Abstract

The invention discloses a tooth crack detection method and system and relates to the technical field of tooth detection. The method comprises the following steps: acquiring a tooth image taken by a near-infrared camera; preprocessing the tooth image so as to obtain a gray image; performing edge binaryzation on the gray image so as to obtain an edge point; performing Hough transform on the edge point so as to obtain a rho value of the edge point in a Hough space; processing the rho value of the Hough space by using a Moore voting method so as to obtain pixel points of a tooth crack; and addingcolor marks to the pixel point of the tooth crack, and outputting a tooth crack image. The method is based on the tooth image taken by the near-infrared camera, according to the characteristic that shapes of tooth cracks are mostly approximate to a straight line, the image is subjected to edge binaryzation, and a straight line crack of a tooth can be found in a mode with the combination of the Hough transform method and the Moore voting method; and real-time precision detection on the tooth crack can be achieved, and the method has the characteristics of no radiation, no detection time limit and high reliability.

Description

technical field [0001] The invention relates to the technical field of tooth detection, in particular to a tooth crack detection method and system. Background technique [0002] With the continuous improvement of people's quality of life, dental health has gradually attracted people's attention. Dental diseases can be detected early through early detection, and most dental diseases can be cured if treated in time. Existing tooth crack detection technologies are mainly based on X-ray imaging, computerized tomography (Computed Tomography, CT) detection and quantitative photoconductive fluorescence technology. Among them, X-rays are widely used in medical treatment and can be used to evaluate the internal conditions of teeth. However, the dose of X-rays that living tissues can receive is limited, and frequent detection cannot be performed. CT detection method is very effective for the tooth cracks that have been formed, but lacks sensitivity and predictability for early tooth...
