摘要:
A digital image capture and processing system for automatically recognizing objects at a point of sale (POS) station. The system comprising a system housing having an imaging window, and containing a digital image capturing and processing engine including a plurality of coplanar illumination and imaging stations. The stations generate and project a complex of coplanar illumination and imaging planes through the imaging window, and within a 3D imaging volume definable relative to the imaging window for omni-directional imaging of objects passing through the 3D imaging volume, and generate digital linear images of the object as the object intersects coplanar illumination and imaging planes within the 3D imaging volume during system operation. A database is provided for storing one or more object libraries representing objects that can be recognized by the system. A digital image processing subsystem automatically (i) processes digital images generated by said coplanar illumination and imaging stations, (ii) extracts object features from processed digital images, and (iii) recognizes objects which are represented by the object libraries and producing information representative of recognized objects for display at the POS station.
摘要:
A digital image capture and processing system comprising an illumination measurement subsystem for measuring the level of illumination at a particular region of the field of view (FOV) of the system during object illumination and imaging operations, and producing and storing an illumination measure for achieving a desired spatial intensity in a digital image to be formed and detected by the image formation and detection subsystem. An illumination control subsystem uses the illumination measure to control a LED-based illumination array during object illumination and imaging operations. A programmed image processor supports an image-processing based illumination metering program, as well as processes digital images formed and detected by the image formation and detection subsystem so as to read or acquire information graphically represented in the digital images. A computing platform supports the implementation of one or more of the subsystems above, and includes memory for storing at least one code symbol reading application.

A hand-supportable digital-imaging based system for reading bar code symbols involving: automatically detecting the presence of an object within a field of view FOV of the system, and in response thereto, automatically generating an image cropping zone (ICZ) framing pattern and projecting the ICZ framing pattern within the FOV and onto the detected object; visually aligning the code symbol on the detected object, within the ICZ framing pattern; manually actuating a trigger switch when the code symbol on the object is located within the ICZ framing pattern, and while the ICZ framing pattern and a field of illumination are being simultaneously projected onto the object during object illumination operations, forming and capturing a digital image of the code symbol on the detected object; automatically cropping the image pixels contained within the spatial boundaries of the ICZ framing pattern, from the pixels of the digital image; and decode processing the cropped image so as to read one or more 1D and/or 2D code symbols graphically represented therein.

A scanner flipper oscillation frequency analyzing method, computer-readable medium, and apparatus is provided. In one embodiment, the method turns a laser off if the laser is on and receives a signal indicative of a flipper oscillation frequency. The method then compares the signal with stored parameters. Based on the comparison, the method adjusts the flipper oscillation frequency when a percentage variation between the signal and the parameters is above a predetermined value. If the flipper oscillation frequency is adjusted a Digital-to-Analog Conversion value associated with the adjustment is stored in memory. The signal received can be transition signals. In other embodiments, an apparatus and computer-readable medium is also provided which performs the similar features recited by the above method.

An automatically-activated code symbol reading system includes a hand-supportable housing having a light transmission aperture through which a field of view (FOV) passes; and an automatically-activated bar code symbol reading mechanism for repeatedly reading code symbols on an object in the FOV, within a predetermined time period, and in response to each new successful reading of the code symbols, producing a new symbol character data string representative of the read code symbol. A system control subsystem (i) automatically activates the automatically-activated bar code symbol reading mechanism in response to the detection of the object in at least a portion of the FOV, and (ii) automatically activates the data transmission circuit in response to the generation of the data transmission control activation signal so that a symbol character data string, produced currently with or immediately subsequent to the activation of the manually-activatable data transmission switch, is transmitted to a host system.
