Therefore, in order to position and adjust the building structural material 11 to the design position, the design position of the marker 12 can be calculated based on the design position of the member core, and the actual position of the marker 12 is the design position of the marker 12. It is also possible to operate the building adjustment jig 13 so as to approach. In that sense, the meaning of "colliming the design position of the member core" is to collimate the position where the marker 12 attached to the building structural material exists, assuming that the member core exists at the design position. Alternatively, it has been described above that the position of the member core having the same height as the mounting height of the marker 12 is collimated.

In the slanted lumber 11 of FIG. 7 (b), the slanted lumber 11 of FIG. 7 (c), and the wall material 11 of FIG. 7 (d), the positional relationship between the marker 12 and the member core P is determined in advance by an offset value in the same manner as described above. ing.

As shown in FIG. 8B, in the pillar 11 whose building structural material is circular in a plan view, the positional relationship between the marker 12 and the member core P cannot be specified by an offset value. Therefore, the surveying instrument 10 is used to acquire the prism survey data for the marker 12, and the non-prism survey data is acquired for the position Q separated from the marker 12 along the peripheral surface at the same height as the marker 12. Calculate the position of the member core P with.

The intersection of the radius circle of the pillar 11 centered on the position of the marker 12 and the radius circle of the pillar 11 centered on the position Q can be calculated as the position of the member core P.

Further, the angle θ between the collimation line from the surveying instrument 10 to the marker 12 and the collimation line to the position Q is obtained, the distance L between the surveying instrument 10 and the marker 12, the distance L1 between the surveying instrument 10 and the position Q, and the pillar. The position of the member core P may be calculated geometrically from the length of the diameter of 11.

That is, when the building structural material is a columnar building structural material, in the first measurement step, the marker 12 is collimated to acquire prism survey data, and the columnar building structural material having the same height as the marker 12 is used. It is configured to collimate a point on the outer circumference and acquire non-prism survey data, and the member core position calculation step includes the prism survey data and non-prism survey data acquired in the first measurement step, and a columnar building structural material. It is configured to calculate the current position of the member core of the columnar building structural material based on the radius of

In the first correction calculation step, the current position of the axis P of the pillar 11 is calculated in the member core position calculation step based on the prism survey data for the marker 12 acquired in the first measurement step, so that the axis P is designed. The correction direction and the correction amount with respect to the position can be calculated. The correction direction includes four directions of north, south, east, and west in a plan view, and a height direction in a front view.

In the second correction calculation step, the surveying instrument 10 constantly collimates the design position of the axis P without collimating the marker 12, so that the correction direction and the correction amount are as in the first correction calculation step described above. Cannot be calculated.

Therefore, in the second correction calculation step, the image position of the marker 12 is extracted by performing matching processing between the reference image and the reference image acquired in the first measurement step, and the image of the marker 12 included in the reference image is extracted from the surveying instrument 10. The correction amount and the correction direction are calculated based on the angle φ formed by the position and the image position corresponding to the collimation direction of the reference image and the non-prism survey data.

FIG. 3A shows the reference image acquired in the first measurement step, and FIG. 3B shows the collimation direction switched to the design position in the collimation direction switching step and acquired in the second measurement step. A reference image is shown. The symbol CP indicates a collimation point, and the alternate long and short dash line indicates the design position of the pillar 11. The image of the marker 12 appears at the center position of the reference image indicating the collimation direction of the surveying instrument 10. Further, FIG. 3C shows a virtual diagram showing the positional relationship between the surveying instrument 10, the pillar 11 at the current position, and the pillar 11D (indicated by the alternate long and short dash line) at the design position in a plan view.

Therefore, by performing matching processing with the reference image using the reference image as the template image, the pixel position of the center of the marker 12 included in the reference image can be specified. The deviation between the position of the center pixel of the marker 12 on the reference image and the center position of the reference image corresponds to the amount of deviation Δx in the left-right direction and the amount of deviation Δz in the height direction. If the marker 12 can be identified from the reference image, the template image including the marker 12 is not limited to the reference image, and may be an image prepared in advance.

Since the deviation angle k per pixel between the position of the center pixel of the marker 12 on the reference image and the center position of the reference image is known, the deviation angles φx and φz corresponding to the deviation amounts Δx and Δz are the same. It can be calculated by the following formulas.
φx = k × nx (nx is the number of pixels in the x direction)
φz = k × nz (nz is the number of pixels in the z direction)
The bias angle k per pixel is a value peculiar to the image pickup apparatus 10b and can be obtained by actually measuring it in advance, and can be obtained by dividing the angle of view of the image pickup apparatus 10b by the number of pixels in the width direction of the image.

Since the distance L between the surveying instrument 10 and the pillar 11 is included in the non-prism survey data, Δx = Ltanφx and Δz = Ltanφz.

Since the design position of the axis P exists in the collimation direction of the surveying instrument 10, the distance L to the surface of the pillar 11 at the current position imaged at the center position of the reference image is included in the non-prism survey data. From the coordinates of the collimation point CP of the column 11 at the current position and the offset value with respect to the marker 12, the deviation Δy in the depth direction from the column 11D at the design position can be calculated.

