  • Automatic generation method for three-dimensional morphology of ruts in asphalt pavements
    Patent number: 12288292
    Abstract: An automatic generation method for three-dimensional morphology of ruts in asphalt pavements comprises: constructing a standard rut cross-section representation model, classifying ruts, acquiring detection data of a rutted section of an asphalt pavement, selecting different rut cross-sections at equal intervals in a longitudinal direction of the pavement, denoising and smoothening the rut cross-sections, selecting feature points according to geometric fluctuation features of the rut cross-sections, connecting the feature points and fitting a cross-sectional curve based on an evolution law of rut deformation, and fusing multiple reconstructed rut cross-sections to realize automatic generation and visualization of three-dimensional morphology of a rut.
