- Equipment principle and core functions
The foot 3D scanner uses optical scanning, laser scanning or structured light projection technology to capture the foot shape in a non-contact manner, generate a high-precision 3D model, and measure data such as arch height and foot contour.
Its core functions include:
Arch shape analysis: quantify arch height and symmetry, and judge abnormalities such as flat feet and high arches.
3D modeling: Generate a three-dimensional model of the foot to provide data support for customized insoles or orthotics.
- Accurate use of operation procedures
- Equipment and environment preparation
Check the cleanliness of the scanner lens, power supply and data cable connection stability.
Choose a place with uniform light and no strong light interference to ensure a stable ground.
- Start the software and select a scanning mode (such as static standing).
- Preparation of the subject
Take off shoes and socks, clean your feet and keep them dry to avoid stains affecting the scanning accuracy.
Standing or sitting posture must meet the requirements of the equipment, with the center of gravity evenly distributed on both feet, and the body upright to avoid tilting.
- Scanning and data acquisition
After starting the scan, the subject needs to remain still for 5-20 seconds (the duration varies slightly for different devices) and wait for the three-dimensional point cloud data to be generated.
- Data processing and result interpretation
The software automatically generates an arch height curve and a three-dimensional model, marking abnormal areas (such as arch collapse or high arch deformity).
Combine clinical standards (such as arch index) to determine the foot type, and output diagnostic suggestions or customized insole solutions.
III. Precautions for use
- Operating specifications
Regularly calibrate the equipment to avoid data deviation caused by hardware errors.
The subject needs to relax the muscles to avoid changing the natural shape of the foot due to tension.
- Factors affecting the results
Foot edema, trauma or temporary posture errors may affect the accuracy of the measurement. It is recommended to take the average of multiple scans.
- Application scenario adaptation
Medical diagnosis needs to be combined with other clinical examinations (such as X-rays) for comprehensive evaluation.
In the field of sports science, gait analysis can be combined to optimize sports shoe design or training programs.
IV. Typical application scenarios
Flat foot/high arch foot screening: rapid diagnosis through arch height and pressure distribution.
Customized insole production: accurate adaptation to foot support needs based on 3D model data.
Sports injury prevention: analysis of athlete foot mechanical characteristics and optimization of training plans.
By standardizing the operating process and integrating multi-dimensional data, the plantar 3D scanner can significantly improve the accuracy and clinical value of arch judgment.
