This study investigates the mathematical modeling of a multi-head camera system mounted on an unmanned aerial vehicle (UAV) for 3D mapping. Using the FOXTECH 3DM V3 camera system, the research examines camera parameter constraints and evaluates model accuracy through reprojection error and field validation.

This study investigates the skid resistance of recycled asphalt concrete incorporating reclaimed asphalt pavement (RAP) to evaluate pavement surface safety. Three asphalt mixture types were compared using the British Pendulum Tester and Dynamic Friction Tester under simulated long-term pavement surface deterioration.
