[Modes for carrying out the invention]

[0008] <Issues this disclosure aims to address> Radar is also used for traffic monitoring at intersections, roads, etc. (hereinafter referred to as "infrastructure") for Radar (also called a "radar") is installed at intersections or on roads by construction workers, and the angle of the installed radar is adjusted by an adjustment specialist. At the time of installation by construction workers, the radar is not powered on, and furthermore, the construction workers do not have the knowledge to adjust the angle of the radar, making adjustment by the construction workers difficult. During the adjustment stage, the power is turned on to the installed radar, and the adjustment specialist adjusts the angle so that the irradiation axis is pointed in the appropriate direction while checking the output. However, the angles of radars installed by construction workers vary, and the optimal angle differs depending on the installation location, so adjustment is complicated, as it is sometimes necessary to remove the radar and reinstall it in order to adjust it correctly.

[0009] <Effects of this disclosure> According to this disclosure, it is possible to assist in adjusting the installation angle of radar for traffic monitoring.

[0010] <Summary of the embodiments of this disclosure> The embodiments of this disclosure are outlined below.

[0011] (1) The radar installation angle adjustment support device according to this embodiment includes a display device and a display control unit configured to display a support screen on the display device that assists in adjusting the installation angle of an infrastructure radar that detects objects in a target area by transmitting and receiving radio waves. The support screen includes a target value display unit configured to display a target value for the installation angle of the infrastructure radar, a detected angle display unit configured to display the installation angle detected by an angle sensor that detects the installation angle of the infrastructure radar, and a determination result display unit that displays a determination result of determining whether the angle difference between the target value displayed on the target value display unit and the installation angle displayed on the detected angle display unit falls within a predetermined setting range. If the angle difference falls outside the predetermined setting range, the display control unit displays the angle based on the angle difference on the support screen.

Therefore, it is possible to support the user in adjusting the installation angle of the infrastructure radar.

[0012] (2) The installation angle includes at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar, and the display control unit may cause at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar to be displayed on the detection angle display unit. This makes it possible to assist in adjusting at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar.

[0013] (3) The angle based on the angle difference may include an angle for correcting at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar. The display control unit may display the angle for correcting at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar on the support screen.

[0014] (4) The radar installation angle adjustment support device further includes a receiving unit configured to receive angle data indicating the angle detected by the angle sensor. Each time the angle data is received by the receiving unit, the display control unit updates the display of the angle based on the angle difference. When the angle difference changes so as to be included in the predetermined setting range, the display of the determination result display unit may be switched from the angle based on the angle difference to positive information indicating that the angle difference is included in the setting range. Thereby, the user can easily and appropriately adjust the installation angle by correcting the installation angle of the infrastructure radar until the display on the determination result display unit is switched from the angle based on the angle difference to positive information according to the support screen.

[0015] (5) The display color for displaying the angle based on the angle difference and the display color for displaying the positive information may be different from each other. Thereby, the user can easily confirm the switch from the angle based on the angle difference to the positive information on the determination result display unit.

[0016] (6) The support screen further includes an installation height display unit configured to display the installation height of the infrastructure radar. The display control unit may display the target value of the installation angle calculated based on the installation height displayed on the installation height display unit on the target value display unit. Thereby, an appropriate target value of the installation angle corresponding to the installation height of the infrastructure radar can be presented to the user.

[0017] (7) The support screen further includes an installation position information display unit configured to display installation position information indicating the installation position of the infrastructure radar, and a target position information display unit configured to display target position information indicating a target value of the radio wave irradiation position of the infrastructure radar. The display control unit may display the target value of the installation angle calculated based on the installation position information displayed on the installation position information display unit, the target position information displayed on the target position information display unit, and the installation height displayed on the installation height display unit on the target value display unit.

[0019] (9) The computer program according to this embodiment is a computer program that causes a computer equipped with a display device to perform a process to assist in adjusting the installation angle of an infrastructure radar that detects objects in a target area by transmitting and receiving radio waves, wherein the process includes causing the computer to display a support screen on the display device for assisting in adjusting the installation angle of the infrastructure radar, the support screen includes a target value display unit that displays a target value for the installation angle of the infrastructure radar, a detected angle display unit that displays the installation angle detected by an angle sensor that detects the installation angle of the infrastructure radar, and a determination result display unit that displays a determination result of determining whether the angle difference between the target value displayed on the target value display unit and the installation angle displayed on the detected angle display unit falls within a predetermined setting range, and if the angle difference falls outside the predetermined setting range, the angle based on the angle difference is displayed on the support screen. The user can adjust the installation angle of the infrastructure radar by checking the angle based on the angle difference on the support screen. Therefore, it is possible to assist the user in adjusting the installation angle of the infrastructure radar.

[0020] (10) The installation angle includes at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar, and the process of displaying the support screen on the display device may include displaying at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar on the detection angle display unit. This makes it possible to support the adjustment of at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar.

[0021] (11) The angle based on the angle difference includes an angle for correcting at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar, and the process of displaying the support screen on the display device may display the angle for correcting at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar on the support screen. This allows the user to appropriately correct at least one of the horizontal angle, depression angle, and roll angle of the infrastructure radar by checking the angle based on the angle difference.

