[0008] However, the following problem arises with the conventional device for scanning embedded objects mentioned above.

[0009] In the device for scanning embedded objects disclosed in the above-mentioned publication, the worker must perform a marking when searching for an embedded object, whereby a band is attached to the concrete surface according to a first scanning area, a second scanning area and side lines, and this increases the amount of work to be performed by the worker.

[0010] The present invention is based on the objective of providing a device for scanning embedded objects, with which search information about an embedded object in a measurement object can be used effectively and the worker's workload can be reduced, as well as a system for managing dimensional information comprising this device, a method for managing dimensional information and a program for managing dimensional information.

[0011] The device for managing dimensional information according to a first embodiment manages dimensional information about an embedded object contained in a search image that shows the presence or absence of an embedded object in a measurement object and is generated by a device for scanning embedded objects that performs a scan along the measurement object. The device for managing dimensional information comprises a detection unit and a search information storage unit. The detection unit detects search information comprising the search image from the device for scanning embedded objects. The search information storage unit stores the search information detected by the detection unit.

[0012] In a device for managing dimensional information, which manages dimensional information about an embedded object by capturing a search image showing the presence or absence of an embedded object from a device for scanning embedded objects, which performs a scan on the surface of a measurement object, such as a wall surface or concrete, to detect the embedded objects, such as wood and metal, contained in the measurement object, the information comprising the search image captured by the scanning unit is stored as search information about the embedded object.

[0013] The device for managing dimensioning information includes, for example, a PC (personal computer) used by a manager who manages a construction site, or a smartphone, tablet device, or the like, owned by a worker.

[0014] In addition to the search image, the search information acquired by the device for scanning embedded objects includes, for example, dimensional (width) information in the scanning direction of the embedded object contained in the search image, the distance from the scanning start point (reference point) to the embedded object, the distance between embedded objects, and other such information.

[0015] Consequently, the position, size, and so on of an embedded object can be determined without the need for marking work during construction, for example by using the search information stored in the search image storage unit and displaying the search information on the display device.

[0016] Furthermore, based on the search information stored in the search image storage unit, a design drawing can be created that shows the position of the embedded object in the measured object, screw positions and other such design positions.

[0017] Consequently, the design work can be carried out based on the position, size, and so on of embedded objects contained in the object being measured, which reduces the workload on the workers.

[0018] The device for managing dimensional information according to a second embodiment is the device for managing dimensional information according to the first embodiment, further comprising a search information retrieval unit and a first display control unit. The search information retrieval unit can retrieve any of the information from the search information stored in the search information storage unit. The first display control unit causes a first display unit to display the search information retrieved by the search information retrieval unit.

[0019] Consequently, by causing the first display unit to show search information, such as a search image retrieved from the search information storage unit, a worker, supervisor, or the like performing the construction can easily verify the position and size of embedded objects containing an actual measurement object when checking the search information.

[0020] The device for managing dimensional information according to the third embodiment is the device for managing dimensional information according to the second embodiment, wherein the first display control unit controls the first display unit in such a way that it displays as the search information position information about the embedded object, the origin of which is the starting point of the scanning that is contained in the search image.

[0021] Consequently, a worker or the like can easily verify where an embedded object is located in relation to an actual measurement object by causing the first display unit to show the position and size of the embedded object using the reference point at which the scanning with the embedded object scanning device is started.

[0022] The device for managing dimensional information according to one of the first to third embodiments further comprises an input unit into which design information is entered, which includes position information about the embedded object in the object being measured.

[0023] The design information entered into the input unit includes, for example, dimensional information about the position and size of the embedded objects contained in the measurement object, the screw positions to be designed in the embedded object, the type and size of screws, and so on.

[0024] Consequently, the design information entered into the input unit can be compared with the search information stored in the search information storage unit to see if the search information matches the design information before the design is executed.

[0025] The device for managing dimensional information according to one of the first to third embodiments further comprises a matching unit that compares the search information stored in the search information storage unit with the design information entered into the input unit and determines whether there is a match or not.

[0026] If, as a result of the comparison between the search information stored in the search information storage unit and the design information entered into the input unit, a match is found, the design work can consequently be carried out using this search information and design information.

[0027] The device for managing dimensional information according to the fourth embodiment is the device for managing dimensional information according to one of the first to third embodiments, wherein the matching unit matches the search information with the design information by using the scanning start point contained in the search image as a reference point.

[0028] Consequently, the search information and the design information can be compared using the scanning start point contained in the search image and the reference point attached to the object being measured, making it easy to determine whether the two match or not.

[0029] The device for managing dimensional information according to the fifth embodiment is the device for managing dimensional information according to any one of the first to fourth embodiments, wherein the matching unit matches the search information with the design information by using dimensional information relating to the embedded object.

[0030] Consequently, the position and size of the embedded object can be compared using the dimensions (width) in the scanning direction of the embedded object contained in the search information and the dimensional information about the embedded object contained in the design information, making it easy to determine whether the two match or not.

[0031] The device for managing dimensional information according to the sixth embodiment is the device for managing dimensional information according to one of the first to fourth embodiments, wherein the matching unit matches the search information with the design information by subjecting the search image containing the embedded object to a pattern comparison with drawings contained in the design information.

[0032] Consequently, the search image containing the embedded object and included in the search information, and the drawing included in the design information, are subjected to a pattern matching process, and the position and size of the embedded object are compared, making it easy to determine whether or not a match exists.

[0033] The device for managing dimensional information according to one of the first to sixth embodiments further comprises a design drawing generation unit which, based on the search information and the corresponding design information, generates a design drawing with screw positions if, as a result of the matching performed by the matching unit, the search information matches the design information.

[0034] In this case, the design drawing generated by the design drawing generation unit specifies, in a drawing showing the position of the embedded object in the measured object, which has been determined to be essentially the same as in the search information, for example, the positions where screws or other such design materials are to be installed, in relation to the embedded object, which is the object of the design.

[0035] Consequently, a design drawing generated by matching search information and design information can be used to perform design work in relation to the embedded object on an actual measurement object.

[0036] The device for managing dimensional information according to the seventh embodiment is the device for managing dimensional information according to the second embodiment, wherein the first display control unit controls the first display unit in such a way that it displays a design drawing in which design information, including position information for the embedded object in the measured object, is reproduced in the search information.

[0037] Consequently, a worker can look at the display screen of the first display unit, which shows a construction drawing in which the construction information is reproduced in the search image, and can carry out the construction work without having to mark the object being measured (the wall surface, etc.).

[0038] The device for managing dimensional information according to the eighth embodiment is the device for managing dimensional information according to one of the embodiments one to seven, wherein the design information includes information about at least one of the following: the name and dimensions of the embedded object that is the measurement object, and the position, type, spacing and number of screws to be used.

[0039] Consequently, design information, including the name and dimensions of the embedded object on which the design is to be carried out, the position, type, spacing and number of screws to be installed, etc., can be used for matching with the search image, and this information can be reproduced in the search image.

