Summary of the Invention

Problems to be Solved by the Invention

[0005] However, the conventional lighting environment measurement system described above assumes that the mobile body can move to the measurement position, and it was completely unclear how to obtain illuminance measurement results at the measurement position when the mobile body cannot move to that position.

[0006] The present invention has been made in view of these circumstances, and aims to provide a method for obtaining illuminance measurement results, an apparatus and program thereof, and an illuminance measurement system using the apparatus, which can accurately obtain illuminance measurement results at a measurement location under predetermined lighting conditions, even when it is not possible to actually measure illuminance at a measurement location for which illuminance measurement results should be obtained, for reasons such as the mobile body on which the illuminance measurement unit is mounted being unable to move to the measurement location, or for other reasons. [Means for solving the problem]

[0007] To solve the aforementioned problems, the following embodiments are presented. The first embodiment is a method for obtaining illuminance measurement results, which obtains illuminance measurement results at a first three-dimensional position under predetermined lighting conditions, and calculates the illuminance measurement results at the first three-dimensional position under predetermined lighting conditions based on illuminance measured at a second three-dimensional position that differs only in height from the first three-dimensional position under the predetermined lighting conditions.

[0008] According to this first embodiment, the measurement result of the illuminance at the first three-dimensional position under the predetermined lighting conditions is calculated based on the illuminance measured at a second three-dimensional position that differs from the first three-dimensional position only in height under the predetermined lighting conditions. Therefore, even if it is not possible to measure the illuminance at the first three-dimensional position, if the difference in height between the first three-dimensional position and the first three-dimensional position is not so large, the measurement result of the illuminance at the first three-dimensional position under the predetermined lighting conditions can be obtained with good accuracy.

[0009] The second method for obtaining illuminance measurement results is as follows: In the first embodiment, LXth1 is the first illuminance at the first three-dimensional position calculated according to the predetermined lighting conditions, LXth2 is the second illuminance at the second three-dimensional position calculated according to the predetermined lighting conditions, LXm2 is the illuminance measured at the second three-dimensional position, and LXm1 is the measurement result of the illuminance at the first three-dimensional position under the predetermined lighting conditions. LXm1 is calculated according to the formula LXm1 = LXm2·LXth1 / LXth2.

[0010] This second embodiment provides a specific example of the calculation method in the first embodiment. According to this second embodiment, since the ratio LXth1 / LXth2 of LXth1 to LXth2 is used after utilizing LXm2, the measurement result LXm1 of the illuminance at the first three-dimensional position under the predetermined lighting conditions can be obtained with greater accuracy.

[0011] The third embodiment of the method for obtaining illuminance measurement results is such that, in the first or second embodiment, the illuminance measured at the second three-dimensional position is the illuminance measured by an illuminance measuring unit mounted on an unmanned aerial vehicle that moves by automatic or remote control.

[0012] This third aspect provides an example of an illuminance measurement method using an illuminance measuring unit mounted on an unmanned aerial vehicle that moves by automatic or remote control.

[0013] The fourth embodiment of the illuminance measurement result acquisition device is an illuminance measurement result acquisition device that acquires the illuminance measurement result at a first three-dimensional position under predetermined lighting conditions, and comprises a calculation unit that calculates the illuminance measurement result at the first three-dimensional position under predetermined lighting conditions based on the illuminance measured at a second three-dimensional position that differs only in height from the first three-dimensional position under the predetermined lighting conditions.

[0014] In the fifth embodiment, the illuminance measurement result acquisition device is configured such that, as in the fourth embodiment, the first illuminance at the first three-dimensional position calculated according to the predetermined lighting conditions is LXth1, the second illuminance at the second three-dimensional position calculated according to the predetermined lighting conditions is LXth2, the illuminance measured at the second three-dimensional position is LXm2, and the measurement result of the illuminance at the first three-dimensional position under the predetermined lighting conditions is LXm1, the calculation unit calculates LXm1 according to the formula LXm1 = LXm2·LXth1 / LXth2.

[0015] The illuminance measurement result acquisition device according to the sixth embodiment is such that, in the fourth or fifth embodiment, the illuminance measured at the second three-dimensional position is the illuminance measured by an illuminance measuring unit mounted on an unmanned aerial vehicle that moves by automatic or remote control.

[0016] The fourth to sixth embodiments are devices for acquiring illuminance measurement results, corresponding to the first to third embodiments, respectively.

[0017] The seventh embodiment of the illuminance measurement result acquisition program is a program that causes a computer to function as an illuminance measurement result acquisition device according to any of the fourth to sixth embodiments. Examples of the computer include a notebook personal computer, a tablet, and a smartphone.

[0018] The illuminance measurement system according to the eighth embodiment comprises an illuminance measurement result acquisition device according to the sixth embodiment, and the unmanned aerial vehicle on which the illuminance measurement unit is mounted and which moves by automatic or remote control.

[0019] According to this eighth aspect, since the unmanned aerial vehicle is equipped with the illuminance measuring unit and moves by automatic or remote control, it is no longer necessary for a person with an illuminance measuring unit, such as an illuminometer, to move to each measurement location to actually measure the illuminance, and illuminance can be measured while reducing manpower.

[0020] Furthermore, according to the eighth embodiment, since the device for acquiring illuminance measurement results according to the sixth embodiment is provided, even if it is not possible to actually measure the illuminance at the first three-dimensional position due to constraints on the movement of the unmanned aerial vehicle, the measurement result of the illuminance at the first three-dimensional position under the predetermined lighting conditions can be obtained with high accuracy.

[0021] The illuminance measurement system according to the ninth embodiment is equipped with a display device that receives the illuminance measured by the illuminance measurement unit via wireless communication outside the unmanned aerial vehicle and displays it to a person in real time.

[0022] According to this ninth embodiment, the system is equipped with a display device that receives the illuminance measured by the illuminance measuring unit via wireless communication outside the unmanned aerial vehicle and displays it to a person in real time, so that person can check the measurement results in real time. Therefore, if the displayed measurement results deviate significantly from the expected results, it is possible to know in real time that the measurement is being performed in an abnormal state, and the measurement can be temporarily interrupted to check whether the unmanned aerial vehicle or the illuminance measuring unit is malfunctioning, and if so, repair or replace it before conducting the measurement in a normal state, thereby improving the reliability of the measurement. Furthermore, if the person receiving the display of the measurement results is a witness other than the person performing the measurement, it helps the witness to confirm that the measurement is being performed appropriately, making it less likely for inappropriate or fraudulent measurements to be taken, thus improving the reliability of the measurement.

