Abstract

This research focuses on the development of an underwater camera prototype equipped with coral detection capabilities, aimed at supporting marine tourism and conservation efforts. The camera leverages TensorFlow Lite on a Raspberry Pi 4 Model B to execute real-time coral detection using MobileNet SSD V2 and MobileNet SSD V2 FPN Lite models. The system's design addresses the challenges of underwater wireless communication by incorporating a watertight enclosure and mechanical components such as clamps and weights for stability. The prototype was subjected to rigorous testing in freshwater and saltwater environments, demonstrating effective waterproofing and the ability to maintain high-quality image capture and processing. Despite the Raspberry Pi's processing limitations, the coral detection program achieved a frame rate of 3-4 FPS with mean average precision (mAP) ranging from 13.29% to 14.81%. Wireless communication tests indicated a maximum reliable depth of ±70 cm due to significant signal attenuation underwater. The findings highlight the system's potential in enhancing underwater tourism experiences by transforming traditional fishing boats into smart glass-bottom boats and contributing to coral reef conservation through precise and timely monitoring of coral conditions. Future work will focus on improving wireless communication to support greater depths and further enhance the prototype's stability and functionality.