The correction guide image 50 is illustrated in FIGS. 4 (a) to 4 (c). The first correction guide image and the second correction guide image are basically correction guide images having the same configuration.
The correction guide image 50 is formed around the azimuth lines 52 and 53 intersecting at the design position 51 of the column core, the column core marker 54 indicating the current position of the column core calculated from the measured value, and the design position 51 of the column core. East and west for adjusting the column core marker 54 to move to the design position 51, the first region 55 which is partitioned and shows the allowable range, the second region 56 which is partitioned outside the first region 55 and shows the non-allowable region. A display showing the north-south correction direction and the correction amount (arrows indicate the correction direction and the numerical values indicate the correction amount) and the correction amount in the height direction (arrows indicate the correction direction and the numerical values indicate the correction amount). The unit 57 is provided. In the present embodiment, the background of the screen is set to white, the azimuth lines 52 and 53 are set to black, the pillar core marker 12 is set to red, the first region 55 is set to blue, and the second region 56 is set to yellow.

Further, the correction guide image 50 includes a measurement start unit 58A for starting the measurement of the marker 12 installed on the pillar 11 by the surveying instrument 10, a collimation switching unit 58B for switching the collimation from the marker 12 to the design position, and stopping the measurement. Each touch switch unit includes a measurement stop unit 58C for instructing, a registration unit 58D for registering the column core position after the adjustment work is completed, and an end unit 58E for inputting the end of the adjustment work.

In FIG. 4A, since the pillar core marker 54 is displaced by 3 mm to the west, 4 mm to the south, and 3 mm downward from the set position 51, the pillar core marker 54 is 3 mm to the east, 4 mm to the north, and 3 mm to the top. The display unit 57 of the correction amount and the correction direction indicates that the pillar core marker 54 reaches the design position 51 if adjusted so as to move, and the pillar core marker 54 with respect to the first region 55 indicating the allowable range after adjustment is shown. Relative positions are shown.

In FIG. 4B, the building adjustment jig 13 is operated by the worker H to adjust the position of the column core marker 54 to a position corresponding to the design position 51 in the east-west direction, and slightly toward the design position in the vertical direction. It is shown that the position has been adjusted, and in FIG. 4C, the building adjustment jig 13 is operated by the worker H to adjust the position of the column core marker 54 in the north-south direction and enter the first region 25. It is shown. In addition, the scale including the permissible range may be displayed in the height direction as well. For example, in a bar graph that is long in the vertical direction, the center position is the design position, the allowable range is shown in the vertical direction across the design position, and the column core marker is displayed in one of the bar graphs in the vertical direction. May be good.

In the present embodiment, the first region 55 indicating the north, south, east, and west permissible ranges is displayed as a perfect circle with the permissible range as the radius centered on the design position 51, but the permissible range differs depending on the north, south, east, and west directions. It may be set. For example, it may be a rectangle centered on the reference position 21 or an ellipse.

Further, the range of the first area 55 indicating the allowable range is variably set according to the location of the pillar 11 to be built. The construction accuracy of the built-in pillars 11 is not always the same, and may differ for each pillar 11. For example, the construction accuracy of the structurally important pillars 11 and the non-structurally important pillars 11 may be different. Therefore, work efficiency can be improved. Therefore, by setting the range of the first area 55 variably according to the pillar 11 to be built, flexible construction support becomes possible. The same applies to the height direction.

Such a correction guide image is generated by the correction calculation device 20f and displayed on the display unit of the building support device 20, and is also displayed on the display device 30 possessed by the operator who operates the building adjustment jig. Will be done. That is, the display images of the building support device 20 and the display device 30 are shared.

The corrected guidance image may be simply transmitted to the display device 30 and displayed on the display screen of the display device 30 by the guidance image processing unit 30a of the display device 30, via an image sharing system server connected via the Internet 5. An image sharing system that displays the same image on both the building support device 20 and the display device 30 may be used.

Further, the building support device 20 itself is constructed as an application on the cloud server, and a plurality of or specific display devices 30 execute the application on the cloud server via the Internet 5 to function as the building support device 20. It may be configured. In this case, the surveying instrument 10 and the repeater are connected via the first communication IF, and the repeater and the construction support device 20 are connected via the second communication IF.

FIG. 6 shows a more detailed procedure of the construction support method.
When the building support application program is started up by the building support device 20 (SB1), the design file is downloaded from the building management server 40 and stored in the storage device (SB2). When the surveying instrument 10 is activated and communication is established with the construction support device 20 (SB3), the surveying instrument 10 is initially set (SB4).

When the building support device 20 and the display device 30 are communicably connected and the measurement start switch 58A (see FIG. 4A) provided on the display screen of the display device 30 is operated, the target pillar 11 markers 12 are collimated. At this time, since an image by the image pickup device 10b provided in the surveying instrument 10 is displayed on the display screen of the display device 30, the surveying instrument 10 can be remotely controlled via the display device 30 based on the image. The marker 12 is correctly collimated. For example, the coordinates of the design axis input to the display device 30 are input to the surveying instrument 10 via the construction support device 20, and after the surveying instrument 10 collimates the design axis, the surveying instrument 10 is used. By activating the provided automatic tracking mechanism, the surveying instrument 10 can be collimated with the marker 12.

Then, the first measurement step is executed, the prism survey data is acquired (SB5), the member core position calculation step is executed (SB6), the first correction calculation step is executed (SB7), and the first correction guide image is displayed. It is generated and displayed on the display device 30 (SB8).

When the collimation changeover switch 58B (see FIG. 4A) provided on the display screen of the display device 30 is operated, the surveying instrument 10 switches to the non-prism mode, and the collimation direction switching step is executed (see FIG. 4A). SB9). After the first measurement step is executed, the surveying instrument 10 may be programmed so that the surveying instrument 10 automatically switches to the non-prism mode and collimates the design axis.

