Abstract: Thread inspection is an important part within the scope of modern industry inspection for it is the key to guaranteeing the quality of the product. In order to meet the present demand of the market, a kind of intellectualized test method of small pitch of thread parameters is put forward in this paper. Relatively to other detection methods, it can realize non-contact, rapid and accurate measurement of the thread pitch screw parameters. The process of the acquisition of thread image and data processing is also introduced in this paper. And the real-time measurement has been done as well, to prove the feasibility of this method.

Keywords: Non-contact measurement, image collection, image processing, edge detection method
