Abstract
Images are captured of linear illumination with improved identification of lines and elimination of noise. A most probable line of multiple lines is identified as the one which is widest, and two parallel lines in proximity are regarded as one if their separation is two or one dark pixels. There is an upper line width limit, to eliminate blooming.
Claims17
An image processor for capturing camera sensor signals and identifying patterns of illumination on a target, wherein the processor identifies a most probable illumination line from a plurality of lines which include spectral reflections from surfaces adjacent to a central line of illumination.