[0023] The illuminance measurement system according to the tenth aspect, in the ninth aspect, the illuminance measurement unit has a first display unit that displays the actual measurement result, and the unmanned aircraft is equipped with an imaging unit that captures an image of the display image of the first display unit, and a first communication unit that wirelessly transmits in real time the transmission information including the display image captured by the imaging unit. The presentation device has a second communication unit that receives the transmission information transmitted by the first communication unit directly or via relay means, and a second display unit that displays at least the display image among the transmission information received by the second communication unit in real time.

[0024] In this tenth aspect, the display unit of the illuminance measurement unit is imaged on the unmanned aircraft, and the captured display image is displayed on the display unit of the presentation device via wireless communication. Therefore, according to the tenth aspect, a handy type measuring instrument or the like that does not have a function of outputting the actual measurement result as a data signal can be used as the illuminance measurement unit. For this reason, according to the tenth aspect, even a handy type measuring instrument or the like that does not have a function of outputting the actual measurement result as a data signal can be used as the illuminance measurement unit after, for example, receiving a predetermined certification or inspection, and a highly reliable measuring instrument can be used as the illuminance measurement unit, thereby improving the reliability of the measurement. Note that in the tenth aspect, the illuminance measurement unit may have not only a function of displaying the actual measurement result on the display unit but also a function of outputting the actual measurement result as a data signal.

[0025] The illuminance measurement system according to the eleventh aspect, in the tenth aspect, includes a recognition unit that recognizes the actual measurement result from the display image among the transmission information received by the second communication unit, and the calculation unit of the acquisition device calculates the measurement result of the illuminance at the first three-dimensional position based on the actual measurement result recognized by the recognition unit.

[0026] According to this eleventh aspect, a recognition unit for recognizing the measured result from the display image is provided, and the calculation unit of the acquisition device calculates the measurement result of the illuminance at the first three-dimensional position based on the measured result recognized by the recognition unit. Therefore, the calculation unit of the acquisition device automatically calculates the measurement result of the illuminance at the first three-dimensional position. However, in the ninth and tenth aspects, the acquisition device may be configured to calculate the measurement result of the illuminance at the first three-dimensional position in response to, for example, an input operation of the measured result by a person who has received the presentation of the measured result by the presentation device or an operation to start acquiring the measurement result of the illuminance at the first three-dimensional position.

[0027] The illuminance measurement system according to the twelfth aspect has, in the ninth aspect, the illuminance measurement unit having a first display unit that displays the measured result. The unmanned aerial vehicle is equipped with an imaging unit that captures the display image of the first display unit, a recognition unit that recognizes the measured result from the display image captured by the imaging unit, and a first communication unit that wirelessly transmits in real time the transmission information including the measured result recognized by the recognition unit. The presentation device has a second communication unit that receives the transmission information transmitted by the first communication unit directly or via relay means, and a second display unit that displays at least the measured result among the transmission information received by the second communication unit in real time.

[0028] In this twelfth aspect, the display unit of the illuminance measurement unit is captured on the unmanned aerial vehicle, the measured result is recognized from the captured display image, and the recognized measured result is displayed on the display unit of the presentation device via wireless communication. Therefore, according to the twelfth aspect, a handy-type measuring instrument or the like that does not have a function of outputting the measured result as a data signal can be used as the illuminance measurement unit. For this reason, according to the twelfth aspect, even a handy-type measuring instrument or the like that does not have a function of outputting the measured result as a data signal can be used as the illuminance measurement unit after, for example, receiving a predetermined certification or verification, and a highly reliable measuring instrument can be used, thereby improving the reliability of the measurement.

[0029] In the 13th embodiment of the illuminance measurement system, the acquisition device is mounted on the unmanned aerial vehicle, and the calculation unit of the acquisition device calculates the illuminance measurement result at the first three-dimensional position based on the actual measurement result recognized by the recognition unit.

[0030] According to this 13th embodiment, the calculation unit of the acquisition device calculates the illuminance measurement result at the first three-dimensional position based on the measurement result recognized by the recognition unit, so the calculation unit of the acquisition device automatically calculates the illuminance measurement result at the first three-dimensional position. However, in the 12th embodiment, the acquisition device may be configured to calculate the illuminance measurement result at the first three-dimensional position in response to, for example, an input operation of the measurement result by a person who has received the measurement result from the presentation device, or an operation to start acquiring the illuminance measurement result at the first three-dimensional position.

[0031] The illuminance measurement system according to the 14th embodiment, in the 9th embodiment, has an illuminance measurement unit having a first display unit for displaying the measured result, the unmanned aerial vehicle being equipped with an imaging unit for capturing an image of the display unit, and a first communication unit for wirelessly transmitting transmission information including the image captured by the imaging unit in real time, and the display device having a second communication unit for receiving the transmission information transmitted by the first communication unit directly or via a relay means, a recognition unit for recognizing the measured result from the display image among the transmission information received by the second communication unit, and a second display unit for displaying the measured result recognized by the recognition unit in real time.

Therefore, according to the 14th embodiment, a measuring instrument such as a handheld type that does not have the function of outputting the measurement result as a data signal can be used as the illuminance measuring unit. For this reason, according to the 14th embodiment, even if a measuring instrument such as a handheld type that does not have the function of outputting the measurement result as a data signal is used, a highly reliable measuring instrument can be used as the illuminance measuring unit, for example, by undergoing a prescribed certification or inspection, thereby improving the reliability of the measurement.

[0033] In the 15th embodiment of the illuminance measurement system, the calculation unit of the acquisition device calculates the illuminance measurement result at the first three-dimensional position based on the actual measurement result recognized by the recognition unit.

[0034] According to this 15th embodiment, the calculation unit of the acquisition device calculates the illuminance measurement result at the first three-dimensional position based on the measurement result recognized by the recognition unit, so the calculation unit of the acquisition device automatically calculates the illuminance measurement result at the first three-dimensional position. However, in the 14th embodiment, the acquisition device may be configured to calculate the illuminance measurement result at the first three-dimensional position in response to, for example, an input operation of the measurement result by a person who has received the measurement result from the presentation device, or an operation to start acquiring the illuminance measurement result at the first three-dimensional position.

