Abstract:
1. A digital image acquisition system characterized by one or more operating parameters, and comprising: at least one digital image formation and detection subsystem having at least a pair of linear imaging arrays, wherein each said linear imaging array is provided with optics for providing a field of view (FOV) on the linear imaging array, so that at least a pair of linear digital images of a target object is formed and detected by said at least a pair of linear imaging arrays during object illumination and imaging operations; an illumination subsystem for illuminating said target object within the FOV of each said linear imaging array during object illumination and imaging operations; an image capturing and buffering subsystem for capturing and buffering at least a pair of composite two-dimensional (2D) digital images of at least one target object during said object illumination and imaging operations; an image processing mechanism for analyzing said at least pair of composite 2-D digital images so to derive velocity data for estimating a relative velocity measure of the target object; and a control subsystem for updating said one or more operating parameters based upon said velocity data, and compensating for changes in said relative velocity measure of the target object as estimated by said image processing mechanism using said velocity data.
