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 system and method for identifying an object includes a plurality of object sensors, each object sensor configured and arranged to determine at least one parameter describing objects as they are relatively moved with respect to a sensing volume and having a known position and attitude with respect to the sensing volume. A location sensor is configured and arranged to produce position information relating to the relative movement. Outputs from the object and location sensors are passed to a processor and the parameters are associated with respective ones of the objects on the basis of the position information and on the basis of the known positions and attitudes of the sensors. For each object having associated parameters, the processor compares the parameters to known item parameters to assign item identification to the object.

摘要： A planar laser illumination and imaging (PLIIM) based camera system for producing high-resolution 3-D images of moving 3-D objects having arbitrary surface geometry. The PLIIM-based camera system comprises a system housing of unitary construction, a LADAR-based object profiling subsystem, a PLIIM-based linear imaging subsystem, and an image processing subsystem disposed therein. The system housing has first, second, third and fourth light transmission apertures linearly aligned with and optically isolated from each other, and the third light transmission aperture is disposed between the first and second light transmission aperture. The LADAR-based object profiling subsystem projects an amplitude modulated (AM) laser beam through the fourth light transmission aperture, and scans the laser beam across an 3-D object surface of arbitrary surface geometry moving past the fourth light transmission aperture. The return AM laser beam is processed in order to measure the surface profile of the moving 3-D object surface and produce a series of linear 3-D surface profile maps thereof. Each linear 3-D surface profile map comprises a set of 3-D coordinates specifying the location of sampled points along the moving 3-D object surface. The PLIIM-based linear imaging subsystem produces a series of linear high-resolution 2-D images of the moving 3-D object surface. Each linear high-resolution 3-D image comprises a set of pixel intensity values, and each pixel intensity value is assigned a set of two-dimensional coordinates specifying the location of the pixel in the linear high-resolution 2-D image. The image processing subsystem automatically processes the linear 3-D surface profile maps and the high-resolution 2-D linear images captured by the subsystems in order to construct high-resolution 3-D images of the 3-D object surface. By virtue of the present invention, it is now possible to produce high-resolution 3-D images of moving 3-D object surfaces using linear imaging and 3-D profiling techniques.
