[0018] Hereinafter, a measurement system, a measurement method, and a construction method according to the present embodiment will be described with reference to the drawings.

[0019] (First embodiment) 1 is a diagram showing an example of a schematic configuration of a measurement system 1 according to the first embodiment. Before driving a pile 200, the measurement system 1 measures information related to the specifications of the pile 200 to be driven.

[0020] The driving of the piles 200 means burying one or more piles 200 (for example, steel pipe piles) in a predetermined driving position at a construction site, and is also referred to as construction in this embodiment. Note that one pile 200 may be driven into one driving position, and two or more piles 200 may be driven into one driving position. For example, when two piles 200 are driven into one driving position, the pile 200 driven first into the driving position may be called the "lower pile", and the pile driven (built) next on the lower pile may be called the "upper pile". For example, when three piles are driven into one driving position, the pile 200 driven first into the driving position may be called the "lower pile", the pile 200 driven (built) on the lower pile may be called the "middle pile", and the pile 200 driven (built) last on the middle pile may be called the "upper pile". In the following description, information regarding where the pile is buried (top pile, middle pile, bottom pile, etc.) may be referred to as "category."

[0021] The pile 200 has at least a main body 210. The main body 210 has, for example, a straight pipe body. The pile 200 may have a blade 220. The blade 220 has a spiral blade on the outer periphery of the main body 210. The blade 220 may be attached to the tip of the main body 210, or may be attached to a part other than the tip. For example, the blade 220 may be attached to a position shifted vertically upward from the tip of the main body 210 by a predetermined length. In this way, the pile 200 may have the blade 220 attached thereto, or may not have the blade 220.

[0022] An example of a schematic configuration of a measurement system 1 according to this embodiment will be described with reference to FIG.

[0023] The measurement system 1 includes an imaging unit 10 and an information processing device 20.

[0024] The imaging unit 10 captures an image of the pile 200 to be driven into a certain driving position. The imaging unit 10 transmits the captured image to the information processing device 20. The captured image may be a still image or a moving image. For example, the imaging unit 10 is installed in the pile driver 100 and captures the pile 200 held by the pile driver 100. For example, the imaging unit 10 is connected to the information processing device 20 via a communication network N. The imaging unit 10 may transmit the image to the information processing device 20 via the communication network N. The position at which the imaging unit 10 is installed is not particularly limited, and the imaging unit 10 may be fixed to a position other than the pile driver 100. The captured image may include the short side direction (radial direction) of the pile 200 held by the gripping unit 120, and the entire long side direction of the pile 200 may not be captured in the captured image. For example, the imaging unit 10 may be fixed to a moving body such as a drone. For example, the imaging unit 10 is a camera.

[0025] The communication network N may be a transmission path for wired communication, a transmission path for wireless communication (e.g., wireless LAN), or a combination of a transmission path for wireless communication and a transmission path for wired communication. The communication network N may be a mobile communication network such as a mobile phone network, a wireless packet communication network, the Internet, a dedicated line, or a combination of these. For example, the communication network N may use a low-power wide-area network (LPWAN), or may use a short-range wireless communication standard such as ZigBee (registered trademark), WiFi (registered trademark), or BLE.

[0026] The pile driver 100 shown in Fig. 1 is well known and therefore will not be described in detail. The pile driver 100 is a machine that rotates a pile 200 while erecting it, and buries it in the ground. For example, the pile driver 100 includes a leader 110 and a gripping unit 120. The leader 110 is erected in the vertical direction. The gripping unit 120 grips the pile 200 to be driven.

[0027] The gripping unit 120 is installed so as to be movable along the leader 110. The gripping unit 120 moves up and down along the longitudinal direction of the leader 110. The gripping unit 120 moves down along the leader 110 while rotating and gripping the pile 200. As a result, the pile 200 is pressed into the ground G while rotating.

[0028] The information processing device 20 acquires the captured image from the imaging unit 10 via the communication network N. The information processing device 20 may be installed in the pile driver 100. For example, the information processing device 20 may be installed in the driver's cab of the pile driver 100. The information processing device 20 may be fixed to a position other than the pile driver 100, or may be a device that can be carried (including worn) by a user such as an operator or a construction manager. For example, the information processing device 20 is a computer or a smart device. For example, the information processing device 20 is a wearable terminal or a portable information terminal. An example of a wearable terminal is smart glasses or a smart watch that has an imaging function and a function of displaying digital information on a display screen. An example of a portable information terminal is a smartphone or a tablet terminal. However, the information processing device 20 is not limited to a smart device that can be carried (including worn) by a user, and may be installed at the work site, for example.

[0029] An example of the configuration of the information processing device 20 according to the first embodiment will be described below.

[0030] The information processing device 20 includes a measuring unit 21, a storage unit 22, and an output unit 23. These components are realized by, for example, a hardware processor such as a CPU (Central Processing Unit) executing a program (software). In addition, some or all of these components may be realized by hardware (including circuitry) such as an LSI (Large Scale Integrated circuit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a GPU (Graphics Processing Unit), or may be realized by cooperation between software and hardware. The program may be stored in advance in a storage device such as an HDD (Hard Disk Drive) or a flash memory (a storage device having a non-transient storage medium), or may be stored in a removable storage medium such as a DVD or a CD-ROM (a non-transient storage medium), and installed in the storage device by mounting the storage medium in a drive device. The storage device may be composed of, for example, a HDD, a flash memory, an EEPROM (Electrically Erasable Programmable Read Only Memory), a ROM (Read Only Memory), or a RAM (Random Access Memory).