[0022] (12) The process of displaying the support screen on the display device may include updating the display of the angle based on the angle difference each time angle data indicating the angle detected from the angle sensor is provided, and switching the display on the judgment result display unit from the angle based on the angle difference to positive information indicating that the angle difference is within the set range when the angle difference changes to fall within the predetermined set range. This allows the user to easily and appropriately adjust the installation angle of the infrastructure radar by correcting the installation angle of the infrastructure radar in accordance with the support screen until the display on the judgment result display unit switches from the angle based on the angle difference to positive information.

[0023] (13) The display color for displaying the angle based on the angle difference and the display color for displaying the positive information may be different from each other. This allows the user to easily confirm the switch from the angle based on the angle difference to the positive information in the judgment result display unit.

[0024] (14) The support screen further includes an installation height display unit that displays the installation height of the infrastructure radar, and the process of displaying the support screen on the display device may include displaying the target value of the installation angle calculated based on the installation height displayed on the installation height display unit on the target value display unit. This makes it possible to present the user with an appropriate target value for the installation angle according to the installation height of the infrastructure radar.

[0025] (15) The support screen further includes an installation location information display unit that displays installation location information indicating the installation location of the infrastructure radar, and a target location information display unit that displays target location information indicating the target value of the radio wave irradiation position of the infrastructure radar, and the process of displaying the support screen on the display device may include displaying the installation location information displayed on the installation location information display unit, the target location information displayed on the target location information display unit, and the target value of the installation angle calculated based on the installation height displayed on the installation height display unit, and the target value on the target value display unit. This makes it possible to present the user with the installation location of the infrastructure radar, the target value of the radio wave irradiation position of the infrastructure radar, and an appropriate target value of the installation angle according to the installation height of the infrastructure radar.

[0026] (16) The process of displaying the support screen on the display device may also involve displaying the installation location information, which indicates the position detected by the position sensor that detects the position of the infrastructure radar, on the installation location information display unit. This makes it possible to determine the target value of the installation angle of the infrastructure radar using the accurate installation location information of the infrastructure radar detected by the position sensor.

[0027] <Details of the embodiments of this disclosure> The embodiments of this disclosure will be described in detail below with reference to the drawings. At least some of the embodiments described below may be combined in any way.

[0028] (First Embodiment) [1-1. Radar] Figure 1 shows an example of the use of the radar according to this embodiment. The radar 100 according to this embodiment is a radio wave radar (infrastructure radar) for traffic monitoring. The radar 100 is attached to an arm 200 (see Figure 2) installed at an intersection or on a road. The radar 100 is a millimeter-wave radar and a radio wave sensor. The radar 100 detects objects (e.g., vehicles V) within the target area 300 by irradiating a target area 300 on the road with radio waves (millimeter waves) and receiving the reflected waves. More specifically, the radar 100 can detect the distance to a vehicle V traveling on the road, the speed of the vehicle V, and the horizontal angle of the position of the vehicle V with respect to the radar's radio wave irradiation axis.

[0029] Radar 100 is directed in the direction of the radio wave irradiation axis (shown by the dashed line in Figure 1). Direction The radar 100 is installed so that its reference direction (hereinafter referred to as the "reference direction") faces the target area 300. If the reference direction is not correctly oriented towards the target area 300, the radar 100 cannot accurately detect objects within the target area 300. For this reason, in this embodiment, the angle of the radar 100 is adjusted using a radar installation angle adjustment support device as described below so that the reference direction faces the target area 300.

[0030] Figure 2 is a perspective view showing an example of the external configuration of the radar 100 according to the first embodiment. As shown in Figure 2, the radar 100 has a transmitting / receiving surface 101 for transmitting and receiving millimeter waves. The reference direction is the normal direction of the transmitting / receiving surface 101. The radar 100 incorporates at least one transmitting antenna and a plurality (e.g., two) receiving antennas, which are not shown. The radar 100 transmits a modulated wave, which is a millimeter wave, from the transmitting antenna through the transmitting / receiving surface 101. The modulated wave strikes an object and is reflected, and the receiving antenna receives the reflected wave. The radar 100 performs signal processing on the transmitted wave signal and the received wave signal using a signal processing circuit (not shown) to detect the distance to the object, the angle at which the object is located (hereinafter referred to as "the position of the object"), and the velocity of the object.

[0031] The radar 100 is configured to allow adjustment of its installation angle. The radar 100 includes a radar body 102, a depression angle adjustment unit 103, a horizontal angle adjustment unit 104, and a roll angle adjustment unit 105. The radar body 102 is box-shaped, and the depression angle adjustment unit 103 is attached to the side of the radar body 102. The depression angle adjustment unit 103 includes a pair of arms 103a and a connecting unit 103b that connects the pair of arms 103a. Each of the pair of arms 103a is rotatable on both sides of the radar body 102 about a horizontal axis parallel to the transmitting / receiving surface 101. The radar body 102 is rotatable about the horizontal axis by the depression angle adjustment unit 103, thereby adjusting the depression angle of the radar body 102.

[0032] The connecting portion 103b is connected to the roll angle adjustment portion 105. The roll angle adjustment portion 105 includes a lower member 105a and an upper member 105b, and the lower member 105a and the upper member 105b are rotatable relative to each other about a horizontal rotation axis that extends in a direction perpendicular to the longitudinal direction of the connecting portion 103b. The lower member 105a is fixed to the upper surface of the connecting portion 103b. The radar body 102, which is connected to the roll angle adjustment portion 105 via the depression angle adjustment portion 103, is rotatable about the horizontal rotation axis by the roll angle adjustment portion 105, thereby adjusting the roll angle of the radar body 102.

