Measurements in production must be rapid, robust and automated. In this paper a new method is proposed to automatically extract features and parameters of screw threads via Hough transformation from 2D point clouds acquired from profile measuring machines. The described method can be used to automate many operations during screw thread prealignment and drastically reduce operator's influence on the measurement process resulting in lower measurement times and increased repeatability.

Alignment deviation is an important factor affecting measurement accuracy in screw thread measurement. It needs to be detected and controlled to ensure the accuracy of relative thread parameters. The influence on pitch diameter caused by the alignment deviations of workpiece and probe is analyzed in this paper. In order to detect and control the alignment deviation, a vision detection method for the probe tip points is proposed, which integrates the detection of corners and edges and the prediction of motion. Then the X-axial rotation deviation is calculated by tracking the tip points both up and down. The result of tests demonstrates that the detection accuracy of the X-axial rotation deviation is 0.0654° with the background changing during the probe movement. The repeatability of the test procedure is ±0.16%, which proves the detection method is adequately qualified for application.