When the operator visually observes the first correction guide image displayed on the screen of the display device 30 and operates the building adjustment jig 13, and the adjustment is completed (the first area 55 indicating the allowable range of the first correction guide image). The adjustment is completed when the pillar core marker 54 is inserted in (SB11, Y), and the process proceeds to step SB17.

If the adjustment is not completed (SB11, N), the second measurement step is executed (SB12), the second correction calculation step is executed based on the acquired non-prism survey data (SB13), and the second correction guide is executed. An image is generated and displayed on the display device 30 (SB14).

The operator visually observes the second correction guide image displayed on the screen of the display device 30 and operates the building adjustment jig 13, and if the adjustment is not completed (the first indicating the allowable range of the first correction guide image). The adjustment is completed when the column core marker 54 enters the region 55) (SB16, N), and the processes of steps SB12 to SB15 are repeated.

When the adjustment is completed (SB16, Y), the processes from step SB5 to step SB16 are repeated for each pillar 11 until the construction of all the pillars 11 is completed (SB17, N).

When the construction of all the pillars 11 is completed (SB17, Y), the data showing the adjustment result of each pillar 11 is collected in the building support device 20 to generate an overall evaluation map (SB18), and the building support device 20 It is stored in the memory of (SB19), uploaded to the building management server 40, and stored in the management data storage area of the database (SB20).

Another embodiment will be described below.
In the above-described embodiment, the mode in which one marker 12 used for the building work is installed in each building structural material has been described, but each building structure as shown in FIGS. 7C and 7D has been described. The present invention can also be applied when a plurality of markers 12 are installed on the material and it is necessary to adjust the member core with respect to each marker 12.

That is, for each marker 12 installed corresponding to at least two member cores P set in the building structural material 11, a first measurement step, a member core position calculation step, and a first correction calculation step. And the first display step, and at least when the processing after the first adjustment step is executed for each lumber core P, the collimation direction of the surveying instrument 10 is supported by the collimation direction switching step. It may be configured to switch to the design position of the member core to be used, and the second measurement step, the second correction calculation step, the second display step, and the second adjustment step may be executed for each member core. Since the first correction guide image for each member core displayed in the first display step is stored in the memory, it is not necessary to repeat the first measurement step, the member core position calculation step, and the first correction calculation step.

For example, to explain the wall material shown in FIG. 7D as an example, after acquiring the prism survey data for the marker 12A, the prism survey data is acquired for the marker 12B, and the member cores PA and PB, respectively. The first correction guide image for is generated and displayed.

When the first adjustment step is executed on the member core PA and the second adjustment step is repeated from the second measurement step, the collimation direction of the surveying instrument 10 is switched to the design position of the member core PA. Further, when the first adjustment step is executed on the member core PB and the second adjustment step is repeated from the second measurement step, the collimation direction of the surveying instrument 10 is switched to the design position of the member core PB. The values of the cores PA and PB of each member are downloaded in advance from the building management server 40 to the building support device 20.

When it is necessary to repeat the above-mentioned adjustment work for the member cores PA and PB a plurality of times, the collimation direction may be switched to the design position of the member core PA or the member core PB each time.

Based on the correction amount and correction direction for each member core position calculated in the first correction calculation step, it is also possible to execute the processing after the first adjustment step only for the member core determined to be necessary for adjustment. .. It is also possible to determine the order in which the processes after the first adjustment step are executed based on the correction amount and the correction direction for each member core position.

For example, the processing after the first adjustment step can be executed in order from the member core having the larger correction amount, and the processing after the first adjustment step is executed with priority given to the member cores having the same correction direction. It is possible to execute the processing after the first adjustment step by giving priority to the member core whose correction direction is different from that of the other member cores. Further, the execution order of the processes after the first adjustment step can be determined based on the combination of the correction amount and the correction direction.

FIG. 9 shows the procedure of the above-mentioned construction support method. In the construction support method, first, each process of the first measurement step, the member core position calculation step, the first correction calculation step, and the first display step is executed (SA20) for all member cores (markers) ( SA21).

Next, the member cores that need to be adjusted are selected based on the correction amount and the correction direction for each member core position (SA22), and the collimation direction switching step (SA23) and the first adjustment step and (SA24) are executed. Then, each step of the second measurement step, the second correction calculation step, the second display step, and the second adjustment step (SA25) is repeatedly executed until the adjustment is made within a predetermined allowable range (SA26). The process from step SA22 to step SA26 is repeated until the adjustment of the member core requiring adjustment is completed (SA27).

In the first correction calculation step, an example in which the correction direction and the correction amount are calculated based on the prism survey data for the marker 12 and the design position of the member core has been described, but the procedure described in the second correction calculation step is the first correction. It may be adopted in the calculation step to calculate the correction direction and the correction amount.

In the embodiment described above, the building support method and the building support system for each building structural material have been described, but the present invention is not limited to the individual building support for each building structural material, and a plurality of building structural materials. It can also be applied to the group of.

For example, taking columns as an example, the first measurement step, members, are applied to all or a plurality of columns temporarily fixed to the base downstairs to which the cross beams are connected after the building is completed via the building adjustment jig. Each process of the core position calculation step, the first correction calculation step, and the first display step is executed to calculate the correction direction and the correction amount of the member core for each pillar 11, and based on the result, for example, it is shown in FIG. Such a completed drawing showing the correction direction and the correction amount for each pillar may be displayed on the display device, the pillars requiring adjustment may be specified based on the state, and the adjustment order for each pillar may be formulated. .. It is preferable that the display device is arranged not only in the worker but also in the construction office so that the site manager can identify the pillars that need to be adjusted and formulate the order of adjustment for each pillar.

