A Terminal Text Detection Method Based on Multi-scale Frequency Attention Fusion

中文摘要英文摘要

端子编号检测是变电站二次系统电缆验收中必不可少的一步.为了提升数字校验的精准度与有效性,提出了一个基于多尺度频率注意力融合的端子文本检测方法.该方法运用DBNet作为基本模型,改进其在复杂背景下特征提取不足和融合混叠方面的缺陷.在实际场景下拍摄的端子图会受到现场环境的影响,出现模糊、低分辨率、强背景干扰等问题,导致传统检测算法提取到的目标特征会有很多干扰信息,降低了最终检测效果的准确率.针对以上问题设计了AFT-FFE模块,该模块将自适应傅里叶变换与频率特性增强技术相结合.模型在引入频域后,利用AFT-FFE模块能更好地挖掘出图像中高频成分和结构信息,以减少目标边缘轮廓和其他相关特征信息受到大量干扰的影响.传统的特征融合会在一定程度上出现信息丢失或尺度混乱等问题,提出MSF-KAN模块,通过将非线性关注机制以及动态权重分配策略引入到该模块中,从而该模块能够根据特征层的相关性实现多尺度信息的融合.实验部分,采用私有数据集ZET进行了实验验证,经测试所提出的算法准确率达到91.22%,召回率88.52%,调和平均数达到89.85%,效果比传统算法更好.结果表明该方法在实际场景中能够具备良好的稳健性和实用价值,后续可用于电力系统中发电厂线路检测等其他场景.

The detection of terminal numbers is a very critical task in the acceptance process of substation secondary system cables.A terminal text detection method that incorporates a multi-scale frequency attention mechanism is proposed,which aims to improve the efficiency and accuracy of number checking.DBNet is used as the base model,and improvements are made to address the model's shortcomings in feature extraction and fusion in complex scenes.Terminal images in real-world situations often suffer from blurriness,low resolution,and strong background interference,which poses a challenge to traditional detection algorithms,especially in terms of their limited ability to extract high-quality features.In order to solve this problem,the module AFT-FFE is designed,which combines the adaptive Fourier transform with the frequency feature enhancement technique.This module enables the model to capture the high-frequency details and structural features in the image more effectively by introducing frequency domain analysis,which improves the model's ability to localize the terminal text.In the second aspect,the traditional feature fusion process is prone to the problems of information loss and scale confusion,and the MSF-KAN module is introduced.The module incorporates a nonlinear attention mechanism and a dynamic weighting strategy,which can achieve adaptive fusion and emphasize key information among multi-scale features,and helps to improve the performance stability and detection accuracy of the model in complex backgrounds.For the experimental part,validation is performed on the private dataset ZET.The results show that the proposed method outperforms multiple mainstream algorithms in terms of precision,recall and HMean value,reaching 91.22%,88.52%and 89.85%,respectively.Results verifiy that the method has the good robustness and practical value of the proposed method in practical applications,which is expected to provide strong technical support for scenarios such as wiring inspection of power equipment.
