Provided is a parking service providing method using vehicle identification based on image grouping. The parking service providing method includes the following steps of: collecting vehicle images from CCTV cameras photographing a vehicle in a direction orthogonal to a parking direction of the vehicle, installed to be opposed to an entering direction of the vehicle, and installed at both ends of each parking zone so as to photograph the inside of each parking zone; extracting a vehicle number plate from a vehicle which is a subject of at least one frame included in the collected vehicle images, and then, tracking a trace of XY-axis coordinates of each corner of the extracted vehicle number plate; searching for a moment when the trace of the XY-axis coordinates is transformed from a linear trace into a nonlinear trace, and then, grouping at least one frame before the moment when the trace is transformed into the nonlinear trace, as an image about one single vehicle; and mapping at least one text of a vehicle number plate recognized from the grouped at least one frame with a vehicle number of the single vehicle to store the text. Therefore, the present invention is capable of eliminating an error with which a parking lot appears to be full even when there are empty parking zones.

    이미지 그룹핑 기반 차량 식별을 이용한 주차 서비스 제공 방법이 제공되며, 차량의 주차방향과 직교방향을 촬영하며, 차량의 진입방향과 대향되도록 설치되며, 각 주차구역의 내측을 촬영하도록 각 주차구역의 양단에 설치된 CCTV 카메라로부터 차량영상을 수집하는 단계, 수집된 차량영상에 포함된 적어도 하나의 프레임의 피사체인 차량으로부터 차량번호판을 추출하고, 추출된 차량번호판의 각 모서리의 XY축 좌표의 궤적을 트래킹하는 단계, XY축 좌표의 궤적이 선형궤적에서 비선형궤적으로 변경되는 시점을 검색하고, 비선형궤적으로 변경되는 시점 이전의 적어도 하나의 프레임을 하나의 차량에 대한 이미지로 그룹핑하는 단계, 및 그룹핑된 적어도 하나의 프레임에서 인식된 차량번호판의 적어도 하나의 텍스트를 하나의 차량의 차량번호로 매핑하여 저장하는 단계를 포함한다.
