object exploration device. In the exploration information storage step, the exploration information acquired in the acquisition step is stored.

[0025] Here, in a dimensional information management method in which an exploration image indicating the presence or absence of buried objects is obtained from a buried object exploration device that scans the surface of an object such as a wall or concrete to detect buried objects such as wood or metal contained within the object, and dimensional information of the buried objects is managed, information including the exploration image obtained in the acquisition step is saved as exploration information of the buried objects. Here, in the dimensional information management method, for example, a PC (Personal Computer) for a manager who manages a construction site, or a smartphone or tablet terminal owned by a worker, is used as a dimensional information management device.

[0026] The exploration information obtained from the buried object exploration device includes, for example, in addition to the exploration image, information such as dimensional (width) information in the scanning direction of the buried object contained in the exploration image, the distance from the scanning start point (reference point) to the buried object, and the distance between buried objects. This makes it possible to utilize the exploration information stored in the exploration image storage step, for example by displaying the exploration information on a display device, thereby making it possible to grasp the position, size, etc. of buried objects without the need to perform marking work during construction. In addition, based on the exploration information stored in the exploration image storage step, a construction drawing showing the positions of buried objects within the target object and the construction positions for screw fastening, etc. can also be created. As a result, construction work can be carried out based on the position, size, etc. of buried objects contained within the target object, thereby reducing the burden on workers.

[0027] A dimensional information management program according to a sixteenth aspect of the present invention is a dimensional information management method for managing dimensional information of buried objects contained in an exploration image showing the presence or absence of buried objects in an object generated by a buried object exploration device scanning along the object, the dimensional information management method including an acquisition step and an exploration information storage step, which causes a computer to execute the dimensional information management method. In the acquisition step, exploration information including the exploration image is acquired from the buried object exploration device. In the exploration information storage step, the exploration information acquired in the acquisition step is stored.

[0028] Here, an exploration image indicating the presence or absence of buried objects is obtained from a buried object exploration device that scans the surface of an object such as a wall or concrete to detect buried objects such as wood or metal contained within the object, and in a dimensional information management program that manages the dimensional information of the buried objects, information including the exploration image obtained in the acquisition step is saved as exploration information of the buried objects. Here, in the dimensional information management method, for example, a PC (Personal Computer) for a manager who manages a construction site, or a smartphone or tablet terminal owned by a worker, is used as a dimensional information management device.

[0029] The exploration information obtained from the buried object exploration device includes, for example, in addition to the exploration image, information such as dimensional (width) information in the scanning direction of the buried object contained in the exploration image, the distance from the scanning start point (reference point) to the buried object, and the distance between buried objects. This makes it possible to utilize the exploration information stored in the exploration image storage step, for example by displaying the exploration information on a display device, thereby making it possible to grasp the position, size, etc. of buried objects without the need to perform marking work during construction.

[0030] In addition, based on the exploration information stored in the exploration image storage step, a construction drawing showing the positions of buried objects within the target object and the construction positions for screw fastening, etc. can also be created. As a result, construction work can be carried out based on the position, size, etc. of buried objects contained within the target object, thereby reducing the burden on workers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0033] A dimensional information management system 1 including a dimensional information management device 40 according to one embodiment of the present invention will be described below with reference to Figs. 1 to 33. (1) Configuration of Dimensional Information Management System 1 As shown in FIG. 1, the dimensional information management system 1 according to this embodiment includes a buried object exploration device 10 and a dimensional information management device 40 (see FIGS. 3 and 25, etc.).

[0034] The buried object detection device 10 is moved along the surface of a wall (target object) 50 and detects changes in capacitance using a capacitance sensor 13 (see Figure 3) described later, thereby detecting buried objects 51 such as wood (pipe posts 51a, partition walls 51b) and metals contained within the wall 50. As shown in Figure 3, the dimensional information management device 40 is capable of communicating with the buried object detection device 10, receives detection information regarding buried objects 51 within a wall surface 50 from the buried object detection device 10, and manages dimensional information such as the position and size of the buried object 51.

[0035] (2) Configuration of buried object exploration device 10 As shown in FIG. 2, the buried object exploration device 10 includes a main body 11, a display unit (second display unit) 12, a capacitance sensor 13 (see FIG. 3), an optical sensor 14 (see FIG. 3), and an operation input unit 15. The wall surface 50 includes, for example, a plaster board or a wooden plywood with an interior material such as wallpaper attached to the surface. The embedded object 51 includes, for example, a wooden or metal frame such as a pillar, a beam, or a brace.

[0036] As shown in FIG. 2, the main body 11 is a resin member having an approximately rectangular parallelepiped shape, with a display unit 12 and an operation input unit 15 provided on the surface (front side) facing the user when in use, and a capacitance sensor 13 and an optical sensor 14 provided on the surface (back side) facing the wall surface 50 opposite the user. A recess 11a is provided on each of the top end surface and the left and right side end surfaces of the main body 11. When scanning the buried object exploration device 10 along the wall surface 50, these recesses 11a are used to mark the scanning start point on the wall surface 50 with, for example, a pen or the like.

