Three-dimensional image reconstruction method

Abstract

The invention discloses a three-dimensional image reconstruction method. The method comprises the following steps of step1, carrying out image pair acquisition under a highlight environment and acquiring a calibration board image pair and a tongue image pair; step2, carrying out image preprocessing and using the tongue image pair satisfying a baseline constraint to provide an initial characteristic point for linear increase; step3, using an improved linear seed point increase stereo matching algorithm to acquire a disparity map; step4, extracting and filtering an area of interest of the disparity map and acquiring an area-of-interest disparity map; and step5, carrying out point cloud reconstruction and model reconstruction, and acquiring a tongue image point cloud graph and a complete tongue model. The method has advantages that tongue images can be collected in a period which is less than tongue vibration and 0.1626mm reconstruction precision can be realized; a real tongue shape and color information can be simultaneously acquired; and an effective scientific basis is provided for tongue-diagnosis three-dimensional quantification and objectification research and the method can be used for medical diagnosis.

Description

technical field [0001] The invention relates to the field of tongue diagnosis in traditional Chinese medicine, in particular to a three-dimensional image reconstruction method. Background technique [0002] Tongue diagnosis is an important part of the four diagnostic methods of traditional Chinese medicine. Tongue diagnosis is recorded in many Chinese medical works. It is one of the important methods of syndrome differentiation and treatment in traditional Chinese medicine. Famous doctors of all dynasties have attached great importance to the research of tongue diagnosis, so that they can be continuously improved and developed. Form a TCM tongue diagnosis system. [0003] Traditional Chinese medicine believes that "the tongue is the lord of the heart, and the fur is the clear sign of the stomach", "what is inside must be shaped outside", different areas of the tongue are directly or indirectly connected with the internal organs of the human body, and changes in the tongue im...

Problems solved by technology

[0006] In order to solve the problem that the real tongue dynamic characteristics and resolution are not compatible with the existing three-dimensional tongue image reconstruction method for the purpose of medical diagnosis, the present invention discloses a three-dimensional image reconstruction method, which solves the problems of the dynamic characteristics and the resolution of the real tongue reconstruction. The problem of not having both high resolution and providing a good lighting environment makes the image clarity greatly improved, which can be used for medical diagnosis
