Patent ID: 8576278

Claim:
A system for monitoring dynamic stability of a micro machine, comprising: an image-capturing device for capturing images of a micro tool of the micro machine processing on a workpiece; and an analysis device, comprising: an image input interface for receiving the images captured by said image-capturing device; means for transforming the images into gray-level to gray-levelized images; means for analyzing abnormal gray-level ratio of the gray-levelized images, comprising: hues exchanging unit for exchanging dark and bright hues of the gray-levelized images into exchanged gray-levelized images; image-carving unit for capturing bright areas of the exchange gray-levelized images; calculating abnormal gray-level exponential unit for calculating exponential of abnormal gray-level to all pixels of the exchanged ray-levelized images; and calculating abnormal gray-level ratio unit for calculating ratio of abnormal gray-level to pixels of the exchanged gray-levelized images; and means for calculating vein quantity of the gray-levelized images.
