도1은 본 발명의 실시예에 따른 안면인식을 통한 관객 만족도 조사 시스템을 설명하기 위한 블록도이다. 도1에 도시된 바와 같이 본 발명의 실시예에 따른 안면인식을 통한 관객 만족도 조사 시스템(20)은 카메라(10), 인터페이스부(21), 영상분석부(22), 표정판정부(23), 저장부(24), 통계분석부(25) 및 디스플레이(26)를 포함한다.1 is a block diagram for explaining an audience satisfaction survey system using face recognition according to an embodiment of the present invention. 1, an audience satisfaction survey system 20 for facial recognition according to an embodiment of the present invention includes a camera 10, an interface unit 21, an image analysis unit 22, a facial expression determination unit 23, A storage unit 24, a statistical analysis unit 25, and a display 26. [

카메라(10)는 공연장이나 전시회장의 출입구에 설치되어, 관람을 마친 관객이 퇴장할 때 안면 이미지를 획득하기 위해 마련된다.The camera 10 is installed at the entrance of a performance hall or an exhibition hall, and is prepared to acquire a facial image when a viewer who has finished the viewing leaves.

인터페이스부(21)는 카메라(10)와 통신 채널을 연결하여, 카메라(10)에서 획득한 안면 이미지를 수신한다.The interface unit 21 connects the camera 10 with a communication channel and receives the facial image acquired by the camera 10. [

영상분석부(22)는 카메라(10)에서 획득한 안면 이미지를 분석하여 특징점을 추출한다. 영상분석부(22)는 도2에 도시된 바와 같이 하나의 촬영 화면에 여러명의 얼굴이 있을 경우, 각각의 얼굴들을 개별적인 얼굴로 인식(다중 얼굴 디텍션)한다. 또한 영상분석부(22)는 도3에 도시된 바와 같이 안면 이미지의 눈 또는 입 모양을 분석하여 특징점을 추출한다.The image analyzing unit 22 analyzes the facial image acquired by the camera 10 and extracts the feature points. As shown in FIG. 2, the image analyzing unit 22 recognizes each face as a separate face (multiple face detection) when there are a plurality of faces on one photographing screen. The image analyzer 22 analyzes the eye or mouth shape of the face image as shown in FIG. 3 to extract feature points.

표정판정부(23)는 영상분석부(22)에서 추출한 특징점을 기 구축된 데이터베이스와 비교하여 스마일 등급을 판정한다. 즉 관객이 웃고 있는지, 울고 있는지, 화내고 있는지 등의 표정을 판정하는 것이며, 더 구체적으로 웃음의 정도를 등급으로 나누어 판정한다. 예컨대 입꼬리가 조금 올라가 있으면 스마일 3점으로 판정하고, 입꼬리가 많이 올라가 있으면 스마일 7점으로 판정하는 것이다.The facial expression determination section 23 compares the minutiae extracted by the image analysis section 22 with the preliminarily constructed database to determine the smile rating. That is, whether the audience is laughing, crying, or being angry. More specifically, the degree of laughter is determined by classifying the degree of laughter. For example, if the mouthpiece is slightly raised, it is determined that the smile is 3 points, and if the mouthpiece is raised a lot, the smile is determined as 7 points.

저장부(24)는 카메라(10)에서 획득한 안면 이미지 및 표정판정부(23)에서 판정한 결과를 저장한다.The storage unit 24 stores the facial images acquired by the camera 10 and the results determined by the facial expression determination unit 23.

통계분석부(25)는 저장부(24)에 저장된 표정판정부(23)의 판정 결과를 통해 만족도에 대한 통계를 산출한다. 예컨대 통계분석부(25)는 표정판정부(23)에서 판정한 스마일 등급의 평균을 내어 별점을 산출할 수 있다.The statistical analysis unit 25 calculates statistics on the satisfaction based on the determination result of the facial expression determination unit 23 stored in the storage unit 24. [ For example, the statistical analyzer 25 can calculate a star rating by averaging the smile ratings determined by the facial expression determiner 23.

디스플레이(26)는 카메라(10)에서 촬영한 영상을 관리자가 확인할 수 있도록 화면 출력한다. 또한 디스플레이(26)는 특징점을 산출하는 영상 분석 과정과, 특징점을 기반으로 산출되는 표정판정부(23)의 판정 결과를 화면 출력한다. 또한 디스플레이(26)는 통계분석부(25)에서 산출한 통계 결과를 화면 출력한다.
The display 26 displays an image taken by the camera 10 so that the administrator can confirm it. The display 26 also displays an image analysis process for calculating feature points and a determination result of the facial expression determination unit 23 based on the feature points. Further, the display 26 displays the statistical results calculated by the statistical analysis unit 25 on the screen.

이상에서 상세히 설명한 바와 같이, 본 발명에 따르면 공연장이나 전시회의 출입구에 카메라(10)를 설치하여 관람을 마친 관객들이 퇴장할 시 안면 이미지를 획득하고, 안면 이미지의 특징점을 분석함으로써 표정을 판독하고, 그 결과를 수치화함으로써 만족도 조사를 수행할 수 있다.As described above in detail, according to the present invention, when a camera 10 is installed at a doorway of a performance hall or an exhibition to obtain a facial image at the time of exiting the viewer, the facial expression is read by analyzing the characteristic points of the facial image, The satisfaction survey can be performed by quantifying the results.

즉, 종래의 설문조사에서는 관객의 참여도가 저조하여 만족도 조사 결과가 객관적이지 못하였으나, 본 발명에서는 수많은 사람들의 표정을 모두 판독하여 결과를 도출할 수 있기 때문에 객관적인 조사 결과를 제공하는 것이 가능하다.That is, although the satisfaction survey result is not objectively based on the audience participation rate in the conventional survey, in the present invention, it is possible to provide an objective survey result because it can read out the results of many people's expressions .

또한, 공연에 대한 여운이 아직 남은 상태에서 자신도 모르게 짓고 있는 표정을 캡쳐하여 조사를 하는 것이기 때문에 조사 결과를 신뢰할 수 있다.
In addition, the result of the survey can be trusted because it captures the facial expressions that the self-unaware facial expressions are still in the remaining state of the performance.
