Description

technical field [0001] The invention relates to the field of foot measurement, in particular to a foot measurement device, a multi-dimensional foot feature analysis system and method. Background technique [0002] The existing foot measurement technology is mainly divided into manual measurement and automatic measurement. Manual measurement has defects such as low efficiency, large error, and few measurable parameters, and has been gradually replaced by automatic measurement technology. [0003] Automatic measurement technology can be further divided into three-dimensional foot shape measurement technology based on image stitching and plantar pressure distribution measurement technology. Among them, the three-dimensional foot shape measurement technology based on image stitching can only measure the characteristic parameters of the outer contour of the foot, and the measurement accuracy is limited by the camera installation accuracy. After a period of use, the relative posit...

[0002] The existing foot measurement technology is mainly divided into manual measurement and automatic measurement. Manual measurement has defects such as low efficiency, large error, and few measurable parameters, and has been gradually replaced by automatic measurement technology.

[0003] Automatic measurement technology can be further divided into three-dimensional foot shape measurement technology based on image stitching and plantar pressure distribution measurement technology. Among them, the three-dimensional foot shape measurement technology based on image stitching can only measure the characteristic parameters of the outer contour of the foot, and the measurement accuracy is limited by the camera installation accuracy. After a period of use, the relative position of the camera changes and the accuracy of 3D modeling decreases; the plantar pressure distribution measurement technology mostly uses dot-matrix piezoresistive flexible force-sensitive sensors to collect plantar pressure distribution information. Such sensors exist Disadvantages such as poor hysteresis and increased pressure value measured for a long time
