Abstract

Abstract

The ferro-graphy has great value in the aero-engine operation inspection and the fault diagnosis technology. It is the most important step for the ferro-graphy to get the geometrical sizes of wear debris accurately. But up to now, there isn't a suit of efficient method to get the 3D size of wear debris, especially the thickness. Based on analysis and experiment on stereo vision applied in debris measurement, the whole system, including the hardware, software and arithmetic, was presented to solve the problem of debris measurement primarily. Based on the mechanism of stereo vision apperceiving the depth, optical microscope is applied to simulate the stereo mode to image, and add to the matching method and computing method to processing the image pairs. The system gets the thickness of debris, and the feature of wear debris surface is reconstructed based on the altitude distributing. The method has a better effect, and the results of data or model reach the prospective aim.
