ABSTRACT:
Providing a method for correcting a data of irregularity of a surface of a body of rotation with an eccentricity included to a data being not affected by eccentricity. The distance data Lkbetween the tire crown portion10tof the tire10tto be inspected and the distance sensor is measured at each of measurement points Xkat every angular displacement Δθ in a circumferential direction of the tire and also radius value rkare computed from the above distance data Lkand the distance LDbetween the center of rotation of the tire and the distance sensor; and further the surface length Skis computed by integrating the radius value rkwith respect to Δθ from the measurement starting point to a current measurement point k and the irregularity data is converted into the form of (Xk, rk) and then the radius values Rkat the irregularity computing points Xkdividing the one round surface length Skof the tire into equal intervals are computed based on the radius values rkand rk+1 at the measurement points Xkand Xk+1 adjacent to the irregularity computing point Xk, serving as an irregularity data (Xk, Rk) at respective points dividing the surface of the tire crown portion into equal intervals circumferentially the tire.
