Multispectral tongue picture collecting device

Abstract

The invention discloses a multispectral tongue picture collecting device which comprises a box body, wherein a tongue body detection opening is formed in one side of the box body; a digital camera is arranged on the other side of the box body through penetrating through the box body wall; a light source is arranged on the inner surface of the box body; an optical lens is arranged inside the box body; the tongue body detection opening and the digital camera are positioned in the image conjugate positions on the two sides of the optical lens respectively; and a light splitting device is arranged between the optical lens and the digital camera. The multispectral tongue picture collecting device provided by the invention acquires the multispectral information of the detected tongue body at last through acquiring multispectral images of the tongue body; through combination of three dimensional information of a first dimensional light spectrum and a second dimensional image of the tongue body, physiological and pathological information brought by the tongue body can be reflected, so that more objective information can be provided for doctors of Chinese medicine for tongue diagnosis, and the accuracy in clinical diagnosis of the doctors of Chinese medicine can be improved; and meanwhile through the comparison of the tongue body three dimensional information of a patient in different stages, objective references can be provided for evaluation of clinical curative effect of doctors of Chinese medicine.

Description

technical field [0001] The invention relates to medical equipment, in particular to a multispectral tongue image collection device. Background technique [0002] As a part of traditional Chinese medicine inspection, tongue diagnosis plays a very important role in diagnosing diseases. The theory of viscera is one of the basic theories of Chinese medicine, and viscera refers to the image of the viscera and the physiological phenomenon that the internal activities of the viscera are manifested on the body surface. Tongue image is also the external manifestation of Tibetan image directly reflected on the surface of the tongue. It can be seen that tongue diagnosis has high clinical diagnostic value and plays an important role in TCM diagnosis. [0003] With the development of science and technology, more and more attention has been paid to the objectification of tongue diagnosis. The development of tongue diagnostic equipment has also received extensive attention, and some rese...
