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

  A system configuration according to an embodiment of the present invention will be described with reference to FIG. In this embodiment, a camera 101, a prefectural police headquarters server 102, a vehicle monitoring server 104, a land transportation branch office server 114, a police agency server 116, and a tablet terminal 118 are connected by a network 100.

  As a configuration, the camera 101 is a camera for photographing a parked vehicle. As a fixed camera, it is attached to a power pole or signal so as to photograph main roads and urban roads. As a moving camera, it is mounted on a police car or taxi, and has a GPS function and location information. Record. These cameras are so-called network cameras, and the captured images are transmitted to a server through the network and stored. The shooting direction and zoom of the camera may be fixed or movable, and in such a case, the shooting direction and zoom are changed automatically or remotely. Further, it may be shared with a security camera as in this embodiment.

  As a process, an image of a road on which a parked vehicle can exist is captured and transmitted to the server as needed. In the case of a transfer camera, the positional information obtained by the GPS function is also transmitted.

  The prefectural police headquarters server 102 is a server managed by the prefectural police headquarters, and has an image received from the camera 101 as image information 103 in the storage device. In this embodiment, the camera is shared with a security camera, and an image taken by the prefectural police for crime prevention is also used for parking control. However, a camera for exclusive use of traffic control or an image server may be used.

  The vehicle monitoring server 104 is a server managed by the prefectural police headquarters traffic department, and controls traffic using the image information of the prefectural police headquarters server 102. The vehicle monitoring server 104 includes a calculation unit 105 and a storage unit 106. The computing unit 105 refers to a vehicle information extraction process 108 that extracts vehicle information from the image information 103, a violation suspect determination process 109 that determines image data relating to a vehicle suspected of a violation, vehicle information 115, and vehicle inspection information 117. A detailed information acquisition process 110 for acquiring detailed vehicle information and a functional unit 107 that operates as a thin client server with the tablet function 118 as a thin client terminal are operating. The tablet function unit 107 has a server-side function for causing the tablet terminal 118 to function as a thin client terminal, and includes a violation information acquisition function 112 for displaying a result referred to from the vehicle information 111 on the tablet terminal 118. In addition, it has a violation registration function 113 for updating the vehicle information 111 by input from the tablet terminal 118.

  The land transportation branch office server 114 has vehicle information 115 which is managed by the land transportation branch office and holds vehicle number information registered in each prefecture in a storage device.

  The National Police Agency server 116 has a storage device for vehicle inspection information 117 which is managed by the Metropolitan Police Department and holds vehicle information registered at the time of vehicle inspection. The vehicle inspection information stores information on vehicles nationwide, and can be used for vehicles of other prefecture numbers.

  The tablet terminal 118 is installed with a program for causing a general touch panel terminal having a display device with a touch panel to function as a thin client terminal, and transmits a user operation input to the vehicle monitoring server 104. The screen data created by the tablet function unit 107 is received and displayed. In addition, it has a GPS positioning function, a function of wirelessly connecting to the printer 119, and a function of transmitting image information captured by the camera to the prefectural police headquarters server.

  The printer 119 is connected to the tablet terminal 118 and has a printing function for printing on paper or a sticker.

  The network 100 can be a wired or wireless Internet line or an intranet line.

  Next, the configuration of data used in this embodiment will be described. FIG. 4A shows camera information, FIG. 4B shows image information, and FIG. 4C shows vehicle information.

  The camera information shown in FIG. 4 (a) is information on cameras installed in the prefecture under the jurisdiction of the prefectural police. Each camera has a unique camera ID, camera type, and camera position. The camera type includes a fixed fixed-point camera and a mobile camera installed in a police car or taxi. The camera position is an installation position for a fixed-point camera, and in the case of a moving camera, it may be blank or the current position, and information on the direction in which the camera is facing may be added thereto.

  The image information shown in FIG. 4B is information on an image photographed by the camera. Holds image file name, shooting position (may include shooting direction and zoom magnification), shooting date and time (in the case of video, may include shooting start time and end time), camera ID Yes.

  The vehicle information shown in FIG. 4C is information about the vehicle obtained from the analysis of image information and related information. Camera ID that shot the image, shooting position, vehicle number, user name, user address, vehicle type, vehicle color, parking stop shooting start time, parking stop shooting end time, driver unloading start time, driver unloading end It has time, parking time, parking flag, image ID, status, remarks, and control status. The shooting position is the position of the camera in the case of a fixed camera, and the position where the vehicle is shot in the case of a moving camera, but may be adjusted in consideration of the distance from the camera to the vehicle and the shooting direction.

