SBIR/STTR Award attributes
This STTR Phase II project will develop a multi-sensor system to construct high-resolution depth measurements for smooth surfaces such as concrete and asphalt pavements. The Novateur team will build upon the Phase I prototype system that used COTS components including stereo line-scan camera, a high-resolution color camera, an IMU and artificial illumination. The effectiveness of proposed was demonstrated by generating 3D point cloud estimation of pavement from a moving vehicle and by measuring the height of test objects. The Phase II effort will focus on developing an end-to-end system for stress and deflection estimation of pavement under heavy load, map-enabled visualization of 3D point cloud data and comparison of pavement surface status over time from historic data. The prototype system will be tested at Novateur Team’s Accelerated Pavement Testing Facility (APTF) and at the customer’s site on Heavy Vehicle Simulator (HVS) systems. The proposed effort will build upon the technologies developed during Phase I of this project and will leverage expertise of the Novateur Team in the areas of computer vision, 3D reconstruction, line-scan camera systems, real-time autonomous systems, as well as pavement testing.
