In the first embodiment, the operation unit 13 is provided on the surface 11 a of the housing 11. The operation unit 13 may be provided independently of the image display screen 12, and is configured as a screen displayed on the image display screen 12 by mounting a touch panel function on the image display screen 12. There may be.

  Although not shown, the imaging unit 14 includes an imaging optical system 14a (see FIG. 3) including at least one lens, and an imaging element 14b (see FIG. 3) provided at an imaging position of the imaging optical system 14a. Are fixedly accommodated in the housing 11 and a scene (scene image Ps) outside the housing 11 can be acquired. In the first embodiment, the imaging unit 14 is provided with the objective lens 14c (see FIG. 2) of the photographing optical system 14a exposed to the outside on the back surface 11b of the housing 11, and the photographing optical axis OA (see FIG. 2). ) Is set in a direction orthogonal to the back surface 11b. Therefore, in the first embodiment, when the scene image Ps acquired by the imaging unit 14 is displayed on the image display screen 12, the scenery on the extension line of the line of sight of the user who is viewing the image display screen 12 is used as the scene image Ps. It is displayed on the image display screen 12. In the imaging unit 14, although not shown, the center position of the imaging element 14b is set so as to be positioned on the imaging optical axis OA of the imaging optical system 14a.

  The tilt sensor 15 (see FIG. 3) detects the tilt angle θ (see FIG. 5) from the reference state of the vertical indicator 10 (housing 11) and the tilt direction (hereinafter also referred to as a tilted state). In the first embodiment, an acceleration sensor that can measure acceleration is used, and it is possible to detect the direction of gravity, that is, to measure the degree of inclination with respect to the direction of gravity. For this reason, the inclination sensor 15 can measure the inclination state (degree of inclination) of the imaging unit 14 (its imaging optical axis OA (see FIG. 2)) fixedly provided in the housing 11 with respect to the gravity direction. And functions as an inclination detection means. In the first embodiment, the reference state of the vertical indicator 10 (housing 11) is a state in which the photographing optical axis OA (see FIG. 2) of the imaging unit 14 coincides vertically downward, that is, the front surface 11a and the back surface of the housing 11. 11b is set in a state parallel to the horizontal plane. Thereby, in Example 1, the inclination sensor 15 is around one direction along the horizontal plane from the state in which the image display screen 12 is directed upward in the vertical direction (see FIG. 1) (see arrow A1 (hereinafter also referred to as roll direction). )) And the vertical direction indicator 10 with respect to the direction of gravity around the other direction orthogonal to the one direction along the horizontal plane (refer to arrow A2 below, also referred to as pitch direction). 10 (housing 11) can be detected at least. Note that the tilt sensor 15 may be formed of, for example, a gyro sensor as long as it can detect the tilt state from the reference state of the vertical indicator 10 (housing 11), and is limited to the first embodiment. It is not something.

  As shown in FIG. 3, the control unit 16 generates image data based on a signal from the imaging unit 14, display processing for displaying a spectacle image Ps based on the generated image data on the image display screen 12, and a tilt sensor. Control of the operation of the vertical indicator 10 such as the determination processing of the tilt state from the reference state of the vertical indicator 10 (housing 11) based on the signal from 15 is comprehensively performed by a program stored in the storage unit 16a. Is. The control unit 16 generates image data based on a signal from the image pickup device 14b of the image pickup unit 14, stores the image data in the storage unit 16a as appropriate, and sends a spectacle image Ps based on the image data to the vertical indicator. 10 (case 11) is appropriately displayed on the image display screen 12 provided on the surface 11a side. A detection signal is input to the control unit 16 from the operation unit 13 or the inclination sensor 15.

  The control unit 16 can perform control processing for the vertical position indicating function in addition to the basic control described above. As shown in FIG. 4, this vertical position indication function is configured to display a vertical position indication symbol 17 superimposed on the scene image Ps when the scene image Ps acquired by the imaging unit 14 is displayed on the image display screen 12. Is displayed. The vertical position marking symbol 17 indicates the position below the vertical position so that the position corresponding to the vertically lower position of the positioning reference portion B of the vertical indicator 10 can be specified in the scene image Ps acquired by the imaging unit 14. In the first embodiment, it is a cross symbol. The positioning reference part B is a reference point for instructing the vertically downward direction in the vertical pointing device 10, and the vertical pointing device 10 according to the present invention uses the sight image Ps acquired by the imaging unit 14 to indicate the vertical position indication symbol. 17 in the reference state of the vertical indicator 10 (the image pickup unit 14 fixed to the casing 11), and within the range that can be acquired as the scene image Ps by the image pickup unit 14 when viewed in horizontal coordinates. It is set so that the vertically lower position is located (within the angle of view of the imaging unit 14). In the first embodiment, the positioning reference part B is a predetermined position on the photographing optical axis OA in the photographing optical system 14a, and is a focal position on the photographing optical axis OA in the photographing optical system 14a (FIG. 2). Here, since the center position of the image sensor 14b is set to be located on the photographing optical axis OA of the photographing optical system 14a in the image pickup section 14, the vertical downward position of the positioning reference section B is the vertical indicator. Reference state 10 is horizontal, that is, when the imaging optical axis OA (see FIG. 2) of the imaging unit 14 is matched in the vertical direction and the imaging unit 14 acquires a vertically downward scene (scene image Ps), the scene image Located in the center of Ps. For this reason, the display position of the vertical position indication symbol 17 on the image display screen 12 in the reference state in which the vertical pointing device 10 is horizontal is the central position of the scene image Ps, and the central position is the vertical position of the vertical position indication symbol 17. This is the display reference position.

