In situations where foundational completion data is lacking and there are few conspicuous points on-site,the detection of deep-buried non-metallic pipelines remains challenging at the current stage.This paper,based on engineering practice,presents a method that a-chieves detection through color difference analysis of images from different historical periods,coupled with ground-penetrating radar.The ap-proach has demonstrated promising results and can provide valuable reference for similar engineering projects.
