[Figure 8] This is an explanatory diagram showing a method for playing back and saving recorded data of one embodiment of the present invention. [Modes for carrying out the invention]

[0012] A preferred embodiment of the present invention will be described with reference to the accompanying drawings. Note that not all of the configurations described below are essential requirements of the present invention.

[0013] FIG. 1 shows a monitoring system for a self-propelled cart according to an embodiment of the present invention. The golf cart 1, which is a self-propelled cart, includes a vehicle body 2, four wheels 3, a seat 4 on which a passenger sits, a steering device 5 for performing a driving operation, and a roof portion 6. A golf bag 7 can be loaded behind the seat 4. The self-propelled cart in the present embodiment refers to one that can travel by the power provided by the cart itself without relying on external power. Therefore, it includes not only those operated (including remote operation) by a person but also those that perform automatic driving.

[0014] As shown in FIGS. 1 and 2, the information terminal 8 has a display unit 9 capable of displaying various images, videos, etc., a touch panel type operation unit 10, an out-camera 12 (front camera), which is a photographing means provided on the rear surface portion 11 of the information terminal 8, and an in-camera 14 (rear camera), which is a photographing means provided on the front surface portion 13 of the information terminal 8.

[0015] The information terminal 8 is attached to the roof portion 6. The attachment position of the information terminal 8 may be other positions as long as the out-camera 12 and the in-camera 14 can photograph the front, rear, and inside of the golf cart 1. FIG. 1 shows an embodiment in which the information terminal 8 is fixed to the roof portion 6, but as will be described later, an angle adjuster 28 for adjusting the orientation and angle of the information terminal 8 may be used. <(

[0016] The information terminal 8 can perform two-way wireless communication with the management server 15 (cloud) via the Internet. Also, the management personal computer 16 installed at the golf course can also communicate with the management server 15 in both directions via the Internet. Note that the information terminal 8 and the management personal computer 16 may be able to communicate with each other in both directions via wired or wireless short-range communication means. As the information terminal 8, a tablet terminal or a smartphone equipped with an out-camera 12 and an in-camera 14 and capable of operating by installing an application can be used. Note that the management server 15 can communicate with a plurality of information terminals 8 and a plurality of management personal computers 16, and naturally, it can also communicate with the information terminals 8 and the management personal computers 16 arranged at different golf courses.

[0017] Figure 3 shows the electrical configuration of the information terminal 8. In the figure, in addition to the display unit 9, the operation unit 10, the out-camera 12, and the in-camera 14 described above, the information terminal 8 includes a control means 17, an inertial measurement unit 18, a GPS (Global Positioning System) reception unit 19, a transmission / reception unit 20, and a storage unit 21.

[0018] The control means 17 is configured to include a CPU (Central Processing Unit) and controls the entire information terminal 8 based on the program 22 stored in the storage unit 21. By the CPU executing arithmetic processing according to the program 22, each function of the information terminal 8 is realized.

[0019] The inertial measurement unit 18 incorporates an acceleration sensor 23 and a gyro sensor 24, both of which are inertial sensors, as detection means for detecting the movement of the golf cart 1 to which the information terminal 8 is attached. The acceleration sensor 23 can measure acceleration in the orthogonal three-axis direction, and the gyro sensor 24 can measure angular velocity around each of the three orthogonal axes. The inertial measurement unit 18 measures the acceleration and direction changes of the golf cart 1. The acceleration information and angular velocity information measured by the inertial measurement unit 18 are sent to the determination unit 25 of the control means 17. Alternatively, the golf cart 1 may be equipped with a wheel detection sensor (not shown) that detects the presence or absence and rotation speed of the wheels 3, and the determination unit 25 may determine whether the golf cart 1 is moving by acquiring the detection results from this wheel detection sensor.

[0020] The control means 17 includes a camera control unit 26 that drives and controls the rear camera 12 and the front camera 14. The rear camera 12 and the front camera 14 start driving and taking pictures when they receive a drive signal from the camera control unit 26, and stop driving and taking pictures when they receive a stop signal from the camera control unit 26.

[0021] The GPS receiver 19 constitutes a position measurement means for acquiring the current location of the information terminal 8. By wirelessly receiving radio waves from multiple artificial satellites 27, it measures the three-dimensional position (longitude, latitude, and altitude) of the information terminal 8 and transmits this position information to the control means 17. Note that any position detection device other than the GPS receiver 19 that can detect the current location of the information terminal 8 may be used.

[0022] The transmitting / receiving unit 20 enables bidirectional communication with the management server 15 and the management PC 16 via wired or wireless communication means. As a result, the information terminal 8 can send and receive image data and other information, including various types of information described later, with the management server 15 and the management PC 16.

