  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a configuration diagram of an illegal parking monitoring system. In FIG. 1, the illegal parking monitoring system 10 in this embodiment is provided with a camera device CA (see also FIG. 5) that captures a parking prohibited area PPA. A caution device ST including sound generation means STV that emits a caution sound in response to a signal is arranged. The example of the attention device ST here is described in FIG. 1 and FIG. 5 as a signboard-like shape having a warning mark. The camera server 3 connected to the camera device CA and placed in the vicinity thereof has an image and information receiving / transmitting means 31 for receiving and transmitting images and information of the camera device CA, and a control means 33 for controlling the receiving and transmitting status, the camera posture, and the like. Have

  The monitoring server 5 is connected to the image and information transmission / reception means 31 of the camera server 3 via any one of the Internet 4 such as FOMA (registered trademark) net, an intranet, and a direct connection line. Here, a case using the Internet 4 is illustrated.

  The monitoring server 5 includes an image of the camera server 3 and an image and information receiving means 51 for receiving an image and information signal from the information receiving / transmitting means 31, and an illegal parking for determining illegal parking from these images and information signal. The wheel determination means 53 and the attention voice instruction means 55 which receives this determination and sends a warning voice issue instruction to the attention device ST. Furthermore, the illegal parking determination means 53 is provided with display means 57 for displaying this output and dispatch command sending means 56 for sending a dispatch command to the supervisor. The dispatch command transmission means 56 receives information on illegal parking more than a preset number from the illegal parking determination means 53 and sends a dispatch instruction signal to the mobile terminal 7 of the supervisor. The supervisor who received the signal 59 from the dispatch command transmission means 56 at the portable terminal 7 or the like will be dispatched to the parking prohibition area PPA. If the mobile terminal 7 is a FOMA (registered trademark) terminal, an image is added to the signal from the dispatch command transmission means 56, and a signal and an image signal to the monitoring instructor's mobile terminal 7 via the FOMA (registered trademark) net. Can be sent.

  Further, as shown in FIG. 2, the illegal parking determination unit 53 includes a still image acquisition unit 53a that receives images and information from the image and information reception unit and acquires still images at predetermined time intervals, and A motorcycle image discrimination recognition unit 53b for discriminating and recognizing a motorcycle image on a still image, a discrimination result image recording unit 53c for recording the discrimination result images recognized and recognized in time series, and comparing and comparing the discrimination result images A discrimination result image comparison means 53d showing a difference, a new parking discrimination means 53e for judging a new illegal parking based on the result from the discrimination result image comparison means 53d, and an illegal stop number counting means 53f. .

  Next, the operation of this monitoring system will be described. The parking area PPA is copied by the camera apparatus CA, and the image and information of the camera apparatus CA are received by the image and information transmission / reception means 31 of the camera server. This image and information are transmitted to the monitoring server 5 via the Internet 4.

  The image of the monitoring server 5 and the image of the camera server 3 received by the information receiving means 51 and the image and information from the information receiving / transmitting means 31 are an image for determining illegal parking by the illegal parking determination means 53, and Information. In response to this determination, the caution voice instruction means 55 of the monitoring server 5 sends a caution voice issue instruction to the caution device ST disposed in or near the parking prohibition area PPA when illegal parking occurs. .

  In the above process, the illegal parking determination unit 53 receives the image and the information signal from the image and information receiving unit 51, and acquires the still image at a predetermined time interval, in this example, every 5 seconds, by the still image acquiring unit 53a. To do. The two-wheeled vehicle image on the still image is discriminated and recognized by the two-wheeled vehicle image discriminating / recognizing means 53b. The discrimination result image recording means 53c records the discrimination result images that are recognized and recognized and focused on the two-wheeled vehicle in time series. The discrimination result image comparison means 53d compares and compares the discrimination result images and outputs the difference as a judgment value. In response to the result from the discrimination result image comparison unit 53d, the new parking determination unit 53e determines the newly added illegal parking, and gives a result signal to the caution voice instruction unit 55 through the line 55a. In addition, it is desirable to provide a periodic operation instruction signal from the illegal parking determination means 53 through the line 55b at a certain time interval in the caution voice instruction means 55.

  The attention voice issuing instruction signal from the attention voice instruction means 55 is transmitted to the camera apparatus CA through the line 55c, the Internet 4, and the camera server 3 through the line 55d. The camera device CA transmits this instruction signal to the attention device ST in this example wirelessly. The attention device ST sends a voice message to the bicycle parking prohibited area PPA.

