Description

The present invention relates to a surveying apparatus, a surveying method, and a program .

  There are various techniques (for example, refer to Patent Document 1) for performing a marking operation (also referred to as an installation operation of a surveying point or a pile driving point) using a surveying device. Here, examples of the surveying apparatus include a theodolite that can measure only an angle, and a total station (TS) that can simultaneously measure a distance and an angle.

  FIG. 11 is a diagram illustrating an example of the marking operation performed using the conventional surveying apparatus 100. Here, the crosses in FIG. 11 indicate the inking position on the building floor where the inking operation is performed.

  As shown in FIG. 11, the operator collimates the target R, which is a survey target, with the surveying device 100 installed on the reference point, and measures the direction and distance of the target R. Here, a reflection prism (also referred to as a mirror) can be given as a target.

As a result, the distance between the target R and the marking position (also referred to as a survey point or stakeout point) P and the direction from the target R toward the marking position P are displayed on the display unit of the surveying apparatus 100. Then, based on the information displayed on the display unit of the surveying instrument 100 as described above, the worker moves the target R so as to match the marking position P.
Here, an example of the inking operation will be described with reference to FIG.

  If a worker who operates the surveying apparatus 100 and a worker who moves while holding the target R are performing the marking work, the worker who operates the surveying apparatus 100 is displayed on the display unit of the surveying apparatus 100. The operator having the target R is guided to the inking position P based on the information such as “to the right OOm” and “backward OOm” indicating the difference between the position of the target R and the inking position P. To do.

At this time, the value displayed on the display unit of the conventional surveying device 100 is displayed with reference to a coordinate system including a coordinate axis A connecting the surveying device 100 and the target R and a coordinate axis B orthogonal to the coordinate axis A. . In this example, a coordinate axis A connecting the surveying instrument 100 and the target R is a coordinate axis in the front-rear direction, and a coordinate axis B orthogonal to the coordinate axis A in the front-rear direction is a coordinate axis in the left-right direction. As described above, the value displayed on the display unit of the conventional surveying apparatus 100 is a value based on the positional relationship between the surveying apparatus 100 and the target R.
The worker who operates the surveying instrument guides the worker having the target R to the marking position P based on the information displayed on the display unit of the surveying instrument 100 in this way.
Further, in recent years, as a way of expressing the difference between the position of the target R and the inking position P, the angle formed by the position of the target R and the inking position P viewed from the surveying apparatus 100, and the position of the target R and the inking position are determined. Some of them represent the distance to the position P. Even in such a case, the worker who operates the surveying instrument 100 guides the worker having the target R to the marking position P based on the information on the angle and the distance.

JP 2002-202357 A

  However, an operator having the target R has to move to the marking position P only with information based on the positional relationship between the surveying instrument 100 and the target R without any indicators useful for movement around.

For this reason, the worker having the target R may move out of the correct moving direction, as indicated by the NG direction in FIG. In this case, time is spent on the ink marking work.
In addition, as described above, even when guidance is performed based on information on angles and distances that have been adopted in recent years, an operator having the target R moves out of the moving direction and spends time on the marking operation. May end up.

  Embodiments of the present invention will be described with reference to the drawings.

The surveying apparatus according to the present embodiment is, for example, a total station (hereinafter referred to as TS) in which a telescope is rotatable around two orthogonal axes. Here, examples of the TS include a manual TS (that is, MTS) that is manually operated, a motor-driven TS (that is, an STS) that automatically operates by motor driving, and the like. In addition, the motor-driven TS automatically tracks a moving target or an automatic collimating TS that has a function of automatically collimating a target (for example, a reflecting prism) that is a survey target in the field of view of the telescope. There is an automatic tracking TS having a function to perform. For example, in automatic tracking TS, surveying by one worker can be realized.
The surveying apparatus according to the present embodiment is configured as any one of the TSs as described above.
(Constitution)
FIG. 1 is a diagram illustrating a configuration example of an appearance of a surveying apparatus 1 according to the present embodiment.