[0036] According to this 16th embodiment, the system is equipped with a display device that receives the illuminance measurement results acquired in real time by the acquisition device via wireless communication outside the unmanned aerial vehicle and presents them to a person in real time. This allows the person to confirm the illuminance measurement results at the first three-dimensional position in real time. Therefore, if the presented measurement results deviate significantly from the expected results, the person can know in real time that the measurement is being performed under abnormal conditions. This allows the measurement to be temporarily interrupted, and the unmanned aerial vehicle or illuminance measurement unit to be inspected for malfunctions, and if malfunctions are found, repairs or replacements can be carried out before the measurement can be performed under normal conditions, thereby improving the reliability of the measurement. Furthermore, if the person receiving the presentation of the measurement results is a witness other than the person performing the measurement, this can help the witness confirm that the measurement is being performed appropriately, making it less likely for inappropriate or fraudulent measurements to be performed, thus improving the reliability of the measurement.

In this 17th embodiment, the illuminance measurement result acquired by the acquisition device is displayed on the display unit of the display device via wireless communication. Therefore, according to this 17th embodiment, a measuring instrument such as a handheld type that does not have the function of outputting the measurement result as a data signal can be used as the illuminance measurement unit. Thus, according to this 17th embodiment, even if a measuring instrument such as a handheld type that does not have the function of outputting the measurement result as a data signal is used, a highly reliable measuring instrument can be used as the illuminance measurement unit, for example, by undergoing a predetermined certification or inspection, thereby improving the reliability of the measurement.

This allows the person to check the illuminance measurement results at the first three-dimensional position in real time. Therefore, if the presented measurement results deviate significantly from the expected results, the person can know in real time that the measurement is being performed under abnormal conditions. This allows the measurement to be temporarily interrupted, the unmanned aerial vehicle and the illuminance measurement unit to be inspected for malfunctions, and if they are found to be malfunctions, repairs or replacements can be made before the measurement can be performed under normal conditions, thereby improving the reliability of the measurement. Furthermore, if the person receiving the presentation of the measurement results is a witness other than the person performing the measurement, this can help the witness confirm that the measurement is being performed appropriately, making it less likely for inappropriate or fraudulent measurements to be performed, thus improving the reliability of the measurement.

Therefore, a person who receives the measured illuminance and / or the measurement result of the illuminance calculated therefrom may not record it by writing on recording paper, but may instead use the measurement result and the current position at the time the measurement result was obtained, read later from the storage unit, as the final measurement result. Even in this case, the possibility of errors such as writing errors can be reduced compared to recording by hand at the measurement site, thereby improving the reliability of the measurement.

[0063] The illuminance measurement system 1 according to this embodiment is a system for measuring illuminance at a predetermined number of measurement positions P(P1, P2) in a boat race track where a large lighting device (not shown) is installed. Here, P indicates a two-dimensional position in the horizontal plane, P1 indicates a three-dimensional position with height H1 at the same two-dimensional position as P, and P2 indicates a three-dimensional position with height H2 at the same two-dimensional position as P (see Figures 2 and 3). Heights H1 and H2 are different. In this embodiment, P1 indicates the position from which the illuminance measurement result should be obtained (first three-dimensional position), and P2 indicates the position from which the illuminance is actually measured (second three-dimensional position). In this embodiment, the heights H1 of the three-dimensional position P1 at each measurement position P are the same, and the heights H2 of the three-dimensional position P2 at each measurement position P are the same, but the present invention is not necessarily limited to this.

[0064] Figure 2 is a schematic diagram showing an aerial photograph (equivalent to a two-dimensional map based on latitude and longitude) of a portion of a boat race track, with measurement points P plotted as black circles and a predetermined flight path L indicated. However, in Figure 2, the route from the ground takeoff position to the measurement point P at one end of the flight path L, and the route from the other end of the flight path L to the ground landing position are omitted from the illustration. One flight is defined as the flight from the ground takeoff position to the next ground landing position where the unmanned aircraft 11 lands. In Figure 2, 82, 83, and 84 are boundary structures (wave-dissipating devices, etc.) that form the outer boundary of the competition area 81 near the shore, and 85 is the grandstand.

[0065] The facility in which the illuminance measuring system according to the present invention measures illuminance, etc., is not limited to boat race tracks, but may also be other outdoor or indoor sports venues (for example, baseball fields, soccer fields, athletics stadiums, tennis courts, horse racing tracks, auto racing tracks, etc.).

[0066] Figure 3 is a schematic cross-sectional view, including the vertical direction (height direction), illustrating the measurement situation when the unmanned aerial vehicle 11 in Figure 1 reaches one of the measurement positions P (actual measurement position P2) in Figure 2. In Figure 3, 89 is seawater, 89a is the sea surface, 89b is the seabed, and 90 is the float section. The unmanned aerial vehicle 11 will be described in detail later with reference to Figures 4 and 5.

[0067] The large-scale lighting system at the boat race track in this example is designed to obtain the desired illuminance distribution at an average height H1 between the maximum tide level (highest tide level) and the minimum tide level (lowest tide level) of the sea surface 89a. After the installation of the large-scale lighting system, in order to demonstrate that the desired illuminance distribution can be obtained in the horizontal plane at height H1 under predetermined lighting conditions (number of floodlights, output, angle, distance, etc.) provided by the large-scale lighting system, the illuminance measurement system 1 according to this embodiment is used to obtain illuminance measurement results at a predetermined number of measurement positions P (positions P1 from which illuminance measurement results should be obtained) under the predetermined lighting conditions.

[0068] However, in order to safely fly the unmanned aircraft 11 despite the effects of changes in tide level, waves, wind, etc., it is not possible to fly it at a very low altitude. Therefore, the height of the light-receiving window 41a of the light-receiving unit 41, which is the sensor unit of the illuminance meter 34 mounted on the unmanned aircraft 11, cannot be set to height H1, and the illuminance at position P1 at height H1 cannot be measured by the illuminance meter 34.

[0069] Therefore, in this embodiment, as shown in Figure 3, the unmanned aerial vehicle 11 is moved so that the height of the light-receiving window 41a is at position P2 at height H2, and the illuminance at position P2 at height H2 is measured by the illuminance meter 34. Height H2 is set so that the difference from height H1 is relatively small, within a range that allows the unmanned aerial vehicle 11 to fly safely regardless of changes in tide level, waves, wind, etc.