[0037] 2, the display unit 12 is, for example, a liquid crystal display device, and is disposed on the surface of the main body unit 11. The display unit 12 displays, for example, settings of the buried object exploration device 10, an exploration image showing the detection result of the buried object 51, and the like, and the display content is switched according to the operation content input to the operation input unit 15. The capacitance sensor 13 is located on the back side of the main body 11 and is a sensor that detects changes in capacitance when the buried object detection device 10 is moved along the wall surface 50, and is used to detect buried objects 51 present within the wall surface 50.

[0038] The optical sensor 14 is disposed on the rear side of the main body 11 and receives infrared light reflected from the wall surface 50, for example, to obtain position information of the buried object exploration device 10. 2, the operation input unit 15 is disposed on the surface of the main body 11. The operation input unit 15 includes a power button 15a, a grid display button 15b, a scale switching button 15c, a cross key 15d, and an enter button 15e.

[0039] The power button 15a is located on the upper right side of the operation input unit 15, and, for example, when pressed and held down, the power of the buried object exploration device 10 is turned on or off. The grid display button 15b is disposed on the upper left side of the operation input unit 15, and is pressed when a grid layer, in which a plurality of grid lines described later are arranged in a lattice pattern, is displayed superimposed on the exploration image on the display screen 12a of the display unit 12. When the grid display button 15b is pressed again in a state in which the grid layer is displayed on the display screen 12a superimposed on the exploration image, a measurement grid (grid lines) is displayed on the display screen 12a.

[0040] The scale switching button 15c is disposed in the center of the upper part of the operation input unit 15, and is pressed, for example, when enlarging and displaying the exploration image and the grid layer that are displayed in an overlapping manner. The cross key 15d is disposed at the bottom of the operation input unit 15, and inputs operations in four directions, up, down, left, and right. For example, when a grid layer including grid lines is displayed superimposed on the exploration image, the cross key 15d is operated up and down or left and right to move the exploration image relatively to the grid layer.

[0041] The decision button 15e is disposed at the center of the cross key 15d, and is pressed to execute a command or the like selected using the cross key 15d or the like. In addition, as shown in Figure 3, the buried object exploration device 10 includes, within the main body 11, a capacitance acquisition unit 20, a position information acquisition unit 21, a memory unit 22, a buried object presence / absence determination unit 23, a dimension calculation processing unit 24, an exploration image conversion processing unit 25, a buried object estimation unit 26, an input acceptance unit 27, an exploration image calling unit 28, a data transfer unit 29, and a display control unit 30.

[0042] The capacitance acquisition unit 20, position information acquisition unit 21, memory unit 22, buried object presence / absence determination unit 23, dimension calculation processing unit 24, exploration image conversion processing unit 25, buried object estimation unit 26, input acceptance unit 27, exploration image calling unit 28, data transfer unit 29 and display control unit 30 generated within the buried object exploration device 10 are generated by the CPU reading various control programs stored in the memory.

[0043] The capacitance acquisition unit 20 acquires an output from the capacitance sensor 13 arranged on the back side of the main body unit 11 and transmits it to the storage unit 22 . More specifically, the capacitance acquisition unit 20 detects a change in capacitance to determine the presence or absence of a buried object 51 in the movement range of the buried object exploration device 10 using the position information acquired by the position information acquisition unit 21, each time the buried object exploration device 10 reaches a predetermined movement amount along the wall surface 50. As a result, the exploration image conversion processing unit 25 described later can generate an exploration image of the movement area for each predetermined movement amount, using the output result from the capacitance sensor 13.

[0044] The position information acquisition unit 21 acquires the output from the optical sensor 14 arranged on the back side of the main body unit 11, and transmits it to the storage unit 22. This enables the buried object exploration device 10 to detect its position on the wall surface 50 and the amount of movement thereof, based on the position information acquired by the position information acquisition unit 21. The storage unit 22 stores the capacitance data received from the capacitance acquisition unit 20, the position information data received from the position information acquisition unit 21, a buried object table (see FIG. 11) including dimensional information of the buried object 51 in the scanning direction of the buried object exploration device 10, the exploration image converted from the capacitance data in the exploration image conversion processing unit 25, a grid layer displayed superimposed on the exploration image, a reference point display layer, etc. Then, the storage unit 22 transmits the exploration image, etc. called up by the exploration image calling unit 28 to the data transfer unit 29 and the display control unit 30.

[0045] The exploration images stored in the storage unit 22 are grouped in units of one scan and stored together with time information of scanning the wall surface 50. In this embodiment, exploration images corresponding to multiple scans are stored in the storage unit 22. In addition, the exploration images converted for each specified amount of movement are accumulated and stored, for example, after the buried object exploration device 10 is turned on, and multiple exploration images are saved in a grouped state for each scan.

[0046] The buried object presence / absence determining unit 23 determines the presence / absence of a buried object 51 in the wall surface 50 depending on whether the output signal (capacitance data) of the capacitance sensor 13 exceeds a predetermined threshold value (edge ​​determination process). This makes it possible to determine the presence / absence of a buried object 51 based on the output result of the capacitance sensor 13. The dimension calculation processing unit 24 calculates an estimated value of the dimension (width, etc.) of the buried object 51 in the wall surface 50 based on the output signal (capacitance data) of the capacitance sensor 13. Specifically, the dimension calculation processing unit 24 detects the edge portions at both ends where the output signal of the capacitance sensor 13 changes, and calculates an estimated value of the dimension of the buried object 51 between them.

