Simple and rapid composite two-dimensional code recognition system

Abstract

The invention discloses a simple and rapid composite two-dimensional code recognition system, which comprises a recognition method and recognition equipment, and is characterized in that the recognition method comprises the following steps: S1, two-dimensional code composite design; s2, capturing two-dimensional code feature information; s3, calculating a view area where the two-dimensional code is located; s4, capturing two-dimensional code information of different colors; s5, recognizing the two-dimensional code information layer by layer according to a preset category, and finally obtaining effective information; s6, ending the process; the identification device comprises a camera support, a rotating shaft, a filter lens clamp and a filter lens, and a rotating motor is installed in the camera support. According to the method, the two-dimensional code information is classified through colors, so that the information storage capability and the information classifiable capability are greatly improved. When the two-dimensional code needs to bear a large amount of information, the calculation amount of the two-dimensional code can be greatly optimized, so that a computer with low cost and low calculation capability can also meet the requirement of calculation.

Description

technical field [0001] The invention relates to the related technical field of two-dimensional code recognition equipment, in particular to a simple and fast composite two-dimensional code recognition system. Background technique [0002] With the development of new technologies such as robots and artificial intelligence, more and more unmanned factories have appeared in traditional manufacturing enterprises. Robots, vision technology, and unmanned vans are used in many scenarios in these unmanned factories, such as sorting scenarios in warehousing logistics and factory material handling scenarios. Two-dimensional code recognition technology is the underlying support technology of the above-mentioned new technologies, such as unmanned handling vehicles that navigate through two-dimensional codes, and sorting systems that use two-dimensional codes for information identification. [0003] Some manufacturers reduce the demand for computing performance of the QR code recognitio...

Problems solved by technology

Regardless of whether the camera or the fill light is an electric drive device, it will heat up due to the thermal effect of the current during the work process, causing most of the electric energy to be converted into heat energy, so the waste of electric energy is large, and the fill light is working. Additional power consumption is required, so the overall energy consumption is high. At the same time, when the temperature rises, the overall signal-to-noise ratio of the identification system will be reduced, which will easily lead to code scanning failure.
