Embodiment Construction
[0050] Such as Figure 1 to Figure 4 As shown, the present invention provides a method for information extraction and identification by identifying dot matrix patterns, comprising the following steps:
[0051] S10. The infrared reading device emits infrared light to read the dot pattern, and when the infrared light reaches the surface of the dot pattern, an image of the dot pattern is obtained and the image is fed back.
[0052] S20. Use the infrared reading device to perform automatic exposure processing on the fed-back image, so that the gray level of the image reaches a preset range, and put it into the cache.
[0053] Wherein, step S20 includes:
[0054] Filter out unnecessary spectra through filters;
[0055] Capture the remaining spectrum through the optical lens;
[0056] Adjust the exposure time of the lens and the graphics frame rate, so that the gray level of the captured image of the complete graphics frame reaches between 110 and 200.
[0057] S30. Perform pars...
