Problems solved by technology

However, the price is that the three primary color imaging technology can only obtain the three variable values ​​of red, green and blue, and the amount of information is less
In addition, the sensitive spectral ranges of the three imaging units of cameras, scanners and other equipment used for three-primary color imaging cross each other, resulting in red, green, and blue variables containing more redundant information
In summary, there is a problem that the existing technology cannot take into account the accuracy and the convenience of operation at the same time

Abstract

The invention discloses a signal characterization method of a visual array sensor. The full spectrum information of the visual array sensor is obtained by use of a hyperspectral imaging technology, and a spectrum difference value under a characteristic wavelength is extracted from the full spectrum information and applied to the signal characterization of the visual array sensor. The signal characterization method is capable of improving the detection accuracy and the stability of the visual array sensor and can be applied to the fields of multi-component gas detection, food inspection and the like.

Description

technical field [0001] The invention relates to a signal characterization method of a visual array sensor, in particular to a method for using hyperspectral imaging technology to perform signal characterization of a visual array sensor, thereby improving its detection effect. Background technique [0002] Visual array sensing technology is a new type of sensing technology developed in recent years. It uses a variety of chemical chromogens such as porphyrins, metal porphyrins, and pH indicators with certain specific recognition capabilities to react with gases to produce characteristic responses. Signal, through the signal processing system to obtain the characteristic spectrum of the sample to be tested, and then perform qualitative or quantitative analysis. [0003] As the sensing unit of the visual array sensor, the color of the chemical chromogenic agent will change before and after the action of the detected object. The molecular structure of the colorant changes to cha...