[0031] The measuring unit 21 measures diameter information, which is at least one or both of the outer diameter of the main body 210 of the pile 200 (hereinafter referred to as the “main body diameter”) and the blade diameter of the pile 200, based on the captured image captured by the imaging unit. The blade diameter is the outer diameter of the blade portion 220.

[0032] Fig. 2 is a diagram showing a first example of a captured image according to the first embodiment. The example shown in Fig. 2 shows a captured image in which the blade portion 220 is captured near the center of the monitor of the imaging unit 10. For example, information on the actual dimensions (two-dimensional) of the pile 200 per pixel (hereinafter referred to as "dimension information") is stored in advance in the storage unit 22. For example, the measurement unit 21 measures at least one of the main body diameter and the blade diameter based on the dimension information stored in the storage unit 22.

[0033] For example, the measuring unit 21 calculates the number of pixels of the blade diameter from the captured image, and obtains the blade diameter based on the calculated number of pixels and the dimension information. As an example, it is assumed that the actual dimension of 10 [cm] corresponds to 30 pixels on the captured image. And it is assumed that the measuring unit 21 calculates that the number of pixels of the blade diameter is 300 pixels. In this case, the measuring unit 21 obtains 300 pixels × (10 [cm] / 30 pixels) to obtain the actual dimension of the blade diameter = 100 [cm]. The measuring unit 21 can measure the actual dimension of the main body diameter by calculating how many pixels the main body diameter is on the captured image in a similar manner. However, the method of measuring the main body diameter and the blade diameter by the measuring unit 21 is not limited to this, and various methods can be applied as long as the actual dimensions of the main body diameter and the blade diameter can be obtained by applying image processing to the captured image.

[0034] FIG. 3 is a diagram showing a second example of a captured image according to the first embodiment. FIG. 3 shows a state in which the pile 200 is lowered vertically downward by the gripping unit 120 from the state shown in FIG. 2. In FIG. 3, the entire length of the pile 200 (hereinafter referred to as "pile length") is captured in the captured image. Therefore, the measuring unit 21 may measure the pile length of the pile 200 in addition to the diameter information. For example, the measuring unit 21 may measure the pile length in actual dimensions by determining how many pixels the pile length is on the captured image. In addition, a worker or the like may apply a marking G to a predetermined position of the pile 200 in advance, and the measuring unit 21 determines how many pixels the position from the tip of the pile 200 to the marking G and the position from the marking G to the bottom end of the gripping unit 120 are on the captured image.

[0035] Here, the actual dimension from the tip of the pile 200 to the marking G is known and stored in advance in the storage unit 22. Also, information on how many centimeters the top end of the pile 200 is above the bottom end of the gripping unit 120 (hereinafter, "top end information") is specified in advance and stored in the storage unit 22. This allows the measuring unit 21 to measure the actual pile length based on the dimensional information. Note that, regardless of the marking G, the measuring unit 21 may measure the actual pile length using the number of pixels from the tip of the pile 200 to the bottom end of the gripping unit 120 on the captured image, the dimensional information, and the top end information.

[0036] FIG. 4 is a diagram showing a third example of a captured image according to the first embodiment. FIG. 4 shows a case where the entire length of the pile 200 cannot be captured on the captured image. In the example shown in FIG. 4, the markings H are applied, for example, at predetermined intervals (for example, 2 [m]) based on the tip of the pile 200. The markings H are applied to the pile 200 in advance by an operator or the like. Information on the predetermined intervals is known and stored in the storage unit 22. The measurement unit 21 counts the number of all markings H from each captured image of the pile 200 moving vertically downward or vertically upward. Then, the measurement unit 21 may measure the actual pile length by using the count number, the number of pixels from the uppermost marking H to the bottom end of the gripping unit 120, the top end information, and the dimension information.

[0037] The storage unit 22 may store the results of measurements made by the measurement unit 21. For example, the storage unit 22 may store information such as diameter information and pile length measured by the measurement unit 21 for each driving position.

[0038] The output unit 23 outputs the results measured by the measurement unit 21. For example, the output unit 23 may include a display device. For example, the output unit 23 may output the measured diameter information and pile length to the display unit. The output unit 23 may output the results measured by the measurement unit 21 in a manner that appeals to at least one of a person's vision, hearing, and touch. The output unit 23 may output the results measured by the measurement unit 21 to an external device such as a communication terminal of a worker at the site or a construction manager.

[0039] The following is a diagram for explaining the flow of the measurement method according to the first embodiment. Fig. 5 is a diagram for explaining the flow of the measurement method according to the first embodiment.

[0040] When driving the pile 200 into a certain driving position, the pile 200 is gripped by the gripping unit 120 of the pile driver 100. At this time, the information processing device 20 acquires a captured image from the imaging unit 10 (step S101). Note that in step S101, the information processing device 20 may acquire a captured image of the pile 200 when the pile driver 100 is moving the pile 200 vertically downward while rotating it.

[0041] The information processing device 20 measures at least diameter information based on the captured image acquired in step S101 (step S102). The information processing device 20 outputs the diameter information measured in step S102 (step S103). If the diameter information output in step S103 matches the diameter information of the pile 200 to be driven into the driving position specified in the construction plan, the user executes driving of the pile 200 held by the gripping unit 120. Note that, if pile length information is output in addition to the diameter information in step S103, the user executes driving of the pile 200 held by the gripping unit 120 if the diameter information and pile length output in step S103 match the diameter information and pile length of the pile 200 to be driven into the driving position specified in the construction plan.

