Abstract

The invention discloses a measurement method of the scoliosis angle of the back of a human body based on computer vision. The measurement method includes the steps of acquiring a back depth image of a human body by using a depth camera and preprocessing the back depth image of the human body; then performing triangulation processing by using a Lawson algorithm to obtain a three-dimensional reconstruction model of the back of the human body; constructing a contour map of the back surface profile of the human body and combining with the characteristics of a contour line to find a central line of the back of the human body; performing integer interpolation on the central line of the back to obtain the curvature of each point on the central line of the back; solving the length of the spine trunk by the use of anatomical landmark points and obtaining a spine body length expression; and finally substituting into a correlation model to reconstruct a spine central line three-dimensional curve. The reconstruction accuracy is greatly increased, and the reconstruction effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of image processing, in particular to a computer vision-based method for measuring the scoliosis angle of the back of a human body. Background technique [0002] The spine is the central axis of the human body. Once scoliosis occurs, it will not only give people a deformed appearance, but also cause serious mental trauma to children. Spinal deformities that occur in the early years will also affect the development and maturity of children's heart and lungs, and some may also affect the spinal cord and nerves. The incidence of scoliosis in the population is about 1%. In many cases, it has little impact on life in the early stage. Many parents ignore it, and physical examination is not a routine item. As a result, many teenagers miss the opportunity to correct easily, causing health problems that affect the quality of life throughout their lives. [0003] Scoliosis, also known as scoliosis, is caused by the ...