[0040] The system for managing dimensional information according to the ninth embodiment comprises the device for managing dimensional information according to one of embodiments one to eight and a device for scanning embedded objects, which has a data transmission unit that transmits a search image to the acquisition unit of the device for managing dimensional information.

[0041] Consequently, a search image can be stored as search information in the device for managing dimensional information, which the search image has received from the data transmission unit of the device for scanning embedded objects.

[0042] The system for managing dimensional information according to the tenth embodiment is the system for managing dimensional information according to the ninth embodiment, wherein the device for scanning embedded objects comprises: a detection unit that detects the presence or absence of the embedded object, a search image conversion processing unit that converts the detection result from the detection unit into the search image, a storage unit that stores the search image and a grid plane comprising grid lines corresponding to a predetermined scale, and a second display unit that displays the search image and the grid plane.

[0043] Consequently, in a device for scanning embedded objects that detects embedded objects, such as wood and reinforcing steel, in a measurement object, such as a wall or concrete, a search image, which is converted from the detection result in the detection unit, and a grid plane, which includes grid lines, can be displayed on the second display unit in a state in which they are superimposed.

[0044] The system for managing dimensional information according to the eleventh embodiment is the system for managing dimensional information according to the tenth embodiment, wherein the device for scanning embedded objects further comprises: an operator input unit into which various operator operations are entered, and a second display control unit which controls the second display unit such that the search image and the grid plane are superimposed and the search image is displayed in a state in which it can move relative to the grid plane in response to an input into the operator input unit.

[0045] Consequently, in a device for scanning embedded objects, a search image can be displayed in a state in which it can be moved relative to the grid plane in response to an input into the operator input unit.

[0046] Therefore, the distance between the grid lines can be checked by moving the search image and the grid plane relative to each other in such a way that the position serving as the reference point is aligned with the grid lines, for example, making it easy to check the distance from the position serving as the reference point to the position of the embedded object on the display screen of the display unit without having to place any markings on the wall surface.

[0047] Consequently, no marking work is required during a search for embedded objects, and the workload of the worker can be reduced.

[0048] The method for managing dimensional information according to the twelfth embodiment is a method for managing dimensional information about an embedded object contained in a search image that indicates the presence or absence of the embedded object in a measurement object and is generated by an embedded object scanning device that performs a scan along the measurement object, wherein the method comprises a capture step and a search information storage step. The capture step comprises capturing search information comprising the search image from the embedded object scanning device. The search information storage step comprises storing the search information captured in the capture step.

[0049] In a method for managing dimensional information, which manages dimensional information about embedded objects by capturing a search image showing the presence or absence of an embedded object from a device for scanning embedded objects that performs scanning on the surface of a measurement object, such as a wall surface or concrete, to detect the embedded objects, such as wood and metal, contained in the measurement object, information comprising the search image captured in the sensing step is stored as search information about the embedded object.

[0050] In a method for managing dimension information, for example, a personal computer (PC) used by a manager who manages a construction site, or a smartphone, tablet device or the like owned by a worker, is used as a device for managing dimension information.

[0051] The search information acquired by the device for scanning embedded objects includes, for example, a search image, dimensional (width) information in the scanning direction of the embedded object contained in the search image, and information such as the distance from the scanning start point (reference point) to an embedded object and the distance between embedded objects.

[0052] Consequently, search information stored in the step for saving search images can be used, and the search information can be displayed, for example, on the display device, making it possible to determine the position and size of the embedded object without the need to make markers during the design work.

[0053] Furthermore, based on the search information stored in the step for saving search images, a construction drawing can be generated that shows the position of an embedded object in the measured object and the installation positions of screws or the like.

[0054] Consequently, the design work can be carried out based on the position and size of embedded objects contained in the object being measured, thus reducing the worker's workload.

[0055] The method according to the twelfth embodiment further comprises an input step with receiving input of design information, which includes position information about the embedded object in the measurement object; a matching step with comparing the stored search information with the input design information and determining whether there is a match or not; and a design drawing generation step with generating, based on the search information and the corresponding design information, a design drawing with screw positions if, as a result of the matching, the search information matches the design information.

[0056] The program for managing dimensional information according to the thirteenth embodiment causes a computer to execute a method for managing dimensional information that manages dimensional information about an embedded object contained in a search image. This image represents the presence or absence of the embedded object in a measurement object and is generated by an embedded object scanning device that performs a scan along the measurement object. The method comprises a capture step and a search information storage step. In the capture step, search information comprising search images is captured by the embedded object scanning device. In the search information storage step, the search information captured in the capture step is stored.

[0057] In a program for managing dimensional information, which manages dimensional information about an embedded object by capturing a search image showing the presence or absence of an embedded object from a device for scanning embedded objects, which performs a scan on the surface of a measurement object, such as a wall surface or concrete, to detect the embedded objects, such as wood and metal, contained in the measurement object, the information comprising search images captured in the acquisition step is stored as search information about the embedded object.

[0058] In a method for managing dimension information, for example, a personal computer (PC) used by a manager who manages a construction site, or a smartphone, tablet device or the like owned by a worker, is used as a device for managing dimension information.

[0059] The search information acquired by the device for scanning embedded objects includes, for example, search images as well as dimensional (width) information in the scanning direction of the embedded object contained in the search image, and information such as the distance from the scanning start point (reference point) to the embedded object and the distance between embedded objects.

[0060] Consequently, the position, size, and so on of an embedded object can be determined without the need for marking work during construction, for example by using the search information stored in the search image storage unit and displaying the search information on the display device.

[0061] Furthermore, based on the search information stored in the step for saving search images, a construction drawing can be created that shows the position of the embedded object in the measured object, screw positions and other such construction positions.

[0062] Consequently, the design work can be carried out based on the position, size, and so on of embedded objects contained in the object being measured, which reduces the workload on the workers.

FORMS OF EXECUTION OF THE INVENTION

[0065] System 1 for managing dimensional information, which includes device 40 for managing dimensional information according to an exemplary embodiment, is now described with reference to the Fig. 1 to Fig. 33 described. (1) Configuration of System 1 for managing dimension information

[0066] As in Fig. As shown in Figure 1, the system 1 for managing dimensional information according to this embodiment comprises a device 10 for scanning embedded (or hidden) objects and a device 40 for managing dimensional information (see Figure 1). Fig. 3, Fig. 25, etc.).

[0067] The device 10 for scanning embedded objects moves along a wall surface (measurement object) 50 while detecting capacitance changes with a capacitance sensor 13 (see Fig. 3; discussed below) detected, thereby detecting embedded objects 51 such as wood (columns 51a and pins 51b), metal or the like contained in the wall surface 50.

