Monochromatic illumination and auxiliary image processing system

Abstract

The invention discloses a monochromatic illumination and auxiliary image processing system which comprises an ARM processor and an image collection module. The input end of the ARM processor is connected with an image collection module via an FIFO memory module, a communication port of the ARM processor is connected with an RS232 module, the output end of the ARM processor is connected with an Ethernet module via an RJ45 interface, the control end of the ARM processor is connected with a PC via a USB interface chip, the image collection module is internally provided with a data collection card, and data of the ARM processor is connected with the PC via a signal preprocessing module. A tongue and fur separation method in the traditional Chinese medicine based on a monochromatic light sourceis used, tone images in which three primary colors serve as the monochromatic light source are registered with an image collected by a white light source and subtracted, the tongue is separated fromthe fur, image processing is assisted, information of the fur position is obtained, and a tongue surface with the vivid feeling can be reconstructed.

Description

technical field [0001] The invention relates to the technical field of image processing systems for tongue and face instruments, in particular to a monochrome lighting and auxiliary image processing system. Background technique [0002] Tongue diagnosis is one of the important contents of inspection in traditional Chinese medicine, and it occupies a pivotal position in the theoretical system of traditional Chinese medicine and clinical diagnosis and treatment practice. At present, tongue diagnosis mainly relies on the tongue-and-face instrument, but there are still some problems in the image processing of the current tongue-and-face instrument. Defects: [0003] (1) The traditional TCM tongue diagnosis is mainly based on the analysis and judgment of the patient's tongue shape, tongue state, tongue color, fur color, and fur texture by the doctor through naked eye observation. This judgment often relies on the doctor's personal experience and lacks objective data Judgment res...

Problems solved by technology

[0003] (1) The traditional TCM tongue diagnosis is mainly based on the analysis and judgment of the patient's tongue shape, tongue state, tongue color, fur color, and fur texture by the doctor through naked eye observation. This judgment often relies on the doctor's personal experience and lacks objective data Judgment restricts the inheritance and development of tongue diagnosis;

[0004] (2) In recent decades, the objective research of tongue diagnosis has been widely valued. At present, these researches are all focused on the analysis based on 2D tongue images. 3D information perceived in body time;

This method is expensive and inconvenient to carry, and it is difficult to meet the requirements of practical applications.