[0042] As described above, the measurement system 1 of the first embodiment includes the imaging unit 10 and the measuring unit 21. The imaging unit 10 captures an image of the pile 200. The measuring unit 21 measures diameter information, which is at least one of the outer diameter of the main body 210 of the pile 200 and the blade diameter of the pile 200, or both, based on the captured image captured by the imaging unit 10.

[0043] With this configuration, the user can measure pile information without the worker using a measuring instrument such as a tape measure as a final confirmation task when driving the pile 200. As a result, the measurement system 1 can shorten the time required for the confirmation task of the pile to be driven when driving the pile, and can prevent human error.

[0044] Second Embodiment 6 is a diagram showing an example of a schematic configuration of a measurement system 1A according to the second embodiment. In the following description, parts having the same functions as those described in the first embodiment are given the same names and symbols, and specific descriptions of the functions are omitted.

[0045] The measurement system 1A differs from the first embodiment in that it includes a comparison unit 32 that determines whether or not diameter information measured by the measurement unit 21 matches specification information registered in advance in the measurement system 1A.

[0046] The measurement system 1A includes an imaging unit 10 and an information processing device 20A.

[0047] The information processing device 20A acquires a captured image from the imaging unit 10 via the communication network N, similar to the first embodiment. The installation position of the information processing device 20A is similar to the first embodiment. The information processing device 20A is, for example, a computer or a smart device, similar to the first embodiment.

[0048] The information processing device 20A includes a measuring unit 21, a storage unit 22A, a pile number acquisition unit 30, a reception unit 31, a collation unit 32, and an output unit 23A. These components are realized, for example, by a hardware processor such as an APU executing a program (software). In addition, some or all of these components may be realized by hardware (including circuitry) such as an LSI, ASIA, FPGA, or GPU, or may be realized by cooperation between software and hardware. The program may be stored in a storage device such as an HDD or flash memory (a storage device having a non-transient storage medium) in advance, or may be stored in a removable storage medium such as a DVD or AD-ROM (a non-transient storage medium), and may be installed in the storage device by mounting the storage medium in a drive device. The storage device is, for example, configured of an HDD, flash memory, EEPROM, ROM, or RAM.

[0049] The storage unit 22A stores specification information including diameter information of piles used at the site. For example, the storage unit 22A stores a plurality of pile numbers and specification information including diameter information of piles corresponding to each pile number (hereinafter referred to as "specification information") in association with each other. The pile number is information for identifying a driving position. This pile number is set by a user or the information processing device 20A using a pile setting plan as shown in FIG. 7, for example. The pile setting plan information is stored in the storage unit 22A. The specification information is information on each item such as the classification, the pile diameter, thickness, material of each of the main body 210 and the wing 220, the type of joint, the position of the joint (upper end or lower end), and the pile length. The specification information is set by the user or the information processing device 20A from a construction plan or the like. Therefore, the storage unit 22A has specification information of one or more piles 200 to be driven registered in advance for each driving position. Hereinafter, the specification information of the piles 200 stored in the storage unit 22A may be referred to as "registered specifications".

[0050] FIG. 8 is a diagram showing a first example of registered specifications stored in the storage unit 22A in table format. In the example shown in FIG. 8, multiple pile numbers are associated with specification information including diameter information of one or more piles to be driven into each pile number. For example, when two piles, an upper pile and a lower pile, are driven into pile number "1", specification information of the upper pile and specification information of the lower pile are associated with pile number "1". A combination of piles (e.g., an upper pile and a lower pile) to be driven into one driving position is called a pile set. The specifications of the pile set with pile number "1" include specification information of the upper pile and specification information of the lower pile.

[0051] Fig. 9 is a diagram showing a second example of registered specifications stored in the storage unit 22A in a table format. In the example shown in Fig. 9, the storage unit 22A includes a pile specification table and a pile number table.

[0052] FIG. 9(a) is an example of a pile specification table. In the pile specification table, pile codes are associated with specification information of pile sets. The pile code is information that represents the specification pattern of the entire pile set after all piles have been driven into one driving position. In other words, the pile code is information that represents the specification of the combination of piles 200 to be driven into one driving position. Therefore, when the same pile code is assigned to multiple driving positions, the specifications and combinations (including the driving order) of the piles to be driven into each of the multiple driving positions are, in principle, all the same.

[0053] FIG. 9(b) is an example showing a pile number table. In the pile number table, pile numbers and pile codes are associated with each other. In this embodiment, the pile specification table and the pile number table are stored in the storage unit 22A, so that the specification information of the pile to be driven into the driving position is associated with each driving position in advance. The pile specification table and the pile number table may be combined into one table.

[0054] The pile number acquisition unit 30 acquires the pile number of a position where the pile driver 100 drives the pile 200 (hereinafter, referred to as a "driving target position") among the multiple driving positions. For example, the pile number acquisition unit 30 may acquire the pile number by a method described with reference to FIG. 10. For example, as shown in FIG. 10, a pile number is marked in advance at each driving position by a prime contractor or the like at the site. For example, a reinforcing bar 300 is embedded in each driving position, and a label 310 showing a pile number indicating each driving position is attached to the upper end portion of the embedded reinforcing bar 300. Usually, the reinforcing bar 300 is embedded in the ground so that the upper end of the reinforcing bar 300 does not protrude from the ground, and the label 310 is visible to the user. The label 310 may be displayed in a color indicating the pile number. In this way, the label 310 indicating the pile number is attached to each driving position. The label 310 indicates the pile number by displaying the marking of the pile number or a color indicating the pile number. However, the label 310 is not limited to the marking of the stake number or the color indicating the stake number, and it is sufficient that the label 310 indicates the stake number, and there is no particular limitation on the manner in which the stake number is indicated.