[0047] The exploration image conversion processing unit 25 converts the output signal of the capacitance sensor 13 into an exploration image indicating the presence or absence of a buried object 51. More specifically, the exploration image conversion processing unit 25 generates an exploration image based on the position information of the buried object exploration device 10 detected by the above-mentioned position information acquisition unit 21, using capacitance data acquired each time the movement amount of the buried object exploration device 10 along the wall surface 50 reaches a predetermined distance.

[0048] The buried object estimation unit 26 compares the estimated value of the dimension (width) in the scanning direction of the buried object 51 calculated by the dimension calculation processing unit 24 with the width dimensions for each type of buried object 51 contained in the buried object table (see Figure 11) stored in the memory unit 22, and estimates the type of the corresponding buried object 51. The input receiving unit 27 receives operation contents inputted from the user to the operation input unit 15 including the above-mentioned power button 15a, grid display button 15b, scale switching button 15c, cross key 15d, and the like.

[0049] The exploration image recall unit 28 recalls the exploration image stored in the memory unit 22 based on, for example, the operation content input by the user to the operation input unit 15, and transmits it to the data transfer unit 29 and the display control unit 30. In addition, after the exploration image is stored in the memory unit 22, the display control unit 30 may control the display unit 12 so that it is displayed in real time during scanning, regardless of the operation content input by the user to the operation input unit 15.

[0050] As shown in FIG. 3, the data transfer unit 29 transmits exploration information including the exploration image and the detection results of the buried object 51 to a dimensional information management device 40 such as a smartphone carried by a worker or the like. In addition, while Figure 3 shows that exploration information is transmitted from the data transfer unit 29 of the buried object exploration device 10 to one dimensional information management device 40, there may be multiple dimensional information management devices 40 to which exploration information is transmitted from the data transfer unit 29 of the buried object exploration device 10.

[0051] The display control unit 30 causes the display screen 12a of the display unit 12 to display an exploration image (see FIG. 4, etc.) indicating the presence or absence of a buried object 51, generated by the exploration image conversion processing unit 25 described above. Furthermore, the display control unit 30 causes the exploration image and the grid layer and reference point display layer stored in the storage unit 22 to be superimposed and displayed on the display screen 12a of the display unit 12. In the exploration image, as shown in FIG. 4, the presence or absence of a buried object 51 is displayed by combining multiple exploration images generated from capacitance data acquired along the trajectory of the buried object exploration device 10 scanning along the wall surface 50.

[0052] As shown in FIG. 3, the display control unit 30 includes a grid display processing unit 31, an exploration image display processing unit 32, and an origin display processing unit 33. The grid display processing unit 31 performs display processing to superimpose a grid layer including a plurality of grid lines, or a grid layer including a measurement grid (grid lines) prepared to clearly display the dimensions of the buried object 51, the distance to the buried object 51, etc., on the exploration image.

[0053] The exploration image display processing unit 32 performs a scroll process for moving the exploration image relative to the fixedly displayed grid layer on the display screen 12a of the display unit 12, and displays the dimensions of the buried object 51 included in the exploration image on the display screen 12a. Furthermore, the exploration image display processing unit 32 performs a process for switching the display scale of the exploration image displayed on the display screen 12a. The origin display processing unit 33 performs processing for displaying the reference point P1 on a grid layer displayed on the display screen 12a so as to be superimposed on the exploration image.

[0054] The grid layer is a display layer (see FIG. 20(a) and the like) including a plurality of grid lines arranged in a grid pattern, and is displayed superimposed on the exploration image indicating the presence or absence of the buried object 51. The display control unit 30 causes the display unit 12 to display the exploration image in a movable state relative to the grid layer. The reference point display layer, for example, displays a reference point P1 (see FIG. 18, etc.) indicating the scanning start point, superimposed on the search image and the grid layer on the display screen 12a of the display unit 12. Then, like the search image, the reference point display layer is displayed superimposed on the search image and the grid layer in a state in which it is movable relative to the fixedly displayed grid layer (see FIG. 20(b)). The display control of the display unit 12 by the display control unit 30 will be described in detail later.

[0055] <Generating and saving exploration images> In the buried object detection device 10 of this embodiment, with the configuration as described above, a detection image indicating the presence or absence of a buried object 51 within the wall surface 50 is generated based on the change in capacitance obtained as a result of scanning along the wall surface 50.

[0056] The process of generating the exploration image will now be described with reference to the flowchart of FIG. That is, in step S11, the capacitance acquisition unit 20 acquires the capacitance detected by the capacitance sensor 13. Next, in step S12, the position information acquisition unit 21 acquires the position information of the buried object exploration device 10 detected by the optical sensor . Next, in step S13, it is determined whether or not the buried object exploration device 10 has moved along the wall surface 50, based on the position information of the buried object exploration device 10 acquired by the position information acquisition unit 21. If it is determined that the buried object exploration device 10 has moved, the process proceeds to step S14, and if it is determined that the buried object exploration device 10 has not moved, step S13 is repeated until it is determined that the buried object exploration device 10 has moved.

[0057] Next, in step S14, since it has been determined in step S13 that the buried object exploration device 10 has moved, the coordinates (relative coordinates) indicating the current position of the buried object exploration device 10 are calculated and acquired. Next, in step S15, the coordinates of the current position of the buried object exploration device 10 calculated and acquired in step S14 are calculated and acquired as relative coordinates, and the process proceeds to step S16.

