Description

Technical Field

[0001] This invention relates to a storage medium storing measurement assistance programs, a measurement assistance device, a measurement assistance method, and a measurement assistance system. Background Technology

[0002] During the construction of routes, a construction plan is created, taking into account the volume of excavation and backfilling. When creating the construction plan, the current condition of the construction site is measured to serve as a reference. Furthermore, an as-built shape observation is conducted after construction is completed. The measurement of the current condition includes center stake distance observation, which calculates the horizontal and vertical distances from the center stake (center point) set as the centerline of the route. Conversely, in the as-built shape observation, the constituent points are measured, the horizontal and vertical distances are calculated, and compared with the design information.

[0003] Such center pile distance observations or completed shape observations are typically performed using optical devices such as total stations or GNSS devices. Furthermore, the following technique is proposed: a portable information processing device reads in design information containing constituent point data, displays plan views, cross-sectional views, and numerical information on a display unit, and assists the measuring device using a total station or GNSS device (e.g., see Patent Document 1, Non-Patent Document 1, etc.).

[0004] The difference between center pile distance observation and finished shape observation lies in whether the reference point used for distance calculation is the center point or the constituent point, but they are similar in that they determine the horizontal and vertical distances between the reference point and the observation point in order to obtain design information.

[0036] (Implementation Method)

[0037] (Overall System Structure)

[0038] Figure 1 This is a schematic diagram of the overall measurement assistance system (hereinafter simply referred to as the "system") 100 according to an embodiment of the present invention. Figure 2 This is a block diagram of system 100. System 100 includes a position acquisition device 30 and a measurement auxiliary device 50.

[0039] (Design Information)

[0040] Before describing the structure of system 100, the design information used in this system will be explained. Figure 3This is a diagram illustrating the design information used in this system 100. The design information includes, for example, information from a route design diagram created in an absolute coordinate system, required for the construction of routes, etc. The design information includes centerline data representing the centerline CL of the route. Furthermore, it includes centerpoint data representing centerpoints CP0, CP1, CP2, ... set at specified intervals (e.g., 20m intervals) on the centerline CL. Centerpoints are the points where center stakes are set on site.

[0041] The design information includes cross-sectional data, which represents each cross-section (hereinafter also simply referred to as "section") No.0, No.1, No.2, etc., that contains center points CP0, CP1, CP2, etc. and is orthogonal to the centerline. On each cross-section, constituent points are defined, for example, as on section No.0, constituent points P01 to P04. Constituent points are, for example, stakes marked on-site, such as points defining the width of a road. Along the route direction, positions equidistant from the center point are defined in each cross-section, for example, P01, P11, P21, etc.

[0042] (Composition of the position acquisition device 30)

[0043] The position acquisition device 30 consists of a measuring device 10 and a measured device 40.

[0044] The measuring device 10 is a total station (electronic distance measuring and angle measuring instrument). The measuring device 10 is set up at a known point via a tripod 2. Alternatively, the coordinates can be known after the measuring device 10 is set up, for example, by resection. Furthermore, the coordinate data of the measuring device 10 is input into the measuring aid device 50 and saved to the terminal storage unit 53.

[0045] The measuring device 10 has, in appearance, a base 5 mounted on the leveling section 3, a bracket 7 that rotates horizontally about axis H-H on the base 5, and a telescope 9 that rotates vertically about axis V-V on the bracket 7. The control and calculation unit 23, which will be described later, is housed in the bracket 7.

[0046] The measuring device 10 has automatic aiming and automatic tracking functions, and a range-measuring optical system and a tracking optical system (not shown) are housed in the telescope 9. The configuration of the range-measuring optical system and the tracking optical system is known in the past. In the measuring device 10, the range-measuring light and the tracking light are illuminated throughout the entire circumference by the coordination of the horizontal rotation of the bracket 7 and the vertical rotation of the telescope 9.

[0047] like Figure 2As shown, the measuring device 10 includes a ranging unit 11, a tracking unit 12, a horizontal rotation drive unit 13, a vertical rotation drive unit 14, a horizontal angle detector 15, a vertical angle detector 16, a communication unit 17, a tilt sensor 18, a storage unit 19, an operation unit 21, a display unit 22, and a control and calculation unit 23.

