Abstract

This paper discussed the sytsem of a photoelectric auto- measuring which is used to measurng size of the internal diameter. In this system incldue the charge coupoled devices CCD measuring unit, signal procesing unit and micro-computer controllign unit, to realize non-contact measurement. Ppaer gives structure and principle of the system, specially gives the method of increasing stability of system.