[0058] This allows the capacitance data acquired by the capacitance acquisition unit 20 to be stored, for example, each time the position information acquisition unit 21 detects that the position of the buried object detection device 10 detected by the optical sensor 14 has reached a predetermined amount of movement. Next, in step S16, the buried object presence / absence determining unit 23 performs a process of determining the presence or absence of the buried object 51 in the scanning range based on the acquired capacitance data.

[0059] Next, in step S17, buried object presence / absence determining section 23 determines whether or not a buried object 51 is present. If present, the process proceeds to step S18, and if not, the process proceeds to step S19. Next, in step S18, since it was determined in step S17 that a buried object 51 is present, the dimension calculation processing unit 24 calculates an estimated value of the dimension (width) of the buried object 51 in the scanning direction of the buried object exploration device 10.

[0060] Next, in step S19, regardless of the presence or absence of the buried object 51, the exploration image conversion processing unit 25 performs a process of converting the capacitance data acquired by the capacitance acquisition unit 20 into an exploration image. Next, in step S20, the exploration image generated in step S19 is stored in the storage unit 22. In this embodiment, by the above-described process, a probe image is generated using the capacitance data detected by the capacitance sensor 13 and is stored in the storage unit 22.

[0061] <Start of scanning ~ Image storage> Next, the steps from the start of scanning along the wall surface 50 to the storage process of the exploration image in the buried object exploration device 10 of this embodiment will be described below with reference to the flowcharts of FIGS.

[0062] (a) Coordinate acquisition process The coordinate acquisition process in S14 of FIG. 5, which is performed in the buried object exploration device 10 of this embodiment, will be described in detail below with reference to the flowchart of FIG. In this embodiment, when scanning along the wall surface 50 is started using the buried object exploration device 10, as shown in FIG. 6, in step S21, position information detected by the optical sensor 14 is obtained as coordinate change amount (X, Y). Next, in step S22, the coordinate change amount acquired in step S21 is added to the accumulated coordinate. Next, in step S23, the accumulated coordinates obtained in step S22 are set as the current position of the buried object exploration device 10.

[0063] (b) Buried object presence / absence determination process The process of determining the presence or absence of a buried object 51 in S17 of FIG. 5, which is carried out by the buried object exploration device 10 of this embodiment, will be described in detail below with reference to the flowchart of FIG.

[0064] First, in step S31, the amount of change in the detection result of the capacitance detected by the capacitance sensor 13 is calculated as a determination value. Next, in step S32, it is determined whether the judgment value is equal to or greater than a predetermined threshold value. If the judgment value is equal to or greater than the predetermined threshold value, the process proceeds to step S33, and if the judgment value is less than the predetermined threshold value, the process proceeds to step S34. Next, in step S33, since it is determined in step S32 that the determination value is equal to or greater than the predetermined threshold value, it is determined that the buried object 51 is present in that scanning area, and the process ends. On the other hand, in step S34, since it is determined in step S32 that the determination value is less than the predetermined threshold value, it is determined that there is no buried object 51 in that scanning area, and the process ends.

[0065] (c) Buried object estimation processing The process of estimating the buried object 51 in S18 of FIG. 5, which is carried out by the buried object exploration device 10 of this embodiment, will be described in detail below with reference to the flowchart of FIG.

[0066] First, in step S41, the continuous width (length) in the scanning direction of buried object 51 before and after the current position of buried object exploration device 10 is acquired from the acquired data storage table shown in FIG. Here, the acquired data storage table includes information on acquisition time, coordinates (X, Y), detection results of the capacitance sensor, buried object determination results, buried object type, and dimensions, as shown in FIG.

[0067] The type of buried object included in the acquired data storage table shown in FIG. 12 is acquired as a result of estimating the type of buried object 51 by referring to the width dimension among the information on the name, width, and thickness for each type of buried object 51 shown in FIG. 11 and comparing it with the estimated value of the dimension of the detected buried object. Next, in the processing of steps S42 to S46, the buried object table shown in FIG. 11 is referenced (S43), and the number of materials (foundations, through columns, pipe columns, partition walls, beams, diagonal braces, rafters, furring strips, etc.) that match the continuous width (length) in the scanning direction of the buried object 51 acquired in step S41 are repeatedly checked (S44).

[0068] Then, in step S44, if the width dimension substantially matches any of the buried objects 51 included in the buried object table, the process proceeds to step S46 to estimate the type of the buried object 51. Then, the buried object table is returned so as to reflect the estimation result, and the process ends. On the other hand, in step S44, if the width dimension does not match any of the buried objects 51 included in the buried object table, the processes of steps S42 to S46 are repeated until all types in the buried object table have been checked, and then the process ends.

[0069] (d) Exploration image conversion processing The exploration image conversion process in S19 of FIG. 5, which is performed in the buried object exploration device 10 of this embodiment, will be described in detail below with reference to the flowchart of FIG. First, in step S51, the amount of change (determination value) in the detection result of the capacitance sensor calculated in S31 of the buried object presence / absence determination process shown in FIG. 7 is converted into 255 gradations of brightness.

