Problems solved by technology

[0005] So far, the structure of the existing stride measurement equipment is relatively complicated, which is not conducive to the popularization and use of navigation and positioning; the existing simple stride measurement method has low accuracy and cannot accurately measure the stride on slopes. The measurement method requires the support of historical data, requires high hardware resources, and takes a long time to process, so it is difficult to implement in embedded devices

Abstract

The invention discloses a pedestrian stride measuring system which comprises a waist measuring device 1, a thigh measuring device 2, a shank measuring device 3, a foot surface measuring device 4 and a gateway 5, wherein the waist measuring device 1, the thigh measuring device 2, the shank measuring device 3 and the foot surface measuring device 4 are respectively used for measuring pedestrian gait measurement data during gait period, and the measurement data are transmitted to the gateway 5 and a PC (personal computer) by wireless communication. The system has the advantages of small size, simple structure, low power consumption, convenience in extension by wireless communication, capability of simultaneously measuring a plurality of people, low cost and the like. Historical data support is omitted, the pedestrian stride of a level road can be accurately measured, and the pedestrian stride of a slope road can also be accurately measured.

Description

technical field [0001] The invention mainly relates to the field of pedestrian gait measurement, in particular to a pedestrian stride measurement method and system. Background technique [0002] The stride length during pedestrian walking is of great significance for medical gait analysis and pedestrian navigation and positioning. Therefore, how to obtain accurate pedestrian stride length has become a basic problem that needs to be solved in many application fields. [0003] Using traditional measurement devices, such as the paper "Experimental Research on Human Gait Model" "Chinese Doctoral Dissertation Full-text Database, Zhao Lingyan, Page 41-64", the angle meter is installed on the joints of the pedestrian's lower limbs, and the angle of the joint is measured by the angle meter , and then use the joint angle to calculate the pedestrian stride, this method is complicated in equipment and difficult to count the data; the stride can be accurately calculated by using the cam...
