Problems solved by technology

In order to realize the interaction between the participant and the virtual environment, it is necessary to track the posture of the participant's head and the separation part. In the prior art, complex peripheral devices are used, such as gyroscopes, accelerometers, and rotation vector sensors, etc. Therefore, it not only increases the system cost, but also has the problem of limited tracking accuracy, which reduces the experience of the participants

specific example

[0085] The virtual environment generation controller includes two core functional modules, one is the attitude transformation calculation module of the head-mounted camera, and the other is the attitude transformation calculation module of the separate interactive device. These two functional modules can be integrated or set separately. When they are set separately, functional modules embedded in desktops, notebooks, mobile phones, chips, and smart glasses with attitude transformation calculations can be used respectively. The following is an example of setting these two function modules separately:

[0086] The spatial location division of this system includes three parts: the head-mounted device part, the separation part interactive device part and the fixed camera part:

[0087] The head-mounted device part is composed of a display device fixing frame, a bracket main body, an image observation window, a binocular lens, a camera acquisition module, a separation part interact...

Abstract

The invention provides a virtual reality interactive system and method based on machine vision. The method is: a virtual environment generation controller obtains the posture change information of the head of participant in a world coordinate system based on the feature point recognition technology of the machine vision and further obtains the posture change information of separation portion interactive equipment; and an overlapped virtual animation is generated under the condition of the motions of both the helmet equipment and the separation portion interactive equipment by combination of the aiming direction of the separation portion interactive equipment and the interactive command of the virtual environment, and the overlapped virtual animation is output to a display screen arranged in a clamping groove of the front end of the helmet equipment. The virtual reality interactive system and the method based on the machine vision has the advantages of being capable of realizing the output of the overlapped virtual animation under the condition of the motions of the helmet equipment and the separation portion interactive equipment, generating a more natural and smooth animation, and enhancing the experience of a player.

Description

technical field [0001] The invention relates to a virtual reality interactive system, in particular to a machine vision-based virtual reality interactive system and method. Background technique [0002] Virtual reality technology (Virtual Reality, VR) is a latest technology that integrates computer graphics, multimedia, artificial intelligence, multi-sensor, network and parallel processing technologies. Interactive 3D image world. In the realistic experience of perceptual behaviors such as seeing, hearing, touching and smelling, the participants can directly participate in the functions and changes of virtual objects in the environment, making people feel as if they are in a virtual world, creating an immersive experience. Feeling, namely: immersion (Immersion). [0003] In addition to the characteristics of immersion, virtual reality technology is also interactive, that is, participants can manipulate the virtual environment. In order to realize the interaction between t...
