Embodiment Construction

[0018] In order to make the present invention more comprehensible, preferred embodiments are described in detail below with accompanying drawings.

[0019] like figure 1 As shown, the system used in the present invention mainly includes: optical fiber temperature sensor 1, fiber grating strain sensor 2, conventional instrument 3, information sharing module 4, human body test investigation module 5, information sharing and data analysis module 6 based on the above information collection, Pre-judgment system 7, and fit conclusion module 8. Among them, the optical fiber temperature sensor 1 and the optical fiber grating strain sensor 2 are used to collect the temperature of the shoe surface and the strain information under dynamic and static states. The conventional instrument 3 is used to collect some basic shoe information and foot size information. The information sharing module 4 organizes and analyzes all the temperature and strain information. The human body test investi...

Abstract

On the basis of a fiber sensor sensing principle and particularly on the basis of the fact that a Prague fiber grating sensor has the advantages that the measurement sensitivity is high, and high-frequency signals can be acquired, the invention provides a shoe fit evaluation method based on fiber sensing technology. The fiber grating sensor after packaged is fixed at a different position of a shoe, deformation of the shoe in a static state and in a dynamic state is reflected, and when the shoe is over larger or over small, the sensor is not much sensitive to a deformation signal. According to the corresponding data acquisition method and the corresponding data analysis method based on the fiber grating sensor, shoe fit can be judged scientifically.

Description

technical field [0001] The invention relates to a footwear fit evaluation method based on optical fiber grating sensing technology, which objectively and rapidly evaluates footwear fit in a quantitative manner, and provides a new system for footwear fit evaluation. Background technique [0002] In recent years, conventional footwear fit judgment methods are generally based on 3D scanning technology for extracting foot dimensions. Kouchi et al. used free deformation technology to simulate the three-dimensional foot shape of the human body, which laid the foundation for the development of low-cost scanners. Luximo and others studied a low-cost three-dimensional scanning system, and carried out corresponding development and verification to replace the existing expensive foot three-dimensional scanning system. Other relevant research results in recent years are mainly focused on the development of new scanning systems for fit or comfort. Generally, the fit is judged based on st...
