Description

[Technical field]

[0001] The present invention relates to an imaging system for vehicles with a large number of passengers, such as buses and trains, etc. In particular, the present invention relates to an imaging system for vehicles that captures images of the interior of a vehicle, counts the number of passengers getting on and off, and monitors the interior of the vehicle. [Background technology]

[0002] 2. Description of the Related Art Conventionally, in vehicles such as buses and trains, where a large number of passengers board and disembark, cameras or the like are installed inside the vehicle to check the passengers getting on and off and to check the situation inside the vehicle.

[0003] For example, Patent Document 1 listed below discloses a bus photography device that uses a door camera installed above the driver's seat to photograph the boarding and alighting entrance and passengers getting on and off, and a seat camera installed above the windshield to photograph passengers sitting in their seats.

[0004] In Patent Document 1, the door and seat cameras are used to film the interior of the bus in order to monitor for the presence or absence of crime. By installing door and seat cameras inside a bus in this way, it is possible to film passengers getting on and off the bus and count the number of passengers, or to constantly film the interior of the bus to monitor the situation inside the bus.

[0005] In recent years, there has been an increase in accidents in which children are left behind on school buses, especially those used to transport children to and from kindergartens and other schools. As a result, it is being considered to install door cameras and seat cameras, as described in Patent Document 1, on these school buses in order to prevent such accidents from occurring. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] JP 2005-303523 A Summary of the Invention [Problem to be solved by the invention]

[0007] Incidentally, when considering installing such vehicle-mounted photography systems on existing buses and the like, reducing the number of cameras as much as possible will reduce installation costs, making it easier to popularize vehicle-mounted photography systems.

[0008] However, the vehicle photography system in the aforementioned Patent Document 1 requires at least two cameras: a door camera and a seat camera, each of which needs to count the number of occupants and photograph and monitor the interior of the bus, which poses the problem of requiring a minimum of two cameras.

[0009] The present invention has been made in consideration of the above-mentioned points, and its object is to provide a vehicle photography system that is capable of counting the number of passengers getting on and off the vehicle and photographing and monitoring the condition inside the vehicle using as few cameras as possible, thereby promoting the spread of vehicle photography systems. [Means for solving the problem]

[0010] In order to achieve this object, the present invention provides an imaging system for a vehicle in which a large number of passengers get on and off, in which a camera body is installed at a position inside the vehicle where it can image the boarding and alighting area of ​​the vehicle and the seats in which the passengers sit with the same angle of view, and is characterized in that the camera body is used in a counting mode for counting the number of passengers when the vehicle is in operation, and in an interior monitoring mode for photographing and monitoring the interior of the vehicle when the vehicle is not in operation.

[0011] Specifically, the first invention is characterized in that it comprises a first camera body installed at a position inside the vehicle where it can photograph the boarding and alighting area of ​​the vehicle where passengers board and alight and the seats where the passengers sit with the same angle of view, and a control means for controlling the first camera body to be used in a counting mode for counting the number of passengers when the vehicle is in operation, and in an interior monitoring mode for photographing and monitoring the interior of the vehicle when the vehicle is not in operation.

[0012] According to this configuration, the control means uses the first camera body in a count mode for counting the number of occupants when the vehicle is in operation, and in an interior monitoring mode for photographing and monitoring the interior of the vehicle when the vehicle is not in operation.

[0013] Therefore, a counting function for counting the number of passengers getting on and off the vehicle and an interior monitoring function for photographing and monitoring the interior of the vehicle can be performed by one of the first camera bodies.

[0014] The second invention is characterized in that it comprises a second camera body installed in a position inside the vehicle where it can photograph the seat in which the occupant is seated, and the first camera body is installed at the upper part of a side surface on one left-right side of the vehicle interior, or at a side end part on one left-right side of the ceiling, and the second camera body is installed at the upper part of a side surface on the other left-right side of the vehicle interior, or at a side end part on the other left-right side of the ceiling, in a position diagonally opposite the first camera body and offset in the fore-and-aft direction of the vehicle.

[0015] According to this configuration, the angle of view captured by the first camera body and the angle of view captured by the second camera body can be used to capture images of the interior of the vehicle while minimizing blind spots caused by seat backs, etc.

[0016] In other words, since the first camera body and the second camera body are positioned diagonally opposite each other on both the left and right sides of the vehicle, blind spots caused by the seat backs are eliminated and the entire interior of the vehicle can be photographed, even in a long interior space with multiple seats lined up in the fore-and-aft direction of the vehicle.

[0017] Therefore, with only two camera bodies, the first camera body and the second camera body, it is possible to capture and monitor the entire interior of a vehicle that is long in the front-to-rear direction of the vehicle without any blind spots.

[0018] Therefore, the entire interior of a vehicle that is long in the fore-and-aft direction can be photographed without any blind spots using a small number of camera bodies, so that the number of camera bodies can be reduced while maintaining the monitoring performance when using the camera bodies in the in-vehicle monitoring mode.

[0019] The third invention is characterized in that it comprises a monitor that displays a first image captured by the first camera body and a second image captured by the second camera body on the same screen, and a control means that displays either the first image or the second image displayed on the monitor in a left-right inverted manner.

[0020] According to this configuration, the first image captured by the first camera body and the second image captured by the second camera body are images with the front-to-back orientation of the interior of the vehicle reversed because the first camera body and the second camera body are installed in different positions on the left and right sides of the vehicle. However, by flipping one of the images left to right and displaying it on the monitor, the front-to-back orientation of the vehicle is displayed as an image with the same orientation.

[0021] Therefore, the driver of the vehicle or the like viewing the monitor screen can check the first image and the second image without feeling any discomfort.

[0022] In other words, the driver etc. checks the status of passengers getting in and out of the vehicle on the monitor screen, but if the front-to-back orientation of the first image and the second image are reversed, it will be difficult to tell at a glance whether the passengers are getting in or out. However, by flipping one of the images left to right, the driver etc. will not feel this sense of discomfort.

