Flat foot detection instrument: the use principle and advantages of plantar laser 3D scanner

To put it simply, the foot laser 3D scanner is a precision instrument that uses laser + optical sensing technology to model, measure and analyze your feet.

Its working process is roughly divided into three steps:

Step 1: Laser scanning modeling

You only need to stand barefoot on the scanning platform, and the instrument will emit multiple laser beams to "scan" the true contours of the sole and arch in just a few seconds.

These lasers are reflected back, and combined with the data captured by the high-resolution camera, the system will generate a three-dimensional image of your sole, including parameters such as foot shape, arch height, and instep contour.

Step 2: System intelligent analysis

The scan results will be compared with the standard foot database, and the artificial intelligence algorithm will be used to analyze whether your arch height, sole force distribution, and arch structure are normal.

If the arch collapses significantly, the contact area is too large, and the arch height is lower than the reference value, you will be prompted to be **"flat feet"** or "low arches", and the degree will be marked (mild, moderate, severe).

Step 3: Generate a personalized foot report

The system will output a foot test report with pictures and texts, including:

Arch height analysis

3D foot structure

Left and right foot symmetry comparison

Customized insole suggestions or rehabilitation training suggestions

Why is it more reliable than traditional methods?

Traditional methods such as "stepping on ink board", "visual arch measurement", "pressing palpation" often rely on manual judgment and have large subjective errors.

The foot laser 3D scanner has the following four advantages:

Non-invasive and non-sensing, completed in a few seconds

The whole process does not touch the skin, no need to plug wires or apply glue, just stand barefoot and wait for the results.

Accuracy up to millimeter level

The laser measurement error is extremely low, and it can accurately capture even 1mm subtle changes in the arch of the foot, which is suitable for medical diagnosis and sports analysis.

Data visualization, clear at a glance

It is no longer the doctor "says you are", you can't see it, the graphics, models, and curves issued by the instrument allow you to clearly understand every dimension of your foot.

Can be used to customize insoles and rehabilitation programs

The scan results can be connected to the smart insole system to customize personalized arch support for your feet, truly achieving "filling where there is collapse".

Who is suitable for this test?

People who often have foot pain and swollen feet after standing for a long time

Children and adolescents, to prevent abnormal arches during development

Elderly people, to prevent falls and gait problems

People who run, play basketball, exercise, etc.

People with waist and knee pain, and those who sit or stand for a long time