[0048] The ranging unit 11 uses the above-mentioned ranging optical system to emit ranging light, receives the reflected light from the target 41 provided by the measuring device 40, and performs automatic aiming and ranging on the target 41.

[0049] The tracking unit 12 emits tracking light using the aforementioned tracking optical system, captures the position of the target 41 based on the reflected light from the target 41, and automatically tracks the target 41 when the target 41 moves.

[0050] The horizontal rotation drive unit 13 is a motor installed in the base part 5. The horizontal rotation drive unit 13 causes the bracket part 7 to rotate about axis H-H relative to the base part 5. The vertical rotation drive unit 14 is a motor installed in the bracket part 7. The vertical rotation drive unit 14 causes the telescope 9 to rotate about axis V-V.

[0051] The horizontal angle detector 15 and the vertical angle detector 16 are rotary encoders. The horizontal angle detector 15 detects the angle of the bracket 7 around the axis H-H, and the vertical angle detector 16 detects the angle of the telescope 9 around the axis V-V. As a result, the horizontal angle detector 15 and the vertical angle detector 16 constitute an angle measuring part for measuring the angle of the target 41.

[0052] The communication unit 17 is a communication control device that connects the measuring device 10 and the measuring auxiliary device 50 via wired or wireless means. As the communication standard for implementing the communication unit 17, Wi-Fi (registered trademark) or 4G (4th generation mobile communication system), which are wireless LAN standards, can also be used. Alternatively, short-range wireless communication standards such as Bluetooth (registered trademark) or infrared communication can also be used.

[0053] The tilt sensor 18 is a bubble tube type, electrostatic capacitance type, or other tilt sensor, and is fixed on the upper surface of the rotation shaft (not shown) of the base 5. The value of the tilt sensor 18 is read when the rotation shaft of the horizontal rotation drive unit 13 is rotated forward and backward once each, and the leveling unit 3 is adjusted based on the deviation during the forward and reverse rotation.

[0054] The storage unit 19 is a storage medium that stores, saves, and transmits information in a form that can be processed by the control and arithmetic unit 23, such as an HDD (Hard Disc Drive) or flash memory. The storage unit 19 stores measured data and programs used to control various processes in the arithmetic unit.

[0055] The operation unit 21 consists of multiple buttons provided on the outer surface of the bracket unit 7. Through the operation unit 21, various information related to the operation of the measuring device 10 can be input.

[0056] The display unit 22 is a liquid crystal display provided on the outer surface of the bracket unit 7, which displays various information related to measurement.

[0057] The control and arithmetic unit 23 is a microcomputer that integrates a CPU (Central Processing Unit), ROM (Read-Only Memory), RAM (Random Access Memory), etc., into an integrated circuit. The control and arithmetic unit 23 is connected to various parts of the measuring device 10.

[0058] The control and arithmetic unit 23 reads the program used to execute various functions of the measuring device 10 from the storage unit 19 or RAM, controls each part of the measuring device 10, and executes various functions such as automatic tracking and distance / angle measurement. In addition, it processes the data obtained through distance / angle measurement to obtain the position information (position coordinates) of the target 41.

[0059] In addition, the control and calculation unit 23 communicates with the measurement auxiliary device 50 via the communication unit 17, executes processing according to the commands of the measurement auxiliary device 50, and sends the position information of the measured device to the measurement auxiliary device 50.

[0060] The measuring device 40 has a target 41 and a columnar support member 42 that supports the target 41.

[0061] Target 41 is a so-called omnidirectional prism composed of multiple triangular pyramidal prisms arranged radially, but it is not limited to this. Target 41 reflects incident light back in the opposite direction to the incident direction.

[0062] The length H1 of the support member 42 from its front end to the center O1 of the target 41 is known. The support member 42 is equipped with a level (not shown) to enable it to be set vertically. For the target 41, which is set vertically at the observation point P via the support member 42, a measuring device 10 set at the known point is used to measure distance / angle. By subtracting the length H1 of the support member 42 from the three-dimensional coordinates of the center O1 obtained from the obtained distance / angle data, the three-dimensional coordinates of the observation point P can be obtained as the position information of the measured device 40.