[0070] The method for obtaining illuminance measurement results used in this embodiment is a method for obtaining illuminance measurement results LXm1 at a first three-dimensional position P1 under predetermined lighting conditions, and calculates the illuminance measurement result LXm1 at the first three-dimensional position P under predetermined lighting conditions based on the illuminance LXm2 measured at a second three-dimensional position P2 that differs only in height from the first three-dimensional position P1 under predetermined lighting conditions.

[0071] Specifically, in the method for obtaining illuminance measurement results used in this embodiment, when the first illuminance at the first three-dimensional position P1 calculated according to the predetermined lighting conditions is defined as LXth1, and the second illuminance at the second three-dimensional position P2 calculated according to the predetermined lighting conditions is defined as LXth2, LXm1 is calculated according to the formula LXm1 = LXm2·LXth1 / LXth2. LXth1 is calculated in the first place using known design methods during the design of the large-scale lighting device, and LXth2 can be calculated in advance using the same method as LXth1.

[0072] According to this method for obtaining illuminance measurement results, the illuminance measurement result at the first three-dimensional position P1 under the predetermined lighting conditions is calculated based on the illuminance LXm2 measured at the second three-dimensional position P2, which differs from the first three-dimensional position P1 only in height under the predetermined lighting conditions. Therefore, if the difference between the height H1 of the first three-dimensional position P1 and the height H2 of the second three-dimensional position P2 is not too large, the illuminance measurement result LXm1 at the first three-dimensional position P1 under the predetermined lighting conditions can be obtained with high accuracy.

[0073] Furthermore, in the method for obtaining illuminance measurement results used in this embodiment, LXm1 is calculated according to the formula LXm1 = LXm2·LXth1 / LXth2. Since LXm2 is used and then the ratio LXth1 / LXth2 of LXth1 and LXth2 is used, the illuminance measurement result LXm1 at the first three-dimensional position P1 under the predetermined lighting conditions can be obtained with greater accuracy.

[0074] As shown in Figure 1, the illuminance measurement system 1 according to this embodiment includes an unmanned aerial vehicle 11 that moves to the measurement position P (actual measurement position P2) by automatic or remote control, an operating device 12, a display device for witnesses 13, and an illuminance measurement result acquisition device 14 that implements the method for acquiring the illuminance measurement results described above.

[0075] In this embodiment, the unmanned aerial vehicle 11 is equipped with two communication units 27A and 27B, the operator 12 has three communication units 67A, 67B, and 67C, and the witness display device 13 has one communication unit 75. As will be described later, wireless communication is performed between communication unit 27A and communication unit 67A, between communication unit 27B and communication unit 67B, and between communication unit 67C and communication unit 75, each at a different frequency. The antennas of communication units 27A and 27B may be separate, or they may share a single antenna. Similarly, the antennas of communication units 67A, 67B, and 67C may be separate, or they may share a single antenna.

[0076] Figure 4 is a schematic block diagram showing the unmanned aerial vehicle 11 in Figure 1. Figure 5 is a schematic front view showing the unmanned aerial vehicle 11 in Figure 1. Figure 6(a) is a schematic side view of the main parts showing the state of the unmanned aerial vehicle 11 in Figure 1 when horizontal illuminance is measured. Figure 6(b) is a schematic side view of the main parts showing the state of the unmanned aerial vehicle 11 in Figure 1 when vertical illuminance is measured.

[0077] In this embodiment, the unmanned aerial vehicle 11 is referred to as a drone or multicopter, and as shown in Figure 5, it comprises a main body 51, a plurality of rotors 31 (for example, 4, 6, or 8) arranged radially with respect to the main body 51 in a plan view, and skids 52.

[0078] Furthermore, in this embodiment, as shown in Figure 4, the unmanned aerial vehicle 11 includes, in addition to the two communication units 27A and 27B mentioned above, a CPU 21, a ROM 22, a RAM 23, an input / output interface 24 connected to external devices (not shown), a display unit 25 such as a liquid crystal display panel, a camera (digital camera) 26 for capturing images of the front of the unmanned aerial vehicle 11 for use in manual remote control, a storage device 28 such as a hard disk, SSD, or eMMC, a GPS receiver 29 as a position detection unit for detecting the current position of the unmanned aerial vehicle 11, and a gyroscope and acceleration sensor. The aircraft is equipped with a sensor group 30 including various sensors for controlling the flight and attitude of the aircraft, a motor 32 for rotating the rotor blades 31, a drive unit 33 for driving the motor 32 under the control of a CPU 21, an illuminance meter 34 as an illuminance measuring unit for measuring the illuminance at a measurement position P (actual measurement position P2), an illuminance meter display unit imaging camera (digital camera) 35 as an imaging unit for capturing the display image of the display unit 44 of the illuminance meter 34, a battery 37 consisting of a secondary battery for supplying power to elements other than the illuminance meter 34, and a bus 36 for interconnecting each element other than the illuminance meter 34 as shown in Figure 4.

[0079] Various programs are pre-installed in the storage device 28, and by loading and executing these programs, the CPU 21 and other components realize the functions described below.

[0080] Although not shown in the drawing, most of the elements in Figure 4, other than the camera 35 for imaging the illuminance meter display unit and the illuminance meter 34, are located on the main body 51.

[0081] In this embodiment, the illuminance meter 34 is a handheld digital illuminance meter and has a light-receiving unit 41 as a sensor unit and a main unit 42 configured separately from the light-receiving unit 41. The light-receiving unit 41 and the main unit 42 are connected by a cable (not shown). The main unit 42 has a display unit 44 that displays the measured illuminance value as an image numerically, a measurement processing unit 43 that receives a light signal from the light-receiving unit 41, obtains an illuminance value corresponding to the light signal, and displays the illuminance value as an image on the display unit 44, and a battery 45 such as a dry cell battery that supplies power to each part. Although not shown in the drawings, the illuminance meter 34 has a power switch, and when the power is turned on by the power switch, the illuminance measurement operation is repeated until the power is turned off, and the measured illuminance values ​​are continuously displayed on the display unit 41 in real time.

[0082] In this embodiment, the main body 42 of the illuminance meter 34 is detachably attached to the main body 51 of the unmanned aerial vehicle 11 by a mounting bracket 54, as shown in Figure 5, and is positioned below the main body 51. The camera 35 for capturing images of the illuminance meter display is attached to the main body 51 by the mounting bracket 55 and is positioned below the main body 51, facing the display unit 44 of the illuminance meter 34.