[0033] The upper member 105b of the roll angle adjustment unit 105 is connected to the horizontal angle adjustment unit 104. The horizontal angle adjustment unit 104 is fixed to the pole to be installed. The horizontal angle adjustment unit 104 is rotatable about the vertical axis on the upper surface of the upper member 105b. The radar body 102, which is connected to the horizontal angle adjustment unit 104 via the depression angle adjustment unit 103 and the roll angle adjustment unit 105, is rotatable about the vertical axis by the horizontal angle adjustment unit 104, thereby adjusting the horizontal angle of the radar body 102.

[0034] The radar unit 102 is equipped with an angle sensor 150. The angle sensor 150 can detect the horizontal angle, depression angle, and roll angle of the radar unit 102. As shown in Figure 3, the angle sensor 150 is connected to the radar installation angle adjustment support device 400 by wire or wireless. The detected value (angle) data from the angle sensor 150 (hereinafter referred to as "angle data") is transmitted to the radar installation angle adjustment support device 400. The radar installation angle adjustment support device 400 can display a support screen on a display device that includes the horizontal angle, depression angle, and roll angle detected by the angle sensor 150. The support screen includes target values ​​for the horizontal angle, depression angle, and roll angle of the radar 100. The user can adjust the angle of the radar 100 while checking the support screen.

[0035] [1-2. Configuration of the radar installation angle adjustment support device] Figure 3 is a block diagram showing an example of the configuration of a radar installation angle adjustment support device according to the first embodiment. The radar installation angle adjustment support device 400 is composed of a portable information terminal such as a smartphone, tablet, or portable computer. The radar installation angle adjustment support device 400 includes a processor 401, a non-volatile memory 402, a volatile memory 403, a graphics controller 404, a display device 405, an input device 406, and a communication interface (communication I / F) 407.

[0036] The volatile memory 403 is a semiconductor memory such as SRAM (Static Random Access Memory) or DRAM (Dynamic Random Access Memory). The non-volatile memory 402 is a flash memory, hard disk, ROM (Read Only Memory), etc. The non-volatile memory 402 stores the angle adjustment support program 409, which is a computer program, and the data used to execute the angle adjustment support program 409. The radar installation angle adjustment support device 400 is configured with a computer, and each function of the radar installation angle adjustment support device 400 is performed by the execution of the angle adjustment support program 409, which is a computer program stored in the storage device of the computer, by the processor 401. The angle adjustment support program 409 can be stored in a recording medium such as flash memory, ROM, or CD-ROM. The processor 401 is the angle adjustment support program Execute 409 to display a support screen on the display device 405, as described later.

[0037] The processor 401 is, for example, a CPU (Central Processing Unit). However, the processor 401 is not limited to a CPU. The processor 401 may also be a GPU (Graphics Processing Unit). The processor 401 may also be, for example, an ASIC (Application Specific Integrated Circuit), or a programmable logic device such as a gate array or FPGA (Field Programmable Gate Array). In this case, the ASIC or programmable logic device is configured to perform processing similar to that of the angle adjustment support program 409.

[0038] The graphics controller 404 is an example of a display control unit. The graphics controller 404 is connected to the display device 405 and controls the display on the display device 405. The graphics controller 404 includes, for example, a GPU and VRAM (Video RAM), stores data to be displayed on the display device 405 in VRAM, periodically reads one frame of video data from VRAM, and generates a video signal. The generated video signal is output to the display device 405, and the video is displayed on the display device 405. The functions of the graphics controller 404 may also be included in the processor 401. A portion of the volatile memory 403 may be used as VRAM.

[0039] The display device 405 includes, for example, a liquid crystal panel or an OEL (organic electroluminescent) panel. The display device 405 can display character or graphic information. The input device 406 includes, for example, a capacitive or pressure-sensitive touchpad superimposed on the display device 405. The input device 406 may also be a pointing device such as a keyboard and mouse. The input device 406 is used to input information to the radar installation angle adjustment support device 400.

[0040] The communication interface 407 can communicate with external devices via wired or wireless connection. The communication interface 407 can receive angle data transmitted from the angle sensor 150.

[0041] [1-3. Operation of the radar installation angle adjustment support device] Figure 4 is a flowchart showing an example of the operation procedure of the radar installation angle adjustment support device 400 according to the first embodiment. When the processor 401 starts the angle adjustment support program 409, the radar installation angle adjustment support device 400 performs the operations described below.

[0042] The processor 401 causes the display device 405 to display an assistance screen to help adjust the installation angle of the radar 100 (step S101).

[0043] Figures 5A and 5B show examples of support screens according to the first embodiment. As shown in Figures 5A and 5B, the support screen 500 includes a target value input unit 510, a detection angle display unit 520, and a judgment result display unit 530.

[0044] The target value input unit 510 is an area for inputting target values ​​for the installation angles (horizontal angle, depression angle, and roll angle) of the radar 100. The target value input unit 510 includes a target value display unit 511 and a tolerance range display unit 512.

[0045] The target value display unit 511 is an area for displaying the target value of the installation angle of the radar 100. The target value display unit 511 includes input boxes for horizontal angle, depression angle, and roll angle. The user can input the target values ​​for the horizontal angle, depression angle, and roll angle into each input box. The input target values ​​for the horizontal angle, depression angle, and roll angle are displayed in each input box.

