This document forms the final report on the development of a stereo vision system that can be mounted inside a rolling tire, known as T2-CAM for Tire-Terrain CAMera. The T2-CAM system measures the three dimensional deformation of the inside of a tire as it rolls over the terrain. The system is designed to work in conjunction with the previously developed Vehicle Dynamics Group VDG wheel force transducer that can measure the forces and moments between a tire and terrain under off-road conditions. The combination of these two systems provide the three dimensional geometry, describing the tire-terrain interface from inside the tire, in combination with all forces and moments acting on the tire. The report describes the experimental results obtained with the T2-CAM System. Results indicate that the system is feasible and can provide valuable data to researchers working in the areas of terramechanics as well as tire modeling and testing. The system meets the initial specifications and is expected to provide much needed new insight in understanding of tire-terrain interaction.
