Example Embodiment

[0049] Such as figure 1 As shown, an augmented reality 3D drawing system based on gesture recognition includes the following units:

[0050] Hand trajectory tracking unit, which tracks the user's hands in real time and establishes a dynamic trajectory diagram;

[0051] A static gesture recognition unit that recognizes the hand information tracked by the hand trajectory tracking unit in real time and updates the state variable space;

[0052] Three-dimensional drawing unit, which maps the two-dimensional drawing trajectory to the three-dimensional space, and projects the virtual image of the three-dimensional space into the two-dimensional real scene image after operating the three-dimensional space according to the gesture;

[0053] A human-computer interaction interface unit, which includes a drawing interface and a function selection interface to realize real-time, pure gesture human-computer interaction without a mouse and keyboard. The drawing interface displays prompt information ...

Abstract

The invention discloses an augmented reality three-dimensional plotting system and method based on gesture recognition. According to the method, an effect of fusing virtual three-dimensional plottingand a real scenario is achieved on a concept of augmented reality, so that real-time interaction can be performed on a computer and a user. By virtue of real-time gesture recognition and hand motion track recognition, according to the system and method disclosed by the invention, the user is allowed to perform translation, three-dimensional rotation and far and near stretching operations on a two-dimensional plotting plane, and the virtual three-dimensional space is fused with an actual three-dimensional space, so that the effect of plotting in the real three-dimensional space is achieved. Thesystem and method disclosed by the invention can be applied to artistic creation, children education and work demonstration.

Description

technical field [0001] The present invention relates to the field of computer human-computer interaction, in particular to an augmented reality (Augmented Reality, AR) three-dimensional drawing system and drawing method based on gesture recognition. Background technique [0002] Human-computer interaction is a focus of the current information industry, and researchers from all over the world regard it as a key technology for research. After decades of development, the current human-computer interaction technology is gradually shifting from the computer-centered to the user-centered, from the command line interface, the graphical user interface, to the natural user interface (NUI, NaturalUser Interface) development process. In natural user interface interaction technology, gesture has become one of the research focuses of relevant personnel because of its flexible, intuitive and easy-to-learn advantages. [0003] Computer graphics rendering is an important research directio...
