method of centering a character introduced in the identification of a reconnaissance aircraft also character and assembly for implementing the method

摘要

In order to recognize or produce a position of a character in a character recognition apparatus, where the position is centered with respect to the centering direction to effect character recognition, selected points of components of a character to be recognized extending transversely to the centering direction are determined and the determination is used to form centering criteria. This operation is achieved by an evaluation circuit including logic linkage circuits and elements coupling the evaluation circuit to a partial matrix field of a matrix in which the character to be recognized is resolved into raster points and through which the character passes.