[0023] This eliminates the sense of incongruity on the monitor screen that occurs when the first camera body and the second camera body are installed in different positions on the left and right sides of the vehicle, enabling the driver, etc. to accurately check the status of the occupants, etc.

[0024] The fourth invention is characterized in that the installation position of the first camera body is set at the upper part of the side surface on the side where the boarding / alighting door of the boarding / alighting section is provided, or at the side end of the ceiling.

[0025] According to this configuration, the first camera body is installed at the upper part of the side surface on the side where the boarding / alighting door is provided, or at the side end of the ceiling.

[0026] This allows the first camera body to capture an image of the head of an occupant getting on and off the boarding / alighting section, thereby enabling detection of the occupant.

[0027] Therefore, when the first camera body photographs the occupants and counts the number of occupants, the occupants do not overlap each other, so that the number of occupants can be counted accurately.

[0028] Therefore, the count mode of the first camera body for counting the number of occupants can be made to function with greater accuracy. Effect of the Invention

[0029] As described above, according to the present invention, the counting function of counting the number of passengers getting in and out of the vehicle and the interior monitoring function of photographing and monitoring the condition inside the vehicle can be performed by one of the first camera bodies.

[0030] Therefore, by using as few cameras as possible to count the number of passengers getting on and off in a vehicle with a large number of passengers and to photograph and monitor the condition inside the vehicle, the vehicle photography system can be promoted in widespread use.

[0032] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. The following description of the preferred embodiments is merely illustrative in nature and is not intended to limit the present invention, its application, or its uses.

[0033] (Embodiment 1) FIG. 1 is a plan view of the interior of a vehicle in which the vehicle photography system of this embodiment 1 is installed, specifically, an overall plan view of the interior of a school bus, FIG. 2 is an oblique view showing the installation state of the first camera inside the vehicle, FIG. 3 is an oblique view showing the installation state of the second camera inside the vehicle, and FIG. 4 is an oblique view showing the installation state of the confirmation button of embodiment 1 inside the vehicle.

[0034] The vehicle-mounted photography system of the present embodiment 1 is installed on a school bus B that kindergarten children use when commuting to and from school.

[0035] The school bus B is a so-called microbus, and the interior BR has multiple seats Sa-Se arranged in a row in the fore-aft direction of the vehicle. Specifically, the driver's seat Sa is installed in the front right part, and two-seater seats Sb... are arranged in a row in the fore-aft direction behind it. In addition, one-seater seats Sc... are arranged in a row in the fore-aft direction of the vehicle on the left side, separated by an aisle Ba that extends in the fore-aft direction in the center.

[0036] A boarding and alighting section C equipped with an entrance Ca and a boarding and alighting door Cb for passengers to board and alight is provided at the front center of the left side of the school bus B. A flip-up auxiliary seat Sd is provided behind the boarding and alighting section C, and a flip-up auxiliary seat Se is also provided at the rear end on the right side.

[0037] The vehicle imaging system of the present embodiment 1 is installed in the interior BR of this school bus B. First, an interior monitor 1 is installed in front of the driver's seat Sa, and a control box 2 and the like are installed behind the driver's seat Sa. Also, a socket power cord 3 that is inserted into a cigarette lighter socket of a power source is installed near the driver's seat Sa.

[0038] A first camera 4 is installed above the auxiliary seat Sd behind the boarding and disembarking area C. A second camera 5 is installed above the seat Sb at the rear of the vehicle on the right side. This second camera 5 is installed in a position that is offset in the fore-and-aft direction of the vehicle from the first camera 4, that is, diagonally opposite. Furthermore, a confirmation button 6 is installed above the rearmost auxiliary seat Se in the vehicle.

[0039] Specifically, the above-mentioned first camera 4 is fixed to the upper part of the window glass BW1 provided on the left side of the school bus B via a fixing member 41, as shown in Fig. 2. Therefore, it can be installed without processing the roof trim BT, which serves as the ceiling, etc.

[0040] The first camera 4 is a so-called semi-spherical camera having a 360° angle of view. Ca denotes a boarding / alighting entrance, and Cb denotes a boarding / alighting door.

[0041] As shown in Fig. 3, the second camera 5 is also fixed to the upper part of the windshield BW2 on the right side of the school bus B via a fixing member 51. Therefore, the second camera 5 can also be installed without processing the roof trim BT or the like. The second camera 5 is also a semi-spherical camera with a 360° angle of view. BP denotes a vehicle body pillar extending in the vertical direction.

[0042] As shown in Fig. 4, the confirmation button 6 is fixed to the top of the body frame BF, which extends in the vertical direction and is provided at the rear end of the school bus B, via double-sided tape (not shown) or the like. By fixing the confirmation button 6 to the sturdy body frame BF in this way, the driver or the like can reliably press the confirmation button 6 with force. The confirmation button 6 has two buttons, an upper one and an lower one, the upper one being a shutter button 6a that takes a still image, and the lower one being a completion button 6b that stops an alert, which will be described later.

[0043] Next, the system structure of the vehicle photography system of this embodiment 1 and the control method of the system will be described. Fig. 5 is a system structure diagram, Fig. 6 is a main flowchart when going to the kindergarten, Fig. 7 is a main flowchart when going to the kindergarten, Fig. 8 is a flowchart for the boarding and alighting counting mode, and Fig. 12 is a flowchart for the bus monitoring mode. The other figures will be explained when explaining each flowchart.

[0044] 5, the vehicle imaging system M of the present embodiment 1 is provided with a male portion 3a of a socket power cord 3 that is inserted into a cigarette lighter socket BZ to receive power supply, and an in-vehicle monitor 1 connected to a control box 2, near the driver's seat. Note that the power cord 3 may be directly connected to an in-vehicle power source (not shown) to receive power supply without using the cigarette lighter socket BZ.

