Paper Abstract

A vision system that estimates the trajectory (velocity and direction) of moving targets in a 2D field at video frame rates has been developed and constructed. The system uses an optical Fourier processor to calculate the frequency domain representation of moving objects from which their trajectory is estimated using conventional electronic processing techniques. In a series of experiments, target velocities were estimated to within 4 percent of their actual value and direction was estimated to within 3 degrees.
