Multi-point three-dimensional tongue image acquisition device for tongue diagnosis instrument

Abstract

The invention discloses a multi-point three-dimensional tongue image acquisition unit for tongue diagnosis equipment. The multi-point three-dimensional tongue image acquisition unit comprises a hollow hemispherical support with a downward opening. The hemispherical support is 25cm in radius. Four tongue-side cameras are evenly arranged in front of the bottom of the hemispherical support. Chord length between each two adjacent tongue-side cameras is 6cm. A line connecting the center of a line of the middle two tongue-side cameras and the center of sphere of the hemispherical support is perpendicular to the line of the two cameras. The top center of the hemispherical support is provided with a tongue-top camera. The hemispherical support is provided with at least 50 point light sources which are evenly arranged on the hemispherical support. The five cameras on the hemispherical support are used for multi-viewpoint three-dimensional acquisition of tongue images at the distance of distinctive vision of eyes, three-dimensional images of tongues can be displayed completely, errors and mechanical noise and the like caused by motion of the cameras can be avoided, and judging and analyzing illness state thoroughly and completely is convenient for doctors.

Description

technical field [0001] The invention relates to a tongue diagnosis device, in particular to a multi-point three-dimensional tongue image acquisition device for a tongue diagnosis instrument. Background technique [0002] Tongue diagnosis is a unique diagnostic method of TCM, which fully reflects the traditional experience and characteristics of TCM diagnosis. "Nei Jing" said: "Looking and knowing is called God." This shows the great diagnostic value of inspection in clinical syndrome differentiation and treatment. Looking at the tongue can understand the ups and downs of qi and blood in viscera, the depth of pathogenic factors, and the progress and retreat of disease changes, which is of great significance for prescribing medication and judging prognosis. Sometimes, it is more intuitive and reliable than other diagnosis methods, because the tongue body is exposed, and the tongue image changes rapidly and obviously, which is a sensitive external image response to changes in...

Problems solved by technology

However, the current tongue image collection is in the stage of plane images, which cannot completely present the three-dimensional shape of the tongue itself, resulting in missing information, which is not conducive to the doctor's diagnosis, and may cause misdiagnosis, etc., or the camera moves to collect multiple images to synthesize a three-dimensional image, but According to photography knowledge, when people look at the scene, the farther the scene is, the smaller the angle between the left and right eyes is, the smaller the viewing angle difference is, and the weaker the three-dimensional effect is, so when collecting multiple images, the camera needs to be moved, left camera position --> scene- ->The angle between the right camera and the three should be between 0 and 12 degrees, but the dynamic range is small and it is difficult to control accurately, which makes the composite effect unsatisfactory