[0083] In this embodiment, as shown in Figures 5 and 6, the light-receiving unit 41 of the illuminance meter 34 is detachably attached by a mounting bracket 56 to the upper end of a support column 53 whose lower end is fixed to the upper part of the main body 51 of the unmanned aerial vehicle 11, and is positioned above the main body 51. In Figures 5 and 6, 41a is the light-receiving window of the light-receiving unit 41. In this embodiment, as shown in Figure 6, the orientation of the light-receiving unit 41 can be manually switched by 90° relative to the unmanned aerial vehicle using the mounting bracket 56, thereby allowing switching between orientation for measuring horizontal illuminance and orientation for measuring vertical illuminance. Various known structures can be adopted for the specific structure of the mounting bracket 56.

[0084] In this embodiment, when in autopilot mode, the unmanned aircraft 11 performs horizontal and vertical illuminance measurements at all predetermined measurement positions P (actual measurement positions P2) at the boat race track through multiple flights. Multiple flights are performed because attempting to move to all measurement positions P (actual measurement positions P2) in a single flight could result in the battery 37 running out of power midway, and because the orientation of the light-receiving section 41 of the illuminance meter 34 cannot be switched from the orientation for horizontal illuminance measurement shown in Figure 6(a) to the orientation for vertical illuminance measurement shown in Figure 6(b), or vice versa, without first landing. However, if, for example, the capacity of the battery 37 is sufficiently large for the power consumption when moving to all measurement positions P (actual measurement positions P2) in a single flight and performing actual measurements at those positions, and if only one of the horizontal plane illuminance measurement and vertical plane illuminance measurement is performed, or if the orientation of the light receiving unit 41 can be switched remotely using an actuator for switching the orientation of the light receiving unit 41, or if two illuminance meters 34 are installed, one for horizontal plane illuminance measurement and the other for vertical plane illuminance measurement, then it is possible to perform actual measurements at all predetermined measurement positions P (actual measurement positions P2) of the boat race track in a single flight of the unmanned aircraft 11.

[0085] Figure 7 is a schematic block diagram showing the control unit 12 in Figure 1. In addition to the three communication units 67A, 67B, and 67C mentioned above, the control unit 12 includes a CPU 61, a ROM 62, a RAM 63, an input / output interface 64 connected to external devices (not shown), a display unit 65 such as a liquid crystal display panel, a storage device 68 such as a hard disk, SSD, or eMMC, an operation unit 66 for the pilot to give various instructions to the unmanned aerial vehicle 11, a bus 69 connecting these components as shown in Figure 7, and a battery 70 consisting of secondary batteries that supply power to each of the elements in Figure 7.

[0086] Various programs are pre-installed in the storage device 68, and by loading and executing these programs, the CPU 61 and other components realize the functions described below.

[0087] In this embodiment, the storage device 68 is pre-stored with the following data using, for example, a personal computer connected to the input / output interface 64. Specifically, the storage device 68 is pre-stored with data corresponding to each of the N divided regions, which are formed by dividing the entire area containing all predetermined measurement positions P (actual measurement positions P2) of the boat race track into N regions (where N is an integer of 2 or more). This data includes data indicating the measurement positions P (actual measurement positions P2) included in the divided region, data indicating a flight path that traces the measurement positions P (actual measurement positions P2) included in the divided region in a single stroke and minimizes the path length (flight path data corresponding to the divided region), and aerial photograph data corresponding to the divided region. For example, if one of the N divided regions is the region shown in Figure 2, the storage device 68 is pre-stored with data indicating the measurement position P (actual measurement position P2) in Figure 2, data indicating the flight path L in Figure 2 corresponding to the divided region, and aerial photograph data corresponding to the divided region (data showing an aerial photograph including boundary formations 82, 83, 84 and stand 85 in Figure 2).

[0088] Figure 8 is a schematic block diagram showing the witness display device 13 in Figure 1. The witness display device 13 presents the actual measurement results in real time to witnesses (measurement witnesses), such as the manager of the facility (in this embodiment, a boat race track) where illuminance is measured. In addition to the one communication unit 75 mentioned above, the witness display device 13 includes a CPU 71, a ROM 72, a RAM 73, an input / output interface 74 connected to external devices (not shown), a storage device 76 such as a hard disk, SSD, or eMMC, a touch panel that serves as both a display unit 77 and an operation unit 78, a bus 79 that connects these to each other as shown in Figure 8, and a battery 80 consisting of secondary batteries that supply power to each element in Figure 8.

[0089] The storage device 76 has various programs pre-installed in addition to the measurement result presentation program, and by reading and executing these programs, the CPU 71 and other components realize the functions described below. Note that the computer constituting the presentation device according to the present invention is not limited to a personal computer, but may also be a tablet or smartphone.

[0090] Figure 9 is a schematic block diagram showing the illuminance measurement result acquisition device 14 in Figure 1. The illuminance measurement result acquisition device 14 implements the illuminance measurement result acquisition method described above. The illuminance measurement result acquisition device 14 includes a CPU 91, a ROM 92, a RAM 93, an input / output interface 94 connected to external devices (not shown), a communication unit 95, a storage device 96 such as a hard disk, SSD, or eMMC, a display unit 97, a touch panel that also serves as an operation unit 98, a bus 99 connecting these to each other as shown in Figure 10, and a battery 80 consisting of secondary batteries that supply power to each element in Figure 9.

[0091] The storage device 96 has various programs pre-installed, including a program for acquiring illuminance measurement results. By loading and executing these programs, the CPU 91 and other components realize the functions described below. Note that the computer constituting the acquisition device according to the present invention is not limited to a personal computer, but may also be a tablet or smartphone.

[0092] In this embodiment, for all measurement positions P, the ratio [LXth1 / LXth2] for each measurement position P is associated with that measurement position P and is pre-stored in the storage device 96. In this embodiment, when the operator inputs the measured illuminance LXm2 at each measurement position P using the operation unit 98 and commands the operation unit 98 to start acquiring the illuminance measurement result LXm1 at each measurement position P (position P1 from which the measurement result should be obtained), the illuminance measurement result LXm1 at each measurement position P (position P1 from which the measurement result should be obtained) is calculated according to the above formula by multiplying the input measured illuminance LXm2 by the coefficient (value of the ratio [LXth1 / LXth2]). The calculated illuminance measurement result LXm1 for each measurement position P is, for example, stored in the storage device 96, displayed on the display unit 97, or printed by a printer (not shown) for the desired use.

