Document Type and Number:
WIPO Patent Application WO/2017/181396
Kind Code:
A1
Abstract:
A method for calculating bending strain of a pipe, the method comprising obtaining a three-dimensional path of a pipe through which a pipe mapper passes; according to the three-dimensional path, obtaining a correspondence relationship between a time vector and each of the coordinate axes in a three-dimensional coordinate system, wherein the three-dimensional path is a curve in the three-dimensional coordinate system; according to a curved surface calculation model and the correspondence relationship, obtaining a bending curvature of the pipe; and according to the bending curvature of the pipe, obtaining the bending strain of the pipe.
