Abstract
Official abstract text for this publication.
A method for position calibration of a spot of a known geometry of an optical sensor is disclosed. The method may include providing a position calibration patch on a sheet at a position which is known with respect to a reference position on the sheet, along a scan path of the spot of the optical sensor across the sheet. The patch may include at least two adjacent blocks of different colors. The method may also include obtaining a sampling of the position calibration patch using the optical sensor. The method may further include determining from the sampling a relative coverage of the spot over the color blocks of the position calibration patch, and based on the known geometry of the spot and on the determined relative coverage, determining the position of the spot of the sensor with respect to the reference position.
First claim