[0068] As in Fig. As shown in Figure 3, the device 40 for managing dimensional information is able to communicate with the device 10 for scanning embedded objects, receives search information about the embedded object 51 in the wall surface 50 from the device 10 for scanning embedded objects, and manages dimensional information, such as the position and size of the embedded object 51. (2) Configuration of the device 10 for scanning embedded objects

[0069] As in Fig. As shown in Figure 2, the device 10 for scanning embedded objects comprises a main body 11, a display unit (second display unit) 12, a capacitance sensor 13 (see Figure 2). Fig. 3), an optical sensor 14 (see Fig. 3) and an operating input unit 15.

[0070] The wall surface 50 comprises, for example, wallpaper or other such decorative material applied to a drywall or plywood surface. The embedded object 51 comprises, for example, columns, beams, struts, and other such wooden or metal frames.

[0071] As in Fig. As shown in Figure 2, the main body 11 is a plastic element having an essentially cuboid shape, and the display unit 12 and the operating input unit 15 are located on the side (front) facing the user during use. The capacitance sensor 13 and the optical sensor 14 are located on the side (rear) facing the wall surface 50 (the side opposite the user).

[0072] Recesses 11a are provided on the upper end face and the left and right end faces of the main body 11. The recesses 11a are used, for example, to mark the scanning start point on the wall surface 50 with a pen or the like when the wall surface 50 is scanned with the device for scanning embedded objects 10.

[0073] As in Fig. As shown in Figure 2, the display unit 12 is, for example, a liquid crystal display device and is arranged on the front of the main body 11. The display unit 12 shows, for example, the settings of the device for scanning embedded objects 10, a search image showing the detection result of the embedded object 51, and so on, and what is displayed is switched according to the operating operation entered into the operating input unit 15.

[0074] The capacitance sensor 13 is located on the back of the main body 11 and is a sensor that detects changes in capacitance when the device for scanning embedded objects 10 performs a movement along the wall surface 50, and is used to detect an embedded object 51 that is located within the wall surface 50.

[0075] The optical sensor 14 is located on the back of the main body 11 and receives reflected infrared light emitted onto the wall surface 50 to, for example, capture position information via the device 10 for scanning embedded objects.

[0076] As in Fig. As shown in Figure 2, the operating input unit 15 is located on the front of the main body 11. The operating input unit 15 comprises a power button 15a, a grid display button 15b, a scale toggle button 15c, a D-pad (directional pad or arrow keypad) 15d, and an enter button 15e.

[0077] The power button 15a is located on the upper right side of the operating input unit 15. Pressing and holding this button downwards, for example, switches the power supply of the device 10 for scanning embedded objects on or off.

[0078] The grid display button 15b is located on the upper left side of the operating input unit 15 and is pressed when a grid plane, in which several grid lines (discussed below) are arranged in a grid pattern, is superimposed on the search image on the display screen 12a of the display unit 12. If the grid display button 15b is pressed again in a state where the grid plane is superimposed on the search image and displayed on the display screen 12a, a measurement grid (grid lines) is also displayed on the display screen 12a.

[0079] The scale toggle button 15c is located in the upper middle part of the operating input unit 15 and is pressed, for example, when the superimposed display of the search image and the grid plane is enlarged.

[0080] The D-pad 15d is located at the bottom of the operator input unit 15 and allows input of operations in four directions: up, down, left, and right. For example, if the D-pad 15d is moved up, down, left, or right while the grid plane containing the grid lines is superimposed on the search image, the search image will be moved relative to the grid plane.

[0081] The Enter key 15e is located in the middle position of the D-pad 15d and is pressed, for example, when a command selected using the D-pad 15d or the like is executed.

[0082] Furthermore, the device includes 10 for scanning embedded objects, as in Fig. Figure 3 shows a capacity acquisition unit 20, a position information acquisition unit 21, a storage unit 22, a determination unit 23 for the presence of embedded objects, a size calculation processing unit 24, a search image conversion processing unit 25, a unit 26 for estimating embedded objects, an input reception unit 27, a search image retrieval unit 28, a data transmission unit 29 and a display control unit 30, all of which are provided within the main body 11.

[0083] The capacity acquisition unit 20, the position information acquisition unit 21, the storage unit 22, the determination unit 23 for the presence of embedded objects, the size calculation processing unit 24, the search image conversion processing unit 25, the object estimation unit 26, the input reception unit 27, the search image retrieval unit 28, the data transmission unit 29 and the display control unit 30, which are provided within the device 10 for scanning embedded objects, are generated when the CPU reads various control programs stored in memory.

[0084] The capacity sensing unit 20 detects the output from the capacity sensor 13, which is located on the back of the main body 11, and transmits this output to the storage unit 22.

[0085] More precisely, the capacity sensing unit 20 detects capacity changes to determine whether the embedded object 51 is present within the range of motion each time the embedded object scanning device 10 has traveled a certain amount of distance along the wall surface 50, using the position information acquired by the position information sensing unit 21. Consequently, the search image conversion processing unit 25 (discussed below) can generate a search image for each specified amount of distance traveled within the range of motion using the output results from the capacity sensor 13.

[0086] The position information acquisition unit 21 acquires the output from the optical sensor 14, which is located on the rear of the main body 11, and transmits this output to the storage unit 22. Consequently, the device for scanning embedded objects 10 can acquire the position on the wall surface 50 and the amount of movement based on the position information acquired by the position information acquisition unit 21.

[0087] Storage unit 22 stores the capacity data received from capacity acquisition unit 20, the position information data received from position information acquisition unit 21, and a table of embedded objects (see Fig. 11), which includes information about the size of embedded objects 51 in the scanning direction of the embedded object scanning device 10, search images converted from the capacity data in the search image conversion processing unit 25, a grid plane superimposed with a search image, a reference point display plane, and the like. The storage unit 22 transmits a search image, retrieved by the search image retrieval unit 28, etc., to the data transmission unit 29 and the display control unit 30.

[0088] The search images stored in memory unit 22, along with information about the time at which the wall surface 50 was scanned, are stored in a state where they are grouped into units of a scan. In this embodiment, search images corresponding to multiple scans are stored in memory unit 22.

[0089] Furthermore, search images that have been converted for each specific amount of movement are accumulated and stored after the power supply to the device 10 for scanning embedded objects has been switched on, and multiple search images are stored in a state in which they are grouped into units of a single scan.

[0090] Unit 23 for determining the presence of embedded objects determines whether an embedded object 51 is present in the wall surface 50 (edge ​​detection processing) based on whether the output signal (capacitance data) of the capacitance sensor 13 has exceeded a certain threshold. This makes it possible to determine, based on the output result of the capacitance sensor 13, whether an embedded object 51 is present.

[0091] The size calculation processing unit 24 calculates an estimate of the size (width, etc.) of the embedded object 51 in the wall area 50 based on the output signal (capacitance data) of the capacitance sensor 13. More precisely, the size calculation processing unit 24 detects the edge segments at both ends where the output signal of the capacitance sensor 13 has changed and calculates the estimated size based on the space between the edges, which is assumed to be the embedded object 51.

