The plantar scanner uses high-precision 3D morphological modeling technology to demonstrate multiple values in the fields of medical health, consumer customization, industrial design, etc. The core application scenarios are as follows:
I. Medical health field
（1）. Diagnosis of abnormal foot structure
Acquire geometric parameters such as arch height and calcaneal inclination angle through laser or structured light scanning, accurately identify structural lesions such as flat feet and high arch feet, with an error range of ≤±0.5mm.
The 3D model supports the calculation of indicators such as hallux valgus angle and metatarsal alignment offset, and assists in the formulation of orthopedic surgery plans.
（2）. Orthopedic device design and adaptation
Based on the 3D data of the foot (such as STL format model), 3D prints layered structure orthopedic insoles to achieve accurate matching of arch support and sole contact surface.
Compare the 3D models before and after surgery to quantitatively evaluate the effect of bone correction (such as arch height increase ≥3mm).
2. Consumption and Industry
（1）. Personalized Shoe Customization
Scan 20+ parameters such as foot length and foot circumference to generate a 3D foot model, optimize the shoe last design, and reduce the redundant space in the shoe (fitting error ≤±0.5 yards).
Design a dedicated shoe cavity structure for special foot shapes (such as wide feet and high insteps) to improve comfort and functionality.
（2）. Shoe Product Research and Development
Use a massive foot shape database (such as 100,000+ samples) to analyze regional foot morphology differences and optimize the sole arc design and material distribution.
3. Scientific Research and Biomechanical Research
（1）. Construction of Foot Shape Database
Collect 3D foot data of different age and gender groups, establish a foot arch development curve model, and study the correlation between foot shape and athletic ability.
（2）. Prevention of Sports Injuries
Analyze the stability of athletes’ ankles in combination with the 3D foot shape, and optimize the design of protective gear to reduce the risk of ligament sprains.
（3）. Technology evolution direction
High-precision dynamic scanning: The new device can capture the three-dimensional changes of the dynamic contraction and extension of the foot, improving the accuracy of sports scene modeling
