Abstract

The existing calculation methods for texture depth of asphalt pavements are easily affected by external and human factors.Therefore，a multi-region plane fitting algorithm for the texture depth based on three-dimensional （3D） linear laser data was proposed.The algorithm preprocessed the collected 3D height data matrix of the pavement and derived a slope-based adaptive filtering algorithm for point cloud data.Then, the 3D height matrix was divided into multiple regions，and the local extremum of the center point was determined.Finally，with the three-point and one-surface plane fitting algorithm as the core，the texture depth of asphalt pavements was calculated.The experimental results show that the correlation between this algorithm and the electric sanding method exceeds 94%，and the complexity is 1/3 of the 3D fitting algorithm.The sample acquisition from point to surface is realized.
