It is determined whether or not the position of the target held by the person can be measured. For example, when receiving the current position information of the target from the surveying apparatus 10, the current position correction processing unit 74 determines that the target position can be measured by the surveying apparatus 10. If the current position correction processing unit 74 determines that the target position can be measured by the surveying instrument 10, the process proceeds to step S32. When the current position correction processing unit 74 determines that the target position cannot be measured by the surveying instrument 10, the process proceeds to step S35.

A position correction value is calculated. Specifically, the current position correction processing unit 74 calculates a difference value between the survey result (specifically, the current position information of the target) and the current position as a current position correction value.

Next, in step S34, the current position correction processing unit 74 corrects the current position obtained based on the signal received from the GNSS satellite 100 with the current position correction value calculated in step S33. Specifically, the current position correction processing unit 74 adds the current position correction value as an offset value to the current position obtained based on the signal received from the GNSS satellite 100. Then, the current position correction processing unit 74 ends the process shown in FIG.

In step S35, the current position correction processing unit 74 determines whether or not there is a current position correction value previously calculated in the current position correction process. If the current position correction processing unit 74 determines that there is a previously calculated current position correction value, the process proceeds to step S34. If the current position correction processing unit 74 determines that there is no previously calculated current position correction value, the current position obtained based on the signal received from the GNSS satellite 100 cannot be corrected, and the process shown in FIG. 6 ends. To do.

Note that the current position correction processing unit 74 has a difference value between the position of the mobile communication terminal 50 and the current position of the mobile communication terminal 50 when the current position correction value has been calculated previously is larger than a threshold value for difference value determination. If it is determined, the current position correction value is reset. Here, the threshold value for determining the difference value is a value for determining whether or not the mobile communication terminal 50 has moved from an area where the current position correction value can be used. For example, the threshold value for determining the difference value is a value set in advance experimentally, empirically, or theoretically. If the current position correction processing unit 74 determines that the difference value is larger than the difference value determination threshold value, the current position correction value is determined because the mobile communication terminal 50 has moved from an area where the current position correction value can be used. As position correction value is not available,
Reset the current position correction value. When the current position correction value is reset in this way, the current position correction processing unit 74 determines that there is no previously calculated current position correction value in the determination process of step S35.
The processing shown in FIG. 6 is as described above.

Next, the azimuth angle correction process shown in FIG. 7 will be described.
As shown in FIG. 7, first, in step S <b> 51, the azimuth angle correction processing unit 75 determines whether or not an azimuth angle correction instruction is input from the information input unit 51. If the azimuth correction processing unit 75 determines that an azimuth correction instruction has been input from the information input unit 51, the process proceeds to step S52.
If the azimuth angle correction processing unit 75 determines that no azimuth angle correction instruction is input from the information input unit 51, the process proceeds to step S58.

In step S52, the azimuth correction processor 75 issues a request for switching to the correction mode to the surveying device 1.
Send to 0.
Next, in step S53, the azimuth correction processing unit 75 (or the position measurement state determination unit 72) is held by a surveying operator who carries the target (specifically, the portable communication terminal 50) by the surveying device 10. It is determined whether or not the position of the target) can be measured. For example, when the current position information of the target is received from the surveying apparatus 10, the azimuth angle correction processing unit 75 determines that the target position measurement by the surveying apparatus 10 is possible. If the azimuth correction processing unit 75 determines that the target position can be measured by the surveying instrument 10, the process proceeds to step S54. If the current position correction processing unit 74 determines that the target position cannot be measured by the surveying instrument 10, the process proceeds to step S58.