[0063] As another embodiment of the location acquisition device 30, a GNSS measuring device can be used. In this case, a GNSS receiving device capable of communicating with the measuring assistance device 50 is used as the measured device 40 to measure the current position of the measured device 40.

[0064] (Composition of the measurement auxiliary device)

[0065] The measurement assistance device 50 is a portable information processing device capable of communicating with the location acquisition device 30. The measurement assistance device 50 may be implemented as, for example, a mobile phone, smartphone, tablet computer, PDA, data collector, or portable computer terminal.

[0066] The measurement auxiliary device 50 includes a terminal screen unit 51, a terminal operation unit 52, a terminal storage unit 53, a terminal communication unit 54, and a terminal control unit 55.

[0067] The terminal screen unit 51 is, for example, a touch panel-type liquid crystal display integrated with the terminal operation unit 52. The terminal screen unit 51 can display images corresponding to the work content, such as the observation screen 60 and the cross-section specification method selection screen 80.

[0068] The terminal storage unit 53 stores various programs and data freely in a storage medium. The terminal storage unit 53 is, for example, an HDD. Alternatively, the terminal storage unit 53 could also be an optical disc drive such as a CD (Compact Disc) drive. The terminal storage unit 53 stores communication programs, image display programs for displaying work content and communication content on the terminal screen unit 51, and various programs for executing center stake distance observation and completed shape observation.

[0069] Furthermore, the terminal storage unit 53 stores the coordinates of the measuring device 10, the initial setting information of the height H1 of the target 41, and design information. It also stores the measurement data of the target 41 received from the measuring device 10, the results of center pile distance observation, and the results of finished shape observation.

[0070] The terminal communication unit 54 is a communication control device that can communicate with the measurement device 10 via the communication unit 17 of the measurement device 10, and has the same communication specifications as the communication unit 17.

[0071] The terminal control unit 55 is a control unit that includes at least a CPU and memory (ROM, RAM). Based on input signals from the terminal communication unit 54, terminal operation unit 52, etc., the terminal control unit 55 controls the measurement auxiliary device 50 and the measurement device 10. The terminal control unit 55 retrieves and executes programs stored in RAM or the terminal storage unit 53.

[0072] The terminal control unit 55, as a functional unit, includes a design information reading unit 551, a position information acquisition unit 552, a view display unit 553, a section specification method selection unit (hereinafter referred to as "specification method selection unit") 554, a reference point selection unit 555, a distance calculation unit 556, and a measurement information display unit 557.

[0073] The design information reading unit 551 reads the design information stored in the terminal storage unit 53. Alternatively, it can receive and read the design information stored in an external storage device via the terminal communication unit 54.

[0074] The position information acquisition unit 552 receives measurement data of the target 41 measured by the measuring device 10 at a predetermined period via the terminal communication unit 54. The position information acquisition unit 552 acquires the position information of the measured device 40 (observation point) in the absolute coordinate system based on the coordinates of the measuring device 10 stored in the terminal storage unit 53 and the length H1 of the support member 42.

[0075] The view display unit 553 generates, based on the design information, a plan view 61 showing the centerline CL of the route from directly above, and a cross-sectional view 62 connecting the constituent points in any cross-section, and displays them on the observation screen 60 of the terminal screen unit 51. Figure 4 Furthermore, during observation, based on the position information of the measured device 40 acquired by the position information acquisition unit 552, the position of the measured device 40 is displayed on a plan view, and the display is updated according to the intervals in which the position information is acquired. Figure 4 ).

[0076] The method selection unit 554 displays a cross section selection screen 80 on the terminal screen unit 51. The cross section selection method is selected by the operator through input, for example from a cross section pre-specified by the operator (hereinafter referred to as "specified cross section"), a cross section closest to the current position of the measured device 40 (hereinafter referred to as "closest cross section"), or an interpolated cross section generated as a cross section containing any point observed as the current position of the measured device and including the center line CL (hereinafter referred to as "arbitrary cross section").

