Description

  The present invention relates to a vehicle search system that can be applied to a crime-related vehicle search for the control of a parked vehicle on a road.

  In the control of illegal parking on the road, for example, a police officer marks the tires and ground of illegally parked vehicles and patrols after a predetermined time, and the same vehicle with the above marks does not continue to move from the same place. I have confirmed.

  The method of marking the tire and the ground as a means of confirming that the vehicle is continuously parked requires that the police officer get off the police vehicle or stretch out from the police vehicle.

The problem to be solved by the present invention is to collect data of an immobile vehicle and search for a predetermined immovable vehicle based on the collected data.
A further problem to be solved by the present invention is to search whether the vehicle is a crime-related vehicle.

The vehicle collection system according to claim 1 is:
A digital camera, a vehicle number recognition unit for recognizing a vehicle number of a vehicle photographed by the digital camera, a position measuring means for measuring a current position at the time of imaging of the vehicle, and a current time at the time of imaging of the vehicle And a mobile communication means for sending the vehicle number recognized by the vehicle number recognition unit together with the current position measured by the position measurement means and the current time obtained by the clock means. .

  The vehicle collection system according to claim 2 is characterized in that the position measuring means is a positioning system using a satellite, and the clock means obtains time information from the satellite.

The vehicle search system according to claim 3 is:
A plurality of vehicle collection systems according to any one of claims 1 and 2, comprising a plurality of vehicle collection systems, a data storage unit storing each data sent from each vehicle collection system, and a vehicle number of the data stored in the data storage unit And a vehicle search unit for searching for an immobile vehicle by calculating an immobility time for the same position of the same vehicle number.

The vehicle collection system according to claim 4 is:
A vehicle collection system comprising: a digital camera; a vehicle number recognition unit that recognizes a vehicle number of a vehicle photographed by the digital camera; and a mobile communication unit that transmits the vehicle number recognized by the vehicle number recognition unit. Including any one of the vehicle collection systems according to Item 1 or 2;
The crime related vehicle number is registered in advance and stored for each data sent from the vehicle collection system, and the vehicle number of the data sent to the data storage unit is the crime related vehicle number. A vehicle search unit for searching for a corresponding vehicle is provided.

According to the vehicle search system of the first aspect, since the vehicle is photographed with a digital camera and the vehicle number is recognized by the vehicle number recognition unit, the police officer gets off the police vehicle or stretches his body from the police vehicle. There is no need to work, and labor can be saved.
Also, since illegal parking can be collected without getting off the vehicle, it is possible to expect a decrease in violations due to the caution of not knowing when to check.

  According to the vehicle search system of the second aspect, the position can be measured quickly and the time information of the satellite can be used.

  According to the vehicle search system of the third aspect, since the vehicle number is stored in the data storage unit together with the current position and the current time when the parked vehicle is photographed, the evidence ability can be improved.

  According to the vehicle search system according to the fourth aspect, the crime registration vehicle can be determined for a certain vehicle.

  FIG. 1 is a functional block diagram illustrating a vehicle collection system and a vehicle search system according to the present invention. In FIG. 1, 101 is an illegally parked vehicle, 102 is a digital camera, 103 is a car number recognition unit, 104 is position measuring means, 105 is clock means, 106 is mobile communication means, 107 is fixed communication means, and 108 is data storage. Reference numeral 109 denotes a vehicle search unit. A vehicle collection system 110 includes a digital camera 102, a vehicle number recognition unit 103, a position measurement unit 104, a clock unit 105, and a mobile communication unit 106. The vehicle search system includes a plurality of vehicle collection systems 110, a data storage unit 108, and a vehicle search unit 109.

  The vehicle number recognition unit 103 recognizes the vehicle number of the license plate from the captured image of the vehicle by image recognition technology. The position measuring means 104 is a high-accuracy GPS that is realized by GPS (Global Positioning System) and uses error information from one or more reference stations (not shown) in order to perform position measurement with accuracy in centimeters. As the clock unit 105, for example, a GPS clock unit that constitutes the position measuring unit 104 is used. The time information uses timing generated by the clock means 105 itself or time information from the GPS satellite. The mobile communication means 106 implements data communication. The fixed communication means 107 is provided in the police station data center 111 and receives radio waves from the mobile communication means 106 of the vehicle collection system 110 in a predetermined area. A computer is provided in the police station data center 111, and the data storage unit 108 and the vehicle search unit 109 are configured by a computer.

