Automated boresight correction optical tracking

A new algorithm has been developed to increase the speed, reliability, and flexibility of the automatic programmable film reader (APFR). The major steps in this new algorithm, known as the N-algorithm, are prediction of target position, establishment of target and plume filters, and location of target. Unlike previous automatic tracking attempts, the N-algorithm is provided with several different methods for tracking targets; it selects the fastest and most reliable method capable of tracking the target. More tracking methods will be required in the future, and the algorithm needs more ability to adapt to a given target image.