  As shown in FIG. 1, the surveying device 1 is installed on a tripod (not shown) via a leveling device 2. The leveling device 2 is disposed between the base 3 (or the bottom plate) 3 mounted on the tripod, the mounting portion 4 to which the surveying device 1 is mounted, the base 3 and the mounting portion 4, and the mounting portion 4 with respect to the base 3. And a leveling screw 5 for adjusting the degree of inclination. For example, the operator adjusts the leveling screw 5 of the leveling device 2 before the start of the surveying work so that, for example, the bubbles in the bubble tube forming the inclination detecting unit provided in the attachment unit 4 are in a predetermined position. To do.

Further, the surveying instrument 1 has a main body 6 that is rotatable about the first axis O ₁ with respect to the mounting portion 4. The surveying device 1 is installed so that the posture is adjusted by the leveling device 2 and the first axis O ₁ is vertical.

In addition, the surveying instrument 1 has a telescope 7 that is rotatable with respect to the main body 6 around a _second axis O ₂ perpendicular to the _first axis O ₁ . Since the telescope 7 can rotate around the first axis O ₁ together with the main body 6, the telescope 7 can freely rotate around the orthogonal first axis O ₁ and second axis O _2. .
FIG. 2 is a block diagram illustrating an example of the internal configuration of the surveying apparatus 1.

As shown in FIG. 2, the surveying instrument 1 includes a distance measuring unit 11, a angle measuring unit 20, a horizontal rotation driving unit 12, a vertical rotation driving unit 13, a display unit 14, an information input unit 15, a drive command unit 16, and an input / output. An I / F 17, a storage unit 18, and a calculation unit 30 are included.
The distance measuring unit 11 includes the telescope 7 as a part of its configuration, and measures the distance to a surveying object such as a target.

  Here, generally, as a distance measuring method, there are a prism method using a reflector such as a reflecting prism and a non-prism method not using a reflecting prism. In the prism method, for example, the distance is measured from the time difference between irradiating the reflecting prism with laser light and receiving the reflected light. Here, as a thing provided with targets, such as a reflective prism, there exists a pole with a mirror, for example. Further, since the non-prism method does not use a reflecting prism and does not require a reflecting prism, the degree of freedom in surveying is higher than that of the prism method. That is, for example, in the non-prism method, it is possible to perform surveying from a remote place without entering the site. For example, in the present embodiment, the distance measuring unit 11 is configured using any of these distance measuring methods.

The angle measuring unit 20 includes a horizontal angle detecting unit 21 and an altitude angle detecting unit 22. The horizontal angle detection unit 21 detects a rotation angle (that is, a horizontal angle) of the main body 6 that rotates in the horizontal direction with respect to the base 4. The altitude angle detection unit 22 detects the rotation angle (that is, altitude angle) of the telescope 7 that rotates in the vertical direction (that is, vertical direction) with respect to the main body 6. For example, the horizontal angle detector 21 is a horizontal angle encoder, and the altitude angle detector 22 is an altitude angle encoder.
The horizontal rotation driving unit 12 performs driving for rotating the main body 6 in the horizontal direction. The vertical rotation driving unit 13 performs driving for rotating the telescope 7 in the vertical direction.

  The information input unit 15 is a part that is operated by a user to input information. For example, the information input unit 15 includes a push button switch such as a numeric keypad. The information input unit 15 outputs the input information to the calculation unit 30.

  The drive command unit 16 is provided with a drive command switch for commanding the rotation direction of each of horizontal rotation and vertical rotation. Then, the drive command unit 16 outputs a command signal corresponding to the pressed drive switch to the calculation unit 30.

  The input / output I / F 17 is an interface for performing data communication with an external device. Here, examples of the external device include a personal computer and a data collector (electronic field book).