  When the detection signal from the tilt sensor 15 is input, the control unit 16 tilts the vertical indicator 10 (housing 11) from the reference state, in other words, the imaging optical axis OA in the vertical direction in the imaging unit 14. The tilt angle θ (see FIG. 5) and the tilt direction (each component in the roll direction (see arrow A1) and pitch direction (see arrow A2)) from the matching state can be acquired. Here, as shown in FIG. 5, assuming that the angle of view in the imaging unit 14 (the region sandwiched between two straight lines cl) is constant, each of the distances acquired at different positions on the photographing optical axis OA is obtained. In the image (ps1, ps2, ps3), the ratio of the distance from the location (c1, c2, c3) where the photographing optical axes OA intersect to the location (v1, v2, v3) where the vertical line vl intersects is equal. From this, the inclination angle θ from the vertical direction of the vertical pointing device 10, that is, the photographing optical axis OA is the distance on the scene image Ps in consideration of the angle of view, in other words, the imaging element 14b of the imaging unit 14 in consideration of the angle of view. It can be converted into the above interval. In the first embodiment, since the vertical display reference position (the vertical lower position of the positioning reference portion B when the vertical indicator 10 is in the reference state) is set at the center of the scene image Ps, the inclination angle θ is The distance from the center on the scene image Ps in consideration of the angle of view, in other words, the interval (number of pixels) from the center position (pixels corresponding thereto) on the image sensor 14b of the imaging unit 14 in consideration of the angle of view. It can be converted. For this reason, when the detection signal is input from the inclination sensor 15, the control unit 16 determines the inclination state (inclination angle θ and the inclination direction) of the vertical indicator 10 (the photographing optical axis OA) from the detection signal, A position displaced from the center position to the side opposite to the tilt direction at an interval corresponding to the tilt angle θ is calculated. The calculated position becomes the vertically lower position of the positioning reference part B as seen in the scene image Ps in the vertical indicator 10 in the inclined state, that is, the display position of the vertical position indication symbol 17.

  FIG. 6 is a flowchart illustrating the contents of the vertical position marking control process executed by the control unit 16 according to the first embodiment. Hereinafter, each step of the flowchart of FIG. 6 will be described. This vertical position marking function is started when an operation to execute the vertical position marking is performed in the operation unit 13.

  In step S1, image acquisition by the imaging unit 14 is started, and the process proceeds to step S2.

  In step S2, following the start of acquisition of an image in the imaging unit 14 in step S1, inclination information is acquired from the inclination sensor 15, and the process proceeds to step S3. In this step S2, based on the output signal from the tilt sensor 15, the tilting state (tilt angle θ and its tilt direction) of the vertical indicator 10, that is, the imaging unit 14 (shooting optical axis OA) is determined.

  In step S3, following the acquisition of the tilt information from the tilt sensor 15 in step S2, the display position of the vertical position marking symbol 17 corresponding to the tilt state is calculated, and the process proceeds to step S4. In step S3, as described above, the vertical lower position of the positioning reference part B in the scene image Ps (imaging element 14b) is calculated from the tilted state of the vertical indicator 10 (imaging part 14). The vertically downward position is the display position of the vertical position marking symbol 17 corresponding to the tilt state in the scene image Ps.

  In step S4, following the calculation of the display position of the vertical position marking symbol 17 according to the tilt state in step S3, image data including the vertical position marking symbol 17 is generated, and the process proceeds to step S5. In this step S4, the image data (scene image Ps) of the scene acquired from the output signal from the imaging unit 14 is generated, and the vertical position indication symbol 17 is superimposed on the display position calculated in step S3 in the image data. Image data (scene image Ps on which the vertical position marking symbol 17 is superimposed) is generated.

  In step S5, following the generation of the image data including the vertical position marking symbol 17 in step S4, the spectacle image Ps based on the image data is displayed on the image display screen 12, and the process proceeds to step S6.

  In step S6, following the display of the spectacle image Ps in step S5 on the image display screen 12, it is determined whether or not an end operation has been performed. If Yes, the process proceeds to step S7. If No, the process proceeds to step S1. Return. In step S <b> 6, it is determined from the input signal from the operation unit 13 whether or not an operation for ending the execution of the vertical position marking is performed in the operation unit 13.

  In step S7, following the determination that the termination operation has been performed in step S6, the display of the vertical position sign symbol 17 is terminated, and the vertical position sign control process is terminated. In step S7, not only the display of the vertical position indication symbol 17 but also the display of the spectacle image Ps on the image display screen 12 may be terminated together.