[0046] The tolerance range display unit 512 is an area for displaying the tolerance range (set range) within which the radar's installation angle can deviate from the target value. The tolerance range display unit 512 includes input boxes for the tolerance ranges of the horizontal angle, depression angle, and roll angle. The user can input the tolerance ranges for the horizontal angle, depression angle, and roll angle into each input box. The input tolerance ranges for the horizontal angle, depression angle, and roll angle are displayed in each input box.

[0047] In the target value display unit 511, the input boxes for the target values ​​of the horizontal angle, depression angle, and roll angle are arranged in order vertically. In the tolerance range display unit 512, the input boxes for the tolerance ranges of the horizontal angle, depression angle, and roll angle are arranged in order vertically. This prevents users from confusing the input boxes for the target values ​​of the horizontal angle, depression angle, and roll angle with the input boxes for the tolerance ranges of the horizontal angle, depression angle, and roll angle. The predetermined order of the input boxes for the target values ​​of the horizontal angle, depression angle, and roll angle prevents users from confusing the input boxes for the target values ​​of the horizontal angle, depression angle, and roll angle. The predetermined order of the input boxes for the tolerance ranges of the horizontal angle, depression angle, and roll angle prevents users from confusing the input boxes for the tolerance ranges of the horizontal angle, depression angle, and roll angle. Furthermore, in the target value display unit 511 and the tolerance range display unit 512, the order of the input boxes for horizontal angle, depression angle, and roll angle is unified, making it easy for the user to remember this order and to easily input and confirm the target values ​​and tolerance ranges for each of the horizontal angle, depression angle, and roll angle.

[0048] The target value display unit 511 and the tolerance range display unit 512 are positioned adjacent to each other horizontally. The input box for the target value of the horizontal angle in the target value display unit 511 and the input box for the tolerance range of the horizontal angle in the tolerance range display unit 512 are positioned adjacent to each other horizontally. The input box for the target value of the depression angle in the target value display unit 511 and the input box for the tolerance range of the depression angle in the tolerance range display unit 512 are positioned adjacent to each other horizontally. The input box for the target value of the roll angle in the target value display unit 511 and the input box for the tolerance range of the roll angle in the tolerance range display unit 512 are positioned adjacent to each other horizontally. This allows the user to easily input and confirm the target values ​​and tolerance ranges for the horizontal angle, depression angle, and roll angle, respectively, in association with each other.

[0049] Refer to Figure 4 again. The user inputs the target values ​​and tolerance ranges for the installation angles (horizontal angle, depression angle, and roll angle) of the radar 100 into the target value input unit 510. The radar installation angle adjustment support device 400 accepts the target values ​​and tolerance ranges for the installation angles of the radar 100 (step S102).

[0050] The angle sensor 150 detects the horizontal angle, depression angle, and roll angle of the radar 100 and transmits angle data. The radar installation angle adjustment support device 400 receives the angle data from the angle sensor 150 (step S103). The received detected angles are displayed on the detected angle display unit 520 on the support screen 500.

[0051] Refer again to Figures 5A and 5B. The detection angle display unit 520 is an area for displaying the angles (horizontal angle, depression angle, and roll angle) detected by the angle sensor 150 provided on the installed radar 100. The detection angle display unit 520 includes display boxes for the horizontal angle, depression angle, and roll angle. The detected angles of the horizontal angle, depression angle, and roll angle by the angle sensor 150 are displayed in each display box.

[0052] In the detection angle display unit 520, the display boxes for the detection angles of the horizontal angle, depression angle, and roll angle are arranged in a vertical order. By having a fixed order for the display boxes for the detection angles of the horizontal angle, depression angle, and roll angle, it is possible to prevent users from confusing the detection angles of the horizontal angle, depression angle, and roll angle. Furthermore, because the order of the display boxes for the detection angles of the horizontal angle, depression angle, and roll angle in the detection angle display unit 520 is the same as the order of the input boxes for the target values ​​of the horizontal angle, depression angle, and roll angle in the target value display unit 511, it is easier for users to remember this order and to easily check the target values ​​and detection angles for the horizontal angle, depression angle, and roll angle.

[0053] The target value input unit 510 and the detection angle display unit 520 are positioned adjacent to each other horizontally. The input boxes for the target value and tolerance range of the horizontal angle in the target value input unit 510 and the display box for the detection angle of the horizontal angle in the detection angle display unit 520 are positioned adjacent to each other horizontally (i.e., at the same height). The input boxes for the target value and tolerance range of the depression angle in the target value input unit 510 and the display box for the detection angle of the depression angle in the detection angle display unit 520 are positioned adjacent to each other horizontally. The input boxes for the target value and tolerance range of the roll angle in the target value input unit 510 and the display box for the detection angle of the roll angle in the detection angle display unit 520 are positioned adjacent to each other horizontally. This makes it easy for the user to compare the target values ​​and tolerance ranges for the horizontal angle, depression angle, and roll angle with the detected angles for the horizontal angle, depression angle, and roll angle.

[0054] Refer to Figure 4 again. The processor 401 calculates the difference (angle difference) between the target values ​​for the horizontal angle, depression angle, and roll angle given by the user and the detected values ​​for the horizontal angle, depression angle, and roll angle detected by the angle sensor 150 (step S104).

[0055] The processor 401 determines whether the angle differences calculated for the horizontal angle, depression angle, and roll angle are within the acceptable range (step S105). If the angle difference for any of the horizontal angle, depression angle, and roll angle exceeds the acceptable range, that is, if the determination result is negative (NO in step S105), the processor 401 displays correction information for correcting the installation angle of the radar 100 (angles based on the angle difference between the installation angle of the radar 100 and the target value of the installation angle) on the determination result display unit 530 on the support screen 500 (step S106).

