Abstract: Since the existing methods of human foot outline three-dimensional reconstruction have the problems of low accuracy, poor robustness, high cost, and do not meet the actual requirements of the foot biomechanics research etc, a foot parameter measurement system which uses optical measurement technology and realizes non-contact measurement has been designed. On one hand, the system uses plantar scanning technology to construct the point cloud of plantar, segments plantar pressure area, and calculates the relevant parameters of plantar; on the other hand, the system uses line structured light to scan the foot surface to construct point cloud of foot surface, fuses into a whole foot contour point cloud, and finally, the system measures the series of foot parameters according to the definition of foot biomechanics. By the construction of the corresponding hardware platform, the measurements of multiple groups of foot are made, and the experimental results show that the system can finish foot 3D reconstruction quickly and accurately while has good robustness.

Key words: measurement of foot parameters, three-dimensional reconstruction of foot surface, line structured light scanning, plantar scanning
