Problems solved by technology

However, when using neural networks for image detection, the biggest problem is the lack of data sets, and the second is that in the face of low-quality pictures, if the network learning ability is not enough, the target cannot be detected, and false detections and missed detections are more likely to occur.

Embodiment

[0039] Example: such as figure 1 As shown, a marine ship detection method based on the improved YOLOV3 algorithm includes the following steps:

[0040] Step 1. Design a multi-scale feature fusion network structure: The multi-scale feature fusion network structure is to add a detection scale to the original YOLOV3 network structure; Darknet-53 is used as the feature extraction network of the entire model.

[0041] The original network has three detection scales, so four functional layers are added at the end of the original network to achieve the preliminary fusion of the fourth detection scale.

[0042] The network structure of the newly added scale is as follows:

[0043] The first layer is the link layer, which links the output features of the third scale of the original network as the input of the initial scale fusion operation; the second layer is the convolution layer, and the size of the convolution kernel is half of the previous layer, and the size is 1* 1 / 1; the thir...

Description

technical field [0001] The invention belongs to the field of computer vision target detection, in particular to a marine ship detection method based on the improved YOLOV3 algorithm, which can be used for marine ship target detection. Background technique [0002] Aiming at the problem of ship detection and recognition under the ocean background, there are currently two common solutions. One is the imaging series, which is mainly based on the detection methods of SAR images and infrared images based on aperture synthetic radar. Its application is relatively mature, but its Imaging fails to contain rich spectral information of the target, and deviates from human visual habits, which is not conducive to the network to extract richer feature information, thereby reducing the accuracy of detection. Another type of non-imaging series uses sonar and other technologies to obtain relevant signals of ship targets, but the maritime environment is complex, and the communication transmi...