  The storage unit 18 includes a ROM, a RAM, an HDD (Hard Disk Drive), and the like. The storage unit 18 stores various programs, fixed data, data acquired by the calculation unit 30 through processing, and the like. In the present embodiment, the storage unit 18 stores design coordinate data created by, for example, CAD.

  The calculation unit 30 performs various processes for the surveying apparatus 1. For example, the arithmetic unit 30 includes a microcomputer and its peripheral circuits. Specifically, as illustrated in FIG. 2, the calculation unit 30 includes a surveying control unit 31, a drive control unit 32, and an inking position setting processing unit 40.

  The surveying control unit 31 controls the distance measuring unit 11 and the angle measuring unit 20. Further, the surveying control unit 31 calculates a surveying value based on the detection values of the distance measuring unit 11 and the angle measuring unit 20. Then, the survey control unit 31 displays the calculated survey value on the display unit 14 such as a liquid crystal display. Here, the surveying control unit 31 can calculate the coordinate value of the collimated point (that is, the target) based on the distance, altitude angle, and horizontal angle that are the survey values. For example, the coordinate value is calculated as a coordinate value of a local coordinate system (relative coordinate system) set on the collimated surface.

A command signal from the drive command unit 16 is input to the drive control unit 32. And the drive control part 32 controls the drive which rotates the main body 6 and the telescope 7 by the horizontal rotation drive part 12 and the vertical rotation drive part 13 based on the command signal.
The inking position setting processing unit 40 performs a process of setting the inking position (also referred to as setting of a measuring point or a stakeout point).
FIG. 3 is a block diagram illustrating a configuration example of the inking position setting processing unit 40.

  As shown in FIG. 3, the marking position setting processing unit 40 includes a reference point coordinate value acquisition unit 41, a reference direction setting unit 42, a reference line setting data acquisition unit 43, a reference line setting unit 44, and a reference line coordinate system setting. A unit 45, an inking position coordinate value acquisition unit 46, a target coordinate value acquisition unit 47, a guidance value calculation unit 48, a display processing unit 49, and an inking completion determination unit 50.

  FIG. 4 is a flowchart showing an example of processing content realized by the configuration of the inking position setting processing unit 40 shown in FIG. Further, FIG. 5 is a diagram illustrating an example of a building floor where the surveying device 1 performs the marking operation. In the following, the processing content of each part in FIG. 3 will be described along the processing procedure in FIG.

As shown in FIG. 4, first, in step S <b> 1, the reference point coordinate value acquisition unit 41 acquires the coordinate value of the reference point for installing the instrument point. Specifically, the reference point coordinate value acquisition unit 41 determines the reference point based on the coordinate values of a plurality of known points (that is, points whose coordinate values are known) acquired by collimation by the surveying apparatus 1. Get the coordinate value. There are various methods for acquiring the coordinate value of the reference point based on the coordinate values of a plurality of known points. For example, in this embodiment, the coordinate value of the reference point is acquired based on the backward intersection method. In this case, the reference point coordinate value acquisition unit 41 acquires the coordinate value of the reference point (instrument point) based on the backward intersection method based on the coordinate values of a plurality of known points (columns, etc.) on the building floor shown in FIG. To do.
Next, in step S2, the reference direction setting unit 42 sets a reference direction by using the known point obtained by collimation as a rear viewpoint as a reference for the horizontal angle.

  Next, in step S3, the reference line setting data acquisition unit 43 acquires reference line setting data. Specifically, the reference line setting data acquisition unit 43 acquires reference line setting data according to the following procedure.

  FIG. 6 is a flowchart showing a specific example of the procedure for acquiring the reference line setting data in step S3. Note that the contents enclosed by the broken lines in FIG. 6 (the contents of steps S3-1, S3-2, and S3-5) are the work contents on the operator side, and the contents enclosed by the solid lines in FIG. 6 (step S3). -3, step S3-4, step S3-6, and step S3-7) are processing contents by the corresponding component of the inking position setting processing unit 40.

