Detecting and Counting Oysters

Abstract

Oysters are an essential species in the Chesapeake Bay living ecosystem. Oysters are filter feeders and considered the vacuum cleaners of the Chesapeake Bay that can considerably improve the Bay's water quality. Many oyster restoration programs have been initiated in the past decades and continued to date. Advancements in robotics and artificial intelligence have opened new opportunities for aquaculture. Drone-like ROVs with high maneuverability are getting more affordable and, if equipped with proper sensory devices, can monitor the oysters. This work presents our efforts for videography of the Chesapeake bay bottom using an ROV, constructing a database of oysters, implementing Mask R-CNN for detecting oysters, and counting their number in a video by tracking them.

A Review of Unmanned System Technologies with Its Application to Aquaculture Farm Monitoring and Management

“…The QGC sends commands to the device and receives the camera and other sensory information on the ground station machine or remote machine; the ROV can be controlled manually or automatically controlled. For manual control of the ROV, control commands are sent to the QGC through a wireless controller [172]. The Argus Mini, an observation class ROV built for inspection and intervention operations in shallow waters and can be used in offshore, inshore, and fish farming industries.…”