  A police officer finds the parking violation vehicle 101 and shoots it from a police car, for example, so as to include the license plate by the digital photographer 102. The vehicle number recognition unit 103 extracts a license plate from the photographed image and recognizes the vehicle number. On the other hand, the position measuring means 104 measures the current position every moment, and outputs the current position and the time (including date) at that time to a buffer (not shown) simultaneously with photographing by the digital camera 102, for example. The vehicle number, current position, and time data stored in a buffer (not shown) are output from the mobile communication means 106 after being converted into a predetermined format suitable for transmission together with an identification number given to each police officer, for example. The

  The fixed communication means 107 of the police station data center 111 receives the data signal from each mobile communication means 106, analyzes the vehicle number, the current position, the time and the identification number from the received data for each time. Are stored in the data storage unit 108.

  Each time a record is stored in the data storage unit 108, the vehicle search unit 109 reads the vehicle number and position of the newly stored record, and searches for records in a predetermined range based on the vehicle number and position. If there is nothing parked in the same position with the same car number, the parking time is not calculated as a new illegal parking. The vehicle search unit 109 transmits the fixed communication means 107 with the identification number as “no applicable vehicle”. The police officer having the identification number receives the data “no applicable vehicle” from the mobile communication means 106 and performs predetermined processing. If there is a vehicle parked at the same position with the same vehicle number, the data storage unit 108 records the current time in addition to the previous record, and the vehicle search unit 109 sets the parked vehicle as the oldest parked vehicle. The dead time is calculated from the current time and the current time. When the calculation result is equal to or longer than a predetermined time, the vehicle search unit 109 records it as “immobility time: xx hours XX minutes” and attaches it with the identification number and transmits it from the fixed communication means 107. The police officer having the identification number receives the calculation result from the mobile communication means 106 and performs a predetermined process.

  When a parking violation is discovered by patrol patrol, the data of the police station data center 111 and the data of the currently photographed vehicle are compared to determine whether or not the vehicle is a continuation vehicle. Even if it is not necessary, it is possible to identify a parking violation vehicle only by a shooting operation with a digital camera.

Since the vehicle number recognition unit 103 recognizes the vehicle number of the vehicle photographed by the digital camera 102, a vehicle stolen vehicle or the like is registered and recorded in advance in the data recording unit 108, and the vehicle search unit 109 records the vehicle based on the vehicle number. Automatic search of registered contents can be realized, which can contribute to the early determination of crime registration vehicles. That is, when a vehicle number is sent from the vehicle collection system 110 together with a vehicle inquiry request signal from a police officer, the vehicle search unit 109 sends a vehicle number newly sent by the vehicle inquiry request signal and stored in the data storage unit 108. Is searched for whether it matches the registered vehicle number of the crime-related vehicle. For example, in the case of a stolen car, the identification number of each police officer from a buffer (not shown) is attached together with data necessary for finding the stolen car, and transmitted from the fixed communication means 107. The police officer having the identification number can perform predetermined processing upon receiving information from the mobile communication means 106 that the search result is a stolen vehicle. This crime registration vehicle indexing can be applied not only to parked and stopped vehicles but also to running vehicles.
In the inquiry of the crime-related vehicle, in the vehicle collection system 110, the vehicle communication unit 106 must output the vehicle number by the vehicle number recognition unit 103, the current position by the position measurement unit 104, and the current time by the clock unit 105. Is not necessarily required to use. These position measuring means 104 and clock means 105 can be omitted. When the position measuring unit 104 and the clock unit 105 are used, the current position and the current time together with the vehicle number data are output to the police station data center 111 and recorded in the data storage unit 108 as in the case of the search for the immovable vehicle. . These current position and current time data are used for processing necessary for the investigation, for example.

It is a functional block diagram explaining a vehicle collection system and a vehicle search system.
