Problems With Imaging Sensor Systems Used For Terminal Homing
Thomas F. Wiener · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1979
A smart sensor is defined as one that measures the appropriate quantities with the required accuracy and extracts the maximum amount of information from those measurements. In that context, an imaging sensor system, consisting of an imaging sensor, a reference image, and an image matcher, is discussed. The interaction of the elements of the system are explored, highlighting technology shortfalls and the problems of realizing the design in hardware are touched on. The basic deficiency in developing an optimum sensor is the lack of an analytical model for the images and the matching process.
