摘要： An omni-directional digital image capturing and processing system for use in a POS environment, comprising a system housing having a horizontal housing section and a vertical housing section. The horizontal housing section has a horizontal imaging window, and contains a first plurality of coplanar illumination and imaging stations, for generating and projecting a first group of coplanar illumination and imaging planes through the horizontal imaging window. The vertical housing section has a vertical imaging window, and contains a second plurality of coplanar illumination and imaging stations for generating and projecting second group of coplanar illumination and imaging planes through the vertical imaging window, which intersect and cooperate with the first complex of coplanar illumination and imaging planes within a 3D imaging volume definable relative to the horizontal and vertical imaging windows. This generates a complex of coplanar illumination and imaging planes within the 3D imaging volume, capable of omni-directional imaging of objects passing through the 3D imaging volume. Digital linear images of the object are generated as the object intersects coplanar illumination and imaging planes within the 3D imaging volume during system operation. The system also includes an object motion detection subsystem for automatically detecting the motion of objects passing through the 3D imaging volume, and generating motion data representative of the detected object motion within the 3D imaging volume.

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 (1D) 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： An automatic omni-directional bar code symbol reading system for use in a POS environment. The system comprises a system housing having a horizontal housing section with a first light transmission window, and a vertical housing section with a second light transmission window. A plurality of linear-type bar code symbol reading stations are disposed in the horizontal housing section, for generating and projecting a complex of linear illumination planes through the first light transmission window and into a 3D volume definable relative to the system housing. At least one area-type bar code reading station is disposed in the vertical housing section, for generating and projecting an area illumination beam through the imaging window, and into the 3D volume. The complex of linear illumination planes and the area illumination beam enable the omni-directional reading of bar code symbols on an object passing through the 3D volume, and generation of symbol character data representative of the read bar code symbol. An object detection subsystem automatically detects the object passing through the 3D volume, and generates motion data representative of the detected object motion within the 3D volume. A control subsystem controls operations within the linear-type and area-type bar code symbol reading stations using control data derived from the motion data generated by the object motion detection subsystem.

摘要： A POS-based bar code symbol reading system that reads bar code symbols on objects being passed through the 3D imaging or scanning volume supported by the system, and employs one or more object motion sensors (e.g. imaging based, IR Pulse-Doppler LIDAR-based, ultra-sonic energy based, etc.) to (i) measure or estimate the speed of objects being manually passed through the 3D imaging or scanning volume by the system operator, and (ii) visually and/or audibly display object scanning speed measures or estimates to provide the system operator with feedback for optimizing system throughput. The POS-based bar code symbol reading system has a performance advantage that leads to quicker customer checkout times and productivity gain that cannot be matched by the conventional bar code symbol scanning technology.