  The vehicle number is obtained by analyzing the vehicle number in the image read by the camera. When the vehicle number is hidden during parking, it is read from images before and after parking (when the vehicle has run to the parking position or when it has run away). The user name, user address, vehicle type, and vehicle color store various information acquired from the land transportation branch office server or the National Police Agency server in the detailed information acquisition process.

  In the case of a fixed camera, the parking / stop shooting start time is the time when the parking / stopping operation is detected, and the mobile camera is the time when the parked / stopped vehicle is detected for the first time. The parking / stopping operation is detected by, for example, detecting that the vehicle has stopped at the end of the road (predetermined area) or that the door has been opened by image analysis. In the case of a fixed camera, the parking stop shooting end time is the time when the departure is detected, and the mobile camera is the time when the last parked vehicle is detected. If the moving camera cannot confirm the continuation of parking and stopping, the end time is recorded for the time being, and the end time is updated when the same photographing position is detected for the same vehicle at the subsequent time. The driver departure start time is updated with the shooting date and time when it is determined that there is no person in the driver's seat as a result of image analysis and there is no value in the driver departure start time. The driver leaving time is updated with the shooting date and time when it is determined that there is a person in the driver's seat as a result of image analysis and there is a value in the driver leaving time. The parking / stopping time is the time from the parking / stop shooting start time to the parking / stop shooting end time (current time in the case of continuous parking / stopping), and an end flag is added when the vehicle cannot be detected. If data with the same vehicle number already exists in the data photographed by the fixed camera and the status item is “parking violation (continuation)”, the parking / stopping time is updated by the difference between the shooting date / time and the parking / stopping start time. When data with the same vehicle number and the same position information already exists in the data photographed by the mobile camera, the parking / stopping time is updated by the difference between the shooting date / time and the parking / stopping start time.

  The parking flag is determined based on the parking / stopping time and the driver leaving condition. When there is a parking flag, it can be interpreted as parking, and when there is no parking flag, it can be interpreted as stopping.

  The image is a moving image or a still image taken continuously at a predetermined interval time, and the image ID is composed of a camera ID and time. For example, the image ID taken at 12:34 on January 1, 2015 with the camera IDAAA is assumed to be AAA201501011234. It is also possible to associate a plurality of image data. In addition to the fixed camera image, if additional shooting is performed on the tablet terminal, the image ID is additionally updated.

  The status represents the current status of parking and stopping. When it is detected that a parked vehicle has departed or is not at the parked position, or when there is data of the same vehicle number and different position information, it is updated with “parking violation (end)”. In addition, when there is data having a value in the parking stop time and no value in the parking stop time, it is updated with “parking violation (continuation)”.

  In the remarks, special vehicles such as police vehicles, fire engines, and ambulances are judged automatically or manually, and information is acquired.

  The enforcement status is updated as “Regulated” if the violation registration has been completed, “Not applicable” if the violation registration has been completed, and “Unregulated” if it is being controlled by the tablet terminal.

  The processing based on the flowchart of FIG. 2 is as follows with reference to FIGS.

  Steps 201 to 203 are the flow on the system side, and steps 211 to 216 are the flow on the user side.

  Step 201: The vehicle information extraction unit 108 extracts information from the image and creates vehicle information by vehicle extraction processing.

  An image to be analyzed is acquired from the image information 103 of the prefectural police headquarters server storing the images captured by the cameras, and analysis is performed. First, the vehicle in the image is recognized, and the position and speed of the vehicle are recognized. If the speed is other than 0, the vehicle is traveling and not parked. Also, if the vehicle is near the center of each vehicle traffic lane on the road and there is another vehicle near the intersection stop line or in front, it is considered that the vehicle is stopped due to traffic lights or traffic, so it is excluded from the target. A vehicle that is stationary near the end of the road is recognized as a parked vehicle and added to the vehicle information list.

  In the vehicle information held in the parked parking server shown in FIG. 1, the photographed camera ID and its position are stored. Also, the number of the corresponding vehicle is read from the image and stored.

