岩石表面微观纹理的激光测量方法及分形
Measurement of micro-texture of rock using laser and fractal character
摘要
Abstract
A micro-distance measurement system was developed using laser triangulation technique,measuring the surface＇s micro-texture of granite, basalt and other coarse aggregate commonly used on the road, and the system errors such as interference with a variety of factors were analyzed. Using MATLAB platform, analysis the original curve and its data of variety surfaces by Box-counting method, and derived the fractal dimension of surface texture, as a result, for basalt, granite and gravel, and the surface micro-roughness from a complex texture to the simple. A new index of the fractal dimension on pavement aggregate selection was made, and it can be applied to select the stone used on the surface of pavement.关键词
