Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in actual construction sites, many workers who perform operations such as "placement" are not skilled in handling computers and the like. Therefore, they cannot use the design drawing information created by CAD on their own portable terminals, and as a result, there is a problem that the design drawing information of CAD cannot be effectively utilized at construction sites and the like.

[0019] Hereinafter, preferred embodiments of this invention will be described in detail with reference to the accompanying drawings and other materials. The embodiments described below are preferred examples of the present invention and are subject to various technically preferred limitations. However, the scope of the present invention is not limited to these embodiments unless otherwise stated in the following description.

[0020] (Main components of Surveying Support System 1) Figure 1 is a schematic diagram showing the main components of Survey Support System 1, which is an example of the Survey Support System of the present invention. As shown in Figure 1, System 1 includes a portable terminal 200, which is an example of a surveying support device operated by operator U, who is a surveying worker for System 1; a management server 300, which is an example of a design information management device that stores design information including building layout information, which is an example of a construction target, site boundary information, which is an example of site information on which a building is located, and design CAD drawing information, which is an example of basic design information. This design CAD drawing information is, for example, created and stored using CAD software. Furthermore, as shown in Figure 1, this system 1 has a surveying pole 500 held by operator U, and this surveying pole 500 is equipped with a reflective prism 501 used during surveying.

[0021] Furthermore, System 1 includes surveying equipment 100 such as a total station for measuring site boundaries and layout information. This surveying device 100 is a combination of an optical distance meter for measuring distance and a theodolite for measuring angle. It is configured to easily determine the position of a new point from the distance obtained by receiving reflected light from an object to be measured, such as a reflecting prism 501, and the angle in the direction of the telescope tube 8 (Figure 2). The specific configuration will be described later.

[0022] Furthermore, as shown in Figure 1, the management server 300 and the mobile terminal 200 are configured to communicate with each other via the internet network 410 and base station 412, etc., and the mobile terminal 200 and the surveying device 100 are also configured to communicate with each other.

[0023] The management server 300, mobile terminal 200, and surveying device 100 in Figure 1 each have a computer, which includes a CPU (Central Processing Unit), RAM (Random Access Memory), ROM (Read Only Memory), etc. (not shown), and these are connected via a bus or the like.

[0024] (Main components of the surveying device 100) Figure 2 is a schematic diagram illustrating the main internal components of the surveying device 100 shown in Figure 1. As shown in Figure 1, the surveying device 100 is positioned on a tripod base 101. This surveying device 100 has a surveying instrument body 5 consisting of a base 3 and a rotating base 4 that rotates horizontally relative to the base 3, and a cover member 6.

[0025] The base unit 3 comprises a fixing base 3a that is fixed to the tripod base 101, a leveling base 3b having a leveling screw, and a case unit 3c that houses a drive mechanism such as a horizontal drive motor that rotates the rotating base 4 in the horizontal direction.

[0026] As shown in Figure 2, a support member 7 is erected on the rotating base 4. As shown in Figure 2, horizontal axes 8A, 8A are provided on this support member 7 to support the lens barrels 8 of the distance measuring optical system and the tracking optical system so that they can rotate vertically.

[0027] A vertical drive motor M2, which rotates the lens barrel 8 in the vertical direction, is fixed to one end of the horizontal axis 8A, and an encoder 10 for detecting the rotation angle of the lens barrel 8 is provided at the other end of the horizontal axis.

[0028] A control circuit board 11 that controls the horizontal rotation of the rotating base 4 and the vertical rotation of the lens barrel 8, and a guide light irradiation unit 12 are fixed to the upper end of the support member 7. The horizontal drive motor, vertical drive motor M2, encoder 10, etc. are connected by a flexible printed circuit board.

[0029] The control circuit board 11 is equipped with a CPU, and the guide light irradiation unit 12 in Figure 2 is used to indicate the sighting direction of the surveying instrument body 5 to the operator U.

[0030] As shown in Figure 2, the cover member 6 has a fitting opening 6a that fits onto the outer circumference 4a of the rotating base 4, a covering portion 6b that covers the guide light irradiation portion 12, a handle portion 6c, and a window portion 6d that extends in the vertical direction. Furthermore, a sealing member is provided on the outer circumference 4a of the rotating base 4 to prevent rainwater and other substances from entering.

