Driver360: A Four-Dimensional Scanning System to Better Understand Drivers

The main objective of this project was to construct a four-dimensional (4D = spatial + temporal) scanning system that can be installed in a driving simulator environment. The novel 4D scanning system, named Driver360, comprises 32 digital single lens reflex (DSLR) cameras and captures time-synchronized highdefinition (HD) videos (≥ 1080p) of a subject sitting in and operating a driving simulator from different angles. In this project, a portable structure that mounts the cameras and can be attached to the existing NADS MiniSim simulator was designed, tested, and manufactured. The structure comprises three moveable stands that are attached to the front, left, and right sides of the NADS MiniSim setup. The cameras mounted on the stands are facing the driver seat from a configuration that we empirically found is suitable. An electronics-controlled triggering system of the Driver360 system was added so the cameras can be triggered all at once.