[0023] The memory unit 21 is composed of various storage devices such as magnetic hard disk drives and semiconductor memory devices, and is capable of writing and reading not only the location information of the information terminal 8 received by the GPS receiver unit 19, but also image data captured by the rear camera 12 and the front camera 14.

[0024] The display unit 9 is composed of a liquid crystal module or liquid crystal panel exposed on the front of the main body of the information terminal 8. As is well known, these liquid crystal modules and liquid crystal panels display information using a dot matrix, in which a large number of subpixels are arranged in a grid.

[0025] The operation unit 10 receives operations from the user and sends electrical operation signals to the control means 17. In the information terminal 8 of this embodiment, the display unit 9 is a touch panel, and the surface of the display unit 9 functions as the operation unit 10.

[0026] The information terminal 8 can display advertisements and other information on its display unit 9, and allows score input by operating the control unit 10. The information terminal 8 can be powered by the golf cart 1.

[0027] Figures 3 and 4 show embodiments in which the information terminal 8 is attached to the roof 6 of the golf cart 1 by an angle adjustment device 28. In the information terminal 8 shown in Figure 4, the front camera 14 is located at the top of the information terminal 8, while in the information terminal 8 shown in Figure 5, the front camera 14 is located in the middle of the information terminal 8. As indicated by the white arrows in Figures 3 and 4, the angle adjustment device 28 can be adjusted in both the vertical and horizontal directions, allowing the information terminal 8 to be fixed at a desired angle. Figures 3 and 4 show the information terminal 8 attached to the angle adjustment device 28 with the rear camera 12 facing downwards. The orientation in which the information terminal 8 is attached is determined by considering the positions of the rear camera 12 and front camera 14, and the range that the rear camera 12 and front camera 14 can capture.

[0028] The determination unit 25 determines whether the rear camera 12 and front camera 14 are capturing the appropriate range based on the detection signal from the gyro sensor 24 and the image data from the rear camera 12 and front camera 14. If the determination unit 25 determines that the appropriate range is not being captured, a warning message M is displayed (notified) on the display unit 9, as shown in Figure 6. Also, at the bottom of the display unit 9, a close button B1 with the words "× Close" and a transition button B2 with the words "Go to Tablet Angle Adjustment" are displayed. When the transition button B2 is tapped, the images from the rear camera 12 (front camera) and the front camera 14 (rear camera) are displayed simultaneously on the display unit 9, as shown in Figure 7, and the angle of the information terminal 8 can be adjusted while viewing these images. At the bottom of the display unit 9, button B1 and a confirmation button B3 with the words "Confirm this angle" are displayed. Once the angle of the information terminal 8 is determined, tap the confirmation button B3. In the case of an information terminal 8 that can use a wide-angle lens as an out-camera 12 or in-camera 14, the angle of the information terminal 8 may be determined and the photo taken while using the wide-angle lens.

[0029] Furthermore, if the information terminal 8 is directly attached and secured to the golf cart 1, and the rear camera 12 and rear camera 14 can capture an appropriate range, then the angle adjustment device 28 does not need to be used, as shown in Figure 1.

[0030] Next, we will explain the operation of the golf cart 1 and how the camera control unit 26 controls the rear camera 12 and the rear camera 14.

[0031] When the inertial measurement unit 18 detects the movement of the golf cart 1, acceleration information and angular velocity information are sent to the determination unit 25. The GPS receiver 19 also sends position information to the determination unit 25. If the determination unit 25 determines that the golf cart 1 is moving forward based on the acceleration information, angular velocity information, position information, and the detection results from the wheel detection sensors, the camera control unit 26 sends a drive signal to the rear camera 12. If the determination unit 25 determines that the golf cart 1 has stopped moving, the camera control unit 26 sends a stop signal to the rear camera 12. While the rear camera 12 is in motion, it continuously captures still images at predetermined time intervals T (e.g., 0.5 seconds or 1.0 second). The captured images are stored as image data in the storage unit 21. This allows the system to capture and store images of the area in front of the golf cart 1 while it is moving forward.

[0032] On the other hand, when the determination unit 25 determines that the golf cart 1 is moving backward based on acceleration information, angular velocity information, position information, and detection results from the wheel detection sensor, the camera control unit 26 sends a drive signal to the in-camera 14. Also, when the determination unit 25 determines that the golf cart 1 has stopped from moving backward, the camera control unit sends a stop signal to the in-camera 14. While in operation, the in-camera 14 continuously captures still images at predetermined time intervals T2 (for example, 0.5 seconds or 1.0 second). The captured images are stored as image data in the storage unit 21. This makes it possible to record the inside and rear of the golf cart 1 when it is moving backward.