  In the vertical pointing device 10, when the user selects to execute the vertical position marking on the operation unit 13, the process proceeds to step S1, step S2, step S3, step S4, step S5 in the flowchart of FIG. As a result, as shown in FIG. 4, the scene image Ps of the scene acquired by the imaging unit 14 is displayed on the image display screen 12, and a vertical position indication symbol is displayed at a position vertically below the positioning reference part B in the scene image Ps. 17 is displayed. Further, by repeating this operation (step S6 → step S1), the vertical pointing device 10 always displays the vertical position indication symbol 17 at the vertical lower position of the positioning reference portion B in the scene image Ps on the image display screen 12. To do. Here, if the positioning reference part B is at a fixed position when viewed in horizontal coordinates, the spectacle image Ps changes according to the tilting state of the vertical indicator 10, that is, the imaging part 14 (for example, FIG. 4). (See (a) and (b)), the vertical position marking symbol 17 is positioned at a fixed point in the scene where the scene image Ps is projected, and the image follows the movement of the scene image Ps on the image display screen 12. The position on the display screen 12 changes (for example, see arrow A3 in FIG. 4B). For this reason, in the vertical indicator 10, the vertical position of the positioning reference portion B is set to the vertical position on the scene image Ps on the image display screen 12 regardless of the change in the tilt state of the vertical indicator 10, that is, the imaging unit 14. It can be marked with a marking symbol 17. Therefore, in the vertical indicator 10, the flowchart of FIG. 6 superimposes the vertical position indication symbol 17 on the vertically lower position of the positioning reference part B in the spectacle image Ps in cooperation with the imaging unit 14 and the inclination sensor 15. Thus, it becomes a vertical position indicating means for displaying on the image display screen 12.

  As described above, in the vertical pointing device 10 according to the first embodiment, the scene image Ps acquired by the imaging unit 14 is displayed, and the vertical position indication symbol 17 is always displayed vertically below the positioning reference unit B in the scene image Ps. The images can be displayed on the image display screen 12 in a superimposed manner. For this reason, the user can easily specify the vertically lower position of the positioning reference portion B in the vertical indicator 10 by looking at the image display screen 12.

  Further, the vertical indicator 10 calculates the vertically lower position of the positioning reference part B in the scene image Ps based on the tilt state of the vertical indicator 10, that is, the imaging unit 14 from the inclination sensor 15, and based on the calculation. Since the indication position is indicated by displaying the vertical position indication symbol 17 on the spectacle image Ps, the indication position can be immediately determined without performing the confirmation of the vertical state using the bubble tube, And the indication position can be determined appropriately. Therefore, the user can immediately and appropriately specify the vertical lower position of the positioning reference portion B in the vertical indicator 10 by looking at the image display screen 12.

  Further, in the vertical indicator 10, even when the vertical indicator 10, that is, the positioning reference part B is moved, in the scene image Ps of the image display screen 12, the vertically pointing reference part B is always moved vertically below. The vertical position marking symbol 17 can be displayed overlapping the position. For this reason, the user can specify the vertical downward position of the arbitrary point by positioning the positioning reference part B at an arbitrary point.

  In the vertical indicator 10, if the positioning reference part B is kept at a fixed position when viewed in horizontal coordinates, the image display screen is not affected by the change in the tilt state of the vertical indicator 10, that is, the imaging unit 14. 12, the vertical position marking symbol 17 can be displayed at a fixed point in the scene where the scene image Ps is projected. For this reason, after the user specifies the vertical lower position of the positioning reference part B by looking at the image display screen 12, for example, the vertical indicator is bent by bending the marking such as pile driving at the specific position. 10 (imaging unit 14), even if the inclination state is changed or the pole is removed from the measurement point, the vertical position of the positioning reference unit B can be easily specified by looking at the image display screen 12. .

  The vertical pointing device 10 can display the scene image Ps and the vertical position marking symbol 17 on the image display screen 12 in real time while the vertical position marking function is being executed. For this reason, when the user moves the position while viewing the image display screen 12 to position the positioning reference portion B at an arbitrary point (arbitrary horizontal coordinate position), the user can easily make fine adjustments to the arbitrary point. It is possible to make it more appropriate to specify the vertical downward position of the arbitrary point.

  In the vertical pointing device 10, a scene on the extension line in the directly facing direction to the image display screen 12 viewed from the user side can be acquired by the imaging unit 14 and displayed on the image display screen 12 as a scene image Ps. The vertical position marking symbol 17 can be superimposed on the scene image Ps. For this reason, the user can easily grasp the specific position in the actual scene from the position specified by the vertical position marking symbol 17 displayed in the scene image Ps on the image display screen 12.

  Therefore, in the vertical indicator 10 according to the present invention, it is possible to appropriately and easily grasp the vertical downward position of the predetermined horizontal coordinate position in the space.

