Three-Dimensional Pavement Crack Detection Algorithm Based on Two-Dimensional Empirical Mode Decomposition

In order to detect pavement cracking with high accuracy, a type of three-dimensional (3D) pavement detection approach is proposed based on a two-dimensional (2D) empirical mode decomposition (EMD) algorithm, a nonparametric and data-driven sifting method which is able to detect pavement cracking without complicated convolution processes. By extending 2D EMD to the analysis of 3D pavement data, the proposed approach first decomposes pavement …
