Description

  The present invention relates to a parking lot monitoring system that monitors vehicles in a parking lot.

Conventionally, as a parking lot monitoring system, for example, there is one that determines the presence of a vehicle in each parking lot by processing an image of a camera installed in a parking lot, and measures the degree of congestion in the parking lot (for example, Patent Document 1).
In addition, there has been a vehicle crime prevention device that detects mischief or theft of a vehicle using an in-vehicle device (for example, see Patent Document 2).

Japanese Patent Laid-Open No. 9-67954 JP 2006-107279 A

However, as a conventional vehicle monitoring system using image processing, it is possible to detect the presence of vehicles in each parking lot of a parking lot and measure the degree of congestion in the parking lot. Because it cannot be identified, it could not be used as a security device.
In addition, in a crime prevention system that detects vehicle theft or mischief by an in-vehicle device, it is necessary to mount the device for each vehicle, so that a vehicle that does not have the in-vehicle device cannot be monitored. In addition, when configuring a system that detects vehicle theft or mischief by an in-vehicle device, providing the communication means in the in-vehicle device itself increases the cost of the device per vehicle and increases the burden on the user. There was also.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a parking lot monitoring system capable of detecting fraudulent acts such as suspicious person behavior and vehicle theft.

  A parking lot monitoring system according to the present invention includes a video acquisition device that acquires an image of a parking lot to be monitored in a parking lot, a personal authentication unit that is installed in a parking lot and authenticates a user, and a personal authentication unit Based on user authentication, sets or cancels the warning state of the parking lot corresponding to the user, and determines whether there is an abnormality in the warning lot based on the image acquired by the video acquisition device And an abnormality notifying means for reporting the occurrence of an abnormality to an information terminal registered in advance when the abnormality is determined by the abnormality determining means.

  The parking lot monitoring system according to the present invention sets or cancels the warning state of the parking lot according to the user's authentication state, and when the abnormality determining means determines that there is an abnormality when in the warning state, the pre-registered information terminal Since the notification is made, it is possible to detect fraudulent acts such as suspicious behavior and vehicle theft.

Embodiment 1 FIG.
1 is a block diagram showing a parking lot monitoring system according to Embodiment 1 of the present invention.
In the figure, the parking lot monitoring system includes a video acquisition device 1, a personal authentication unit 2, an ID card 3, a video storage device 4, an abnormality determination unit 5, an abnormality notification unit 6, a network 7 and an information terminal 8.
The video acquisition device 1 is a device that is installed in a parking lot and includes a camera or the like for taking a video including a parking lot to be monitored in the field of view. The personal authentication unit 2 is a unit that is installed near, for example, the entrance of a parking lot and authenticates the user 9. This personal authentication means 2 reads the ID (user identification information) of the user 9 from the ID card 3 possessed by the user 9 and the registrant ID management table 21 stores this read ID. Authentication is performed by collating with the ID. The registrant ID management table 21 shows a correspondence relationship between a parking lot in a parking lot and a registrant (regular user) of the parking lot, and a plurality of registrants are permitted for one parking lot. When there is a plurality of IDs, a plurality of IDs are registered for one parking lot.

  The video storage device 4 is a device for storing the video obtained from the video acquisition device 1. Based on the authentication result of the user 9 obtained from the personal authentication unit 2, the abnormality determination unit 5 sets and cancels the alert state (alert mode). When the alert mode is set, the video acquisition device 1 It is a means to make an abnormality determination based on the obtained video, and when a suspicious behavior of a person and movement of a vehicle are detected in a parking lot in which a warning mode is set, an abnormality has occurred in the corresponding parking lot It is comprised so that it may determine. Here, as means for detecting a person's suspicious behavior, for example, the method described in Japanese Patent Application Laid-Open No. 2003-169319 is used, and the person moves around or stays around the corresponding parking lot for a predetermined time or more. It is determined that the behavior is suspicious when a situation is detected. As a means for detecting the movement of the vehicle, for example, a method described in Patent Document 1 can be applied.

  The abnormality reporting unit 6 is a unit for reporting to the information terminal 8 registered in advance via the network 7 when the abnormality determining unit 5 determines that an abnormality has occurred. Here, the network 7 is the Internet, for example, and the information terminal 8 is a mobile terminal possessed by the user 9 such as a mobile phone having a function of connecting to the Internet. Then, a mail that can be confirmed by the user 9 is used as a notification means, and an image taken by the video acquisition device 1 and including the corresponding parking lot is attached to the notification mail. As an image to be attached, when the abnormality determination means 5 detects a suspicious person, it captures a situation where a person is moving around or stays around the corresponding parking lot, and when a vehicle movement is detected. What photographed the parking lot after a vehicle movement is desirable.