  In the first embodiment, the flowchart of FIG. 6 is executed as the vertical position indication control process. However, the scene image Ps of the scene acquired by the imaging unit 14 is displayed on the image display screen 12, and The processing contents of each step (step S1, step S2, step S3, step S4, step S5) are shown so that the vertical position marking symbol 17 can be displayed at a position below the positioning reference part B in the scene image Ps. As long as it is executed, the order of each step (contents of the process) may be changed as appropriate, and is not limited to the first embodiment.

  Next, a vertical indicator 10A according to Embodiment 2 of the present invention will be described with reference to FIGS. The second embodiment is an example in which position information acquisition means is further mounted in the vertical indicator 10 of the first embodiment. Since the basic configuration of the vertical indicator 10A according to the second embodiment is the same as that of the vertical indicator 10 according to the first embodiment, the same reference numerals are given to portions having the same configuration, and a detailed description thereof will be given. Omitted.

  In the vertical indicator 10A according to the second embodiment, as shown in FIGS. 7 and 8, in addition to the configuration of the vertical indicator 10, a collimation target unit 21, a communication unit 22, and an orientation sensor 23 are provided.

  The collimation target unit 21 constitutes a collimation target for measuring a three-dimensional position by the surveying device 50 (see FIG. 9). In the second embodiment, as shown in FIG. 9, the surveying instrument 50 is a total station, which irradiates a pulse laser beam toward a measurement point, receives pulse reflected light from the measurement point, and measures each pulse. It is possible to perform distance measurement (light wave distance measurement), average distance measurement results, and perform distance measurement with high accuracy. The surveying device 50 can detect (measure) the horizontal angle of the collimation direction, which is the irradiation direction of the pulse laser beam, and can detect (measure) the vertical angle of the collimation direction. it can. The collimation target unit 21 is configured to reflect the pulse laser beam from the surveying device 50 toward the surveying device 50 by being installed at the measurement point. And is fixed to the housing 11. For this reason, the surveying instrument 50 can measure the three-dimensional position of the reference position 21a (see FIG. 11) in the collimation target unit 21, and based on the irradiation angle of the pulse laser beam, Regardless of the height position, the horizontal coordinate position of the reference position 21a (collimation target portion 21) can be measured. In addition, although not shown, the surveying device 50 is provided with a communication unit that enables data communication with the communication unit 22.

  The communication unit 22 enables data exchange between the control unit (not shown) of the surveying device 50 and the control unit 16 via the communication unit (not shown) of the surveying device 50. In the second embodiment, the communication unit 22 is capable of wireless communication. At least the horizontal coordinate position data of the reference position 21a (see FIG. 11) of the collimation target unit 21 measured by the surveying device 50 is used for the surveying. It is possible for the control unit 16 to acquire from the device 50 (its control means).

  The direction sensor 23 detects the direction indicated by the reference line of the vertical indicator 10A (housing 11). In the first embodiment, a line segment (see FIG. 11) that includes a geomagnetic sensor capable of measuring an azimuth based on geomagnetism and connects the reference position 21a of the collimation target unit 21 and the positioning reference unit B of the imaging unit 14 is used. It is set as a reference line. For this reason, the azimuth sensor 23 can detect the positional relationship between the reference position 21a fixed to the casing 11 and the positioning reference part B, that is, the displacement direction of the positioning reference part B viewed from the reference position 21a. it can. The direction sensor 23 may be composed of other sensors as long as it detects the direction indicated by the reference line of the vertical indicator 10A (housing 11), and is not limited to the first embodiment. . The direction sensor 23 outputs a detection signal to the control unit 16.

  In the vertical indicator 10A of the second embodiment, the control unit 16 can perform control processing for the vertical position information display function. As shown in FIG. 10, when the vertical position indication symbol 17 is displayed on the image display screen 12 so as to overlap the scene image Ps acquired by the imaging unit 14 by the vertical position indication function, The vertical position information 25 of the vertical position marking symbol 17 is displayed on the image display screen 12. This vertical position information 25 indicates the horizontal coordinate position of the vertically lower position of the positioning reference part B of the imaging unit 14, and is expressed by the x coordinate and the y coordinate in the second embodiment. The vertical position information 25 is generated based on the horizontal coordinate position information of the reference position 21 a of the collimation target unit 21 obtained by the surveying device 50 obtained through the communication unit 22. Below, the production | generation of the vertical position information 25 is demonstrated using FIG.

  In the vertical indicator 10A, the measurement result by the surveying device 50 is the horizontal coordinate position information of the reference position 21a of the collimation target unit 21, while the vertical position indication symbol 17 to be displayed on the image display screen 12 is the position in the scene image Ps. Since the position is the vertically lower position of the positioning reference part B, as shown in FIG. 11, the amount of positional deviation between the reference position 21a and the positioning reference part B becomes a problem when viewed in horizontal coordinates. For this reason, the control unit 16 corrects the horizontal coordinate position information of the reference position 21a based on the positional relationship between the reference position 21a and the positioning reference part B, thereby positioning the positioning reference part B, that is, the vertical position marking symbol 17. The horizontal coordinate position information of the position indicated by is generated.