  On the other hand, the illegal parking number counting unit 53f of the illegal parking determination unit 53 receives the signal of the current discrimination result image from the discrimination result image recording unit 53c, and calculates the illegal stop number from the image to the parking prohibited area PPA. When the count exceeds a predetermined count, for example, 10 units, a dispatch command signal is sent from the dispatch command transmission means 56 to the mobile terminal 7 of the supervisor. It is possible to monitor and eliminate illegal bicycle parking efficiently by dispatching a supervisor.

  Next, the operation principle of the illegal parking determination means 53 for determining new illegal parking will be described in more detail with reference to FIGS.

  Here, the discrimination result image comparison means 53d is a new illegal one based on the comparison between the discrimination result image G1 and the previous discrimination result image G2 among the discrimination result images at intervals of 5 seconds from the discrimination result image recording means 53c. When it is determined that there is a bicycle parking candidate, it is further determined whether the bicycle is illegally parked based on the comparison result between the previous determination result image G2 and the current determination result image G3.

  FIG. 3 is an operation principle explanatory diagram showing a case where a new illegal parking is found, and a discrimination result image at intervals of 5 seconds is recorded in the discrimination result image recording means 53c. In particular, for each determination, a determination result image G1, a determination result image G2, and a determination result image G3 are required. The discrimination result image comparison means 53d first compares the discrimination result image G1 with the previous discrimination result image G2 and finds a candidate image g2 with the possibility of parking at a new position, and sets the determination value V1 to 1. When the determination value V1 is 1, in the next stage, the previous determination result image G2 and the current determination result image G3 are compared, and if the candidate image g2 remains as the image g3, the determination result image comparison unit 53d. The determination value V2 is 1. If the image g3 is missing from the current determination result image G3, the determination value V2 is zero. Only when the determination values V1 and V2 are both 1, the new parking determination means 53e determines that there is a new illegal parking. Upon receiving this determination signal, the caution voice instruction means 55 transmits a caution voice issue instruction signal to the attention device ST.

  Next, the operation principle when there is no new illegal parking is described with reference to FIG. In this example, when the discrimination result image comparison unit 53d compares the discrimination result image G1 with the previous discrimination result image G2, the number of parked bicycles in the image is reduced. In this case, the determination value V1 is 0 because the bicycle that has been parked is gone. If the determination value V1 at this stage is 0, it is determined that there is no new illegal parking without comparing the previous determination result image G2 and the current determination result image G3, or the determination value V2 is automatically set to 0. As a result, the new parking determination means 53e determines that there is no new illegal parking. In this case, even if there is a possibility that a new illegal bicycle parking candidate can be found as shown in FIG. 4 by comparing the previous discrimination result image G2 and the current discrimination result image G3, this is appropriate in the next discrimination stage. Processing is performed. That is, in the next stage, the current previous discrimination result image becomes the previous discrimination result image, and the current current discrimination result image becomes the previous discrimination result image.

  Furthermore, FIG. 5 has shown the external view of the bicycle parking lot as one embodiment by this invention. In FIG. 5, the solar cell SC is disposed on the road surface of the no-parking area PPA, and the camera device CA, the attention devices ST1 and ST2, and their signs and lighting are driven by an independent power source by solar power generation. ing. Thereby, the caution message can be effectively transmitted by light and voice. In addition, the attention device is configured to receive an instruction to issue a caution voice wirelessly from the camera device CA, and a plurality of devices, here two devices, increase the attention effect. As a result, the degree of freedom of the establishment location of the camera device CA and the attention devices ST1 and ST2 is increased, the area can be changed, and wiring such as a power cable and a communication cable can be reduced. In addition, it is possible to provide a self-sustained power source with a larger area and a larger amount of power generation by placing the solar battery SC on the road surface of the bicycle parking prohibited area PPA and using it as at least part of the self-sustained power source.

  In addition, since it is based on the camera device, the area on the screen can be freely set. Further, since the attention device is used, the message can be changed by dividing the area. It is also possible to change the message after starting operation.

  As described above, the illegal parking monitoring system and method according to the present invention are useful as a system method that can reduce the labor and burden costs of illegal parking control, which has been a problem in many regions. Suitable for plaza surveillance control.
