AI Technical Summary
Technical Problem
In the prior art, the method of using the acoustic characteristics of underwater acoustic data to identify sand dredging vessels is sensitive to environmental changes, resulting in low recognition accuracy.
Method used
By acquiring image frames of preset waters, the position of candidate ships is detected using a ship detection network, and whether the candidate ship is the target ship is confirmed based on a component detection network, thereby reducing the impact of environmental factors.
Benefits of technology
The accuracy of sand mining vessel identification is improved, the impact of environmental factors on the identification results is reduced, and more accurate target vessel discrimination is achieved.

Abstract
The application discloses a target detection method, device and storage medium. The target detection method comprises the following steps: acquiring a first image frame collected for a preset water area; performing target detection on the first image frame to obtain a target position of a candidate ship in the preset water area, the candidate ship being a ship contained in the first image frame; photographing the preset water area based on the target position to obtain a second image frame containing the candidate ship; and determining whether the candidate ship is a target ship based on a component detection result of the candidate ship in the second image frame. The above scheme can improve the accuracy of target ship detection.