[0031] The lens barrel section 8 is equipped with a rangefinder optical system and a tracking optical system. The inclination of the optical system in the lens barrel 8 is determined by measuring the angle using the encoder 10. The "guide light irradiation unit 12" of the surveying device 100 performs the function of indicating the sighting direction of the surveying device 100, and the "surveying optical system" of the same device 100 performs the function of calculating the distance to the measurement point (reflecting prism 501, etc.). Furthermore, the "tracking optical system" of the device 100 exhibits the function of automatically tracking target objects such as the reflective prism 501.

[0032] In this embodiment, a surveying device 100 that uses a "reflecting prism 501" for measurement is described as an example, but the present invention is not limited to this and also includes surveying devices that do not use a reflecting prism 501 for measurement. When performing measurements using the reflective prism 501, operator U in Figure 1 carries the surveying pole 500 equipped with the reflective prism 501 and moves to the measurement point. Then, a surveying pole 500 is set up at the measurement point, and the tracking light and distance measuring light emitted by the surveying device 100 are reflected by the reflecting prism 501. The surveying device 100 receives the reflected light from the reflecting prism 501 to obtain the position of the reflecting prism 501, and uses this to guide and measure the reflecting prism 501 (operator U holding the surveying pole 500).

[0033] (Main configuration of management server 300, etc.) Figure 3 is a schematic block diagram showing the main configuration of the management server 300 shown in Figure 1. As shown in Figure 3, the management server 300 has a "server-side control unit 301," which controls a "server-side communication device 302" that communicates with the mobile terminal 200 shown in Figure 1, a "server-side display 303" that displays various information, and a "server-side various information input device 304" that inputs various information. Furthermore, as shown in Figure 1, the control unit 301 also controls the "server-side design CAD drawing information storage unit 305" and the "server-side various information storage unit 306," which store "design CAD drawing information" and the like created with CAD.

[0034] (Main components of the mobile terminal 200, etc.) Figure 4 is a schematic block diagram showing the main components of the mobile terminal 200 shown in Figure 1. As shown in Figure 4, the mobile terminal 200 has a "terminal-side control unit 201," which controls the "terminal-side communication device 202" and "touch panel 203" that communicate with the management server 300 and surveying equipment 100 shown in Figure 1.

[0035] This touch panel 203 is a "touch panel type display," and a touch panel is an electronic component that combines a display unit and a position input device. It is an input device that allows the operator U to input various information by touching the display on the display. Furthermore, as described above, the touch panel 203 has two functions: display and input. It displays image information received from an external source such as a computer on an LCD display, and when the operator U touches a point or area of ​​a picture or pictogram displayed on the screen with their hand and applies pressure, it senses the position of the touched screen and outputs the information as an information signal to the outside.

[0036] Furthermore, there are several types of touch panels 203, and in this embodiment, for example, a "capacitive touch panel" is adopted. The capacitive touchscreen method uses a sensor to detect the weak electric current generated when a finger touches the screen, i.e., the change in capacitance (charge), and to determine the location of the touch by the user U. Furthermore, the sensor reacts to the capacitance of the human body when a finger is brought close to the screen.

[0037] Figure 5 is a schematic diagram illustrating the main configuration of images and other elements displayed on the touch panel 203 according to this embodiment. As shown in Figure 5, a "coordinate layer 240" is placed on the touch panel 203 side, and an "image layer 241" is placed below it (on the back side of the coordinate layer 240). Furthermore, the operator U of the touch panel 203 can view the "design PDF drawing information" displayed in the "image layer 241" on the touch panel 203, and can also grasp the "lines" and "points" of the "design PDF drawing information" as XY axis coordinate information.

[0038] Furthermore, the control unit 201 in Figure 4 controls the "portable design CAD drawing storage unit 204" which stores the "design CAD drawing information" described later, and also controls the "intermediate converter software related information storage unit 210" which stores information related to the "intermediate converter software," which is an example of a "control program for the surveying support device." Furthermore, the control unit 201 also controls the "survey support software storage unit 205," which stores "survey support software," an example of a survey support unit.

[0039] Figure 6 is a schematic block diagram showing the main configuration of the intermediate converter software-related information storage unit 210 shown in Figure 5. These configurations will be described later.

