Measurement method of tire shape change using CCD (charge coupled device) camera and laser rangefinder

摘要

The present invention detects a measurement point of a measured object two-dimensionally using a CCD camera, then detects a two-dimensional shape by detecting a distance difference of each point after the deformation by a laser range finder, Dimensional position and distance difference measurement values are distributed in three dimensions with respect to each measuring point to detect a three-dimensional deformation amount
