QR code recognition on red materials

2024-04-30 10:10:41

When it comes to the New Year, the representative color that naturally comes to mind is “red”

From clothes to streets and alleys, beautiful New Year red is spreading everywhere

It can be said that among the must-have items for the Spring Festival

You can definitely see the popular products

These products inevitably have to go through the code reading process during production.

So do you know the key points for selecting a code reader in this scenario?

Let’s share it in this issue

QR code identification on red materials~

 

  01 Dot matrix code on red metal

 

Analysis of key points for selection:

Dot matrix code, the size is only 5-8mm, the continuity difference is large

Metal background, strong reflection

Red background, ordinary red light code reader cannot recognize

There is a certain concave and convex curvature

 

Selection recommendations

RCD-AI100-XQ-06WD

 

white light source

 

Choose RCD-AI100-X series code readers with optional white light sources to obtain clearer QR code images. It supports code reading with different background colors and has strong scene compatibility.

 

polarizer

 

Through angle adjustment and the filtering effect of the polarizer, most of the background stray light can be filtered out, resulting in a clearer image.

high resolution

 

Resolution 1280*800, can stably identify ultra-small codes (one-dimensional barcode minimum 0.03mm; two-dimensional barcode minimum 0.02mm)

 

Excellent decoding algorithm

 

Advanced sampling technology can normally obtain high-precision materials in noisy scenes and smoothly read DPM codes with severe distortion.

 

Different from the single-core/2-core processors used in the same type, the 4-core SMP processor can effectively cope with harsh code reading conditions. Taking full advantage of multi-threading, the speed is increased by 6 times compared with the performance of single-core code readers; it improves the usage efficiency of CPU, FPU and external hardware devices, shortens the system response time by 30%, and achieves millisecond-level rapid positioning and decoding.

Selection recommendations

RCD-AI100-SQ-06WD

 

white light source

Use the RCD-AI100-S series code reader with optional white light source to obtain clearer QR code images.

 

One-click intelligent parameter adjustment

Just press the "Tune" button on the code reader body to automatically adjust the focus, exposure, gain and code search parameters for different scenes such as dark field and bright field.

Liquid focus technology

 

Using advanced liquid focus technology, it can achieve a single millisecond-level zoom speed and only need a few sample pictures to achieve precise focus. Compared with traditional mechanical lens focus technology, which requires hundreds of samples to complete focus, the sampling speed reaches nearly a hundred times. The improvement has the advantages of fast, accurate and clear focusing.

 

Supports reading multiple code systems

 

Through angle adjustment and the filtering effect of the polarizer, most of the background stray light can be filtered out, resulting in a clearer image.

It has a rich line of smart code reading products and recommends targeted selection solutions based on actual application scenarios. The reading rate and accuracy are higher, which continuously improves the user experience of using smart code readers in various scenarios.
