摘要： Methods of and systems for illuminating objects using planar laser illumination beams having substantially-planar spatial distribution characteristics that extend through the field of view (FOV) of image formation and detection modules employed in such systems. Each planar laser illumination beam is produced from a planar laser illumination beam array (PLIA) comprising an plurality of planar laser illumination modules (PLIMs). Each PLIM comprises a visible laser diode (VLD, a focusing lens, and a cylindrical optical element arranged therewith. The individual planar laser illumination beam components produced from each PLIM are optically combined to produce a composite substantially planar laser illumination beam having substantially uniform power density characteristics over the entire spatial extend thereof and thus the working range of the system. Preferably, each planar laser illumination beam component is focused so that the minimum beam width thereof occurs at a point or plane which is the farthest or maximum object distance at which the system is designed to acquire images, thereby compensating for decreases in the power density of the incident planar laser illumination beam due to the fact that the width of the planar laser illumination beam increases in length for increasing object distances away from the imaging optics. By virtue of the present invention, it is now possible to use both VLDs and high-speed CCD-type image detectors in conveyor, hand-held and hold-under type scanning applications alike, enjoying the advantages and benefits that each such technology has to offer, while avoiding the shortcomings and drawbacks hitherto associated therewith.

摘要： A hand-supportable planar laser illumination and imaging (PLIIM) based camera system for producing digital linear images of a object within a working range, having a substantially uniform white level independent of the velocity of the object. The hand-supportable PLIIM based camera system comprises a PLIIM based imaging system having a linear image detection array with a field of view (FOV), a planar laser illumination array (PLIA) with a plurality of laser diodes arranged in a linear array for producing a planar laser illumination beam (PLIB) coplanar with the FOV, and a micro-controller for controlling the operation of the PLIIM based imaging system. An object velocity measurement subsystem is mounted within its hand-supportable housing, for determining the velocity of the object relative to the hand-supportable housing and generating object velocity data indicative of the determined velocity of the object. During object illumination and imaging operations, the micro-controller uses the object velocity data compute the optical power which each laser diode must produce in order that each digital image of the object, formed by illuminating the object with the computed optical power, will have substantially the same white intensity level independent of the velocity of the object relative to the PLIIM-based imaging system. The computed optical power value(s) are transmitted to the micro-controller, and the micro-controller uses the computed optical power value(s) to drive each laser diode so that it produces a planar laser illumination beam having the computed optical power level with the FOV. By virtue of the present invention, the planar laser illumination beam illuminates the object, and the PLIIM-based imaging system automatically produces a digital image of the moving object, with pixels having a substantially uniform white level, independent of the velocity of the object. Such image characteristics enables simpler and more reliable image processing in applications such as, for example, optical character recognition (OCR) processing, where image pixels having a substantially uniform white level, and a uniform aspect-ratio, are often desired or required.

摘要： A camera-based tunnel-type package identification system comprising at least first and second camera units, a package dimension subsystem, and a data communications network installed about a conveyor belt structure. Each camera unit is mounted about the conveyor belt structure, and has a linear imaging subsystem with a field of view (FOV) having automatic zoom and focus imaging optics, and a camera control computer for controlling the operation of the imaging subsystem. During system operation, package dimension data from transported packages is transmitted over the data communications network to the first and second camera units. Each camera control computer converts received package dimension data to its local coordinate reference system, and generates camera control signals which drive the automatic zoom and focus imaging optics of its associated camera units to enable the capture and processing of linear images of the transported package.

摘要： A method of and system for automatically cropping linear images of a moving object is disclosed. The method comprises automatically capturing a linear range and intensity data map from an object moving with respect to a coordinate reference system. The linear range and intensity data map includes a sequence of data sets taken along a sequence of sample points along the moving object. Each data set includes a set of coordinates specifying the location of the sample point and an intensity value specifying the intensity of light reflected from the moving object at the sample point. The intensity values in the linear range and intensity data map are automatically analyzed so as to determine the coordinates associated with a region of interest (ROI) on the moving object bearing object identifying information (e.g. bar code symbol, textual information, graphics, etc.) A linear image of the object moving within the coordinate reference is automatically captured. The coordinates of the region of interest (ROI) are automatically converted into a set of pixel indices corresponding to the region of interest (ROI) present in the linear image. The set of pixel indices and the linear image are then used to automatically produce a cropped linear image of the moving object. Cropped linear images can be buffered to produce two-dimensional images of the moving object, and then the two-dimensional image can be processed using image-based bar code decoding and/or OCR operators. By virtue of the present invention, it is now possible to crop linear images prior to image processing, on a linear image by linear image basis, thereby substantially reducing the amount of image data that requires image processing. By reducing image data through the cropping operations of the present invention, significant computational savings is achieved.

摘要： A fully automated package identification and measuring system, in which an omni-directional holographic scanning tunnel is used to read bar codes on packages entering the tunnel, while a package dimensioning subsystem is used to capture information about the package prior to entry into the tunnel. Mathematical models are created on a real-time basis for the geometry of the package and the position of the laser scanning beam used to read the bar code symbol thereon. The mathematical models are analyzed to determine if collected and queued package identification data is spatially and/or temporally correlated with package measurement data using vector-based ray-tracing methods, homogeneous transformations, and object-oriented decision logic so as to enable simultaneous tracking of multiple packages being transported through the scanning tunnel.

摘要： A hand-supportable semi-automatic digital imaging-based bar code symbol reading system comprises: an automatic object presence detection subsystem; a multi-mode image formation and detection subsystem having narrow-area and wide area image capture modes of operation; a multi-mode LED-based illumination subsystem having narrow-area and wide area illumination modes of operation; an automatic light exposure measurement and illumination control subsystem; an image capturing and buffering subsystem; a multi-mode image-processing bar code symbol reading subsystem; an input/output subsystem; a manually-actuatable trigger switch; and a system control subsystem for controlling the subsystems. The digital imaging-based bar code reading system employs a three-tier modular software architecture for carrying out its image-processing based bar code symbol reading operations. The three-tier software architecture comprises an application layer, a system core layer, and an operating system (OS) layer.
