Abstract
The paper presents a detecting method for oil tube thread, which combines optical techniques and image processing techniques to measure the physical dimension of tube thread and give further analysis. The relevant technqiues such as projection of tube thread, feature of thread image and image processing are discussed, the way for thread image measuring and calibration is introduced in detail. The measurement accuracy is also considered. Finally the application of the measurement is illustrated.
