Intelligent dynamic and static foot-shape data acquisition device and method thereof

Abstract

The invention discloses an intelligent dynamic and static foot shape data acquisition device, which includes socks and a data processing module, and also includes multiple groups of intelligent adaptive materials for measuring the deformation state and pressure of the foot shape. Sexual materials are all embedded in the warp strands of the socks, and the data processing module is located at the sock opening of the socks; it also includes a power circuit, which provides working power for the data acquisition device, and each group The output terminals of the intelligent adaptive material are respectively connected to the corresponding input terminals of the data processing module. By embedding intelligent adaptive materials into socks to form a collection device, the collection device can be fitted to the user's feet to the greatest extent, so that the user can accurately collect foot data in different scenarios, that is, the 3D model of the foot and the Dynamic pressure distribution data of various parts of the upper body (sole, toe, sole, arch, heel and ankle).

Description

technical field [0001] The invention relates to the field of foot shape measurement, in particular to an intelligent dynamic and static foot shape data acquisition device and a method thereof. Background technique [0002] Foot shape data is an important reference for shoe customization, and the accuracy of foot shape data collection directly affects the customization of shoes. At present, foot shape data collection includes manual measurement, structured light measurement, stereo vision measurement and laser measurement, etc., which rely on experience or technology to achieve measurement. These measurement methods are mainly based on static scene data collection. [0003] For example, traditional foot shape data collection relies on experience, and manual measurement of soles, arches, ankles, heels, etc. has low accuracy, especially for special foot shapes. Low problem, and the traditional acquisition method can not be dynamic measurement. [0004] For example, the Chines...

Problems solved by technology

[0003] For example, traditional foot shape data collection relies on experience, and manual measurement of soles, arches, ankles, heels, etc. has low accuracy, especially for special foot shapes. Low problem, and the traditional acquisition method is also unable to carry out dynamic measurement

[0004] For example, the Chinese patent application number: 201120084573.9 discloses "a wireless gait measuring instrument based on plantar pressure". Pressure points to collect data of gait pressure; since the thin-film piezoresistive pressure sensors are distributed at the pressure points only to grasp the key points, however, the gait pressure of each person's feet is different, so through the thin-film piezoresistive The gait pressure data collected by the pressure sensor is not accurate and practical

[0005] For example, the Chinese patent with the application number: 201510788582.9 discloses "a foot shape three-dimensional data measurement system". The measurement system reflects and projects part of the streaked light projected by the projector to the foot to be measured and the projector through two mirrors. On the opposite surface, in a global world coordinate system, the three-dimensional measurement of the peripheral surface of the foot from the instep to the sole of the foot is carried out simultaneously in three directions, and then the measurement data in the three directions are directly fused to obtain Three-dimensional data of foot shape; since the measurement is based on a global world coordinate system, the measurement data in three directions does not need to find matching points for data splicing, so the speed and accuracy of measurement can be greatly improved, but it cannot solve the dynamic problem Acquisition of 3D foot pressure distribution data