[0045] Also, behind the driver's seat, there is a standby power supply 7 having a three-port female portion 3b of the socket power cord 3 and a male portion 7a that is inserted into the female portion 3b of the socket power cord 3, a switch 8 having a male portion 8a that is inserted into the female portion 3a of the socket power cord 3 and connected to the standby power supply 7 to switch the power source, a control box 2 connected to this switch 8 to receive power, a USB hub 9 connected to this control box 2, and an LTE dongle 10 (LTE communication device) connected to the USB hub 9.

[0046] The standby power supply 7 is configured to receive power from the cigarette lighter socket BZ and store electricity when the engine is on, and to supply electricity to the control box 2 etc. via the switch 8 when the engine is off.

[0047] A Bluetooth module 2a is provided within the control box 2, and the confirmation button 6 and the control box 2 are configured to communicate wirelessly via a Bluetooth line.

[0048] Furthermore, the control box 2 is configured to wirelessly communicate with a staff room monitor 11 installed in the staff room via an LTE line using the aforementioned LTE dongle 10.

[0049] Although not shown in detail, the female portion 3b of the socket power cord 3 is connected to a drive recorder device or the like.

[0050] The control box 2 is also connected to the first camera 4 and the second camera 5 installed in the vehicle interior BR, and images captured by the first camera 4 and the second camera 5 are input to the control box 2. A control unit such as a CPU (not shown) installed inside the control box 2 performs predetermined image processing on the captured images, and displays them on the vehicle interior monitor 1, the staff room monitor 11, etc.

[0051] If the school bus B is long and has more seats inside, a third camera 13 drawn by an imaginary line may be connected. This third camera 13 is preferably installed on the left side of the school bus B as the first camera 4, and diagonally opposite the second camera 5, offset in the fore-and-aft direction of the vehicle.

[0052] When children arrive at the kindergarten, the vehicle-mounted photography system M configured in this way is controlled (used) according to the main flow for when the children arrive at the kindergarten, as shown in Fig. 6. Note that the flow shown below is a flow for easily explaining the usage state of the vehicle-mounted photography system M, and is not an electrical control flow of the control box alone.

[0053] First, the system is started by an engine ON signal at S1. When the engine starts, electricity flows from the cigarette lighter socket BZ and the vehicle control system M is started. As a result, the first camera 4, the second camera 5, etc. take pictures of the situation inside the vehicle BR, and the taken images are transmitted to the control box 2.

[0054] Both the first camera 4 and the second camera 5 are semi-spherical cameras with a 360° angle of view, so the images captured by these cameras include the boarding and disembarking area C and seats Sa to Se of the vehicle interior BR.

[0055] After that, a bus operation is performed at S2. This bus operation means that the school bus B moves to a specified destination, and the bus operation here means that the school bus B leaves the garage and heads toward the first bus stop.

[0056] Next, in S3, it is judged whether the bus has arrived at the bus stop. This bus stop refers to the bus stop where the children board school bus B. If it is judged in S3 that the bus has not arrived at the bus stop (NO judgment), the bus returns to S2 again and continues operating.

[0057] On the other hand, if it is determined in S3 that the bus has arrived at the bus stop (YES), the bus transitions to a boarding / alighting counting mode in S4. This boarding / alighting counting mode is a mode for counting the number of children boarding and alighting. Details of this boarding / alighting counting mode will be described later. In this boarding / alighting counting mode in S4, the number of children boarding at the bus stop is counted.

[0058] After that, in S5, it is determined whether service has resumed. If it is determined in S5 that service has not resumed (determination is NO), the system returns to boarding / alighting count mode in S4 and counts the number of children getting on and off. On the other hand, if it is determined in S5 that service has resumed (determination is YES), the system moves to bus operation in S6. This bus operation in S6 also means that school bus B is moving to a specified destination, but bus operation here means that school bus B is heading to the next stop or the kindergarten.

[0059] Then, in S7, it is determined whether the bus has arrived at the kindergarten. If it is determined in S7 that the bus has not arrived at the kindergarten (NO determination), the bus returns to S2 again and continues operating. Then, the bus moves to the next bus stop. In this way, the bus stops at multiple bus stops until it arrives at the kindergarten, and multiple children board the bus.

[0060] On the other hand, if it is determined in S7 that the bus has arrived at the kindergarten (YES), the bus transitions to a boarding / alighting count mode in S8. This boarding / alighting count mode, like the boarding / alighting count mode in S4, is a mode for counting the number of children getting on and off the bus. In this boarding / alighting count mode in S8, the bus counts the number of children getting off the bus when it arrives at the kindergarten.

[0061] After that, in S9, it is judged whether disembarking is complete, and if it is judged not to be complete (NO judgement), the process goes back to S8, where the boarding and alighting count mode is started, and the number of children getting on and off is counted again. On the other hand, if it is judged to be complete in S9 (YES judgement), the process goes to S10.

[0062] In S10, the bus moves to the parking lot. School bus B moves to the parking lot and stops there. After that, in S11, the bus switches to an interior check mode with an engine OFF signal. In S11, the bus switches to a mode in which the interior of the bus is checked, provided that the engine is stopped. This interior check mode is a mode in which the driver or nursery school teacher checks the condition inside the bus when parking school bus B in the parking lot.

[0063] After the engine is stopped, power supply from the cigarette lighter socket BZ is cut off, so electricity is automatically supplied from the standby power source 7 by the switch 8. This supply of electricity from the standby power source 7 continues as long as the standby power source 7 has power.

[0064] Next, an alert is issued in S12. This alert is an alert sound being emitted in the vehicle or an alert being displayed on the in-vehicle monitor 1. After that, in S13, it is determined whether the confirmation button has been pressed.

[0065] As mentioned above, the confirmation button 6 is installed on the body frame BF at the rear end of the interior of the vehicle, so that the driver or nursery teacher, etc. must move to the rear of the interior BR in order to press the confirmation button 6 (complete button 6b).This allows the driver or nursery teacher, etc. to find a sleeping child in the interior BR, preventing the occurrence of an accident in which the child is left behind.

