Accurately measuring the kinematics of a vehicle is necessary to understand vehicle dynamics. As such, a new technique for measuring planar motion of a vehicle using downward-facing high-speed or high-definition camera is presented in this paper. Forward, lateral, and angular velocities can be obtained simultaneously from a calibrated image sequence by using concepts from digital image correlation (DIC). The technique requires the use of a camera, mounting device (e.g. tripod) and computer for post processing the image sequence. The technique is shown to agree with Radar, GPS, and Accelerometer based techniques for measuring velocity. The camera based system may be well suited to measure lower velocities compared to other common instrumentation systems. Digital image correlation is a technique used to study displacement, deformation, and strain by examining a sequence of digital images of a random pattern on the surface of a material.
