摘要
针对输电线路外力破坏的随机性与高危害性,提出基于多尺度序列视觉特征融合模型的输电线路防外破红外感应预警技术。利用主站、基站和红外摄像机等设备组成红外感应系统,采集输电线路图像;利用大气散射模型增强图像对比度,提高图像质量;采用高斯金字塔模型,分别提取图像中不同尺度序列的颜色和亮度特征;引入注意力机制计算显著度最大值,结合目标面积大小融合不同尺度特征,并做线性变换,检测识别目标是否存在外力破坏点,如果存在安全隐患,则触发预警系统。实验结果表明,所提方法不仅提高红外图像质量,还能减少错误预警事件,有利于提高输电线安全。
Targeting at the randomness and high risk of transmission line external damage,an infrared induction early warning technology for transmission line external damage prevention based on multi-scale sequence visual feature fusion model is proposed.The main sta-tion,base station,infrared camera and other equipments are used to form an infrared induction system to collect the image of the trans-mission line.Atmospheric scattering model is used to enhance image contrast and improve image quality.Gaussian pyramid model is used to extract the color and brightness features of different scale sequences in the image.The attention mechanism is introduced to cal-culate the maximum value of saliency.Different scale features are fused according to the size of the target area,and linear transformation is made to detect and identify whether the target has external force damage points.If there are safety hazards,the early warning system will be triggered.The experimental results show that the proposed method not only improves the quality of infrared image,but also re-duces the error warning events,which is conducive to improving the safety of transmission lines.