[0092] The search image conversion processing unit 25 converts the output signal of the capacitance sensor 13 into a search image that indicates the presence or absence of an embedded object 51. More precisely, based on the position information for the embedded object scanning device 10, which is acquired by the aforementioned position information acquisition unit 21, the search image conversion processing unit 25 generates a search image by using the capacitance data that is acquired each time the movement of the embedded object scanning device 10 along the wall surface 50 reaches a certain distance.

[0093] The estimation unit 26 for embedded objects compares the estimated size (width) of the embedded object 51 in the scanning direction, calculated by the size calculation processing unit 24, with the width of each type of embedded object 51 listed in the table of embedded objects (see Fig. 11) is contained in the storage unit 22 and estimates the corresponding type of the embedded object 51.

[0094] The input receiving unit 27 receives user operations entered into the operating input unit 15, including the aforementioned power button 15a, grid display button 15b, scale toggle button 15c, D-pad 15d, etc.

[0095] For example, the search image retrieval unit 28 retrieves a search image stored in the memory unit 22 based on the user operation entered into the operating input unit 15, and transmits this image to the data transmission unit 29 or the display control unit 30.

[0096] The display control unit 30 can control the display unit 12 in such a way that, after a search image has been stored in the memory unit 22, the search image is displayed in real time during scanning, regardless of the operation entered by the user into the operating input unit 15.

[0097] As in Fig. As shown in Figure 3, the data transmission unit 29 transmits search images, the detection result for an embedded object 51 and other such search information to the device 40 for managing dimensional information, such as a smartphone or the like, owned by a worker, etc.

[0098] Fig. Figure 3 shows that the search information is transferred from the data transmission unit 29 of the device 10 for scanning embedded objects to the device 40 for managing individual dimension information, but there can also be several devices 40 for managing dimension information to which search information is transferred from the data transmission unit 29 of the device 10 for scanning embedded objects.

[0099] The display control unit 30 causes the display screen 12a of the display unit 12 to display a search image (see Fig. 4 etc.) to display the search image, which indicates the presence or absence of an embedded object 51 and, as described above, was generated by the search image conversion processing unit 25. In addition, the display control unit 30 causes the display screen 12a of the display unit 12 to display the search image, which is superimposed with the grid plane and the reference point display plane stored in the memory unit 22.

[0100] In a search image, as in Fig. Figure 4 shows several search images generated from the capacity data acquired along the path of the device 10 for scanning embedded objects, which performs a scan along the wall surface 50, combined to indicate whether an embedded object 51 is present or not.

[0101] As in Fig. As shown in Figure 3, the display control unit 30 also includes a grid display processing unit 31, a search image display processing unit 32 and an origin display processing unit 33.

[0102] The grid display processing unit 31 performs display processing such that a grid plane containing several grid lines, or a grid plane containing a measuring grid (grid lines) prepared to display the size of the embedded object 51, the distance to the embedded object 51, and so on in an easily understandable way, is superimposed on the search image.

[0103] The search image display processing unit 32 performs scroll processing to move the search image relative to the grid plane (fixed display) on the display screen 12a of the display unit 12, and displays on the display screen 12a the size of the embedded object 51 contained in the search image. In addition, the search image display processing unit 32 performs processing to toggle the display scale of the search image shown on the display screen 12a.

[0104] The origin display processing unit 33 performs processing to display a reference point P1 on the grid plane, which is superimposed with the search image on the display screen 12a.

[0105] The grid plane is a display plane (see Fig. 20A etc.), which contains several grid lines arranged in a grid pattern, and is superimposed on a search image that shows whether an embedded object 51 is present or not. The display control unit 30 causes the display unit 12 to display the search image in a state where it is movable with respect to the grid plane.

[0106] In the reference point display plane, for example, the reference point P1 (see Fig. 18 etc.), which indicates the scanning start point, is displayed on the display screen 12a of the display unit 12, which is superimposed on the search image and the grid plane. The reference point display plane is superimposed on the search image and the grid plane in a state in which it can be moved relative to the grid plane (fixed display), similar to the search image (see Fig. 20B).

[0107] The display control of the display unit 12 by the display control unit 30 is described in detail below. From the creation to the storage of search images

[0108] With the device 10 for scanning embedded objects of the present embodiment, the wall surface 50 is scanned with the above configuration, and as a result a search image is generated that indicates the presence or absence of an embedded object 51 in the wall surface 50, based on the capacity change thus obtained.

[0109] The following is an example using the flowchart in Fig. 5 describes the processing for creating a search image.

[0110] In step S11, the capacity measurement unit 20 records the capacity measured by the capacity sensor 13.

[0111] Next, in step S12, the position information acquisition unit 21 acquires the position information about the device 10 for scanning embedded objects, which is measured by the optical sensor 14.

[0112] Next, in step S13, the position information about the device 10 for scanning embedded objects, which is acquired by the position information acquisition unit 21, is used to determine whether the device 10 for scanning embedded objects has moved along the wall surface 50 or not. If it is determined that the device has moved, the processing continues with step S14, and if it is determined that the device has not moved, step S13 is repeated until it is determined that the device has moved.

[0113] Next, since it was determined in step S13 that the device 10 for scanning embedded objects has moved, in step S14 the coordinates (relative coordinates) that indicate the current position of the device 10 for scanning embedded objects are calculated and recorded.

[0114] Next, in step S15, the coordinates of the current position of the device 10 for scanning embedded objects, which were calculated and recorded in step S14, are calculated and recorded as relative coordinates, and the processing proceeds to step S16.

[0115] Consequently, for example, each time the position information acquisition unit 21 detects that the position of the device 10 for scanning embedded objects, detected by the optical sensor 14, has reached a certain amount of movement, the capacity data acquired by the capacity acquisition unit 20 can be stored.

[0116] Next, in step S16, unit 23 performs processing to determine the presence of embedded objects, based on the captured capacity data, whether an embedded object 51 is present in the sampling area or not.

[0117] Next, in step S17, the presence detection unit 23 determines whether an embedded object 51 is present or not, and if one is present, processing continues with step S18, and if not, processing continues with step S19.

[0118] Next, in step S18, the size calculation processing unit 24 calculates the estimated size (width) of the embedded object 51 in the scanning direction of the device 10 for scanning embedded objects, since it was determined in step S17 that an embedded object 51 is present.

[0119] Next, in step S19, the search image conversion processing unit 25 performs processing to convert the capacity data acquired by the capacity acquisition unit 20 into a search image, regardless of the presence or absence of an embedded object 51.

[0120] Next, in step S20, the search image created in step S19 is stored in memory unit 22.