  First, an operator who operates the surveying apparatus 1 specifies a wall surface of a structure for setting a reference line (also referred to as a reference axis) (step S3-1). Specifically, the worker specifies the wall surface of the structure around the surveying apparatus 1 or the wall surface of the structure existing around the ink setting position.

  Thereafter, the operator who operates the surveying device 1 collimates with the surveying device 1 and instructs an arbitrary one point on the wall surface as a starting point (step S3-2). Thereby, the surveying control unit 31 measures the instructed start point and calculates the coordinate value (step S3-3). Then, the reference line setting data acquisition unit 43 acquires the calculated coordinate value of the starting point as starting point data for setting the reference line (step S3-4).

For example, the reference line setting data acquisition unit 43 collimates at the timing when an acquisition operation for acquiring the reference line setting data is performed on the surveying apparatus 1 (for example, the information input unit 15) by the operator. The starting point (that is, the coordinate value of the starting point calculated by the surveying control unit 31) is acquired as the starting point data for setting the reference line.
Then, the reference line setting data acquisition unit 43 stores (for example, temporarily stores) the acquired start point data in the storage unit 18.

  Furthermore, the reference line setting data acquisition unit 43 also acquires reference line setting end point data by the same procedure. That is, the operator operating the surveying instrument 1 collimates with the surveying instrument 1 and instructs another arbitrary point located laterally with respect to the start point on the same wall surface as the end point (step S3-5). As a result, the surveying control unit 31 measures the instructed end point and calculates the coordinate value (step S3-6). Then, the reference line setting data acquisition unit 43 acquires the calculated end point coordinate value as reference line setting end point data (step S3-7).

For example, the reference line setting data acquisition unit 43 collimates at the timing when an acquisition operation for acquiring the reference line setting data is performed on the surveying apparatus 1 (for example, the information input unit 15) by the operator. The coordinate value of the existing end point (that is, the end point coordinate value calculated by the surveying control unit 31) is acquired as the end point data for setting the reference line.
Then, the reference line setting data acquisition unit 43 stores (for example, temporarily stores) the acquired end point data in the storage unit 18.

  Here, the above procedure will be described with reference to FIG. 5. For example, the surveying device 1 collimates the planar wall surface 200 of the building floor specified by the operator and starts an arbitrary point on the surface 200 a of the wall surface 200. By instructing as S, the reference line setting data acquisition unit 43 side acquires reference line setting start point data (steps S3-1 to S3-4). Furthermore, when the operator collimates with the surveying apparatus 1 and designates another arbitrary point on the surface 200a of the wall surface 200a of the building floor as the end point E, the reference line setting data acquisition unit 43 side End point data is acquired (steps S3-5 to S3-7).

  The measurement of the start point and the end point may be performed by a prism method using a target such as a reflecting prism, but it is preferably performed by a non-prism method without using such a target. This is because the non-prism method can directly measure the wall surface and measure the start point and end point.

  Next, in step S <b> 4, the reference line setting unit 44 reads start point data (that is, the coordinate value of the start point) and end point data (that is, the coordinate value of the end point) from the storage unit 18. Then, the reference line setting unit 44 sets a line connecting the read start point data and end point data as a reference line.

  If it demonstrates using FIG. 5, the reference line setting part 44 will set the straight line which connects the start point S and the end point E on the wall surface of a building floor as a reference line (henceforth a structure top reference line). Then, the reference line setting unit 44 stores (for example, temporarily stores) information (for example, coordinate values) of the set reference line on the structure in the storage unit 18.

  Next, in step S <b> 5, the reference line coordinate system setting unit 45 reads information on the on-structure reference line from the storage unit 18. Then, the reference line coordinate system setting unit 45 has a coordinate axis parallel to the structural reference line (hereinafter referred to as a parallel coordinate axis) and a parallel coordinate axis in a plane (for example, a horizontal plane) including the read structural reference line. A two-dimensional coordinate system (hereinafter referred to as a reference line coordinate system) based on a reference line on the structure, which is composed of vertical coordinate axes (that is, a coordinate axis perpendicular to the reference line on the structure, hereinafter referred to as a vertical coordinate axis). ) Is set. Then, the reference line coordinate system setting unit 45 stores (for example, temporarily stores) information on the set reference line coordinate system in the storage unit 18.

