Method for determining surface structure of moving object by fringe projection system, involves compensating movement of measuring object by time-sequential reading of image areas of image sensor

摘要

The method involves compensating the movement of a measuring object by time-sequential reading of image areas of an image sensor. The illumination of the image sensor takes place by illumination with a certain projected fringe pattern. The compensation of the object movement takes place by a partial image area. The object speed before measurement is detected after fringe light projection process by two temporally successive images.
