Abstract

In this paper, we implemented an algae removal device that recognizes and removes algae existing in water using Raspberry Pi camera and DO (Dissolved Oxygen) sensor. The Raspberry Pi board recognizes the color of green algae by converting the RGB values obtained from the camera into HSV. Through this, the location of the algae is identified and when the amount of dissolved oxygen's decrease at the location is more than the reference value using the DO sensor, the algae removal device is driven to spray the algae removal solution. Raspberry Pi's camera uses OpenCV, and the motor movement is controlled according to the output value of the DO sensor and the result of the camera's green algae recognition. Algae recognition and spraying of algae removal solution were implemented through Arduino and Raspberry Pi, and the feasibility of the proposed portable algae removal device was verified through experiments.

본 논문에서는 라즈베리파이 카메라와 DO(Dissolved Oxygen)센서를 사용하여 수중에 존재하는 녹조를 인식하고 녹조를 제거하는 기능을 갖는 녹조제거장치를 구현하였다. 라즈베리파이 보드는 카메라로부터 취득한 RGB 값을 HSV로 변환하여 녹조의 색을 인식한다. 이를 통해 녹조의 위치를 파악하고, DO 센서를 활용해 해당 위치의 용존산소량의 감소량이 기준치 이상일 경우 녹조제거장치가 녹조 제거 용액을 살포하도록 구동한다. 라즈베리파이의 카메라는 OpenCV를 활용하였고, 모터의 움직임은 DO 센서의 출력값과 카메라의 녹조인식 결과에 따라 제어한다. 녹조인식 및 녹조제거용액의 살포 기능은 아두이노와 라즈베리파이를 통해 구현되었으며 실험을 통해 제안한 이동식 녹조제거장치의 타당성을 검증하였다.
