Description

The present invention relates to a thickness management system and a server of a covering material applied to a target portion such as a wall or floor of a building by a spraying method.

For the heat insulating material of a building, a worker uses a foaming machine at the site to directly apply a foamed stock solution containing a foaming material to the main raw material on the target surface such as the wall, floor, roof and ceiling of the building. Spray to foam and solidify. In the construction of such a heat insulating material, at the construction site, while spraying the heat insulating material, needle-shaped measuring gauges are pierced in various places of the foamed and solidified heat insulating material, and the thickness is measured to see if there is a predetermined thickness. We are checking each part to see if finishing is necessary.
Then, when reporting to the owner, etc. to guarantee the quality of the heat insulating material, the thickness read by inserting a measuring gauge into each part of the construction site is described in a predetermined report, or a mark related to the thickness (for example,). , The measured value of the thickness) is written on the surface of the heat insulating material (wall), and a photograph of a part or the whole of the surface of the heat insulating material including the description is presented.

On the other hand, after the heat insulating material is applied, the inner wall material is attached to the surface side of the heat insulating material, so that the heat insulating material is hidden by the inner wall. That is, the quality of the heat insulating material cannot be confirmed after the inner wall material is attached. Based on the above-mentioned report, the manager of the house maker or the like confirms the contents of the above-mentioned report, etc. from the time when the heat insulating material is installed until the inner wall material is attached.

In Patent Document 1, in order to solve the problem of schedule adjustment between the construction site and the evaluator by site inspection, etc., the terminal of the building material manufacturer, the terminal of the construction site, and the server holding the building material performance information database, etc. are connected. The network system is disclosed. Then, as a database stored in the server of the system, process management that records the construction history that manages the construction process, all the inspection items necessary for building construction, and the inspection history that displays the inspection method and inspection results. A database and a construction status database that records information including photographs of actual objects to be inspected in the construction process are listed. Further, in this system, it is proposed to automatically create an evaluation report such as a design housing performance evaluation application form from a database held in a server.

JP-A-2002-203067

However, the system of Patent Document 1 does not control the thickness of the heat insulating material or the quality of the heat insulating material.
In addition, as described above, detailed information is required to accurately grasp the quality of the heat insulating material, and the pin obtained by the installer or the inspector by piercing an arbitrary part of the heat insulating material with a measuring gauge as in the conventional case. Point thickness information is not sufficient.
That is, even if the conventional thickness information is recorded in the process control database of the system of Patent Document 1, the quality of the heat insulating material is not accurately controlled.
An object of the present invention is to provide a highly reliable structure thickness management system and server.

The thickness management system of the covering material of the present invention is based on a measuring means for measuring the three-dimensional data of the covering material applied by spraying on the construction target, and the three-dimensional data of the covering material or the three-dimensional data of the covering material.

It is preferable that the management system of the covering material of the present invention is provided with a proof means for certifying the construction result of the covering material based on the three-dimensional data of the covering material or the thickness data of the covering material.

In the structure management system of the present invention, it is preferable that the thickness data of the covering material is the total thickness data of the covering material.
Since it is possible to check the global and detailed thickness information of the entire covering material over the entire construction target instead of the conventional local thickness value of the covering material, it is easy for the viewer to understand and the reliability of the data is also high. high.

The covering material thickness management system 10 of FIG. 1 is a system that manages the thickness of the covering material applied by spraying on the construction target. Examples of the covering material include a heat insulating material, a fireproof material, a waterproof material, and a general building material (FRP, FRC, FRG) constructed by a spraying method. Particularly preferred is a foam-type hard urethane foam heat insulating material.
In the covering material thickness management system 10, the field terminal 100, the management terminal 200, and the server 300 are connected by a network 20. The covering material management system 10 stores and manages the covering material thickness data calculated based on the three-dimensional data of the covering material acquired by the field terminal 100 in the storage device 400 connected to the server 300. The thickness data of the covering material stored in the storage device 400 is browsed from the terminal 200.
The network 20 is constructed via a mobile phone network, a wireless LAN, an optical cable, or the like.

