Mobile system for road inspection and 3D modelling. Introducing new technology within the project "Digital roads New Zealand"

Regular inspections and the maintenance of roads support traffic safety. Inspection technologies may benefit from latest developments in sensor systems, camera technology and computer vision. The paper discusses the application of novel mobile technologies, including stereo vision and visual odometry, for modelling and analyzing extensive segments of roads. Applications of the developed system have been evaluated at test sites in New Zealand within an international collaboration project entitled "Digital Roads New Zealand". By this IPS measurement campaign, a combination of real time trajectory estimation and 3D environment modelling was demonstrated; results are accurate and reliable over long time periods or trajectory lengths, with real time 30 point cloud generation (at 10 fps). This is a promising technological basis for various applications. The presented cost­ effective approach for data acquisition enables a high repetition rate. It is therefore not only well-suited for road inspection but also for change detection since time series of point clouds are exactly temporally and spatially referenced. (A)