[0066] If it is not determined in S13 that the confirmation button has been pressed (determination of NO), the process returns to S12 and the alert notification continues. On the other hand, if it is determined that the confirmation button has been pressed (determination of YES), the process proceeds to S14, where the alert is stopped. When the confirmation button 6 is pressed in this manner, the warning sound and warning display are stopped.

[0067] Thereafter, the system transitions to an in-bus monitoring mode at S15. This in-bus monitoring mode is a mode in which the interior BR of the parked school bus B is photographed and monitored by the first camera 4 and the second camera 5. By using this in-bus monitoring mode, even if a child is left behind inside the interior BR, the child can be found.

[0068] In other words, while the in-bus confirmation mode prevents drivers (humans) from leaving children behind, the in-bus monitoring mode is also set to reliably prevent children from being left behind. Details of the in-bus monitoring mode will be described later.

[0069] Then, in S16, it is determined whether the standby power supply has power, and if it is determined that there is power (YES determination), the process transitions again to the bus monitoring mode in S15, and if it is determined that there is no power (NO determination), the control ends. In other words, the bus monitoring mode is configured to be performed as long as there is power in the standby power supply 7.

[0070] On the other hand, when the children leave the nursery school, the photography system M of the vehicle is controlled (used) according to the main flow for leaving the nursery school shown in FIG.

[0071] First, in S21, the system is started by an engine ON signal. When the engine starts, electricity flows from the cigarette lighter socket BZ and the vehicle control system M is started. This causes the first camera 4, the second camera 5, etc. to capture images of the interior of the vehicle BR and transmit the captured images to the control box 2.

[0072] After that, bus service is performed at S22. Bus service here means the situation where the school bus leaves the garage and heads to the kindergarten.

[0073] Next, in S23, it is determined whether the child has arrived at the kindergarten. At the kindergarten, the child who is to be dropped off boards the school bus. If it is determined in S23 that the child has not arrived at the kindergarten (NO determination), the process returns to S22 again and the bus continues to operate.

[0074] On the other hand, if it is determined in S23 that the child has arrived at the kindergarten (YES), the process proceeds to a boarding / alighting counting mode in S24. In this boarding / alighting counting mode, the number of children boarding the school bus at the kindergarten is counted. This boarding / alighting counting mode is similar to the boarding / alighting counting modes in S4 and S8.

[0075] Then, in S25, it is judged whether or not the service has been resumed. If it is judged not to be resumed in S25 (NO judgment), the system returns to the boarding and alighting count mode in S24 and counts the number of children boarding again.

[0076] On the other hand, if it is determined in S25 that operation should be resumed (YES), the system moves to bus operation in S26. Bus operation here means that the school bus leaves the kindergarten and heads toward the first drop-off point. This drop-off point is where the children get off the school bus.

[0077] Thereafter, in S27, it is determined whether the bus has arrived at the drop-off point. If it is determined in S27 that the bus has not arrived at the drop-off point (NO determination), the process returns to S26 and the bus continues to operate.

[0078] On the other hand, if it is determined in S27 that the bus has arrived at the drop-off point (YES), the bus transitions to a boarding / alighting counting mode in S28. In this boarding / alighting counting mode in S28, the number of children who get off the bus at the drop-off point is counted. This boarding / alighting counting mode is similar to the boarding / alighting counting modes in S4 and S8, and will be described in detail later.

[0079] Thereafter, in S29, it is determined whether or not operation has resumed, and if it is determined not to have resumed operation (determination of NO), the process again shifts to the boarding / alighting number counting mode in S28, and the number of children who disembark is counted again. On the other hand, if it is determined to have resumed operation in S29 (determination of YES), the process shifts to S30.

[0080] In S30, it is judged whether the child has arrived at the kindergarten. If it is judged that the child has not arrived at the kindergarten (NO judgment), the process moves to S26 and the bus continues to operate. Then, in S27 and after, it is checked whether the child has arrived at the next drop-off point.

[0081] In this way, even when children are being dropped off, the school bus moves to multiple drop-off points before returning to the kindergarten, and multiple children are dropped off at each drop-off point.The number of children getting off the school bus at each drop-off point is then counted.

[0082] If it is determined in S30 that the bus has arrived at the kindergarten (YES), the bus moves to the parking lot in S31. In S31, the bus moves to the parking lot and stops there. After that, in S32, the bus transitions to the interior check mode with an engine OFF signal. In S32, as in S11, the bus transitions to the interior check mode on the condition that the engine is stopped.

[0083] Next, an alert is issued in S33. As in S12, this alert is issued by sounding an alarm in the vehicle or displaying an alarm on the vehicle monitor. After that, in S34, it is determined whether the confirmation button has been pressed.

[0084] With S34, even when dropping off a child, the driver or other person in charge needs to go to the rear of the vehicle and press the confirmation button after the trip has finished. Therefore, if a child is still asleep inside the vehicle, the driver or other person in charge can find the child and prevent an accident in which the child is left behind.

[0085] If it is not determined in S34 that the confirmation button has been pressed (determination of NO), the process returns to S23 and the alert notification continues. On the other hand, if it is determined that the confirmation button has been pressed (determination of YES), the process proceeds to S35, where the alert is stopped. Thus, when the confirmation button is pressed, the warning sound and warning display are stopped.

[0086] Thereafter, the process shifts to the bus monitoring mode in S36, which is similar to the bus monitoring mode in S15.

[0087] This in-bus monitoring mode makes it possible to find children using the first camera, etc., even if they have been left behind inside the bus after the bus has finished transporting children to drop off at the school.

[0088] In other words, even after the bus has finished its journey to unload the children, the in-bus inspection mode prevents the driver (a human) from leaving any children behind, and the in-bus monitoring mode is also set to further ensure that no children are left behind.