[0033] Furthermore, when the determination unit 25 determines that the golf cart 1 is stopped based on acceleration information, angular velocity information, position information, and detection results from the wheel detection sensor, the camera control unit 26 sends a drive signal to the rear camera 12 and the front camera 14. While in operation, the rear camera 12 and the front camera 14 alternately take still images with the rear camera 12 and the front camera 14 at predetermined time intervals T3 (for example, 0.5 seconds or 1.0 second). This allows for capturing and storing images of the front, interior, and rear of the golf cart 1 when it is stopped. In typical tablet devices, it is not possible to activate the rear camera and the front camera simultaneously to take pictures. Therefore, in this embodiment, a method is adopted in which the rear camera 12 and the front camera 14 are alternated at short intervals (for example, 0.5 seconds or 1.0 second), thereby shortening the time interval between the rear camera 12 (for example, 1.0 second or 2.0 seconds) and the time interval between the front camera 14 (for example, 1.0 second or 2.0 seconds) as much as possible, while achieving the capture of images of the front, interior, and rear of the golf cart 1 at approximately the same time.

[0034] Furthermore, if the determination unit 25 determines that the golf cart 1 is moving forward, the camera control unit 26 may send a drive signal to the rear camera 12 and the rear camera 14, and control them to alternately capture still images with the rear camera 12 and the rear camera 14 at predetermined time intervals T3 (for example, 0.5 seconds or 1.0 second). This allows for capturing and storing images of the area in front of the golf cart 1 when it is moving forward, as well as capturing and storing images of the inside and rear of the golf cart 1. Therefore, it is possible to capture and store images of how the driver operates the steering device 5, etc.

[0035] Furthermore, if the determination unit 25 determines that the golf cart 1 is moving in reverse, the camera control unit 26 may send a drive signal to the rear camera 12 and the rear camera 14, and control them to alternately capture still images with the rear camera 12 and the rear camera 14 at predetermined time intervals T3 (for example, 0.5 seconds or 1.0 second). This allows for capturing and storing images of the area in front of the golf cart 1 when it is moving in reverse, as well as capturing and storing images of the inside and rear of the golf cart 1. Therefore, it is possible to capture and store images of how the driver operates the steering device 5, etc. Note that the time intervals T1, T2, and T3 may be the same, or they may be partially or entirely different.

[0036] Since the information terminal 8 receives location information via the GPS receiver 19, the camera control unit 26 may control the golf cart 1 to which the information terminal 8 is attached to by sending a drive signal to the rear camera 12 and the rear camera 14 when the cart is at a predetermined location on the golf course, and taking still images with the rear camera 12 and the rear camera 14. If the cart is at any other location, the camera control unit 26 may send a stop signal to the rear camera 12 and the rear camera 14.

[0037] The golf cart monitoring system according to the present invention operates by launching an application downloaded and installed from the management server 15 to the information terminal 8. Therefore, the control of the rear camera 12 and rear camera 14 by the camera control unit 26 begins when the application is launched, and when the application is stopped, the control of the rear camera 12 and rear camera 14 by the camera control unit 26 also stops. The application may be set to be launched by tapping an icon (not shown) displayed on the display unit 9 of the information terminal 8. Alternatively, the application may be set to launch when the power of the information terminal 8 is turned on.

[0038] Images captured by the rear camera 12 and the front camera 14 are stored as image data in the storage unit 21 along with the date and time information of the time of capture. The information terminal 8 also has an editing unit 29 for editing image data, and can edit the image data captured by the rear camera 12 and the front camera 14 into a stop-motion video. This stop-motion video displays, for example, multiple images that were continuously captured by the rear camera 12 and the front camera 14 from the start to the stop of capture in chronological order. If the rear camera 12 and the front camera 14 take pictures alternately, only the images captured by the rear camera 12 will be made into a stop-motion video, and only the images captured by the front camera 14 will be made into a stop-motion video. These stop-motion videos are stored as recorded data in the storage unit 21.

[0039] In this embodiment, there are two recording modes for storing data in the storage unit 21: a full recording mode and an automatic deletion mode. The full recording mode is set to store all captured recording data in the storage unit 21. On the other hand, the automatic deletion mode is set to sequentially delete recording data taken when the golf cart 1 is stopped, after 10 seconds (a time other than 10 seconds may be set) have elapsed since the recording was made. However, even if the golf cart 1 is stopped, recording data taken between 5 seconds before (a time other than 5 seconds may be set) when the golf cart 1 starts moving and when it starts moving, and between 5 seconds (a time other than 5 seconds may be set) when the golf cart 1 stops while moving, will not be deleted. Furthermore, if the acceleration sensor 23 detects an impact or the like to the golf cart 1, the recording data will not be deleted, and at least 10 seconds (a time other than 10 seconds may be set) of recording data before and after the impact or the like was detected will be stored. Switching between full recording mode and automatic deletion mode is possible by operating the control unit 10, for example, by a golf course manager.

