Furthermore, the illuminance detection data detected by the illuminance sensor 170 is transmitted from the wireless communication unit 200 to an external personal computer or the like.

  Next, the laser measuring apparatus 10 in which the intelligent target 100 according to the present invention is used will be described. FIG. 4 is a diagram illustrating an example of a schematic configuration of the laser measuring device 10. As such a laser measuring device 10, for example, 3D Disto (registered trademark) manufactured by Leica can be used.

  The laser measuring device 10 has a base part 11 and a turning part 13 that turns around the base part 11. The rotation axis of the rotation unit 13 is indicated by X-X ′ in the drawing. The rotation angle of the rotation unit 13 is measured as a horizontal angle θ. Further, when the laser measuring device 10 receives the control command so that the horizontal angle is θ, the laser measuring device 10 can operate the rotating unit 13 as such.

  The rotating unit 13 of the laser measuring device 10 has two standing parts 15, and has a head part 20 that rotates between these standing parts 15. The rotation axis of the head unit 20 is indicated by Y-Y 'in the drawing. The rotation angle of the head unit 20 is measured as a vertical angle φ. Further, when the laser measuring device 10 receives a control command so that the vertical angle is φ, the laser measuring device 10 can operate the head unit 20 as such.

  The head unit 20 is provided with a laser exit / incident unit 23. In the laser measuring device 10, the laser emission / incident unit 23 emits laser light. The laser beam is reflected by the object and incident again by the laser exit / incident unit 23, so that the laser measuring apparatus 10 can measure the distance r to the object.

  The head unit 20 is provided with an image pickup lens opening 22 adjacent to the laser light incident / incident unit 23. With this image pickup lens opening 22, the laser measuring device 10 can pick up an image in a direction in which the laser emission / incident unit 23 emits laser light. The imaging of the image by the laser measuring device 10 is assumed to be such that a plurality of image data can be acquired in one second. Moreover, it is preferable that the image pickup function in the laser measuring apparatus 10 can perform image enlargement by optical zoom.

  The laser measurement device 10 includes wireless communication means (not shown), and can transmit measurement data to a personal computer, for example, or receive a control command from the personal computer. .

  By the wireless communication means as described above, for example, data related to (r, θ, φ) of the object measured by the laser measuring device 10 can be transmitted to the personal computer, or commanded from the personal computer. It is possible to irradiate a laser beam to the position.

  The wireless communication means of the laser measuring device 10 can transmit the captured image data acquired by the image capturing lens opening 22 to a personal computer or the like.

  Next, measurement examples using the laser measuring apparatus 10 as described above and the intelligent target 100 according to the present invention as the target will be described. FIG. 5 is a diagram for explaining an example of measurement using the intelligent target 100 according to the present invention.

  The intelligent target 100 according to the present invention can communicate with the personal computer 50 wirelessly, receive control commands from the personal computer 50, and transmit detection data to the personal computer 50. It has become.

  Similarly, the laser measuring device 10 can also communicate with the personal computer 50 wirelessly, receive control commands from the personal computer 50, and transmit detection data to the personal computer 50. It has become.

  The personal computer 50 includes an arithmetic unit such as a CPU (Central Processing Unit), a storage unit such as a RAM (Random Access Memory), a ROM (Read Only Memory), and an HDD (Hard Disk Drive), an input / output such as a display and a keyboard. A general component having a communication unit and a communication unit can be used. In the measurement example by the intelligent target 100 according to the present embodiment, the personal computer 50 is used as the information processing apparatus. However, an information processing apparatus such as a tablet terminal or a smartphone may be used.

  In the measurement example of FIG. 5, it is assumed that two laser measurement devices, the laser measurement device 10 and the laser measurement device 10 ′, are used. In any of the laser measuring devices, the coordinates of their installation positions are unknown at the initial stage.

  Therefore, the intelligent target 100 is installed at the first known point, and the first coordinate data of the first known point is acquired by the laser measuring device 10. Next, the intelligent target 100 is installed at the second known point, and the second coordinate data of the second known point is acquired by the laser measuring device 10. And the position coordinate in which the laser measuring device 10 is installed is calculated | required from 1st coordinate data and 2nd coordinate data. The position coordinates of the other laser measuring device 10 'are also obtained by the same procedure.

