Can a 3D foot laser scanner identify arch height?

A 3D foot laser scanner can identify arch height, but it mainly relies on static structural measurements.

This type of device performs high-precision 3D modeling of the foot to obtain parameters such as foot length, foot width, instep height, toe alignment, heel tilt angle, and the overall contour of the foot arch.

Based on the modeling results, it can calculate arch height and arch index, and make a preliminary judgment on whether the foot is high-arched, normal-arched, or flat.

It should be noted that the 3D scanner can only measure the static shape of the arch and cannot reflect dynamic changes in the arch during walking or weight-bearing.

In other words, it cannot assess whether the arch collapses or bears weight abnormally during daily activities. This type of function requires the help of a plantar pressure plate.

A plantar pressure plate can record the pressure distribution of the soles during standing or walking, the trajectory of the center of gravity, and the performance of the arch during dynamic movement.

It can determine whether the arch functions normally under load, making it an ideal tool for evaluating gait, balance, and foot function.

A simple comparison is as follows:

The 3D scanner mainly analyzes the structural shape of the foot and is suitable for static foot shape analysis and insole customization.

The plantar pressure plate evaluates the actual performance of the foot during use and is suitable for gait analysis and rehabilitation guidance.

If you want to assess arch height, the laser scanner can provide structural data.

If you also want to know whether the arch collapses or weakens during walking or standing, it is recommended to use the plantar pressure system at the same time to obtain more comprehensive results.
