Abstract

The present invention relates to a monitoring system and method for monitoring illegal fishing, and more specifically, to a monitoring system and method for monitoring illegal fishing characterized by determining whether a vessel is in a fishing or non-fishing state, generating a fishing state image when it is determined to be in a fishing state, outputting the image in real time while simultaneously recording and storing it, and generating a snapshot image and transmitting it to a land server. The present invention exhibits the following effects. First, by using a deep learning-based image analysis algorithm, it is possible to clearly determine whether a vessel is in an operational or non-operational state. Second, since the operation status video is generated, recorded, and saved only when the operation status is determined, the storage capacity of the recorded video can be reduced. Third, by generating snapshot images of the operation status and transmitting them to a land-based server, real-time monitoring functions can be performed on land. Fourth, when the operating state is determined, a wiper is operated to remove foreign matter from the camera lens area, thereby allowing a clear image to be captured. Fifth, when generating images of the operation status, a deep learning-based image analysis algorithm can be used to detect the faces of crew members and mosaic the corresponding areas, thereby preventing infringement of the crew members' privacy.

Description

Monitoring system and method for monitoring illegal fishing The present invention relates to a monitoring system and method for monitoring illegal fishing, and more specifically, to a monitoring system and method for monitoring illegal fishing characterized by determining whether a vessel is in a fishing or non-fishing state, generating a fishing state image when it is determined to be in a fishing state, outputting the image in real time while simultaneously recording and storing it, and generating a snapshot image and transmitting it to a land server. With the entry into force of the UN Convention on the Law of the Sea, almost all coastal states worldwide have recently declared exclusive economic zones, and under international law, fisheries resources within these zones are permitted to be managed by the competent state. Accordingly, each coastal state establishes a Total Allowable Catch (TAC) as a method to efficiently utilize and conserve fishery resources within its jurisdiction. Total Allowable Catch (TAC) is a measure designed to rationally manage fishery resources by setting an annual upper limit on the catch for each species and restricting fishing to within that range. To manage fisheries resources, the Total Allowable Catch (TAC) system is scheduled to be implemented for all fishing vessels by 2028. In addition, the list of price-controlled items will be expanded from the current six species to include species affected by climate change. However, conventional methods for measuring catch volumes require the essential voluntary cooperation of fishermen, and there were problems in accurately calculating the Total Allowable Catch (TAC) due to non-reporting or false reporting that was customarily practiced by fishermen. In order to address these issues, the need for developing a system to identify verifiable fishing processes has recently increased; accordingly, the applicant has researched and developed a monitoring system and method for monitoring illegal fishing.