In step S <b> 54, the azimuth angle correction processing unit 75 calculates the azimuth angle that the mobile communication terminal 50 faces based on the survey result transmitted from the surveying apparatus 10. For example, the survey result of the surveying device 10 is the azimuth angle of the portable communication terminal 50 (specifically, the target held by the surveying operator carrying the portable communication terminal 50) viewed from the surveying device 10 by the surveying device 10. If it is information, the azimuth angle correction processing unit 75, based on the information of the azimuth angle, the surveying device 10 viewed from the mobile communication terminal 50.
The azimuth angle of is calculated. In addition, the survey result of the surveying device 10 is the position of the surveying device 10 (instrument point).
And the position of the mobile communication terminal 50 (specifically, the current position of the target held by the surveying operator carrying the mobile communication terminal 50), the azimuth angle correction processing unit 75 stores information on these positions. Based on the above, the azimuth angle of the surveying instrument 10 viewed from the mobile communication terminal 50 is calculated.

Next, in step S <b> 55, the azimuth angle correction processing unit 75 detects the azimuth angle of the surveying apparatus 10 as viewed from the mobile communication terminal 50 by the azimuth angle sensor 53. For example, in a state in which the mobile communication terminal 50 is directed to the surveying device 10 (specifically, a state in which the surveying device 10 is captured by the camera 52), the azimuth correction processing unit 75 is based on the detection value of the azimuth angle sensor 53. Detect azimuth.
For example, the mobile communication terminal 50 displays an image (for example, “+
"Aiming mark" is displayed, and the azimuth is detected based on the detection value of the azimuth sensor 53 when the surveying device in the captured image overlaps the displayed image.

Next, in step S56, the azimuth angle correction processing unit 75 performs azimuth based on the azimuth angle calculated in step S54 (ie, the calculated azimuth angle) and the azimuth angle detected in step S55 (ie, the detected azimuth angle). An angle correction value is calculated. Specifically, the azimuth angle correction processing unit 75 calculates a difference value between the calculated azimuth angle and the detected azimuth angle as an azimuth angle correction value.

Next, in step S57, the azimuth angle correction processing unit 75 corrects the detected azimuth angle detected using the azimuth angle sensor 53 with the azimuth angle correction value calculated in step S56. In particular,
The azimuth correction processing unit 75 adds the azimuth correction value as an offset value to the detected azimuth detected using the azimuth sensor 53. Then, the azimuth angle correction processing unit 75 ends the processing shown in FIG.

In step S58, the azimuth angle correction processing unit 75 determines whether or not there is an azimuth angle correction value previously calculated in the azimuth angle correction processing. If the azimuth correction processing unit 75 determines that there is a previously calculated azimuth correction value, the process proceeds to step S57. If the azimuth angle correction processing unit 75 determines that there is no previously calculated azimuth angle correction value, the detected azimuth angle cannot be corrected and the process shown in FIG. 7 ends.

Note that the azimuth angle correction processing unit 75 uses the mobile communication terminal 50 when the azimuth angle correction value has been calculated previously.
If it is determined that the difference value between the current position and the current position of the mobile communication terminal 50 is greater than the difference value determination threshold, the azimuth correction value is reset. Here, the threshold value for difference value determination is a value for determining whether or not the mobile communication terminal 50 has moved from an area where the azimuth angle correction value can be used. For example, the threshold value for determining the difference value is a value set in advance experimentally, empirically, or theoretically. That is, when the current position correction processing unit 74 determines that the difference value is larger than the difference value determination threshold value, the mobile communication terminal 50 has moved from an area where the azimuth correction value can be used. Assuming that the azimuth correction value cannot be used, the azimuth correction is reset. When the azimuth correction value is reset in this way, the azimuth correction processing unit 75 determines that there is no previously calculated azimuth correction value in the determination process of step S58.
The processing shown in FIG. 7 is as described above.

Next, a process for transmitting the current position information of the target performed by the surveying apparatus 10 will be described. FIG. 9 shows a flowchart of an example of the process.
As shown in FIG. 9, first, in step S <b> 71, the surveying apparatus 10 determines whether a request for switching to the surveying mode has been received from the mobile communication terminal 50. When the surveying apparatus 10 determines that the request for switching to the surveying mode has been received from the mobile communication terminal 50, the surveying apparatus 10 proceeds to step S72.

