The foot 3D measuring instrument is a high-precision foot measuring device that uses technologies such as laser scanning, structured light, optical measurement or depth camera to reconstruct the foot morphology in three dimensions.

Compared with traditional foot shape measurement methods (such as plaster molding and footprint measurement), 3D measurement technology provides more accurate, faster and more objective data, and is widely used in medicine, sports science, footwear manufacturing, rehabilitation engineering and other fields.

With the development of digital technology and intelligent manufacturing, the application scope of foot 3D measuring instruments continues to expand, not only playing a role in personalized orthopedics and sports optimization, but also having a profound impact on large-scale footwear production, foot health management and other industries.

The foot 3D measuring instrument mainly uses the following technologies to collect foot morphology data:

Laser scanning, using laser beams to measure the surface morphology of the foot and provide high-precision point cloud data;

Structured light scanning, projecting grating patterns onto the foot, calculating the three-dimensional shape through light deformation;

Optical measurement, using multi-angle cameras to capture foot images and generate three-dimensional models through algorithms; Depth camera scanning, measuring foot depth information based on infrared or ToF (time of flight) technology.

These technologies can achieve millimeter-level accuracy and realize non-contact rapid measurement to ensure the accuracy and stability of data.

The application of foot 3D measuring instruments in the medical field is mainly concentrated in orthopedic medicine, foot disease diagnosis, rehabilitation treatment and other aspects.

In the customization of orthopedic insoles and orthopedic shoes, it can collect foot morphology data, analyze parameters such as arch height and calcaneal angle, and combine gait analysis with plantar pressure testing to design personalized orthopedic insoles or orthopedic shoes, which are suitable for patients with flat feet, high arches, diabetic feet, hallux valgus and other foot diseases.

In terms of diabetic foot and ulcer prevention, 3D scanning is used to evaluate foot pressure distribution, predict high-risk areas, prevent ulcer formation, and combine smart insole technology to provide pressure relief solutions for diabetic patients.

In the field of foot rehabilitation assessment, it can be used for postoperative recovery monitoring, record foot morphology changes, evaluate rehabilitation progress, and be applied to patients with nerve damage to monitor changes in foot structure and assist rehabilitation training.

Foot 3D measuring instruments are widely used in the field of sports science for athlete gait optimization, shoe design, injury prevention and other aspects. In sports gait analysis, it can be combined with a gait analyzer to evaluate the athlete's plantar force pattern, stride, landing method, etc., optimize running posture through data, improve sports performance, and reduce injury risks.

In terms of customized sports insoles, insoles with different hardness and support structures are designed according to the athlete's foot data, and exclusive sports insoles are manufactured using 3D printing technology to improve comfort and sports stability.

In addition, it can also be used for injury prevention and recovery, monitoring foot changes after sports injuries, such as Achilles tendonitis, plantar fasciitis, etc., combined with rehabilitation training, optimizing support equipment, and improving recovery efficiency.

The three-dimensional foot measuring instrument is an important part of smart footwear manufacturing, helping personalized footwear customization and large-scale industrial production.

In the field of high-end customized shoes, it can obtain user foot shape data through three-dimensional scanning, accurately customize personalized shoes, and combine CAD/CAM technology to optimize the design of shoe lasts, insoles, and soles.

In the intelligent shoe matching system, combined with big data analysis, the most suitable shoes are recommended according to the user's foot shape, which is suitable for online shoe sales, improves purchase matching and reduces the return rate. In addition, it can also be used to build a shoe last database based on scan data, and combine AI algorithms to improve the accuracy and comfort of shoe design.

In the field of rehabilitation engineering, foot three-dimensional measuring instruments are widely used in the customization and adaptation of prostheses and orthotics. By collecting patient foot data, the most anatomically consistent prosthesis can be customized for amputees, and combined with 3D printing technology, the comfort and support effect of orthotics can be improved.

In addition, it can also be used for foot health management of the elderly, regularly scan foot shape, monitor the collapse of the arch and bone degeneration of the elderly, and combine with rehabilitation insoles to provide better walking support
