Embodiment Construction

[0025] The solution of the present invention will be further described in detail below.

[0026] In view of the content and key issues in the application of virtual reality equipment mentioned above, we have adopted the following technical route.

[0027] (1) Multi-target (hands) collaborative tracking based on the nuclear tracking framework

[0028] The present invention solves the problem of fast two-hand cooperative tracking under the framework of Kernel-based Tracking. For reliable tracking, there are two important factors to consider: one is a robust hand region characterization; the other is an objective function for optimized collaborative tracking.

[0029] 2D image appearance information can be used to provide information that characterizes image texture and shape, and 3D depth information can provide distance information from all visible points of each object in the scene to the camera. Therefore, the present invention starts from the texture and structural charact...

Abstract

The invention discloses a gesture identification control method used for virtual reality equipment. The virtual reality equipment comprises a plurality of 3D depth cameras and a controller. The method comprises the following steps that: establishing the bone and the three-dimensional model of a hand, tracking the hand through the depth cameras, optimizing a hand bone model so as to control the deformation of the three-dimensional model, quickly detecting an interaction function of the hand and environment in real time further according to the deformation information of the three-dimensional model, and realizing interaction between the user and the virtual environment. By use of the method, a calculated amount in the gesture control process of the virtual reality equipment is lowered, gesture comprehension accuracy is improved, and a quick and vivid interaction function between the user and the virtual environment is realized.

Description

technical field [0001] The invention belongs to the technical field of virtual reality, and in particular relates to a gesture recognition control method for a virtual reality device. Background technique [0002] In virtual maintenance applications, the interaction between man and machine is particularly important. Vision-based somatosensory interaction is one of the important technologies of human-computer interaction, and it is also one of the most natural means of human-computer interaction. It uses the position, direction and posture of the human hand and body as the input method of the computer to integrate the input space and the output space. Therefore, somatosensory interaction has gradually become a key technology for interactive command input in virtual maintenance. [0003] A very important part of somatosensory interaction is gesture interaction. The research on gesture analysis and interaction can be traced back to the 1980s. Grimes was first patented by AT&...