  From the laser measuring device 10 and the laser measuring device 10 ′ whose installation coordinates are clarified, a laser beam is irradiated to a design position such as a mounting position of a building member. Thereby, positioning of the attachment position of a building member can be performed.

  In addition, although the laser beam irradiation to the design position can be performed with only one laser measuring apparatus 10, the certainty of positioning can be further improved by performing the two lasers simultaneously.

  The basic “sighting process” in performing the series of measurement operations as described above will be described. This “sighting process” is a process for irradiating the aiming position of the intelligent target 100 with the laser beam of the laser measuring device 10.

  In this measurement example, as shown in FIG. 5, when the intelligent target 100 according to the present invention is installed at the first known point and the laser measuring device 10 is installed at a point where the position coordinates are unknown, the laser measuring device 10 A process for irradiating the aiming position of the intelligent target 100 with laser light is executed.

  FIG. 6 is a flowchart of the aiming process using the intelligent target 100 according to the present invention. In the flowchart of FIG. 6, the processing flow of each of the personal computer 50, the laser measuring device 10, and the intelligent target 100 is shown.

  In FIG. 6, when the aiming process is started, the personal computer 50 transmits a blink command to the intelligent target 100 in step S <b> 101.

  When the intelligent target 100 receives the blink command data in step S301, subsequently, in step S302, the intelligent target 100 starts blinking the unit illumination 141 of the illumination unit 140. In the blinking of the illumination unit 140, all the unit lights 141 are turned on simultaneously, and all the unit lights 141 are turned off simultaneously.

  Subsequently, the personal computer 50 transmits an image capturing command to the laser measuring device 10 in step S102.

  In response to this, when the laser measuring device 10 receives the image capturing command data in step S201, in step S202, the laser measuring device 10 performs image capturing using the image capturing function. The image capturing in this step S202 is executed a plurality of times. Therefore, as the image data to be captured, both the image data when the unit illumination 141 in the illumination unit 140 is simultaneously turned on and the image data when the unit illumination 141 in the illumination unit 140 is simultaneously turned off are displayed. Data is acquired.

  In step S <b> 203, the laser measurement device 10 transmits the captured image data to the personal computer 50.

  When the personal computer 50 receives the captured image data from the laser measuring device 10 in step S103, the personal computer 50 transmits a blinking stop command to the intelligent target 100 in step S104.

  When the intelligent target 100 receives the blink stop command data in step S303, subsequently, in step S304, the intelligent target 100 stops blinking of the unit illumination 141 of the illumination unit 140.

  In step S <b> 105, the personal computer 50 performs image processing on the plurality of image data received from the laser measurement device 10. Specifically, the difference between the image data when the unit lighting 141 in the lighting unit 140 is simultaneously turned on and the image data when the unit lighting 141 in the lighting unit 140 is turned off at the same time is obtained. The unit illuminations 141 arranged on the circumference in the data are extracted.

  In the subsequent step S106, the position coordinates of the centers of the unit illuminations 141 arranged on the circumference in the image data are obtained. In the next step S107, center coordinate directing command data is transmitted to the laser measuring device 10 so as to direct the laser beam emitted from the laser measuring device 10 with respect to the position coordinates of the center.

  When the laser measuring device 10 receives the central coordinate directing command data from the personal computer 50 in step S204, in step S205, the direction (aiming direction) is adjusted so that laser light is emitted toward the central coordinate. More specifically, the positions of the rotating unit 13 and the head unit 20 are adjusted to adjust the laser beam emission direction.

  Subsequently, on the personal computer 50 side, in step S108, image data obtained by further magnifying the illumination unit 140 can be processed with reference to the image data, and the laser measuring apparatus 10 has an enlargement capacity by optical zoom. It is determined whether or not.

  If the determination in step S108 is YES, the process proceeds to step S109, and zoom command data is transmitted to the laser measuring device 10.

  On the laser measurement device 10 side, when zoom command data is received from the personal computer 50 in step S206, enlargement zoom is executed in step S207. On the personal computer 50 side, the process returns to step S101 again to obtain zoomed image data of the illumination unit 140. Thus, in the present invention, the adjustment is repeated so that the aiming position is irradiated with laser light with higher accuracy by obtaining image data of the illumination unit 140 that is enlarged as much as possible.