  First, since the collimation target unit 21 and the imaging unit 14 are fixed to the casing 11, the interval between the reference position 21a and the positioning reference part B can be set in advance and changes. There is nothing. This interval is preset and stored in the storage unit 16a.

  Next, since the horizontal coordinate position is calculated, the positional relationship of the positioning reference part B with respect to the reference position 21a becomes a problem. For this reason, the control unit 16 receives the detection signal from the tilt sensor 15, thereby determining the tilt state from the reference state of the vertical indicator 10 </ b> A (housing 11) and the detection signal from the direction sensor 23. Is input, the positional relationship of the positioning reference part B with respect to the reference position 21a (the orientation of the positioning reference part B viewed from the reference position 21a and the distance between the reference position 21a and the positioning reference part B (spatial coordinates) The position of the positioning reference part B as viewed from the reference position 21a is accurately determined. Based on the positional relationship between the reference position 21a and the positioning reference part B, the control unit 16 calculates a positional deviation amount (offset amount) between the reference position 21a and the positioning reference part B viewed in horizontal coordinates. In the control unit 16, the positional deviation amount (offset amount) viewed in the horizontal coordinates is used as a correction value to the horizontal coordinate position information of the reference position 21a, thereby indicating by the positioning reference unit B, that is, the vertical position indication symbol 17. The horizontal coordinate position information of the indicated position is generated. The control unit 16 generates vertical position information 25 based on the horizontal coordinate position information.

  FIG. 12 is a flowchart illustrating the contents of the vertical position information display control process executed by the control unit 16 according to the second embodiment. Hereinafter, each step of the flowchart of FIG. 12 will be described. This vertical position information display function is started when the operation unit 13 performs an operation to execute vertical position information display. In this vertical position information display, the collimation target unit 21 (reference position 21a) is directed toward the surveying instrument 50 so that the surveying instrument 50 can perform three-dimensional position measurement.

  In step S11, the image acquisition unit 14 starts to acquire an image, and the process proceeds to step S12.

  In step S12, following the start of image acquisition by the imaging unit 14 in step S11, inclination information is acquired from the inclination sensor 15, and the process proceeds to step S13. In step S12, based on the output signal from the tilt sensor 15, the tilting state (tilt angle θ and tilt direction thereof) of the vertical indicator 10A, that is, the imaging unit 14 (shooting optical axis OA) is determined.

  In step S13, following the acquisition of the tilt information from the tilt sensor 15 in step S12, the display position of the vertical position marking symbol 17 corresponding to the tilt state is calculated, and the process proceeds to step S14. In step S13, as described above, the vertical lower position of the positioning reference part B in the scene image Ps (imaging device 14b) is calculated from the tilt state of the vertical indicator 10A (imaging part 14). The vertically downward position is the display position of the vertical position marking symbol 17 corresponding to the tilt state in the scene image Ps.

  In step S14, following the calculation of the display position of the vertical position marking symbol 17 according to the tilt state in step S13, image data including the vertical position marking symbol 17 is generated, and the process proceeds to step S15. In this step S14, the image data (scene image Ps) of the scene acquired from the output signal from the imaging unit 14 is generated, and the vertical position indication symbol 17 is superimposed on the display position calculated in step S3 in the image data. Image data (scene image Ps on which the vertical position marking symbol 17 is superimposed) is generated.

  In step S15, following the generation of the image data including the vertical position marking symbol 17 in step S14, the horizontal coordinate position information is acquired via the communication unit 22, and the process proceeds to step S16. In this step S15, horizontal coordinate position information of the reference position 21a of the collimation target unit 21 measured by the surveying device 50 is acquired by wireless communication with the surveying device 50 (its communication means) via the communication unit 22.

  In step S16, following the acquisition of the horizontal coordinate position information via the communication unit 22 in step S15, the azimuth information is acquired from the azimuth sensor 23, and the process proceeds to step S17. In step S16, the direction of the positioning reference portion B with respect to the reference position 21a is determined based on the output signal from the direction sensor 23.

  In step S17, following the acquisition of the azimuth information from the azimuth sensor 23 in step S16, the vertical position information 25 is generated, and the process proceeds to step S18. In this step S17, the reference position 21a and the positioning reference are determined from the direction of the positioning reference part B with respect to the reference position 21a, the tilted state of the vertical pointing device 10A, and the interval between the reference position 21a and the positioning reference part B. The positional relationship with the part B is determined, and a correction value to the horizontal coordinate position information of the reference position 21a is calculated from the positional relationship. Thereafter, using this correction value, horizontal coordinate position information of the position indicated by the positioning reference portion B, that is, the vertical position marking symbol 17 is generated from the horizontal coordinate position information of the reference position 21a. Thereafter, vertical position information 25 is generated based on the horizontal coordinate position information, and image data (vertical position indication) is displayed by superimposing the vertical position information 25 on the image data including the vertical position indication symbol 17 generated in step S14. A scene image Ps) on which the symbol 17 and the vertical position information 25 are superimposed is generated.