In step S72, the surveying apparatus 10 determines whether or not a target (specifically, a target possessed by a surveying operator carrying the mobile communication terminal 50) has been detected. For example, the surveying apparatus 10 determines that the target has been detected when the azimuth and distance of the target can be measured. When the surveying instrument 10 determines that the target has been detected, step S
Go to 73.

In step S <b> 73, the surveying apparatus 10 transmits the measured current position information of the target to the mobile communication terminal 50.
The processing shown in FIG. 9 is as described above. By the processing shown in FIG.
0 calculates the current position information of the target as needed based on the surveyed result of the detected target, and transmits the calculated current position information of the target to the mobile communication terminal 50 as needed.

(Operation, action, etc.)
Next, an example of a series of operations and their actions in the surveying work support system 1 will be described.
First, an example of the operation at the time of measurement will be described with reference to FIG.

The surveying operator instructs the surveying point for displaying the guidance information on the mobile communication terminal 50 carried by him / her (step S101). Here, the surveying operator carries the target. In response to this instruction, the mobile communication terminal 50 transmits a request for switching to the surveying mode to the surveying apparatus 10 (step S102). Then, the mobile communication terminal 50 displays an image with guidance information (image with simple guidance information) in which guidance information is combined with an image captured by the camera 52 (step S103).
Specifically, the mobile communication terminal 50 specifies the current position of the mobile communication terminal 50 based on the signal received from the GNSS satellite 100 (step S2). Furthermore, the mobile communication terminal 50
Creates an image in which the guidance information is combined with the captured image (that is, the guidance information is combined with the captured image as a virtual object) based on the identified current position (step S3). And
The mobile communication terminal 50 displays the created composite image on the display unit 58 (step S4).
As a result, the surveying operator can move to the surveying point based on the guidance information on the captured image displayed as augmented reality on the display unit 58 (that is, the plane image of the mesh) (step S104). ). At this time, the surveying operator matches the portable communication terminal 50 with the target position as much as possible in order to move to the surveying point with high accuracy.

In conventional technology, an operator operating a surveying instrument cannot measure the azimuth and distance of the target with the surveying instrument (that is, the target is not within the range that the surveying instrument can measure and is directly facing the surveying instrument. Otherwise, the information on the relative positional relationship between the target and the planned installation point cannot be obtained from the surveying device, so the installation operator with the target cannot be guided to the installation point. It was. On the other hand, in this embodiment, since the surveying device 10 cannot measure the azimuth and distance of the target, guidance information to the surveying point is displayed on the mobile communication terminal 50, so that the surveying operator Can move to the survey point based on the guidance information.

In addition, since guidance information is always displayed on the mobile communication terminal 50, an environment in which it is difficult for a surveying operator to transmit information by verbal or cue from a worker who operates the surveying device by referring to the guidance information. You can move to the survey point even below.
In addition, the plane image of the mesh serving as guidance information includes the survey point and the position of the surveying device (that is, the instrument point), and the shape of the plane image of the mesh changes based on the current position of the target (that is, the portable communication terminal 50). Therefore, the surveying operator selects the target (that is, the mobile communication terminal 50) depending on the display mode of the planar image of the mesh on the display unit 58 of the mobile communication terminal 50 (for example, it can be seen as a surface or a simple line). Current location, survey point,
And the relative positional relationship between the surveying devices can be easily grasped.

For example, when the surveying operator moves to the left and approaches the measuring point, the planar image of the mesh, which is the guidance information displayed on the mobile communication terminal 50, is shown in FIGS. 8 (a) and 8 (b). ) And FIG. 8 (
It changes in the order of c). Due to the display mode of the plane image of the mesh that changes in this manner, the surveying operator can easily determine the relative position relationship between the current position of the target (that is, the portable communication terminal 50), the surveying point, and the surveying instrument even during movement. Can grasp. Thereby, for example, the surveying operator can see that the plane side of the plane image of the mesh is displayed on the display unit 58 of the mobile communication terminal 50, and is not facing the surveying device 10. Therefore, the surveying operator moves so that the planar image of the mesh is displayed on one line extending in the vertical direction, so that the surveying apparatus 10
(Ie, the surveying instrument 10 can move to a position where it can be measured with respect to the target).

