基于无人机红外成像的水利工程堤坝渗漏无损检测方法

Non-destructive Testing Method of Dyke Leakage in Water Conservancy Engineering Based on UAV Infrared Imaging

当前,水利工程堤坝渗漏无损检测覆盖范围较小,导致无损检测相位差不断增大。为此,文章提出基于无人机红外成像的水利工程堤坝渗漏无损检测方法。采用多点位的方式,扩大检测的覆盖范围,部署多点位检测节点,进行红外成像无损检测特征提取。设计无人机红外成像堤坝渗漏无损检测模型,利用采用动态平衡处理实现无损检测。结果表明:所用的方法得出的无损检测相位差较小,控制在1.5以下,这说明在红外成像技术的辅助下,文章的方法效果更佳,针对性更强,检测结果真实可靠。

At present,the coverage of on-destructive testing of dyke leakage in water conservancy engineering is small,which leads to the increasing phase difference of non-destructive testing.For this reason,this paper proposes a non-destructive testing method for dyke leakage in water conservancy engineering based on UAV infrared imaging.A multi-point approach is adopted to expand the coverage of testing,and multi-point testing nodes are deployed for infrared imaging non-destructive testing feature extraction.A UAV infrared imaging dyke leakage non-destructive model is designed,and the non-destructive testing is realized by using dynamic equilibrium processing.The results show that the phase difference of non-destructive testing obtained by the method is small,which is controlled below 1.5.It is indicated that with the assistance of infrared imaging technology,the method in this paper is more effective and targeted,and the testing results are real and reliable.
