Abstract
Description
Technical Field
[0001] This utility model relates to the field of human organ imaging technology, and in particular to an ear image acquisition device. Background Technology
[0002] In Traditional Chinese Medicine (TCM) theory, based on the meridian system and holistic view, the ear is considered closely related to the internal organs and meridians of the whole body, reflecting the body's health status. This has led to a unique method of diagnosis: ear diagnosis, which uses changes in the shape, color, and feel of the auricle to aid in disease diagnosis. For example: a pale color may indicate insufficient Qi and blood or a cold syndrome; a reddish color may be related to a heat syndrome or inflammation; a bluish color may reflect Qi stagnation and blood stasis or a cold syndrome; a blackish color may be related to kidney deficiency or cold-dampness; a thick auricle may be related to phlegm-dampness or obesity; a thin auricle may indicate insufficient Qi and blood or a weak constitution; a deformed auricle may be related to congenital deficiencies or chronic diseases; a cold auricle may indicate Yang deficiency or a cold syndrome; a hot auricle may be related to Yin deficiency or a heat syndrome; earlobe folds may be related to coronary heart disease or cardiovascular diseases; and a thick earlobe may be related to phlegm-dampness or metabolic problems. Therefore, TCM can use the color, shape, and temperature of the ear to diagnose diseases.
[0003] Currently, ear image acquisition typically involves using cameras or mobile phones to photograph, archive, and study the human ear. However, due to the lack of specialized ear image acquisition devices, issues such as hand tremors, head movements, and lighting often lead to significant variations in the angle and position of the captured images. This results in ears of varying sizes and angles, color differences, and even reduced clarity, making ear image acquisition non-standardized and hindering subsequent research. Therefore, it is necessary to design an ear image acquisition device to ensure the accuracy and stability of the captured ear images. Utility Model Content
