Method for extracting an illuminated zone of a matrix of photodetectors of a light detection device

摘要

The method of extraction of an illuminated area of a light detector photocell matrix of a missile guidance sensor involves dividing a matrix domain (RO) into search zones (r1-R1D) and analyzing theses zones with respect to each other with the aid of a global function to detect the presence of an active light cell (3E-H). If an active dell is detected, the search is restarted with a new area. The stages are repeated to obtain a matrix domain composed entirely of active cells.
