Application of Weld Scar Recognition in Small-Diameter Transportation Pipeline Positioning System

Application of Weld Scar Recognition in Small-Diameter Transportation Pipeline Positioning System

In order to improve the positioning accuracy of the pipeline inspection gauge (PIG), a pipeline positioning method, based on weld location, is proposed. The position of the welding scar is recognized by wavelet transform modulus maxima (WTMM). Equidistant welding scars provide positioning references...
