Extraction, Analysis and Creation of Three-Dimensional Road Profiles Using Matlab OpenCRG Tool

[Full Text]



Rakesh Hari Borse





In vehicle systems dynamics, there are wide applications of simulation of vehicles on road surfaces. These simulation applications are related to vehicle handling, ride comfort, and durability. For accurate prediction of results, there is a need for a reliable and efficient road representations. The efficient representation of road surface profiles is to represent them in three-dimensional space. This is made possible by the CRG (Curved Regular Grid) approach. OpenCRG is a completely open source project including a tool suite for the creation, modification, and evaluation of road surfaces. Its objective is to standardized detailed road surface description and it may be used for applications like tire models, vibrations or driving simulation. The Matlab tool suite of OpenCRG provides powerful modification or creation tools and allows to visualize the 3D road data representation. The current research focuses on basic concepts of OpenCRG and its Matlab environment. The extraction of longitudinal two-dimensional road profiles from three-dimensional CRG format is researched. The creation of simple virtual three-dimensional roads has been programmed. A Matlab software tool to extract, create and analyze the three-dimensional road profiles is to be developed.