[0121] In the present embodiment, a search image is generated in the steps described above using the capacity data measured by the capacity sensor 13 and stored in the storage unit 22. From the start of scanning to the storage of images

[0122] Next, the steps from the start of scanning along the wall surface 50 to the memory processing of the search image in the device 10 for scanning embedded objects of the present embodiment are described using the flowcharts in the Fig. 6 to Fig. 10 described. (a) Coordinate acquisition processing

[0123] Referring to the flowchart in Fig. 6 will now handle coordinate acquisition processing in S14 from Fig. 5, which is carried out by the device 10 for scanning embedded objects in this embodiment, is described in detail.

[0124] In the present embodiment, when scanning along the wall surface 50 is started with the device 10 for scanning embedded objects, the position information measured by the optical sensor 14 is recorded in step S21 as a coordinate change amount (X, Y), as shown in Fig. 6 shown.

[0125] Next, in step S22, the coordinate change amount recorded in step S21 is added to the cumulative coordinates.

[0126] Next, in step S23, the cumulative coordinates obtained in step S22 are set as the current position of the device 10 for scanning embedded objects. (b) Processing to determine the presence of embedded objects

[0127] The processing to determine the presence of an embedded object 51 in S17 of Fig. 5, which is carried out by the device 10 for scanning embedded objects in this embodiment, is now described with reference to the flowchart of Fig. 7 described in detail.

[0128] First, in step S31, the change in the recorded result of the capacity, measured by the capacity sensor 13, is calculated as the determining value.

[0129] Next, in step S32, it is determined whether the determined value is equal to or greater than a specific threshold. If the determined value is equal to or greater than the specific threshold, processing continues with step S33; otherwise, processing continues with step S34.

[0130] Next, in step S33, since it was determined in step S32 that the determined value is equal to or greater than a specific threshold, it is determined that an embedded object 51 is present in the sampling area, and the processing ends.

[0131] On the other hand, in step S34, since it was determined in step S32 that the determined value is less than the specific threshold, it is determined that there is no embedded object 51 in the sampling area, and the processing ends. (c) Processing for estimating embedded objects

[0132] Referring to the flowchart in Fig. 8 will now process the estimation of the embedded object 51 in S18 from Fig. 5, which is carried out by the device 10 for scanning embedded objects in this embodiment, is described in detail.

[0133] First, in step S41, the continuous width (length) of the embedded object 51 in the scanning direction before and after the current position of the device 10 for scanning embedded objects from the in Fig. The table shown in section 12 is used to store the recorded data.

[0134] This includes, as in Fig. Figure 12 shows the table for storing recorded data, including information about the recording time, the coordinates (X, Y), the measured result from the capacitance sensor, the result of determining an embedded object, the type of embedded object, and the size.

[0135] The type of embedded object that is in the Fig. The data contained in the table shown in section 12 for storing captured data is captured as follows. Information about the name, width, and thickness for each of the items in the table is used to store the captured data. Fig. 11 types of embedded objects 51 shown, reference is made to the width, this width is compared with the estimated size of the detected embedded object, and the result is the estimated type of embedded object 51.

[0136] Then, in the processing of steps S42 to S46, the focus shifts to the... Fig. Reference is made to the table shown for embedded objects (S43), and the material (sill, passage column, upright column, tenon, beam, strut, girder, decorative molding, etc.) that matches the continuous width (length) of the embedded object 51 in the scanning direction, as captured in step S41, is repeatedly checked a number of times that corresponds to the number of materials (S44).

[0137] If the width is substantially the same as that of one of the embedded objects 51 contained in the embedded objects table, processing continues in step S44 with step S46, and the type of the embedded object 51 is estimated. Then the embedded objects table is returned to reflect the estimation result, and processing ends.

[0138] On the other hand, if in step S44 the width is not the same as that of one of the embedded objects 51 contained in the table of embedded objects, the processing of steps S42 to S46 is repeated until all types in the table of embedded objects have been checked, and the processing is terminated. (d) Search image conversion processing

[0139] Referring to the flowchart of Fig. Section 9 now describes in detail the search image conversion processing in S19. Fig. 5 described, which is carried out by the device 10 for scanning embedded objects in this embodiment.

[0140] First, in step S51, the amount of change (determined value) of the recorded result from the capacity sensor, which in step S31 is entered in Fig. The processing shown in step 7, used to determine the presence of embedded objects, is calculated and converted into a brightness gradation of 255.

[0141] Next, in step S52, a search image is generated by drawing in the display buffer area with the converted brightness at the position coordinates specified in the Fig. The table shown in section 12 contains information on storing recorded data.

[0142] As in Fig. As shown in Figure 13, the coordinates (X, Y) and the corresponding values ​​for R (red), G (green) and B (blue) are stored in the display buffer area.

[0143] Next, in step S53, it is determined whether the size of the embedded object 51 could be determined or not. If the size could be determined, processing continues with step S54; if the size could not be determined, processing ends.

[0144] Next, in step S54, the embedded object 51, whose size has been determined, and its size (in the scanning direction) are entered into the Fig. The data collected is saved in the table shown in section 12, and processing is terminated. (e) Search image storage processing

[0145] Referring to the flowchart in Fig. Section 10 below details the search image storage processing in S20. Fig. 5 described, which is carried out by the device 10 for scanning embedded objects in this embodiment.

[0146] The first step in S61 determines whether an image deletion operation has been received or not, such as the user pressing the search start button.

[0147] If an image deletion operation was received, processing continues with step S62; otherwise, processing ends at this point.

[0148] Next, in step S62, the search image is placed in the display buffer area, which is located in Fig. 13 is shown, registered in the search image memory table, which is in Fig. 14 is shown before the screen is cleared.

[0149] As in Fig. As shown in Figure 14, the search image memory table is stored in a state where the date and time the search image was created and the image data ID attached to each search image are correlated. The search images stored in the search image memory table are each stored as image data corresponding to an operation.

[0150] Next, in step S63, the display buffer area is cleared, and processing ends.

[0151] Display control method of device 10 for scanning embedded objects. The following is described using the... Fig. 15 to Fig. 24 describes the display control method of the device 10 for scanning embedded objects in this embodiment. (a) Startup and preparation

[0152] First, as in Fig. As shown in Figure 15, in step S72, when the user presses (depresses) the power button 15a in step S71, the display control unit 30 displays a start screen on the display screen 12a of the device 10 for scanning embedded objects.

[0153] Next, in step S73, the display control unit 30 causes the display screen 12a of the device 10 to scan embedded objects, to display the initial search screen following the start screen.

[0154] The initial search screen, for example, is a screen (a screen view) that displays a square in the center of the display screen 12a, as in Fig. 16 shown.

[0155] Next, in step S74, in a state where the back of the main body 11 of the activated device 10 for scanning embedded objects is pressed against the construction surface (wall surface 50) to be scanned, the user inserts a pen or the like into the recess 11a and marks the wall surface 50 with a reference point P1, which serves as the scanning start point, thus setting the initial position at the beginning of the scanning. (b) Search scan

[0156] Next, the user moves, as in Fig. Figure 17 shows the device 10 for scanning embedded objects along the wall surface 50 in step S75 in order to perform a scanning along the construction surface.

