Abstract :
A model of a vision detector is described for the measurement of velocity of a moving object with reduced computing time. The detector is designed utilizing four linear arrays of imaging charge-coupled devices (CCD´s) where the activation of each CCD is controlled by means of a threshold detector (TD) via a computer and external circuits. In comparison to the conventional two-dimensional (area) detector, this model would simplify the complexity of motion detection, and would lead to a significant reduction in required memory length and computation time of a computer. Theoretical analysis demonstrates the model´s capability to uniquely determine the magnitude and direction of the velocity of a moving object for an arbitrary direction of motion.
