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 human body motion enhanced visualization method and a human body motion augmented reality system. The method extracts human body skeleton motion information through a human body motion acquisition device, sets it as boundary conditions and external forces, and uses a method of computational fluid dynamics. The simulation of airflow movement is carried out on the layer, and the change of the density field under the airflow is displayed synchronously with the movement data, thereby enhancing the visualization effect of various actions, which is suitable for the visualization of small and instantaneous actions. The present invention automatically synthesizes visual data with enhanced motion effects onto the original human body action video through calculation, without artificially performing subsequent processing on the action data, and can be used in augmented reality and other fields in conjunction with augmented reality glasses or other camera-display integrated devices.

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...
