OPTICAL DETECTION OF OBJECTS HAVING IRREGULAR SURFACES
An object detector reads distance measurement information and determines any presence of at least a portion of an object within a target area between the object detector and a background surface. The determination of the presence is based on distance measurement information. The distance measurement information is compared against a lower distance threshold and an upper distance threshold, where the lower distance threshold represents a distance between the object detector and the background surface, less a subtracted margin; and the upper distance threshold representing a distance between the object detector and a point beyond a distance of the background surface by an added margin. Satisfaction of either distance threshold is indicative of the presence of at least a portion of the object within the target area.

Based on a determination that the image quality parameter of the image of the machine-readable indicia does not satisfy the predefined condition, the voltage being applied to the electrochromic component may be adjusted to cause an opacity level of the electrochromic component to be altered. Otherwise, the voltage being applied to the electrochromic component may remain unchanged.

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 the acquisition phase, a second set of at least one image is captured via at least one of the plurality of image-capture devices according to the set of operational parameters.
