Abstract
An optical scanner determines ranging to a subject using a localization phase in which a series of image frames is received which collectively contains an aimer spot captured as a reflection off of a surface of the subject. The captured aimer spot is temporally modulated according to a modulation pattern, and the series of image frames is processed to discriminate the aimer spot based on the modulation pattern to determine a probable location of the aimer spot within at least one of the image frames of the series. A triangulation phase follows in which the probable location of the aimer spot is processed to produce the ranging determination. In an optional implementation, an assessment is made whether that probable location of the aimer spot is within a plausible location based on different device-specific positional offsets in image frames captured by different ones of the plurality of image-capture devices.
