Abstract

Among growth disorders, 'Short Stature' can be improved through rapid diagnosis and treatment, and for that, it is important to detect early'Short Stature'. It is recommended to measure the height steadily for early detection of 'Short Stature' and checking the kid's growth process, but existing height measurement methods have problems such as time and space limitations, cost occurrence, and difficulty in keeping records. So in this paper, we proposed an 'Development of Kid Height Measurement Application based on Image using computer vision' method using smart phones, a medium that is highly accessible to people. In images taken through a smartphone camera, the kid's height is measured using algorithms from OpenCV, a computer vision library, and the measured heights were printed on the screen through 'a comparison graph with the standard height by gender and age' and 'list by date', made possible to check the kid's growth process. It is expected to measure height anytime, anywhere without time and space limitations and costs through this proposed method, and it is expected to help early detection of 'Short Stature' and other disorder through steady height measurement and confirmation of growth process.

성장 장애 중 저신장증은 빠른 진단과 치료를 통해 호전시킬 수 있는데 이를 위해서는 저신장증의 조기발견이 중요하다. 저신장증 조기발견 및 아이의 성장 과정 확인을 위해 꾸준히 키를 측정하는 것이 권장되지만 기존의 키 측정방법들에는 시간적·공간적 한계와 비용 발생, 기록유지의 어려움 등의 문제들이 존재한다. 그래서 본 논문에서는 사람들의 접근성이 높은 매체인 스마트폰을 이용하는 '컴퓨터 비전을 이용한 이미지 기반 아이 키 측정 애플리케이션 개발' 방법을 제안하였다. 스마트폰의 카메라를 통해 촬영된 이미지에서 컴퓨터 비전 라이브러리인 OpenCV의 알고리즘들을 이용하여 아이의 키를 측정하고, 그렇게 측정된 키는 성별·나이별 표준 신장과의 비교 그래프, 날짜별 리스트를 통해 화면에 출력함으로써 아이의 성장 과정 확인이 가능하도록 하였다. 이 제안된 방법을 통해 시간적·공간적 제약 및 비용 발생 없이 언제 어디서든 키를 측정할 수 있을 것이라 기대되고, 꾸준한 키 측정과 성장 과정 확인을 통한 저신장증 및 성장 장애의 조기발견에 도움이 될 것이라 기대된다.
