A Proposed Optical System for Implementing the Novel Super-Fast Image Processing Scheme - the LPED Method

摘要

LPED method, or Local Polar Edge Detection method, is a novel method the author discovered and implemented in many image processing schemes in the last 3 years with 3 papers published in this and other SPIE national conferences. It uses a special real-time boundary extraction method applied to some binary images taken by an un-cooled IR camera on some high temperature objects embedded in a cold environment background in the far field. The unique boundary shape of each high temperature object can then be used to construct a 36D analog vector (a 36 - "digit" number U, with each "digit" being a positive analog number of any magnitude). This 36D analog vector U then represents the ID code to identify this object possessing this particular boundary shape. Therefore, U may be used for tracking and targeting on this particular object when this object is moving very fast in a 2D space and criss-crossing with other fast moving objects embedded in the same field of view. The current paper will report a preliminary optical bench design of the optical system that will use the above developed soft-ware to construct a real-time, instant-detect, instant track, and automatic targeting high power laser gun system, for shooting down any spontaneously launched enemy surface-to-air-missiles from the near-by battle ground. It uses the total reflection phenomenon in the Wollastron beam combiner and real-time monitor screen auto-targeting and firing system to implement this "instant-detect, instant-kill, SAM killer system".
