Motion capture data presentation method and device based on multi-Kinect and UE4

Abstract

The invention relates to the field of computer graphic processing and provides a motion capture data presentation method and device based on multi-Kinect and UE4. The invention aims to solve the problems that a capture range is limited and a model skeleton structure and articulation point quantity are limited in animation display of motion capture data of kinect. The specific implementation mode of the method comprises the following steps: receiving skeleton data captured by a plurality of pieces of kinect, and calibrating human body skeleton data according to a preset coordinate transformation matrix to acquire coordinate data of each piece of human body skeleton data under a reference coordinate system to serve as reference skeleton data; performing weighted average processing to acquirean average skeleton of a person; transforming the average skeleton into role model data corresponding to a role model in a UE4 graphic program through a preset mapping relationship; according to theangle model data, using a UE4 engine to perform skeleton animation exhibition. The capture range is enlarged in the human body skeleton animation exhibition process; the skeleton structure and the articulation point quantity of a 3D model in the UE4 are not limited.

Description

Technical field [0001] The invention relates to the field of computer graphics vision and computer animation technology, in particular to a method and device for expressing motion capture data based on multiple Kinects and UE4. Background technique [0002] Motion capture is motion capture. The motion capture data is to set a tracker on the key parts of the moving object or person, or set a camera around to shoot the moving object or human body. The data obtained by the tracker or camera is processed by the computer to obtain the three-dimensional space coordinates data. Motion capture technology can be applied in fields such as film and television games, virtual reality, robot positioning and navigation, and product display. Based on the Microsoft Kinect sensor, it can capture the image information of the human body in real time and analyze the human body movement information. For example, it uses motion capture technology to classify dance movements, and visualizes the captur...

AI Technical Summary

Problems solved by technology

However, Kinect’s animation processing of motion capture data cannot be well integrated with the capture data of multiple kinects, and there are restrictions on the number of joint points and skeleton structure of the character’s skeleton. The animation displays Kinect human motion data