[0040] Recorded data stored in the memory unit 21 can be displayed on the display unit 9. Furthermore, recorded data stored in the memory unit 21 can be transmitted to the management server 15 and the management PC 16 via the transmission / reception unit 20, and can be displayed on the management PC 16's display means 30. Therefore, images and videos captured by the rear camera 12 and the front camera 14 and stored in the memory unit 21 can be viewed on the information terminal 8 and the management PC 16.

[0041] Figure 8 shows how to play back recorded data and how to save it to the management server 15 (cloud). First, tapping the recording data confirmation button B4, which displays the words "Check Recorded Data" from the menu screen, displays a list of recorded data stored in the information terminal 8, organized by date. At this time, recorded data taken with the rear camera 12 (front camera) and recorded data taken with the front camera 14 (rear camera) are displayed separately in different columns. Tapping the date you want to play back displays a list of recorded data taken on that date. At this time, the recorded data is displayed by the time it was taken. Tapping the recorded data for the time you want to play back will play that recorded data. At the bottom of the playback screen, a save button B5 with the words "Save this video" is displayed. Tapping the save button B5 displays a screen asking whether to save the recorded data to the management server 15 (cloud). Tapping the "Yes" button B6 displays a screen confirming that the recorded data will be saved to the management server 15 (cloud). Tapping the "Confirm" button B7 displays a confirmation button, and the recorded data being played is sent to and saved to the management server 15 (cloud). The recorded data saved on the management server 15 (cloud) can be downloaded from the management PC 16, etc.

[0042] As described above, the self-propelled cart monitoring system of this embodiment is a self-propelled cart monitoring system comprising a golf cart 1 as a self-propelled cart and an information terminal 8 attached to the golf cart 1. The information terminal 8 has an out-camera 12 as a first shooting means capable of shooting in front of the information terminal 8 and an in-camera 14 as a second shooting means capable of shooting behind the information terminal 8. The out-camera 12 and the in-camera 14 take pictures according to the operation of the golf cart 1, so that events occurring inside or around the golf cart 1 when the golf cart 1 is moving forward, backward, or stopped can be photographed.

[0043] Furthermore, in this embodiment of the self-propelled cart monitoring system, the load on the information terminal 8 can be reduced compared to when the outer camera 12 and the inner camera 14 are driven simultaneously, because the outer camera 12 and the inner camera 14 do not take pictures at the same time.

[0044] Furthermore, the monitoring system for the self-propelled cart in this embodiment can reliably capture events such as collisions on the front side when the golf cart 1 is moving forward and on the rear side when the golf cart 1 is moving backward, by having the rear camera 12 take pictures when the golf cart 1 is moving forward and the rear camera 14 take pictures when the golf cart 1 is moving backward.

[0045] Furthermore, the monitoring system for the self-propelled cart in this embodiment is capable of reliably capturing incidents such as disputes between occupants of the golf cart 1, as the in-camera 14 is capable of filming inside the golf cart 1.

[0046] Furthermore, in this embodiment of the self-propelled cart monitoring system, the information terminal 8 has a storage unit 21 for saving data, and the out camera 12 and in camera 14 capture still images at predetermined time intervals T1, T2, and T3, and multiple still images are saved as a frame-by-frame video in the storage unit 21. This reduces the amount of data stored in the storage unit 21 compared to when a video is captured and saved.

[0047] Furthermore, the monitoring system for the self-propelled cart in this embodiment includes an angle adjuster 28 that can adjust the orientation of the information terminal 8. If the orientation of the information terminal 8 is not appropriate, a warning is issued, allowing the user to check the content of the warning and adjust the orientation of the information terminal 8 using the angle adjuster 28.

[0048] Furthermore, the program of this embodiment includes an information terminal 8 attached to the golf cart 1, which has an out-camera 12 capable of taking pictures in front of the information terminal 8 and an in-camera 14 capable of taking pictures behind the information terminal 8. By having the computer in the information terminal 8 control the out-camera 12 and the in-camera 14 so that they do not take pictures at the same time, the load on the information terminal 8 can be reduced compared to when the out-camera 12 and the in-camera 14 are driven simultaneously.

[0049] Furthermore, the program of this embodiment includes an information terminal 8 attached to the golf cart 1, which has an out-camera 12 capable of taking pictures in front of the information terminal 8 and an in-camera 14 capable of taking pictures behind the information terminal 8. By causing the computer of the information terminal 8 to execute a step of taking pictures with the out-camera 12 when the golf cart 1 is moving forward and a step of taking pictures with the in-camera 14 when the golf cart 1 is moving backward, it is possible to reliably capture events such as collisions on the front side when the golf cart 1 is moving forward and on the rear side when the golf cart 1 is moving backward.

[0050] It should be noted that the present invention is not limited to the embodiments described above, and various modifications can be made within the scope of the gist of the invention. For example, the self-propelled cart may be an electric wheelchair or a self-propelled cart known as a senior mobility scooter, in addition to a golf cart. [Explanation of symbols]