[0070] Next, in step S52, the position coordinates included in the acquired data storage table shown in FIG. 12 are drawn in the display buffer area with the converted brightness to generate a search image. In addition, as shown in FIG. 13, the coordinates (X, Y) and the corresponding R·G·B values ​​are stored in the display buffer area. Next, in step S53, it is determined whether or not it has been possible to determine the dimensions of the buried object 51. If it has been possible to determine the dimensions, the process proceeds to step S54, and if it has not been possible to determine the dimensions, the process ends. Next, in step S54, the buried object 51 whose dimensions have been determined and its dimensions (scanning direction) are stored in the acquired data storage table shown in FIG. 12, and the process ends.

[0071] (e) Exploration image storage processing The storage process of the exploration image in S20 of FIG. 5, which is carried out in the buried object exploration device 10 of this embodiment, will be described in detail below with reference to the flowchart of FIG.

[0072] First, in step S61, it is determined whether or not an image clear operation such as pressing an exploration start button by the user has been accepted. If an image clear operation has been received, the process proceeds to step S62, and if not, the process ends. Next, in step S62, the search image in the display buffer area shown in FIG. 13 is registered in a search image storage table shown in FIG. 14 before the screen is cleared.

[0073] Here, the search image storage table stores the date and time when the search image was generated in association with the image data ID assigned to each search image, as shown in Fig. 14. Note that the search image stored in the search image storage table is stored as image data corresponding to one operation. Next, in step S63, the display buffer area is cleared, and the process ends.

[0074] <Display control method for buried object exploration device 10> The display control method of the buried object exploration device 10 of this embodiment will be described below with reference to Figs. (a) Startup and preparation First, as shown in FIG. 15, when the user operates (long presses) the power button 15a in step S71, the display control unit 30 causes the display screen 12a of the buried object exploration device 10 to display a start-up screen in step S72.

[0075] Next, in step S73, the display control unit 30 causes the display screen 12a of the buried object exploration device 10 to display the start-up screen, followed by an exploration initial screen. The initial search screen is, for example, as shown in FIG. 16, a screen in which a square is displayed in the center of the display screen 12a. Next, in step S74, the user presses the back side of the main body 11 of the activated buried object detection device 10 against the construction surface (wall surface 50) to be detected, and engages a pen or the like with the recess 11a to mark a reference point P1, which will be the starting point for scanning, on the wall surface 50, thereby setting the initial position for the start of scanning.

[0076] (b) Exploration scan Next, as shown in FIG. 17, in step S75, the user moves the buried object exploration device 10 along the wall surface 50 to scan along the construction surface. Next, in step S76, the display control unit 30 (exploration image display processing unit 32, origin display processing unit 33) displays an exploration image showing the exploration results of the scanned range and a reference point display layer including reference point P1 on the display screen 12a of the buried object exploration device 10.

[0077] As shown in FIG. 18(a), this inspection screen displays a scanning area A1 scanned by the buried object inspection device 10, detection areas S1 and S2 indicating a buried object 51 in the scanning area A1, and a reference point P1 where scanning began. Next, in step S77, the user causes the buried object exploration device 10 to further scan along the wall surface 50. Next, in step S78, when exploration data is accumulated by further scanning in step S77, the display control unit 30 (exploration image display processing unit 32) displays the calculation results (6 cm, 3 cm) of the dimensions (width) in the scanning direction of the detected buried object 51 on the exploration image, as shown in Figure 18 (b).

[0078] (c) Grid display and alignment operations 19, in step S79, after completing one scan, the user moves the buried object exploration device 10 away from the wall surface 50 and presses the grid display button 15b. Note that if the grid display button 15b is pressed first, scanning may be performed with the grid layer displayed.

[0079] Next, in step S80, the display control unit 30 (grid display processing unit 31) displays a grid layer including a plurality of grid lines G1 arranged in a grid pattern on the display screen 12a of the display unit 12, superimposed on the exploration image, as shown in FIG. 20(a). Next, in step S81, when the user operates the cross key 15d in the up, down, left or right direction on the display screen 12a shown in Figure 20(a), the exploration image and the reference point display layer including the reference point P1 move relative to the grid layer including the fixedly displayed grid line G1.

[0080] Next, in step S82, when the user operates the cross key so that the position of the reference point P1 coincides with a predetermined position of the guide line, the position of the reference point P1 can be aligned with a predetermined position of the grid line included in the grid layer, as shown in FIG. 20(b). This makes it possible to recognize the position (distance) of buried object 51 from reference point P1, the shape of buried object 51, and the like on display screen 12a.

[0081] (d) Distance and size of buried objects measured by measurement grid Next, as shown in FIG. 21, in step S83, when the user presses the grid display button 15b again, the display control unit 30 (grid display processing unit 31) displays the measurement grid (grid lines) G2 shown in FIG. 22(a) on the display screen 12a. As shown in FIG. 22(a), the displayed measurement grid G2 has narrower spacing than the grid lines shown in FIG. 20(a) etc., so the user can visually measure the distance and dimensions of the buried object 51 from the reference point P1 while looking at the display screen 12a.

[0082] Next, in step S84, the user operates the cross key 15d, and the display control unit 30 (exploration image display processing unit 32) moves the exploration image and the reference point display layer relative to the measurement grid G2 in order to accurately measure the distance between the reference point P1 and the buried object 51, with a grid layer including the measurement grid G2 superimposed on the exploration image. As a result, for example, if the interval of the measurement grid G2 shown in FIG. 22(a) is 5 cm, the user can recognize that the distance from the reference point P1 to the detection area S1 is approximately 15 cm while looking at the display screen 12a.

