Method, device, electronic equipment and medium for detecting crooked tongue

Abstract

The present application provides a method, device, electronic equipment and medium for detecting a skewed tongue. After obtaining the image to be detected of the target object, the method detects the head posture of the head area in the image to be detected, and obtains the head position corresponding to the head area. head posture information; and, detect the tongue body area in the detection image to obtain the tongue body information corresponding to the tongue body area; use the preset inclination degree algorithm to calculate the head posture information and tongue body information to obtain the tongue body information of the target object body inclination degree value; if the tongue inclination degree value is greater than the preset inclination threshold, it is determined that the tongue of the target object is a crooked tongue. This method improves the detection accuracy.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular, to a method, device, electronic equipment and medium for detecting a skewed tongue. Background technique [0002] The tongue is naturally protruded, and the tongue body is deviated to one side, left or right and cannot be straightened, which is called a crooked tongue. The tongue muscle on the affected side is paralyzed and unable to contract. When it is stretched a little, the tongue body will be uneven and skewed on both sides. Therefore, when the left tongue muscle is paralyzed, the tip of the tongue will turn to the left, and when the right tongue muscle is paralyzed, the tongue tip will deviate to the right. This disease is common in stroke, that is, cerebrovascular accident. If it is a local disease, it is caused by compression of the hypoglossal nerve or facial nerve paralysis.

Problems solved by technology

[0003] Computer vision analyzes the skew of the tongue and analyzes the skewed tongue, usually through techniques such as skeleton extraction and refinement, method of moments, mid-axis transformation, and straight line fitting. However, these technologies have their own shortcomings, such as skeleton extraction and refinement, and mid-axis transformation. It is only applicable to slender tongues, and the method of moments is only applicable to tongues with better contour symmetry.

[0004] That said, there are certain limitations to the analytical techniques described above.