[0157] Next, in step S76, the display control unit 30 (search image display processing unit 32, origin display processing unit 33) displays a reference point display plane comprising a search image that shows the search result over the scanning area and a reference point P1 on the display screen 12a of the device 10 for scanning embedded objects.

[0158] As in Fig. As shown in Figure 18A, this search screen displays an area A1 that was scanned by the device 10 for scanning embedded objects, detection areas S1 and S2 that indicate the embedded object 51 in the scanning area A1, and the reference point P1 where the scanning was started.

[0159] Next, in step S77, the user continues to scan the wall surface 50 with the device 10 for scanning embedded objects.

[0160] Next, in step S78, when search data is accumulated by further scanning in step S77, the display control unit 30 (search image display processing unit 32) causes the calculated size (width) (6 cm, 3 cm) of the detected embedded object 51 to be displayed on the search image in the scanning direction, as shown in Fig. 18B shown. (c) Operating procedure for displaying and aligning grids

[0161] Next, the user moves, as in Fig. Figure 19 shows that in step S79, after a scan is completed, the device 10 for scanning embedded objects moves away from the wall surface 50 and presses the grid display button 15b. If the grid display button 15b has already been pressed, a scan can be performed using the displayed grid plane.

[0162] Next, step S80 shows how to... Fig. As shown in Figure 20A, the display control unit 30 (grid display processing unit 31) on the search image overlays a grid plane containing several grid lines G1 arranged in a grid pattern on the display screen 12a of the display unit 12.

[0163] If the user then, in step S81, moves the D-pad 15d up, down, left or right on the screen Fig. When operating the display screen 12a shown in 20A, the search image and the reference point display plane, which contains the reference point P1, move relative to the grid plane, which contains the grid lines G1 (fixed display).

[0164] If the user then operates the D-pad in step S82 so that the position of reference point P1 corresponds to a specific position of the guide lines, the position of reference point P1 can be aligned with a specific position of the grid lines contained in the grid plane, as shown in Fig. 20B shown.

[0165] Consequently, the position (distance) of the embedded object 51 from the reference point P1, the shape of the embedded object 51, and so on, can be detected on the display screen 12a. (d) Distance and size of the embedded object based on the measuring grid

[0166] If the user proceeds next to step S83, as in Fig. As shown in Figure 21, pressing the grid display button 15b again causes the display control unit 30 (the grid display processing unit 31) to display the screen 12a as shown in Figure 21. Fig. 22A to display the measuring grid (the grid lines) G2.

[0167] As in Fig. As shown in Figure 22A, the displayed measuring grid G2 has a narrower spacing than the one shown in Figure 22A. Fig. 20A shows grid lines etc. so that the user can look at the display screen 12a and visually measure the size and distance from the reference point P1 of the embedded object 51.

[0168] Next, in step S84, when the user operates the D-pad 15d, the display control unit 30 (the search image display processing unit 32) moves the search image and the reference point display plane relative to the measuring grid G2 in order to accurately measure the distance between the reference point P1 and the embedded object 51 in a state where a grid plane encompassing the measuring grid G2 is displayed superimposed with the search image.

[0169] Assume the distance of the in Fig. For example, if the measuring grid G2 shown in 22A is 5 cm, the user can therefore see, when looking at the display screen 12a, that the distance from the reference point P1 to the detection area S1 is about 15 cm.

[0170] If the user next presses the scale toggle button 15c in step S85, the display control unit 30 (the search image display processing unit 32) displays the area defined by the dotted line in step S86. Fig. 22A is shown in an enlarged view, as in Fig. 22B shown.

[0171] Assume the distance of the in Fig. For example, if the measuring grid (grid lines) G3 shown in 22B is 1 cm, the user viewing the display screen 12a can measure the size more accurately and found that the width of the embedded object 51 in the detection area S1 is about 6 cm, the width of the embedded object 51 in the detection area S2 is about 3 cm, and the distance between the embedded objects 51 in the detection areas S1 and S2 is about 12 cm. (e) From design work to switching off

[0172] Next, based on the distance from reference point P1 to the embedded object 51, which is measured on display screen 12a through processing up to step S86, the user marks the first object in step S87, as shown in Fig. Figure 23 shows a position 15 cm in the horizontal direction away from the position marked as the reference point on the wall surface 50 as the position of the end section of the embedded object 51, in order to determine the actual position of the embedded object 51.

[0173] However, at this point, the marking can only be carried out at the construction position where an embedded object is present.

[0174] Next, in step S88, the user performs various construction operations, being aware of the position of the embedded object 51, which is marked on the wall surface 50.

[0175] This means that the user performs the work on the wall surface 50 (which he can mark if necessary) using the distance between the reference point P1 and the embedded object 51, the size of the embedded object 51, and the like, which are displayed on the display screen 12a, as shown in Fig. 24, showing the reference point P1, which is displayed on the display screen 12a of the device for scanning embedded objects 10, and the position of the embedded object 51 in the detection areas S1 and S2.

[0176] The user then presses the power button 15a to turn off the power supply, and the work is completed. (3) Configuration of device 40 for managing dimensional information

[0177] Device 40 for managing dimensional information is, for example, a smartphone or tablet device owned by a worker, a personal computer (PC) used by a manager, or the like, and features, as shown in Fig. Figure 25 shows a data receiving unit (acquisition unit) 41, a search information registration unit 42, a storage unit (search information storage unit) 43, an input unit 44, a design information registration unit 45, a search information retrieval unit 46, a matching unit 47, a design drawing generation unit 48, a display control unit (first display control unit) 49 and a display unit (first display unit) 49a.

[0178] As in Fig. As shown in Figure 26, the device 40 for managing dimensional information displays an image display area A2, in which a search image is displayed that is selected from the search information that is captured by the device 10 for scanning embedded objects, and a data selection area A3, which displays a list of search information that is registered in the memory unit 43, on the display screen of the display unit 49a of the smartphone or the like.

[0179] The data receiving unit (acquisition unit) 41 communicates with the data transmission unit 29 (see Fig. 3) the device 10 for scanning embedded objects and captures search information which includes the search images generated by the device 10 for scanning embedded objects.

[0180] The search information registration unit 42 registers (stores) the search information received by the device 10 for scanning embedded objects through the data receiving unit 41 in the search information registration database of the storage unit 43.

[0181] As in Fig. As shown in Figure 25, the storage unit (search information storage unit) 43 has a search information registration database in which the search information acquired by the device 10 for scanning embedded objects is registered, and a design information registration database in which design information entered by a worker or the like is registered.

[0182] The input unit 44 is, for example, a touch-sensitive screen or the like of the device 40 for managing dimensional information of the smartphone, etc., which is located in Fig. 26 is shown, and the design information is entered into this input unit by a worker or the like.

[0183] The design information registration unit 45 registers (stores) the design information entered into the input unit 44 in the design information registration database of the storage unit 43.