[0055] During construction, the user causes the information processing device 20A to read the pile number displayed on the label 310 at the target position for concrete pouring. In this case, the pile number acquisition unit 30 may include an imaging unit such as a camera. For example, the pile number acquisition unit 30 captures an image of the pile number attached to the label and acquires the label from the captured image (hereinafter referred to as the "label image"). For example, the pile number acquisition unit 30 reads the pile number by applying known image processing to the label image. Note that the imaging unit that captures the label image may be the imaging unit 10. In other words, the imaging unit that captures the label and the imaging unit that captures the pile 200 may be shared by the imaging unit 10. The pile number acquisition unit 30 inputs the acquired pile number to the reception unit 31.

[0056] The reception unit 31 receives input of the pile number from the pile number acquisition unit 30. However, the reception unit 31 may also receive the pile number of the concrete driving target position from a source other than the pile number acquisition unit 30. For example, the reception unit 31 may receive the pile number of the concrete driving target position from an information terminal such as a mobile terminal or computer owned by the user. The reception unit 31 may also receive the pile number of the concrete driving target position from an operation unit such as a touch panel or keyboard provided on the information processing device 20A.

[0057] The collation unit 32 collates the measurement value of the diameter information measured by the measurement unit 21 with the registered specifications of the diameter information of the pile stored in the storage unit 22A. For example, the collation unit 32 collates the measurement value of the diameter information of the pile 200 measured by the measurement unit with the registered specifications of the diameter information in the storage unit 22A associated with the pile number accepted by the acceptance unit 31. The collation unit 32 outputs the result of the collation between the measurement value of the diameter information measured by the measurement unit 21 and the registered specifications of the diameter information in the storage unit 22A to the output unit 23A.

[0058] As a more specific example, the collation unit 32 reads out the specification information associated with the pile number received by the reception unit 31 from the table shown in Fig. 8 or 9. Then, the collation unit 32 compares the registered specifications (body diameter and / or blade diameter) of the read diameter information with the diameter information (body diameter and / or blade diameter) measured by the measurement unit 21, and if they match, it outputs information indicating that the collation was successful to the output unit 23A, and if they do not match, it outputs information indicating that the collation was unsuccessful to the output unit 23A.

[0059] The output unit 23A outputs the result of the comparison by the comparison unit 32 to an external device or the like. For example, the output unit 23A may output an error when the measurement value of the diameter information measured by the measurement unit 21 does not match the registered specifications of the diameter information in the storage unit 22A. For example, the output unit 23A outputs the error in a manner that appeals to at least one of the human sense of sight, hearing, and touch. As a manner that appeals to the human sense of sight, the error may be displayed on a display screen, or an indicator light indicating an error may be turned on. As a manner that appeals to the human sense of hearing, a sound indicating an error may be output. As a manner that appeals to the human sense of touch, the information processing device 20A may be vibrated.

[0060] When the measurement value of the diameter information measured by the measuring unit 21 matches the registered specifications of the diameter information in the storage unit 22A, the output unit 23A may output information indicating that the match was successful in a manner that appeals to at least one of the human senses of sight, hearing, and touch. In that case, it goes without saying that a sound different from a sound indicating an error, a display different from a display indicating an error, or a vibration different from a vibration indicating an error may be output so that it is clear that there is no error.

[0061] Note that, like output unit 23, output unit 23A may output diameter information measured by measurement unit 21.

[0062] The following is a diagram for explaining the flow of the measurement method according to the second embodiment. Fig. 11 is a diagram for explaining the flow of the measurement method according to the second embodiment.

[0063] The information processing device 20A receives, at the receiving unit 31, a pile number indicating a driving position where the pile 200 will be driven by the pile driver 100 (step S201).

[0064] The information processing device 20A acquires a captured image from the imaging unit 10 (step S202). Note that, in step S202, the information processing device 20A may acquire a captured image of the pile 200 when the pile driver 100 moves the pile 200 vertically downward while rotating it. Note that step S201 may be executed after step S202, or may be executed simultaneously with step S202.

[0065] The information processing device 20A measures at least the diameter information based on the captured image acquired in step S202 (step S203). The information processing device 20A compares the diameter information measured in step S203 with the registered specifications of the diameter information associated with the pile number received by the reception unit 31 (step S204). When the diameter information measured in step S203 matches the registered specifications of the diameter information associated with the pile number received by the reception unit 31, the information processing device 20A outputs information indicating that the comparison is successful by displaying it on the display screen (step S205). When the diameter information measured in step S203 does not match the registered specifications of the diameter information associated with the pile number received by the reception unit 31, the information processing device 20A outputs information indicating that the comparison is unsuccessful by displaying it on the display screen (step S206). Therefore, when the comparison is successful, the user causes the pile driver 100 to drive the pile 200 held by the gripper 120. If the collation fails, the user checks the specifications of the stake 200 held by the gripper 120 and replaces it with a stake 200 of appropriate specifications.

