[0034] The invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] Step (1): input image size is 640 × 640; a first-order target detection network lightweight YOLOv5s;
[0036] Step (2): The SSA spatial sharpening module and SE, ECA channel attention module combination, and attention divided into two modules: the channel and mixing attention module attention module, such as figure 2The channel attention is shown; all of the large residual blocks of the skeleton network of a stage of lightweight neural networks and the class FPN structure; channel attention modules are connected in series SSA space sharpening modules and embedded to a stable lightweight The node of the neural network output section, if the neural network includes the lower sampling structure, the next sampling node is embedded, here is a shallow feature 1 Take an example, set i 1 For the input characteristics of the hybrid focus module, the ...
