The invention relates to a method for displaying to an operator a rectangular image having a wide field of view of a scene, which comprises the steps of: (a) forming a virtual cylinder from the rectangular image, as if it was first printed on a transparent sheet such that it is visible from both sides of the sheet, and then rolled to form said cylinder; (b) having a perspective view of said cylinder, vertically dividing the cylinder into two halves; (c) vertically shifting one of the cylinder halves until there is no overlap between the two halves; and (d) defining the ellipse which is formed between said two halves following said shifting of step (c) as an orientation plane. |
