Equipment for detecting foot size – 3D foot scanner

1. Technical principles and core functions

Based on the optical non-contact measurement technology, the foot 3D scanner mainly uses the following three principles to achieve millimeter-level precision foot size detection:

Laser scanning: emit laser beams and receive reflected signals, and use time-of-flight (TOF) or triangulation to calculate the coordinates of the foot surface point cloud;

Core functions include:

Static size measurement: accurately obtain more than 20 parameters such as foot length, foot width, arch height, foot circumference, etc.;

3D modeling: generate a 1:1 digital foot model, support rotation, profile analysis and data export.

2. Application scenarios

Medical and health field

Foot deformity screening: identify structural abnormalities such as flat feet and high arches, and assist in the customization of orthopedic insoles;

Postoperative evaluation: track foot morphological changes and optimize rehabilitation plans.

Footwear industry ‌

Personalized shoemaking ‌: Customize shoe lasts based on 3D data to improve the fit and comfort of shoes;

Sports equipment optimization ‌: Match special shoes for athletes to reduce the risk of sports injuries.

Scientific research and education ‌

Biomechanics research ‌: Provide basic data such as foot development and morphological evolution;

Teaching demonstration ‌: Visually display the anatomical structure of the foot through a 3D model.

III. Technical advantages

High precision and high efficiency ‌

Single scanning time ≤ 20 seconds, accuracy up to 0.5mm;

Support complete data collection of complex surfaces (such as arches and heels).

Non-contact safety measurement ‌

Use near-infrared or visible light bands to avoid foot deformation caused by contact measurement;

Ergonomic design, standing scanning improves user experience.

Multi-dimensional data compatibility ‌

Supports output in formats such as STL and OBJ, and is compatible with CAD/CAM software and 3D printing equipment;

Can be expanded to integrate a robotic arm or turntable to achieve batch automatic scanning.

The 3D foot scanner has become a core tool in the fields of medical health, industrial manufacturing and scientific research through its optical digital technology and multi-scenario adaptability, promoting the transformation of foot data from experience to precision.
