Real-person shoe type copying device and shoe tree manufacturing method based on single-eye multi-angle-of-view robot vision

Abstract

The invention discloses a real-person shoe type copying device based on single-eye multi-angle-of-view robot vision. The device comprises a single-eye multi-angle-of-view 3D (Three-dimensional) vision box and a computer, wherein the single-eye multi-angle-of-view 3D vision box is used for shooting images of a foot of a real person at five different angles of view; the computer is used for achieving the 3D reconstruction of the foot of the real person and automatically generating a 3D printing file; a plane mirror rectangular bucket-type cavity is formed inside the single-eye multi-angle-of-view 3D vision box and consists of four trapezoidal mirror planes; the upper part of a mirror body is large, and the lower part of the mirror body is small; the mirror planes face the inner side of a cavity body; a light source used for providing uniform soft lighting for the foot of the real person is arranged at the lower part of the plane mirror rectangular bucket-type cavity; cameras used for obtaining the images of the foot of the real person at multiple angles of view according to the refraction and reflection principle of the mirror planes are further arranged in the single-eye multi-angle-of-view 3D vision box; the computer comprises a single-eye multi-angle-of-view 3D vision calibrating unit, an image division, conversion and correction unit, a real person foot surface shape measurement unit and an automatic STL (Standard Template Library) file generation unit. The invention further discloses a shoe tree manufacturing method based on the single-eye multi-angle-of-view robot vision.

Description

Technical field [0001] The invention relates to the application of monocular multi-view machine vision in shoe last digitization, and belongs to the fields of shoe sample and shoe last personalized design, shoe last / real foot integrated processing, shoe last automatic production, etc., in particular to a single Multi-view machine vision real-life shoe model reproduction device and shoe last manufacturing method. Background technique [0002] When buying shoes, people often need to try on different models of shoes to find shoes that fit their feet as much as possible, so that in most cases, human feet must passively adapt to the fixed size and shape of the shoes. In fact, the shape of the feet that belong to the foot length range corresponding to the same yard length is very different. Even the left and right feet of the same person are not completely mirror-symmetrical. There may also be length, fat and thin, arch height, etc. Different degrees of difference, even the left and r...