[0089] Then, in S37, it is determined whether there is power in the backup power source, and if it is determined that there is power (YES determination), the process transitions back to the bus monitoring mode in S36, and if it is determined that there is no power (NO determination), the control ends. In other words, even after the bus service has ended when the children leave the school, the bus monitoring mode continues as long as there is power in the backup power source.

[0090] Next, the boarding and alighting count mode will be described with reference to Fig. 8. Fig. 9 is a monitor screen displayed on an in-car monitor, Fig. 10 is an explanatory diagram for explaining the boarding count method, and Fig. 11 is an explanatory diagram for explaining the alighting count method.

[0091] First, in S41, the interior of the vehicle is photographed by the first camera 4. Then, in S42, a person is detected in the image recognition enhanced area in the photographed image.

[0092] The image recognition strengthening area is the area below the recognition distinction line L1 shown in the image on the monitor screen in Fig. 9. The image of the area above the recognition distinction line L1 is an image of the scenery outside the vehicle, so if the image of this upper area were also strengthened and captured, the control of the image recognition would be disturbed. For this reason, the image of this area is not captured as much as possible to improve the accuracy of image recognition.

[0093] Here, detecting a person means detecting a person using, for example, a rectangular occupant detection frame Pm shown in the image on the monitor screen in Fig. 9. This occupant detection frame Pm detects a part in the image where a specific movement is occurring as a "person" using, for example, AI (Artificial Intelligence) technology, and displays the part detected as the "person" in a rectangular frame on the monitor screen.

[0094] Next, in S43, it is determined whether the person (Pm) has crossed the passage determination line Lg from bottom to top. In this case, a line slanting diagonally upward to the right in the image (first image G4) on the right side of the monitor screen in Fig. 9 is defined as the passage determination line Lg, and it is determined whether the occupant detection frame Pm as a person has crossed this passage determination line Lg from bottom to top.

[0095] In other words, as shown in Figure 10, if the lower side of the passing judgment line Lg is defined as outside the vehicle and the upper side as inside the vehicle, when the occupant detection frame Pm passes from the lower side to the upper side, it can be inferred that a person has entered the vehicle, and therefore, when this situation is detected, it is determined that a person has entered the vehicle.

[0096] The passing determination line Lg is provided only in the image (first image G4) captured by the first camera 4, and the number of passengers getting on and off is counted by the first camera 4. In the first embodiment, the passing determination line Lg is a line connecting the inner end of the boarding / alighting door Cb of the boarding / alighting section C that is opened and folded into the vehicle and the inner end of the handrail Cc (see FIG. 9).

[0097] If it is determined in S43 that the person (Pm) has crossed the passing judgment line Lg from bottom to top (YES determination), the number of passengers is counted as "+1" in S44. In other words, the number of passengers is counted as increasing by one.

[0098] On the other hand, if it is determined that the person (Pm) has not crossed the passage determination line Lg from bottom to top (NO determination), the process proceeds directly to S45.

[0099] In S45, it is determined whether or not a person (Pm) has crossed the passage determination line Lg from above downward. This is to determine whether or not the occupant detection frame Pm as a person has crossed the passage determination line Lg on the monitor screen in FIG.

[0100] That is, as shown in Figure 11, in this case too, if the lower side of the passing judgment line Lg is defined as outside the vehicle and the upper side as inside the vehicle, when the occupant detection frame Pm passes from the upper side to the lower side, it can be inferred that a person has got out of the vehicle, and therefore, when this situation is detected, it is determined that the person has got out of the vehicle.

[0101] If it is determined in S45 that the person (Pm) has crossed the passing judgment line Lg from above downward (YES determination), the number of people getting off is counted as "+1" in S46. In other words, the number of people getting off is counted as increasing by one.

[0102] On the other hand, if it is determined that the person (Pm) has not crossed the passage determination line Lg from above to below (NO determination), the process proceeds directly to S47.

[0103] In S47, the number of people on the bus, the number of people getting on, and the number of people getting off are calculated as "number of people on the bus = number of people getting on - number of people getting off", and displayed on the in-vehicle monitor 1. For example, the monitor screen in Fig. 9 is configured to display a display frame field H for the number of people on the bus, etc., and displays the number of passengers Hb as 20, the number of people getting off Hc as 13, and the number of people on the bus Ha as 7.

[0104] Furthermore, the lower section Hd of the display frame H displays "Boarding / Alighting" to let the driver or the like know that the vehicle is currently being controlled in the boarding / alighting number counting mode.

[0105] Thus, the boarding / alighting counting mode ends, and the process returns to the main flow for arriving at the kindergarten in FIG. 6 or the main flow for leaving the kindergarten in FIG.

[0106] 9, the image at the top left is the second image G5 captured by the second camera 5, and the image at the top right is the first image G4 captured by the first camera 4. The first image G4 is displayed on the monitor screen after being flipped left to right so that the right side of both images is the front side of the vehicle.

[0107] Also, at the bottom of the monitor screen, the above-mentioned display frame H is displayed, which displays the current number of people on the bus Ha, the number of people getting on Hb, the number of people getting off Hc, the current mode, etc. And to the right of that, the LTE communication status He is displayed.

[0108] In this way, by displaying the monitor screen of the in-vehicle monitor 1, the driver and others can recognize the situation inside the vehicle BR, the status of the children on board, and further, how the vehicle's photography system M is being controlled.

[0109] Next, the bus interior monitoring mode will be described with reference to Fig. 12. First, in S51, the interior BR of the bus is photographed by the first camera 4 and the second camera 5. In S52, a person (Pm) is detected in the image recognition enhanced area in the photographed image.

[0110] Here, detecting a person means, as in S42, detecting a person using the occupant detection frame Pm shown in the image on the monitor screen in Fig. 9. As described above, this occupant detection frame Pm is displayed as a square frame in the image (G4, G5) on the in-car monitor 1 by detecting a part in the image where a specific movement is occurring using AI technology or the like as a "person."

[0111] Next, in S53, it is determined whether a person (Pm) is detected. If a person (Pm) is not detected (NO determination), the process proceeds directly to RETURN. Then, this flow of the in-bus monitoring mode is repeated many times.

