본 발명은 주차장 진출입 차량의 차종 및 차량번호 감지장치와 인식률 향상방법에 관한 것으로서, 보다상세하게는 주차장의 진출입로 바닥에 차량의 진입각도 통제를 위한 직진가이드와 진출입로 양측에 초음파 거리센서를 설치하여 주차장 진출입 차량의 차종 및 차량번호 감지장치의 인식률을 가일층 향상시킴으로써 주차장 관리를 자동화하고 무인으로 운영할 수 있도록한 주차장 진출입 차량의 차종 및 차량번호 감지장치와 인식률 향상방법에 관한 것이다.The present invention relates to a vehicle model and a vehicle number detection device and a recognition method for improving the recognition rate of the parking lot entry and exit vehicle, and more specifically, the installation of an ultrasonic distance sensor on both sides of the entry guide and entry path for controlling the entry angle of the vehicle on the entry and exit of the parking lot. By further improving the recognition rate of the vehicle model and the vehicle number detection device of the parking lot entry and exit vehicle, and the vehicle type and vehicle number detection device and recognition rate improvement method for automated parking lot management and unmanned operation.

일반적으로 차폭에 의한 차량종류의 구분은 아래의 표1과 같은바,In general, the classification of vehicle types by vehicle width is shown in Table 1 below.

(표 1)Table 1

종래 주차관리 시스템에서는 주차관리의 자동화 및 무인화 등을 위해 주차장 진출입 차량의 종류와 차량번호를 자동으로 인식하기 위한 센서를 설치하여 운영하고 있는바, 이러한 감지장치는 주차장 진출입로 양쪽면에서 차량까지의 거리를 측정하고 차폭을 계산하여 차종을 구분하게 되고, 또 차량번호는 차량이 특정 지점을 통과할 때 사진을 찍어 영상처리를 통하여 번호판과 차량번호를 인식하고 있다. In the conventional parking management system, a sensor for automatically recognizing the type and number of vehicles entering and leaving the parking lot is installed and operated for the purpose of automating and unmanned parking management. The vehicle number is classified by measuring the distance and calculating the vehicle width, and the vehicle number recognizes the license plate and the vehicle number through image processing by taking a picture when the vehicle passes a specific point.

그러나 상기한 장치는 주차장에 진출입하는 차량이 진출입로와 나란하게 진행하지 않고 비스듬하게 진행할 경우 차폭감지의 오차가 생겨 차종구분의 오류발생 가능성이 높아지며, 또한 번호판이 측면에서 비스듬하게 찍히게 되어 번호인식 오류발생의 가능성도 높아져 주차요금 시비가 빈번하게 발생하는 문제점이 제기되었다. However, in the above device, if the vehicle entering and exiting the parking lot is inclined without proceeding side by side with the entrance and exit, the error of vehicle width detection occurs, and the possibility of error in the classification of the car increases, and the license plate is slanted from the side so that the number recognition error occurs. The possibility of occurrence also increased, raising the problem of frequent parking fee application.

본 발명은 상기한 바의 제반문제점을 해결하기 위하여 주차장의 진출입로 바닥에 진출입 차량의 직진을 유도하는 직진가이드를 설치하여 차량의 진입각도를 임계값 이내로 유도함은 물론 진출입로 양측에 초음파 거리센서를 설치하여 센서에 의한 번호판 인식오류를 획기적으로 줄이는데 그 목적을 둔 것이다. In order to solve the above-mentioned problems, the present invention installs a straight guide that guides the vehicle straight into the entrance and exit of the parking lot to guide the entrance angle of the vehicle within the threshold, as well as the ultrasonic distance sensor on both sides of the entrance and exit. The purpose is to drastically reduce the license plate recognition error by the sensor.

이하, 본 발명의 실시예를 첨부된 도면과 관련하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2 의(A)(B)(C)는 본 발명에 따른 차종 및 차량번호 감지장치의 개략구성을 블럭화 시킨 도면으로서, 본 발명에 따른 주차장 진출입 차량의 차종 및 차량번호 감지장치(1)는 주차장의 진출입로 바닥에 차량의 진입각도 통제를 위한 폭을 갖춘 직진가이드(2)(2a),(2b)와 진출입로 양측에 초음파 거리센서(3)(3a)를 수직으로 설치하여 구성된다.Figure 2 (A) (B) (C) is a block diagram of the schematic configuration of the vehicle model and vehicle number detection apparatus according to the present invention, the vehicle model and vehicle number detection device 1 of the parking lot entrance and exit vehicle according to the present invention Straight guides (2) (2a), (2b) having a width for controlling the entry angle of the vehicle at the entrance and exit of the parking lot and ultrasonic distance sensor (3) (3a) on both sides of the entry and exit is configured vertically.

상기한 바에서 직진가이드(2)(2a)는 양측으로 나누어 설치할 수 있고 그 폭을 넓게하여 중앙으로 하나만 설치할 수도 있으며, 중앙에 하나만 설치된 직진가이드(2b)는 경차에 적용되는 경우이다.In the above bar, the straight guides (2) (2a) can be divided into two sides can be installed to widen the width may be installed only one in the center, only one straight guide (b) is installed in the center is applied to light cars.

한편, 이러한 직진가이드(2)(2a),(2b)는 차량의 직진을 유도함으로써 진입각도가 틀어져 발생하는 차종인식의 오류를 방지할 뿐 아니라 진출입하는 차량의 운전자에게 진행에 부담을 주지 않도록 일정 폭으로 이루어짐이 바람직하다.On the other hand, the straight guides (2) (2a), (2b) not only prevent the error of vehicle model recognition caused by the entry angle is misaligned by inducing the vehicle to go straight, it is a constant so as not to burden the driver of the vehicle entering and leaving It is preferably made of width.

또, 초음파거리센서는 주차장으로 진출입하는 차량의 차폭을 측정하여 차량 의 종류를 자동으로 인식하거나 경우에 따라서는 주차장으로 진출입하는 차량의 번호판을 해독하여 차량번호를 자동으로 인식한다.In addition, the ultrasonic distance sensor automatically recognizes the type of the vehicle by measuring the width of the vehicle entering and leaving the parking lot, or in some cases automatically recognizes the vehicle number by decoding the license plate of the vehicle entering and leaving the parking lot.
