Embodiment Construction

[0023] The accompanying drawings illustrate the technical solution of the present invention in detail. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] The present invention provides a human body motion enhanced visualization method, comprising the following steps:

[0025] Step 1, such as figure 1 As shown, the input data of the present invention are three-dimensional human body motion data and skeleton motion data extracted therefrom. Such data can be obtained through motion capture systems such as Vicon or depth cameras such as Kinect and their supporting skeletal motion extraction SDK.

[0026] If this data comes from a motion capture system, the skeleton animation is drawn directly and projected to the selected viewing angle as a traditional motion visualization method.

[0027] If the data comes from the depth camera, draw its RGB channel data, or draw the RGB channel data a...

Abstract

The invention discloses a body movement enhancement visualization method and a body movement augmented reality system. The method comprises the steps: extracting body skeleton movement information through body movement obtaining equipment; setting the body skeleton movement information as the boundary condition and an external force; carrying out the simulation of airflow movement at an overlapped layer through a method of computational fluid mechanics, and carrying out the synchronous display of the change of a density field under the airflow condition and the movement data, thereby improving the visualization effect of each type of movement. The method is suitable for the visualization of slight and instantaneous movement. Through the calculation and automatic synthesis of visual data with the enhanced movement effect to an original body movement video, there is no need to manually carry out the subsequent processing of movement data, and the method can cooperate with an augmented reality glasses or other camera display integrated equipment, and is used in the field of augmented reality.

Description

technical field [0001] The invention relates to the technical field of virtual reality and data visualization, in particular to a method for enhancing visualization of human body movements and a human body movement augmented reality system. Background technique [0002] Human body movements are common video content. A large amount of information about athletes can be obtained by observing human body movements. It has many applications in education, health, sports and other fields. Video recording and motion capture systems are common ways to acquire human motion data. Under such data acquisition means, because other high-dimensional data visualization technologies are not intuitive enough, the visualization of human motion data is mostly in the form of video and rod-shaped abstract skeleton movement. to visualize. Due to the limitation of human vision, this kind of intuitive human motion visualization method is better for smooth and obvious motion display, but cannot clearl...
