Abstract

The invention discloses a rapid three-dimensional scanning method for a human foot, and relates to the technical field of three-dimensional scanning and digital analysis. The method includes the steps: calibrating a measuring head by means of internal and external parameter bundle adjustment; projecting speckles to the foot, acquiring a foot image and matching the speckles; performing three-dimensional density point cloud reconstruction by the calibrated measuring head to obtain a three-dimensional foot model; extracting the size of the foot model according to the three-dimensional foot model.According to the rapid three-dimensional scanning method for the human foot, coordinates of foot key points such as an inner ankle point, an outer ankle point, a heel point and a tiptoe point of thehuman foot can be acquired, sizes such as foot sweep, the length of the foot, the length of an outer ankle, foot breadth and heel breadth are automatically extracted and calculated, and scanning speedand precision are high.

Description

technical field

[0001] The invention relates to the technical field of three-dimensional scanning and digital analysis, in particular to a fast three-dimensional scanning method for feet. Background technique

[0002] With the improvement of living standards, people's requirements for footwear products have gradually shifted from simply pursuing the beauty of styles to requirements for comfort. my country has a vast territory. Due to different regions and different growth environments, the foot shapes of people in each region will have their own characteristics. Therefore, footwear companies need to design, develop and sell products for consumers, so that consumers can buy shoes that are more suitable for them. However, the domestic footwear industry still does not have enough basic research on the characteristics of foot shapes in various regions. The traditional shoe-making industry divides leather shoes into men's shoes, women's shoes, and children's shoes, and divides th...
