Naturalistic driving studies typically utilize a variety of sensors, including radar, kinematic sensors, and video cameras. While the main objective of such sensors is typically safety focused, with a goal of recording accidents and near accidents for later review, the instrumentation provides a valuable resource for a variety of transportation research. Some applications, however, require additional processing to improve the utility of the data. In this work, we describe a computer vision procedure for calibrating front view cameras for the Second Strategic Highway Research Project. A longitudinal stability study of the estimated parameters across a small sample set of cameras is presented along with a proposed procedure for calibrating a larger number of cameras from the study. A simple use case is presented as one example of the utility of this work. Finally, we discuss plans for calibrating the complete set of approximately 3000 cameras from this study.
