摘要： An automatic digital image capturing and processing system for use in a POS environment, comprising a system housing having vertical housing section provided with an imaging window, and containing an area-type illumination and imaging station for generating and projecting an area-type illumination and imaging zone through the imaging window, and into a 3D imaging volume definable relative to the imaging window. An object motion detection subsystem automatically detects the motion of objects passing through the 3D imaging volume, and generates motion data representative of detected object motion within the 3D imaging volume. And a control subsystem, responsive to the object motion detection subsystem, automatically controls operations within the area-type illumination and imaging station during system operation. The area-type illumination and imaging zone supports automated illumination and imaging of objects passing therethrough, so that digital area-type images of the objects are automatically generated as objects pass through the area-type illumination and imaging zone within the 3D imaging volume during system operation.

摘要： A digital image capturing and processing system comprising a plurality of coplanar illumination and imaging subsystem for producing a plurality of coplanar linear illumination and imaging planes which intersect within a 3D imaging volume defined relative to an imaging window. The system further includes a global object motion detection subsystem for detecting the motion of objects moving through the 3D imaging volume, and a global control subsystem for controlling the state of operations within each coplanar illumination and imaging station during system operation. Each coplanar illumination and imaging subsystem has an object detection state and a code symbol reading state of operation, and includes an array of planar illumination modules (PLIMs) for producing at least one substantially planar illumination beam (PLIB), and a linear image detection array having a field of view (FOV) on the linear image detection array and extending in substantially the same plane as the PLIB, to provide a coplanar illumination and imaging plane (PLIB/FOV) that is projected through the 3D imaging volume, for capturing linear (ID) digital images of an object passing therethrough, for subsequent processing and recognition of information graphically represented in the linear digital images. When the global object motion detection subsystem automatically detects the motion of an object passing through at least a portion of the 3D imaging volume, the global control subsystem manages the state of operation of each coplanar illumination and imaging station, e.g. by driving ore or more of coplanar illumination and imaging subsystems into the code symbol reading state of operation.

摘要： A method for intelligently controlling the illumination and imaging of objects while being moved through a 3D imaging volume. As an object is being moved within the 3D imaging volume of a digital image capturing and processing system projecting a plurality of field of views (FOVs) through the 3D imaging volume, and prior to illumination and imaging. A projected trajectory is determined for the object through the 3D imaging volume. The FOVs which intersect with the projected trajectory of the object, passing through said 3D imaging volume, are determined. Only the determined FOVs are selectively illuminated as the object is moved along its projected trajectory through the FOVs, while digital linear images of the object are formed and detected, for storage and subsequent processing of information graphically represented in the digital linear images.

摘要： A digital image capturing and processing system comprising a plurality of coplanar illumination and imaging stations for producing a plurality of coplanar linear illumination and imaging planes which intersect within a 3D imaging volume defined relative to an imaging window. Each station includes an array of planar illumination modules (PLIMs) for producing at least one substantially planar illumination beam (PLIB), and a linear image detection array having a field of view (FOV) on the linear image detection array and extending in substantially the same plane as the PLIB, to provide a coplanar illumination and imaging plane (PLIB/FOV). The PLIB/FOV is projected through the 3D imaging volume, for capturing linear (1D) digital images of an object passing therethrough, for subsequent processing and recognition of information graphically represented in the linear digital images. Each station also employs a local control subsystem for controlling at least one illumination parameter associated with the production of the PLIB, in response to the motion and velocity of objects detected within the 3D imaging volume during system operation. By virtue of the present invention, it is possible to optimally illuminate objects based on the velocity at which such objects pass through the 3D imaging volume, at point-of-sale (POS) stations and like retail environments. Such illumination control ensures the capture of high quality digital images of objects, resulting in improved image processing.

摘要： A method of illuminating objects using adaptively controlled mixing of spectral illumination energy to form and detect digital images of objects at POS environments with sufficiently high image contrast and quality. The method comprises provides, at a POS environment, a digital image capture and processing system having a system housing with an imaging window, and an area-type illumination and imaging station disposed within said system housing, for projecting a coextensive area-type illumination and imaging field (i.e. zone) through said imaging window into a 3D imaging volume during object illumination and imaging operations. As the object is moved through the 3D imaging volume, its motion is automatically detected, and signals indicative of said detected object motion are generated. In response to the generated signals, a first field of visible illumination is produced from an array of visible LEDs, simultaneously with a second field of invisible illumination from a array of infrared (IR) LEDs. These first and second fields of illumination spatially overlap and intermix with each other and are substantially coextensive with the FOV. During object illumination and imaging operations, the relative power ratio (VIS/IR) of these fields of visible illumination and invisible illumination are controlled as one or more digital images of said illuminated object are formed and detected, captured and buffered, and ultimately processed so as to read one or more 1D and/or 2D code symbols graphically represented in the digital images. During object illumination and imaging operations operation, the relative power ratio (VIS/IR) is adaptively controlled to form and detect digital images of objects at POS environments with sufficiently high image contrast and quality.

In response to the generated signals, a first field of visible illumination is produced from an array of visible LEDs, simultaneously with a second field of invisible illumination from a array of infrared (IR) LEDs. These first and second fields of illumination spatially overlap and intermix with each other to produce a composite wide-area illumination beam that is at least substantially coextensive with the FOV. During object illumination and imaging operations, the relative power ratio (VIS/IR) of these fields of visible illumination and invisible illumination is adaptively controlled as one or more digital images of the illuminated object are formed and detected, captured and buffered, and ultimately processed so as to read one or more 1D and/or 2D code symbols graphically represented in the digital images.