[Field terminal 100]
The field terminal 100 is information such as a computer having a control unit 110 including a CPU or the like, a storage unit (not shown), a display unit 120 such as a monitor, and an input unit (not shown) such as a keyboard or a mouse. It is a processing device. Further, a three-dimensional measuring device 150 is connected to the field terminal 100.
The control unit 110 is provided with a covering material thickness data creating means 111 and an automatic data transmitting means 112.
The field terminal 100 may be a dedicated information processing terminal that can be connected to the network 20, or a general-purpose notebook computer, tablet, smartphone, or the like that can be connected to the network 20 that is equipped with the necessary software. ..

In this embodiment, the thickness data of the covering material is calculated by the covering material thickness data creating means 111 of the field terminal 100 and the three-dimensional measuring device 150. Specifically, the three-dimensional measuring device 150 measures the three-dimensional data of the covering material, and the covering material thickness data creating means 111 calculates the covering material thickness data from the three-dimensional data of the covering material. Here, the "three-dimensional data of the covering material" includes data for specifying the three-dimensional shape of the covering material measured by an apparatus or the like, data for specifying the three-dimensional shape of the covering material by itself, and the like. To say.

The three-dimensional measuring device 150 is acquired by a three-dimensional measuring device such as a three-dimensional scanner or a stereo camera. A three-dimensional scanner irradiates a target surface with laser light and calculates the three-dimensional shape of the target surface based on the reflected light (so-called LIDAR method), and measures the distance by the time it takes for the irradiated light to be reflected and returned. There is something to measure (TOF method). On the other hand, the stereo camera calculates the three-dimensional shape from the images of the target surface captured by the two cameras based on the principle of triangular measurement, and is separately measured by a projector in order to improve the matching accuracy of the images of the two cameras. There is also a method of projecting a pattern or a method of replacing one of the two cameras with a projector that projects pattern light (so-called active stereo method). An appropriate device should be selected in consideration of measurement accuracy, measurement speed, and cost, but since the floor plan of the room with the target surface varies depending on the building, the accuracy is relatively stable in 3D of the LIDAR method. A scanner is preferred. On the other hand, considering the complexity of installing the scanner in the field, an active stereo type handy scanner capable of capturing a wide target surface at one time is preferable.

As shown in FIG. 2, the covering material thickness data creating means 111 has a construction shape including three-dimensional coordinates of the surface of the covering material and three or more reference three-dimensional coordinates of known and the same distance from the target surface. The acquisition process (first step), the calculation of the virtual plane (second step), the calculation of the thickness of the covering material (third step), and the covering material based on the thickness of the covering material. It has a step of displaying an image (fourth step).

In the first step, a construction shape including three-dimensional coordinates of the surface of the covering material and three or more reference three-dimensional coordinates having the same known distance from the target surface is acquired by a three-dimensional measuring device. In this embodiment, this construction shape becomes three-dimensional data of the covering material.
Here, for the reference three-dimensional coordinates of three or more points whose distances are known and the same from the target surface, for example, three or more reference markers are provided on the covering material so that the perpendiculars drawn on the target surface have the same length. The points on each reference marker are used as the reference three-dimensional coordinates. The construction shape 30 of FIGS. 3a and 3b includes the three-dimensional coordinates of the covering material 31 and the three-dimensional coordinates of the surface of the four reference markers 32. As shown in FIG. 3b, the reference marker 32 is provided by inserting the reference marker 32 having the pin 32a extending in one direction through the covering material 31 so that the tip of the pin 32a comes into contact with the target surface 35.
At the same time as the first step, the construction shape is stored in the storage unit of the site terminal 100 in a locked state so that it cannot be rewritten by anyone other than the manager who handles the management terminal 200 or a qualified person.

