Description

Projection device for tongue detection and projection system thereof Technical Field The invention relates to the technical field of image acquisition and processing equipment, in particular to a projection device for tongue surface detection and a projection system thereof. Background Tongue diagnosis is a simple and effective method for assisting diagnosis and identification by observing changes of color and form of tongue, and is one of important contents of inspection. With the development of internet technology, tongue remote diagnosis and treatment is realized, patients collect tongue information at home, in a subordinate hospital or at other collection points, and the tongue information is remotely projected to a display device through the internet, so that experienced doctors can perform more accurate diagnosis. For remote diagnosis, the accuracy of image acquisition directly influences the accuracy of diagnosis, and when tongue image acquisition is carried out, the influence of ambient light is great, meanwhile, liquid on the tongue can also generate reflection of light to generate excessive exposure areas, so that the influence of ambient light can be overcome, the influence of liquid reflection can be reduced, and the accuracy of tongue information acquisition is improved by collecting tongue information through a camera bellows assisted by a proper light source. The camera and the light source in the camera bellows are relatively fixed in position, but because the body type and the posture are different when in use, the shooting angle and the polishing angle are difficult to be kept at the optimal angles, the image acquisition quality is influenced, and the diagnosis is influenced. The camera bellows is generally closed, and when the tongue information of the user is collected, the face of the user is closely attached to the opening of the camera bellows, so that a relatively closed space is formed in the camera bellows. The space in the camera bellows is relatively small, so that the inner space of the camera bellows is filled with gas exhaled by a user, and the exhaled gas is likely to carry germs to infect subsequent users. Secondly, the user may not cough independently during the inspection, a large amount of droplets may be exhaled by the cough, the space in the camera bellows is narrow, the droplets may adhere to the lens or the inner wall, the droplets adhering to the lens may affect the quality of the picture, and the germs carried by the droplets adhering to the inner wall of the camera bellows may infect the next user.