  Next, in step S6, the inking position coordinate value acquisition unit 46 acquires the inking position coordinate value. For example, in the present embodiment, the marking position coordinate value acquisition unit 46 acquires the coordinate value of the marking position from the structure data stored in the storage unit 18, for example, CAD data. For example, the inking position coordinate value acquisition unit 46 acquires the position of the x mark shown in FIG. 5 on the CAD data as the inking position coordinate value.

  Here, the inking position coordinate value acquisition unit 46 may acquire the inking position coordinate value as a coordinate value in the existing coordinate system of the surveying apparatus 1 instead of the reference line coordinate system. You may acquire a coordinate value as a coordinate value in a reference line coordinate system.

  Next, in step S7, the target coordinate value acquisition unit 47 collimates the target and acquires the coordinate value calculated by the surveying control unit 31 as the target coordinate value. Then, the target coordinate value acquisition unit 47 stores (for example, temporarily stores) the acquired coordinate value of the target in the storage unit 18.

  Here, the target coordinate value acquisition unit 47 may acquire the target coordinate value as the coordinate value in the reference line coordinate system, and the target coordinate value is not the reference line coordinate system but the existing coordinates of the surveying apparatus 1. You may acquire as a coordinate value in a system.

  Next, in step S8, the induced value calculation unit 48 acquires the coordinate value of the inking position and the coordinate value of the target acquired in steps S6 and S7. Further, the induced value calculation unit 48 reads information on the reference line coordinate system from the storage unit 18. Then, based on the coordinate value of the inking position and the coordinate value of the target, the induced value calculation unit 48 and the distance from the target to the inking position (that is, the moving direction) and the distance between the target and the inking position ( That is, the movement distance) is acquired as the induced value of the reference line coordinate system. Then, the guidance value calculation unit 48 stores (for example, temporarily stores) the obtained guidance value (that is, the movement direction and the movement distance) in the storage unit 18.

  Hereinafter, the procedure for calculating the induced value by the induced value calculating unit 48 will be described in detail with reference to FIG. FIG. 7 is a diagram illustrating the moving direction and the moving distance that are the induced values calculated by the induced value calculating unit 48.

  First, as shown in FIG. 7, the induced value calculation unit 48 uses the direction from the target R toward the current inking position P as the value of the parallel coordinate axis indicating the positional relationship between the target R and the current inking position P. , The distance between the target R and the current inking position P is acquired. Here, the distance between the target R and the current marking position P is a distance in a direction parallel to the wall surface serving as a reference for setting the reference line on the structure. Further, as the direction from the target R to the current inking position P, the induced value calculation unit 48 sets, for example, the direction from the start point to the end point of the reference line on the structure as the “rear” direction, and the opposite direction. As the "front" direction.

  The direction acquired here is convenient information for the operator who operates the surveying instrument 1 to easily perform guidance, and for the operator having the target to easily understand the moving direction. Thus, it goes without saying that the direction from the start point to the end point is the “rear” direction and the opposite direction is the “front” direction.

  Next, as shown in FIG. 7, the guidance value calculation unit 48 uses the direction from the target R toward the current inking position P as the value of the vertical coordinate axis indicating the positional relationship between the target R and the current inking position P. And the distance between the target R and the current inking position P. Here, the distance between the target R and the current marking position P is a distance in a direction in which the target R is in contact with or separated from the wall surface that is the reference for setting the reference line on the structure. Further, as the direction from the target R to the current inking position P, the induced value calculation unit 48 sets, for example, the direction toward the reference line on the structure, that is, the direction toward the wall surface as the “left” direction, The opposite direction, that is, the direction away from the wall surface is acquired as the “right” direction.

