Embodiment Construction

[0014] In the drawings, an exemplary embodiment of the imaging-based barcode reader 10 of the present invention is shown. As in Figure 5 As depicted in the schematic block diagram of the barcode reader 10, the barcode reader 10 includes a circuit 11, the circuit 11 includes an imaging system 12, the imaging system 12 includes a plurality of imaging cameras, and in the exemplary embodiment, there is an original grayscale image Three cameras.

[0015] The image processing system 14 includes one or more processors 15 and a decoder 16, which analyzes the grayscale image from the camera and decodes it if there is an imaged target barcode. The imaging system 12 can image and decode 1D and 2D barcodes and zip codes. The reader 10 can also capture images and signatures. The decoder 16 may be integrated into the reader 10 or may be a separate system, as understood by those skilled in the art. Three cameras are used in the exemplary embodiment, but depending on the design and use of th...

Abstract

A multicamera imaging-based bar code reader (10) for imaging a target bar code (30) on a target object (32) features: a housing (20) supporting a plurality of transparent windows H, V and defining an interior region, an imaging system including a plurality of camera assemblies (C1 - C3) coupled to an image processing system, each camera assembly of the plurality of camera assemblies being positioned within the housing interior. Each camera assembly includes a sensor array. Light reflecting fold mirrors split light from a given camera assembly into portions that are directed out of the housing to different fields of view. Light bounces from a target in a camera field of view back along said light path to the image capture sensor array.

Description

Technical field [0001] The invention relates to an imaging-based barcode reader having a mirror arrangement that defines its field of view. Background technique [0002] Various optoelectronic systems have been developed for reading optical marks such as bar codes. A barcode is a coded pattern including a series of graphic marks of varying widths and spaces, which have different light reflection characteristics. The bar and space patterns encode information. The barcode may be a one-dimensional barcode (for example, UPC barcode) or a two-dimensional barcode (for example, DataMatrix barcode). A system that uses an imaging camera system to read a barcode, that is, to image and decode a barcode, is typically called an imaging-based barcode reader or barcode scanner. [0003] Imaging-based barcode readers can be portable or stationary. A portable bar code reader is a bar code reader suitable for being held by a user and moving relative to a target mark such as a target bar code tha...