  On the other hand, if the determination in step S108 is NO, no further enlarged image data can be obtained, so the process proceeds to step S110 to execute a measurement position coordinate acquisition processing routine.

  Next, the measurement position coordinate acquisition process as described above will be described. FIG. 7 is a flowchart of measurement position coordinate acquisition processing using the intelligent target 100 according to the present invention. In the flowchart of FIG. 7, the processing flow of each of the personal computer 50, the laser measuring device 10, and the intelligent target 100 is shown.

  In FIG. 7, when the measurement position coordinate acquisition process is started, the personal computer 50 transmits a laser irradiation command to the laser measurement device 10 in step S <b> 401.

  When the laser measuring apparatus 10 receives laser irradiation command data from the personal computer 50 in step S501, the laser measuring apparatus 10 proceeds to step S502 and starts laser irradiation.

  Here, the significance of detecting the illuminance by providing the illuminance sensor 170 at the aiming position of the intelligent target 100 will be described. FIG. 8 is a diagram illustrating a situation in which the laser measurement device 10 supplements the reflected image of the illumination unit 140.

  For example, when the intelligent target 100 is used in the vicinity of a glass window or the like, a reflected image of the illumination unit 140 may be formed on the glass window as shown in FIG. At this time, there is a possibility that the personal computer 50 that processes the image data acquired by the laser measuring device 10 may erroneously recognize the reflected image of the illumination unit 140 as the image data of the illumination unit 140 of the intelligent target 100. is there. If measurement proceeds with such misrecognition, an incorrect position coordinate will be acquired.

  Therefore, in the intelligent target 100 according to the present invention, the personal computer 50 misrecognizes the reflected image of the illumination unit 140 as the image data of the illumination unit 140 of the intelligent target 100 and does not acquire an incorrect position coordinate. As a configuration for doing so, an illuminance sensor 170 is provided at the aiming position.

  When the personal computer 50 performs the above-described misrecognition, even if the laser measurement device 10 irradiates the aiming position with the laser light, the illuminance sensor 170 does not detect an illuminance of a predetermined level or more. . Therefore, in the intelligent target 100 according to the present invention, it is determined that the personal computer 50 correctly recognizes the image data of the illumination unit 140 only when a predetermined illuminance is detected from the illuminance sensor 170.

  Now, following step S401, the personal computer 50 transmits an illuminance sensor detection command to the intelligent target 100 in step S402.

  When the intelligent target 100 receives the illuminance sensor detection command data from the personal computer 50 in step S601, the intelligent target 100 proceeds to step S602, detects the illuminance by the illuminance sensor 170, and sends the illuminance detection data to the personal computer 50 in step S603. Send to.

  When the personal computer 50 receives the detection data of the illuminance from the intelligent target 100 in step S403, the personal computer 50 proceeds to step S404 and transmits a laser irradiation stop command to the laser measurement device 10.

  Correspondingly, in the laser measuring device 10, when the laser irradiation stop command data is received in step S503, the process proceeds to step S504, where the laser irradiation is stopped.

  In step S405, the personal computer 50 determines whether the received illuminance detection data is greater than or equal to a predetermined value. When the determination in step S405 is NO, it is assumed that the personal computer 50 may have recognized the reflected image of the illumination unit 140, and the process proceeds to step S406 and is processed as an error.

  On the other hand, if the determination in step S405 is YES, the process proceeds to step S407, and a coordinate measurement command is transmitted to the laser measurement device 10.

  When the laser measurement apparatus 10 receives coordinate measurement command data from the personal computer 50 in step S505, the laser measurement apparatus 10 performs coordinate measurement in step S506, and transmits the measured coordinate data to the personal computer 50 in step S507.

  On the personal computer 50 side, when coordinate data is received in step S408, the process proceeds to step S409, the coordinate data is stored, and the process ends in step S410.

