Title:
【発明の名称】長手方向の光ラインによるレールのうねり及び長い波状起伏の測定
Document Type and Number:
Japanese Patent JP2002500762
Kind Code:
A
Abstract:
A system for measuring unevenness formed by grooves and/or long waves in a surface of an object by using a measuring platform. The system moves the object and the measuring platform relative to each other and projects from the measuring platform a light streak that extends in a direction of the movement onto a surface of the object at a fixed projection angle that is tilted relative to a surface normal of the surface. The light streak is reproduced on a planar, position-sensitive photo receiver with a plurality of successive instantaneous exposures of the photo receiver, where the photo receiver is fixedly arranged on the measuring platform with a recording angle that is tilted relative to the fixed projection angle. The system records the surface along the direction of the movement with a plurality of continuous light-streak images and determines a surface profile of the surface along the direction of the movement from deformations in the plurality of the light-streak images.
