Description

Method for designing shoe tree according to plantar image analysis data

Technical Field

The invention relates to a method for designing a shoe tree according to foot sole image analysis data, which is applied to the industries of shoe making and shoe tree making.

Background

The last is a model for making a shoe, and its size and shape are related to the inner space of the shoe. With the development of social economy, consumers pay more attention to the comfort and fit of shoes, and personalized customization becomes a fashion. China also has a lot of related researches in the field. One type is the traditional pure manual operation, and foot shape measurement is performed by using a micrometer, a vernier caliper, a tape laying ruler and the like, but the operation is performed by people with certain experience, and the interference of artificial factors is excessive. One type is to use three-dimensional foot type scanning measurement, although feeling is modern, the three-dimensional measurement device can not be accurately used for designing and developing the shoe tree due to lack of an accurate positioning system, so that the designed shoe tree still depends on the personal feeling of a designer to judge whether the shoe tree is suitable, scientific and standard size control is also lacked, the cost is high, and the market is difficult to apply. At present, China still has many problems in the real personalized customization.

Disclosure of Invention