Then, the guidance information is displayed as an augmented reality on the photographed image, so that the surveying operator can compare the actual surveying work site displayed in the photographed image with the guidance information displayed as the augmented reality. Therefore, it is possible to intuitively grasp the absolute position of the measuring point.
When the surveying operator moves to a position where the surveying apparatus 10 can measure the target (step S105), the surveying apparatus 10 transmits the current position information of the target obtained by the measurement to the mobile communication terminal 50 (step S106). ). Thereby, the mobile communication terminal 5
0 creates an image with guidance information (image with detailed guidance information) in which guidance information is combined with a captured image (step S107). Specifically, the mobile communication terminal 50 specifies the current position of the mobile communication terminal 50 based on the current position information of the target transmitted from the surveying device 10 (
Step S5). Furthermore, the mobile communication terminal 50 uses the camera 5 based on the identified current position.
An image in which the guidance information is combined with the two captured images (that is, the guidance information is combined with the captured image as a virtual object) is created (step S6). Then, the mobile communication terminal 50 displays the created composite image on the display unit 58 (step S7). As a result, the surveying operator moves to the surveying point based on the guidance information on the captured image displayed as augmented reality on the display unit 58 (that is, the mesh plane image) (step S108). At this time, the surveying operator matches the portable communication terminal 50 with the target position as much as possible in order to move to the surveying point with high accuracy.

Here, the current positioning technique using GNSS may involve an error of several meters to several tens of meters. On the other hand, the survey result of the surveying instrument 10 is expected to be obtained with an error accuracy of several millimeters. For this reason, the surveying operator can use the surveying device 10.
After moving to a position where the target can be measured, by moving to the measuring point based on the guidance information displayed on the mobile communication terminal 50, it is possible to move to the measuring point with an error accuracy of several millimeters.

Further, as a form different from the above-described embodiment, it is also conceivable that guidance information is displayed on the mobile communication terminal 50 only when the surveying instrument 10 moves to a position where measurement can be performed with respect to the target. On the other hand, in this embodiment, the surveying operator displays the guidance information on the portable communication terminal 50 before the surveying apparatus 10 moves to a position where the target can be measured as described above, so that the surveying operator can efficiently perform the measurement. You can move to the point.

Next, an example of the operation at the time of correcting the current position will be described with reference to FIG.
When the surveying operator moves to a position where the surveying device 10 can measure the target (step S121), the surveying device 10 transmits the current position information of the target obtained from the surveying result to the mobile communication terminal 50 (step S122). . At this time, the surveying operator matches the portable communication terminal 50 with the target position as much as possible in order to move to the surveying point with high accuracy. Thereby, the current position information of the target from the surveying device 10 is stored in the mobile communication terminal 5.
The current position information is almost equal to zero.

When receiving the current position information of the target, the mobile communication terminal 50 calculates a current position correction value (step S123). Specifically, the mobile communication terminal 50 specifies the current position of the mobile communication terminal 50 based on the signal received from the GNSS satellite 100 (step S32). Then, the mobile communication terminal 50 calculates a current position correction value based on the current position information of the target from the surveying apparatus 10 and the specified current position (Step S33).

Then, the mobile communication terminal 50 corrects the current position obtained based on the signal received from the GNSS satellite 100 based on the calculated current position correction value (step S124).
When the surveying operator moves to a position where the surveying apparatus 10 can measure the target by such correction of the current position, the mobile communication terminal 50 uses the current position information of the target from the surveying apparatus 10 to perform the mobile communication terminal. The current position that can be specified by 50 itself is corrected, and an image with guidance information (image with detailed guidance information) is created based on the corrected current position. Thereby, when the surveying operator moves to a position where the surveying apparatus 10 can measure the target, the planar image of the mesh, which is the guidance information displayed on the mobile communication terminal 50, corresponds to the correction amount of the current position. The position of each of the instrument point (ie, the position of the surveying instrument) and the survey point changes.

