Description

Technical Field

[0001] The utility model relates to the technical field of data tongue diagnosis auxiliary equipment, in particular to a three-dimensional data (especially three-dimensional data of the tongue) acquisition device. Background Art

[0002] Tongue diagnosis plays an important role in traditional Chinese medicine and is one of the important means to understand the human body. It is widely used in clinical diagnosis and treatment of traditional Chinese medicine. However, in the traditional tongue diagnosis process, most doctors observe and judge with the naked eye, which is subjective and limited. Doctors' observation of tongue shape, color and other characteristics is often affected by subjective factors, which can easily lead to misdiagnosis or missed diagnosis.

[0003] At present, most of the tongue diagnosis auxiliary equipment on the market are two-dimensional image acquisition devices. Such equipment uses a camera or a camera to collect two-dimensional images of the tongue, and analyzes the shape, color and other characteristics of the tongue through software to assist doctors in diagnosis. One of the common devices is the intelligent tongue diagnosis instrument, which uses a high-definition camera to capture tongue images, and then uses a built-in algorithm to analyze the characteristics of the tongue, tongue coating and other characteristics to provide a reference for doctors. However, the collected two-dimensional images have the disadvantages of incomplete information and being easily affected by light and angle. Three-dimensional imaging equipment can obtain three-dimensional morphological data of the tongue and provide richer information. Existing three-dimensional tongue diagnosis equipment includes equipment using technical principles such as structured light and laser scanning. The three-dimensional morphological data of the tongue is obtained by emitting structured light and collecting reflected light, and then the tongue quality, tongue coating and other characteristics are analyzed by algorithms for diagnosis.
