Embodiment Construction

[0036] In order to make the technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0037] figure 1 It is a flow chart of a method for boxing speed detection provided by an embodiment of the present invention, such as figure 1 As shown, the method includes:

[0038] Step 1: Initialization.

[0039] This step includes assigning the initial value of the three-dimensional acceleration of gravity as the measured value of the acceleration sensor, and setting the azimuth as 0.

[0040] Step 2: Acquire acceleration, gyroscope, and magnetic sensor measurement values.

[0041] This step includes reading measurements from acceleration sensors, gyroscope sensors, and magnetic sensors, where...

Abstract

The invention provides a motion measuring method and a motion measuring device. The method comprises the following steps: obtaining measured values of an acceleration sensor, a gyroscope sensor and a magnetic sensor of a motion terminal; obtaining the three-dimensional gravitational acceleration and azimuth angle of relative carrier coordinates of the motion terminal; obtaining the three-dimensional motion acceleration of the relative carrier coordinates; obtaining the three-dimensional motion acceleration of relative earth coordinates; obtaining the acceleration, the speed, the displacement and the stereoscopic motion track of the relative earth coordinates. According to the invention, a specific process calculation method is adopted to greatly reduce various errors produced in inertial motion posture calculation and subsequent computations, so that brand new, convenient, rapid and efficient measuring method and device are provided for body motions such as boxing, kicking and the like of human bodies and similar motions of objects in natural world.

Description

technical field [0001] The invention relates to the fields of inertial navigation and motion measurement, and is very suitable for the measurement and description of second-level short-term fast motion. Background technique [0002] In current boxing sports, there is no device directly attached to boxers or boxing gloves that can directly and independently measure parameters such as acceleration, speed, and trajectory of boxing. Contents of the invention [0003] The present invention mainly utilizes the MEMS sensor technology, combined with the process method described in the present invention, to invent a device for measuring and describing the short-term and fast object movement of boxing. The present invention uses a computer software program algorithm to integrate the motion accelerations of the three axial directions perpendicular to each other on the basis of the earth coordinates to obtain a three-dimensional velocity, and then integrate to obtain a three-dimension...