[0184] This includes, as in Fig. Figure 27A shows the design information entered by input unit 44, the name and width of the embedded object (pillar A), the strength (high, medium, low) of screws or the like used on the embedded object (pillar A), the number (1, 1, 2), the spacing (-, -, 15) and the size (M10, M8, M4) of the screws, etc., the positions of the screws and other such information.

[0185] As in Fig. As shown in Figure 27B, the position of the embedded object (pillar A) to be subjected to a construction, which is entered into input unit 44, is displayed as drawing ID:1.

[0186] Then, as in Fig. Figure 27C shows that the design information, which has been registered in the design information registration database of storage unit 43 by the design information registration unit 45, is stored, with the width of the embedded object (pillar A, B, C,...) and the strength, number, spacing, size, etc. of the screws or other such design materials being organized for each of the embedded objects. Consequently, a worker or the like can check the list of registered design information while looking at the display screen, which is shown, for example, on the display unit 49a of the device for managing dimensional information 40.

[0187] Then, as in Fig. Figure 28 shows the reference point P1, at which the scanning of the device for scanning an embedded object 10 is started, and the screw positions P2 are inserted into a drawing that shows the various embedded objects (pillars A, B, C,...) based on the design information contained in the list of Fig. 27C have been registered, and the resulting drawing is saved.

[0188] The reference point P1 is used as a reference point for comparison with the search image contained in the search information acquired by the device for scanning embedded objects 10.

[0189] Furthermore, the design information contained in Fig. Figure 28 shows a drawing which is prepared for carrying out a screw fastening work on the wall surface 50 at the positions of the objects 51 (pillars A, B, C, D) embedded in the wall surface 50.

[0190] The search information retrieval unit 46 retrieves the search information that is registered in the search information registration database of the storage unit 43 and transmits this information to the display control unit 49.

[0191] The matching unit 47 compares the search information received from the search information registration database of the storage unit 43 with the design information received from the corresponding design information registration database. The matching unit 47 then compares the search information and the design information at the corresponding positions and determines whether they match or not, that is, whether the positions of the embedded objects 51 in the search image, detected by the embedded object scanning device 10, match the positions of the embedded objects 51 in the drawing or not.

[0192] In particular, as in Fig. Figure 29 shows a drawing that compares the positions of the embedded objects (pillars A, B, C and D) obtained from the construction information of the upper drawing ID: 1 with the positions of the embedded objects in the search image captured as the lower search information.

[0193] Here, the comparison between the upper drawing and the lower search image is carried out using the reference point P1 mentioned above as a reference.

[0194] At this point, verification of whether the two match or not can be carried out using dimensional information, such as the distance from reference point P1 to each embedded object, the distance between embedded objects 51 or the width of an embedded object, or it can be carried out by a pattern matching between the drawing and the search image using reference point P1 as a reference.

[0195] When the matching unit 47 determines that the two match, the design drawing generation unit 48 generates a design drawing that reproduces design information, such as the screw position P2 in the search image that shows the position of the embedded object 51.

[0196] At the in Fig. The comparison shown in 29 can be seen, as in Fig. Figure 30 shows that the matching is carried out by combining several sections corresponding to different sets of search information 1, 2 and 3 to produce a single drawing of construction information.

[0197] Then, as in the Fig. 31A to Fig. Figure 31C shows the design drawing generation unit 48 producing a design drawing in which the screw position P2, which is contained in the design information drawing, is reproduced in the search images for the sets of search information 1 to 3.

[0198] The display control unit (first display control unit) 49 performs a control operation so that search information, design drawings, and the like are displayed on the display screen of the display unit 49a, which is located in Fig. 26 is shown.

[0199] The display unit (first display unit) 49a, in its function as a display device, shows search information, construction drawings and the like as a display device and is also used as the input unit 44 of the type of a touch-sensitive screen. Search Information Analysis Processing

[0200] With the device 40 for managing dimensional information of the present embodiment, search information is analyzed according to the flowchart shown in the above configuration. Fig. Figure 32 shows the search information acquired by the device 10 for scanning embedded objects.

[0201] That is, in step S101, the data receiving unit 41 of the device 40 for managing dimensional information receives the search information, which includes the search data and the search image, from the data transmission unit 29 of the device 10 for scanning embedded objects.

[0202] Next, in step S102, the search information registration unit 42 registers (stores) the search information received by the data receiving unit 41 in the search information registration database of the storage unit 43.

[0203] Next, in step S103, the search information retrieval unit 46 retrieves the search information registered in the storage unit 43 from the search information registration database.

[0204] Next, in step S104, the design information registration unit 45 registers (stores) the design information entered by the input unit 44 in the design information registration database of the storage unit 43.

[0205] Next, in step S105, the matching unit 47 compares the design information (drawings, etc.) that was registered in step S104 in the design information registration database of storage unit 43 with the search information (search images, etc.) that is registered in the search information storage database.

[0206] If, in step S106, the matching unit 47 determines that the two are substantially the same, processing continues with step S107. If, on the other hand, the matching unit 47 determines that the two are not the same, it is determined that the position of the embedded object 51, obtained from the search information, is offset from its actual position, and processing is terminated.

[0207] In this process, the matching in step S106 is performed by the matching unit 47, as described above, by comparing the dimensional information, such as the position, distance or the like, of the embedded object 51 using the reference point P1 as a reference, or by comparing a drawing and a search image by pattern matching, as discussed above.

[0208] Since the comparison by the comparison unit 47 in step S106 determined that the two are essentially identical, the next step in S107 is the design drawing generation unit 48 generating a design drawing in which the design procedure (design position, etc.) for the embedded object 51 contained in the design information is represented by the embedded object 51 of the search information (search image).

[0209] The aforementioned design procedure includes the design to be carried out, such as screwing the embedded object 51, the size of the screws used, and other such information.

[0210] Next, in step S108, the display control unit 49 controls the display unit 49a in such a way that it displays the design drawing that was generated by the design drawing generation unit 48.

[0211] Registration processing of design information. Next, with reference to the in Fig. The flow diagram shown in Figure 33 describes the flow of processing when the design information, which is entered by a worker or the like via the input unit 44, has been registered in the design information registration database of the storage unit 43 in the dimension information management device 40 of the present embodiment.

[0212] In step S111, the device 40 for managing dimensional information captures the design drawing information via the input unit 44.

[0213] Next, in step S112, based on the design drawing information captured in step S111, design information for a pillar or other such embedded object (the design target) is entered via input unit 44.

[0214] Next, in step S113, the design information registration unit 45 registers the design information, which includes the design drawing, in the design information management database of storage unit 43.