[0040] (Examples of main operations of Survey Support System 1) Figures 7 and 8 are schematic flowcharts showing the main operation examples of the surveying support system 1 according to this embodiment. In this embodiment, the following explanation will be based on the example of a case where workers working on a site use the surveying device 100 shown in Figure 1 to perform tasks such as "layout" of a building when constructing a building on the site.

[0041] First, proceed to step 1 of Figure 7 (hereinafter referred to as "ST"). In ST1, the mobile terminal 200 shown in Figure 1, operated by the worker, obtains the "design CAD drawings" of the building to be constructed on the site from the management server 300 and stores them in the "mobile-side design CAD drawing storage unit 204" shown in Figure 4.

[0042] Next, the process proceeds to ST2. In ST2, the "format change unit (program) 211" shown in Figure 6, which is an example of the "image information conversion unit" of the mobile terminal 200, operates to change the "design CAD drawing" to a "design PDF drawing" in PDF (Portable Document Format) format, which is an example of "image design information," and stores it in the "design PDF data storage unit 212" shown in Figure 6. In addition, unlike this embodiment, the present invention may also be configured to directly store the design drawings provided in PDF format in the "design PDF data storage unit 212" without operating the "format change unit (program) 211".

[0043] Next, proceed to ST3. In ST3, "scale adjustment" is performed. In this step, at least two points on the "design PDF drawing" are measured on the site using the surveying device 100. This adjusts the orientation and scale of the design PDF drawings. For example, the surveying device 100 measures a point on the site and obtains its coordinates while tracking the reflective prism 501. By performing this process for two points, the orientation and scale of the design PDF drawing are determined. Specifically, the "scale change unit (program) 213" in Figure 6 of the mobile terminal 200 operates, changing the length between two points on the "design PDF drawing" from a scale of "1 / 250" using the measured length, and storing it in the "scale-changed design drawing storage unit 214" in Figure 6.

[0044] Next, the process proceeds to ST4. In ST4, "coordinate extraction" is performed. Specifically, the "coordinate extraction unit (program) 220," which is an example of a "coordinate information generation unit," operates and automatically determines the orientation of the "design PDF drawing" at the site based on the measurement of two points by ST3, and stores the coordinates of the "points" (an example of coordinate information) in the "design PDF drawing" displayed on the touch panel 203 in the "direction information storage unit 221" in Figure 6. Here, the coordinates of the "points" are stored in the "coordinate storage unit" in association with the design PDF drawing and the coordinate information acquired by the surveying device 100 at the time of surveying. Therefore, the "coordinate extraction unit 220" is configured to provide coordinate values ​​to the design PDF drawing information based on the coordinate information of the coordinate storage unit.

[0045] Figure 9 is a schematic diagram illustrating the point information of the layout. As shown in Figure 9, for example, by defining the coordinates of a point (k001) of the layout information (information such as the foundation part where the building will be constructed), the orientation of the "design PDF drawing" at the site is automatically determined, and that orientation is stored in the "direction information storage unit 221" in Figure 6.

[0046] In this embodiment, point and line information is automatically generated from the design PDF drawing information, so even if the operator U is unfamiliar with coordinate extraction, they can easily extract the coordinate information of points on the "design PDF drawing".

[0047] In addition to the automatically extracted "points," the operator U can also input the coordinates of a new "point" using the touch panel 203. In this case, the point can be stored as a "new point" in the "new point storage unit 222" shown in Figure 6. Figure 10 is a schematic diagram illustrating a "new point." As shown in Figure 10, in this embodiment, in addition to the point information (k001 to k004) of the automatically extracted placement information, "new points (N001 to N004)" are identified and stored.

[0048] Unlike this embodiment, in this invention, the coordinates of "points" on the XY axes of the "design PDF drawing" are not automatically extracted. Instead, the operator U may extract (identify) any point as a "point" and store its coordinates.

[0049] With the above steps completed, the process of extracting coordinate points before the actual survey is finished. Subsequently, the "Survey Support Software" in the "Survey Support Software Storage Unit 205" shown in Figure 4 will start operating, and the survey on the site will begin.

[0050] Next, proceed to ST5. In ST5, the surveying process using the surveying device 100 is performed. First, by communicating with the surveying device 100, the mobile terminal 200 displays a guidance screen on the touch panel 203 for the selected coordinate points (an example of selected coordinate information, such as k001 to k004 in Figure 10) of the design value (design point) (an example of design value information) selected by the operator. Operator U is guided by this guidance screen and places the "reflecting prism 501" at the indicated location to survey the location corresponding to the design point. The actual measured value (an example of actual measured value information) of the actual measured point (an example of a surveyed location) corresponding to the design point is stored in the "actual measured value information storage unit 223" in Figure 6.

