A skin image detection device and a skin image analysis system based on the same

Abstract

The invention provides a skin image detection device. The skin image detection device comprises a light source part, an amplification objective lens, a first polarizing film and a second polarizing film, Wherein the light source part is arranged behind the first polarizing film and is used for emitting light; Wherein the polarization direction of the first polarizing film is perpendicular to the second polarizing film, the light rays irradiate the surface of the skin through the first polarizing film, and the second polarizing film is used for filtering out the light directly reflected from the surface of the skin; And the amplification objective lens is arranged behind the second polaroid. The invention also provides a skin image analysis system based on the device. Through the skin imagedetection device and the skin image analysis system, a clear original image can be observed without direct contact with the skin, manual squeezing of the skin is reduced, the skin image detection device and the skin image analysis system are particularly suitable for image observation of the head and face part, especially at mucosa of mouth, eyes, nose and the like and sensitive skin, and the visibility of skin lesion is improved.

Description

technical field [0001] The invention relates to a skin image detection device and a skin image analysis system. Background technique [0002] Since the optical density and refractive index of the skin are different from air, a large part of the light irradiating the skin surface is directly reflected by the stratum corneum. In addition, part is absorbed by the skin, and only a small amount enters the skin through scattering, so it is difficult to directly see the lower part of the epidermis, the junction of the epidermis, the papillary layer, and the dermis with the naked eye. [0003] In order to be able to see the tissue structure under the skin, the existing technical solutions mainly adopt traditional infiltration dermatoscope and traditional capillary scope. Among them, the infiltration dermatoscope needs to use a coupling agent, that is, an infiltration solution to eliminate the influence of reflected light on the skin surface to obtain imaging of the subcutaneous tis...

AI Technical Summary

Problems solved by technology

Among them, the infiltration dermatoscope needs to use a coupling agent, that is, an infiltration solution to eliminate the influence of reflected light on the skin surface to obtain imaging of the subcutaneous tissue. However, since the infiltration solution is required, it may cause contact dermatitis and iatrogenic cross-infection, so There is a risk of infection, and the imaging effect is not ideal at the same time, it is difficult to observe a clear original image

On the other hand, the capillary microscope will directly contact the skin and cause compression to the skin, and it is also difficult to obtain a clear original image
