Real-Time Multistage IR Image-Based Tracker

摘要

In this paper we describe a real time algorithm for a missile-based IR tracking system. A correlation-based tracker is considered to be the primary tracker, while a feature-based tracker is chosen to provide support on a secondary level. A prescreener runs concurrently with the trackers to provide a list of probable target centroids. This information is used to provide a level of confidence to the tracker. The tracker subfunctions are implemented in both programmable logic hardware and software operating on digital signal processors.