  Note that the direction acquired here is convenient information for the operator who operates the surveying instrument 1 to easily perform guidance, and for the operator having the target to easily understand the moving direction. Thus, it goes without saying that the direction toward the wall surface is not limited to the “left” direction and the opposite direction is the “right” direction.

Returning to FIG. 4, next, in step S <b> 9, the display processing unit 49 reads the induced value from the storage unit 18 and displays the moving direction and moving distance on the display unit 14 based on the read induced value.
FIG. 8 is a diagram illustrating an example of a display mode of the moving direction and the moving distance on the display unit 14.

  As shown in FIG. 8, the display processing unit 49 displays “front” and “rear” on the display unit 14 as the movement direction display 14a, and displays the movement distance display 14b corresponding to the movement direction display 14a. 14 is displayed. The display processing unit 49 displays “left” and “right” on the display unit 14 as the movement direction display 14c, and displays a movement distance display 14d on the display unit 14 corresponding to the movement direction display 14c. For example, if the movement direction is “rear” and “left”, the display processing unit 49 highlights (for example, reverse display) “rear” and “left” of the movement direction displays 14a and 14c.

  Returning to FIG. 4, next, in step S <b> 10, the inking completion determination unit 50 determines whether or not the current inking has been completed. For example, the inking completion determination unit 50 determines whether an operation for determining the inking position has been performed on the information input unit 15 by the operator. If the inking completion determination unit 50 determines that the current inking has been completed, the process proceeds to step S11. If the inking completion determination unit 50 determines that the current inking has not been completed, the process starts again from step S7.

In step S11, the inking completion determination unit 50 determines whether there is a next inking position. That is, the inking completion determination unit 50 determines whether or not all inking for the current inking operation has been completed. For example, in this embodiment, the inking completion determination unit 50 acquires information on all inking positions for the current inking operation from CAD data, and whether or not all inking has been completed based on the information. Determine whether. If the inking completion determination unit 50 determines that there is a next inking position, the process starts again from step S6. If the inking completion determination unit 50 determines that there is no next inking position, the process shown in FIG. 4 ends.
(Inking procedure)

  Next, the procedure of the marking operation using the surveying apparatus 1 will be described with reference to FIGS. Here, FIG. 9 is a flowchart showing an example of the procedure of the inking operation. Here, the case where the marking operation is performed by a worker who operates the surveying apparatus 1 and a worker who has a target will be described.

First, the operator installs the surveying instrument 1 (instrument point) on the reference point and adjusts the surveying instrument 1 horizontally (step S31 in FIG. 9, step (1) shown in FIG. 5). At this time, as the surveying device 1 (instrument point) is installed on the reference point, the operator measures the surrounding known points with the surveying device 1 already installed horizontally, and the coordinate value of the reference point (instrument point). Is acquired (step S1).
Next, the operator determines the reference direction of the surveying instrument 1 and sets coordinates (step S32 in FIG. 9, step (2) shown in FIG. 5).
At this time, on the surveying instrument 1 side, the reference direction is determined based on the collimated viewpoint (step S2).

  Next, the operator determines a reference line on the structure before starting the guidance for setting the inking position (step S33 in FIG. 9, step (3) shown in FIG. 5). For this purpose, the worker specifies the wall surface of the structure for which a reference line on the structure is set, collimates with the surveying instrument 1, and instructs an arbitrary point on the wall surface as a starting point. Further, the operator collimates with the surveying instrument 1 and instructs another arbitrary point on the wall surface as the end point.

  As a result, the surveying apparatus 1 measures the instructed start point and end point to calculate coordinate values, and obtains the calculated coordinate values as start point data and end point data for setting a reference line (step S3). . Further, on the surveying instrument 1 side, a straight line connecting the acquired start point data and end point data is set as a structural reference line (step S4). Then, on the surveying instrument 1 side, a two-dimensional reference line coordinate system including parallel coordinate axes and vertical coordinate axes orthogonal to each other is set based on the set reference line on the structure (step S5).

