Why Does a Foot 3D Scanner Sometimes Produce Inaccurate Assessment Results After Purchase?

Many customers who purchase a foot 3D scanner initially feel that the measurement reports are rich in data and that all the parameters look impressive.

However, after serving customers for a period of time, they gradually start receiving feedback that the measurements are inaccurate. This is especially true when assessing flat feet and high arches, where the results are often inaccurate and sometimes even show huge differences.

In theory, foot 3D scanners should all be high-tech devices, so such problems should not occur.

In fact, this has a lot to do with the data acquisition method used by the foot 3D scanner.

Currently, most foot 3D scanners on the market use structured light or cameras to collect data. However, the arch of the foot is naturally a blind spot, making it difficult for this type of light to capture the height of the arch. The arch height displayed by the software is basically supplemented through interpolation calculations by the software.

If you only look at the 3D model, because the missing data has been filled in through software interpolation, the data appears complete. However, the arch height data in this part is not actual measured data.

This is the root cause of the large errors or even incorrect assessments when evaluating flat feet and high arches.

Because they cannot truly measure arch height, these devices can only rely on footprint area to calculate and determine whether someone has flat feet or high arches.

This assessment method can easily lead to misjudgments. For example, people with wider or fleshier feet, especially children, are easily misdiagnosed as having flat feet. Meanwhile, people with thinner feet have smaller footprints, even though their actual arch height is not that high. However, they may still be assessed as having moderate or even severe high arches.

However, 3DOE's foot scanner uses laser scanning to collect data. Both feet are scanned from 16 different angles, enabling full-range measurement without blind spots. The arch height data collected is not supplemented or calculated through software interpolation, but is actual measured data, with an accuracy of within 0.5 mm.

3DOE's measurement reports provide a multi-dimensional assessment of flat feet and high arches. They use a combined analysis of arch height, vertical navicular drop, medial longitudinal arch angle, and arch intercept distance to make comprehensive assessments. The measurement results are accurate, objective, and highly precise, with minimal deviations across repeated measurements, allowing them to truly reflect foot shape and foot health status.

Therefore, when purchasing equipment, we should not look at the price alone. We also need to consider whether the data collected by the equipment is genuine and objective, and whether it can fully meet the requirements of the intended project. Choosing the right product is what matters most.
