명세서에서 사용된 용어는 그 단어가 본래 가지는 의미가 확대 해석될 수 있으며 서로 다른 의미를 가지는 단어와 단어가 하나의 단어로 조합됨으로써 광의의 새로운 의미를 가지는 합성어 형태를 취한다. 예를 들어 대화라는 단어와 채널이라는 단어가 합성되어 대화 채널을 이룸으로써 대화가 행해지는 통신 채널을 의미하게 된다. 또한, 명세서에서 제시하는 실시예는 실시에 바람직한 실시예이며, 경우에 따라 다른 구성이 부가되거나 본래 있던 구성이 생략됨이 가능하다. 실시예에서 구성을 포함하다 또는 가지다로 실시될 수 있다.The terms used in the specification take the form of a compound word having a new meaning in a broader sense by combining words and words having different meanings into one word that can be interpreted broadly in the original meaning of the word. For example, the word “conversation” and “channel” are combined to form a communication channel, thereby indicating a communication channel through which a conversation is conducted. In addition, the embodiments presented in the specification are preferred embodiments, and in some cases, other components may be added or the original configuration may be omitted. In an embodiment, it may be implemented to include or have a configuration.

이하, 본 발명에 따른 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 제스처 도어락의 구성을 보인 예시도이다.1 is an exemplary view showing a configuration of a gesture door lock.

제스처 도어락은 도어락을 잠금 또는 해제하는 잠금부(400); 손가락 움직임 이미지를 촬영하는 카메라(100); 및 촬영된 손가락 움직임 이미지와 기준 움직임 이미지를 비교하여 일치하면 잠금부(400)의 잠금을 해제하는 도어락의 제어부(200)를 포함한다.The gesture door lock includes a locking unit 400 for locking or releasing the door lock; A camera 100 for photographing a finger motion image; And a control unit 200 of the door lock that compares the photographed finger motion image with the reference motion image and releases the lock of the lock unit 400 when they match.

제스처 도어락은 손가락 접근을 감지하는 근접 센서를 포함하고, 도어락의 제어부(200)는 근접 센서에 의해 손가락 접근을 감지하면 카메라(100)를 제어하여 손가락 움직임 이미지를 촬영한다.The gesture door lock includes a proximity sensor that detects a finger approach, and the controller 200 of the door lock controls the camera 100 to capture a finger motion image when a finger approach is detected by the proximity sensor.

제스처 도어락은 적외선을 출력하는 적외선 발광부를 포함하고, 제어부(200)는 적외선 발광부를 구동하여 적외선을 출력하고, 반사되는 적외선을 적외선 카메라(100)를 통해 촬영해서 적외선 손가락 움직임 이미지를 획득할 수 있다. 제어부(200)는 적외선 손가락 움직임 이미지에서 픽셀 레벨 클램핑으로 배경을 필터링할 수 있다. 적외선 손가락 움직임 이미지에서 손가락 움직임만 획득해서 이용할 수 있다.The gesture door lock includes an infrared light emitting unit that outputs infrared rays, and the controller 200 drives the infrared light emitting unit to output infrared rays, and photographs the reflected infrared rays through the infrared camera 100 to obtain an infrared finger movement image. . The controller 200 may filter the background from the infrared finger motion image by pixel-level clamping. In the infrared finger movement image, only finger movement can be acquired and used.

제스처 도어락은 입력 모드를 설정하는 스위치(300)를 포함하고, 도어락의 제어부(200)는 입력 모드가 설정되면 사용자 음성을 인식하여 입력 모드에서 저장 모드로 전환하고, 카메라(100)로 촬영된 손가락 움직임 이미지를 정규화하여 기준 움직임 이미지로 저장한다. 스위치(300)는 도어락 실내 측에 구성되고, 사용자가 실내에서 스위치(300)를 조작해서 입력 모드를 설정한 후 카메라(100)에 손가락 움직임을 입력하고, 음성으로 저장을 입력하면 제어부(200)가 기준 움직임 이미지를 저장할 수 있다.The gesture door lock includes a switch 300 for setting an input mode, and the controller 200 of the door lock recognizes a user's voice when the input mode is set to switch from the input mode to the storage mode, and a finger photographed by the camera 100 The motion image is normalized and stored as a reference motion image. The switch 300 is configured inside the door lock, and when a user operates the switch 300 indoors to set the input mode, inputs a finger movement to the camera 100, and inputs a storage by voice, the controller 200 Can store the reference motion image.

도어락의 제어부(200)는 촬영된 손가락 움직임 이미지로부터 정규화 손가락 움직임 이미지를 만들고, 기준 움직임 이미지 또는 정규화 손가락 움직임 이미지에서 9개 픽셀의 사각형 윈도우를 이동하면서 사각형 윈도우의 중앙에서 외측으로 8방향의 윤곽선에 대해 픽셀 연산 누적하여 8방향 특성값을 출력하고, 기준 움직임 이미지와 정규화 손가락 움직임 이미지의 8방향 특성값 간의 수렴 정도에 따라 잠금부(400)의 잠금을 해제한다. 이미지는 카메라(100) 해상도에 따라 달라지며, 이에 정규화 손가락 움직임 이미지가 사용된다. 정규화 손가락 움직임 이미지는 손가락이 일정 크기 내로 수렴되어 있어 8방향 특성값이 일관되게 출력될 수 있다. 일관된 8방향 특성값은 잠금부(400)의 잠금 해제의 신뢰도를 높인다. 사각형 윈도우는 9개의 픽셀로 구성되어 있고, 제어부(200)는 이미지에서 사각형 윈도우를 이동하면서 8방향 특성값을 연산한다. 8방향 특성값은 누적되고 정규화되어 출력된다. 정규화된 두 개의 8방향 특성값이 비교되고 수렴 정도에 따라 잠금이 해제하게 된다.The control unit 200 of the door lock creates a normalized finger movement image from the photographed finger movement image, and moves a rectangular window of 9 pixels from the reference movement image or the normalized finger movement image, while moving the rectangular window in 8 directions from the center of the rectangular window to the outside. The 8-direction characteristic values are output by accumulating pixel operations, and the lock of the locking unit 400 is unlocked according to the degree of convergence between the reference motion image and the 8-direction characteristic values of the normalized finger motion image. The image varies depending on the resolution of the camera 100, and a normalized finger motion image is used for this. In the normalized finger motion image, since the fingers are converged within a certain size, characteristic values in 8 directions can be consistently output. Consistent 8-way characteristic values increase the reliability of unlocking the locking unit 400. The rectangular window is composed of 9 pixels, and the controller 200 calculates a characteristic value in 8 directions while moving the rectangular window in the image. The 8-direction characteristic values are accumulated and normalized and output. Two normalized 8-way feature values are compared and the lock is released according to the degree of convergence.