[0112] On the other hand, if a person (Pm) is detected in S53 (YES judgment), an alert notification is issued in S54. This alert notification, like S12 and S33, also involves a warning sound being sounded in the vehicle and a warning being displayed on the in-vehicle monitor 1.

[0113] Then, in S55, a warning is also displayed on the staff room monitor 11. As a result, even the kindergarten staff room, which is far from school bus B, can recognize that a person has been detected inside school bus B, so that a nursery school teacher can rescue the child, thereby reliably preventing the child from being left behind.

[0114] Thereafter, in S56, it is determined whether the confirmation button 6 has been pressed. If it is determined that the confirmation button 6 has not been pressed, the process returns to S54, and the alert notification continues.

[0115] On the other hand, if it is determined that the confirmation button 6 has been pressed (YES determination), the process proceeds to S57, where the alert is stopped. Thus, when the confirmation button 6 is pressed, the warning sound and warning display are stopped. Also, in S58, the warning display on the staff room monitor 11 is stopped.

[0116] In this way, in this embodiment 1, when the in-bus monitoring mode is executed, if a child is found inside school bus B, a warning message will be displayed on the in-car monitor 1 and the staff room monitor 11, and a warning sound will continue to sound on school bus B, unless the confirmation button 6 installed inside school bus B is pressed, so that kindergarten teachers or adults near the school bus can reliably rescue the child who has been left behind on school bus B.

[0117] The display screen of the in-vehicle monitor 1 in the vehicle imaging system M of the first embodiment will be described below.

[0118] Figure 13 shows the monitor screen in boarding and alighting count mode (when boarding), Figure 14 shows the monitor screen in boarding and alighting count mode (when disembarking), Figure 15 shows the monitor screen immediately after the engine is stopped, Figure 16 shows the monitor screen in interior check mode, Figure 17 shows the monitor screen after operating the check button, Figure 18 shows the monitor screen in bus interior monitoring mode, Figure 19 shows the monitor screen when an abnormality is detected, and Figure 20 shows the monitor screen after checking the interior of the vehicle.

[0119] As shown in Figure 13, when boarding in the boarding / alighting count mode, when a child boards at the boarding platform, the child (Pm) is detected from the first image G4 taken by the first camera 4 (the child's head is detected by the occupant detection frame Pm), and when the child (Pm) crosses the passing determination line Lg from bottom to top, he or she is counted as one person boarding.

[0120] In this embodiment, the first camera 4 is installed above the auxiliary seat Sd behind the boarding and disembarking area C, so people are detected by head movement. This allows children getting into the car to be accurately detected one by one. This prevents children from overlapping and making it difficult to count the number of people accurately.

[0121] In this way, the number of passengers on the bus can be counted accurately, so in the display frame H, the number of people on the bus Ha is displayed as 8, which is 1 more person than the 7 already on board. The number of passengers on the bus Hb is displayed as 8, which is the cumulative number, and the number of passengers disembarking Hc is displayed as 0, since no one has disembarked. The current mode, "Boarding and disembarking," is displayed in the lower column Hd of the display frame.

[0122] As shown in Figure 14, when disembarking in the boarding / alighting count mode, when a child disembarks at a kindergarten, the child (Pm) getting off is detected from the first image G4 captured by the first camera 4 (the child's head is detected by the occupant detection frame Pm), and when the child (Pm) crosses the passing determination line Lg from top to bottom, he or she is counted as one person getting off.

[0123] By counting the number of passengers getting off in this way, in the display frame H, the number of passengers getting off Hc is shown as a cumulative value of 5, the number of passengers boarding Hb is shown as a cumulative value of 12, and the number of passengers on the bus Ha is shown as 7.

[0124] As shown in Fig. 15, immediately after the engine is stopped, the monitor screen displays the first image G4 and the second image G5, but since there are no children inside the bus, no children (Pm) are detected. However, the display frame section H displays the cumulative results of person detection from when the engine is started to when it is stopped, with the number of people on the bus Ha showing 0, the number of people getting on Hb showing 12, and the number of people getting off Hc showing 12. Also, the lower section Hd of the display frame displays "Waiting."

[0125] 16, when the vehicle interior confirmation mode is entered, there is no change in the first image G4 and the second image G5, but a change occurs in the display frame H. The background of the lower section Hd of the display frame H turns red (hatched with diagonal lines), for example, and a message is displayed saying "Please check inside the bus. After checking, press the confirmation completion button."

[0126] By displaying the monitor screen in this manner, the driver or the like is prompted to operate the confirmation button 6 (the completion button 6b). Furthermore, unless the confirmation button 6 is operated, the vehicle interior confirmation mode will not be released as described above, so the driver can be forced to operate the confirmation button 6.

[0127] As shown in Fig. 17, when the confirmation button 6 is operated, the monitor screen changes. The background of the lower section Hd of the display frame section H returns to the normal state (e.g., blue), and the message "Confirmation completed, moving to in-bus monitoring mode" is displayed.

[0128] By displaying the monitor screen in this way, the driver and others can be made aware that the confirmation button 6 has been operated and the bus has switched to monitoring mode inside the bus. The childcare worker who operated the confirmation button 6 is reflected in the second image G5 on the monitor screen.

[0129] 18, when the bus monitoring mode is entered, a change occurs in the display frame H. The background of the lower section Hd of the display frame H turns green (dot hatching), for example, and the message "Monitoring whether there are any people on the bus" is displayed.

[0130] By displaying the monitor screen in this manner, the driver and others can be made aware that the mode has changed to in-bus monitoring mode.

[0131] When controlled in this in-bus monitoring mode, if human movement is detected in the image captured by the first camera 4 (first image G4) or the image captured by the second camera 5 (second image G5), the monitor screen will change to the one shown in Figure 19 when an abnormality is detected.

