Tongue diagnosis imaging system based on infrared image and visible light image registration and image registration method

Abstract

The invention relates to a tongue diagnosis imaging system based on infrared image and visible light image registration and an image registration method. The tongue diagnosis imaging system comprises an infrared imaging assembly, a visible light imaging assembly and a main control assembly. An infrared imaging assembly is provided; the visible light imaging assembly is provided with a visible light assembly adjusting mechanism, and the visible light imager can be driven by the visible light assembly adjusting mechanism to adjust the position; and the main control assembly is provided with an adjusting mechanism control module, is connected with and controls the postures of the infrared assembly adjusting mechanism and the visible light assembly adjusting mechanism, and is used for registering the infrared image acquired by the infrared imaging assembly and the visible light image acquired by the visible light imaging assembly to form a registered image. The tongue diagnosis imaging system based on registration of the infrared image and the visible light image is convenient to carry and high in cost performance, can carry out automatic positioning to shoot and register the infrared image and the visible light image of the tongue of a patient, is suitable for various tongue diagnosis imaging occasions, and is a good supplement for the current tongue diagnosis imaging industry.

Description

technical field [0001] The invention relates to the field of tongue diagnostic imaging equipment, in particular to a tongue diagnostic imaging system based on registration of infrared images and visible light images. Background technique [0002] Tongue image is an item that often needs to be analyzed and diagnosed in TCM diagnosis and treatment. At present, tongue images in TCM diagnosis are obtained through related imaging systems, such as SLR cameras. In scientific research, infrared thermal imaging is also used to take pictures of the tongue to analyze its temperature field distribution. However, there is currently no instrument that can simultaneously register the infrared image and the visible light image of the tongue for diagnosis. In recent years, with the development of society, people's material living standards have been greatly improved, and most people can't control their diet and work well, resulting in an increasing incidence of related diseases that can ca...

Problems solved by technology

[0004] However, although the visible light tongue image can be used to analyze the color change of the tongue coating, it lacks information on the temperature distribution of the tongue; while the infrared thermal imaging of the tongue can obtain its temperature field information, but the overall infrared image of the tongue has a low resolution and lacks specific information. localization of lesion
