Survey of Measurement Method of Taper Thread Plug GaugeLIU Xing-rong, ZHANG Xiao-xi, MA Gui-ru, ZHANG Bo Beijing Institute of Metrology, Beijing 100029, ChinaAbstract:With the development of industry, there are more requirements of accaracy of taper thread plug gauge＇s manufacture. How to im- prove the precision of measuring is an important problem. In this article, we analyze the contact measurement and non-contact measurement for taper thread plug gauge, and the think that using CCD vidicon to detect and measure taper thread plug gauge is a new non-contact measurement method, with the development of machine vision, mode distinguish, image processing and so on, this new method will be used in more fields.[著者文摘]