[0083] Next, in step S85, when the user presses the scale switching button 15c, in step S86, the display control unit 30 (exploration image display processing unit 32) enlarges and displays the area indicated by the dotted line in FIG. 22(a) as shown in FIG. 22(b). For example, if the spacing of the measurement grid (grid lines) G3 shown in FIG. 22(b) is 1 cm, the user can measure the dimensions in more detail while looking at the display screen 12a, such as that the width of the buried object 51 in the detection area S1 is approximately 6 cm, the width of the buried object 51 in the detection area S2 is approximately 3 cm, and the spacing between the buried objects 51 in the detection areas S1 and S2 is approximately 12 cm.

[0084] (e) Turn off the power during construction work Next, as shown in FIG. 23, based on the distance from reference point P1 to buried object 51 measured on display screen 12a by the processing up to step S86, first, in step S87, the user marks a position 15 cm horizontally from the position on wall surface 50 marked as reference point P1 as the position of the end of buried object 51 in order to grasp the actual position of buried object 51.

[0085] At this time, marking can be performed only at the construction position and at the position where buried objects are present. Next, in step S88, the user performs various construction works while recognizing the position of the buried object 51 marked on the wall surface 50. That is, while checking the positions of the reference point P1 and the detection areas S1, S2 of the buried object 51 displayed on the display screen 12a of the buried object detection device 10, the user performs processing on the wall surface 50 (marking if necessary) using the distance between the reference point P1 and the buried object 51 displayed on the display screen 12a, the dimensions of the buried object 51, etc., as shown in Figure 24. Thereafter, the user presses the power button 15a to turn off the power, and the operation is completed.

[0086] (3) Configuration of the dimensional information management device 40 The dimensional information management device 40 is, for example, a smartphone or tablet terminal owned by a worker, or a PC (Personal Computer) for an administrator, and as shown in Figure 25, is equipped with a data receiving unit (acquisition unit) 41, an exploration information registration unit 42, a memory unit (exploration information memory unit) 43, an input unit 44, a construction information registration unit 45, an exploration information call-up unit 46, a comparison unit 47, a construction drawing creation unit 48, a display control unit (first display control unit) 49 and a display unit (first display unit) 49a.

[0087] As shown in Figure 26, the dimensional information management device 40 displays, on the display screen of the display unit 49a of a smartphone or the like, an image display area A2 that displays an exploration image selected from the exploration information obtained from the buried object exploration device 10, and a data selection area A3 that shows a list of exploration information registered in the memory unit 43. The data receiving section (acquiring section) 41 communicates with the data transferring section 29 (see FIG. 3) of the buried object exploration device 10, and acquires exploration information including the exploration image generated by the buried object exploration device 10.

[0088] The exploration information registration unit 42 causes the exploration information received by the data receiving unit 41 from the buried object exploration device 10 to be registered (saved) in an exploration information registration DB in the storage unit 43. As shown in Figure 25, the memory unit (exploration information memory unit) 43 has an exploration information registration DB in which exploration information obtained from the buried object exploration device 10 is registered, and a construction information registration DB in which construction information input by workers, etc. is registered.

[0089] The input unit 44 is, for example, a touch panel of a dimension information management device 40 such as a smartphone shown in FIG. 26, and construction information is input by a worker or the like. The construction information registration unit 45 registers (stores) the construction information input to the input unit 44 in the construction information registration DB of the storage unit 43. Here, the construction information input from the input unit 44 includes, as shown in FIG. 27(a), the name of the buried object (pillar A) and its width, and information on the strength (large, medium, small) of the construction such as screws to be installed into the buried object (pillar A), the number (1, 1, 2), pitch (-, -, 15), size (M10, M8, M4), and screw fastening position.

[0090] The buried object (pillar A) to be constructed, which has been input to the input unit 44, is displayed with a drawing ID of 1, as shown in FIG. 27(b). The construction information registered in the construction information registration DB of the storage unit 43 by the construction information registration unit 45 is stored in such a manner that the width, strength of construction objects such as screws, number, pitch, size, etc. are organized for each buried object (pillars A, B, C, ...) to be constructed, as shown in Fig. 27(c). This allows a worker or the like to check a list of registered construction information while looking at the display screen displayed on the display unit 49a of the dimension information management device 40, for example.

[0091] Then, in the construction information registration DB, as shown in Figure 28, the construction information is stored as a drawing showing the position of each buried object (pillars A, B, C, D) based on the construction information registered in the list of Figure 27(c), with the reference point P1 where the scanning of the buried object detection device 10 started and the screw fastening position P2 added. The reference point P1 is used as a reference point when comparing with the exploration image included in the exploration information acquired from the buried object exploration device 10.

[0092] 28 shows a drawing created for screwing work from a wall surface 50 to the positions of buried objects 51 (pillars A, B, C, and D) present in the wall surface 50. The exploration information calling unit 46 calls up the exploration information registered in the exploration information registration DB of the storage unit 43 and transmits it to the display control unit 49. The collation unit 47 collates the exploration information received from the exploration information registration DB in the storage unit 43 with the construction information received from the corresponding construction information registration DB. Then, the collation unit 47 compares the exploration information and the construction information at corresponding positions to determine whether they match, that is, whether the position of the buried object 51 in the exploration image detected by the buried object exploration device 10 matches the position of the buried object 51 on the drawing.

