Flat feet and high arches may sound like just foot shape problems, but they are actually closely related to our physical health. Fatigue when walking, inexplicable knee pain, and shoes that don’t fit well are often caused by abnormal foot structure.
Traditional visual or manual evaluation is neither accurate nor intuitive. The device I want to introduce today is a smart measurement tool used by more and more medical institutions and foot health centers in recent years – a foot shape 3D laser scanner.
This device uses non-contact laser scanning technology to accurately record the 3D structural data of the foot in just a few seconds, including key parameters such as instep height, arch shape, sole width, and toe arrangement.
Compared with traditional measurement methods, the foot shape 3D laser scanner has higher accuracy, stronger data analysis capabilities, and more intuitive visualization results.
Its working process is mainly divided into three steps:
The first step is laser stereo modeling.
The user only needs to stand barefoot on the scanning platform, and the system will emit multiple sets of laser lines to form a scanned image on the surface of the foot. The device generates a complete 3D model of the foot through laser reflection and camera acquisition.
The second step is to automatically identify the arch structure.
The system has a built-in standard foot database. By comparing the longitudinal profile curve of the sole, it can quickly determine whether the user has a normal foot, flat feet or high arches.
Whether the low arch causes the sole to collapse, or the high arch causes unstable walking, it can be clearly presented through the scanning results.
The third step is to generate a personalized report.
After the scan is completed, the system will automatically output a detailed report containing arch height, left and right foot comparison, foot pressure distribution trend, etc., which is convenient for doctors or foot health managers to formulate personalized orthopedic suggestions and rehabilitation plans.
Foot-shaped 3D laser scanners are currently widely used in many fields. For example, in children’s growth and development monitoring, parents can promptly find out whether their children have developmental flat feet;
In the field of sports medicine, athletes can adjust their gait through scanning results to reduce the risk of injury; for diabetic patients, this scan can also assist in identifying high-pressure points on the foot and prevent the occurrence of plantar ulcers.
In addition, the foot-shaped scanner can also be connected to the insole customization system to achieve true foot-measuring customization. Compared with choosing insoles based solely on shoe size, this method is more scientific, more accurate, and more effective in improving foot discomfort.