  As described above, the intelligent target 100 according to the present invention includes the illumination unit 14 including the plurality of unit illuminations 141 arranged on the circumference of the first surface 105 of the housing 104, and the unit illumination 141 in the illumination unit 14. A control unit 110 that controls blinking; and a wireless communication unit 200 that transfers data received from the outside to the control unit 110 and transmits data transferred from the control unit 110 to the outside. According to such an intelligent target 100 according to the present invention, it is possible to easily perform the task of finding a target by the laser measuring device 10 and aiming at the site without taking time and effort.

  Next, a procedure for calculating the coordinates of the installation position of the laser measuring device 10 from two known points will be described. FIG. 9 is a flowchart of a procedure for calculating the installation position of the laser measuring device 10.

  In FIG. 9, when the procedure is started in step S700, the process proceeds to step S701, where the intelligent target 100 according to the present invention is installed at the first known point.

  In step S <b> 702, the first coordinate data of the first known point is acquired by the laser measuring device 10, and the first coordinate data is stored in the personal computer 50.

  Then, it progresses to step S703 and the intelligent target 100 which concerns on this invention is installed in a 2nd known point.

  In step S <b> 704, the second coordinate data of the second known point is acquired by the laser measuring device 10, and the second coordinate data is stored in the personal computer 50.

  In step S705, the coordinate data of the installation position of the laser measuring device 10 is calculated from the first coordinate data and the second coordinate data stored in the personal computer 50. A known algorithm can be used for the method of calculating the coordinate data of the installation position of the laser measuring device 10.

  From the laser measuring device 10 and the laser measuring device 10 'whose coordinates of the installation position are known by the procedure as described above, as shown in FIG. Light can be irradiated and positioning can be performed easily.

  Next, another usage pattern of the intelligent target 100 according to the present invention will be described. The intelligent target 100 according to the present invention adopts a highly airtight structure so that it can be used outdoors, and because the power generation panel 205 is used, it is not necessary to replace the battery. Up to. Taking advantage of the characteristics of the intelligent target 100 according to the present invention, the intelligent target 100 according to the present invention can be used for continuous monitoring of a construction object.

  After construction, there is a need to monitor the deviation of the construction after construction because the construction may be displaced from the design due to the influence of wind or earthquake. The intelligent target 100 according to the present invention can meet such needs. This will be described below based on the example shown in FIG.

  FIG. 11 is a diagram for explaining monitoring of a construction using the intelligent target 100 according to the present invention. An intelligent target 100 according to the present invention is attached to an appropriate position of the construction object. Moreover, the laser measuring device 10 is installed in the position which can aim the intelligent target 100 attached to the construction object. A personal computer 50 capable of data communication with the intelligent target 100 and the laser measuring device 10 is also provided.

  FIG. 12 is a flowchart of a procedure for monitoring a construction by the intelligent target 100. When the monitoring procedure using the intelligent target 100 is started in step S800, the intelligent target 100 is attached to the work in the next step S801, for example, as shown in FIG.

  In step S802, the position coordinates of the intelligent target 100 are acquired by the laser measuring device 10, and in step S803, the position coordinates acquired by the laser measuring device 10 are stored in the personal computer 50.

  In step S804, it is determined whether a predetermined time has elapsed. For example, if position coordinates are acquired every 10 minutes, it is determined in this step whether or not 10 minutes have elapsed. If the determination in step S804 is YES, the process returns to step S802 to acquire position coordinates. On the other hand, if the determination in step S804 is no, the process proceeds to step S805 to determine whether or not the monitoring is complete.

  While the determination in step S805 is NO, the process returns to step S804. If the determination in step S805 is YES, the process proceeds to step S806, and the flowchart ends.

  By monitoring the construction as described above using the intelligent target 100 according to the present invention, the personal computer 50 collects log data of the position coordinates of the intelligent target 100 attached to the construction. Thus, it is possible to analyze whether or not the construction has shifted from the design due to the influence of wind or earthquake based on this log data.

  As described above, the intelligent target according to the present invention includes an illumination unit including a plurality of unit illuminations arranged on the circumference on the first surface of the housing, a control unit that controls blinking of the unit illuminations in the illumination unit, and an external And the communication unit that transmits the data transferred from the control unit to the outside while transferring the data received from the control unit, and according to such an intelligent target according to the present invention, In this case, it is possible to easily perform the task of finding a target by using a laser measuring device and adjusting the aim without taking time and effort.