The collimation direction switching step and the first adjustment step are executed for the pillar to be adjusted, and each step of the second measurement step, the second correction calculation step, the second display step, and the second adjustment step is performed. It is repeatedly executed until it is adjusted to a predetermined allowable range, and the above process is repeated until the adjustment of the member core that needs to be adjusted is completed. The above method may be applied to a combination of different types of building structural materials.

FIG. 10 shows a plan view showing the reference positions of some pillars 11 built on a predetermined floor and the positions of the cores of the pillars after temporary fixing, together with the deviation amount and direction with respect to each reference position. There is. The correction amount and the correction direction calculated in the first correction calculation step are shown for the pillars in which the white arrows and the black-painted arrows are shown from each side of the rectangular shape indicating the pillars. The value indicated at the tip of the black arrow is the amount of deviation. Based on such a finished drawing, adjustment work can be performed in consideration of the overall balance of construction accuracy.

All of the above-described embodiments are merely one aspect of the present invention, and the description does not limit the technical scope of the present invention, and the specific configuration of each part is appropriately configured within the range in which the effects of the present invention are exhibited. Needless to say, it can be modified and designed.

The present invention relates to a building support method and a building support system.

Patent Document 1 proposes a construction support system capable of promptly and appropriately performing column adjustment work by an operator. The construction support system includes a surveying instrument, a first mobile device, and a second mobile device.

Japanese Patent No. 6433033 JP-A-2019-7260

However, in the construction support system disclosed in Patent Document 1, in the process of adjusting the posture of the pillar with the adjustment jig, the measurer always waits in the vicinity of the surveying instrument to install the prism installed on the pillar. It is necessary to constantly collimate and operate the first mobile device, which poses a problem from the viewpoint of controlling labor costs.

In addition, in the process of the operator operating the building adjustment jig attached to the pillar based on the display image displayed on the second mobile device, it takes time for the measurer to operate the surveying instrument and collimate the prism. Therefore, it takes a certain amount of time for the adjustment work, and more efficient adjustment is required.

When the automatic tracking type total station disclosed in Patent Document 2 is used, a time response delay for automatic tracking occurs in the process of adjusting the posture of the pillar by the adjustment jig, and the second mobile device has a delay. There is a problem that the correction guide image to be displayed and the timing of automatic tracking are out of alignment and cannot be adjusted properly.

Therefore, if the posture of the pillar is adjusted with the adjustment jig based on the correction guide image and then the automatic tracking function is activated by remote control, the above-mentioned inconvenience does not occur, but the time delay required for automatic tracking is delayed. There was an impact, and there was a problem that the adjustment work by the operator was delayed accordingly.

Then, not only pillar materials such as steel columns, but also beam materials, wall materials, diagonal materials, and building structural materials such as columns and assembly of beam materials are used by using a building adjustment jig. There was the same problem as described above when positioning and adjusting the building structural material in the above position.

An object of the present invention is a construction support method and construction capable of performing adjustment work of building structural materials by a worker as quickly and appropriately as possible while suppressing labor costs in view of the above-mentioned conventional problems. The point is to provide a support system.

In order to achieve the above object, the first characteristic configuration of the construction support method according to the present invention is a construction support method for supporting a worker who adjusts a building structural material so as to be within a predetermined construction accuracy. , Using a surveying instrument equipped with an imaging device in which the collimation direction and the image center have a predetermined positional relationship, collimate a marker prism installed at a position having a predetermined positional relationship with the member core of the building structural material. The first measurement step of acquiring the prism survey data and the imaging data including the marker prism as a reference image, and the member core of the building structural material based on the prism survey data acquired in the first measurement step. Calculated in the member core position calculation step for calculating the current position, the first correction calculation step for calculating the correction amount and the correction direction for guiding the current position of the member core toward the design position, and the first correction calculation step.

The operator adjusts the building based on the second display step of displaying the calculated correction amount and the second correction guide image indicating the correction direction on the display device and the second correction guide image displayed in the second display step. It includes a second adjustment step for operating the jig, and is configured to repeat a series of steps from the second measurement step to the second adjustment step.

In the first measurement step, the marker prism installed on the building structural material is collimated by the surveying instrument to acquire the prism survey data, and the imaging data including the marker prism is acquired. Based on this, the current position of the member core of the building structural material is calculated. In the first correction calculation step, the correction amount and the correction direction for guiding the current position of the member core toward the design position are calculated, and in the first display step, the first correction guide image showing the correction amount and the correction direction is displayed on the display device. Will be done.

The collimation direction of the surveying instrument is switched from the marker prism to the design position in the collimation direction switching step, and the current position of the member core is set to the design position based on the first correction guide image displayed on the display device in the first adjustment step. The building adjustment jig attached to the building structural material is operated by the operator to bring it closer.

Next, the second measurement step is executed, and the non-prism survey data is acquired by the surveying instrument while maintaining the collimation direction switched to the design position in the collimation direction switching step, and the captured data is further acquired as a reference image. NS. Based on the position of the marker prism extracted from the reference image and the non-prism survey data in the second correction calculation step, the correction amount and the correction direction for guiding the current position of the member core toward the design position are calculated, and the second correction amount is calculated. In the display step, the correction amount and the correction direction are displayed as the second correction guide image, and in the second adjustment step, the worker uses the building structural material to bring the current position of the member core closer to the design position based on the second correction guide image. The installed building adjustment jig is operated. By repeating a series of steps from the second measurement step to the second adjustment step, the current position of the member core is adjusted toward the design position.

