This paper presents a project of recording and modelling tunnels, traffic circles and roads from multiple sensors.The aim is the representation and the accurate 3D modelling of a selection of road infrastructures as dense point clouds in order to extract profiles and metrics from it.Indeed, these models sombreros de carin leon will be used for the
The parabolic equation method based on digital elevation model (DEM) is applied on propagation predictions over irregular terrains.Starting from a parabolic approximation to the Helmholtz equation, a wide-angle parabolic equation is deduced under the assumption of forward propagation and the split-step Fourier transform algorithm is used to solve i
