Image Detection Method and Application of GPR Based on Hough Transform for Pipeline Leakage Defects
Image edge detection is a basic and crucial technology in the field of computer vision.It utili-zes image edge detection technology based on Hough transform method to automatically detect the ampli-tude,relative wave impedance and instantaneous amplitude maps of GPR simulation images of pipeline leakage defects in different directions in this paper.The experimental and actual radar data detection re-sults show that this image processing method can better intelligently identify disease features in GPR ima-ges,play an auxiliary role in artificial detection of GPR pipeline leakage defects,and provide a basic method for machine learning-based disease defect detection.