[0066] In this way, the construction method of driving the pile 200 into a predetermined driving position using the measurement system 1A or the measurement method of the second embodiment includes holding the pile 200 to be driven by the pile driver 100, taking an image of the pile 200 by the imaging unit 10, measuring diameter information, which is at least either the outer diameter of the body 210 of the pile 200 or the wing diameter of the pile 200 or both, based on the image taken by the imaging unit 10, comparing the specification information of the pile 200 previously associated with the pile number indicating the predetermined position with the measured value of the diameter information of the pile 200, and starting the driving of the pile held by the pile driver 100 if the comparison is successful. With this configuration, the time required for construction can be shortened.

[0067] As described above, the measurement system 1A of the second embodiment not only achieves the same effects as the first embodiment, but also compares the measured value of the diameter information with the registered specifications of the diameter information, thereby further shortening the time required for checking the piles to be driven.

[0068] In addition, if the measuring unit 21 further measures the actual pile length, in step S204, the comparison unit 32 compares the measurement values ​​of the diameter information and pile length measured by the measuring unit 21 with the registered specifications of the diameter information and pile length associated with the pile number received by the receiving unit 31, and if the comparison is successful, proceeds to step S205, or if the comparison is unsuccessful, proceeds to step S206.

[0069] (Third embodiment) 12 is a diagram showing an example of a schematic configuration of a measurement system 1B according to the third embodiment. In the following description, parts having the same functions as those described in the first and second embodiments are given the same names and symbols, and specific descriptions of the functions are omitted.

[0070] The measurement system 1B differs from the second embodiment in that it includes a reading unit 40 that reads pile information 400, which is information relating to the specifications of the pile 200.

[0071] The measurement system 1B includes an imaging unit 10 and an information processing device 20B.

[0072] The information processing device 20B acquires a captured image from the imaging unit 10 via the communication network N, similar to the first embodiment. The installation position of the information processing device 20B is similar to the first embodiment. The information processing device 20B is, for example, a computer or a smart device, similar to the first embodiment.

[0073] The information processing device 20B includes a measuring unit 21, a reading unit 40, a storage unit 22B, a pile number acquisition unit 30, a reception unit 31, a collation unit 32B, and an output unit 23B. These components are realized, for example, by a hardware processor such as a CPU executing a program (software). In addition, some or all of these components may be realized by hardware (including circuitry) such as an LSI, BSIC, FPGB, or GPU, or may be realized by cooperation between software and hardware. The program may be stored in a storage device such as an HDD or flash memory (a storage device having a non-transient storage medium) in advance, or may be stored in a removable storage medium such as a DVD or CD-ROM (a non-transient storage medium), and may be installed in the storage device by mounting the storage medium in a drive device. The storage device is, for example, configured of an HDD, a flash memory, an EEPROM, a ROM, or an RBM.

[0074] When the pile information 400, which is information on the specifications, is displayed on the pile 200, the reading unit 40 reads the pile information 400 from the captured image. The reading unit 40 outputs pile reading information, which is information on the specifications of the pile corresponding to the read pile information 400, to the collation unit 32B. Here, the pile information 400 may include information representing pile reading information such as the material, steel pipe thickness, pile length, and lot number of the pile 200. The pile reading information may include information of the specifications of the pile 200 that cannot be measured or is difficult to measure by the measurement unit 21. It is difficult to measure the material, steel pipe thickness, and lot number of the pile from the captured image. Therefore, the pile reading information may include information that is difficult to measure from the captured image. The pile information 400 may be displayed on the pile 200. For example, the pile information 400 may be directly printed on the main body unit 210, or a label on which the pile information 400 is printed may be attached to the main body unit 210. The stake information 400 may be a one-dimensional code such as a barcode, or a two-dimensional code such as a QR code (registered trademark). The stake information 400 may be a string of numbers, a string of symbols, a string of alphabets, or a combination thereof according to a predefined rule. Information on the predefined rule may be stored in the storage unit 22B.

[0075] The reading unit 40 reads the pile information 400 displayed on the pile 200, and outputs pile reading information (eg, the material of the pile 200, the steel pipe thickness, the pile length, the lot number, etc.) from the read pile information 400 to the collation unit 32B.

[0076] Storage unit 22B stores information similar to the information stored in storage unit 22A.

[0077] The collation unit 32B collates information including the measured value of the diameter information measured by the measurement unit 21 and the pile reading information of the pile output from the reading unit 40 with the registered specifications associated with the pile number received by the reception unit 31. For example, the collation unit 32B collates the measured value of the diameter information of the pile 200 measured by the measurement unit with the registered specifications of the diameter information in the storage unit 22B associated with the pile number received by the reception unit 31, and collates the pile reading information of the pile 200 output from the reading unit 40 (e.g., the material of the pile 200, the steel pipe thickness, the pile length, the lot number, etc.) with the registered specifications in the storage unit 22B associated with the pile number received by the reception unit 31 (e.g., the material of the pile 200, the steel pipe thickness, the pile length, the lot number, etc.). The collation unit 32B outputs the collation result to the output unit 23B.

[0078] The output unit 23B outputs the collation result of the collation unit 32B to an external device, etc. The output mode of the output unit 23B is similar to that of the output unit 23A, and therefore a description thereof will be omitted.

[0079] The following is a diagram for explaining the flow of the measurement method according to the third embodiment. Fig. 13 is a diagram for explaining the flow of the measurement method according to the third embodiment.

[0080] The information processing device 20B receives, at the receiving unit 31, a pile number indicating a driving position where the pile 200 will be driven by the pile driver 100 (step S302).

