Abstract
A method of and apparatus for measuring any irregularity on a road surface by applying a beam onto a measuring point on the road surface and detecting any change in the vertical position of the center of the beam spot formed on the road surface thereby obtaining data concerning the irregularity on the road surface. The beam spot on the road surface is detected by a unidimensional CCD sensor and the position of the center of the beam spot is determined from the output of the unidimensional CCD sensor. The thus obtained data concerning the position of the center of the spot is suitably processed so that data concerning the irregularity on the road surface is obtained.
