| Abstract: | A micro-distance measurement system was developed using laser triangulation technique,the surface micro-texture of granite,basalt and other coarse aggregates commonly used on the road was measured,and the system errors were analyzed.Using MATLAB platform,the curves and their original data of various surfaces were analysised by box-counting method,and the fractal dimension of surface texture was derived.The overall anti-interference ability of the measurement system is strong and meets the requirements of co... |
