Abstract
Image sensor communication using LEDs and cameras is expected as effective and easy wireless communication method in the water. In this research, R-CNN is tried for recognition of 2D LEDs array. The R-CNN could recognize QR code and Bayer pattern in the air correctly, though SURF could not detect Bayer. 3 different arrangement of underwater LED arrays are tried to be recognized by R-CNN. In spite of attenuation of light in the water and color deterioration near camera resolution, green LEDs of Bayer arrangement was recognized at the distance of 16 m.