[0093] Specifically, as shown in Figure 29, the drawing showing the positions of buried objects (pillars A, B, C, and D) obtained from the construction information of drawing ID: 1 in the upper row is compared with the positions of each buried object in the exploration image obtained as exploration information in the lower row. Here, the drawing in the upper part and the exploration image in the lower part are matched with each other based on the above-mentioned reference point P1.

[0094] At this time, the comparison to determine whether the two match may be performed using dimensional information such as the distance from the reference point P1 to each buried object, the spacing between the buried objects 51, and the width of the buried objects, or may be performed by pattern matching between the drawing and the exploration image based on the reference point P1. If the comparison unit 47 determines that the two match, the construction drawing creation unit 48 creates a construction drawing that reflects construction information such as the screw fastening position P2 in the exploration image showing the position of the buried object 51.

[0095] In the collation shown in FIG. 29, as shown in FIG. 30, a plurality of parts corresponding to each of the exploration information 1, 2, and 3 may be synthesized to create one drawing of construction information, and then collation may be performed. Then, as shown in Figures 31(a) to 31(c), the construction drawing creation unit 48 creates a construction drawing in which the screw fastening position P2 included in the drawing of the construction information is reflected in the exploration images of the exploration information 1 to 3. A display control unit (first display control unit) 49 performs control so that exploration information, construction drawings, and the like are displayed on the display screen of a display unit 49a shown in FIG. The display unit (first display unit) 49a displays exploration information, construction drawings, and the like as a display device, and is also used as the touch panel type input unit 44 described above.

[0096] <Exploration information analysis processing> With the above-described configuration, the dimension information management device 40 of this embodiment performs an analysis process of the exploration information acquired from the buried object exploration device 10 in accordance with the flowchart shown in FIG.

[0097] That is, in step S101, the data receiving unit 41 of the dimension information management device 40 acquires the exploration information including the exploration data and the exploration image from the data transfer unit 29 of the buried object exploration device 10. Next, in step S102, the exploration information registration unit 42 registers (stores) the exploration information received by the data receiving unit 41 in step S101 in the exploration information registration DB of the storage unit 43.

[0098] Next, in step S103, the exploration information calling unit 46 calls the exploration information registered in the storage unit 43 from the exploration information registration DB. Next, in step S104, the construction information registration unit 45 registers (stores) the construction information input from the input unit 44 in the construction information registration DB of the storage unit 43. Next, in step S105, the comparison unit 47 compares the construction information (drawings, etc.) registered in the construction information registration DB of the memory unit 43 in step S104 with the exploration information (exploration images, etc.) registered in the exploration information storage DB.

[0099] Next, in step S106, if the result of the collation by the collation unit 47 indicates that the two are substantially identical, the process proceeds to step S107. On the other hand, if the result of the collation by the collation unit 47 indicates that the two are not identical, it is determined that, for example, the position of the buried object 51 obtained from the exploration information is deviated from the actual position, and the process ends. Here, the matching work by the matching unit 47 in step S106 is performed as described above by comparing dimensional information such as the position and spacing of the buried object 51 based on the reference point P1, or by comparing the drawing and the exploration image by pattern matching.

[0100] Next, in step S107, since the comparison in step S106 determines that the two are substantially identical, the construction drawing creation unit 48 creates a construction drawing that reflects the construction method (construction position, etc.) for the buried object 51 included in the construction information for the buried object 51 in the exploration information (exploration image). Here, the above-mentioned construction method includes information on the details of construction such as screw fastening to the buried object 51, the size of the screws to be used, and the like. Next, in step S108, the display control unit 49 controls the display unit 49a to display the construction drawings created by the construction drawing creation unit 48.

[0101] <Registration process of construction information> Next, the processing flow when construction information input by a worker or the like via the input unit 44 in the dimensional information management device 40 of this embodiment is registered in the construction information registration DB of the memory unit 43 will be explained using the flowchart shown in Figure 33.

[0102] That is, in step S111, the dimension information management device 40 acquires working drawing information via the input unit 44. Next, in step S112, construction information for buried objects such as pillars to be constructed is input via the input unit 44 based on the construction drawing information acquired in step S111.

[0103] Next, in step S113, the construction information registration unit 45 registers the construction information including the construction drawings in the construction information management DB of the storage unit 43. Next, in step S114, it is determined whether there are any other drawings to be imported, and if there are no other drawings to be imported, the process ends. On the other hand, if there are other drawings to be imported, the process of steps S111 to S114 is repeated until there are no more drawings to be imported.

[0104] [Other embodiments] Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment, and various modifications are possible without departing from the gist of the invention. (A) In the above embodiment, the present invention has been described as an example of the dimension information management device 40, the dimension information management system 1 including the same, and the dimension information management method. However, the present invention is not limited to this.

[0105] For example, the present invention may be realized as a dimension information management program that causes a computer to execute the dimension information management method of the dimension information management device 40 described above. This dimension information management program is stored in a memory (storage unit) mounted on the dimension information management device, and the CPU reads the dimension information management program stored in the memory and causes the hardware to execute each step. More specifically, the CPU reads the dimension information management program and executes an acquisition step of acquiring exploration information including an exploration image from the buried object exploration device, and an exploration information storage step of storing the exploration information acquired in the acquisition step, thereby achieving the same effects as those described above. Furthermore, the present invention may be realized as a recording medium storing a dimensional information management program for use by the dimensional information management device.