[0056] Refer again to Figures 5A and 5B. The judgment result display unit 530 is an area for displaying the judgment result, which determines whether the difference (angle difference) between the target value displayed in the target value display unit 511 and the angle displayed in the detection angle display unit 520 falls within the acceptable range. The judgment result display unit 530 is arranged vertically alongside the target value input unit 510 and the detection angle display unit 520. In the example of Figures 5A and 5B, the judgment result display unit 530 is positioned above the target value input unit 510 and the detection angle display unit 520. Note that the arrangement of the target value input unit 510, the detection angle display unit 520, and the judgment result display unit 530 is not limited to this arrangement; for example, the judgment result display unit 530 may be positioned below the target value input unit 510 and the detection angle display unit 520.

[0057] The allowable range is an example of a predetermined setting range. The setting range does not have to be a range determined by the user. For example, the setting range may be a range that is fixed in advance to the radar installation angle adjustment support device 400, or it may be a range transmitted from a server or information terminal connected to the radar installation angle adjustment support device 400 via a communication network.

[0058] Figure 5A shows an example where a negative judgment result is displayed on the judgment result display unit 530. If the judgment result is negative, correction information 531 is displayed on the judgment result display unit 530. The correction information 531 is information generated based on the calculated angle difference. The correction information 531 includes the direction and amount of correction for at least one of the horizontal angle, depression angle, and roll angle of the radar 100. In the example in Figure 5A, the target value for the horizontal angle is 130°, while the detected angle for the horizontal angle is 127°, resulting in an angle difference of 3°. Since the tolerance range for the horizontal angle is ±1°, the angle difference exceeds the tolerance range. The target value for the depression angle is 5°, while the detected angle for the depression angle is 4°, resulting in an angle difference of 1°. Since the tolerance range for the depression angle is ±1°, the angle difference is within the tolerance range. The target value for the roll angle is 0°, while the detected angle for the roll angle is -1.2°, resulting in an angle difference of -1.2°. Since the allowable range for the roll angle is ±1°, the angle difference exceeds the allowable range. Correction information 531 includes the text information "Insufficient adjustment" indicating that the angle adjustment is not complete, and the text information "Tilt the radar 3° to the left, 1° downward, and 1.2° clockwise" indicating the direction and amount of correction to be made to the radar angle. Such correction information is generated based on the angle differences of 3°, 1°, and -1.2° for the horizontal angle, depression angle, and roll angle, respectively. The user can correct the installation angle of the radar 100 according to correction information 531.

[0059] Refer to Figure 4 again. After the processor 401 displays the correction information 531 on the judgment result display unit 530, it returns to step S103. As a result, each time angle data is received by the communication I / F 407, the angle difference between the target value and the detected angle for the horizontal angle, depression angle, and roll angle is calculated, and it is determined whether or not the angle difference falls within the acceptable range. If the judgment result is negative, the correction information on the judgment result display unit 530 is updated.

[0060] If all angle differences, including the horizontal angle, downward angle, and roll angle, fall within the acceptable range, that is, if the judgment result is positive (YES in step S105), the processor 401 displays positive information indicating that the angle differences fall within the acceptable range on the judgment result display unit 530 on the support screen 500 (step S107).

[0061] Refer again to Figure 5B. Figure 5B shows an example in which a positive judgment result is displayed on the judgment result display unit 530. If the judgment result is positive, positive information 532 is displayed on the judgment result display unit 530. Positive information 532 is information to notify the user that the angle adjustment is complete. The display color of positive information 532 is different from the display color of correction information 531. For example, the display color of correction information 531 is red, and the display color of positive information 532 is green. Because the display color of positive information 532 is different from the display color of correction information 531, the user can easily recognize that the display on the judgment result display unit 530 has switched from correction information 531 to positive information 532.

[0062] In the example in Figure 5B, the target value for the horizontal angle is 130°, while the detected horizontal angle is 129°, resulting in an angle difference of 1°. Since the tolerance range for the horizontal angle is ±1°, the angle difference is within the tolerance range. The target value for the depression angle is 5°, while the detected depression angle is 4°, resulting in an angle difference of 1°. Since the tolerance range for the depression angle is ±1°, the angle difference is within the tolerance range. The target value for the roll angle is 0°, while the detected roll angle is -0.2°, resulting in an angle difference of -0.2°. Since the tolerance range for the roll angle is ±1°, the angle difference is within the tolerance range. The affirmative information 532 includes the text information "OK" indicating that the angle adjustment is complete, and the text information "Within tolerance range" indicating that the angle difference is within the tolerance range. By confirming the affirmative information 532, the user can recognize that the adjustment of the installation angle of the radar 100 is complete.

[0063] This concludes the operation of the radar installation angle adjustment support device 400.

[0064] (Second Embodiment) [2-1. Radar] Figure 6 is a perspective view showing an example of the external configuration of the radar 100 according to the second embodiment. As shown in Figure 6, the radar body 102 is equipped not only with an angle sensor 150 but also with a GNSS (Global Navigation Satellite System) receiver 160. The GNSS receiver 160 is an example of a position sensor. The GNSS receiver 160 receives information transmitted from multiple artificial satellites and acquires position information (hereinafter referred to as "installation position information") of the GNSS receiver 160 (i.e., the radar 100 to which the GNSS receiver 160 is attached) based on the received information. The configuration of the radar 100 according to this embodiment is the same as that of the radar 100 according to the first embodiment, so the same reference numerals are used for the same components and their descriptions are omitted.

