BOOKPEDIA BARCODE SCANNER VERIFICATION
However, the more barcode readers that are used, the greater the installation costs and the more significant the required data verification efforts will be, so it is important to select the most suitable method for the packages.įrequently Asked Questions About Barcode Scanners Lastly, six-surface reading involves scanning all sides of the box, including the bottom. Five-surface reading (scan tunnels) involves scanning all surfaces except the bottom. Three-surface reading involves scanning the top and both sides of the box. For example, two-surface reading involves scanning the top and one side of the box. To automate barcode reading, the optimal barcode reader installation must be selected according to where labels are affixed, the number of labels, and the shape of the box. Multiple barcode readers are used when it is difficult to scan boxes with a single barcode reader, such as when there are barcodes affixed to multiple surfaces and when there are different box sizes. It is recommended to choose barcode scanners that can, once the basic setup is completed, automatically adjust camera conditions and image processing such as optimal position correction and binarization without needing the operator to have specialized imaging knowledge. For barcode scanners that use a camera, focusing on codes during operation, the exposure time setting, polarized lighting control, and image correction are all key components for successful reading. A barcode scanner that is easily configured minimizes the time and effort to prepare for the operation.įor this reason, barcode scanners that can adjust to the optimal scanning settings either using buttons on the unit or easy operations from a computer are attracting attention.
BOOKPEDIA BARCODE SCANNER CODE
Barcode scanners and 2D code readers that can instantly find optimal reading conditions can significantly shorten the time taken not only for installation but also for product changeovers on the operating line. Some barcode scanners feature simple, smart settings and operations.
Wireless models with fast, stable scanning performance are effective for improving work efficiency. Handheld barcode scanners are designed to allow operators to hold them in their hands to scan codes. For inline installations, lighting-integrated type barcode scanners that can automatically adjust the image capturing conditions are effective. Codes may not be readable depending on the lighting/camera conditions or settings, as well as glossy surfaces or the marking condition on the target. A code is extracted and decoded to output information. The captured grayscale image is binarized. The image is decoded and output as information.Ī 2D code reader extracts a 2D code from the captured image and decodes it. CCD barcode readers emit light onto the barcode and generate an image from the diffused reflection using the CCD. The narrow and wide bars, as well as the spaces, are detected and decoded. Laser barcode scanners emit a laser beam on an oscillating mirror to scan the barcode. Typical barcode scanners include laser barcode scanners and CCD barcode readers. This is possible thanks to the ultra-wide field of view and deep depth of field of the SR-5000 Series.Ī barcode scanner is a device that reads barcodes. While multiple readers were conventionally necessary for reading one side, simply installing one SR-5000 Series reader per side makes it possible to read the codes on labels affixed on the top and sides of packages of different sizes and varying locations. These readers eliminate the need to prepare to align the packages to one side of the conveyor, thereby contributing to reduced costs and a lower risk of malfunction thanks to the simplified conveyor system.
Stable reading is ensured even when packages of different shapes and sizes are on the same line moving at high speeds, regardless of where the barcode labels are found on the packages. The SR-5000 Series logistics code reader offers an ultra-wide field of view, ultra-long depth of field, and high-speed reading, resulting in easy installation and operation in logistics environments for reliable capture of codes on fast-moving packages.