[0081] The information processing device 20B acquires a captured image from the imaging unit 10 (step S302). Note that, in step S302, the information processing device 20B may acquire a captured image of the pile 200 when the pile driver 100 moves the pile 200 vertically downward while rotating it. Note that step S301 may be executed after step S302, or may be executed simultaneously with step S302.

[0082] The information processing device 20B measures at least the diameter information based on the captured image acquired in step S302 (step S303). The information processing device 20B reads the pile information 400 printed on the pipe surface of the pile 200 while the pile 200 is being held by the gripping unit 120 or while the pile 200 is rotating or being embedded in the ground by rotation, and acquires pile reading information such as the steel pipe thickness, steel pipe material, and pile length from the read pile information 400 (step S304). This makes it possible to reduce reading errors in the pile information 400.

[0083] The information processing device 20B compares the diameter information measured in step S303 and the pile reading information acquired in step S304 with the registered specifications associated with the pile number received by the reception unit 31 (step S305). If the comparison is successful, the information processing device 20B outputs information indicating the success of the comparison by displaying it on the display screen (step S306). If the comparison is unsuccessful, the information processing device 20B outputs information indicating the failure of the comparison by displaying it on the display screen (step S307). Therefore, if the comparison is successful, the user drives the pile 200 held by the gripping unit 120. If the comparison is unsuccessful, the user checks the specifications of the pile 200 held by the gripping unit 120 and replaces it with a pile 200 of appropriate specifications.

[0084] As described above, the measurement system 1B of the third embodiment not only achieves the same effects as the first and second embodiments, but also includes a reading unit 40 that reads pile information 400, making it possible to obtain information on the specifications of the pile 200, which is difficult to obtain from a captured image, without using a measuring instrument.

[0085] In addition, the output unit 23B may output diameter information measured by the measurement unit 21 and pile reading information acquired by the reading unit 40 in the same manner as the output unit 23, in addition to the result of the comparison by the comparison unit 32B.

[0086] (Fourth embodiment) 14 is a diagram showing an example of a schematic configuration of a measurement system 1C according to the fourth embodiment. In the following description, parts having the same functions as those described in the first, second and third embodiments are given the same names and symbols, and specific descriptions of the functions are omitted.

[0087] The measurement system 1C is different from the third embodiment in the method of measuring the length of the pile 200. The measurement system 1C includes an imaging unit 10, an acquisition unit 50, and an information processing device 20C.

[0088] The acquisition unit 50 acquires position information of the gripper 120 (hereinafter referred to as "grip position"). The gripper position includes at least a position in the vertical direction. For example, the gripper position is information on the distance from the ground to the gripper 120. In the third embodiment, the acquisition unit 50 is provided in the pile driver 100, but is not limited to this and may be provided in the information processing device 20C.

[0089] The information processing device 20C includes a measuring unit 21, a reading unit 40, a calculation unit 51, a storage unit 22C, a pile number acquisition unit 30, a reception unit 31, a collation unit 32C, and an output unit 23C. These components are realized, for example, by a hardware processor such as a CPU executing a program (software). In addition, some or all of these components may be realized by hardware (including circuitry) such as an LSI, ASIC, FPGA, or GPU, or may be realized by cooperation between software and hardware. The program may be stored in a storage device such as an HDD or flash memory (a storage device having a non-transient storage medium) in advance, or may be stored in a removable storage medium such as a DVD or CD-ROM (a non-transient storage medium), and may be installed in the storage device by mounting the storage medium in a drive device. The storage device is, for example, configured of an HDD, a flash memory, an EEPROM, a ROM, or a RAM.

[0090] The calculation unit 51 acquires the gripping unit position from the acquisition unit 50 via the communication network NW. The calculation unit 51 calculates the pile length of the pile 200 gripped by the gripping unit 120 based on the gripping unit position acquired by the acquisition unit 50. For example, when the bottom end of the pile 200 is in contact with the ground, the calculation unit 51 calculates the gripping unit position as the pile length of the pile 200. Here, the calculation unit 51 may determine whether or not the bottom end of the pile 200 is in contact with the ground based on the captured image.

[0091] The operator of the pile driver 100 may operate the operating device in the driver's seat to control the bottom end of the pile 200 to be in contact with the ground before the gripper position is acquired by the acquisition unit 50. After that, the acquisition unit 50 may start acquiring the gripper position.

[0092] When the bottom end of the pile 200 is not in contact with the ground, the imaging unit 10 captures an image of the area between the bottom end of the pile 200 and the ground. The calculation unit 51 may measure the distance between the bottom end of the pile 200 and the ground (hereinafter referred to as the "separation distance") based on the captured image. In this case, the calculation unit 51 calculates the difference between the gripping unit position and the separation distance to calculate the pile length of the pile 200 gripped by the gripping unit 120.

[0093] Storage unit 22C stores information similar to the information stored in storage unit 22A.

[0094] The collation unit 32C collates information including the diameter information measured by the measurement unit 21, the pile reading information output from the reading unit 40, and the pile length calculated by the calculation unit 51 with the registration information associated with the pile number accepted by the acceptance unit 31. The collation unit 32C outputs the collation result to the output unit 23C.

[0095] The output unit 23C outputs the collation result obtained by the collation unit 32C to an external device, etc. The output mode of the output unit 23C is similar to that of the output unit 23A, and therefore a description thereof will be omitted.

[0096] The following is a diagram for explaining the flow of the measurement method according to the fourth embodiment. Fig. 15 is a diagram for explaining the flow of the measurement method according to the fourth embodiment.