  In addition, the image capturing time when it is recognized that parking / stopping has started is stored as parking / stopping shooting start time. The time point when it is recognized that parking and stopping has started corresponds to the time when the vehicle arrives at the parking position or the first time that the vehicle is located at the parking position.

  Then, the driver's departure is detected and the time is stored. The vehicle is left when it is confirmed that there is no driver in the driver's seat through the window of the vehicle, or when it is detected that the driver's door is opened and the driver goes out of the vehicle. When there is a driver in the driver's seat, it is assumed that the vehicle is present, and when the driver's location is unknown, it is stored as being present or not detected.

  In addition, when it is detected that the driver gets into the vehicle from the door of the driver's seat after leaving the vehicle, or when it can be confirmed that the driver is in the driver's seat, the time is stored as the end of leaving the vehicle.

  When it is detected that the parked vehicle has started running or there is no vehicle at the parking position, the time is stored as the parking stop time. When it is not possible to detect the end of parking / stopping, it is stored as continuation of parking / stopping.

  In addition, when picking up an image with a moving camera, the same vehicle parked or stopped may be picked up with a different moving camera. In that case, if the vehicle number and parking position are the same, it is assumed that the same parking is continuing. This is the stop time.

  Step 202: Next, a suspected violation determination process for extracting a vehicle to be controlled is performed from the vehicle information.

  First, the parking / stopping time is calculated from the parking / stop shooting start time and the parking / stop shooting end time (current time when parking / stopping continues).

  And it is judged whether it is a control object from parking and stopping time and a driver's leaving state. First, the parking / stopping state of the vehicle is determined in light of the conditions. For example, if the parking / stopping time exceeds 5 minutes or the driver leaves the vehicle, the condition can be set so that the parking is determined. .

  Furthermore, information on the classification of the road on which the vehicle is parked (parking prohibition, parking stop etc.) is acquired from the database. Then, the road classification and the parking / stopping state of the vehicle are compared to determine whether or not there is a violation.

  As a result of the above, information on parking / stopping status, whether the vehicle is in violation, and whether it is continuing is stored in the state of the vehicle status. In addition, information on non-violation and non-enforcement is stored as the enforcement status.

  Step 203: Obtain detailed information about the vehicle determined to be in violation.

  Using the number information, the vehicle information of the land transportation branch office server and the vehicle inspection information of the National Police Agency server are inquired, and information such as the owner, its address, vehicle type and color is acquired and stored. When information is acquired, an input of approval from a parking supervisor or the like may be used as a condition. The storage source of the information to acquire detailed information uses a server (for example, the National Police Agency server) that stores information on vehicles nationwide, and determines the inquiry destination (land transportation branch office of each prefecture, etc.) from the place name of the vehicle number You may do it.

  Some vehicles, such as active ambulances and fire engines, should be excluded from the enforcement of parking and parking violations, but if the information obtained based on the number shows that the vehicle is a relevant vehicle, the remarks column Remember that information and remove it from the crackdown. In addition to the number, it may be determined by image analysis based on the appearance characteristics of the vehicle (display such as shape and “•• Fire Department”), or a parking supervisor may manually determine from the image.

  The vehicle monitoring server 104 repeatedly performs the processes in steps 201 to 203 described above. It is desirable that the processing is performed so that the parking supervisor can be notified within a few minutes at the latest so as not to hinder parking monitoring.

  When there is a parked vehicle near the position information of the tablet terminal and the position information of the vehicle data, this is communicated with the terminal to notify the parking supervisor. Hereinafter, the operation of the parking supervisor when receiving the notification and the processing of the system will be described.

  Step 211: The vehicle information acquired by the violation information acquisition function 112 is displayed on the tablet terminal, and the monitoring person confirms this. The vehicle information includes position information of parked and stopped vehicles, image data, parked and stopped times, and the like, and it can be determined whether or not the vehicle is a control target vehicle. Further, when the vehicle state becomes “parking violation”, the tablet terminal 118 may actively notify the parking supervisor. The image of the vehicle may be displayed for confirmation.

  As a result, if it is determined that the vehicle is to be controlled, it is registered in the “Control status” column of the vehicle information with “Controlled”. The other monitor's tablet terminal can notify the other monitor by displaying this together with the ID of the monitor who is in control.