[0065] [2-2. Configuration of the Radar Installation Angle Adjustment Support Device] Figure 7 is a block diagram showing an example of the configuration of a radar installation angle adjustment support device according to the second embodiment. In the radar installation angle adjustment support device 400 according to the second embodiment, the communication I / F 407 communicates not only with the angle sensor 150 but also with the GNSS receiver 160. The communication I / F 407 can receive installation position information from the GNSS receiver 160. The configuration of the radar installation angle adjustment support device 400 according to this embodiment is the same as the configuration of the radar installation angle adjustment support device 400 according to the first embodiment, so the same reference numerals are used for the same components and their descriptions are omitted.

[0066] [2-3. Operation of the radar installation angle adjustment support device] Figure 8 is a flowchart showing an example of the operation procedure of the radar installation angle adjustment support device 400 according to the second embodiment. When the processor 401 starts the angle adjustment support program 409, the radar installation angle adjustment support device 400 performs the operations described below.

[0067] The processor 401 causes the display device 405 to display an assistance screen to help adjust the installation angle of the radar 100 (step S201).

[0068] Figures 9A and 9B show examples of support screens according to the second embodiment. As shown in Figures 9A and 9B, the support screen 600 includes a target position information display unit 610, an installation height display unit 620, a radar angle information display unit 630, an installation position information display unit 640, and a judgment result display unit 650.

[0069] The target position information display unit 610 is an area for inputting target position information indicating the target value of the radar 100's radio wave irradiation position and for displaying the input target position information. The radio wave irradiation position is the intersection point of the radar 100's radio wave irradiation axis and the Earth's surface. The target position information is, for example, absolute position information and includes latitude and longitude. The target position information display unit 610 includes input boxes for inputting latitude and longitude, respectively. The user can input the latitude and longitude of the target value of the radio wave irradiation position into each input box. The input latitude and longitude are displayed in each input box.

[0070] The installation height display unit 620 is an area for inputting the installation height of the radar 100 and displaying the entered installation height. The installation height of the radar 100 is the height from the ground surface at the installation location of the radar 100. The installation height display unit 620 includes an input box for inputting the installation height. The user can input the installation height into the input box. The entered installation height is displayed in the input box.

[0071] In this embodiment, the target position information display unit 610 and the installation height display unit 620 are arranged vertically side by side in the left-hand area of ​​the support screen 600. The installation height display unit 620 is positioned below the target position information display unit 610.

[0072] Refer to Figure 8 again. The user inputs the target values ​​(latitude and longitude) of the radar 100's radio wave irradiation position into the target position information display unit 610 and the installation height of the radar 100 into the installation height display unit 620. The radar installation angle adjustment support device 400 receives the target values ​​of the radar 100's radio wave irradiation position (step S202) and the installation height (step S203).

[0073] The GNSS receiver 160 acquires the installation location information of the radar 100 and transmits the installation location information. The installation location information includes latitude and longitude. The radar installation angle adjustment support device 400 receives the installation location information from the GNSS receiver 160 (step S204). The received installation location information is displayed on the installation location information display unit 640 on the support screen 500.

[0074] Refer again to Figures 9A and 9B. The installation location information display unit 640 is an area for displaying the installation location information (latitude and longitude) of the radar 100. The installation location information display unit 640 includes display boxes for latitude and longitude. The latitude and longitude acquired by the GNSS receiver 160 are displayed in each display box.

[0075] In this embodiment, the installation height display unit 620 and the installation position information display unit 640 are arranged side by side horizontally in the lower area of ​​the support screen 600. The installation position information display unit 640 is positioned to the right of the installation height display unit 620.

[0076] Refer to Figure 8 again. The processor 401 determines target values ​​for the installation angles (horizontal angle, depression angle, and roll angle) of the radar 100 based on the target values ​​(latitude and longitude) of the radio wave irradiation position given by the user, the installation position information (latitude and longitude) of the radar 100 given by the GNSS receiver 160, and the installation height of the radar 100 given by the user (step S205). That is, the distance from the installation position of the radar 100 to the target radio wave irradiation position is determined based on the target values ​​of the radio wave irradiation position and the installation position information of the radar 100 detected by the GNSS receiver 160. Based on the calculated distance and the installation height of the radar 100, the target value for the installation angle of the radar 100 is determined. For example, a correspondence table showing the relationship between the distance from the installation position of radar 100 to the target radio wave irradiation position, the installation height of radar 100, and the target value of the installation angle of radar 100 is stored in the non-volatile memory 402, and the processor 401 can determine the target value of the installation angle of radar 100 by referring to the correspondence table. In another example, the processor 401 may calculate the target value of the installation angle of radar 100 from the distance from the installation position of radar 100 to the target radio wave irradiation position and the installation height of radar 100. The determined target value of the installation angle is displayed on the radar angle information display unit 630 of the support screen 600.

[0077] Refer again to Figures 9A and 9B. In this embodiment, the target position information display unit 610 and the radar angle information display unit 630 are arranged side by side horizontally in the area of ​​the vertical center of the support screen 600. The radar angle information display unit 630 is positioned to the right of the target position information display unit 610. Furthermore, the radar angle information display unit 630 and the installation position information display unit 640 are displayed side by side vertically in the area on the right side of the support screen 600. The radar angle information display unit 630 is positioned above the installation position information display unit 640.

