Problems solved by technology

Typical representatives of pressure distribution measurement sensors include Xsensor pressure measurement system using capacitive sensing technology, Tekscan pressure distribution measurement system using piezoresistive sensing technology and FSA (Force Sensing Array) pressure testing system using piezoresistive pressure sensing technology , these sensors need to be composed of thousands of tiny pressure sensors, each sensor unit can only measure a pressure, the position accuracy is determined by the area of ​​each sensor unit, and when the position accuracy is higher, the volume of the tiny pressure sensor unit Must be smaller, more expensive, and this type of sensor cannot measure tangential forces

Embodiment Construction

[0061] see figure 1 , in the present embodiment, the gait sole pressure distribution measurement method is to combine the visual sensor with the gait measurement device, utilize the visual sensor to obtain the position and shape of the sole of the foot, and obtain the information of each main pressure action position 5 of the sole of the foot; use the gait measurement device Detect and obtain the magnitude of each main pressure on the sole of the foot.

[0062] The main pressure action positions 5 on the soles of the feet are: one pressure action position in the phalanx area is the first phalanx area of ​​the foot, or there are two pressure action positions in the phalanx area, which are the first phalanx area and the second to fifth phalanx area of ​​the foot; the metatarsal area There are two pressure acting positions on the first metatarsal area and the second to fifth metatarsal areas, or three pressure acting positions on the metatarsal area are the first metatarsal area,...

Abstract

The invention discloses a method for measuring distribution of pressures of gait soles. The method is characterized in that vision sensors are combined with gait measuring devices, the locations and the shapes of the soles are acquired by the aid of the vision sensors, and information of various main pressure acting locations of the soles is acquired by the aid of the vision sensors; the various main pressures of the soles are acquired by the gait measuring devices by means of detection.

Description

technical field [0001] The invention belongs to the technical field of sensing, and more specifically relates to a method for measuring gait plantar pressure distribution. Background technique [0002] For the measurement of plantar pressure distribution during gait, the current main method is to attach multiple tiny pressure sensors on a certain plane to determine the distribution position and size of plantar pressure. Typical representatives of pressure distribution measurement sensors include Xsensor pressure measurement system using capacitive sensing technology, Tekscan pressure distribution measurement system using piezoresistive sensing technology and FSA (Force Sensing Array) pressure testing system using piezoresistive pressure sensing technology , these sensors need to be composed of thousands of tiny pressure sensors, each sensor unit can only measure a pressure, the position accuracy is determined by the area of ​​each sensor unit, and when the position accuracy ...