[0093] When performing illuminance measurement using autopilot mode, the operator checks the orientation of the light receiving unit 41 of the illuminance meter 34 while the unmanned aircraft 11 is landed. If the orientation is, for example, the orientation for horizontal illuminance measurement shown in Figure 6(a), the operator gives an instruction via the control unit 66 of the control device 12 to select one of the N divided regions that has not yet been selected and perform horizontal illuminance measurement for that region using autopilot mode.

[0094] In response to this instruction, the CPU 61 of the operating unit 12 reads the measurement position P (actual measurement position P2) and the flight path L corresponding to the division area, which are pre-stored in the storage device 68, and supplies control commands to the unmanned aerial vehicle 11 via wireless communication between the communication unit 67A and the communication unit 27A, which are necessary for the unmanned aerial vehicle 11 to fly along the flight path L, to remain stationary at each measurement position P (actual measurement position P2) in a predetermined attitude for a predetermined time, and finally to land at the final landing position of the flight path L. The CPU 21 of the unmanned aerial vehicle 11 controls the drive unit 33 and, consequently the rotor blades 31, etc., in accordance with the control commands, thereby realizing the aforementioned operation of the unmanned aerial vehicle 11. In this embodiment, as described above, the altitude of the unmanned aerial vehicle 11 is maintained at a low predetermined altitude H2, for example, within a range where it is not affected by waves, etc.

[0095] During the operation of the unmanned aerial vehicle 11, the CPU 61 of the control unit 12 sends in real time, via wireless communication between the communication unit 27B and the communication unit 67B, the current position (latitude and longitude) and altitude of the unmanned aerial vehicle 11 from the GPS receiver 29, the attitude and speed of the unmanned aerial vehicle 11 based on signals from the sensor group 30, and the display image of the display unit 44 of the illuminance meter 34, which is captured in real time by the illuminance meter display camera 35. Based on this information sent from the unmanned aerial vehicle 11, the CPU 61 of the control unit 12 generates in real time image data, such as the display image shown in Figure 10, excluding the display of the display area 88 described later, and sends this image data in real time to the witness presentation device 13 via wireless communication between the communication unit 67C and the communication unit 75. The CPU 71 of the witness display device 13 adds a display area 88 (for example, a display for a predetermined operation on the touch panel) to the image sent from the operating device, and displays the display image shown in Figure 10 on the touch panel which functions as a display unit 77.

[0096] Figure 10 is a schematic diagram showing an example of a display image shown in the display unit 77 of the witness presentation device 13 in Figure 1. The display image shown in Figure 10 shows an example where the currently selected divided area is the area shown in Figure 2. The display image shown in Figure 10 is a superimposed image created by superimposing an aerial photograph, flight path L, and measurement position P(P1, P2) corresponding to the divided area, and further superimposing a mark G indicating the current position of the unmanned aerial vehicle 11. This image is then combined with the image captured by the illuminance meter display unit imaging camera 35, which includes the display image 86a of the display unit 44 of the illuminance meter 34, the display in the display area 88, and the display in the display area 87. Although not shown in Figure 10, the display area 87 displays the latitude, longitude, and altitude indicating the current position of the unmanned aerial vehicle 11, the speed of the unmanned aerial vehicle 11, and, if necessary, an indication of whether the current measurement is horizontal or vertical illuminance, and the current attitude of the unmanned aerial vehicle 11.

[0097] In this embodiment, the CPU 61 of the control unit 12 displays an image on the display unit 65 of the control unit 12 in real time, such as the display image shown in Figure 10 with the display area 88 removed, based on the selection of a display mode by the operation unit 66. In this display mode, the control unit 12 also functions as a presentation device. In this display mode, the CPU 61 of the control unit 12 notifies the pilot or an assistant next to them of the timing (measurement timing) when a predetermined time has elapsed since the unmanned aerial vehicle 11 came to rest at each measurement position P (actual measurement position P2) by display on the display unit 65 or by sound. In this embodiment, the pilot or the assistant looks at the display image on the display unit 65, such as the display image shown in Figure 10 with the display area 88 removed, and records the actual illuminance at the measurement position P (actual measurement position P2) by writing it on recording paper. Furthermore, at the measurement timing, the CPU 61 of the operating device 12 stores in the storage device 68 an image similar to the display image shown in Figure 10, but with the display area 88 removed. The image stored in this way is an example of a correlation between the measured illuminance result and the current position of the unmanned aerial vehicle 11 at the time the measured result was obtained. Such an image can be read by, for example, a personal computer connected to the input / output interface 64. Instead of storing such an image in the storage device 68, the CPU 21 of the unmanned aerial vehicle 11 may correlate the image captured by the illuminance meter display camera 35 at the measurement timing with the current position from the GPS receiver 29, and if necessary, also correlate information such as the attitude and speed of the unmanned aerial vehicle 11 at the measurement timing, and store this information in the storage device 28 of the unmanned aerial vehicle 11. Such information can be read by, for example, a personal computer connected to the input / output interface 24 after the unmanned aerial vehicle 11 lands.

[0098] In this way, once the horizontal illuminance measurement for the currently selected divided area is completed and the unmanned aircraft 11 lands, the operator replaces the battery 37 of the unmanned aircraft 11 with a charged one, switches the orientation of the light receiving unit 41 of the illuminance meter 34 to the orientation for vertical illuminance measurement shown in Figure 6(b), and then performs vertical illuminance measurement for the currently selected divided area in the same manner as the horizontal illuminance measurement for the currently selected divided area described above. In this embodiment, the measurement position for horizontal illuminance measurement and vertical illuminance measurement are the same, but in the present invention, the two may be different.

[0099] In this manner, once both horizontal and vertical illuminance measurements are completed for the currently selected divided region, the same process is carried out for the remaining unselected divided region, and the series of measurements is completed when both horizontal and vertical illuminance measurements are completed for all divided regions.