The reference three-dimensional coordinates of the first step are not particularly limited as long as the distance from the target surface is known. For example, the surface of a structure located adjacent to or near the target surface can be mentioned. As a structure, for example, a structure such as a pillar, a sash, a threshold, a peripheral edge, a secondary tree, or a beam material located in the same room as the wall surface of the target surface, or a floor, a ceiling, a wall boundary, a pipe, a door, and ventilation Examples thereof include structures having a characteristic shape such as an opening such as a mouth and a power distribution box. When the structure is used in this way, the distance to the target surface can be accurately grasped from the design drawing or the like, so that human error can be reduced.

The second step calculates a virtual plane. Specifically, based on the reference three-dimensional coordinates (reference marker 32), a virtual plane obtained by translating the target surface by a predetermined distance in the direction perpendicular to the target surface is calculated in the construction shape. FIG. 3c shows the virtual plane S calculated in the construction shape based on the four reference markers 32.
Specifically, first, four reference markers 32 are automatically recognized from the construction shapes based on the characteristics of the color and shape. For example, when a red reference marker is used, the red region can be recognized as a reference marker from the construction shape.
Next, three or more reference three-dimensional coordinates are extracted from the four recognized reference markers 32. For example, the coordinates of the center of gravity of each reference marker may be set as the reference three-dimensional coordinates. It is not always necessary to use all four reference markers, and a plurality of reference three-dimensional coordinates may be extracted from one reference marker. Next, the plane S1 is estimated based on the three or more reference three-dimensional coordinates extracted. At this time, it is expected that the reference three-dimensional coordinates will not be exactly on the same plane due to the influence of the measurement error of the three-dimensional measuring device 150, the inclination of the reference marker with respect to the target surface, and the like. Therefore, a plane may be fitted to a plurality of reference three-dimensional coordinates. Known techniques can be used for this. For example, the least squares method may be used to find the least squares plane for a plurality of reference three-dimensional coordinates. The plane S1 is parallel to the target surface 35 and is separated by a predetermined distance L (see FIG. 3b). The virtual plane S is calculated by expanding the plane S1 to a position and size in which the target plane is translated by a predetermined distance in the direction perpendicular to the target plane. The virtual plane S may be calculated at a position separated from the target surface 35 by a predetermined reference thickness. At this time, if the covering material 31 is constructed according to the reference thickness, the surface of the covering material coincides with the virtual plane S.
At the same time as the second step, this virtual plane is stored in the storage unit of the field terminal 100 in a locked state so that it cannot be rewritten by anyone other than the administrator who handles the management terminal 200 or a higher qualification.

In the third step, the thickness of the covering material is calculated. Specifically, in the construction shape for which the virtual plane is calculated, the thickness of the covering material is calculated based on the virtual plane calculated based on the three-dimensional coordinates of the surface of the covering material and the reference three-dimensional coordinates.
Specifically, the distances between the points on the surface of the covering material and the points on the virtual plane that intersect the vertical line with respect to the target surface are calculated, and the distance L on the virtual plane with respect to the target surface is taken into consideration to determine the points on the surface of the covering material. Calculate the thickness. That is, as shown in FIG. 3c, the distance between the point C1 on the surface of the covering material intersecting the vertical line V1 with respect to the target surface and the point T1 on the corresponding virtual plane is Z1, and the point C1 covers the virtual plane S. If so, the thickness of the point C1 of the covering material is L-Z1. On the other hand, when the distance between the point C2 on the surface of the covering material that intersects the vertical line with respect to the target surface and the point T2 on the corresponding virtual plane is Z2, and the point C2 protrudes from the virtual plane S, the point of the covering material. The thickness of C2 is L + Z2 (not shown). With this method, the thickness of the covering material in the entire region can be calculated. Such a calculation may be obtained by subtracting the point cloud coordinates of the surface of the covering material and the point cloud coordinates of the virtual surface, or the difference may be calculated by converting the point cloud into a mesh and calculating the faces. ..
At the same time as the third step, the thickness of the covering material is stored in the storage unit of the field terminal 100 in a locked state so that it cannot be rewritten by anyone other than the manager who handles the management terminal 200 or a higher qualification.

