Multi-mode coupled motion capture method and device

Abstract

The invention discloses a multi-mode coupled motion capture method and device. Various types of motion capture data are acquired, a reference coordinate system of the data is selected, and the data isconverted to obtained the data with a unified coordinate system; then coupling optimization is carried out on the captured various data; and the method comprises a data acquisition process, a data registration process, a data coupling process and a data publishing process. The multi-mode coupled motion capture device comprises motion capture equipment, a client-side, a server-side and a data acceptance client-side; the server-side comprises a data receiver, a data parsing and storage device, a data register, a data fusion optimizer and a data publishing module. The multi-mode coupled motion capture method and device have the advantages that multi-mode coupled motion capture optimization data can be acquired, the motion capture requirements of a single-user operation or multi-user cooperative operation are satisfied, the interactive efficiency between virtual and real environments is effectively improved, the immersion sense of users is improved, and the multi-mode coupled motion capture method and device can be widely applied to multiple fields.

Description

technical field [0001] The present invention relates to the technical field of motion capture, in particular to a multi-mode motion capture coupling method and device. Background technique [0002] Motion capture technology can obtain the motion state and posture of people or objects in the real environment, and its idea is generally considered to be the "Rotoscope" technology invented by Fleischer in 1915. Motion capture technology in a more modern sense was produced in the late 1970s by psychologist Johansson in the Moving Light Display experiment. In the 1980s, the research on human motion capture realized by computer began to appear. Universities such as Biomechanics Laboratory in the United States and MIT successively conducted research on this, which promoted the development of motion capture technology. For example, in 1983, MIT developed a set of A graphic marionette called "Op-Eye", this marionette served as the first "motion capture costume" and set the trend for ...

AI Technical Summary

Problems solved by technology

[0006] It can be seen that the obvious problems of the current motion capture technology include: first, the single-mode motion capture technology is still unable to meet the high requirements for the comprehensive capture accuracy of the user's overall and partial limbs; The effects of positioning accuracy and high convenience are not ideal, and the advantages cannot be complemented; third, once the single-mode motion capture data is lost, it cannot be recovered or compensated, which affects the user experience

For example, it is difficult to provide high multi-object capture capabilities and fine finger capture capabilities at the same time using existing motion capture technologies, and it is also difficult to meet the application requirements of high positioning accuracy and high convenience at the same time
