Embodiment

[0025] Concrete implementation steps of the present invention are as follows:

[0026] Step 1: Acquisition of sequential spectral images: The imaging spectrometer used to obtain sequential spectral images has many types of imaging spectrometers, and imaging spectrometers with different principles have different ways of obtaining spectral images. In the present invention, the imaging spectrometer based on liquid crystal tunable filter Taking a spectrometer as an example, the acquisition of sequence spectral images and the extraction process of spectral curves are explained.

[0027] The composition of the imaging spectrometer based on liquid crystal tunable filter is as follows: figure 1 As shown, under the action of the drive controller, the liquid crystal tunable filter filters the optical signal from the target to be measured, and only transmits the optical signal in the set wavelength range; The optical signal is imaged and stored on the computer through the image data acq...

Abstract

The invention discloses a whitening effect judging method based on spectral imaging. The whitening effect judging method comprises the following steps: (a), acquiring a standard spectral curve; (b), acquiring the spectral feature curves of skin before and after whitening; (c), carrying out spectral analysis. The method is formed by perfectly combining a spectral imaging technology and a spectral analysis technology, and the spectral reflectivity curves of different positions of the skin can be obtained by the spectral imaging and analysis technology. As the spectral reflectivity curves of the pigment-free skin of different people in a waveband range of 450-650nm are basically consistent, the spectral reflectivity curve can be used as the standard spectral curve. The whitening effect is quantitatively evaluated through comparing the similarity of the spectral feature curves of skin before and after whitening and the standard spectral curve, the problems of uncertainty and slow evaluating speed of the existing whitening effect evaluating method depending on subjective consciousness are solved, and the purpose of rapidly obtaining the whitening effect is achieved.

Description

technical field [0001] The invention relates to an evaluation method for skin whitening effect, in particular to a method for judging the whitening effect based on spectral imaging. Background technique [0002] Whitening treatment refers to controlling and inhibiting melanin production by acting on a certain stage of skin melanin formation and metabolic pathway, thereby reducing skin chroma or lightening pigmentation, so as to achieve the purpose of skin whitening. In recent years, with the development of the economy and the improvement of living standards, people pay more and more attention to the natural and therapeutic whitening of the skin. How to objectively and quantitatively evaluate the whitening effect, there is still no evidence in our country, and it is urgent to formulate the whitening effect evaluation standard in our country. [0003] There are different types of human skin colors such as white, yellow, black, and brown. For the determination of skin color c...
