Problems solved by technology

[0005] Although the existing methods can check scoliosis, because most of the existing census methods are based on manual physical detection, manual detection is cumbersome and inefficient when conducting a general survey on a large number of people, especially adolescents. Staff fatigue can also lead to miscalculations and miscalculations
However, the use of X-ray films for census will cause a lot of unnecessary radiation damage to young people, especially children, and the cost is relatively high.

Embodiment Construction

[0065] Such as figure 1 Shown, a kind of human body back scoliosis angle measurement method based on digital image processing comprises the following steps:

[0066] A. Use a digital camera to capture images of the back of the human body, and obtain the following figure 2 In the image shown, the subject needs to stand upright, and the picture includes the uppermost end of the cervical spine to the lower end of the lumbar spine;

[0067] B. Read the image, obtain the height and width information of the image, and the RGB information of each pixel;

[0068] C, carry out image recognition and segmentation processing to the back image of the human body in step B, intercept the region of interest, obtain as follows image 3 In the image shown, the redundant contour interference on both sides is discarded, and the main spine contour part is retained;

[0069] D, convert the intercepted image in step C into a gray value image, obtain as Figure 4 The image shown, and the gray va...

Abstract

The invention discloses a human back scoliosis angle measuring method based on digital image processing. A standing human back image is taken with an ordinary digital camera, then the image is preprocessed to obtain an interested area, graying processing is conducted on the interested area, binarization processing is conducted in the gray level image to obtain a human back contour binary image, denoising processing is conducted on the binary image to obtain spine contour feature points, least square method polynomial fitting is conducted on the feature points to obtain a spine contour fittingcurve, and finally the scoliosis angle is calculated according to the fitting curve. The method is simple and practical, an algorithm is easy to implement, and the aim of measuring the scoliosis anglecan be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of image processing, in particular to a method for measuring the scoliosis angle of the back of a human body based on digital image processing. Background technique [0002] The spine is the central axis of the human body. When scoliosis is severe, it will not only cause abnormal body appearance and motor dysfunction, but also cause cardiopulmonary dysfunction due to thoracic deformity, reduce the quality of life, and seriously affect the physical and mental health of adolescents. If the disease is not detected early and treated actively, it will not only affect the child's body shape and appearance, but also may cause abnormal cardiopulmonary function, premature spine degeneration, pain, and trunk imbalance. Sick children with severe deformities may even suffer early cardiopulmonary failure, leading to death. [0003] Scoliosis, also known as scoliosis, refers to a spinal deformity in which one or several ...