In the series of steps from the second measurement step to the second adjustment step, the collimation direction of the surveying instrument is fixed at the design position and is not changed, so that the time required for the survey is shortened and the adjustment work can be performed efficiently. ing to so that.

In the second correction calculation step, the image position of the marker prism included in the reference image is extracted by performing matching processing between the reference image and the reference image, and the image position of the marker prism included in the reference image and the reference image are extracted from the surveying instrument. The correction amount and correction direction are calculated based on the angle formed by the image position corresponding to the collimation direction and the non-prism survey data, that is, the distance to the surface of any of the building structural materials.

In the second feature configuration, in addition to the first feature configuration described above, when the building structural material is a columnar building structural material, the first measurement step collimates the marker prism with the prism. The member core position calculation step is configured to acquire survey data and acquire non-prism survey data by collimating a point on the outer periphery of the columnar building structural material having the same height as the marker prism. A point configured to calculate the current position of the member core of the columnar building structural material based on the prism surveying data and the non-prism surveying data acquired in the first measurement step and the radius of the columnar building structural material. It is in.

In the first measurement step, prism survey data collimating the marker prism and non-prism survey data collimating a point on the outer circumference of the columnar building structural material having the same height as the marker prism are acquired, and the member core position is calculated. In each step, the current position of the member core of the columnar building structural material is geometrically calculated from the respective position data and the radius of the columnar building structural material.

The third feature configuration is, in addition to the first feature configuration described above, for each marker prism installed corresponding to at least two member cores set in the building structural material. When the 1 measurement step, the member core position calculation step, the first correction calculation step, and the first display step are executed, and the processing after the first adjustment step is executed for a plurality of member cores. The point is that the collimation direction of the surveying instrument is switched to the design position of the corresponding member core by the collimation direction switching step.

When at least two member cores are set for the building structural material, for example, a beam member or a wall member, it is necessary to adjust the position with respect to each member core. Even in such a case, the above-mentioned first measurement step, member core position calculation step, first correction calculation step, and first display are performed on the markers installed corresponding to at least two member cores.

It is provided with a second storage unit 20e for storing the imaged data. The meaning of "to collimate the design position of the member core" is to collimate the position where the marker 12 attached to the building structural material exists when it is assumed that the member core exists at the design position. This means collimating the position of the member core at the same height as the mounting height of the marker 12.

[How to support the construction of pillars]
A method of supporting the construction of pillar lumber using the above-mentioned construction support system will be described.
As shown in FIG. 5, the construction support methods include a first measurement step and (SA1), a member core position calculation step and (SA2), a first correction calculation step and (SA3), and a first display step and (SA4). , Collimation direction switching step and (SA5), first adjustment step and (SA6), second measurement step and (SA7), second correction calculation step and (SA8), second display step and (SA9), second It includes an adjustment step and (SA10).

The prism survey data is acquired and the imaging data including the marker 12 is acquired as a reference image and stored in the first storage unit 20d.

The member core position calculation step (SA2) is executed by the correction calculation device 20f, and the current position of the pillar core P of the pillar 11 is calculated based on the prism survey data acquired in the first measurement step.

The first correction calculation step (SA3) is executed by the first correction calculation unit 20g provided in the correction calculation device 20f, and calculates the correction amount and the correction direction for guiding the current position of the column core P toward the design position. , The first correction guide image is generated and stored.

The first display step (SA4) is executed by the first correction calculation unit 20g and the guide image display processing unit 30a of the display device 30, and the first correction guide image showing the correction amount and the correction direction calculated in the first correction calculation step. Is displayed on the display device.

The collimation direction switching step (SA5) is executed by the survey control device 20c to switch the collimation direction of the surveying instrument 10 from the marker 12 to the design position.

The first adjustment step (SA6) is executed by the operator and operates the building adjustment jig 13 attached to the pillar 11 based on the first correction guide image displayed in the first display step.

The second measurement step (SA7) is executed by the survey control device 20c, and after the adjustment in the first adjustment step, the non-prism survey data is acquired while maintaining the collimation direction switched in the collimation direction switching step. At the same time, the captured data is acquired as a reference image and stored in the second storage unit 20e.

The second correction calculation step (SA8) is executed by the second correction calculation unit 20h provided in the correction calculation device 20f, and is based on the position of the marker 12 extracted from the reference image and the non-prism survey data. The correction amount and the correction direction for guiding the position toward the design position are calculated, and the second correction guide image is generated and stored.

The second display step (SA9) is executed by the second correction calculation unit 20h and the guide image display processing unit 30a of the display device 30, and the second correction guide image showing the correction amount and the correction direction calculated in the second correction calculation step. Is displayed on the display device.

The second adjustment step (SA10) is executed by the operator and operates the building adjustment jig 13 attached to the pillar 11 based on the second correction guide image displayed in the second display step.

If the adjustment cannot be made within the predetermined allowable range in the second adjustment step (SA10) (SA11, N), the process returns to step SA7 and the series of processes from the second measurement step to the second adjustment step in step SA10 is switched. Then, when the adjustment is made to a predetermined allowable range in the second adjustment step (SA10) (SA11, Y), the adjustment process of the pillar 11 is completed.

The collimation direction switching step (SA5) described above may be executed at any timing from the completion of the first measurement step (SA1) to the execution of the second measurement step. Specifically, at the end of the first measurement step (SA1), at the end of the member core position calculation step (SA2), at the end of the first correction calculation step (SA3), or at the end of the first display step (SA4). You may execute it with.