[0077] The reference point selection unit 555 selects a reference point from the design information based on the operator's selection. Here, the reference point is a point used to measure horizontal and vertical distances. For example, the operator can switch reference points by tapping the reference point switching buttons 63a and 63b displayed on the observation screen 60 of the terminal screen unit 51. Even if the reference point switching moves the section in the route direction, the position in the direction orthogonal to the route will be saved. Specifically, for example, the reference point P03 (adjacent to the right of the centerline CL) is selected. Figure 3 When selected as the reference point, if section No.1 is specified, the constitutive point P13 adjacent to the right of the centerline CL in section No.1 is selected.

[0078] The distance calculation unit 556 calculates the horizontal distance and the vertical distance from the selected reference point in the cross-section specified by the cross-section specification method selected by the specified method selection unit 554, based on the position information of the current position of the measured device 40 and the designed position information of the selected reference point.

[0079] Figure 5 (A) to Figure 5 (C) are diagrams illustrating the method of distance calculation in each cross-section specification method. The black circles in the diagrams are the points designated as the reference points. That is, for example, when the specified cross-section is selected as the cross-section specification method, cross-section No. 0 is specified as the specified cross-section, and the center point CP0 is selected as the reference point, as Figure 5 (A) shows, the horizontal distance d1 and the vertical distance d2 between the center point CP0 in cross-section No. 0 and the measured device 40 are calculated.

[0080] When the closest cross-section is selected as the cross-section specification method, the distance calculation unit 556 compares the distances between the measured device 40 and the two cross-sections sandwiching the measured device 40 in the route direction, and designates the closer cross-section as the closest cross-section. Then, based on the position information of the measured device 40 and the position information of the reference point in the closest cross-section, the horizontal distance and the vertical distance between the reference point and the measured device 40 are calculated.

[0081] For example, when the center point CP0 (center points CP0, CP1, CP2,...) is selected as the reference point, for example, as Figure 5 (B) shows, when the measured device 40 is between cross-section No. 0 and cross-section No. 1, the distance calculation unit 556 first calculates the distances d3 and d4 between the measured device 40 and cross-section No. 0 and cross-section No. 1 respectively, and compares the distances d3 and d4. Here, since d3 < d4, the closer cross-section No. 1 is designated as the closest cross-section. Then, the horizontal distance d5 and the vertical distance d6 between the center point CP1 in cross-section No. 1 and the measured device 40 are calculated.

[0082] When the arbitrary cross-section is selected as the cross-section specification method and the center point CP0 (center points CP0, CP1, CP2,...) is selected as the reference point, the distance calculation unit 556, as Figure 5 (C) shows, generates the interpolation cross-section No. X that includes the current position (observation point) of the measured device 40 and is orthogonal to the center line.

[0083] The generation of the interpolation cross-section No. X is performed by interpolation based on the ratio of the distances between the current position of the measured device 40 and the closest cross-sections No. 0 and No. 1 sandwiching the current position of the measured device 40. Then, the center point CP in cross-section No. X is calculated XUsing the center point CPx as a reference point, calculate the horizontal distance d7 and the vertical distance d8 between the measured device 40 and the center point CPx. Furthermore, while the above description calculates the horizontal distance in the transverse direction, the horizontal distance in the route direction can also be calculated simultaneously.

[0084] The measurement information display unit 557 displays the specified section number, the selected reference point, the calculated horizontal distance, and the vertical distance, etc., as measurement information on the observation screen 60 of the terminal screen unit 51. Furthermore, the measurement information display unit 557 can also display measurement information such as the forward and backward horizontal distances on the observation screen 60.

[0085] The functions of each functional unit can be implemented by circuitry or by executing a program. Furthermore, when implemented by a program, the program can be stored on a computer-readable storage medium such as a disk, floppy disk, optical disk, CD, Blu-ray disc, or DVD.

[0086] (Observational footage)

[0087] Figure 4 This describes one example of an observation screen 60 displayed on the terminal screen unit 51 during observation execution. In the observation screen 60, a plan view 61 and a cross-sectional view 62 generated by the view display unit 553 are displayed side-by-side. A centerline CL is displayed at the center of the cross-sectional view 62.

