Embodiment Construction

[0052] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0053] refer to figure 1 , shows a flow chart of the steps of Embodiment 1 of a method for measuring limb length according to the present invention, which may specifically include the following steps:

[0054] Step 101, obtaining the rotation angle of the limb;

[0055] The present invention can acquire human body motion data through a plurality of inertial sensors placed on various parts of the body. Specifically, the inertial sensor can be placed on the top of the head, back, crotch, left and right shoulders, elbows of the left and right upper arms, wrists of the left and right forearms, finger ends of the left and right hands, knees of the left and right thighs, left and right The ankles of the lower legs and the ...

Abstract

An embodiment of the invention provides a limb length measuring method and a limb length measuring device. In the embodiment of the invention, the rotation angle of a limb is obtained, the movement displacement of the limb is obtained, the length of the limb can be automatically calculated through the rotation angle and the movement displacement, manual measurement and input are not needed, the construction efficiency of a human body virtual model is greatly improved, in addition, errors are reduced, and the human body virtual model can be closer to the actual body of a user.

Description

technical field [0001] The invention relates to the technical field of limb length measurement, in particular to a limb length measurement method and a limb length measurement device. Background technique [0002] Virtual reality technology is a computer simulation system that can create and experience a virtual world. It uses computers to generate a simulated environment and immerses users in the environment. Virtual reality technology uses the data in real life, through electronic signals generated by computer technology, and combines it with various output devices to transform it into phenomena that people can feel. These phenomena can be real objects in reality. It can also be a substance that we cannot see with the naked eye, and it can be represented by a three-dimensional model. [0003] In a virtual reality scene, inertial motion capture is a full-body motion capture using inertial sensors. The goal is to enable the user's actions to be correctly mapped to the human...