FIG. 2 is an explanatory diagram showing a flow of use of the parking lot monitoring system according to the first embodiment of the present invention. In the figure, an operation indicated by a rectangle indicates an operation (operation) performed by a user (registrant) 9, an operation indicated by a parallelogram indicates an operation performed by the system, and an operation indicated by an ellipse indicates a parking lot state.
First, the procedure for entering a vehicle into an empty parking lot will be described. When the parking lot is in the empty vehicle state 101, the alert state of the corresponding parking lot is released. In this state, it is assumed that the user 9 enters the vehicle into the registered parking lot (102). Then, the user 9 performs an authentication operation 103. As a result, the system sets a warning state for the corresponding parking lot, and starts an abnormality detection process 104 by image processing. The corresponding parking lot is in the in-vehicle state 105.
The procedure for unloading a vehicle from a parked lot is as follows. Since a warning state is set for the parking lot in the vehicle presence state 105, the user 9 first performs an authentication operation 106. As a result, the system releases the warning state for the corresponding parking lot and stops the abnormality detection process (107). Thereafter, the user 9 performs the vehicle exit 108. As a result, the corresponding parking lot becomes an empty vehicle state 101.

  When the vehicle is present (105), if the user is a regular user 9, that is, a registrant, the corresponding parking lot is obtained by performing the authentication operation 106 before the registrant approaches the vehicle or moves the vehicle. Can be released. However, if the abnormality determination means 5 detects that the person is wandering or staying around the corresponding parking lot or the vehicle of the corresponding parking lot has moved in the on-vehicle state 105 where the warning state is set, The system determines that these actions are due to non-registrants, and notifies the registrant's information terminal 8 that an abnormality has occurred via the abnormality notification means 6.

FIG. 3 is a diagram illustrating an operation of the abnormality determination unit 5 of the parking lot monitoring system according to the first embodiment.
If a warning state is set for the parking lot, it is checked whether or not an abnormality has occurred (step ST201). First, it is checked whether or not suspicious behavior such as wandering or staying of a suspicious person is occurring in the corresponding parking lot (step ST202). Such suspicious behavior such as wandering and staying is determined by whether or not a person is detected for a predetermined time or more near the parking lot.
If the suspicious behavior is detected, the abnormality determination means 5 instructs the abnormality reporting means 6 to notify the registrant that the suspicious behavior has been detected (step ST203). Thereafter, it is checked whether or not the vehicle parked in the corresponding parking lot is moving (step ST204). If the movement of the vehicle is detected, the abnormality determination means 5 instructs the abnormality notification means 6 to notify the registrant that the movement of the vehicle has been detected (step ST205). Note that the series of processes in FIG. 3 is repeatedly executed at regular time intervals for each parking lot to be monitored by the system.

  Here, the video storage device 4 may record only when it is determined to be abnormal by the abnormality determining means 5, but may be recorded only when it is set in a warning state by the personal authentication means 2. Further, it may always be recorded regardless of the alert state setting. When always recording, the video storage device 4 records the time when the abnormality determining means 5 determines that there is an abnormality, and the contents of the abnormality (suspicious behavior or vehicle movement, and the number of the parking lot where the abnormality occurred). Is desirable.

  Thus, in this Embodiment, since the personal authentication means 2 for setting a warning state independently for every parking lot is provided, a warning state is set to the parking lot, and an abnormal state is set. It can be made to function as a security device for notifying a registrant only when an error is detected. Furthermore, in this embodiment, since the vehicle is monitored from the outside of the vehicle without using the in-vehicle device, any vehicle not equipped with special equipment can be monitored, and the burden on the user can be reduced. Moreover, since the abnormality determination means 5 determines abnormality using the image | video image | photographed with the image | video acquisition apparatus 1 which contains a some parking lot in a visual field, cost reduction of a system can be achieved. Moreover, since the abnormality determination means 5 detects an abnormality using the video imaged from the outside of the vehicle, it can not only detect the vandalism and theft of the vehicle, but also suspicious behavior such as approaching the monitored vehicle and scolding the inside of the vehicle. Can be detected.

  In the present embodiment, since the video acquisition device 1 and the video storage device 4 are provided, for example, when a criminal act such as vehicle theft occurs, the vehicle is moved after the thief appears in the parking lot. In addition to accumulating a series of videos up to that time, it is also possible to reproduce and confirm the accumulated video later, so that the situation where the criminal act has occurred can be surely grasped. Further, when the abnormality determining means 5 determines that there is an abnormality, the abnormality notifying means 6 for notifying the registrant with an image including the corresponding parking lot in the field of view and capturing the situation at the time of occurrence of the abnormality detected by the system. With this, it is possible to immediately and reliably notify the registrant of the situation at the time of occurrence of an abnormality.