  Next, the operator acquires the marking position on the surveying instrument 1 (step S34 in FIG. 9). For example, the operator operates the information input unit 15 of the surveying instrument 1 to read out the coordinate value of the inking position from CAD data or the like (Step S6).

Next, a moving direction and a moving distance, which are guide values for moving the target to the inking position, are displayed on the display unit 14 of the surveying instrument 1 (Step S35 in FIG. 9, Steps S7 to S9 in FIG. 9). ). That is, on the surveying instrument 1 side, when the target is collimated and its coordinate value is acquired, the target is moved to the inking position based on the coordinate value of the target and the previously acquired inking position coordinate value. The movement direction and the movement distance are calculated, and the calculated movement direction and movement distance are displayed on the display unit 14.
FIG. 10 is a diagram showing an example of a display mode of the display unit 14 when the error between the target R and the current marking position P is as shown in FIG.

  As shown in FIG. 10, in order to move the target in the backward direction, the surveying instrument 1 highlights (for example, reverse display) the “rear” in the movement direction display 14a and also displays, for example, “ 2.000m "is displayed. Further, the surveying instrument 1 highlights (for example, reverse display) “left” in the movement direction display 14c in order to move the target in the left direction, and sets “1.000 m” as the movement distance display 14d, for example. indicate.

  Next, the worker moves the target based on the moving direction and the moving distance displayed on the display unit 14 of the surveying instrument 1 (step S36 in FIG. 9, step (4) shown in FIG. 5). That is, the operator who operates the surveying instrument 1 works with the target so that the moving direction and the moving distance are the same, that is, the difference between the coordinate value of the target R and the coordinate value of the inking position P is zero. An instruction is given to the person and guided to the marking position P. For example, in the case of the display as shown in FIG. 10, the operator operating the surveying instrument 1 gives instructions as follows: “Move backward 2 m along the wall and move 1 m left toward the wall. To the worker who has the target.

  Next, the operator determines whether or not the current inking has been completed (step S37 in FIG. 9). If the current marking is not completed, the worker continues to move the target based on the moving direction and moving distance displayed on the display unit 14 of the surveying instrument 1 (steps S35 and S36). . That is, the worker who operates the surveying instrument 1 continues to guide the worker having the target.

  When the current inking is completed, the operator determines whether or not there is a next inking position (step S38 in FIG. 9). For example, the operator operates the information input unit 15 of the surveying apparatus 1 and confirms whether there is another marking position from CAD data or the like. Then, if there is a next inking position, the worker acquires the coordinate value of the next inking position and performs the inking operation for the next inking position (steps S34 to S37). . Further, if there is no next inking position, the worker ends the inking operation.

  As described above, in the present embodiment, the reference line on the structure is set on the wall surface of the structure in the inking work environment, and the remaining from the target to the inking position is determined in the reference line coordinate system based on the reference line on the structure. The difference distance is displayed on the display unit 14 of the surveying instrument 1 in the front-rear direction and the left-right direction. Then, the operator who operates the surveying instrument 1 guides the worker having the target to the inking position based on the information displayed on the display unit 14 of the surveying instrument 1 as described above. Thereby, the worker having the target can move the target to the inking position according to the guidance contents by the operator who operates the surveying apparatus 1 with reference to the wall surface of the visible structure in the inking operation environment. As a result, in the present embodiment, it is possible to prevent the movement from deviating from the correct movement direction toward the inking position during the inking operation.

  In particular, in the inking work such as the hanger position at the construction site, the interval between the current inking position and the next inking position is often less than 1 m. Furthermore, as shown in FIG. It is often designed so that the ink marking positions are arranged in parallel on the wall of the work environment. Because of this situation, an operator having a target can move the target with high accuracy from the current inking position to the next inking position even in visual measurement. As described above, in this embodiment, the operator's eye measurement is very effective, and the efficiency of the marking operation can be greatly improved.

