3D Pavement Surface Spherical Representation and Reconstruction

This paper is concerned with the representation of three-dimensional (3D) surfaces, particularly those that are reconstructed using stereo techniques. Pavement surface is chosen as an example for the application of the authors' method for representation and reconstruction of 3D surfaces. Pavement surface texture is one of the important surface characteristics that affect other surface characteristics like splash and spray, and noise. Most stereo methods employ a smoothness constraint to guide the search for correspondences. Unfortunately, the imposition of smoothness causes fine details to be attenuated or removed. For some applications, particularly those involving the analysis of 3D texture, those fine details are important and should be preserved for more accurate assessment of the surface texture. This paper presents a novel surface-representation technique that preserves fine details. The technique is based on fitting a collection of quadratic surfaces (spheres, typically) to a grid of 3D points. The paper assesses the technique in terms of complexity and accuracy.