[0078] The radar angle information display unit 630 includes a target value display unit 631 and a detection angle display unit 632. The target value display unit 631 is an area for displaying the target value of the installation angle of the radar 100. The target value display unit 631 includes display boxes for the horizontal angle, depression angle, and roll angle. The determined target values ​​for the horizontal angle, depression angle, and roll angle are displayed in their respective display boxes.

[0079] In the target value display unit 631, the display boxes for the target values ​​of the horizontal angle, depression angle, and roll angle are arranged in a vertical order. By defining the order of the display boxes for the target values ​​of the horizontal angle, depression angle, and roll angle, it is prevented for the user from confusing the display boxes for the target values ​​of the horizontal angle, depression angle, and roll angle.

[0080] Refer to Figure 8 again. The angle sensor 150 detects the horizontal angle, depression angle, and roll angle of the radar 100 and transmits angle data. The radar installation angle adjustment support device 400 receives the angle data from the angle sensor 150 (step S206). The received detected angles are displayed on the detected angle display unit 632 on the support screen 600.

[0081] Refer again to Figures 9A and 9B. The detection angle display unit 632 is an area for displaying the angles (horizontal angle, depression angle, and roll angle) detected by the angle sensor 150 provided on the installed radar 100. The detection angle display unit 632 includes display boxes for the horizontal angle, depression angle, and roll angle. The detected angles of the horizontal angle, depression angle, and roll angle by the angle sensor 150 are displayed in each display box.

[0082] In the detection angle display unit 632, the display boxes for the detection angles of the horizontal angle, depression angle, and roll angle are arranged in a vertical order. By having a fixed order for the display boxes for the detection angles of the horizontal angle, depression angle, and roll angle, it is possible to prevent users from confusing the detection angles of the horizontal angle, depression angle, and roll angle. Furthermore, because the order of the display boxes for the detection angles of the horizontal angle, depression angle, and roll angle in the detection angle display unit 632 is the same as the order of the input boxes for the target values ​​of the horizontal angle, depression angle, and roll angle in the target value display unit 631, it is easier for users to remember this order and to easily check the target values ​​and detection angles for the horizontal angle, depression angle, and roll angle.

[0083] The target value display unit 631 and the detection angle display unit 632 are positioned adjacent to each other horizontally. The display box for the target value of the horizontal angle in the target value display unit 631 and the display box for the detection angle of the horizontal angle in the detection angle display unit 632 are positioned adjacent to each other horizontally (i.e., at the same height). The display box for the target value of the depression angle in the target value display unit 631 and the display box for the detection angle of the depression angle in the detection angle display unit 632 are positioned adjacent to each other horizontally. The display box for the target value of the roll angle in the target value display unit 631 and the display box for the detection angle of the roll angle in the detection angle display unit 632 are positioned adjacent to each other horizontally. This makes it easy for the user to compare the target values ​​of the horizontal angle, depression angle, and roll angle with the detected angles of the horizontal angle, depression angle, and roll angle.

[0084] Refer to Figure 8 again. The processor 401 calculates the difference between the target values ​​for the horizontal angle, depression angle, and roll angle provided by the user and the detected values ​​for the horizontal angle, depression angle, and roll angle detected by the angle sensor 150 (step S207).

[0085] The processor 401 determines whether the angle differences calculated for the horizontal angle, depression angle, and roll angle fall within the acceptable range (step S208). In this embodiment, the acceptable range is not input by the user to the radar installation angle adjustment support device 400, but is pre-stored in the non-volatile memory 402. If the angle difference for any of the horizontal angle, depression angle, and roll angle exceeds the acceptable range, that is, if the determination result is negative (NO in step S208), the processor 401 displays correction information for correcting the installation angle of the radar 100 on the determination result display unit 650 on the support screen 600 (step S209).

[0086] Refer again to Figures 9A and 9B. The judgment result display unit 650 is an area for displaying the judgment result, which determines whether the difference (angle difference) between the target value displayed in the target value display unit 631 and the angle displayed in the detection angle display unit 632 falls within the acceptable range. In the example of Figures 9A and 9B, the judgment result display unit 650 is positioned above the target position information display unit 610 and the radar angle information display unit 630. Note that the positional relationship between the target position information display unit 610, the installation height display unit 620, the radar angle information display unit 630, the installation position information display unit 640, and the judgment result display unit 650 on the support screen 600 is not limited to that described in this embodiment.

[0087] Figure 9A shows an example where a negative judgment result is displayed on the judgment result display unit 650. When the judgment result is negative, correction information 651 is displayed on the judgment result display unit 650. Since the correction information 651 is the same as the correction information 531 described in the first embodiment, its explanation is omitted.

[0088] Refer to Figure 8 again. After the processor 401 displays the correction information 651 on the judgment result display unit 650, it returns to step S206. As a result, each time angle data is received by the communication I / F 407, the angle difference between the target value and the detected angle for the horizontal angle, depression angle, and roll angle is calculated, and it is determined whether or not the angle difference falls within the acceptable range. If the judgment result is negative, the correction information on the judgment result display unit 650 is updated.

[0089] If all angle differences, including the horizontal angle, downward angle, and roll angle, fall within the acceptable range, that is, if the judgment result is positive (YES in step S208), the processor 401 displays positive information indicating that the angle differences fall within the acceptable range on the judgment result display unit 650 on the support screen 600 (step S210).