  Step 212: The monitoring person goes to the site based on the position information and confirms the control target vehicle. At the site, the location of parking and stopping, whether it is a violation area, and the presence or absence of a driver will be confirmed in detail.

  Step 213: As a result of step 212, a violation registration process is started for a vehicle determined to be a control target vehicle. The tablet terminal 108 can display a photographed image together with a photographing time, a vehicle number, and the like. When the driver is in the vehicle, by displaying the image, it is possible to prompt the end of parking and stop, confirm that it is a violation, and confirm the identity of the user.

  Further, evidence can be replenished by performing additional photographing of the vehicle in addition to the photographed image data. An additional shooting button 309 is pressed on the tablet terminal 118 and shooting is performed using the camera function of the tablet terminal 118. The additionally photographed image data is linked to the target vehicle of the vehicle information and stored in the image information 103, and the image ID of the target data of the vehicle information 111 is additionally updated. This image can also be used for calculation of parking / stop shooting end time and the like, similar to shooting by a moving camera.

  Step 214: A mark (sticker) is attached to the offending vehicle. After confirming the violation, the monitor presses the mark print button 310, sends the mark print data from the terminal to the portable wireless connection printer, and prints the mark. In addition to the fixed text, the mark may include the date and time of control, location, and contact information. The printed mark is attached to an easy-to-understand location such as a car window glass or bonnet. After the attachment, the additional photographing button 309 is pressed to photograph an attachment image for evidence. At this time, on the condition that the mark is included in the image to be photographed, the next process may be performed only when the image added by the support system is analyzed and the mark is recognized. After printing the mark, the violation registration button 311 is changed from inactive to active.

  Step 215: When the mark is attached to the violating vehicle, the monitor presses the violation registration button 311 to register the violation. As a result, the violation is registered, and the control status of the target data of the vehicle information 111 is updated with “controlled”. In addition, vehicle information on parking / braking vehicles is transmitted to a server (not shown) that handles traffic violations, and preparations for processing such as payment of penalty and deductions are made later.

  It is also possible to perform mark printing and attachment S214 after performing violation registration S214.

  Step 216: As a result of step 211 or 212, if it is determined that the monitor is not a violation vehicle, the violation exclusion registration button 312 is pressed to perform the violation exclusion registration. At this time, the reason for the exclusion is also input. The control status of the target data of the vehicle information 111 is updated to “not applicable”.

  The screen image of the tablet terminal in a present Example is demonstrated using FIG.

  The tablet terminal 300 is a tablet terminal managed by the transportation department of the prefectural police headquarters. The tablet terminal 300 is connected to the tablet function unit of the abandoned parking server from the Internet line, and functions as a processing terminal for an observer.

  A screen 301 is a screen for confirming a parked vehicle. In the road map 304 displayed on the screen 301, the position 305 of the parked vehicle is displayed. You may display your position and the position of other observers. Vehicle information is output as a table 303. The monitoring person confirms whether there is a control target vehicle around him or her from the vehicle information and the map.

  When the vehicle information 303 and the parked vehicle position 305 on the map 304 are selected and clicked, information on the selected vehicle is displayed as shown on a screen 302. A screen 302 is a screen for confirming information on the designated vehicle, and displays detailed information on the vehicle information on the designated vehicle as shown in Table 306. The monitor switches to this display when searching for a control target vehicle or when going to the site and conducting control.

  In the pull-down 307, the control status of the target data is updated to “cautioned”, “under control” or the like. When a shooting history is associated with the vehicle and shooting No is selected with the button 308, the shot image is displayed. In the shooting history, it is possible to display all parking / stopping history recognized by the system, and to extract conditions such as those that have been violated and those that have been in violation for a long time. With the button 309, additional shooting is performed for the target vehicle at the time of crackdown. The button 310 causes the printer to print a mark for the target vehicle. The button 311 is activated by a print instruction to the printer by the button 310, registers parking / stopping violation, and updates the control status with “controlled”. The button 312 updates the control status of the target data of the parked parking server with “not applicable”.

  It is also possible to display a captured vehicle image. The image is displayed with the shooting time. Past images and current images can be displayed, and can also be displayed with time designation (particularly parking start time and driver leaving time).

  The embodiments of the present invention have been described above. ADVANTAGE OF THE INVENTION According to this invention, a parking monitoring person's business can be supported and parking and stopping vehicles can be monitored efficiently.
