MEASURING ROTATIONAL POSITION OF LENTICULAR LENS SHEET

A system and method are provided for measuring a rotational position of a lenticular lens sheet (020), which involves a light source (120) emitting light onto at least part of a surface of the lenticular lens sheet, a camera (140) capturing an image of the light reflected (040) by, or transmitted (0...

Zusammenfassung:	A system and method are provided for measuring a rotational position of a lenticular lens sheet (020), which involves a light source (120) emitting light onto at least part of a surface of the lenticular lens sheet, a camera (140) capturing an image of the light reflected (040) by, or transmitted (042) through, the surface, thereby obtaining an image showing a light pattern (060), and a processor (160) determining the rotational position of the lenticular lens sheet relative to a coordinate system associated with the image based on an analysis of the light pattern in the image. Accordingly, the rotational position of the lenticular lens sheet may be determined from an analysis of the captured image of the light emitted from the light source that is reflected or transmitted by the lenticular lens sheet. It is therefore not needed to use specially prepared images nor markers.
