Abstract:
1. A multicamera imaging-based bar code reader for imaging a target bar code on a target object, the bar code reader comprising: a housing supporting a plurality of transparent windows and defining an interior region, a target object being presented to the plurality of windows for imaging a target bar code; an imaging system including a plurality of camera assemblies coupled to an image processing system, each camera assembly of the plurality of camera assemblies being positioned within the housing interior position and defining a field of view which is different than a field of view of each other camera assembly of the plurality of camera assemblies, each camera assembly including a sensor array and an imaging lens assembly for focusing the field of view of the camera assembly onto the sensor array; and for each camera assembly of the plurality of camera assemblies, the sensor array being read out at a predetermined frame rate to generate image frames of the field of view of the camera assembly at periodic intervals, the image frames being transmitted to the image processing system, a predetermined frame rate of at least one camera assembly of the plurality of camera assemblies being less than respective predetermined frame rates of others of the plurality of camera assemblies; and wherein the predetermined frame rates are determined based on positions of each camera assembly of the plurality of camera assemblies with respect to the plurality of windows such that those camera assemblies of the plurality of windows determined to be less likely to image a target bar code on a target object presented to the plurality of windows for imaging being assigned a lower predetermined frame rate.