[0097] The information processing device 20C receives, at the receiving unit 31, a pile number indicating a driving position where the pile 200 will be driven by the pile driver 100 (step S401).

[0098] The information processing device 20C acquires a captured image from the imaging unit 10 (step S402). Note that, in step S402, the information processing device 20C may acquire a captured image of the pile 200 when the pile driver 100 moves the pile 200 vertically downward while rotating it. Note that step S401 may be executed after step S402, or may be executed simultaneously with step S402.

[0099] The information processing device 20C measures at least diameter information based on the captured image acquired in step S402 (step S403). The information processing device 20C reads the pile information 400 printed on the pipe surface of the pile 200 while the pile 200 is being held by the gripping unit 120 or while the pile 200 is being rotated and buried, and obtains pile reading information such as the steel pipe thickness, steel pipe material, pile length, and lot number from the read pile information 400 (step S404).

[0100] For example, the pile driver 100 moves the gripper 120 vertically downward until the bottom end of the pile 200 touches the ground. When the bottom end of the pile 200 touches the ground, the acquisition unit 50 acquires the gripper position. The acquisition unit 50 transmits the acquired gripper position to the information processing device 20C. The information processing device 20C calculates the gripper position acquired from the acquisition unit 50 as the pile length (step S405). Note that in the fourth embodiment, at least the gripper position needs to be used to calculate the pile length, and other information such as a captured image may also be used.

[0101] The information processing device 20C compares the diameter information measured in step S403, the pile reading information acquired in step S404, and the pile length acquired in step S405 with the registered specifications associated with the pile number accepted by the acceptance unit 31 (step S406). If the comparison is successful, the information processing device 20C outputs information indicating the success of the comparison by displaying it on the display screen (step S407). If the comparison is unsuccessful, the information processing device 20C outputs information indicating the failure of the comparison by displaying it on the display screen (step S408). Therefore, if the comparison is successful, the user executes driving of the pile 200 held by the gripping unit 120. If the comparison is unsuccessful, the user checks the specifications of the pile 200 held by the gripping unit 120 and replaces it with a pile 200 of appropriate specifications.

[0102] As described above, the measurement system 1C of the fourth embodiment has the same effects as the first, second and third embodiments, and can also calculate the total length of the pile 200 when the total length of the pile 200 cannot be captured on the captured image.

[0103] In addition, the output unit 23C may output, in addition to the results of the comparison by the comparison unit 32C, diameter information measured by the measurement unit 21, pile reading information obtained by the reading unit 40, and pile length calculated by the calculation unit 51 in a manner similar to that of the output unit 23.

[0104] Furthermore, in the measurement system 1C of the fourth embodiment, the configuration of the reading unit 40 may be omitted.

[0105] Fifth embodiment 16 is a diagram showing an example of a schematic configuration of a measurement system 1D according to the fifth embodiment. In the following description, parts having the same functions as those described in the first, second, third and fourth embodiments are given the same names and symbols, and specific descriptions of the functions are omitted.

[0106] The measurement system 1D differs from the second embodiment in that it includes a configuration for executing a pile number confirmation process for confirming whether the marking of the pile numbers shown in Fig. 10 is in accordance with the pile plan and the construction plan. The marking of the pile numbers shown in Fig. 10 may be performed, for example, by a prime contractor while checking the pile plan and the construction plan. However, the prime contractor may mark a wrong pile number (label 310) at a certain concrete driving position. Therefore, the measurement system 1D judges whether the pile number marked at the concrete driving position is correct.

[0107] The measurement system 1D includes an imaging unit 10 and an information processing device 20D.

[0108] The information processing device 20D acquires a captured image from the imaging unit 10 via the communication network N, similar to the first embodiment. The installation position of the information processing device 20D is similar to the first embodiment. The information processing device 20D is, for example, a computer or a smart device, similar to the first embodiment.

[0109] The information processing device 20D includes a measuring unit 21, a storage unit 22D, a pile number acquiring unit 30D, a distance measuring unit 60, a reception determining unit 61, a reception unit 31, a matching unit 32D, and an output unit 23D. The matching unit 32D has the same configuration as the matching unit 32A. The output unit 23D has the same configuration as the output unit 23A. These components are realized by, for example, a hardware processor such as an APU executing a program (software). In addition, some or all of these components may be realized by hardware (including circuitry) such as an LSI, ASIA, FPGA, or GPU, or may be realized by cooperation between software and hardware. The program may be stored in a storage device such as an HDD or flash memory (a storage device having a non-transient storage medium) in advance, or may be stored in a removable storage medium such as a DVD or AD-ROM (a non-transient storage medium), and may be installed in the storage device by mounting the storage medium in a drive device. The storage device is, for example, configured by an HDD, flash memory, EEPROM, ROM, or RAM.

[0110] The storage unit 22D stores information similar to that stored in the storage unit 22A. In addition, the storage unit 22D stores in advance, for each pile number, the distances (hereinafter referred to as "distance setting values") between the driving position indicated by the pile number and two or more fixed points installed at the site. In this embodiment, two fixed points 500, 510 are installed at the site. The positions of the fixed points 500, 510 are known and are reflected in the pile setting plan and the construction plan. Therefore, as shown in FIG. 17, the storage unit 22D stores in advance, for each pile number, a distance setting value L1 which is the distance between the driving position and the fixed point 500, and a distance setting value L2 which is the distance between the driving position and the fixed point 510. The distance setting values ​​L1, L2 may be set by the information processing device 20D or a device other than the information processing device 20D based on the pile setting plan and the construction plan, or may be set by the construction manager.

