Abstract

A new method to detect the trace of complex movement of vehicle by using five optical line detectors and fifth-order cross-correlation analysis is proposed. In this method, the curvature and center coordinates of trace segment can be estimated simultaneously together with the velocity of the vehicle's motion. Hence the trace of the vehicle in a fixed measuring time interval can be detected as a circular are and the whole trace is reconstructed as the connection of these arcs. To confirm the usefulness of the proposed method, an actual measurement system has been constructed and experiments using the sham road of which movement was controlled have been carried out. The details of the principle, system construction and the results are shown.