In the member core position calculation step, the position of the pillar core P can be automatically calculated from the relationship between the shape data of the known pillar 11 and the mounting position of the known marker 12.
For example, in the column 11 having a substantially rectangular plan view shown in FIG. 8A, the positional relationship between the marker 12 and the axis P is determined in advance by the offset values (x1, y1, z1), so that the position of the marker 12 ( When xm, ym, zm) is surveyed by the surveying instrument 10, the (x, y) coordinates of the axis P are (xm, ym + y1), and the (x, y, z) at the same height as the marker 12 is (x, y, z). ) The coordinates are obtained as (xm, ym + y1, zm).

The marker 12 may be attached in addition to the building structural material 11. When the building structural material 11 enters the blind spot and the surveying instrument 10 cannot collimate the building structural material 11, the marker 12 is located at a position where the surveying instrument 10 can collimate with the connecting member connected to the building structural material 11. May be installed. Even in this case, if the positional relationship between the member core of the building structural material 11 and the marker 12 is determined in advance by the offset values (x1, y1, z1), the position of the member core can be obtained in the same manner as described above.

Therefore, in order to position and adjust the building structural material 11 to the design position, the design position of the marker 12 can be calculated based on the design position of the member core, and the actual position of the marker 12 is the design position of the marker 12. It is also possible to operate the building adjustment jig 13 so as to approach. In that sense, the meaning of "colliming the design position of the member core" is to collimate the position where the marker 12 attached to the building structural material exists, assuming that the member core exists at the design position. Alternatively, it has been described above that the position of the member core having the same height as the mounting height of the marker 12 is collimated.

In the slanted lumber 11 of FIG. 7 (b), the slanted lumber 11 of FIG. 7 (c), and the wall material 11 of FIG. 7 (d), the positional relationship between the marker 12 and the member core P is determined in advance by an offset value in the same manner as described above. ing.

As shown in FIG. 8B, in the pillar 11 whose building structural material is circular in a plan view, the positional relationship between the marker 12 and the member core P cannot be specified by an offset value. Therefore, the surveying instrument 10 is used to acquire the prism survey data for the marker 12, and the non-prism survey data is acquired for the position Q separated from the marker 12 along the peripheral surface at the same height as the marker 12. Calculate the position of the member core P with.

The intersection of the radius circle of the pillar 11 centered on the position of the marker 12 and the radius circle of the pillar 11 centered on the position Q can be calculated as the position of the member core P.

Further, the angle θ between the collimation line from the surveying instrument 10 to the marker 12 and the collimation line to the position Q is obtained, the distance L between the surveying instrument 10 and the marker 12, the distance L1 between the surveying instrument 10 and the position Q, and the pillar. The position of the member core P may be calculated geometrically from the length of the diameter of 11.

That is, when the building structural material is a columnar building structural material, in the first measurement step, the marker 12 is collimated to acquire prism survey data, and the columnar building structural material having the same height as the marker 12 is used. It is configured to collimate a point on the outer circumference and acquire non-prism survey data, and the member core position calculation step includes the prism survey data and non-prism survey data acquired in the first measurement step, and a columnar building structural material. It is configured to calculate the current position of the member core of the columnar building structural material based on the radius of

In the first correction calculation step, the current position of the axis P of the pillar 11 is calculated in the member core position calculation step based on the prism survey data for the marker 12 acquired in the first measurement step, so that the axis P is designed. The correction direction and the correction amount with respect to the position can be calculated. The correction direction includes four directions of north, south, east, and west in a plan view, and a height direction in a front view.

In the second correction calculation step, the surveying instrument 10 constantly collimates the design position of the axis P without collimating the marker 12, so that the correction direction and the correction amount are as in the first correction calculation step described above. Cannot be calculated.

Therefore, in the second correction calculation step, the image position of the marker 12 is extracted by performing matching processing between the reference image and the reference image acquired in the first measurement step, and the image of the marker 12 included in the reference image is extracted from the surveying instrument 10. The correction amount and the correction direction are calculated based on the angle φ formed by the position and the image position corresponding to the collimation direction of the reference image and the non-prism survey data.

FIG. 3A shows the reference image acquired in the first measurement step, and FIG. 3B shows the collimation direction switched to the design position in the collimation direction switching step and acquired in the second measurement step. A reference image is shown. The symbol CP indicates a collimation point, and the alternate long and short dash line indicates the design position of the pillar 11. The image of the marker 12 appears at the center position of the reference image indicating the collimation direction of the surveying instrument 10. Further, FIG. 3C shows a virtual diagram showing the positional relationship between the surveying instrument 10, the pillar 11 at the current position, and the pillar 11D (indicated by the alternate long and short dash line) at the design position in a plan view.

Therefore, by performing matching processing with the reference image using the reference image as the template image, the pixel position of the center of the marker 12 included in the reference image can be specified. The deviation between the position of the center pixel of the marker 12 on the reference image and the center position of the reference image corresponds to the amount of deviation Δx in the left-right direction and the amount of deviation Δz in the height direction. If the marker 12 can be identified from the reference image, the template image including the marker 12 is not limited to the reference image, and may be an image prepared in advance.

