ABSTRACT:
An automated object identification and attribute acquisition system comprising a planar light illumination and imaging subsystem (PLIIM) based linear imaging subsystem, and a laser-based object profiling subsystem integrated within a multi-compartment system housing. The system housing has a substantially unitary construction and includes a first optically-isolated compartment formed in its upper deck portion for containing the PLIIM based linear imaging subsystem and associated components therewithin. The system housing also includes a second optically-isolated compartment formed in its lower deck portion, disposed below the first optically-isolated compartment; for containing the laser-based object profiling subsystem and associated components therewithin. First and second light transmission apertures are formed in the first optically-isolated compartment, for enabling the transmission of a planar laser illumination beam (PLIB) from the PLIIM based linear imaging sybsystem, and towards the object to be illuminated. A third light transmission aperture is formed in the first optically-isolated compartment, and spatially aligned with the first and second light transmission apertures, for enabling the field of view (FOV) of a linear image detection array provided in the PLIIM-based linear imaging subsystem, to project from the linear image detection array towards the illuminated object to be imaged. A fourth light transmission aperture is formed in the second optically-isolated compartment, and spatially distanced from the first optically-isolated compartment, for enabling the transmission of one or more laser scanning beams from the laser-based object profiling subsystem, towards the object being illuminated and imaged. By virtue of the present invention, it is now possible to automatically identify a moving object such as a package moving along a conveyor belt structure, and acquire geometrical and surface attributes thereof, using a single integrated device of substantially unitary construction, thereby simplifying system installation, set-up and maintenance in diverse field of operation