The fourth step displays the image of the covering material. More specifically, it is an image showing the surface of the covering material, and the covering material image showing the distribution of the thickness of the covering material in color or shading is calculated and displayed.
Examples of the image displaying the surface of the covering material include a perspective image expressed in three dimensions and a two-dimensional image in which the construction shape is projected on a predetermined plane (for example, a plane parallel to the target plane).
At the same time as the fourth step, the covering material image is also stored in the storage unit of the field terminal 100 in a locked state so that it cannot be rewritten by anyone other than the administrator who handles the management terminal 200 or a higher qualification.

In this way, the covering material thickness data creating means 111 approximately automatically performs the covering material thickness data and the covering material on the system without any human operation on the construction shape measured by the three-dimensional measuring device 150. Since it is converted to an image, there is no risk of human error and the data is highly reliable.

The data automatic transmission means 112 converts the covering material image (covering material thickness data) created by the covering material thickness data creating means 111 into non-editable (for example, locked by a password) data in the storage device 400 of the server 300. Automatically send to. As a result, it is possible to prevent unintended alteration of the data and store the thickness data of the covering material in the storage device 400 in a state of maintaining the objectivity.
In order to further enhance the objectivity of the data, the work start authentication means may be provided in the field terminal 100 and the server 300. For example, when the worker requests the start of measurement such as pressing the authentication button of the field terminal 100 when starting the measurement, the field terminal 100 requests the server 300 to authenticate. At this time, ID information that identifies the worker, position information that identifies the construction site, and the like may be added. The server 300 side determines whether the work may be started (measurement start) in response to the authentication request, and transmits the approval / disapproval result to the site terminal 100. The field terminal 100 operates the measurement function only when the approval is received. The work start authentication means may be performed by the management terminal 200 via the server 300. For example, the manager of the office may check the authentication request one by one and decide whether or not to approve it. When the server 300 automatically determines, it may be determined whether the construction is regular or not and the approval or disapproval may be transmitted by inquiring the ID information, the location information, etc. with the pre-registered construction schedule information. ..

As described above, in the field terminal 100, since the worker does not operate the terminal after starting the measurement, the work is easy for the worker and there is no risk of mistakes. Further, since the thickness data of the covering material is automatically transmitted to the storage device 400, it can be stored as highly objective data.
Data other than the thickness data of the covering material (for example, product information as described later) is input from the input unit of the field terminal 100 and stored in each database.

In this embodiment, the image of the covering material is given as the thickness data of the covering material in the fourth step, but a table relating the coordinates of the target surface calculated in the third step and the thickness of the covering material is used for the covering material. It may be used as thickness data. Further, the thickness data of the covering material does not represent the entire covering material, but may represent the coordinates of the covering material whose thickness is out of the predetermined range and the thickness thereof. The content of the thickness data of the covering material may be set according to the conditions to be satisfied. However, it is preferable that the thickness of the entire covering material is represented.

[Management terminal 200]
Returning to FIG. 1, the management terminal 200 includes a control unit (not shown) composed of a CPU or the like, a storage unit (not shown), a display unit such as a monitor (not shown), a keyboard, a mouse, or the like. It is an information processing device such as a computer having an input unit (not shown) or the like.
By connecting the management terminal 200 to the server 300, each database of the storage device 400 of the server 300 can be browsed.

[Server 300]
The server 300 is composed of an information processing device including a CPU and the like, and includes a thickness data storage means 301, an inspection means 302, a proof means 303, a data providing means 304, and an authentication means 305. ..

The thickness data storage means 301 receives a covering material image (covering material thickness data) from the site terminal 100, and stores the image in the covering material thickness database 401 described later.