[0132] For example, if abnormal movement is detected in a corner of the second image G5, it is determined that a person has been detected, and an occupant detection frame Pm is displayed on the second image G5. In addition, the background of the lower section Hd of the display frame section H also turns red (diagonal hatching), for example, and a message is displayed saying, "Please check inside the bus. After checking, press the confirmation completion button."

[0133] The display on this monitor screen is also transmitted to the staff room monitor 11 via the LTE line and displayed on the staff room monitor 11.

[0134] Therefore, the nursery school teacher in the staff room can check the monitor screen and know that a child has been left behind inside school bus B. This allows the nursery school teacher to rescue the child, preventing the occurrence of an incident in which a child is left behind.

[0135] 19, even if the number of people on the bus Ha in the display frame section H is set to 0, if some mistake occurs, there is a possibility that a child may be left behind inside the vehicle. Even in such a case, the problem of children being left behind can be solved by capturing and monitoring the interior of the school bus B with the first camera 4 and the second camera 5 even after the engine is stopped as in the present embodiment 1.

[0136] After that, when the childcare worker or the like rescues the child from the bus and presses the confirmation button 6 (complete button 6b), the monitor screen changes to that shown in Fig. 20 after checking inside the bus. This monitor screen is similar to the monitor screen in the bus monitoring mode shown in Fig. 18, and the background of the lower column Hd of the display frame column H changes to green (dot hatching), for example, and displays the message "Monitoring to see if there are any people inside the bus." In other words, the system returns to the bus monitoring mode and monitors inside the bus.

[0137] In this way, in this embodiment 1, by continuing the in-bus monitoring mode, even if there are children inside the bus, they can be reliably detected, and it is possible to reliably prevent children from being left behind until the power in the standby power source 7 runs out.

[0138] As described above, this embodiment 1 is an imaging system for a vehicle in which a large number of children get on and off, and comprises a first camera 4 installed in a position inside the vehicle where it can capture images of the boarding and alighting area C where the children get on and off and the seats Sb, Sc where the children sit, with the same angle of view, and a control box 2 that controls the first camera 4 to be used in a boarding and alighting number counting mode that counts the number of children while the vehicle is in operation, and to be used in an in-bus monitoring mode that captures and monitors the interior of the vehicle after the engine is stopped after the vehicle is no longer in operation.

[0139] As a result, the control box 2 uses the first camera 4 in a boarding / alighting counting mode for counting the number of passengers while the vehicle is in operation, and in a bus interior monitoring mode for photographing and monitoring the interior of the vehicle after the engine is stopped after the vehicle is in operation.

[0140] Therefore, the first camera 4 can perform both the counting function of counting the number of children getting on and off the vehicle, and the interior monitoring function of photographing and monitoring the interior of the vehicle.

[0141] Therefore, the photographing system M for vehicles in which a large number of children get on and off can count the number of children getting on and off the vehicle, photograph and monitor the condition inside the vehicle, and do this with as few cameras as possible, thereby promoting the spread of photographing systems for vehicles.

[0142] In addition, in this embodiment 1, a second camera 5 is installed in a position inside the vehicle where it can photograph the seats Sb, Sc in which the children are seated, and the first camera 4 is installed at the upper part of the left side of the vehicle interior BR, while the second camera 5 is installed at the upper part of the right side of the vehicle interior, diagonally opposite the first camera 4 and offset in the fore-and-aft direction of the vehicle.

[0143] This allows the vehicle interior BR to be photographed while minimizing blind spots caused by the backrests of the seats Sb, Sc, etc., between the angle of view photographed by the first camera 4 and the angle of view photographed by the second camera 5.

[0144] In other words, the first camera 4 and the second camera 5 are positioned diagonally opposite each other on both the left and right sides of the vehicle interior BR, so that even in a long interior space where multiple seats Sb, Sc are lined up in the fore-aft direction of the vehicle, blind spots caused by the backrests of the seats Sb, Sc are not created and the entire vehicle interior BR can be photographed.

[0145] Therefore, with only two cameras, the first camera 4 and the second camera 5, it is possible to capture and monitor the entire interior BR of the vehicle, which is long in the vehicle front-rear direction, without any blind spots.

[0146] Therefore, the entire interior of the vehicle BR, which is long in the fore-and-aft direction, can be captured without any blind spots using a small number of cameras, so that the number of cameras can be reduced while maintaining the surveillance performance when using cameras in the bus surveillance mode.

[0147] In addition, this embodiment 1 is equipped with an in-vehicle monitor 1 that displays a first image G4 captured by the first camera 4 and a second image G5 captured by the second camera 5 on the same screen, and a control box 2 that displays the first image G4 displayed on the in-vehicle monitor 1 in a left-right inverted manner.

[0148] As a result, the first image G4 and the second image G5 have opposite orientations in the fore-and-aft direction of the vehicle interior BR because the first camera 4 and the second camera 5 are installed in different positions on the left and right sides of the vehicle interior. However, by displaying the first image G4 in a mirror-inverted manner, the fore-and-aft direction of the vehicle is displayed as an image with the same orientation.

[0149] Therefore, the driver or the like viewing the monitor screen of the in-vehicle monitor 1 can check the first image G4 and the second image G5 without feeling any discomfort.

[0150] In other words, the driver etc. checks the status of the children getting on and off on the in-vehicle monitor 1, but if the front-to-back orientation of the first image G4 and the second image G5 are reversed, it will be difficult to tell at a glance whether the children are getting on or off. Therefore, by flipping the first image G4 left to right, the driver etc. will not feel this sense of incongruity.

[0151] This eliminates the awkward look on the monitor screen that occurs when the first camera 4 and the second camera 5 are installed in separate positions on the left and right sides of the vehicle, allowing the driver, etc. to accurately check the situation of the children, etc.

[0152] In this embodiment 1, the first image G4 is flipped left to right, but the same effect can be obtained by flipping the second image G4 left to right, so either image may be used for left-right determination.

[0153] In the first embodiment, the installation position of the first camera 4 is set at the upper part of the left side surface of the boarding / disembarking section C where the boarding / disembarking door Cb is provided.

