The Pothole Simulation Of3D Digital Road Based On OpenGL

The rapid development of the highway in China, with the opening of the road traffic,the road issues in the course of use become more apparent, So road maintenance technologyhas become a very important task. However, asphalt potholes is one of the most common andtypical pavement disease, which seriously affect the road surface smoothness and drivingcomfort. Once the road surface appeared damaged, if not repaired in time, under the effectsof traffic loads and water，and continue to traffic driving, the extent of damage will soondevelop, resulting in increasing maintenance costs, affecting the performance of the road,and driving serious harm take security personnel.This paper mainly through OpenGL visualization technology, based on thethree-dimensional reconstruction of the road, on the road information data acquisition andprocessing, and thus the size of the computer simulation of the pit, so that the road repair andmaintenance can be easier.The Road surface is a three-dimensional entity, through themapping method to reconstruct the three-dimensional entity in the appropriate highwaymileage, road cross-section and elevation relative to the composition of the three-dimensionalsurface coordinate system, So that you can simply use section of the road reconstruction, andelevation of the profile reconstruction to represent the Three-dimensional reconstruction ofthe road. After three-dimensional reconstruction by thus method,that can reflect the real andthe vast majority of different pavement information.In this paper, based on pavement reconstruction technology, achieve the reconstructionof the real pavement, and simulation of pavement pit size, so that the reconstruction of thereal road, the road out of the pit size simulation is proposed based on three-dimensionaldigital simulation technology of OpenGL pit road. for the three-dimensional pothole roadsimulation conducted a comprehensive, scientific and rational research, and computersimulation analyzes, So efficient pothole detecting of road for the future provides atheoretical basis.Compared with the traditional potholes road simulation technique, this article relates tothe simulation technique is built on the basis of three-dimensional digital systems on the road.Three-dimensional digital reconstruction of the road surface system can not only achieve the real pavement and the path detection of various diseases (including pit road, owned by thepackage, etc.), display quality evaluation information of pavement, but also improve themanagement level of the digital road, So that pothole simulation technique of digitaltechnology has maked digitizing，and with a wide range of applications in the management ofroad maintenance.