Furthermore, after the surveying operator moves to a position where the surveying device 10 can measure the target, even if the surveying operator moves outside the range where the surveying device 10 can measure the target, the mobile communication terminal 50 has already calculated. The current position can be corrected based on the current position correction value (step S35 → step S34). As a result, the mobile communication terminal 50 creates an image with guidance information based on the corrected current position.

In this way, if the surveying operator moves even once to a position where the surveying apparatus 10 can measure the target, then the mobile communication terminal 50 creates an image with guidance information based on the corrected current position. Become.
Here, since the current positioning technique using GNSS may involve an error of several meters to several tens of meters, assuming that the current position obtained by GNSS is not corrected, the guidance information in the image with guidance information There is a possibility that the consistency between the (that is, the planar image of the mesh) and the captured image cannot be maintained. On the other hand, in this embodiment, the mobile communication terminal 50 uses the corrected current position to maintain consistency between the guidance information (that is, the mesh planar image) and the captured image in the image with guidance information. be able to. As a result, the measurement operator can intuitively grasp the absolute position of the measurement point accurately.

Next, an example of the operation at the time of correcting the azimuth will be described with reference to FIG.
The surveying operator instructs the mobile communication terminal 50 carried by him / her to correct the azimuth (step S141). Thereby, the mobile communication terminal 50 issues a request for switching to the correction mode to the surveying device 1.
It transmits to 0 (step S142). When the surveying operator moves to a position where the surveying apparatus 10 can measure the target (step S143), the surveying apparatus 10 transmits the survey result (for example, azimuth angle information) to the mobile communication terminal 50 (step S144). ). When receiving the survey result, the portable communication terminal 50 calculates an azimuth correction value based on the survey result (step S145). That is, for example, the mobile communication terminal 50 calculates the difference value between the azimuth angle obtained as the survey result and the azimuth angle detected by the azimuth angle sensor 53 as the azimuth angle correction value (step S54 to step S56).

Then, the portable communication terminal 50 corrects the detected azimuth angle detected using the azimuth angle sensor 53 with the azimuth angle correction value (step S146).
When the surveying operator moves to a position where the surveying device 10 can measure the target by correcting the azimuth, the mobile communication terminal 50 detects the survey using the survey result from the surveying device 10. The corrected azimuth angle is corrected, and an image with guidance information (an image with detailed guidance information) is created based on the corrected azimuth angle. Furthermore, after the surveying operator moves to a position where the surveying device 10 can measure the target, even if the surveying operator moves outside the range where the surveying device 10 can measure the target, the mobile communication terminal 50 has already calculated. The current position can be corrected based on the azimuth correction value that has been set (step S58 → step S57).
). Accordingly, the mobile communication terminal 50 creates an image with guidance information based on the corrected azimuth angle.

In this way, if the surveying operator moves even once to a position where the surveying apparatus 10 can measure the target, the mobile communication terminal 50 thereafter creates an image with guidance information based on the corrected azimuth angle. Become.
Next, various other processes in the mobile communication terminal 50 will be described using display examples on the display unit 58 of the mobile communication terminal 50.

Here, as a premise, the mobile communication terminal 50 stores a plurality of measuring points in the storage unit 57 as coordinate data files. Moreover, the portable communication terminal 50 and the surveying apparatus 10 share coordinate data by transmitting and receiving coordinate data files via wireless communication.
First, an example of processing for displaying a measuring point of an arbitrary coordinate data file in the mobile communication terminal 50 will be described. FIG. 13 is a diagram showing a display example by the processing. For example, this process is performed by the data management unit 71.