[0051] As described above, this embodiment includes a "format conversion unit 211" that converts "design CAD drawing information" acquired from the management server 300 into "design PDF information" for display on the touch panel 203. Therefore, even an operator U who is unfamiliar with handling CAD data can easily and quickly import CAD data into a usable format on the mobile terminal 200.

[0052] Furthermore, this embodiment includes a "coordinate extraction unit 220" for identifying the layout information, boundary information, etc., of the design information using coordinate information, so that the imported CAD data, etc., can be automatically displayed as coordinate information on the touch panel 203. Furthermore, according to this embodiment, since the system has surveying support software that displays a guidance screen on the touch panel 203 to guide the operator U to the survey point (actual measurement point, etc.) of the selected coordinate information, the operator U can be easily and quickly guided to the target survey point and allowed to perform the survey based on design drawings such as CAD data.

[0053] Thus, according to this embodiment, even operators U at construction sites who are unfamiliar with handling CAD data can easily and quickly utilize CAD data.

[0054] Next, the process proceeds to ST6. In ST6, the "Difference Information Generation Unit (Program) 224" shown in Figure 6 operates, comparing the design value at the design point with the measured value at the corresponding measured point, and storing the difference data in the "Difference Information Storage Unit 225" shown in Figure 6. For example, if point k002 in Figure 10 differs by 15 mm in the X direction (horizontal direction in Figure 10) and by 10 mm in the Y direction (vertical direction in Figure 10), the difference data is stored in the "difference information storage unit 225".

[0055] Furthermore, this difference information is displayed as a "difference list" on the touch panel 203 screen. Figure 11 shows an example screen displaying the "difference list" on the touch panel 203. As shown in Figure 11, it can be seen that the measured point "L002" is 15 mm away from the design point "k002" in the X direction and 10 mm away in the Y direction.

[0056] Next, proceed to ST9. In ST9, based on the difference information in the "difference information storage unit 225" in Figure 6, the design drawing reflecting the measured points is displayed on the touch panel 203. Specifically, first, the "Revised Design Information Generation Unit (Program) 226" in Figure 6 operates to identify the coordinates of the measured points corresponding to the measured values. If the measured points and the design points differ, the measured points are designated as revised design points, and a new line is automatically created between these points and other design points, generating revised design information which is then stored in the "Revised Design Information Storage Unit 227" in Figure 6.

[0057] The design drawing information based on this "revised design information" is displayed on the touch panel 203. Figure 12 shows an example of a screen displaying design drawing information that reflects the revised design information. In Figure 12, the layout information reflecting the revised design information is displayed, and the design point (k002) has been changed to the measured point (L002).

[0058] As described above, according to this embodiment, if there is a discrepancy between the design values ​​and the measured values ​​in the design PDF drawing information, the design information is corrected to reflect the measured values ​​and displayed on the display unit, allowing the operator U to immediately grasp the corrected design information based on the measured values.

[0059] Next, proceed to ST8. In ST8, it is determined whether or not a "new point" has been designated by the operator. If ST9 determines that mobile device 200 has specified a "new point," proceed to ST9. In ST9, the surveying support software guides the operator to the new point, and when the operator places the "reflecting prism 501" at that location, the surveying device 100 performs the survey and stores the new point measurement point corresponding to the new point in the "new point measurement point storage unit 228" in Figure 6.

[0060] Then, the design PDF drawing information, including the newly measured points, is displayed on the touch panel 203. Figure 13 shows an example screen displaying both revised design information and new actual measurement point information. As shown in Figure 13, the system 1 is easy for operator U to understand because it also shows newly measured points.

[0061] Next, proceed to ST10. If ST8 determines that mobile terminal 200 has not specified a "new point," proceed to ST10. In ST10, the modified "design PDF information (image layer 241)" is registered (stored). In other words, prior to this step, the data of the measured values ​​in the "coordinate layer 240" was modified and stored in the "modified design information storage unit 227" in Figure 6, but the changes to the "design PDF drawing information" itself were not registered. Therefore, in this step, the changes to the "design PDF drawing information" itself are registered.