[0088] Furthermore, in plan view 61, a marker M1 indicating the position of the measured device 40 and a marker M3 indicating the selected reference point are shown. In cross-sectional view 62, a marker M2 indicating the position of the measured device 40 and a marker M4 indicating the selected reference point are shown. Additionally, in observation screen 60, reference point switching buttons 63 (63a, 63b) for selecting a reference point are displayed. Reference point switching buttons 63 are used to move the selected reference point one position to the right (63b) or left (63a) by tapping.

[0089] Furthermore, on the observation screen 60, measurement information displays 64a to 64f are displayed, showing the measurement information calculated by the measurement information display unit 557. Measurement information displays 64a to 64f, for example, indicate the section number, the designated reference point, the horizontal distance of the measured device 40 from the designated section in the longitudinal direction, the horizontal distance of the measured device 40 from the selected reference point in the left-right direction orthogonal to the longitudinal direction of the route, the vertical distance of the measured device 40 from the designated reference point, and the target height, i.e., the length H1 from the front end of the support member 42 to the center O1 of the target 41.

[0090] In addition, the observation screen 60 can also display a directional display 65 indicating the cardinal directions of the plan 61 (north, south, east, west) and a scale display 66 indicating the scale. Furthermore, the observation screen 60 can also display function icons 67a, 67b, 67c, etc., used to assist in various surveying operations.

[0091] In addition, the observation screen 60 displays a tracking start button 68 for commanding the measuring device 10 to start and stop tracking and observation, and observation and confirmation buttons 69 and 71 for stopping the update of the measurement information display and fixing the value.

[0092] In addition, the cross-sectional view 62 can change its relative position to the plan view 61 simultaneously displayed on the terminal screen 51 according to the instructions of the terminal operation unit 52. Specifically, its position can be freely changed within the frame via touch panel operation. Furthermore, the display / display of the cross-sectional view 62 can be toggled.

[0093] (Measurement Auxiliary Method 1)

[0094] Figure 6 This is a flowchart illustrating an example of a measurement assistance method that assists in the observation of center pile distance and finished shape using the measurement assistance device 50 of this embodiment. Furthermore, Figure 7 (A) is the menu screen 90 used to start this measurement assistance method. For example... Figure 7 As shown, this method is displayed as a menu item such as Road Survey.

[0095] The measuring device 10 is set at a known point and is configured to automatically track the target 41.

[0096] If Figure 7 If you tap the route measurement menu 91 in (A) to start processing, then in step S01, the design information reading unit 511 will read the design information stored in the terminal storage unit 53.

[0097] Next, in step S02, the method selection unit 554 displays the cross-section selection screen 80 on the terminal screen unit 51. Then, in step S03, the operator selects a selection method from the specified cross-section, the closest cross-section, and any cross-section from the screen.

[0098] Figure 7 (B)~ Figure 7 (D) is an example of selecting screen 80 using the section specification method. When selecting any section, such as... Figure 7(B) Select “Use interpolated X-section” and select any section by tapping the forward arrow 81, then move to the observation screen 60.

[0099] Furthermore, when choosing the closest cross-section, such as Figure 7 (C) Deselect the above selection and select "Automatic X-section Station" (use the closest section). Select the closest section by tapping the forward arrow 81 and move to the observation screen 60.

[0100] Furthermore, when selecting a specific cross-section, by means of, Figure 7 (D) By deselecting the above selection, you can select a specific section. Alternatively, after selecting a specific section, you can select the specific section and move to the observation screen 60 by tapping the forward arrow 81.

[0101] If a specified section is selected in step S03, in step S04, as described above, the operator will specify the specified section, for example, as section No. 1.

[0102] Next, in step S05, the reference point selection unit 555 selects a reference point based on the operator's selection. Specifically, by... Figure 8 (A) Clicking the reference point switching button 63b displayed on the observation screen 60 will set the reference point to be at the center point CP1, indicated by markers M3 and M4, as shown in Figure 60. Figure 8 (B) is shown as a reference point shifted to the right, forming point P13. Thus, the reference point used for calculating horizontal and vertical distances can be changed to the forming point and center point.

[0103] Next, in step S06, if observation is started by tapping the observation start button, the measuring device 10 sends the measurement data of the target 41 to the measuring aid device 50 at a predetermined period. Additionally, although not included... Figure 6 In the flowchart, the view display unit 553 displays the plan view 61 and cross-sectional view 62 generated based on the design information on the observation screen 60 of the terminal screen unit 51. Whenever the position information acquisition unit 552 acquires the current position of the measured device 40, the view display unit 553 updates the display of markers M1 and M2.