[0154] This allows the first camera 4 to capture an image of the head of a child getting on and off at the boarding and alighting section C, thereby enabling detection of the child.

[0155] Therefore, when the first camera 4 photographs the children and counts the number of children, the children do not overlap each other, so the number of children can be counted accurately.

[0156] Therefore, the mode of counting the number of passengers getting on and off using the first camera 4 can be made to function with greater accuracy.

[0157] (Embodiment 2) Next, the second embodiment will be described with reference to Fig. 21 and Fig. 22. Fig. 21 is an overall plan view of the interior of a bus in which the vehicle imaging system of the second embodiment is arranged, and Fig. 22 is a diagram of a monitor screen displayed on an in-vehicle monitor, corresponding to Fig. 9 of the first embodiment.

[0158] The vehicle photography system of this embodiment 2 is different from that of embodiment 1 in that the installation position of the first camera 14 in the vehicle interior BR and the installation position of the second camera 15 in the vehicle interior BR are different from those of embodiment 1. Furthermore, since the installation position of the first camera 14 is different, the passing determination line 1Lg is also set at a different position.

[0159] The other components are the same as those in the first embodiment, so they are given the same reference numerals and the description is omitted.

[0160] First, the first camera 14 is installed above the second row seats Sb on the right side of the vehicle interior so as to be able to photograph the boarding and alighting area C, specifically, the boarding and alighting door Ca, from the front.

[0161] The second camera 15 is installed above the rearmost seat Sc on the right side of the vehicle interior BR. In other words, the second camera 15 is installed diagonally opposite the first camera 14 and shifted in the front-rear direction of the vehicle.

[0162] Furthermore, the passage determination line 1Lg is configured as a horizontal line set at the boundary position of the recessed portion Cd of the boarding / alighting portion C (the corner portion between the recessed portion Cd and the floor surface Bf).

[0163] In this embodiment 2, as in embodiment 1, when the occupant detection frame Pm as a person exceeds this passing judgment line 1Lg from top to bottom, it is judged that the occupant has boarded the vehicle, and when the occupant detection frame Pm exceeds it from bottom to top, it is judged that the occupant has disembarked.

[0164] In this embodiment 2, the movement of a person's entire body is captured and they are detected as one person, so when the feet of a person (Pm) cross the passing judgment line 1Lg from top to bottom or from bottom to top, it is determined that the person is boarding or disembarking.

[0165] Furthermore, in this embodiment 2, the installation positions of the first camera 14 and the second camera 15 are different from those of the first camera 4 and the second camera 5 in embodiment 1, and therefore the first image G14 captured by the first camera 14 and the second image G15 captured by the second camera 15 are different from the first image G4 and the second image G5 in embodiment 1.

[0166] That is, the first image G14 and the second image G15 in the second embodiment are photographed in the opposite direction to the first image G4 and the second image G5 in the first embodiment, and therefore the photographed angle of view is also opposite.

[0167] However, since both the first camera 14 and the second camera 15 are configured as semi-spherical cameras with a 360° angle of view, the boarding and disembarking area C and the seats Sb, Sc are captured from both angles of view.

[0168] Since the second embodiment thus configured has substantially the same configuration as the first embodiment, it provides substantially the same effects and advantages.

[0169] However, in the case of embodiment 2, as shown in Figure 22, the first image G14 can capture a frontal image of the child getting on, so the driver, etc. can check who is getting on and what their condition is by simply looking at the in-car monitor 1.

[0170] Therefore, the driver can check the status of each child simply by looking at the in-car monitor 1.

[0171] Therefore, the driver can know who is attending or absent by the number of children boarding the school bus B. The driver can also know the physical condition of each child.

[0172] Furthermore, if a control unit with advanced AI image recognition technology is used, it will be possible to have the vehicle's photography system record who is riding on school bus B.

[0173] (Other embodiments) Next, other embodiments will be described.

[0174] First, the first camera 4, 14 and the second camera 5, 15 do not necessarily have to be semi-spherical cameras with a 360° angle of view. Any camera may be used as long as it has an angle of view that simultaneously captures at least the boarding and disembarking area C and the seats Sb and Sc.

[0175] Furthermore, the installation positions of the first camera 4, 14 and the second camera 5, 15 are not limited to the top of the left window glass BW1 or the top of the right window glass BW1, etc., as long as they are above the auxiliary seat Sd or above the seat Sb, etc., and they may be fixed, for example, to the left end or right end of the roof trim BT, which serves as the ceiling, via a fixing member not shown.

[0176] Furthermore, in the first and second embodiments, the confirmation button 6 is provided, but the confirmation button 6 may be omitted.

[0177] In addition, in the confirmation button 6 of the first and second embodiments, the completion button 6b is simply used to stop the alert, but by pressing the shutter button 6a at the same time as the completion button 6b, a still image taken at the time the alert is stopped may be stored in a storage means or the like or transmitted to the staff room monitor 11.

[0178] Furthermore, in the first and second embodiments, electricity is supplied from the standby power supply 7 after the engine is stopped, but it is also possible to directly receive electricity from the on-board power supply without using the standby power supply 7. In this case, however, it is desirable to set a timer or the like to cut off the electricity supply from the on-board power supply after a certain time has elapsed so as not to deteriorate the running performance of the vehicle, such as starting the vehicle.

[0179] In the first and second embodiments, the vehicle photography system is implemented in the school bus B, but the vehicle photography system may also be implemented in other vehicles, such as general route buses, tourist buses, school buses, and commuter buses, and furthermore, it is not limited to buses and may be implemented in vehicles such as trains. [Industrial Applicability]

[0180] As described above, the present invention is useful for an imaging system for vehicles with a large number of passengers getting on and off, such as a bus or a train, and in particular for an imaging system for a vehicle that captures images of the interior of the vehicle, counts the number of passengers getting on and off, and monitors the interior of the vehicle.