[0062] Specifically, the "Image Information Correction Unit (Program) 229" in Figure 6 operates, and based on the corrected design information and new point measurement information (if registered), it modifies the design PDF drawing data to generate "Corrected Design PDF Drawing Information," which is then stored in the "Corrected Design PDF Drawing Information Storage Unit 230" in Figure 6.

[0063] Next, proceed to ST11. In ST11, modify the CAD data on the mobile terminal 200. Specifically, the "Design CAD Drawing Modification Unit (Program) 231" in Figure 6 operates, and based on the "Modified Design PDF Drawing Information" in the "Modified Design PDF Drawing Information Storage Unit 230" in Figure 6, it modifies the "Design CAD Drawing" in the "Mobile-Side Design CAD Drawing Storage Unit 204" in Figure 4 to create a "Modified Design CAD Drawing," which is then stored in the "Mobile-Side Design CAD Drawing Storage Unit 204" in Figure 4.

[0064] Next, proceed to ST12. In ST12, modify the CAD data on the management server 300. Specifically, the mobile terminal 200 sends the "revised design CAD drawing" from the "mobile-side design CAD drawing storage unit 204" in Figure 4 to the management server 300. The management server 300 stores the received "revised design CAD drawings" in the "server-side design CAD drawing information storage unit 305" shown in Figure 3.

[0065] As described above, according to this embodiment, the "design CAD information" in the mobile terminal 200 and the management server is automatically modified based on the "modified design PDF information" acquired by the mobile terminal 200. Therefore, even an operator U who is not proficient in handling CAD data can easily and quickly modify the CAD data.

[0066] Furthermore, this embodiment includes a "revised design PDF drawing information storage unit 230" that stores "revised design PDF drawing information," which is the revision information of the "image layer 241," and a "revised design information storage unit 227" that stores "revised design information" based on the measured values ​​(measured value information) of the measured points (survey locations) in the "coordinate layer 240," and these pieces of information are stored separately. Therefore, even when there is a request to change the measured values ​​in "Coordinate Layer 240" and the design values ​​in "Image Layer 241" (which do not contain measured values) due to the needs of the work, such as when workers change from day to day at a construction site or when the work content of the workers changes, the system can accommodate such requests and is easy to use.

[0067] (Other features of the Touch Panel 203) As described above, the "design PDF drawing information" displayed on the touch panel 203 in this embodiment is configured to allow the drawing information to be transformed, moved, zoomed, etc., on the screen of the touch panel 203, based on the functions of the touch panel 203 described above. Specifically, the touch panel 203 combines an "image layer 241" and a "coordinate layer 240," with the "design PDF drawing information" being represented by the "image layer 241," and the "coordinate layer 240" understanding the coordinate information of this design PDF drawing. Therefore, the position of the design PDF drawing information is determined from the coordinate information obtained when operator U touches the screen of the touch panel 203, and the drawing is moved, deformed, zoomed, etc., by computer control.

[0068] Furthermore, the touch panel 203 according to this embodiment is configured to perform the following functions. Specifically, these include "display of the installation location of the surveying device 100," "import of design PDF drawings," "alignment of design PDF drawing information on the touch panel 203," "display on the touch panel when guiding to the survey point with the surveying support software," "enlargement of the design PDF drawing on the touch panel 203 and display of its precise position," and "the ability to change the reference point as needed."

[0069] The following describes each function. (Indication of the installation location of the surveying device 100) Figure 14 is a schematic diagram illustrating the display at the installation location of the surveying device 100 in the touch panel 203 according to this embodiment. As shown in Figure 14, first, operator U sets an arbitrary point on the touch panel 203 screen, for example, the position of the markings on the site (the reference point on the site), as the "origin 400," and based on this origin, sets an example of reference axis information, the "reference axis 401," in the vertical direction.

[0070] Then, when operator U clicks the "equipment installation icon 402," which is the "equipment installation" icon displayed on the touch panel 203, the "reference axis distance estimation unit (program) 233" in Figure 6 of the mobile terminal 200 is activated. Based on the design PDF drawing and the coordinate information of the reference axis 401, it determines the "length" of the reference axis, for example, 10m, and displays it on the touch panel 203. Furthermore, the "Survey Installation Position Calculation Unit 234" shown in Figure 6, which calculates the installation position of the "Surveying Device 100," operates, converts the installation position of the "Surveying Device 100" into "Coordinate Information (X-axis, Y-axis)," stores it, and displays it on the touch panel 203 using its coordinates, as shown in Figure 14.