[0104] Next, in step S07, the position information acquisition unit 552 acquires the measurement data of the target 41 at a predetermined period and acquires the position information of the measured device 40.

[0105] Next, in step S08, the distance calculation unit 556 calculates the horizontal distance and the vertical distance between the reference point in the specified cross section and the measured device 40.

[0106] Next, in step S09, the measurement information display unit 557 displays the horizontal distance and vertical distance on the observation screen 60 as measurement information.

[0107] Then, in step S10, steps S07 to S10 are repeated according to the operator's instructions until the observation is determined to be complete. The process ends when the observation is determined to be complete.

[0108] On the other hand, if the closest cross section is selected in step S03, the reference point selection unit 555 selects a reference point in step S14 in the same way as in step S05.

[0109] Next, in step S15, if observation begins, the measuring device 10 sends the measurement data of the target 41 to the measuring auxiliary device 50 at a predetermined period, similar to step S06.

[0110] Next, in step S16, the position information acquisition unit 552 acquires the measurement data of the target 41 at a predetermined period and acquires the position information of the current position of the measured device 40.

[0111] Next, in step S17, the distance calculation unit 556 specifies the closest cross section to the current position of the measured device 40.

[0112] Next, in step S18, the distance calculation unit 556 calculates the horizontal and vertical distances between the measured device 40 and the reference point in the specified closest cross section.

[0113] Next, in step S19, similar to step S09, the measurement information display unit 557 displays the horizontal distance and vertical distance on the observation screen 60 as measurement information.

[0114] Then, in step S20, steps S16 to S20 are repeated according to the operator's instructions until the observation is determined to be over. The process ends when the observation is determined to be over.

[0115] On the other hand, if an arbitrary cross section is selected in step S03, the reference point selection unit 555 selects a reference point in step S24 in the same way as in step S05.

[0116] Next, in step S25, if observation begins, the measuring device 10 sends the measurement data of the target 41 to the measuring auxiliary device 50 at a predetermined period, similar to step S06.

[0117] Next, in step S26, the position information acquisition unit 552 acquires the measurement data of the target 41 at a predetermined period and acquires the position information of the measured device 40.

[0118] Next, in step S27, the distance calculation unit 556 generates a cross section at the position of the measured device 40 as an interpolation cross section, and designates the interpolation cross section as a designated cross section.

[0119] Next, in step S28, the distance calculation unit 556 calculates the horizontal and vertical distances between the reference point on the interpolation section and the position of the measured device 40.

[0120] Next, in step S29, similar to step S09, the measurement information display unit 557 displays the horizontal distance and vertical distance on the observation screen 60 as measurement information.

[0121] Then, in step S30, steps S26 to S30 are repeated according to the operator's instructions until the observation is determined to be complete. The process ends when the observation is determined to be complete.

[0122] Thus, in the measurement assistance system 100 of this embodiment, since the reference point used as the basis for calculating the horizontal and vertical distances from the observation point (the current position of the measured device) can be either the center point or the constituent point included in the design information, the measurement assistance device 50 can execute two observation methods with a single menu: center stake distance observation for measuring the horizontal and vertical distances from the center point, and finished shape observation for measuring the horizontal and vertical distances from the center point and the constituent point.

[0123] Based on the above configuration, users only need to master the operation of one menu to use both observation methods, thus improving convenience. Furthermore, when switching between two observation methods while executing them, it is possible to execute them within a single program without switching programs, reducing the operational burden. Moreover, from the manufacturer's perspective, since two similar programs can be unified, the storage capacity can be reduced.

[0124] Furthermore, even when it is necessary to measure a cross-section defined in the design as a designated cross-section, there are situations where measurement is difficult on-site due to obstacles or other factors. In this embodiment, since the closest cross-section can be used as the designated cross-section, in cases where measurement at the cross-section defined in the design is difficult as described above, the horizontal and vertical distances can be measured as approximate values ​​by measuring the horizontal and vertical distances at the closest cross-section.