  In step S18, following the generation of the vertical position information 25 in step S17, the spectacle image Ps based on the image data generated in step S17 is displayed on the image display screen 12, and the process proceeds to step S19. As a result, the image display screen 12 displays the spectacle image Ps on which the vertical position marking symbol 17 and the vertical position information 25 are superimposed.

  In step S19, following the display of the image display screen 12 in step S18, it is determined whether or not an end operation has been performed. If Yes, the process proceeds to step S20. If No, the process returns to step S11. In step S <b> 19, it is determined from the input signal from the operation unit 13 whether or not the operation unit 13 has performed an operation for ending the execution of the vertical position information display.

  In step S20, following the determination that the end operation has been performed in step S19, the display of the vertical position indication symbol 17 and the vertical position information 25 is ended, and the vertical position information display control process is ended. In this step S20, not only the display of the vertical position indication symbol 17 and the vertical position information 25 but also the display of the spectacle image Ps on the image display screen 12 may be terminated.

  In the vertical pointing device 10A, when the user selects to display the vertical position information on the operation unit 13, in the flowchart of FIG. 12, step S11 → step S12 → step S13 → step S14 → step S15 → step S16. By proceeding from step S17 to step S18, as shown in FIG. 10, the scene image Ps of the scene acquired by the imaging unit 14 is displayed on the image display screen 12, and the positioning reference unit in the scene image Ps is displayed. A vertical position indication symbol 17 is displayed at a vertically lower position of B, and vertical position information 25 indicating the horizontal coordinates of the vertical position indication symbol 17 is displayed. In the vertical pointing device 10A, by repeating this operation (step S19 → step S11), the vertical position indication symbol 17 is always displayed on the image display screen 12 at a position vertically below the positioning reference portion B in the scene image Ps. In addition, the vertical position information 25 is displayed. From this, in the vertical indicator 10A, the flowchart of FIG. 12 corresponds to the positioning reference unit B in the scene image Ps in cooperation with the imaging unit 14, the inclination sensor 15, the communication unit 22, the direction sensor 23, and the surveying device 50. A vertical position information display means for displaying the vertical position information 25 indicating the horizontal coordinate of the vertical position indication symbol 17 while displaying the vertical position indication symbol 17 on the image display screen 12 while being superimposed on the vertical lower position of the image. For this reason, in the second embodiment, the collimation target unit 21 and the communication unit 22 can acquire horizontal coordinate position information at that time of the reference position 21a of the collimation target unit 21 in cooperation with the surveying device 50. The reference position 21a of the collimation target part 21 functions as an acquisition reference part.

  Since the vertical indicator 10A according to the second embodiment basically has the same configuration as that of the vertical indicator 10 according to the first embodiment, basically the same effects as those of the first embodiment can be obtained.

  In addition, in the vertical pointing device 10A of the second embodiment, the vertical position information 25 indicating the horizontal coordinate of the vertical position marking symbol 17 displayed in an overlapping manner with the vertically lower position of the positioning reference portion B in the scene image Ps is displayed as an image. It can be displayed on the screen 12. That is, in the vertical pointing device 10A, in addition to displaying the vertical lower position (vertical position marking symbol 17) of the positioning reference part B on the image display screen 12, the vertical position marking symbol 17 based on the measurement of the surveying device 50 is displayed. The horizontal coordinates can be displayed on the image display screen 12. For this reason, the user can set the positioning reference part B to an arbitrary horizontal coordinate position based on the measurement of the surveying instrument 50, and can specify the vertical downward position.

  Further, in the vertical indicator 10A, while the vertical position information display function is being executed, the spectacle image Ps, the vertical position indication symbol 17, and the vertical position information 25 can be displayed on the image display screen 12 in real time. Therefore, the user can easily perform fine adjustment to an arbitrary horizontal coordinate position based on the measurement of the surveying instrument 50 by moving while viewing the image display screen 12. That is, since the location indicated by the vertical position indication symbol 17 in the scene image Ps is the arbitrary horizontal coordinate position, the user can move the vertical position information 25 to the position where the display of the vertical position information 25 is the arbitrary horizontal coordinate. The arbitrary horizontal coordinate position in the actual scene can be easily specified simply by moving the pointing device 10 (positioning reference part B). This can facilitate the specification of a measuring point in an actual scene, particularly in a measuring operation, and can facilitate marking such as stakeout.

  Therefore, in the vertical pointing device 10A according to the present invention, it is possible to appropriately and easily grasp the vertical downward position of the predetermined horizontal coordinate position in the space.

  In the second embodiment, the flowchart of FIG. 12 is executed as the vertical position information display control process. However, while displaying the scene image Ps of the scene acquired by the imaging unit 14 on the image display screen 12, Each step (step S11, step S12, step S13, step S14, step S15, step S16, step S11, step S11, step S16, step S16, step S16, step S11, step S16, step S16, step S16, step S16, step S16) As long as the processing content of step S17 and step S18) is executed, the order of each step (processing content) may be appropriately changed, and is not limited to the second embodiment.