[0106] (B) In the above embodiment, an example has been described in which the dimensional information management device 40 of the present invention is provided as a device separate from the buried object exploration device 10, such as a smartphone, a tablet terminal, or an administrator's PC that can communicate with the buried object exploration device 10. However, the present invention is not limited to this. For example, the present invention may be realized as a buried object detection device having the function of a dimensional information management device. That is, the buried object exploration system of the present invention may be provided within a buried object exploration device.

[0107] (C) In the above embodiment, an example was described in which the present invention is applied to a capacitance-type buried object exploration device 10 that uses a capacitance sensor 13 as a detection unit. However, the present invention is not limited to this. For example, the present invention may be applied to an electromagnetic wave type buried object exploration device that detects the position of a buried object by receiving a reflected wave of an electromagnetic wave irradiated onto concrete or a wall material.

[0108] (D) In the above embodiment, an example was described in which the optical sensor 14 is used as the scanning section that detects the amount of movement on the wall surface of the buried object exploration device 10. However, the present invention is not limited to this. For example, a scanning unit that employs a method other than the optical method may be used to detect the amount of movement of the buried object exploration device on the wall surface.

[0109] (E) In the above embodiment, an example has been described in which a grid layer including grid lines is fixedly displayed and the exploration image is moved to display the exploration image in a state in which the exploration image can be moved relatively to the grid layer. However, the present invention is not limited to this. For example, the exploration image may be displayed in a fixed state, and the grid layer may be displayed in a movable state. Alternatively, both the probe image and the grid layer may be displayed in a movable manner as required.

[0110] (F) In the above embodiment, an example was described in which the buried object exploration device 10 was used to detect wooden materials (pillars, foundations, beams, braces, etc.) contained within a wall surface made of gypsum board, wooden plywood, etc. However, the present invention is not limited to this.

[0111] For example, buried objects detected by the buried object detection device may be made of other materials, such as metal materials, resin materials, etc., in addition to wooden materials. Similarly, the target object may be a wall surface such as plaster board or wooden plywood, or may be made of other materials such as concrete. That is, the buried object exploration device of the present invention may be used, for example, to detect other materials or foreign objects present underground.

[0112] (G) In the above embodiment, an example was described in which the cross key 15d was used to move the exploration image and the reference point display layer relative to the fixedly displayed grid layer on the display screen 12a of the display unit 12 of the buried object exploration device 10. However, the present invention is not limited to this.

[0113] For example, the buried object exploration device may be actually moved on the wall surface, and the exploration image may be moved based on information on the amount of movement detected using an encoder, a tracking sensor, or the like. Alternatively, the probe image may be moved by manipulating a cursor on the table, for example, 1 mm for one move, 2 mm for two moves, etc., in response to a time change at the button.

[0114] (H) In the above embodiment, an example was given in which three types of grid layers, namely, the standard grid line G1, the measurement grid G3, and the measurement grid G3 during enlarged display, were used. However, the present invention is not limited to this. For example, it is preferable to use a grid layer in which grid lines are arranged at appropriate intervals depending on the size (dimension in the scanning direction) of the buried object to be detected.

[0115] (I) In the above embodiment, an example has been described in which the dimension information management device 40 compares the exploration information including the exploration image acquired from the buried object exploration device 10 with the construction information to create a construction drawing. However, the present invention is not limited to this. For example, the main feature of the dimensional information management device may be to display exploration information on a display unit using exploration information including an exploration image acquired from a buried object exploration device. Alternatively, the dimensional information management device may generate construction information using exploration information including an exploration image acquired from a buried object exploration device.

[0116] (J) In the above embodiment, an example has been described in which the exploration image and the construction information are compared based on the reference point P1 indicating the scanning start point of the buried object exploration device 10. However, the present invention is not limited to this. For example, when scanning is started with the edge of a wall as a reference point, the position of buried objects, etc. may be collated with the edge of the wall as a reference point without setting a reference point.

[0117] (K) In the above embodiment, an example has been described in which a mobile terminal such as a smartphone owned by a worker is used as the dimension information management device, but the present invention is not limited to this.

[0118] For example, a PC (Personal Computer) for an administrator of a construction company that carries out construction work may be used as the dimension information management device. In this case, the manager can check information such as the location of buried objects while displaying the exploration information and construction information displayed on the PC on the monitor screen. Therefore, since there is no need to mark the wall surface to indicate the location of the detected buried object, the burden on the worker can be reduced.

[0119] (L) In the above embodiment, an example has been described in which the search information including the search image is displayed on the display screen of the display unit 49a of the dimension information management device 40. However, the present invention is not limited to this. For example, a grid layer including a plurality of grid lines displayed in a buried object exploration device may be displayed superimposed on an exploration image on the display screen of the dimensional information management device.

[0120] In this case, the position of the buried object from the reference point, the distance between buried objects, the width of the buried object (dimension in the scanning direction), etc. can be easily recognized on the display screen of the dimensional information management device by referring to the grid lines. [Industrial Applicability]

[0121] The dimensional information management device of the present invention can carry out construction work based on the position, size, etc. of buried objects contained within the target object, thereby having the effect of reducing the burden on workers, and therefore can be widely applied as various devices for managing exploration images detected using a buried object exploration device.