[0111] The pile number acquisition unit 30D has the same function as the pile number acquisition unit 30. For example, a label 310 indicating a pile number is attached to a reinforcing bar 300 embedded in each driving position at a construction site as shown in Fig. 10. The pile number acquisition unit 30D acquires the pile number indicated on the label 310 shown in an arbitrary label image input from the imaging unit 10 or a camera other than the imaging unit 10, based on the arbitrary label image input from the imaging unit 10 or a camera other than the imaging unit 10.

[0112] The distance measurement unit 60 measures the distance between the concrete pouring position (target concrete pouring position) indicated by the pile number acquired by the pile number acquisition unit 30D and two or more fixed points installed at the site, based on an image including the target concrete pouring position and two or more fixed points. For example, the distance measurement unit 60 acquires an image including at least the target concrete pouring position and the fixed points 500, 510 from the imaging unit 10. The distance measurement unit 60 measures the distance between the target concrete pouring position and the fixed point 500 (hereinafter, "distance measurement value L1'") and the distance between the target concrete pouring position and the fixed point 510 (hereinafter, "distance measurement value L2'") based on the image.

[0113] The acceptance determination unit 61 determines whether or not to accept the pile number acquired by the pile number acquisition unit 30D in the acceptance unit 31 based on the distance measurement values ​​L1', L2' measured by the distance measurement unit 60D. The acceptance determination unit 61 reads the distance setting values ​​L1, L2 corresponding to the pile number acquired by the pile number acquisition unit 30D from the storage unit 22D, and allows the acceptance of the pile number acquired by the pile number acquisition unit 30D if the read distance setting values ​​L1, L2 match the distance measurement values ​​L1', L2' measured by the distance measurement unit 60. On the other hand, if the read distance setting values ​​L1, L2 do not match the distance measurement values ​​L1', L2' measured by the distance measurement unit 60, the acceptance determination unit 61 prohibits the acceptance of the pile number acquired by the pile number acquisition unit 30D. If the distance setting values ​​L1, L2 do not match the distance measurement values ​​L1', L2', it indicates that the label 310 with the wrong pile number may have been applied to the target concrete driving position.

[0114] The pile number confirmation process will be described below with reference to Fig. 18. Fig. 18 is a diagram for explaining the pile number confirmation process. Fig. 18(a) is a diagram reflecting two fixed points 500, 510 on a pile plan. Fig. 18(b) is a diagram showing that two fixed points 500, 510 are installed at the site, and labels 310 are attached to each casting position.

[0115] In FIG. 18(b), the pile number "9" is mistakenly assigned to the concrete driving position that is actually assigned the pile number "4". When the user sets the concrete driving position of the pile number "9" as the concrete driving target position, the user causes the imaging unit 10 to capture the label 310 of the concrete driving target position. This label image is transmitted to the information processing device 20D via the communication network N. The user also causes the imaging unit 10 to capture an image (hereinafter referred to as a "site image") including at least the concrete driving target position and the two fixed points 500, 510. This site image may be the same as the label image. The pile number acquisition unit 30D acquires the pile number "9" from the label image. The distance measurement unit 60 measures the distance between the concrete driving position of the pile number "9" acquired by the pile number acquisition unit 30D and each of the fixed points 500, 510 based on the site image. The distance measurement unit 60 outputs to the reception / judgment unit 61 the distance measurement value L1', which is the distance between the driving position of the pile number "9" and the fixed point 500, and the distance measurement value L2', which is the distance between the driving position of the pile number "9" and the fixed point 510.

[0116] The reception / determination unit 61 reads the distance setting values ​​L1 and L2 corresponding to the pile number "9" acquired by the pile number acquisition unit 30D from the storage unit 22D. The read distance setting values ​​L1 and L2 are the distances shown in FIG. 18(a) on the pile plan. The reception / determination unit 61 determines whether the read distance setting value L1 and the distance measurement value L1' match, and whether the read distance setting value L2 and the distance measurement value L2' match. In the example shown in FIG. 18, the label 310 of the pile number "9" is attached to an incorrect casting position. Therefore, the reception / determination unit 61 detects at least one of the following: the distance setting value L1 and the distance measurement value L1' do not match, and the distance setting value L2 and the distance measurement value L2' do not match. When the reception / determination unit 61 detects at least one of the following: the distance setting value L1 and the distance measurement value L1' do not match, and the distance setting value L2 do not match. When the reception / determination unit 61 detects at least one of the following: the reception / determination unit 61 prohibits the reception unit 31 from accepting the pile number "9". When at least any one of the inconsistencies is detected, the output unit 23D may output, to an external device or the like, information indicating that the pile number "9" has been assigned to an incorrect driving position.

[0117] As described above, the measurement system 1D of the first embodiment has the same effects as the first, second, third and fourth embodiments, and can also confirm whether the pile number label 310 installed on-site is correct.

[0118] Although the present invention has been described above using the embodiments, the technical scope of the present invention is not limited to the scope described in the above embodiments. It is clear to those skilled in the art that various modifications and improvements can be made to the above embodiments. It is clear from the claims that such modifications and improvements can also be included in the technical scope of the present invention.

[0119] Throughout the specification, when a part is described as "comprising," "having," or "including" certain elements, this does not mean that it excludes other elements, but that it may further include other elements, unless specifically stated to the contrary.

[0120] Furthermore, the term "part" used in the specification means a unit that processes at least one function or operation, which may be embodied as hardware or software, or as a combination of hardware and software.