[0090] Refer to Figure 9B again. Figure 9B shows the result display section for positive judgment results. 650 An example of what is displayed is shown. If the judgment result is positive, the judgment result display unit 650 displays positive information 652. The positive information 652 is the positive information described in the first embodiment. 532 Since it is the same as before, the explanation will be omitted.

[0091] This concludes the operation of the radar installation angle adjustment support device 400.

[0092] [3. Change shape example] In the second embodiment, the target value of the installation angle of the radar 100 was determined based on the target value of the radar 100's radio wave irradiation position, the installation position of the radar 100, and the installation height of the radar 100, but the embodiment is not limited to this. The target value of the installation angle of the radar 100 may also be determined based on the installation height of the radar 100. That is, the distance from the installation position of the radar 100 to the target radio wave irradiation position may be set as a predetermined value, the installation height of the radar 100 may be received by the radar installation angle adjustment support device 400 from the user or server, and the target value of the installation angle of the radar 100 may be determined based on the given installation height. For example, a correspondence table showing the correspondence between the installation height of the radar 100 and the target value of the installation angle of the radar 100 is stored in the non-volatile memory 402, and the processor 401 can refer to the correspondence table to identify the target value of the installation angle corresponding to the installation height of the radar 100.

[0093] [4. Effects] The radar installation angle adjustment support device 400 according to the embodiment includes a display device 405 and a graphic controller 404. The graphic controller 404 causes the display device 405 to display support screens 500 and 600 that support the adjustment of the installation angle of the radar 100. The support screens 500 and 600 include target value display units 511 and 631, detection angle display units 520 and 632, and determination result display units 530 and 650. The target value display units 511 and 631 are configured to display the target value of the installation angle of the radar 100. The detection angle display units 520 and 632 are configured to display the installation angle detected by the angle sensor 150 that detects the installation angle of the radar 100. The judgment result display units 530 and 650 are configured to display a judgment result determining whether the angle difference between the target value displayed in the target value display units 511 and 631 and the angle displayed in the detection angle display units 520 and 632 falls within an acceptable range (a predetermined set range). If the angle difference falls outside the acceptable range, the graphics controller 404 displays correction information 531 and 651 (angle based on the angle difference) in the judgment result display units 530 and 650. The correction information 531 and 651 is information for correcting the installation angle of the radar 100. The user can adjust the installation angle of the radar 100 by checking the correction information 531 and 651 on the support screens 500 and 600. Therefore, it is possible to support the user in adjusting the installation angle of the radar 100.

[0094] The installation angle of the radar 100 may include at least one of the horizontal angle, depression angle, and roll angle of the radar 100. The graphics controller 404 may display at least one of the horizontal angle, depression angle, and roll angle of the radar 100 on the detection angle display units 520 and 632. This can assist in adjusting at least one of the horizontal angle, depression angle, and roll angle of the radar 100.

[0095] Correction information 531,651 may include an angle for correcting at least one of the horizontal angle, depression angle, and roll angle of the radar 100. The graphics controller 404 may display the angle for correcting at least one of the horizontal angle, depression angle, and roll angle of the radar 100 on the support screens 500,600. This allows the user to appropriately correct at least one of the horizontal angle, depression angle, and roll angle of the radar 100 by checking the correction information.

[0096] The radar installation angle adjustment support device 400 may further include a communication I / F (receiving unit) 407. The communication I / F 407 is configured to receive angle data indicating the angle detected by the angle sensor 150. The graphic controller 404 updates the display of correction information 531,651 each time angle data is received by the communication I / F 407, and may switch the display of the judgment result display unit 530,650 from correction information 531,651 to positive information 532,652 when the angle difference changes to fall within the acceptable range. The positive information 532,652 indicates that the angle difference falls within the acceptable range. This allows the user to easily and appropriately adjust the installation angle by correcting the installation angle of the radar 100 according to the support screens 500,600 until the display on the judgment result display unit 530,650 switches from correction information 531,651 to positive information 532,652.

[0097] The display colors for displaying the correction information 531 and 651 and the display colors for displaying the positive information 532 and 652 may be different from each other. This allows the user to easily confirm the switch from the correction information 531 and 651 to the positive information 532 and 652 in the judgment result display units 530 and 650.

[0098] The support screen 600 may further include an installation height display unit 620. The installation height display unit 620 is configured to display the installation height of the radar 100. The graphics controller 404 may display the target value of the installation angle calculated based on the installation height displayed on the installation height display unit 620 on the target value display units 511 and 631. This makes it possible to present the user with an appropriate target value for the installation angle according to the installation height of the radar 100.

[0099] The support screen 600 may further include an installation location information display unit 640 and a target location information display unit 610. The installation location information display unit 640 is configured to display installation location information indicating the installation location of the radar 100. The target location information display unit 610 is configured to display target location information indicating the target value of the radar 100's radio wave irradiation position. The graphics controller 404 may cause the target value of the installation angle calculated based on the installation location information displayed on the installation location information display unit 640, the target location information displayed on the target location information display unit 610, and the installation height displayed on the installation height display unit 620 to be displayed on the target value display units 511 and 631. This makes it possible to present the user with the installation location of the radar 100, the target value of the radar 100's radio wave irradiation position, and an appropriate target value of the installation angle according to the installation height of the radar 100.

[0100] The graphics controller 404 may display installation location information, which indicates the position detected by the GNSS receiver 160 that detects the position of the radar 100, on the installation location information display unit 640. This allows the target value of the installation angle of the radar 100 to be calculated using the accurate installation location information of the radar 100 detected by the GNSS receiver 160.
