| Abstract: | Based on the contact type measuring machine for bent tube, the probe, which is improved by using laser and CCD, can be used to achieve the non contact measurement of a bent tube. The principle of the non contact measurement of the tube is studied. With the measurement by continuous scanning along the bent tube by moving the probe, a large number of data are obtained. Best fitted line is then used to determine the spatial orientation of the axis of the bent tube, and the measuring accuracy is found to be improved. |