  In the second embodiment, the surveying device 50 is used as a part of the position information acquiring unit. However, the position information acquiring unit is capable of acquiring the current position information of the vertical indicator 10A. It is preferable that it be suitable for surveying (having an analysis degree required for surveying), and is not limited to the second embodiment. Here, conforming to surveying means that the degree of analysis is such that the amount of positional deviation between the reference position 21a and the positioning reference part B becomes a problem.

  Next, a vertical indicator 10B according to Example 3 of the present invention will be described with reference to FIG. The third embodiment is an example in which the configuration of the position information acquisition unit is different in the vertical indicator 10A of the second embodiment. Since the basic configuration of the vertical indicator 10B according to the third embodiment is the same as that of the vertical indicator 10A according to the second embodiment described above, the same reference numerals are given to portions having the same configuration, and the detailed description thereof will be described. Omitted.

  In the vertical pointing device 10B according to the third embodiment, as shown in FIG. 13, a positioning terminal unit 24 is provided as a position information acquisition unit instead of the collimation target unit 21 and the communication unit 22.

  The positioning terminal unit 24 is a positioning system using GNSS (Global Navigation Satellite System) and a receiving terminal used therefor. In the third embodiment, the GPS ( It is set as the structure which measures using a global positioning system (Global Positioning System). The positioning terminal unit 24 includes a GPS signal receiving antenna 24a and a GPS signal receiving unit 24b. In the positioning terminal unit 24, the GPS signal received by the GPS signal receiving antenna 24a is input to the GPS signal receiving unit 24b as a GPS signal, and the GPS signal receiving unit 24b performs positioning based on the GPS signal to obtain three-dimensional position information. Is generated. This three-dimensional position information is output to the control unit 16. For this reason, in the positioning terminal unit 24, the GPS signal receiving antenna 24a that receives a GPS signal functions as an acquisition reference unit.

  In the vertical pointing device 10B of the third embodiment, the acquisition reference position is changed from the reference position 21a of the collimation target unit 21 to the GPS signal receiving antenna 24a of the positioning terminal unit 24, and the horizontal coordinate position thereof uses the surveying device 50. The vertical position information display similar to that of the vertical indicator 10A of the second embodiment can be executed except that the measurement is changed to the positioning using the GPS function. Therefore, in the vertical pointing device 10B of the third embodiment, when the vertical position information display is executed, the GPS signal receiving antenna 24a of the positioning terminal unit 24 receives the GPS signal so as to enable the positioning using the GPS function. It must be possible.

  Since the vertical indicator 10B according to the third embodiment basically has the same configuration as the vertical indicator 10A according to the second embodiment, the same effects as those of the first embodiment can be basically obtained.

  In addition, in the vertical pointing device 10B of the third embodiment, without using the surveying device 50, the vertical position indicating symbol 17 displayed alone and superimposed on the vertical lower position of the positioning reference part B in the scene image Ps and its The vertical position information 25 indicating the horizontal coordinates can be displayed on the image display screen 12. For this reason, the user can specify an arbitrary horizontal coordinate position more easily.

  Therefore, in the vertical indicator 10B according to the present invention, it is possible to appropriately and easily grasp the vertical downward position of the predetermined horizontal coordinate position in the space.

  In the third embodiment, the positioning terminal unit 24 is used as a part of the position information acquisition unit. However, the position information acquisition unit is capable of acquiring the current position information of the vertical pointing device 10B. What is necessary is just to be suitable for surveying (having the degree of analysis required in surveying), and is not limited to the third embodiment.

  Next, a vertical indicator 10C according to Embodiment 4 of the present invention will be described with reference to FIGS. The fourth embodiment is an example in which a target position guidance indication function is added to the vertical position information display function in the vertical indicator 10A of the second embodiment. Since the basic configuration of the vertical indicator 10C according to the fourth embodiment is the same as that of the vertical indicator 10A according to the second embodiment described above, the same reference numerals are given to portions having the same configuration, and detailed description thereof will be given. Omitted.

  In the vertical pointing device 10C according to the fourth embodiment, the control unit 16 can perform control processing for the target position guide marking function. As shown in FIG. 14, this target position guidance indication function displays the vertical position indication symbol 17 and the vertical position information 25 on the image display screen 12 so as to overlap the scene image Ps acquired by the imaging unit 14 by the vertical position information display function. In this case, guide sign information 26 from the vertical position sign symbol 17 to the target position is displayed on the image display screen 12. This target position is an arbitrary horizontal coordinate position and indicates, for example, a position set as a measuring point. The horizontal coordinate position information of the target position may be stored (registered) in advance in the storage unit 16a (see FIG. 8) of the control unit 16 of the vertical indicator 10C, or the storage unit of the surveying device 50 (see FIG. 9). May be stored (registered) in advance.

