Embodiment Construction

[0031] The implementation of the method for identifying the color difference of spray marks of the present invention will be described in detail below with reference to the accompanying drawings.

[0032] Signal processing is a general term for the processing of various types of electrical signals according to various expected purposes and requirements. The processing of analog signals is called analog signal processing, and the processing of digital signals is called digital signal processing. The so-called "signal processing" is the process of processing the signal recorded on a certain medium in order to extract useful information. It is a general term for the processing processes of signal extraction, transformation, analysis, and synthesis.

[0033] In order to use the signal, people have to process it. For example, when the electrical signal is weak, it needs to be amplified; when it is mixed with noise, it needs to be filtered; when the frequency is not suitable for tr...

Abstract

The invention relates to a sprayed mark color difference identification system, and the system comprises a sprayed mark processing structure which comprises a position adjustment device, a sprayed mark execution device, a vertical supporting platform, and a horizontal supporting platform; the color extraction device is used for acquiring each color component value of each constituent pixel in the image block where the current mark spraying content is located; and the chromatic aberration analysis device is used for performing arithmetic mean value calculation on the numerical values of the color components of the same type corresponding to the constituent pixels in the image blocks, and sending out a color loss unrecognized command when the result obtained by calculation is in a set numerical value interval of the color components of the corresponding type. The invention further relates to a mark spraying color difference identification method. According to the invention, on the basis of introducing a numerical value matching mechanism of each color channel based on the sprayed mark content and a targeted image optimization mechanism, an electronic color difference detection mode is adopted to replace a current artificial color difference detection mode, so that the reliability and effectiveness of on-site sprayed mark operation are improved.

Description

technical field [0001] The invention relates to the field of color difference detection, in particular to a system and method for identifying color difference of spray marks. Background technique [0002] When imaging with white light, in addition to the five monochromatic aberrations produced by each monochromatic light, there will also be dispersion caused by different refractive indices of different colored lights, so that different colored lights have different propagation paths, thus showing The aberration caused by the difference in the optical path of different colors of light is called chromatic aberration. Chromatic aberration can be divided into positional chromatic aberration and magnification chromatic aberration due to different properties. [0003] Although the optical system has a series of aberrations, it is generally impossible to completely correct and eliminate them. However, since the human eye and all other optical receivers also have certain sensitivi...
