Description

Acquisition device for hyperspectral and structured light images of tongue surface diagnosis in traditional Chinese medicine Technical Field The utility model belongs to the technical field of image acquisition equipment, and particularly relates to an acquisition device for hyperspectral and structured light images of tongue and face diagnosis in traditional Chinese medicine. Background Traditional Chinese medicine inspection mainly relies on visual observation of an operator by a doctor and diagnosis and treatment experience of the doctor to judge the health condition or illness of the operator. In the inspection process of traditional Chinese medicine, doctors infer the functional state, pathological changes and the like of viscera in the body by observing the fine changes of the whole face, local five sense organs, tongue and other parts of the person to be inspected. These subtle changes typically include, for example, the tone and texture of the skin of the face or tongue, the condition of blood circulation under the skin, the pigment distribution of the skin, etc. However, this traditional method of inspection of traditional Chinese medicine needs to rely on the experience and diagnosis level of doctors on one hand, and on the other hand, environmental conditions during inspection, such as light conditions, temperature changes, etc., are also important factors affecting the judgment of the doctor about the condition of the caller. This results in significant subjectivity and limitations in the traditional approach to inspection of traditional Chinese medicine. At present, along with the development of optical imaging technology and the wide application of the optical imaging technology in the medical field, the inspection technology of traditional Chinese medicine is gradually developed into digitization and intellectualization through the fusion with the optical imaging technology. For example, the high-resolution image is obtained by a visible light technology to replace subjective observation of doctors, and the surface characteristics such as tone, texture and the like of the target skin can be accurately captured by image data. However, the study limited by the intellectualization and digitization of inspection of traditional Chinese medicine is still in the initial basic research stage. In particular, the problem of how to combine the technique of optical imaging and its equipment with the inspection of traditional Chinese medicine in a diversified manner to obtain multidimensional biological information about the skin of the face and tongue of the person to be inspected lacks viable technical solutions and intensive research. In view of the foregoing, there is a need to propose a novel device for collecting hyperspectral and structured light images for tongue diagnosis in traditional Chinese medicine to solve the above problems in whole or in part. Disclosure of utility model In order to solve at least one aspect of the above-mentioned problems and defects in the prior art, an embodiment of the present utility model provides an acquisition device for hyperspectral and structured light images for tongue inspection of traditional Chinese medicine, which integrates a hyperspectral camera, a structured light camera and a visible light camera into one acquisition device, and simultaneously acquires a biomarker image, a three-dimensional contour image and a color image of multispectral imaging after image acquisition of the face and tongue of an acquired person, thereby providing objective, detailed and multidimensional tongue image data for the inspection of traditional Chinese medicine to improve the accuracy and efficiency of the inspection of traditional Chinese medicine.
