Human body foot type arch detection method

Abstract

The invention relates to the technical field of human body foot type detection, and provides a human body foot type arch detection method. The human body foot type arch detection method comprises the following steps: utilizing a physical digitalizer to acquire discrete point cloud data of a foot to be detected; generating a grid curved surface; enabling the grid curved surface to generate a closed curved surface; establishing a local coordinate system; solving plane intersection points of the closed curved surface and an equation that z minus 5 is equal to 0; performing the first place connection of the obtained intersection points to generate a closed curve; using that x equals to a as a divisional plane, wherein a expresses a real number, and partitioning into two point sets; finding the maximal intersection points (A and B) of coordinate y; marking the midpoint of a connecting line of A and B as E, drawing a straight line perpendicular to the straight line AB, and calculating two intersection points (F and G) of the vertical straight line and the closed curve line; calculating a length ratio r of the line segments EF and FG; comparing the length ratio r with the arch judging standard to determine the arch type. The human body foot type arch detection method disclosed by the invention improves the human body foot type arch detection reliability, and is high in accuracy, zero in misdiagnosis rate and high in efficiency.

Description

technical field [0001] The invention relates to the technical field of human foot shape detection, in particular to a human foot shape arch detection method. Background technique [0002] The obvious characteristics of a strong foot are that the toes are stretched without being squeezed, flexible and powerful, the front part of the sole of the foot is well-developed, the arch of the foot is fully formed, and it is elastic and powerful. This type of foot has strong grip, good balance and stability, and is not easy to fall. However, many modern urban children have slender feet, weak foot muscles, flat soles, weak grip, poor balance stability and shock resistance, and are prone to falls and injuries, and even other parts of the body, so it can be accurately detected. Find out the arch type, and then have a pair of strong feet through correction, which is very meaningful for improving the quality of life and physical development of children. [0003] At present, any detection ...

AI Technical Summary

Problems solved by technology

[0003] At present, any testing organization determines the shape of the arch of the foot by observing the soles of the feet with the naked eye, which has the problems of large errors, long time-consuming, low efficiency, and high misdiagnosis rate.
