  In the system described in Patent Literature 1, a parking position sensor is provided above a parked vehicle for each vehicle compartment, and a headlight is installed on a pillar that is a boundary between blocks on one side of a lane. . The system described in Patent Literature 1 has a large work load when installing a parking position sensor and a headlight. Specifically, since the parking position sensor needs to be installed for each vehicle compartment, the installation of the parking position sensor requires work for the number of vehicle rooms, and the number of work steps is large. In addition, the installation work of the lighting is also required. Further, when replacing a part of the parking position sensor and the blinking light of the existing system, it is necessary to prohibit entry of the vehicle into the target lane and make the vehicle room empty. For this reason, work is often performed at night in consideration of the convenience of the parking lot user, but the work at night has a heavy burden on the worker. In addition, even during the night when the parking lot is closed, the vehicle may be parked in the vehicle compartment, and the installation of the parking position sensor cannot be performed. As described above, in the system described in Patent Literature 1, since the degree of freedom of the installation work is low, the load on the worker is large, and reduction of the work load has been desired.

  In the technique described in Patent Document 2, a plurality of passenger compartments are photographed by a monitoring camera, and the number of devices related to detecting the presence or absence of parking in the plurality of passenger compartments may be smaller than that described in Patent Document 1. . However, Patent Literature 2 does not mention the installation of the lamp.

  Against the background described above, for example, in a parking lot that requires a blinking light such as a medium-sized or large-sized parking lot, both a sensor and a blinking light that detect the presence or absence of a parked vehicle in the vehicle compartment are used. There has been a demand for a system that can reduce the load of installation of the system.

  The present invention has been made in view of the above-described problems, and reduces the load of installation work of a device that detects a parked vehicle in a plurality of compartments and a device that displays information about the parked vehicle in the compartments. The present invention provides a parking lot management system that can be used.

  A parking lot management system according to the present invention captures an image of a block including a vehicle path and a plurality of vehicle rooms provided on both sides of the vehicle road, and outputs a video signal of the plurality of vehicle rooms. And a display device that is provided in the block and that changes a display state when it is determined based on a video signal output from the camera that the vehicle is parked in all of the plurality of compartments. It is provided.

  According to the present invention, since one monitoring camera and one display device may be installed in a block including a vehicle path and a plurality of vehicle compartments provided on both sides thereof, the installation work load is reduced.

(Configuration of parking lot management system)
FIG. 4 is a system configuration diagram of the parking lot management system according to the first embodiment. The parking lot management system 10 includes a monitoring display device 1 and a control device 30. Furthermore, the parking lot management system 10 of the present embodiment includes a power supply device 20 that supplies power to the monitoring display device 1. The monitoring display device 1 and the power supply device 20 are connected by a LAN (Local Area Network) cable 21 which is a communication cable. The power supply device 20 and the control device 30 are communicatively connected by a communication line 22. The monitoring display device 1 according to the present embodiment supports PoE (Power over Ethernet (registered trademark)).

  The monitoring display device 1 includes a camera 2, a display device 3, a power receiving circuit 4, and a communication circuit 5. The power receiving circuit 4 receives PoE power from the power supply device 20 via the LAN cable 21, converts a voltage from the power supply device 20 into a predetermined voltage, and applies the voltage to the camera 2 and the display device 3. The communication circuit 5 receives communication data input via the LAN cable 21 and outputs a control signal corresponding to the received communication data to the camera 2 and the display device 3. Further, the image signal of the image captured by the camera 2 is transmitted to the LAN cable 21.

  In the present embodiment, the power supply device 20 is a device that supplies PoE to the monitoring display device 1 and a device that relays communication between the monitoring display device 1 and the control device 30. The power supply device 20 is connected to the monitoring display device 1 via a LAN cable 21 and is connected to the control device 30 via a communication line 22. The communication line 22 only needs to be able to transmit and receive signals between the control device 30 and the power supply device 20.

