By vantal The resolution of bar code scanner should be determined from three aspects: optical part, hardware part and software part. In other words, the resolution of the barcode scanner is equal to the resolution of its optical components plus the resolution obtained through hardware and software processing and analysis.In addition to these aspects, Custom USB Reader The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://www.edoo-iot.com/
Optical resolution refers to the actual number of light spots that can be captured by the optical components of a bar code scanner per square inch. Refers to the physical resolution of barcode scanner’s CCD (or other photoelectric devices) and the real resolution of barcode scanner. Its value is obtained by dividing the pixels that can be captured by photoelectric elements by the maximum horizontal scanning size of bar code scanner. After computer software and hardware processing, the output image will become more realistic and the resolution will be higher. At present, most bar code scanners sold in the market have the function of extending the resolution of software and hardware. When scanning an image, the higher the set scan resolution, the better the generated image effect, the larger the generated image file, but the more interpolation components.
Nowadays, two-dimensional bar codes are widely used. As long as enough user groups are cultivated and combined with a good business model, two-dimensional bar code will become one of the most powerful tools to communicate reality and virtual reality.
