Abstract

The present application is applicable to the technical field of visual detection, and provides a method, device, terminal device and storage medium for identifying a water target. The method for identifying a water target includes: acquiring a video stream for a water target; The video frame is input to the first network, and the image of the area where the target object is located in the reference video frame is obtained. The first network is the pruned YOLOv4 network, and the loss function of the YOLOv4 network is Focal Loss; The image of the area where the target object is located and the next frame of the reference video frame in the video stream are input to the second network, and the target in the next frame of the reference video frame is identified through the second network. object. The present application can solve the problem that the existing target identification method is easy to cause missed detection.

Description

technical field [0001] The present application belongs to the technical field of visual detection, and in particular, relates to a method, device, terminal device and storage medium for identifying a water target. Background technique [0002] Traditional ship surface perception technology mainly relies on sensors such as millimeter-wave radar, lidar, inertial measurement unit, and Global Positioning System (GPS) carried on the ship. In recent years, computer vision technology has developed rapidly, and the video stream contains more detailed information of the target object, so the vision-based perception technology is easier to effectively identify the target object on the water surface. [0003] When performing target recognition on a video stream in the prior art, the target recognition of each frame is usually regarded as an independent event, which is likely to cause missed detection. SUMMARY OF THE INVENTION [0004] The embodiments of the present application provi...
