Underground pipeline identification method based on ground penetrating radar image

The invention provides an underground pipeline identification method based on a ground penetrating radar image. The underground pipeline identification method comprises the following steps: step 1, carrying out image preprocessing on obtained ground penetrating radar original image data; step 2, carrying out image segmentation on the preprocessed image; and step 3, carrying out feature identification and extraction on the image after threshold segmentation. According to the underground pipeline identification method based on the ground penetrating radar image, the underground pipeline can be rapidly detected, the identification accuracy is greatly improved, and a large amount of manpower and material resource cost is saved. The judgment result output comprises the number of output diseasesand disease positions, and the diseases are selected and displayed in an original image, so that the diseases are more visual and convenient for a user to identify. 本发明提供了一种基于探地雷达图像的地下管道识别方法，包括以下步骤：步骤1、将得到的探地雷达原始图像数据进行图像预处理；