[0125] Furthermore, center points are typically set at predetermined intervals, such as 20m intervals. However, in actual field conditions, there are points where the route makes sharp turns (change points) or where the width needs to be altered. In such cases, center point distance observations need to be performed outside of the cross-sections specified in the design. In this embodiment, an interpolation cross-section is generated at any location as a designated cross-section. Horizontal and vertical distances can be obtained by referring to the center point (or constituent point) on this interpolation cross-section, allowing for necessary observations even in locations without a designated cross-section.

[0126] Furthermore, in this embodiment, the calculated horizontal and vertical distance values ​​are updated every time the current position of the measured device is obtained at a predetermined period. However, according to the operator's preference, the display update of the calculated values ​​can be temporarily stopped by a simple action of tapping the confirmation button. Based on the above configuration, even when the measurement time is spent due to value movement, measurements can be performed efficiently with appropriate accuracy.

[0127] (Measurement Auxiliary Method 2)

[0128] Figure 9 This is a flowchart illustrating another example of a measurement assistance method that assists in the execution of center pile distance observation and finished shape observation using the measurement assistance device 50 of this embodiment.

[0129] In this method, Figure 6 The steps S09 and S10, S19 and S20, and S29 and S30 of the flowchart can be executed. Figure 9 The process is described in the flowchart. An example is given where a specific cross-section has been selected.

[0130] After step S09 is completed, in step S41, if the observation and confirmation button 69 of the observation screen 60 is tapped, in step S42, the measurement information display unit 557 is fixed in its current display state.

[0131] Next, in step S43, if the reference point is switched by clicking the reference point switching button 63a or 63b, then in step S44, the distance calculation unit 556 calculates the horizontal and vertical distances based on the new reference point and the position information of the measured device 40 obtained in the previous step S07. Next, in step S45, the measurement information display unit 557 displays an update.

[0132] Next, in step S46, it is determined again whether to continue the observation confirmation. If the observation confirmation is completed by pressing the observation and confirmation button 69 again, the process proceeds to step S10.

[0133] In this way, the reference point can be switched by the observation and confirmation button 69 while keeping the current position fixed, and distances can also be calculated for other reference points. Based on the above configuration, the horizontal and vertical distances to two or more constituent points can be calculated and confirmed for the same point.

[0134] (Modified Example)

[0135] As a variation of this embodiment, referred to as the "intermediate function," an example will be described whereby, in addition to serving as a reference point for measuring horizontal and vertical distances, the horizontal and vertical distances can also be measured from an inclined plane in the design information.

[0136] Figure 10 This is a block diagram of the configuration of a modified measurement auxiliary system 100a. In system 100a, the terminal control unit 55a of the measurement auxiliary device 50a replaces the distance calculation unit 556a, and a distance calculation unit 556a is provided.

[0137] In addition to the functions of the distance calculation unit 556, the distance calculation unit 556a also has the following function: when the route function is selected, instead of calculating the horizontal and vertical distances between the reference point and the position of the measured device 40, it calculates the horizontal and vertical distances of the current position of the measured device 40 relative to the plane (sloping or horizontal plane) on the design that includes the reference point.

[0138] Figure 11 (A)~ Figure 11 (F) represents the plane (sloping or horizontal) on which the horizontal and vertical distances are calculated when the measured device 40 is in various positions in the cross-sectional view (partial). In the figure, the solid line is a cross-section of the design information, 〇 represents the constitutive point, and the dashed line containing the measured device 40 represents the horizontal distance d9 and the vertical distance d9 calculated by this function. 10 .

[0139] Additionally, the functions can also be assigned to function icons 67a, 67b, 67c, ... (displayed on the observation screen 60). Figure 4 ) and execute.

[0140] Based on the above configuration, it is possible not only to determine the distance from the reference point, but also the horizontal and vertical distances from the current position to the slope. This allows for the calculation of the difference in distance relative to the slope, especially in situations where measurement is impossible due to obstacles or other factors at the desired point.

[0141] If configured as described above, in addition to the horizontal and vertical distances from the configuration point or center point, it is also possible to measure the horizontal and vertical distances from the position of the measured device 40 to the plane.
