Three dimensional Road Reconstruction Based on GPS and Ruts

Abstract:

A three dimensional (3D) reconstruction model of road surface was proposed based on global positioning system （GPS） and rut of road cross section. First, non equidistant GPS points were interpolated on Cardinal interpolation algorithm by taking into account different sampling interval of GPS and ruts, then equidistant interpolation points were selected according to requirement. Subsequently, GPS and rut data were fused to construct vertices dot matrix which was used to draw triangle mesh in 3D space. Finally, an experiment system with 3D road model was developed. Practice shows that the method of 3D road surface reconstruction described above is useful to observe rut, pothole and swelling of road.