Since the deviation angle k per pixel between the position of the center pixel of the marker 12 on the reference image and the center position of the reference image is known, the deviation angles φx and φz corresponding to the deviation amounts Δx and Δz are the same. It can be calculated by the following formulas.
φx = k × nx (nx is the number of pixels in the x direction)
φz = k × nz (nz is the number of pixels in the z direction)
The bias angle k per pixel is a value peculiar to the image pickup apparatus 10b and can be obtained by actually measuring it in advance, and can be obtained by dividing the angle of view of the image pickup apparatus 10b by the number of pixels in the width direction of the image.

Since the distance L between the surveying instrument 10 and the pillar 11 is included in the non-prism survey data, Δx = Ltanφx and Δz = Ltanφz.

Since the design position of the axis P exists in the collimation direction of the surveying instrument 10, the distance L to the surface of the pillar 11 at the current position imaged at the center position of the reference image is included in the non-prism survey data. From the coordinates of the collimation point CP of the column 11 at the current position and the offset value with respect to the marker 12, the deviation Δy in the depth direction from the column 11D at the design position can be calculated.

The correction guide image 50 is illustrated in FIGS. 4 (a) to 4 (c). The first correction guide image and the second correction guide image are basically correction guide images having the same configuration.
The correction guide image 50 is formed around the azimuth lines 52 and 53 intersecting at the design position 51 of the column core, the column core marker 54 indicating the current position of the column core calculated from the measured value, and the design position 51 of the column core. East and west for adjusting the column core marker 54 to move to the design position 51, the first region 55 which is partitioned and shows the allowable range, the second region 56 which is partitioned outside the first region 55 and shows the non-allowable region. A display showing the north-south correction direction and the correction amount (arrows indicate the correction direction and the numerical values indicate the correction amount) and the correction amount in the height direction (arrows indicate the correction direction and the numerical values indicate the correction amount). The unit 57 is provided. In the present embodiment, the background of the screen is set to white, the azimuth lines 52 and 53 are set to black, the pillar core marker 54 is set to red, the first region 55 is set to blue, and the second region 56 is set to yellow.

Further, the correction guide image 50 includes a measurement start unit 58A for starting the measurement of the marker 12 installed on the pillar 11 by the surveying instrument 10, a collimation switching unit 58B for switching the collimation from the marker 12 to the design position, and stopping the measurement. Each touch switch unit includes a measurement stop unit 58C for instructing, a registration unit 58D for registering the column core position after the adjustment work is completed, and an end unit 58E for inputting the end of the adjustment work.

In FIG. 4 (a), 3 mm pillar core markers 54 W with respect to the design position 51, since the shifted 3 mm 4 mm, down to the south, 3 mm to Hashirashin marker 54 to the east, 4 mm north upward It is shown on the display unit 57 of the correction amount and the correction direction that the pillar core marker 54 reaches the design position 51 if adjusted so as to move by 3 mm, and the pillar core marker 54 with respect to the first region 55 indicating the allowable range after adjustment is shown. The relative position of is shown.

In FIG. 4B, the building adjustment jig 13 is operated by the worker H to adjust the position of the column core marker 54 to a position corresponding to the design position 51 in the east-west direction, and slightly toward the design position in the vertical direction. indicated that the position adjustment, in FIG. 4 (c), the construction purse adjustment jig 13 is pillar core markers 54 are operated enters the first region 5 5 is alignment with the north-south direction by the operator H Is shown. In addition, the scale including the permissible range may be displayed in the height direction as well. For example, in a bar graph that is long in the vertical direction, the center position is the design position, the allowable range is shown in the vertical direction across the design position, and the column core marker is displayed in one of the bar graphs in the vertical direction. May be good.

In the present embodiment, the first region 55 indicating the north, south, east, and west permissible ranges is displayed as a perfect circle with the permissible range as the radius centered on the design position 51, but the permissible range differs depending on the north, south, east, and west directions. It may be set. For example, it may be a rectangle centered on the design position 51 or an ellipse.

Further, the range of the first area 55 indicating the allowable range is variably set according to the location of the pillar 11 to be built. The construction accuracy of the built-in pillars 11 is not always the same, and may differ for each pillar 11. For example, the construction accuracy of the structurally important pillars 11 and the non-structurally important pillars 11 may be different. Therefore, work efficiency can be improved. Therefore, by setting the range of the first area 55 variably according to the pillar 11 to be built, flexible construction support becomes possible. The same applies to the height direction.

Such a correction guide image is generated by the correction calculation device 20f and displayed on the display unit of the building support device 20, and is also displayed on the display device 30 possessed by the operator who operates the building adjustment jig. Will be done. That is, the display images of the building support device 20 and the display device 30 are shared.

FIG. 6 shows a more detailed procedure of the construction support method.
When the building support application program is started up by the building support device 20 (SB1), the design file is downloaded from the building management server 40 and stored in the storage device (SB2). When the surveying instrument 10 is activated and communication is established with the construction support device 20 (SB3), the surveying instrument 10 is initially set (SB4).

When the building support device 20 and the display device 30 are communicably connected and the measurement start unit 58A (see FIG. 4A) provided on the display screen of the display device 30 is operated, the target pillar 11 markers 12 are collimated. At this time, since an image by the image pickup device 10b provided in the surveying instrument 10 is displayed on the display screen of the display device 30, the surveying instrument 10 can be remotely controlled via the display device 30 based on the image. The marker 12 is correctly collimated. For example, the coordinates of the design axis input to the display device 30 are input to the surveying instrument 10 via the construction support device 20, and after the surveying instrument 10 collimates the design axis, the surveying instrument 10 is used. By activating the provided automatic tracking mechanism, the surveying instrument 10 can be collimated with the marker 12.

