Study On Image Analysis System Of Polymeric Microscopic Structure

Material properties are relied on material micro-structures. By observing and analyzing character, size and distribution of microscopic structure of material, it's ingredient and performance can be known to us. In recent years, people still analyze and appraise polymeric material structure using traditional qualitative and half-quantitative methods with lower automatization degree, people have gathered much experience when they research on metal material structures, however. Doing these measurements only on handwork is not practical due to it's inaccurate calculating results and heavy work.With the development of computer technology, the applications of image processing being used in analyzing and detecting become more and more, how to make better use of image processing in quantitative analysis is a project worthy to be researched. The application of the image processing's and quantitative metallography's fundamentals and methods being used in polymeric material structure's image analysis system is mainly discussed in this paper . The common operations and arithmetics about image processing are introduced in this paper, and the application of mathematical morphology being used in structure analysis is mainly discussed. Besides, based on the fundamental of quantitative metallography, several common characteristic parameters' measurements and tokens are discussed. Then, the analysis system is scaled, and the system's error is discussed too.In this research, an quantificationally analyzing system of microscopic structure based on MATLAB was developed with the application of computer image processing technology, which own visual interface and human-computer interacting function. Taking the measurement of CB rubber micro-structure's geometric parameters as example, how to use the system and the common flow were introduced, some characteristic parameters were measured automatically. The conclusion proves that the image analysis system with accurate calculating and convenient operation, can compensate for the measurement on handwork well.
