Abstract

The invention belongs to the technical field of machine vision and provides a color recognition method and system. The method is characterized in that the normalization color data of a target pixel point relative to a reference background is calculated, the correlation between the color value of the target pixel point and the color value of each standard sample in multiple pre-stored standard samples is calculated according to the normalization color data of the target pixel point and the normalization color data of the multiple pre-stored standard samples, and selecting the color value, with the highest correlation with the color value of the target pixel point, of the standard sample to serve as the real color value of the target pixel point. By the color recognition method, the color value of a target substance can be recognized in a good data stability, high accuracy and low cost manner.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a color recognition method and system. Background technique [0002] Color recognition is an extremely important link in industrial and agricultural production. Color is essentially the integral effect of material radiation or reflection spectral distribution and human eyes or photoelectric sensors. The color recognition of the human eye not only depends on the ambient illuminance, but is also related to photochemical neural processes and psychological responses. It is usually difficult to describe the color quantitatively and standardly. The color recognition of photoelectric sensors is not only dependent on the lighting environment, but also related to the response of the sensor and the sensor image algorithm. Therefore, the stability of the color data obtained in different lighting environments or in different color recognition systems is poor, and it may e...
