Abstract
An original non-contact measurement method using multiple line-structured laser sensors is introduced for seamless steel pipe straightness error is in this paper. An arc appears on the surface of the measured seamless steel pipe against a line-structured laser source. After the image of the arc is accepted by a CCD camera, the coordinates of the center of the pipe cross-section circle containing the arc can be worked out through a certain algorithm. Similarly, multiple line-structured laser sensors are equipped parallel to the pipe. The straightness error of the seamless steel pipe, therefore, can be inferred from the coordinates of multiple cross-section centers obtained from every line-structured laser sernsor.
