A plantar scanner is a core instrument for custom insoles that measures the three-dimensional contour, dimensional data, and morphological characteristics of the sole of the foot.
The plantar scanner is built with high-precision laser transmitting and receiving components.
Currently, the popular laser types on the market include: line laser scanning, point laser scanning, and area laser scanning.
These laser types can capture every contour and dimensional detail of the sole when the human foot is placed stationary or moving slowly.
The scanning accuracy of lasers is usually around 0.5 millimeters.
After scanning the data, the supporting software performs modeling processing and generates a three-dimensional model of the sole, including the length and width of the sole, arch height, heel shape, forefoot thickness, etc.
The laser principles and core application scenarios of the plantar scanner are as follows:
1. Application at the level of laser scanning principle
At the level of laser scanning principle, the laser emitting component projects laser onto the sole, and the receiving component captures the reflected signal, calculates the spatial coordinates of each point on the sole, and realizes three-dimensional contour reconstruction and accurate data collection.
2. Application in the standardization of usage procedures
It guides the user’s foot placement to ensure scanning accuracy, such as adjusting the foot standing posture and fixing the scanning range, and can also conduct preliminary verification and correction of the scanned data.
3. Application in customized adaptation optimization
For example, analyze the plantar data obtained by scanning to match the corresponding insole materials and structures.
Optimize the scanning data of special foot shapes to improve the insole adaptability.
4. Application in equipment operation and maintenance
For example, it is applied to standardize the laser emission power, regularly calibrate the scanning accuracy, extend the service life of the equipment, and ensure the consistency and reliability of each scanning data.
