Speed control method and device for running machine

Abstract

The embodiment of the invention provides a speed control method and device for a running machine and belongs to the technical field of running machines. The speed control method comprises the steps that the three-dimensional spatial data of two knee-joints of a runner within the preset time are obtained; the current motion amplitude parameter value of the runner is obtained on the basis of the three-dimensional spatial data of the two knee-joints of the runner within the preset time and compared with the average motion amplitude parameter value to obtain the acceleration or deceleration will of the runner; and the speed of the running machine is controlled according to the acceleration or deceleration will of the runner. In this way, the runner can conveniently, quickly and freely control the speed of the running machine according to the acceleration or deceleration will, so that the convenience and adaptability of the running machine are improved.

Description

technical field [0001] The invention relates to the technical field of treadmills, in particular to a method and device for controlling the speed of a treadmill. Background technique [0002] At present, the speed control of traditional treadmills mainly depends on the control handle, the speed adjustment button on the panel, or according to the speed control mode set in advance. Existing virtual reality treadmills control the speed of the treadmill by capturing the spatial position data of the foot joints. [0003] The traditional treadmill has the following problems: 1) The speed control is unnatural, and the speed control is done by hand, which cannot truly simulate the speed control method of people running in a natural environment; 2) The speed control is inconvenient, and it is difficult to control it at will during the running process Speed, which affects the realism of virtual reality scene roaming. [0004] Existing virtual reality treadmills have the following pr...

[0003] The traditional treadmill has the following problems: 1) The speed control is unnatural, and the speed control is done by hand, which cannot truly simulate the speed control method of people running in a natural environment; 2) The speed control is inconvenient, and it is difficult to control it at will during the running process Speed, which affects the realism of virtual reality scene roaming

[0004] Existing virtual reality treadmills have the following problems: 1) There are many foot joints, and the motion capture is more complicated; 2) During the running process, the cushioning and shock absorption of the treadmill will affect the foot movement data, reducing the accuracy of the captured data. 3) When the motion capture equipment takes into account the upper limbs and feet of the human body, the field of view is relatively large, and it needs to be installed farther away from the human body, which increases the invalid length ratio of the treadmill.
