Abstract : The selection and designation of an aimpoint on a known type of target appearing in the field of view of a video tracking system imaging sensor is accomplished by (a) developing binary target patterns from quantized sensor data generated in the video tracking system video preprocessor; (b) measuring the moments of the target patterns; (c) developing and storing a target reference pattern data base; (d) computing from real time binary coding and moment measurement data and from the stored target reference pattern data base an ensemble of estimated aimpoints; (e) testing the validity of the estimated aimpoints; and (f) averaging valid estimated aimpoints to provide an output aimpoint signal. Mechanization of the invention comprehends the use of video tracking system functions to provide quantized binary coded target patterns and the use of dedicated accumulators to generate pattern moment measurements. A microprocessor computes and stores the target pattern reference data base and performs the aimpoint selection algorithm. (Author)
