도 1 및 도 2를 참조하면, 본 발명에 따른 골프 거리 및 그린 경사도 측정 장치는 접안렌즈(100), 거리측정 모듈(200), 제1 및 제2 카메라(300, 310), 경사도측정 모듈(400)을 포함하여 구성된다. 1 and 2, the golf distance and green inclination measuring apparatus according to the present invention includes an eyepiece 100, a distance measuring module 200, first and second cameras 300 and 310, and an inclination measuring module ( 400) is included.

상기 접안렌즈(100)는 사용자가 홀 또는 깃대 등의 타겟을 지정하기 위한 뷰 파인더이다. The eyepiece 100 is a viewfinder for a user to designate a target such as a hole or a flagpole.

상기 거리측정 모듈(200)은 레이저 송수신부(210)를 이용하여 타겟의 거리를 측정할 수 있다. 여기서, 레이저를 이용한 거리 측정은 널리 알려진 공지 기술이므로 자세한 설명은 생략하기로 한다.The distance measuring module 200 may measure the distance of the target using the laser transceiver 210 . Here, since distance measurement using a laser is a well-known technique, a detailed description thereof will be omitted.

상기 제1 및 제2 카메라(300, 310)는 스테레오 카메라로 휴대용 본체의 전면에 소정 간격으로 좌우에 배치되며 골프장의 그린 또는 그린 주변에서 이미지를 획득한다. The first and second cameras 300 and 310 are stereo cameras, which are disposed on the left and right at predetermined intervals on the front of the portable body to acquire images on the green or around the green of the golf course.

상기 경사도측정 모듈(400)은 제1 및 제2 카메라(300, 310)로 촬영한 영상을 이용하여 그린 경사도를 측정할 수 있다. The gradient measuring module 400 may measure the green gradient using images captured by the first and second cameras 300 and 310 .

상기 경사도측정 모듈(400)은 연산부(410), 관성센서부(420), CPU(430), 디스플레이부(440), 스피커부(450), 무선통신부(460)를 포함한다.The inclination measuring module 400 includes an operation unit 410 , an inertial sensor unit 420 , a CPU 430 , a display unit 440 , a speaker unit 450 , and a wireless communication unit 460 .

상기 연산부(410)는 제1 및 제2 카메라(300, 310)를 통해 획득한 좌우 이미지에 대해 매칭 연산을 수행하여 골프 그린 깊이 맵(depth map)을 추출한다.The calculator 410 extracts a golf green depth map by performing a matching operation on the left and right images acquired through the first and second cameras 300 and 310 .

상기 CPU(430)는 제1 및 제2 카메라(300, 310) 캘리브레이션 정보를 이용하여 깊이 맵을 3차원 포인트 클라우드(3D point cloud, 이하, 3차원 데이터라 함) 데이터로 변환한다.