In the inspection means 302, the covering material image (coating material thickness data) transmitted from the site terminal 100 or the covering material image (covering material thickness data) of the covering material thickness database 401 is a predetermined covering material. Inspect whether the conditions are met. Then, the inspection result is transmitted to the site terminal 100. In addition, the inspection result is converted into non-editable data and stored in the inspection history database 406, which will be described later.
In the inspection of the thickness data of the covering material, it is inspected whether the thickness of the covering material is within a predetermined range, and the part of the covering material that does not satisfy the predetermined condition is specified as a construction defective part. In addition, it is calculated how much the thickness of the poorly constructed covering material is out of the predetermined range. For example, when a covering material image is sent as the thickness data of the covering material, a special color is used for the part of the covering material that does not meet the predetermined conditions, for example, red when it exceeds a predetermined range. When it is below the range, the defective construction part is displayed in blue, and the difference is indicated by the color density distribution or numerical value. Further, for example, a construction defective portion may be indicated by an instruction line and expressed numerically.
The sent inspection result can be confirmed on the display unit (inspection display means) of the site terminal 100. The inspection result is sent in a form that is easy to see on the site terminal 100. For example, as shown in the evaluation column of FIG. 5, if the inspection is passed, it is marked with "○", and if there is a construction defective part, it is marked with "x", and a covering material image showing the construction defective part is sent.

Since the server 300 is provided with such an inspection means 302, it is possible to obtain a highly objective inspection result. Further, since the inspection result can be confirmed on the screen of the site terminal 100, it is possible to confirm the construction defective portion at the site and perform the finishing process, which facilitates the construction work of the covering material. In particular, by displaying the inspection result on the above-mentioned covering image, it is easy to specify the finishing process at the site, and the workability is improved.
In this embodiment, the inspection result is automatically transmitted to the site terminal 100, but it does not have to be automatically transmitted. The site terminal 100 may be connected to the server 300 and browsed from the inspection history database 406 of the storage device 400.

The proof means 303 performs a process of creating and editing a covering material image (covering material thickness data) and / or an inspection result in a predetermined format, and issues a certificate. Further, the certificate is converted into non-editable data and stored in the certificate database 407 described later.
For example, it issues a certificate, construction evaluation report, or inspection report certifying that the quality is certified by a predetermined organization. Further, data including the thickness data of the covering material may be transmitted to the homepage or server of a predetermined institution, and a certificate certified by the predetermined institution may be issued.
Since the thickness data of the covering material is highly objective data, it is possible to easily and quickly obtain the accreditation of a predetermined institution that requires complicated procedures without degrading the reliability.

The data providing means 304 provides the viewing of necessary information in a predetermined manner as shown in FIG. 5, which will be described later, in response to the request of the management terminal 200 connected to the server 300 through the network 20.

The authentication means 305 requests a connection qualification when the management terminal 200 connects to the server. For example, password, face recognition, wrist blood vessel recognition and the like. Further, the IP address of the management terminal 200 may be registered in advance so that only the computer having the registered IP address can be connected.
In addition to the connection qualification of the administrator of the management terminal 200, the connection qualification may be determined only for viewing or according to the input contents.

[Storage device 400]
The storage device 400 is provided with a covering material thickness database 401. As other databases, a coating material spraying database 402, a target surface temperature database 403, a coating material product information database 404, a construction history database 405, an inspection history database 406, and a certificate database 407 are provided.
The storage device 400 may be provided inside the server 300 or may be connected to the outside.

The thickness database 401 of the covering material stores the thickness data (covering material image) of the covering material according to the target surface. In this embodiment, the image of the covering material is stored. In addition to the thickness data of the covering material, a photograph of the covering material after construction may be registered according to the target surface.

The spraying database 402 of the covering material stores the spraying conditions according to the target surface. In particular, in the case of a two-component rigid urethane foam, it is preferable that the two-component mixing temperature, the two-component mixing pressure and the spray flow rate are stored. Rigid urethane foam is preferable in terms of quality control because its quality varies greatly depending on the spray conditions. Such spraying data of the covering material can be stored by transmitting the data input by the site terminal 100 or by connecting the site terminal 100 and the foaming machine and automatically transmitting the data.

The temperature database 403 of the target surface stores the temperature distribution of the target surface. Such temperature data of the target surface can be measured by using a thermo camera or the like, and can be stored by transmitting the data from the field terminal 100.

