  Abstract

An imaging system capable of automatic optical alignment and tracking between terminals in OWC (Optical Wireless Communication) system was developed. Also, to overcome the detection performance limit due to the deterioration in image quality when tracking a OWC terminal located at a long distance (more than 1 km), various image enhancement algorithms were applied and compared with those performances. To this end, a training dataset consisted of target images used for tracking OWC terminal was built and a deep learning model was generated through transfer learning. For a total of 40 images collected through field experiments, the detection performance (mAP) before applying the image enhancement algorithm was 90.0%, but CLAHE (95%), FM (100%), MSR (100%), MSRCR (100%), AMSR (100%), and DehazeNet (92.5%) algorithms were found to improve target detection performance. And considering the target detection performance and processing time, it was analyzed that CLAHE is optimal for coarse tracking of OWC terminals.