  In many cases, there are joints, grooves and the like on the floor of the building. In many cases, the seam or the like extends parallel to the wall surface. In such a case, the operator can move the target to the inking position with reference to such a joint. Thereby, in the present embodiment, the efficiency of the inking operation can be greatly improved.

  Note that when the surveying instrument 1 is guided as in the prior art, the setting of the inking position is limited to about one point per minute. Further, in the setting of the marking position using general GPS, guidance is performed based on the residual numerical value based on the azimuth, and this is also limited to about one point per minute. Therefore, the setting of the conventional inking position does not change the productivity at all as compared with the conventional method using the inking line and the tape.

  On the other hand, in the present embodiment, by using the wall surface of the inking operation environment as described above, the inking operation efficiency is improved, and productivity can be increased as compared with the conventional inking operation.

In the description of the above-described embodiment, the distance measuring unit 11 and the angle measuring unit 20 constitute, for example, a measuring unit. Further, the reference line setting data acquisition unit 43 (or the surveying control unit 31 and the reference line setting data acquisition unit 43) realizes, for example, an instruction value acquisition unit. Further, the surveying control unit 31 and the target coordinate value acquisition unit 47 realize, for example, a survey target body coordinate value acquisition unit. Moreover, the induced value calculation part 48 implement | achieves an induced value acquisition part, for example. Moreover, the information input part 15 comprises an input part, for example.

In the present embodiment, the coordinate values of the start point and the end point of the reference line on the structure are created by data stored in the storage unit 18 by the surveying device 1 without being actually measured by the surveying device 1, such as CAD. It can be obtained using design coordinate data. In this case, the operator operates the information input unit 15 on the surveying instrument 1 and instructs the start point and the end point on the wall surface of the structure of the design coordinate data. As a result, the reference line setting data acquisition unit 43 acquires coordinate values for the specified start point and end point.
In the present embodiment, the instructed line segment can be set as a reference line. In this case, for example, the operator operates the information input unit 15 on the surveying instrument 1 to instruct a line segment on the structure in the design coordinate data created by CAD or the like.

  In such a configuration, when the information input unit 15 serving as the selection unit is operated by the operator and the reference line correspondence calculation mode is selected, the surveying apparatus 1 calculates the induced value using the reference line coordinate system. To do. In addition, when the information input unit 15 is operated by the operator and the instrument point correspondence calculation mode is selected, the surveying apparatus 1 calculates the induced value using the instrument point reference coordinate system.

In this case, in this embodiment, the reference line on the structure is appropriately set according to the floor surface shape. For example, in this embodiment, after setting the reference line on the structure on one wall surface of a building floor having an L-shaped floor and completing the inking operation, another wall surface adjacent to the one wall surface (that is, Next, the reference line on the structure is re-set on the wall that intersects the one wall surface at a right angle, and the next inking operation is performed. As a result, the surveying apparatus 1 can display an induced value adapted to such a building floor even when performing inking on a building floor having a bent floor surface such as a character or L-shape. it can.

  Further, the present embodiment can be applied not only indoors but also to work sites such as outdoor ink marking work and standard roads. Even in this case, in the present embodiment, it is possible to efficiently perform the marking operation.

  Moreover, in this embodiment, it can apply also when the wall surface and the road are curving. In this case, in the present embodiment, the position of three arbitrary points on the wall surface or the road (the center of the road or the roadside belt) is acquired, and the radius etc. is calculated based on each acquired position. A curve along the curved surface is set as a reference line on the structure. Thereby, in this embodiment, it is possible to perform the inking operation on the basis of the curved portion of the structure.

  In the present embodiment, the reference line can be set not only on the wall surface but also on the floor surface or the ground. In this case, the operator who operates the surveying device 1 instructs the start point and the end point of the floor, the ground, etc., so that the worker with the target can use it as a reference when moving, and the surveying device 1 A reference line is set based on the specified start point and end point.