  The control device 30 includes a communication unit 31, an image processing unit 32, a control unit 33, and a memory 34. The communication unit 31 is a circuit that receives a signal input via the communication line 22 and transmits a signal to the communication line 22. The control device 30 includes, for example, a personal computer, a server device, and the like.

  The image processing unit 32 performs image processing on the video signal transmitted from the monitoring display device 1 so that the control unit 33 can determine whether or not the vehicle is parked in each of the vehicle rooms 111 to 116. . The image processing unit 32 according to the present embodiment processes the input video signal and extracts image information of the vehicle interior display 118 provided in the vehicle interiors 111 to 116 in the block 100. Then, the extracted image information of the cabin display 118 is output to the control unit 33.

  The control unit 33 determines whether or not each of the passenger compartments 111 to 116 is parked based on the information input from the image processing unit 32.

  The control unit 33 is configured by dedicated hardware or a microcomputer having a memory and a CPU executing a program stored in the memory. When the control unit 33 is dedicated hardware, the control unit 33 corresponds to, for example, a single circuit, an ASIC (Application Specific Integrated Circuit), an FPGA (Field-Programmable Gate Array), or a combination thereof. Each of the function units realized by the control unit 33 may be realized by individual hardware, or each function unit may be realized by one piece of hardware. When the control unit 33 is a microcomputer, each function executed by the control unit 33 is realized by the CPU reading and executing a program stored in the memory. Here, the memory is, for example, a nonvolatile or volatile semiconductor memory such as a RAM, a ROM, a flash memory, an EPROM, and an EEPROM.

  The memory 34 stores data used when the image processing unit 32 performs image processing and data used when the control unit 33 determines whether or not the vehicle is parked in the passenger compartments 111 to 116. The memory 34 stores images of the vehicle interiors 111 to 116 in the block 100 when not parked as basic images. This basic image includes a cabin display 118 of each of the cabin 111 to 116. The control unit 33 collates the information of the cabin display 118 extracted by the image processing unit 32 with the cabin display 118 of the basic image. Then, when the compartment display 118 in the basic image is not extracted, it is determined that the compartment display 118 is covered, that is, the vehicle is parked in the corresponding compartment. On the other hand, when the cabin display 118 in the basic image is extracted by the image processing unit 32, it is determined that the vehicle is not parked on the cabin display 118, that is, the corresponding cabin is empty. I do.

  In addition, the method of determining the parking situation in the passenger compartments 111 to 116 by the image processing unit 32 and the control unit 33 is not limited to the method illustrated here. Any method can be used as long as it can determine whether or not the vehicle is parked in the vehicle interiors 111 to 116 based on the video signal transmitted from the camera 2 which is an omnidirectional camera. For example, a mark for image recognition is displayed in the vehicle compartments 111 to 116 instead of the vehicle compartment display 118. The mark for image recognition may be the same mark provided that it is provided in each of the passenger compartments 111 to 116. Then, the image in the case where all of the vehicle interiors 111 to 116 are empty is stored in the memory 34 as a basic image. The image processing unit 32 collates the basic image with the image from the camera 2. If the image recognition mark in the basic image is also present in the image from the camera 2, the control unit 33 determines that any of the vehicle compartments 111 to 116 is vacant. It is determined that the vehicle is parked at １１６116, that is, the block 100 is full.

  In addition, for example, the image processing unit 32 performs image recognition of the license plates of the vehicles in the vehicle interiors 111 to 116. When the license plate is recognized for the number of the vehicle compartments 111 to 116, the control device 30 determines that the vehicle is full and the number of recognized license plates is larger than the number of the vehicle compartments 111 to 116. When the number is small, it is determined that one of the vehicle compartments 111 to 116 is empty.

  The control unit 33 outputs a control signal related to display on the display device 3 based on the determination result of the parking situation in the vehicle interiors 111 to 116 in the block 100.

