利用LED和摄像头进行图像传感器通信有望成为水中高效、简便的无线通信方式。在本研究中，我们尝试将R-CNN用于二维LED阵列的识别。R-CNN可以正确识别空气中的二维码和拜耳图案，尽管SURF无法检测到拜耳。尝试用R-CNN识别3种不同排列的水下LED阵列。尽管光在水中衰减，在相机分辨率附近颜色变差，但在16m处仍能识别出拜耳排列的绿色LED。
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.