  The guide sign information 26 makes it easy to set the vertical position sign symbol 17 as a target position with respect to the vertical position sign symbol 17 in the scene image Ps. The third embodiment includes a direction sign 26a indicating the displacement direction to the target position with reference to the vertical position sign symbol 17, and an interval sign 26b indicating the distance from the vertical position sign symbol 17 to the target position. The guide sign information 26 is generated based on the horizontal coordinate position information of the reference position 21 a of the collimation target unit 21 obtained by the surveying device 50 obtained through the communication unit 22. Hereinafter, the generation of the guidance sign information 26 will be described.

  In the vertical indicator 10C, similarly to the vertical indicator 10A, the control unit 16 determines the horizontal coordinate position of the position indicated by the positioning reference part B, that is, the vertical position indication symbol 17, from the horizontal coordinate position information of the reference position 21a. Generate information. Thereafter, the control unit 16 determines the positioning reference based on the horizontal coordinate position information, the positional relationship of the positioning reference part B viewed from the reference position 21a, and the target position information (the horizontal coordinate position of the target position). The direction from the part B (the position indicated by the vertical position marking symbol 17) to the target position is calculated. Thereby, it is possible to display the direction sign 26a as the guide sign information 26 in the spectacle image Ps. Further, the control unit 16 calculates the distance from the vertical position marking symbol 17 to the target position based on the generated horizontal coordinate position information of the positioning reference unit B and the horizontal coordinate position information of the target position. Thereby, it is possible to display the interval sign 26b as the guide sign information 26. The calculation of the direction to the target position in the scene image Ps acquired by the imaging unit 14 and the distance from the vertical position sign symbol 17 to the target position generates the guide sign information 26.

  FIG. 15 is a flowchart illustrating the contents of control processing to which a target position guidance indication function executed by the control unit 16 according to the fourth embodiment is added. Hereinafter, each step of the flowchart of FIG. 15 will be described. This target position guide indication function is started when an operation for executing the target position guide indication is performed in the operation unit 13.

  In step S31, image acquisition by the imaging unit 14 is started, and the process proceeds to step S32.

  In step S32, following the start of image acquisition by the imaging unit 14 in step S31, inclination information is acquired from the inclination sensor 15, and the process proceeds to step S33. In step S32, based on the output signal from the tilt sensor 15, the tilting state (tilt angle θ and tilt direction thereof) of the vertical indicator 10C, that is, the imaging unit 14 (shooting optical axis OA) is determined.

  In step S33, following the acquisition of the tilt information from the tilt sensor 15 in step S32, the display position of the vertical position marking symbol 17 corresponding to the tilt state is calculated, and the process proceeds to step S34. In step S33, as described above, the vertical lower position of the positioning reference part B in the scene image Ps (imaging device 14b) is calculated from the tilted state of the vertical pointing device 10C (imaging part 14). The vertically downward position is the display position of the vertical position marking symbol 17 corresponding to the tilt state in the scene image Ps.

  In step S34, following the calculation of the display position of the vertical position marking symbol 17 according to the tilt state in step S33, image data including the vertical position marking symbol 17 is generated, and the process proceeds to step S35. In this step S34, the image data (scene image Ps) of the scene acquired from the output signal from the image pickup unit 14 is generated, and the vertical position indication symbol 17 is superimposed and displayed on the display position calculated in step S33 in the image data. Image data (scene image Ps on which the vertical position marking symbol 17 is superimposed) is generated.

  In step S35, following the generation of the image data including the vertical position marking symbol 17 in step S34, the horizontal coordinate position information is acquired via the communication unit 22, and the process proceeds to step S36. In this step S35, the horizontal coordinate position information of the reference position 21a of the collimation target unit 21 measured by the surveying device 50 is acquired by wireless communication with the surveying device 50 (its communication means) via the communication unit 22.

  In step S36, following the acquisition of the horizontal coordinate position information via the communication unit 22 in step S35, the azimuth information is acquired from the azimuth sensor 23, and the process proceeds to step S37. In step S36, the direction of the positioning reference portion B with respect to the reference position 21a is determined based on the output signal from the direction sensor 23.

  In step S37, following the acquisition of the direction information from the direction sensor 23 in step S36, the vertical position information 25 is generated, and the process proceeds to step S38. In this step S37, the reference position 21a and the positioning reference part B are determined from the direction of the positioning reference part B with respect to the reference position 21a, the inclination state of the vertical pointing device 10C, and the interval between the reference position 21a and the positioning reference part B. Is calculated, and a correction value to the horizontal coordinate position information of the reference position 21a is calculated from the positional relationship. Thereafter, using this correction value, horizontal coordinate position information of the position indicated by the positioning reference portion B, that is, the vertical position marking symbol 17 is generated from the horizontal coordinate position information of the reference position 21a. Thereafter, vertical position information 25 is generated based on the horizontal coordinate position information, and image data (vertical position indication) is displayed by superimposing the vertical position information 25 on the image data including the vertical position indication symbol 17 generated in step S34. A scene image Ps) on which the symbol 17 and the vertical position information 25 are superimposed is generated.

  In step S38, following the generation of the horizontal coordinate position information of the vertical position marking symbol 17 in step S37, the guide marking information 26 is generated, and the process proceeds to step S39.