The product information database 404 of the covering material stores information indicating the performance of the material of the covering material used for the target surface. For example, the manufacturer name, product name, model number, component, etc. of each material can be mentioned. These data can also be stored by transmitting the data input by the field terminal 100. A code reader may be connected to the field terminal 100 to read a QR code (registered trademark), a bar code, or the like displayed on the container of the raw material.

The construction history database 405 stores information such as the construction company, the contractor, the construction date, and the number of constructions according to the target surface. These data can also be stored by transmitting the data input by the field terminal 100.

The inspection history database 406 stores the inspection results of the inspection means according to the target surface. When the inspection fails, it is preferable to register the inspection result after the finishing process based on the inspection history without overwriting, for example, as shown in FIG. By registering the inspection results based on the inspection history in this way, it becomes clear how the finishing process was performed, and the reliability of the data is also improved.
The certificate database 407 stores certificates and the like created by the certification means according to the target surface.

Next, the flow of this system will be described.
As shown in FIG. 4a, first, basic data such as the position information of the target surface 35, the construction date, the builder, and the temperature of the target surface are input to the site terminal 100. Then, after the covering material is applied, the measurement of the construction shape (three-dimensional data of the covering material) is started by the three-dimensional measuring device 150 set at a predetermined place. As a result, the site terminal 100 acquires the construction shape (three-dimensional data of the covering material), calculates the covering material image (thickness data of the covering material), and stores the covering material image together with the basic data in the storage device of the server 300. Automatically transmit to 400.
In the server 300, the transmitted covering material image (covering material thickness data) is inspected by the inspection means 302, and the basic data, the covering material image and the inspection result are stored in each database of the storage device 400. At the same time, the inspection result is transmitted to the site terminal 100. The builder can confirm the inspection result on the display unit (inspection display means) of the site terminal 100. If there is a construction defect in the inspection result, the surplus is cut for the part that is too thick and additional finishing treatment is performed for the part that is too thin. After that, the three-dimensional measuring device 150 measures the construction shape for the second time, calculates the second covering material image, and transmits the image to the storage device 400 again. When the inspection result is passed, the construction of the covering material on the target surface is completed.

On the other hand, as shown in FIG. 4b, the management terminal 200 connects to the server 300 via the authentication means 305 through the network 20, selects browsing data from each database of the storage device 400, and outputs the output screen of the management terminal 200 and the like. Browse each data with. For example, FIG. 5 is an example of a browsing screen in which data on each wall of room 101 of the X building is selected. The data includes the target surface, covering image, evaluation, construction date, number of constructions, product information, temperature of the target surface, spraying information, and information on workers and contractors. The evaluation displays the result of the inspection means, and is a covering material image to which a thickness distribution map is attached. When the evaluation is "x", the defective construction part can be seen in the covering material image. In FIG. 5, it can be seen that the construction of the heat insulating material on the west wall of Building X 101 failed the first time and passed the second time. In addition, since the image of the covering material for each construction is stored, the content of the finishing process can be confirmed from the difference between the first and second construction conditions. Since the second construction is a finishing work, the temperature of the target surface is not measured. Further, when the evaluation is “x”, whether the covering material exceeds the predetermined range, falls below the predetermined range, or both may be included in the evaluation of FIG.
In this way, the inspector can obtain highly objective data on the quality of the heat insulating material on the wall surface of Room 101 of the X building without actually going to the site.

In this way, since the covering material management system 10 acquires the three-dimensional shape of the covering material and calculates the thickness data of the covering material, it is possible to accurately evaluate the thickness of the covering material that cannot be visually determined after construction. .. In particular, since there is no human operation until the thickness data of the covering material is calculated, there is no human error, and the thickness data of the covering material with high objectivity can be obtained, which is suitable for quality assurance. In addition, by using the data, highly reliable inspection can be performed and a highly reliable certificate can be created.
On the other hand, since the obtained thickness data of the covering material is stored in the server 300, the objectivity is maintained. In particular, since the coating material thickness data registered in the covering material thickness database 401 of the storage device 400 is locked so that it cannot be moved or edited, the objectivity of the calculated covering material thickness data is Can be retained. Therefore, highly reliable data can be confirmed at any time.
Since the covering material management system 10 includes inspection means, it is possible to prevent duplication of inspections by each person in charge. In addition, since it is equipped with a proof means, it is possible to simplify the complicated procedure for creating a certificate without deteriorating the reliability.
In this covering material management system 10, since the inspection result of the covering material thickness data is fed back to the site terminal 100, the man-hours for returning and returning can be reduced, and the construction work of the covering material becomes easy. Therefore, excess and spraying can be prevented, and the raw materials used during construction can be reduced. Moreover, regardless of the skill level of the worker, the construction can be performed with high accuracy and the uniform construction quality can be measured.

