Technology and Application of Three-Dimensional Foot Scanner Combined with AI Algorithm to Generate Personalized Foot Profile Report
I. Technical Principles and Implementation
The technical system of a three-dimensional foot scanner combined with AI algorithm to generate personalized foot profile reports mainly includes three core steps:
Data Acquisition: Using structured light scanning or laser scanning technology, complete measurement of 20 three-dimensional foot data points within 10–15 seconds, with sub-millimeter accuracy (±0.5mm).
AI Analysis and Processing: Intelligent analysis of the scanned data through deep learning algorithms, including:
- Foot type classification (Egyptian foot, Roman foot, Greek foot, etc.)
- Arch index calculation (high arch, normal arch, flatfoot)
- Gait abnormality detection (overpronation, supination, etc.)
- Health risk assessment
Report Generation: Generate a personalized report within 5 seconds, including 3D foot model, dimensional data, and health suggestions, and recommend suitable shoe styles and insoles.
II. Technical Breakthroughs and Innovations
Algorithm Innovation: The integrated algorithm addresses the missed diagnosis and misdiagnosis issues of traditional arch index (AI), significantly improving foot type judgment accuracy, validated by 582 sample cases.
Precision Improvement: AI algorithm enhances scanning accuracy from ±2mm to ±0.5mm, capable of identifying foot feature changes at the 0.5mm level.
Function Expansion: Extends from simple measurement to health assessment, such as detecting hallux valgus and abnormal plantar pressure distribution, and provides corrective suggestions.
III. Application Scenarios and Value
E-Commerce Customization: Platforms such as Tmall and JD.com have deployed 3D foot scanning services, enabling a “foot-measured shoe” personalized shopping experience, reducing return rates by 25%.
Medical Rehabilitation: Used for diagnosis and orthotic insole customization for foot conditions such as flatfoot and high arch, for example, ICB orthotic insoles combined with plantar proprioception stimulation training can improve gait in children with cerebral palsy.
Sports Science: Provides professional foot analysis for athletes, optimizing sports shoe design and improving athletic performance.
