A Wear Debris Segmentation Method for Direct Reflection Online Visual Ferrography

Blog Article

Wear debris in lube oil was observed using a direct reflection online visual ferrograph (OLVF) to monitor the machine running condition and judge wear failure online.The existing click here research has mainly concentrated on extraction of wear debris concentration and size according to ferrograms under transmitted light.Reports on the segmentation algorithm of the wear debris ferrograms under reflected light are lacking.

In this paper, a wear debris segmentation algorithm based on edge detection and contour classification is proposed.The optimal segmentation threshold is obtained by an adaptive canny algorithm, and the contour classification filling method koip share price is applied to overcome the problems of excessive brightness or darkness of some wear debris that is often neglected by traditional segmentation algorithms such as the Otsu and Kittler algorithms.