In the covering material thickness management system 10 of FIG. 1, the construction shape including the three-dimensional coordinates of the surface of the covering material and the reference three-dimensional coordinates of three or more points whose distances from the target surface are known and the same is three-dimensional. Although the thickness data of the covering material was calculated as the data, the three-dimensional data of the covering material is not particularly limited. For example, the applicant proposes a method for measuring the three-dimensional shape of a covering material in Japanese Patent Application No. 2018-208451. In this method, the position coordinates of the target surface before construction of the covering material and the position coordinates of the surface of the covering material after construction are measured, and the three-dimensional shape of the covering material or the thickness of the covering material is obtained from the difference. .. As a method that does not use a three-dimensional scanner or stereo camera, after spraying on the target surface, the spray thickness is measured using a laser range finder, and the three-dimensional data of the covering material is obtained by associating each position coordinate with the thickness. You may create it. However, since the measurement work takes time and the position accuracy is not high, a three-dimensional scanner or a stereo camera capable of scanning a wide range with high accuracy is preferable.

In the covering material thickness management system 10 of FIG. 1, the covering material thickness data creating means 111 is provided in the field terminal 100, but it may be provided in the server 300. In that case, the three-dimensional measuring device 150 may be directly connected to the network 20 by using a data communication card or the like instead of using the field terminal as a computer.
Further, in the covering material thickness management system 10 of FIG. 1, the inspection means 302 is provided in the server 300, but it may be provided in the field terminal 100. However, in order to maintain the objectivity of the inspection result, it is preferable to provide the server 300.
Further, in the covering material thickness management system 10 of FIG. 1, an electronic signature or a time stamp may be acquired for each data. By inputting electronic time information into the data in this way, it is possible to compare with the basic data and further maintain the objectivity.

Next, in the covering material thickness management system 10 of FIG. 1, the position information of the target surface is input by the field terminal 100, but the covering material thickness management system 10a of FIG. 6 is a three-dimensional measuring device.

Specifically, the three-dimensional measuring device 150 is provided with a GPS (Global Positioning System) receiver 151 and an electronic compass 152 for detecting the orientation of the three-dimensional measuring device 150. Then, when data is transmitted from the three-dimensional measuring device 150 to the server 300, GPS position information (latitude, mildness, altitude) and its orientation information are transmitted to the server 300.
On the other hand, the target surface specifying means of the server 300 includes a building coordinate table 408 stored in the storage device 400 and a target surface calculating means 307. In the building coordinate table 408, the position coordinates of the latitude, longitude, and altitude of the building and each room are recorded by design drawings and the like.
The target surface calculation means 307 receives the GPS position information and the orientation information, refers to the building coordinate table 408, identifies the position of the three-dimensional measuring device 150 from the GPS position information in which room of the building, and the building. With reference to the coordinate table 408, it is calculated from the orientation information which wall (object surface) of the room the three-dimensional measuring device 150 faces. Then, the wall (target surface) is registered in the thickness database 401 of the covering material.
Since it is configured in this way, the operation of inputting the position of the target surface can be omitted, and the burden on the operator can be further reduced. If GPS cannot be used indoors, etc., the information of the motion sensor (acceleration sensor, gyro sensor, etc.) provided in the three-dimensional measuring device is added to the indoor positioning system using radio waves such as WiFi and Bluetooth (registered trademark). In combination, position information and orientation information may be acquired.
