Abstract

In this paper, a missed needle rollers inspecting device and a missed needle rollers recognizing algorithm, which are based on mechanical vision technology, are introduced. The cores of this system are image acquisition devices and image processing. The image acquisition system is composed of a CCD, lens, low angle light resource, image acquisition card, and mechanical position. The image processing procedure includes conditioning module, image partition module, image searching module and the number of needle rollers recognizing module. According to the results of dynamic and static testing, a method synthesizing the static and dynamic image acquisition is selected. Meanwhile, the specific parameters of image acquisition and steps of image processing are established. The machine vision technology is used to find the missed needle rollers, the speed of inspecting is promoted, and an automatically, non-touched and online inspecting system is realized.
