Tongue body dynamic three-dimensional reconstruction system oriented to tongue inspection in traditional Chinese medicine

Abstract

The invention provides a tongue body dynamic three-dimensional reconstruction system oriented to tongue inspection in traditional Chinese medicine. According to the tongue body dynamic three-dimensional reconstruction system, dynamic information acquisition and three-dimensional reconstruction of a tongue body can be achieved. The tongue body dynamic three-dimensional reconstruction system comprises a spherical box body, a jaw support, a lifting table, a camera light shield, a face-shaped light shield, a multi-light-source system, an image acquisition system, a synchronous control circuit and a computer, wherein the multi-light-source system is composed of eight LED light sources, eight light source supports and a base, and the image acquisition system is composed of a high-speed camera and an image acquisition card. Openings are formed in the left hemisphere portion of the spherical box body and the right hemisphere portion of the spherical box body respectively, one of the openings is a camera hole used for installation of the image acquisition device, and the other opening is a hole allowing the examined tongue body to extend into. The eight light sources are evenly distributed on the vertical circumference, taking the sphere center as the circle center, of the box body, each light source faces towards the tongue body and irradiates the center of the tongue body, and the direction of each light source can be adjusted. The synchronous control circuit generates two sets of signals, one of the two sets of signals control circulating powering on of the eight light sources, the other set of signals trigger a camera shutter, a frame of image is taken through the camera each time the light sources in one direction are powered on, and synchronous acquisition is completed.

Description

technical field [0001] The invention relates to a tongue body dynamic three-dimensional reconstruction system for tongue diagnosis in traditional Chinese medicine, which can realize dynamic information collection and three-dimensional reconstruction of the tongue body. Background technique [0002] Tongue diagnosis is one of the very important methods in TCM diagnosis. In traditional TCM tongue diagnosis, doctors generally observe the patient’s tongue and make a diagnosis based on their own experience and knowledge. It is related to knowledge level, experience skills, and even the mental state at the time of diagnosis, which is objectively affected by the light and temperature of the consulting room. The diagnosis process adopts the traditional naked eye observation and text description, without the corresponding record and analysis of tongue image data, which brings a lot of inconvenience to clinical, teaching and scientific research, and restricts the development and promo...
