The invention concerns a method for defining the curve of a tubular structure (50), comprising: -determining the inclination of first and second rigid objects (54, 56) fixed in different locations, comprising, for each object: - supplying two accelerometers (A1,...AN) linked to the object and measuring an acceleration in at least one direction of measurement (vj), the respective directions of measurement of the accelerometers being non-colinear; - measuring the terrestrial gravitational field components along said directions of measurement; - solving the matrix equation to determine the inclinationΦof the object (54): -determining the curve of the tubular structure from the inclinations determined for the first and second objects. |