[0100] Subsequently, the assistant or other person inputs the measured illuminance LXm2 at each measurement position P (measurement position P2) written on the recording paper using the operation unit 98 of the illuminance measurement result acquisition device 14, and commands the operation unit 98 to start acquiring the measured illuminance LXm1 at each measurement position P (position P1 from which the measurement result should be obtained). In response, the acquisition device 14 calculates the measured illuminance LXm1 at each measurement position P (position P1 from which the measurement result should be obtained) according to the formula described above by multiplying the input measured illuminance LXm2 by the coefficient (value of the ratio [LXth1 / LXth2]).

[0101] In this embodiment, illuminance measurement can be performed not only in automatic control mode but also in manual remote control mode.

[0102] For example, in response to a request from the aforementioned VIP seat in the stands (e.g., a request via transceiver), if it is necessary to measure illuminance at a desired measurement position other than the measurement position P in the autopilot mode, the operator switches the orientation of the light receiving unit 41 of the illuminance meter 34 to the requested orientation for horizontal or vertical illuminance measurement while the unmanned aircraft 11 is landed. Subsequently, the operator gives an instruction via the control unit 66 of the control device 12 to perform illuminance measurement in manual remote control mode. In response to this instruction, the operator moves the unmanned aircraft 11 to the desired measurement position and stops it there in the desired orientation, similar to manual remote control of a normal drone, by operating the control unit 66. At this time, the CPU 61 of the control unit 12 uses the current position information of the unmanned aerial vehicle 11 from the unmanned aerial vehicle 11 to display in real time on the display unit 77 of the witness presentation device 13 and the display unit 65 of the control unit 12 a display image, such as the one shown in Figure 10, or an image with the display of the display area 88 removed, similar to when the divisional region containing the current position is selected in the autopilot mode. In such an image, the current position mark G is often outside the flight path L. When the operator instructs via the control unit 66 that the unmanned aerial vehicle 11 has stopped at the desired measurement position and orientation and the desired measurement timing has been reached, the CPU 61 of the control unit 12 responds to this instruction by storing in the storage device 68 an image, such as the display image shown in Figure 10 with the display of the display area 88 removed. Furthermore, at this measurement timing, the operator or assistant views the display image of the display unit 65, excluding the display area 88 as shown in Figure 10, and records the illuminance at the measurement position by writing it on recording paper. Even in this manual remote control mode for illuminance measurement, for example, the height of the actual measurement position can be the same as the height H2 of the measurement position P (actual measurement position P2) in the automatic control mode.

[0103] In this embodiment, for all positions that can be used as measurement locations in manual remote control mode illuminance measurement, the ratio [LXth1 / LXth2] value for each position is associated with that position as a coefficient and is pre-stored in the storage device 96.

[0104] After the manual remote control mode measurement of illuminance is completed and the recorded illuminance values ​​at each measurement location are written on the recording paper, the assistant or other person inputs the measured illuminance LXm2 at each measurement location (measurement location) written on the recording paper using the operation unit 98 of the illuminance measurement result acquisition device 14, and commands the operation unit 98 to start acquiring the illuminance measurement result LXm1 at each measurement location (location where measurement results should be obtained). In response, the acquisition device 14 calculates the illuminance measurement result LXm1 at each measurement location (location where measurement results should be obtained) according to the formula described above by multiplying the input measured illuminance LXm2 by the coefficient (value of the ratio [LXth1 / LXth2]).

[0105] According to this embodiment, the unmanned aerial vehicle 11 moves to a measurement position by automatic or remote control, and is equipped with an illuminance meter 34 for measuring the illuminance at the measurement position. Therefore, it is not necessary for a person with an illuminance meter 34 to move to each measurement position to measure the illuminance, and illuminance can be measured while reducing manpower.

[0106] Furthermore, according to this embodiment, the unmanned aerial vehicle 11 is equipped with a display device 13 that receives the actual illuminance measurement result LXm2 from the illuminance meter 34 via wireless communication and displays it to a person in real time, as well as an operating device 12 that functions as a display device. As a result, the person can check the actual measurement result LXm2 in real time. Therefore, if the displayed actual measurement result LXm2 deviates significantly from the expected result, the person can know in real time that the measurement is being performed under abnormal conditions. This allows the measurement to be temporarily interrupted, the unmanned aerial vehicle 11 and the illuminance meter 34 to be inspected for malfunctions, and if they are malfunctions, repairs or replacements can be made before the measurement can be performed under normal conditions, thereby improving the reliability of the measurement. In addition, since a witness other than the person taking the measurement receives the actual measurement result LXm2 via the witness display device 13, it helps the witness to confirm that the measurement is being performed appropriately, making it less likely for inappropriate or fraudulent measurements to be taken, thus improving the reliability of the measurement.

[0107] Furthermore, in this embodiment, the display unit of the illuminance meter 34 is imaged by the illuminance meter display unit imaging camera 35 on the unmanned aerial vehicle 11, and the imaged display is displayed via wireless communication on the display unit 77 of the witness presentation device 13 or the display unit 65 of the operating device 12 which functions as a presentation device. Therefore, according to this embodiment, a handheld type or other illuminance meter that does not have the function of outputting measurement results as a data signal can be used as the illuminance meter 34. For this reason, according to this embodiment, even a handheld type or other illuminance meter that does not have the function of outputting measurement results as a data signal can be used as the illuminance meter 34 if it has undergone a certain certification or inspection to ensure high reliability, thereby improving the reliability of the measurement. Note that the illuminance meter 34 may have the function of not only displaying the measurement results on the display unit but also outputting the measurement results as a data signal.

[0108] Furthermore, according to this embodiment, the operating device 12 and the witness display device 13, which function as display devices, simultaneously display not only the measured result LXm2 but also the current position of the unmanned aerial vehicle 11 at the time the measured result LXm2 was obtained, which is more preferable.

[0109] Furthermore, in this embodiment, the measured result LXm2 presented by the operating device 12, which functions as a presentation device, is recorded by the pilot or assistant who receives the presentation by writing on recording paper. According to this embodiment, the measured result LXm2 and the current position of the unmanned aerial vehicle 11 at the time the measured result LXm2 was obtained are stored in the storage device 68 in a readable format. Later, the measured result and the current position of the unmanned aerial vehicle 11 at the time the measured result LXm2 was obtained can be read from the storage device 68 and compared with the measured result recorded by writing, thereby verifying the obtained measured result LXm2, and improving the reliability of the measurement.