(Operation of the parking lot management system 10)
As illustrated in FIG. 1, it is assumed that the vehicle 200 is parked only in the passenger compartment 112. In this case, the monitoring display device 1 transmits the video signal captured by the camera 2 to the control device 30 via the LAN cable 21, the power supply device 20, and the communication line 22 in real time. The camera 2 is an omnidirectional camera, and a video signal obtained by imaging all of the road 103 and the cabs 111 to 116 in the block 100 is transmitted to the control device 30. The control device 30 determines whether or not the vehicle is parked in all of the vehicle interiors 111 to 116 in the block 100 based on the video signal from the camera 2.

  When the vehicle is not parked in any of the passenger compartments 111 to 116, that is, when there is an empty space in the block 100, the control device 30 transmits a control signal instructing display in the second display state to the communication unit 31. Output to the communication line 22 via the In the example of FIG. 1, since the vehicle is not parked outside the vehicle room 112, a control signal instructing display in the second display state is output to the communication line 22. The control signal output to the communication line 22 is relayed to the power supply device 20, flows through the LAN cable 21, and is received by the communication circuit 5 of the monitor display device 1. The display device 3 performs display in the second display state based on the received control signal.

  On the other hand, when the vehicle is parked in all of the passenger compartments 111 to 116, that is, when it is detected that the inside of the block 100 is full, the control device 30 performs control to instruct display in the first display state. The signal is output to the communication line 22 via the communication unit 31. The control signal output to the communication line 22 is relayed to the power supply device 20, flows through the LAN cable 21, and is received by the communication circuit 5 of the monitor display device 1. The display device 3 performs display in the first display state based on the received control signal. When any of the compartments 111 to 116 in the block 100 shown in FIG. 1 is empty and the display device 3 is performing display in the second display state, the compartments 111 to 116 may be full. When it is detected, the display device 3 changes the display from the second display state to the first display state.

  As shown in FIG. 1, one monitoring display device 1 having a function as a headlight is provided in a block 100. For this reason, the driver who has entered or is about to enter the block 100 can determine whether or not there is a free space in the block 100 by focusing only on one monitoring display device 1. . Since the objects to be focused on are narrowed down, the driver can easily find the empty block 100 and can easily drive in the parking lot.

  Further, in the present embodiment, monitoring display device 1 is installed on lane 103. For this reason, when the driver who passes through the lane 103 looks straight at the traveling direction, the monitoring display device 1 easily enters the field of view. Therefore, movement of the driver's line of sight to the left and right for checking the monitoring display device 1 as a blinking light is suppressed, and the burden of the driver's visual recognition is reduced.

  In the monitoring display device 1 according to the present embodiment, the camera 2 and the display device 3 are integrally formed. For this reason, when installing the monitoring display device 1 in a parking lot, it is sufficient to install one integrated device. Therefore, the work load related to the installation of the monitoring display device 1 is reduced. When a sensor for determining the presence or absence of parking is provided for each vehicle compartment as in the related art, installation of the sensor requires installation work for the number of vehicle compartments. In addition to the installation work, the installation work of the lighting was also necessary. For this reason, the installation of the sensor and the blinking light puts a heavy burden on the installation worker. In particular, when the existing parking lot is renewed, there are situations where a parked vehicle is present in the vehicle compartment, and the timing at which the installation work can be performed is sometimes limited. However, according to the present embodiment, only the monitoring and display device 1 needs to be installed for each block 100 of the parking lot, and the burden on the installation worker is reduced.

  Further, the monitoring display device 1 of the present embodiment is installed on the road 103. Therefore, when the monitoring display device 1 is installed in an existing parking lot, it is only necessary to stop the vehicle from entering the corresponding lane 103 only. Even if the vehicle 200 is parked in any of the passenger compartments 111 to 116, the work of installing the monitoring display device 1 on the lane 103 hardly hinders the installation of the monitoring display device 1 in time. Increased degrees of freedom and environmental freedom.

  Furthermore, in the parking lot management system 10 of the present embodiment, the monitoring display device 1 receives PoE power. A LAN cable 21 may be connected to the monitoring display device 1. Since both power supply and communication are realized by the LAN cable 21, wiring work when installing the monitoring display device 1 in a parking lot is easy.
