Laser principle of the 3D foot scanner and the differences and advantages compared to the foot mirro

The principle, data dimensions and application method of 3D laser foot scanner are very different from that of foot mirror. 

I. Differences in Imaging and Data Collection Methods 

3D laser scanners projects laser or structural light onto the surface of the foot for multi-angle imaging and modeling to generate a complete 3D foot data model. It can accurately capture areas such as the instep, arch, sole and side of the shoe, measurement accuracy up to millimetres. 

Foot mirrors rely mainly on optical reflection or contact imaging technology. When looking at the outline of the foot through a mirror or transparent tablet, only 2D or near-2D information about the surface of the foot can be obtained, and there is not enough 3D data. 

ii. Differences in Data Depth and structure presentation 

3D laser scanners can obtain information on foot length, width, instep height, arch height, toe alignment and overall outline of the foot. It supports left-foot and right-foot independent modeling, symmetric analysis, and can save data for buyback or customization. 

Foot mirrors mainly reflect the contact area of the foot and judge the force of the arch. It doesnot provide information instep height of the instep or the three-dimensional structure of the foot. 

III. Differences in Accuracy and functionality 

3D laser scanners have high measurement accuracy and can be applied for insole or sole last customization, foot health assessments, children's foot monitoring and sports rehabilitation. Scanning is contactless, fast, and data can be archived. 

Foot mirrors are easy to operate, cost-effective and suitable for quick observation of arch or sole load-bearing areas. However, it cannot be used for precise measurement or in-depth analysis. 

IV. INTRODUCTION Different Applicable Scenarios and values 

3D laser scanners are suitable for high-end shoe stores, rehabilitation institutions, orthopaedic centers, sports and fitness stores, etc., for professional evaluation, personalized customization and long-term tracking of foot types. 

Foot goggles are more suitable for general shoe stores and are used for basic screening or experience demonstrations for initial observation or reference. 

In general, the foot mirror provides information about the surface of the two-dimensional foot, while the 3D laser scanner provides a complete 3D foot structure. 3D scanners have significant advantages in scenarios that require precise measurements, health assessments, or customization of services; for simple observation or basic screening, footwear is an appropriate option.