[0071] Therefore, operator U can easily and accurately determine the placement of the surveying device 100 based on the markings and other reference points at the site.

[0072] (Import design PDF drawings) Figure 15 is a schematic diagram illustrating the state of "importing design PDF drawing information 500 into the touch panel 203" according to this embodiment. As shown in Figure 15, when the operator clicks the "Import Drawing Icon 403" displayed on the touch panel 203 and imports the design PDF drawing information 500 to the mobile terminal 200, the "design PDF drawing information 500" can be imported into the "image layer 241" in Figure 5, and the "design PDF drawing information 500" can be displayed on the touch panel 203 in a simple and quick manner.

[0073] Thus, in this embodiment, even if the design drawing information is not in CAD format but in PDF or the like, it can be easily and quickly displayed on the touch panel 203, resulting in a user-friendly configuration for the operator U.

[0074] (Alignment of design PDF drawing information on touch panel 203) Figure 16 is a schematic diagram illustrating the "drawing alignment of design PDF drawing information 500 in the touch panel 203" according to this embodiment. As shown in Figure 16, when the operator U clicks the "drawing alignment icon 404" displayed on the touch panel 203 and aligns the "line (a line extending vertically along the boundary line)" of the "design PDF drawing information 500" displayed on the touch panel 203 with the already set "reference axis 401", the operator U can adjust the "direction and dimensions" by touching the touch panel 203 and rotating, moving, and zooming the drawing with their finger.

[0075] As described above, according to this embodiment, the design PDF drawing information 500 can be freely moved, rotated, zoomed, etc. using the touch panel 203, thereby allowing any line in the design PDF drawing information 500, such as one side of the site boundary line, to be aligned with a predetermined arbitrary origin 400 and a reference axis 401 including this origin.

[0076] Therefore, without requiring the operator U to be aware of coordinate processing in the drawing, the display of the design PDF drawing information 500 can be changed simply by freely changing the display on the touch panel 203, and surveying can be performed based on the design PDF drawing information 500. Furthermore, since it can be operated even if the imported drawing information is in the form of a design PDF drawing (500 files), it is easy to use even for users who do not have CAD software.

[0077] (Display on the touch panel 203 when guiding to a survey point using survey support software) Figure 17 is a schematic diagram illustrating the display on the touch panel 203 when guiding the user to a survey point using survey support software. As shown in Figure 17, the intersection of the "parent ink" vertical axis 600 and the parent ink horizontal axis 601 displayed on the touch panel 203 is defined as measurement point A 700 (reference point) (X1, Y1, Z1), and the intersection of the "child ink" vertical axis 600a and the child ink horizontal axis 601a is defined as measurement point B 700a (separation).

[0078] Here, "main ink" refers to the ink marking the "centerlines," which are imaginary lines shown in the design drawings, and is the basic ink marking used in the marking process. Furthermore, "child ink" refers to ink produced using the parent ink as a reference.

[0079] In Figure 17, when operator U specifies the measurement of measurement point A, clicking the "Measurement Point A (X1, Y1, Z1) icon 603" on the touch panel 203 screen displays a screen guiding to measurement point A 700. On the other hand, clicking on the "Measurement Point B (X2, Y2, Z2) icon 603a" will display a guide map to Measurement Point B 700a.

[0080] Furthermore, on the guidance screen for surveying measurement point B 700a (detached), which is the measurement point of the sub-marker, the distance to the main marker (D1, D2) is displayed, as shown in Figure 17. Therefore, operator U can perform the survey while keeping track of the distance between measurement point A 700 (reference point) and measurement point B 700a (distance), and can easily align the measurements.

[0081] (Enlarging the design PDF drawing on touch panel 203 and precisely positioning the drawing) Figure 18 is a schematic diagram illustrating the "enlargement of design PDF drawings on touch panel 203 and the precise display of their position." As shown in Figure 18, the "Design PDF Drawing Information 500" section displayed on the touch panel 203 can be enlarged, and the "Center Line C," which is a guideline for construction, can also be displayed at the same time. Furthermore, in this embodiment, the position of the reference point (measurement point A in Figure 17) displayed on the touch panel 203 can be freely changed to any desired position.