[0215] Step S114 then determines whether another drawing exists that needs to be included. If none exists, processing is terminated. Conversely, if another drawing exists that needs to be included, the processing of steps S111 to S114 is repeated until no further drawings need to be included. Further examples of implementation

[0216] An embodiment of the present invention has been described above, but the present invention is not limited to or restricted by the above embodiment, and various modifications are possible without departing from the core of the invention. (A)

[0217] In the description of the foregoing embodiment, an example was given in which the present invention was realized as the device 40 for managing dimensional information, as the system 1 for managing dimensional information comprising the device, and as a method for managing dimensional information, but the present invention is not limited thereto.

[0218] For example, the present invention can be implemented as a program for managing dimensional information which is suitable to cause a computer to execute the method for managing dimensional information described for the aforementioned device 40 for managing dimensional information.

[0219] The program for managing dimensional information is stored in memory (a storage unit) installed in the dimensional information management device. The CPU reads the dimensional information management program stored in memory and instructs the hardware to perform the various steps. Specifically, the same effect as described above can be achieved by having the CPU read the dimensional information management program, perform a capture step to capture search information, including search images, from the embedded object scanning device, and perform a search information storage step to store the search information captured in the capture step.

[0220] The present invention can also be implemented as a recording medium on which the program for managing dimensional information is stored, which is used by the device for managing dimensional information. (B)

[0221] In the description of the preceding embodiment, an example was given in which the device 40 for managing dimensional information of the present invention was provided as a device separate from the device 10 for scanning embedded objects, such as a smartphone, a tablet device, a PC used by a manager, etc., and which can communicate with the device 10 for scanning embedded objects, but the present invention is not limited thereto.

[0222] For example, the present invention can be implemented as a device for scanning embedded objects, which includes the functions of a device for managing dimensional information.

[0223] This means that the system for searching embedded objects of the present invention can be configured to be provided within a device for scanning embedded objects. (C)

[0224] In the description of the foregoing embodiment, an example was given in which the present invention was applied to a device 10 for scanning embedded objects of the capacitance type, in which the capacitance sensor 13 was used as the measuring unit, but the present invention is not limited thereto.

[0225] For example, the present invention can be applied to a device for scanning embedded objects of the electromagnetic wave type, which receives a reflected electromagnetic wave emitted in the direction of concrete or a wall material and measures the position of the embedded object. (D)

[0226] In the description of the foregoing embodiment, an example was given in which the optical sensor 14 was used as the scanning unit for measuring the amount of movement of the device 10 for scanning embedded objects along the wall surface, but the present invention is not limited thereto.

[0227] For example, the amount of movement of the device for scanning embedded objects along the wall surface can be measured using a scanning unit that employs something other than an optical method. (E)

[0228] In the preceding embodiment, an example was given in which the grid plane, comprising the grid lines, is displayed in a fixed display and the search image is moved so that the search image is displayed in a state in which it is movable relative to the grid plane. However, the present invention is not limited thereto.

[0229] For example, the search image can be displayed in a fixed state, and the grid plane can be displayed in a moving state.

[0230] Alternatively, both the search image and the grid plane can be displayed in a moving state if required. (F)

[0231] In the description of the foregoing embodiment, an example was given in which the device 10 for scanning embedded objects was used to detect a wood material (column, sill, beam, strut, etc.) contained (embedded) in a wall surface, such as a drywall or plywood, but the present invention is not limited thereto.

[0232] For example, the embedded object detected using the embedded object scanning device may be a different material than wood, such as metal or plastic.

[0233] Similarly, the object being measured can also be a material other than drywall, plywood, or another such wall surface, such as concrete.

[0234] This means that the device for scanning embedded objects of the present invention can, for example, also be used to detect other materials or foreign substances in the soil. (G)

[0235] In the description of the foregoing embodiment, an example was given in which the D-pad 15d was used to move the search image or reference point display plane relative to the fixed grid plane displayed on the display screen 12a of the display unit 12 of the device 10 for scanning embedded objects, but the present invention is not limited thereto.

[0236] For example, the device for scanning embedded objects can actually be moved across the wall surface, and the search image can be moved based on information about the amount of movement measured by an encoder, a tracking sensor, or the like.

[0237] Alternatively, a cursor can be used on a table to move the search image, for example, according to the time change on the key, e.g. by 1 mm the first time, by 2 mm the second time, and so on. (H)

[0238] In the description of the foregoing embodiment, an example was given in which three types of grid plane were used, namely the standard grid line G1, the measuring grid G3 and the measuring grid G3 for an enlarged display, but the present invention is not limited thereto.

[0239] For example, a grid plane is preferably used in which appropriately spaced grid lines are arranged according to the size (the size in the scanning direction) of the embedded object to be detected. (I)

[0240] In the description of the foregoing embodiment, an example was given in which the device 40 for managing dimensional information compares the search information, including a search image captured by the device 10 for scanning embedded objects, with the design information in order to generate a design drawing, but the present invention is not limited thereto.

[0241] For example, the device for managing dimensional information may have a key feature according to which the search information comprising the search image and acquired by the device for scanning embedded objects is used to display the search information on the display unit.

[0242] Alternatively, the device for managing dimensional information can generate design information by using search information that includes search images captured by the device for scanning embedded objects. (J)

[0243] In the description of the foregoing embodiment, an example was given in which the search image and the design information were used as a reference using the reference point P1, which indicates the scanning start point of the device 10 for scanning embedded objects, but the present invention is not limited to this.

[0244] For example, if scanning with the device for scanning embedded objects is started with reference to the edge of the wall surface, the position, etc., of the embedded object or the like can be aligned with reference to the edge of the wall surface without the need to provide a reference point. (K)

[0245] In the description of the foregoing embodiment, an example was given in which a mobile terminal, such as a smartphone, owned by a worker, was used as a device for managing dimensional information, but the present invention is not limited thereto.

[0246] For example, a PC (Personal Computer) used by a manager of the contractor performing the construction can be used as a device for managing dimensional information.

[0247] In this case, the manager can check the position of the embedded object and other such information while the search and construction information displayed on the PC is shown on the screen. Consequently, it is not necessary to mark the position of the detected embedded object on the wall surface, thus reducing the workload for the worker. (L)

[0248] In the description of the foregoing embodiment, an example was given in which search information comprising a search image is displayed on the display screen of the display unit 49a of the device 40 for managing dimensional information, but the present invention is not limited thereto.

[0249] For example, the grid plane, which includes several grid lines and is displayed in the device for scanning embedded objects, can also be overlaid with the search image on the device's display screen for managing dimensional information.

[0250] In this case, the position of the embedded object from the reference point, the distance between embedded objects, the width of the embedded object (dimension in the scanning direction), and so on can be easily determined by also referring to the grid lines on the display screen on the side of the device for managing dimensional information. COMMERCIAL APPLICABILITY

[0251] Since the device for managing dimensional information of the present invention enables the design work to be carried out on the basis of the position, size, and so on of an embedded object contained in the measuring object, it has the effect of reducing the workload of a worker and therefore finds a wide field of application in the form of different types of devices for managing search images that are captured using a device for scanning embedded objects.