[0110] In this embodiment, the measured result LXm2 and the current position of the unmanned aerial vehicle 11 at the time the measured result LXm2 was obtained are stored in the storage device 68 in a readable format. Therefore, the pilot or assistant who receives the measured result LXm2 may not record it by writing on recording paper, but may instead use the measured result LXm2 and the current position of the unmanned aerial vehicle 11 at the time the measured result LXm2 was obtained, read later from the storage device 68, as the final measured result. Even in this case, the possibility of errors can be reduced compared to recording by writing at the measurement site, thereby improving the reliability of the measurement. In this case, the measured result LXm2 read later from the storage device 68 can be input to the illuminance measurement result acquisition device 14, and the acquisition device 14 can calculate the measurement result LXm1.

[0111] Furthermore, according to this embodiment, the illuminance measurement result acquisition device 14 acquires the illuminance measurement result LXm1 at position P2, where the illuminance measurement result should be obtained, based on the actual illuminance measurement result LXm2 at the actual measurement position P2. Therefore, even if it is not possible to measure the illuminance at position P2 due to constraints on the movement of the unmanned aerial vehicle 11, the illuminance measurement result LXm1 at position P2 can be obtained with high accuracy.

[0112] [Second Embodiment]

[0113] Figure 11 is a schematic diagram showing an illuminance measurement system 101 according to a second embodiment of the present invention. Figure 12 is a schematic block diagram showing the assistant's display device 15 in Figure 11.

[0114] The difference between the illuminance measurement system 101 according to this embodiment and the illuminance measurement system 1 according to the first embodiment is that an assistant's display device 15 has been added.

[0115] The assistant's presentation device 15 is configured in basically the same way as the witness's presentation device 13, and has elements 111 to 120 that correspond to each of the elements 71 to 80 of the witness's presentation device 13.

[0116] The difference between the assistant's display device 15 and the witness's display device 13 is that, in autopilot mode, the CPU 111 of the assistant's display device 15 notifies the assistant of the timing (measurement timing) when a predetermined time has elapsed since the unmanned aircraft 11 came to rest at each measurement position (actual measurement position P2) by display on the display unit 117 or by sound. In this embodiment, in autopilot mode, the assistant, at the measurement timing, looks at the display image on the display unit 117, which is similar to the display image shown in Figure 10, and records the actual illuminance measured at the measurement position P (actual measurement position P2) by writing it on recording paper.

[0117] Furthermore, unlike the witness display device 13, in the assistant's display device 15, when in manual remote control mode, the assistant can see a display image on the display unit 117 similar to the display image shown in Figure 10, and use the operation unit 118 to indicate that the unmanned aircraft 11 has stopped at the desired measurement position and orientation and that the desired measurement timing has been reached.

[0118] According to this embodiment, in addition to obtaining the same advantages as the first embodiment, it is also possible to obtain the advantage of reducing the burden on the operator.

[0119] Although various embodiments of the present invention have been described above, the present invention is not limited to these embodiments.

[0120] For example, in each of the above embodiments, the CPU 61 of the operating device 12 recognizes the measured illuminance value from the display image of the display unit 44 of the illuminance meter 34 sent from the unmanned aircraft 11, and displays the recognized illuminance value in place of the image captured by the illuminance meter display unit imaging camera 35, which includes the display image 86a of the display unit 44 of the illuminance meter 34, in the display image shown in Figure 10 or in an image where the display area 88 is removed.

[0121] Furthermore, in each of the above embodiments, the ratio [LXth1 / LXth2] for each measurement position P is stored in advance in the storage device 68 of the operator 12 as a coefficient associated with the measurement position P for all measurement positions P. The CPU 61 of the operator 12 recognizes the measured illuminance value LXm2 from the display image of the display unit 44 of the illuminance meter 34 sent from the unmanned aerial vehicle 11. The CPU 61 of the operator 12 calculates the measured illuminance result LXm1 at position P1 by multiplying the recognized measured illuminance LXm2 by the coefficient (the value of the ratio [LXth1 / LXth2]). The operator 12 may also function as an illuminance measurement result acquisition device that automatically calculates the measured illuminance result LXm1. In this case, the illuminance measurement result LXm1 may be stored in the memory device 68 of the operator 12 in a readable format, or it may be displayed in addition to or in place of the measured illuminance LXm2 on the display unit 65 of the operator 12, the display unit 77 of the witness display device 13, or the display unit 117 of the assistant display device 15.

[0122] Furthermore, in each of the above embodiments, the CPU 21 of the unmanned aerial vehicle 11 recognizes the illuminance value, which is the measurement result, from the display image of the display unit 44 of the illuminance meter 34 captured by the illuminance meter display unit imaging camera 35, and sends the recognized illuminance value in real time to the operator 12 via wireless communication between the communication unit 27B and the communication unit 67B, instead of the captured display image, and displays the recognized illuminance value in the display image as shown in Figure 10, or in an image therefrom with the display area 88 removed, instead of the captured image 86 of the illuminance meter display unit imaging camera 35, which includes the display image 86a of the display unit 44 of the illuminance meter 34.

[0123] Furthermore, in each of the above embodiments, the ratio [LXth1 / LXth2] for each measurement position P is stored in the storage device 28 of the unmanned aerial vehicle 11 as a coefficient associated with the measurement position P for all measurement positions P. The CPU 21 of the unmanned aerial vehicle 11 recognizes the illuminance value, which is the measurement result, from the display image of the display unit 44 of the illuminance meter 34 captured by the illuminance meter display unit imaging camera 35. The CPU 21 of the unmanned aerial vehicle 11 calculates the illuminance measurement result LXm1 at position P1 by multiplying the recognized actual illuminance LXm2 by the coefficient (value of the ratio [LXth1 / LXth2]). Thus, the unmanned aerial vehicle 11 may be given the function of an illuminance measurement result acquisition device that automatically calculates the illuminance measurement result LXm1. In this case, the illuminance measurement result LXm1 may be stored in the memory device 28 of the unmanned aircraft 11 in a readable format, or it may be displayed via wireless communication on the display unit 65 of the control unit 12, the display unit 77 of the witness display device 13, or the display unit 117 of the assistant display device 15, in addition to or in place of the measured illuminance LXm2.

[0124] Furthermore, in the present invention, the embodiments and modifications described above may be appropriately modified to realize the illuminance measurement system according to each of the above-described aspects. For example, in the present invention, a display device is not necessarily required. [Explanation of symbols]