Then, the first measurement step is executed, the prism survey data is acquired (SB5), the member core position calculation step is executed (SB6), the first correction calculation step is executed (SB7), and the first correction guide image is displayed. It is generated and displayed on the display device 30 (SB8).

When the collimation changeover switch 58B (see FIG. 4A) provided on the display screen of the display device 30 is operated, the surveying instrument 10 switches to the non-prism mode, and the collimation direction switching step is executed (see FIG. 4A). SB9). After the first measurement step is executed, the surveying instrument 10 may be programmed so that the surveying instrument 10 automatically switches to the non-prism mode and collimates the design axis.

When the operator visually observes the first correction guide image displayed on the screen of the display device 30 and operates the building adjustment jig 13, and the adjustment is completed (the first area 55 indicating the allowable range of the first correction guide image). The adjustment is completed when the pillar core marker 54 is inserted in (SB11, Y), and the process proceeds to step SB17.

If the adjustment is not completed (SB11, N), the second measurement step is executed (SB12), the second correction calculation step is executed based on the acquired non-prism survey data (SB13), and the second correction guide is executed. An image is generated and displayed on the display device 30 (SB14).

The operator visually observes the second correction guide image displayed on the screen of the display device 30 and operates the building adjustment jig 13, and if the adjustment is not completed (the first indicating the allowable range of the first correction guide image). The adjustment is completed when the column core marker 54 enters the region 55) (SB16, N), and the processes of steps SB12 to SB15 are repeated.

When the adjustment is completed (SB16, Y), the processes from step SB5 to step SB16 are repeated for each pillar 11 until the construction of all the pillars 11 is completed (SB17, N).

When the construction of all the pillars 11 is completed (SB17, Y), the data showing the adjustment result of each pillar 11 is collected in the building support device 20 to generate an overall evaluation map (SB18), and the building support device 20 It is stored in the memory of (SB19), uploaded to the building management server 40, and stored in the management data storage area of the database (SB20).

Another embodiment will be described below.
In the above-described embodiment, the mode in which one marker 12 used for the building work is installed in each building structural material has been described, but each building structure as shown in FIGS. 7C and 7D has been described. The present invention can also be applied when a plurality of markers 12 are installed on the material and it is necessary to adjust the member core with respect to each marker 12.

That is, for each marker 12 installed corresponding to at least two member cores P set in the building structural material 11, a first measurement step, a member core position calculation step, and a first correction calculation step. And the first display step, and at least when the processing after the first adjustment step is executed for each lumber core P, the collimation direction of the surveying instrument 10 is supported by the collimation direction switching step. It may be configured to switch to the design position of the member core to be used, and the second measurement step, the second correction calculation step, the second display step, and the second adjustment step may be executed for each member core. Since the first correction guide image for each member core displayed in the first display step is stored in the memory, it is not necessary to repeat the first measurement step, the member core position calculation step, and the first correction calculation step.

For example, to explain the wall material shown in FIG. 7D as an example, after acquiring the prism survey data for the marker 12A, the prism survey data is acquired for the marker 12B, and the member cores PA and PB, respectively. The first correction guide image for is generated and displayed.

When the first adjustment step is executed on the member core PA and the second adjustment step is repeated from the second measurement step, the collimation direction of the surveying instrument 10 is switched to the design position of the member core PA. Further, when the first adjustment step is executed on the member core PB and the second adjustment step is repeated from the second measurement step, the collimation direction of the surveying instrument 10 is switched to the design position of the member core PB. The values of the cores PA and PB of each member are downloaded in advance from the building management server 40 to the building support device 20.

When it is necessary to repeat the above-mentioned adjustment work for the member cores PA and PB a plurality of times, the collimation direction may be switched to the design position of the member core PA or the member core PB each time.

Based on the correction amount and correction direction for each member core position calculated in the first correction calculation step, it is also possible to execute the processing after the first adjustment step only for the member core determined to be necessary for adjustment. .. It is also possible to determine the order in which the processes after the first adjustment step are executed based on the correction amount and the correction direction for each member core position.

For example, the processing after the first adjustment step can be executed in order from the member core having the larger correction amount, and the processing after the first adjustment step is executed with priority given to the member cores having the same correction direction. It is possible to execute the processing after the first adjustment step by giving priority to the member core whose correction direction is different from that of the other member cores. Further, the execution order of the processes after the first adjustment step can be determined based on the combination of the correction amount and the correction direction.

In the construction support method, first, each process of the first measurement step, the member core position calculation step, the first correction calculation step, and the first display step is executed (SA20) for all member cores (markers) ( SA21).

Next, the member cores that need to be adjusted are selected based on the correction amount and the correction direction for each member core position (SA22), and the collimation direction switching step (SA23) and the first adjustment step and (SA24) are executed. Then, each step of the second measurement step, the second correction calculation step, the second display step, and the second adjustment step (SA25) is repeatedly executed until the adjustment is made within a predetermined allowable range (SA26). The process from step SA22 to step SA26 is repeated until the adjustment of the member core requiring adjustment is completed (SA27).

In the first correction calculation step, an example in which the correction direction and the correction amount are calculated based on the prism survey data for the marker 12 and the design position of the member core has been described, but the procedure described in the second correction calculation step is the first correction. It may be adopted in the calculation step to calculate the correction direction and the correction amount.

In the embodiment described above, the building support method and the building support system for each building structural material have been described, but the present invention is not limited to the individual building support for each building structural material, and a plurality of building structural materials. It can also be applied to the group of.
