Stereo Line-Scan Camera System for Surface Distress Identification

This SBIR Phase I project will demonstrate the feasibility and effectiveness of a sensor system to capture and construct high-resolution depth measurements for smooth surfaces such as concrete and asphalt pavements. The Novateur team will develop a prototype system using COTS components and test perform tests at its Accelerated Pavement Testing Facility (APTF). The proposed system incorporates hardware components including stereo line-scan camera, a high-resolution color camera, an IMU and artificial illumination. The Phase I effort will include; development of proposed sensor system prototype, algorithms and software tools for efficient stereo line-scan camera to color camera calibration, generation of high-resolution depth surface map and visualization interface. The project will benefit from Novateur Team’s expertise in the areas of computer vision, 3D reconstruction, line-scan camera systems, real-time autonomous systems, as well as pavement testing.
