摘要

利用led和摄像头的图像传感器通信有望成为水中有效且简单的无线通信方式。本研究尝试用R-CNN对二维led阵列进行识别。R-CNN可以正确识别QR码和空中的拜耳图案，SURF无法检测到拜耳。尝试了3种不同的水下LED阵列排列方式来进行R-CNN的识别。尽管在水中光线衰减，在相机分辨率附近颜色变差，但在16 m处仍能识别出Bayer排列的绿色led。

Recognition of 2D LEDs array pattern for underwater image sensor communication by R-CNN

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.
